The Physical Foundation That Reduces PTSD Risk & Why Sleep, Nutrition & Exercise Matter More Than Mental Toughness

Behind every badge, there's a story.

A story of courage, sacrifice, and relentless pursuit of justice.

But there's also a story that often goes untold.

A story of the mental and emotional toll that policing takes on those who answer the call.

Welcome to Police Speak, the podcast that delves into the raw realities of police work and explores the path to resilience.

Each week, we'll unpack harrowing police encounters, dissect their psychological impact, and equip you with the tools to safeguard your mental well being.

So turn up the volume and prepare for our next journey.

Welcome back to Police Speak.

This is our final episode in the series on the predictive six factor resilience model.

If you're just joining us, Police Speak is a podcast that explores the psychological impact of critical incidents in law enforcement.

Throughout this series, we've been using the Predictive Six Factor Resilience Model, or PR6, as a framework to help you understand how to build resilience before trauma hits and how to recover when it does.

Today, we're talking about the health domain, and I have to tell you, this might be the most overlooked aspect of resilience in law enforcement.

When people think about building resilience, they usually think about mental toughness, positive thinking, having good coping skills, and yes, all of that matters.

We've spent the last six episodes talking about vision, composure, reasoning, tenacity, and collaboration.

And all of those domains are critical.

But here's what a lot of people miss.

All of those psychological resilience factors rest on a physical foundation.

Your brain is an organ.

It's part of your body.

And the health of your body directly impacts the health of your brain, which directly impacts your ability to regulate stress, process trauma, and maintain resilience.

You can have the best mindset in the world, but if you're chronically sleep deprived, eating garbage and never exercising, your brain isn't going to have the resources it needs to function optimally.

Your resilience is going to suffer no matter how mentally tough you think you are.

So today we're going to talk about why the health domain is foundational to everything else.

And we're going to get specific about what you can actually do to strengthen this domain.

Let's start with the neuroscience, because understanding what's happening in your brain will help you understand why physical health matters.

So much for mental resilience.

There's a protein in your brain called brain Derived Neurotrophic factor, or bdnf.

You can think of BDNF as fertilizer for your brain.

It promotes the Growth of new neurons strengthens connections between existing neurons and protects neurons from damage.

BDNF is absolutely critical for neuroplasticity, your brain's ability to adapt and change in response to experience.

Now here's where it gets interesting.

Your lifestyle directly affects your BDNF levels, and I mean directly.

Regular exercise increases BDNF production, particularly aerobic exercise, running, cycling, swimming, anything that gets your heart rate up.

When you exercise, your muscles release chemicals that cross the blood brain barrier and trigger BDNF production in your hippocampus, which is crucial for memory and emotional regulation.

Healthy Nutrition also affects BDNF.

A diet high in omega 3 fatty acids, antioxidants, and whole foods supports BDNF production.

On the flip side, a diet high in sugar, processed foods, and unhealthy fats actually down regulates bdnf.

You're literally making it harder for your brain to adapt and heal.

And sleep quality sleep is essential for BDNF production and for the consolidation of memories and learning.

When you're sleep deprived, your BDNF levels drop, your hippocampus doesn't function as well, and your prefrontal cortex struggles to regulate your limbic system.

So when we talk about the health domain, we're not talking about some vague idea of wellness.

We're talking about concrete, measurable impacts on your brain chemistry and your brain's ability to handle stress and trauma.

Let me give you an example.

I've heard stories from other officers and trainers about situations like this one.

There was an officer who was about 10 years into his career.

Let's call him Marcus.

Marcus was good at his job, well respected, no major complaints.

But over the years, he developed some pretty unhealthy habits.

He was working a lot of overtime trying to save up to buy a house.

That meant 12, 14 hour shifts, sometimes several days in a row.

He was sleeping maybe five hours a night on average, sometimes less.

He was eating poorly because he was always on the go.

Fast food in the patrol car, energy drinks to stay awake, whatever was quick and convenient.

He'd gained about 40 pounds over the years, but kept telling himself he'd deal with that later.

He used to work out regularly when he first got on the job, but he'd stopped a few years back.

Too tired, too busy, and honestly just didn't feel motivated anymore.

For a while, Markus thought he was handling everything fine.

Sure, he was tired, but that's just part of the job, right?

Everybody's tired.

But then Marcus caught a bad call.

A vehicle accident.

With multiple fatalities, including two kids.

It was traumatic, but Marcus had been through difficult calls before.

