Safety vs Stress Signals: A Nervous System Reset

For the longest time, I believed health was about doing more. More supplements, more lab tests, more workouts, and more routines. I kept spreadsheets and detailed checklists of everything I was trying to do for my health. I thought if I just found the right combination and toughed it out long enough, I’d finally feel amazing.

But what actually changed everything for me wasn’t another protocol. It was a simple mental reframe that shifted how I think about health, healing, and life in general. It was the idea of focusing on sending safety signals to my body, instead of trying to force it into submission.

This mindset shift transformed the way I eat, move, rest, and even think. It helped me move out of a place of chronic low-level stress and into a state where healing actually became possible. If you feel stuck in a rut like I was, but can’t seem to pinpoint why, then read on!

Understanding the Nervous System

First, let’s take a look at the nervous system. Our nervous system operates in two main modes: sympathetic and parasympathetic. The sympathetic nervous system is responsible for the fight, flight, or freeze response. Our body activates this response when it senses danger or a threat. On the flip side, the parasympathetic system is responsible for rest, digestion, and healing.

Thanks to modern life, many of us spend the majority of our lives stuck in sympathetic mode. Even if we don’t feel mentally stressed, our bodies might still be receiving signals that we’re not safe.

I spent over a decade in that place. I didn’t understand that my constant doing, even the “healthy” stuff, was keeping me stuck and my body still didn’t feel safe enough to shift into healing mode. That’s where the concept of safety signals versus stress signals comes in.

What Are Safety and Stress Signals?

Stress signals are things that tell our bodies to stay on alert. These can be obvious mental stressors like arguments or deadlines, but also more subtle things. Under-eating, over-exercising, poor sleep, loneliness, negative self-talk, or even exposure to blue light at night send stress signals to our nervous system. 

Safety signals, on the other hand, are cues that tell the body it’s okay to rest and repair. These include things like nourishing food, deep sleep, human connection, hydration, sunlight, gentle movement, and kind self-talk.

When we focus on sending more safety signals, the nervous system can finally relax. And once it does, so many things start to improve, like our energy, digestion, mood, hormones, and even weight.

Rebuilding Safety Through Nutrition

One of the most powerful safety signals we can send to our body is through food. For a long time, I was under-eating, especially when I was trying to heal my thyroid and lose weight at the same time. I didn’t think of it as a stressor because I wasn’t (usually) skipping meals, but I wasn’t eating enough of what my body needed. 

When we don’t eat enough, our body gets the message that food is scarce. It perceives this as a threat and raises stress hormones, like cortisol. So instead of healing and repairing, our nervous system is on high alert. Overeating also puts stress on the body, especially if we’re overeating high-calorie, low-nutrient, processed foods.  

The shift happened when I started eating enough, especially focusing on protein, micronutrients, and minerals. I began to prioritize my first meal of the day, making sure it was packed with nutrients and protein, before I reached for any caffeine. I also stopped eating late at night, giving my body time to digest before bed.

Instead of approaching food from a mindset of restriction or control, I started asking myself, How can I nourish my body today? That shift alone brought noticeable improvements in my energy, mood, and sleep.

Sleep as a Safety Signal

We all know sleep is important, but I didn’t realize how much my nervous system was suffering from inconsistent or insufficient sleep. As a mom to quite a few kids, I haven’t always been able to get a full 8 hours!

Even skipping one hour of sleep can cause cortisol to spike and affect blood sugar and insulin. And when it comes to brain fog, some experts have compared just one night of six hours of sleep to being mildly intoxicated.

Making sleep a priority, especially with an earlier bedtime and consistent wake-up time, made a big difference for me. I noticed improvements in my heart rate variability, resting heart rate, and overall sense of calm. This can be difficult to do for moms, but the idea is to make sleep a priority. For me this meant no more cleaning the kitchen late at night or browsing social media after the kids went to bed!

Creating a calm sleep environment helped too. I turned my bedroom into a sleep oasis and kept it dark and cool with as little noise as possible. I reduced blue light exposure in the evening and found that my body started to naturally unwind and fall into deeper sleep.