He figured he'd be fine.

Except he wasn't fine.

In the weeks after that call, Marcus fell apart in a way he never had before.

He developed full blown PTSD symptoms.

Nightmares, flashbacks, hypervigilance, panic attacks.

He couldn't function.

He ended up on administrative leave and in intensive therapy.

Now here's the Was it just the trauma of that call that caused Marcus's breakdown?

Or was it the fact that his brain was already compromised from years of sleep deprivation, poor nutrition, and lack of exercise?

The answer is both.

The traumatic call was the trigger, but Marcus's poor physical health had eroded his resilience to the point where his brain couldn't handle the stress.

Think about it like this.

Imagine your resilience is like a dam holding back water.

The trauma is the water.

If your dam is strong and well maintained, it can handle a lot of water.

Even when there's a big storm, a critical incident, the dam holds.

But if your dam has been neglected for years, if it has cracks and weak points, if the foundation has eroded, then even a moderate storm might cause it to fail.

That was Marcus.

His health domain had been neglected for so long that when a significant stressor came along, his system couldn't handle it.

So let's talk about the three main components of the health sleep, nutrition, and exercise.

We'll start with sleep, because it's probably the most important and the most neglected.

The research on sleep is unambiguous.

Chronic sleep deprivation has profound negative effects on your physical and mental health.

It impairs your cognitive function, your emotional regulation, your immune system, your cardiovascular health.

It increases your risk of obesity, diabetes, depression, anxiety, and a whole host of other problems for first responders.

Specifically, sleep deprivation is associated with higher rates of ptsd, higher rates of depression, increased risk of accidents both on and off duty, and increased likelihood of using excessive force.

Your brain needs sleep.

During sleep, your brain consolidates memories, clears out metabolic waste products, repairs, damage, and regulates your emotional state.

When you don't get enough sleep, all of those processes are impaired.

So how much sleep do you need?

The research says seven to nine hours per night for adults.

Some people can function okay on six, but that's rare.

And if you're consistently getting less than six hours, you're accumulating what researchers call sleep debt.

And it's affecting your performance whether you realize it or not.

Now, I know what some of you are thinking.

Seven to nine hours.

That's impossible.

With my schedule, I work rotating Shifts.

I have court appearances.

I have a family.

There's no way I can get that much sleep.

And look, I get it.

Shift work makes it really hard to maintain healthy sleep patterns.

But here's the thing.

If you don't prioritize sleep, your body will eventually force you to prioritize it through illness, injury or mental health crisis.

So what can you do?

First, take sleep seriously.

Treat it like the critical physiological need that it is, not like something you can just skip when you're busy.

Second, develop good sleep hygiene.

That means keeping your bedroom dark, cool and quiet.

It means avoiding screens for at least an hour before bed because the blue light interferes with melatonin production.

It means avoiding caffeine in the second half of your shift.

It means having a consistent bedtime routine that signals to your body that it's time to wind down.

If you work night shift, blackout curtains aren't optional, they're essential.

Your body needs darkness to produce melatonin and regulate your circadian rhythm.

Third, if you're working rotating shifts, talk to your department about the schedule.

Research shows that rotating forward days to evenings to nights is much easier on your body than rotating backward.

And having at least 48 hours off between shift changes gives your body time to adjust.

Finally, if you're having persistent sleep problems, if you have insomnia or sleep apnea, or you're just consistently not sleeping well, see a doctor.

This isn't something to just live with.

Sleep problems are treatable, and treating them can dramatically improve your overall health and resilience.

Let's talk about what you're putting in your body, because it matters more than you might think.

Your brain is an energy intensive organ.

It's only about 2% of your body weight, but it uses about 20% of your body's energy.

What you eat directly affects your brain's ability to function.

Diets high in processed foods, sugar and unhealthy fats are associated with inflammation, which affects brain function.

They're also associated with lower BDNF levels, which means your brain has less capacity to adapt and heal from stress.

On the other hand, diets rich in omega 3 fatty acids, antioxidants, whole grains, fruits and vegetables support brain health.

They reduce inflammation, support BDNF production, and provide the nutrients your brain needs to function optimally.

The research specifically on first responders shows that poor nutrition is associated with higher rates of depression, anxiety and burnout.

It also contributes to obesity, cardiovascular disease and diabetes, all of which are more common in law enforcement than in the general population.

Now, I'M not going to stand here and tell you that you need to eat a perfect diet every single day.

That's not realistic, especially when you're working patrol and grabbing meals when you can.

But here are some practical things you can do.

First, plan ahead.

Pack healthy snacks and meals when you know you're going to be on shift for a long time.

String cheese, nuts, fruit protein bars, sandwiches on whole grain bread.

These are all easy to pack and way better for you than hitting the drive thru three times a shift.

Second, stay hydrated.

Drink water throughout your shift, not just when you're thirsty.

Dehydration affects your cognitive function, your mood and your energy levels.

And I'm talking about water, not energy drinks or soda.

Those might give you a short term boost, but they're terrible for you long term.

Third, be mindful about alcohol.

Look, I know that a lot of officers use alcohol to unwind after a shift and having a beer or two occasionally is probably not a big deal.

But if you're drinking every night, if you're drinking to cope with stress, if you're using alcohol to help you sleep, that's a problem.

Alcohol might make you feel relaxed in the short term, but it disrupts your sleep quality.

It affects your mood and it can lead to dependence.

There are healthier ways to manage stress.

Fourth, pay attention to how different foods make you feel.

Some people feel energized after eating certain foods, while others feel sluggish.

Your body is giving you information.

Listen to it.

If you notice that certain foods consistently make you feel tired or foggy or irritable, consider eating less of those foods.

And finally, if you're significantly overweight, if you have high blood pressure or high cholesterol or pre diabetes, take that seriously.

These are warning signs that your physical health is compromising your resilience.

Talk to your doctor.

Consider working with a nutritionist.

Make a plan to address it because this stuff catches up with you.

Let's talk about physical fitness, because this is where a lot of officers start strong and then fall off over the years.

When you first get hired, you're motivated, you're working out regularly, you're in decent shape.

But then you get a few years into the job, life gets busy and the workouts start to slip.

Here's why that's a problem.

Exercise is one of the most powerful tools you have for building resilience.

Regular aerobic exercise increases BDNF production, improves hippocampal function, reduces inflammation, improves sleep quality, regulates mood, and reduces symptoms of depression and anxiety.

It literally makes your brain.

More resilient exercise also improves your cardiovascular health, helps you maintain a healthy weight, strengthens your bones and muscles, and increases your energy levels.

All of which makes you better able to handle the physical demands of the job.

The research on first responders specifically shows that officers who exercise regularly have lower rates of ptsd, lower rates of depression, better stress management, and better overall quality of life.

So how much exercise do you need?

The American Heart association recommends at least 150 minutes of moderate intensity aerobic activity per week, plus strength training at least two days per week.

That breaks down to about 30 minutes of exercise five days a week.

That's it.

Thirty minutes, a short run, a bike ride, a workout at the gym, even a brisk walk.

And here's the thing.

You don't have to be training for a marathon.

You don't have to be doing CrossFit six days a week.

Moderate intensity exercise where you're working hard enough to raise your heart rate but you can still carry on a conversation is enough to get most of the benefits.

The key is consistency.

Exercising five days a week for 30 minutes is going to do a lot more for you than killing yourself at the gym for two hours once a week and then doing nothing the rest of the week.

Now let me talk about one more aspect of the health domain that's particularly relevant for law enforcement Shift work, especially rotating shifts, is really hard on your body.

It disrupts your circadian rhythm, which is your body's internal clock that regulates sleep hormone production, metabolism, and a whole bunch of other physiological processes.

Research shows that shift workers are at higher risk for cardiovascular disease, gastrointestinal problems, metabolic disorders, depression, and certain types of cancer.

They also have higher rates of accidents and errors on the job because their cognitive function is impaired.

Unfortunately, if you're in law enforcement, shift work is probably unavoidable, but there are things you can do to minimize the damage.

First, as I mentioned earlier, advocate for forward rotating shifts rather than backward rotating if your department has any flexibility on that.

Second, when you switch from night shift to day shift or vice versa, give yourself time to adjust.

Don't switch your schedule abruptly.

Gradually shift your sleep and wake times over a few days if you can.

Third, use light strategically.

Bright light exposure helps regulate your circadian rhythm.

If you're working nights, expose yourself to bright light during your shift and then use blackout curtains to keep your bedroom dark when you sleep during the day.

If you're working days, get some sunlight in the morning to help you wake up.

Fourth, be extra vigilant about sleep, hygiene, nutrition and exercise.

When you're working shifts, your body is already under stress from the disrupted circadian rhythm, so you need to be even more careful about supporting your health in other ways.