Light and Circadian Rhythms

While I avoid blue light at night, it’s your friend during the daytime. Natural light is one of the most powerful but overlooked tools for supporting the nervous system.

Getting sunlight in the morning helps set the body’s internal clock and supports melatonin production at night for better sleep. Getting sunlight in the middle of the day boosts mitochondrial health, improves nutrient absorption, and supports hormone balance. I try to get at least 10 minutes of morning sunlight within 30 minutes of waking, often barefoot so I also get grounding benefits. Then I’ll take a few short walks with my weighted vest or sit on a lounge chair to soak up the afternoon sun. 

In contrast, blue light exposure at night tells the body it’s daytime, which can disrupt sleep and cause stress. I started using amber and red lighting in the evenings and wearing blue light blocking glasses when needed. I also switched to using warm light sources after sunset from lamps. These lamps are on a timer so I don’t even have to think about switching them on when the sun sets. 

Simple shifts in light exposure help my body feel more in tune with its natural rhythms. Plus, it reduced the constant background stress I didn’t even know was there.

Hydration and Mineral Balance

Dehydration is another common but often ignored stress signal. When we’re even slightly dehydrated, our blood thickens, our energy drops, and our body perceives that something is wrong.

But hydration isn’t just about drinking water. Our bodies need minerals, like magnesium, potassium, and sodium in order for water to actually be absorbed and used effectively. I started drinking mineral water in the morning, often outside in the sun. I also focus on staying hydrated between meals so that I’m not diluting my stomach acid needed for digestion. 

Not only does it help support my nervous system, but I notice more energy when I hydrate with plenty of minerals. 

Movement That Feels Supportive

Getting enough water is important, but so is getting enough movement. Exercise can either be a safety signal or a stress signal, depending on what our body needs at a given time.

When I was deeply stressed, intense workouts made things worse. My body craved gentle movements, like walking, swimming, or stretching. Over time, as my nervous system stabilized, I slowly reintroduced strength training and resistance exercises. Now you’ll find me doing sprints on the track field. 

My mindset has changed so I see movement as another way to support my body, not punish it. I aim for regular walks, mobility work, and body-friendly ways of moving throughout the day. There’s a time and a place for more intense exercise, but it can be too much when we’re in nervous system overload. 

Environmental and Emotional Signals

Even if we’re eating well and sleeping enough, our environment still sends signals to our nervous system. Synthetic fragrances, harsh cleaning products, synthetic clothing, and even clutter can all act as subtle stressors.

Our inner dialogue matters too. The way we speak to ourselves, whether with criticism or compassion, has a direct impact on how safe our nervous system feels. I noticed that I was saying things like “my body is attacking itself.” 

When I noticed negative thoughts, I asked, Would I say this to my child or my best friend? If not, it didn’t belong in my inner world either. Instead, I shifted my mindset to say something like, “My body is healing.” These shifts helped me create more safety from within.

Connection, Joy, and the Subtle Signals

Human connection is another deeply powerful safety signal. Eye contact, laughter, touch, and presence all tell our bodies we’re safe and supported.

Joy and finding happiness in even the little things in life are important here too. Things like singing, dancing, warm baths, humming, stretching, or even just watching the sunset are all ways to nurture the nervous system. The vagus nerve, which plays a big role in parasympathetic activation, responds to these small, joyful acts.

I also began to think about how my home environment could feel more supportive. I swapped harsh lights for gentle ones, removed synthetic fragrances, and made my bedroom a cozy space that truly felt safe. 

Final Thoughts on Safety Signals

The most important thing I’ve learned is that our bodies are always on our side. They are constantly working to protect us, even when it doesn’t feel that way. When we learn to communicate with our body instead of trying to fix or force it, everything changes for the better.

If you’re just starting on this path, I would encourage you to choose one small thing. Get morning sunlight. Drink mineral-rich water. Go to bed 30 minutes earlier. Eat a protein-rich breakfast. Whatever feels manageable and kind to your body. 

It’s not about doing more, but listening more to what our body is telling us.