And finally, recognize that shift work takes a toll if you're struggling, if you're chronically exhausted, if your mental health is suffering, if your relationships are falling apart, consider whether a scheduled change might help.

Maybe you can move to a unit that has more regular hours.

Maybe you can request permanent days or permanent nights rather than rotating.

Maybe you're at a point in your career where you need to prioritize your health over other considerations.

There's no shame in making changes to protect your health.

This job is a marathon, not a sprint.

If you burn yourself out in the first 10 years, you're not going to make it to retirement.

Let me come back to Marcus's story and show you what happened when he started taking his health domain seriously.

After Marcus had his breakdown, he went on administrative leave and started working with a therapist who understood trauma.

But the therapist also talked to him about his lifestyle, and she helped him see how his poor physical health had undermined his resilience.

So Marcus made some changes.

Big changes.

He cut back on over time.

It was a financial hit, but he realized that no amount of money was worth his mental health.

He started sleeping seven to eight hours a night consistently.

It took a few weeks for his body to adjust, but once it did, he he felt dramatically better.

He started meal prepping on his days off, so he had healthy food available during his shifts.

He quit the energy drinks and started drinking water instead.

He lost some of the weight he'd gained, and he started exercising again.

Nothing crazy, just 30 minutes of running or cycling five days a week.

But the difference it made was remarkable.

He had more energy.

His mood improved.

He slept better.

He felt more able to handle stress.

It took about six months, but Marcus was able to return to full duty.

And not only that, but he was in better shape physically and mentally than he'd been in years.

He still carries the weight of that traumatic call that doesn't just go away, but his brain is now healthy enough to process it, to integrate it, to live with it without falling apart.

That's the power of the health domain.

When your physical health is strong, all of your other resilience domains work better.

You have more capacity to regulate your emotions, to think clearly, to persevere through difficulties, to maintain relationships.

But when your physical health is compromised, everything else becomes harder.

So let me bring this all together and connect the health domain to the other five PR6 domains because that's really what this whole series has been about, understanding how all six domains work together to create comprehensive resilience.

Health and composure when you're sleep deprived, poorly nourished, and not exercising, your limbic system becomes hyperreactive.

Your amygdala is more easily triggered, your HPA axis stays elevated.

It becomes much harder to regulate your emotions and manage your stress response.

On the other hand, when your physical health is strong, your prefrontal cortex functions better and you have more capacity to downregulate that limbic activation.

Health and reasoning.

Sleep deprivation and poor nutrition impair cognitive function.

Your prefrontal cortex and your anterior cingulate cortex don't work as well when your body isn't healthy.

This makes it harder to think clearly, solve problems, and avoid getting stuck in negative thought patterns.

When your physical health is strong, your cognitive function improves and you can think more flexibly and realistically about challenges.

Health and tenacity when you're chronically exhausted and unhealthy, you just don't have the energy to persevere through difficulties.

Your motivation suffers.

Your ability to bounce back from setbacks is impaired.

But when your physical health is strong, you have more mental and emotional energy to devote to working through challenges.

You can maintain that realistic optimism we talked about in the tenacity episode.

Health and collaboration.

Your physical health affects your relationships.

When you're tired and irritable because you're not sleeping or eating well, you're more likely to snap at people.

You're less patient, less empathetic, less able to connect meaningfully with others.

But when you're healthy, you have more capacity for the emotional regulation and presence that strong relationships require.

Health and vision.

When your physical health is poor, it's really hard to maintain a sense of hope and purpose.

Everything feels harder.

Everything feels heavier.

But when your body is healthy, it's easier to see beyond immediate difficulties and stay connected to your larger sense of meaning and purpose.

See how it all connects.

The health domain is the foundation.

When that foundation is strong, all of the other domains work better.

But when that foundation is crumbling, everything else becomes harder.

So what can you do today to start strengthening your health domain?

First, assess where you are.

Be honest with yourself.

How much sleep are you actually getting?

What's your diet really like?

How often are you exercising?

Don't judge yourself.

Just gather the data.

Second, pick one thing to work on.

Don't try to overhaul your entire life at once.

Maybe you start by committing to seven hours of sleep a night.

Or maybe you start meal prepping on Sundays.

Or maybe you commit to walking for 30 minutes three days a week.

Pick one thing and build from there.

Third, track your progress.

Use your phone.

Use a journal.

Use whatever works for you, but pay attention to how you feel as you make changes.

Most people are amazed at how much better they feel when they start prioritizing sleep, eating better, and exercising regularly.

Fourth, get support.

Talk to your spouse or partner.

Work out with a buddy.

Join a department fitness challenge.

Make it social.

Make it fun.

You're way more likely to stick with it if you're not doing it alone.

Fifth, be patient with yourself.

You didn't get into poor health overnight, and you're not going to get healthy overnight.

This is about building sustainable habits over time.

Focus on progress, not perfection.

And finally, remember why you're doing this.

You're not just trying to lose weight or look good.

You're building the physical foundation that your brain needs to handle the incredible stress and trauma that comes with this job.

You're investing in your ability to serve your community for the long haul.

You're protecting your mental health so you can be there for your family.

Now I want to share some really important research that connects directly to what we're talking about today.

Recent research on the PR6 model has identified something called the 85% resilience threshold.

Here's what that means.

When People reach a PR6 score of 85% or higher, meaning they're scoring at least 85% across all six resilience domains, something significant happens.

They experienced dramatic improvements in mental health protection.

The research found that people at this high resilience level had a 5.9 fold reduction in emotional vulnerability, a 5.6 fold reduction in depression symptoms, and a 4.2 fold reduction in anxiety symptoms.

They also showed a 2.9 fold reduction in neuroticism overall, along with 52% higher conscientiousness and 65% higher extraversion.

Now, why am I telling you this in the health episode?

Because you can't reach that 85% threshold if your health domain is neglected.

You might have great vision, strong composure skills, excellent reasoning abilities.

But if you're sleep deprived, eating poorly, and never exercising, your overall resilience score is going to be dragged down.

The health domain is what we call a foundational domain.

It supports all the others.

And if you want to reach that protective 85% threshold where your brain has significant protection against PTSD, depression, anxiety, and other mental health challenges, you need to take your physical health seriously.

Think of it this reaching 85% resilience is like reaching a tipping point where your mental health has robust protection against the kind of trauma and stress you face in law enforcement.

But you can't get there if your foundation is weak.

So here we are at the end of this series on the Predictive six Factor Resilience model.

We've covered all six Vision, Composure, Reasoning, Tenacity, Collaboration, and Health.

And here's what I want you to take away from all of Resilience isn't about being invincible.

It's not about never struggling or never needing help.

Resilience is about having a comprehensive set of skills across all six domains that help you navigate adversity, process trauma, and keep moving forward.

You can start building that resilience today.

You don't have to wait until after a critical incident.

In fact, you shouldn't wait, because the time to build resilience is before you need it most.

Start with small changes.

Pick one domain that feels weakest for you and work on it.

Maybe that's improving your sleep habits.

Maybe that's reaching out to strengthen a relationship.

Maybe that's developing a clearer sense of your purpose in this work.

Maybe that's learning some breathing techniques to manage your stress response.

You don't have to do everything at once.

You don't have to be perfect.

Just start somewhere and then keep going.

Remember, this job is going to test you.

It's going to throw things at you that are hard, things that are painful, things that shake you to your core.

That's the nature of law enforcement.

We signed up to run toward danger, to see things that most people will never see.

To carry burdens that most people will never have to carry.

But you don't have to carry those burdens alone.

And you don't have to just white knuckle your way through until retirement, barely holding on.

You can build genuine, sustainable resilience that allows you not just to survive this job but but to thrive in it.

To do meaningful work, to maintain healthy relationships, to have a life outside the badge that brings you joy.

That's what the PR6 model is about.

That's what resilience training is about.

That's what programs like Resilience, First Aid and HEART are designed to help you do.

If you're struggling right now, please reach out.

Talk to peer support, talk to a chaplain.

Talk to a mental health professional who understands first responder culture.

You use the tools and frameworks we've discussed in this series.

And if you're not struggling right now, use this time to build your resilience.

Strengthen all six domains while you have the capacity to do so because you're going to need that strength someday.

Thank you for listening to the series.

Thank you for the work you do every day.

Thank you for being willing to learn about resilience and to invest in your own well being.

We're going to go back to our regular programming, sharing stories about critical incidents and the journey of healing that follows, but I hope this series has given you a framework for understanding those stories in a deeper way and for understanding your own experiences as well.

Take care of yourselves, take care of each other, and remember, resilience isn't something you either have or you don't have.

It's something you build one day at a time, one domain at a time.

Stay safe out there.
