How to Reset Your Nervous System

If you find yourself juggling demanding careers, personal responsibilities and endless social media and phone notifications, you’re not alone. However, sooner or later, this always-on lifestyle catches up and fueled by caffeine and sugary snacks, the effects can often be worse.

Feeling wired but tired, racing thoughts at night, and constant snapping at loved ones are just a few of the signs that you need a reset. While many fear they are broken, instead, it’s just your nervous system doing exactly what it’s designed to do: protect you from perceived threats.

That’s not to say you have to put up with the state of stress. You might simply need to press pause, and it all comes down to knowing how to reset your nervous system.

Sympathetic vs Parasympathetic Nervous Systems

The body relies on two key branches of the autonomic nervous system to maintain balance, which are called the sympathetic and parasympathetic nervous systems.

The sympathetic nervous system is responsible for the fight-or-flight response. It releases our stress hormones, such as cortisol and adrenaline, to help the body respond to pressure.

The parasympathetic nervous system, which is probably more well known as our “rest and digest” state, supports our recovery, digestion, immune function and repair.

Ideally, the body should move fluidly between these two states depending on what is needed. But when we’re experiencing a lot of stress, overstimulation, and not enough rest, then it can make it more difficult for the nervous system to return to a calmer, regulated state.

The aim is to switch fluidly between the two instead of staying in one state over the other. That way, you can enjoy a fully regulated and balanced internal state.

Signs You Need to Reset Your Nervous System

Some of the most common signs of a dysregulated nervous system include:

Why Is It Important to Regulate Your Nervous System?

When your nervous system is in a good place, pretty much everything else follows.

Sleep gets better because your body feels safe enough to fully switch off and recover overnight. Your immune system works better too because when you are constantly stressed, the elevated stress hormones quietly chip away at your ability to fight back and bounce back from illness.

Digestion is another one people don’t always think about. When you’re stressed, your body is basically in a survival state, so things like breaking down food and absorbing nutrients get put on the back burner. That’s why a lot of people notice gut issues when they’re going through a stressful time.

And then there’s just how you handle life day to day. A nice, regulated nervous system takes the edge off your emotional reactivity. The little things dont hit you as hard and you’re better and more level headed to deal with whatever gets thrown at you without it potentially derailing your mood.

How to Reset Your Nervous System in Minutes and Reduce Stress Naturally

If you feel your anxiety spiking, there are a few little techniques that can calm your nervous system naturally and quickly.

Try Breathing Techniques

Here’s one simple technique. Take a deep breath in through the nose, followed by a shorter second inhale, then a long, slow exhale through the mouth. Repeating this several times may help encourage a more regulated physiological response.

Cold Exposure!

This sounds small, but splashing cold water on the face or briefly holding something cold might actually interrupt a stress response.

Hum or Sing to Yourself

Humming and singing may help stimulate the vagus nerve, which helps you feel relaxed. It can also indirectly help with emotional regulation and nervous system balance.

Grounding Techniques

The 5-4-3-2-1 method is very well known and commonly used grounding technique that helps people who are feeling anxious. It brings your attention back to the present moment.

Look for 5 things you can see, 4 you can touch, 3 you can hear, 2 you can smell and 1 you can taste. Grounding exercises like this may help reduce feelings of overwhelm and anxious thinking.

How to Reset Your Nervous System Long Term

Short-term nervous system regulation techniques can be really helpful when you’re feeling stressed in the moment, but long-term resilience is usually built through consistent daily habits and lifestyle patterns.

Prioritise Getting Morning Sunlight

Exposure to natural light within the first 30 minutes of waking up helps us regulate circadian rhythms, which impacts how much quality sleep we get, our hormone balance and nervous system function.

Move Your Body

High-intensity exercise is great for you and it can support overall health, but if it’s excessive training during periods of chronic stress or burnout then gentler forms of movement, such as walking, stretching or yoga, may help support relaxation and recovery.

Take Time Away From Your Phone

Constant notifications, screen exposure and digital stimulation can contribute to feelings of hypervigilance and mental overload. Creating tech-free periods, particularly during the first and last hours of the day, may help encourage a calmer and more regulated state.

The Role of Cellular Health and Energy

Even with healthy lifestyle habits in place, some people may still experience periods of fatigue, overwhelm or heightened stress sensitivity. This is partly because the nervous system relies heavily on adequate cellular energy to function efficiently.

The brain and nervous system require a significant amount of energy to support communication between neurons, regulate stress responses and maintain overall cognitive function. When the body is physically or mentally depleted, stress tolerance may feel lower and recovery can become more difficult.

One compound involved in cellular energy production is Nicotinamide Adenine Dinucleotide (NAD+), a coenzyme naturally found in every cell of the body. NAD+ plays an important role in energy metabolism, cellular repair and neurological function, including processes related to DNA repair and healthy cellular ageing.

As we age, our natural levels of NAD drop, which is why many people turn to NAD supplements. While it isn’t a magic pill for stress, maintaining healthy NAD+ levels can provide everything your body needs to handle the demands of modern life.

Making It Work in Real Life

Supporting your nervous system doesn’t have to mean completely changing everything about your lifestyle. The small things done consistently make the biggest differences over time in how we feel.

Things like getting outside for some morning sunlight, taking a few slower breaths when you feel tense, moving your body gently and without overdoing it or just giving yourself a minute to just pause – all of these things will add up when you’re working on wanting to reset your nervous system.

Some people also bring in supplements to sit alongside these habits. NAD+ precursors, which support energy at cellular level. They’re not a fix on their own, and they’re not meant to replace good sleep, eating well, or actually managing your stress, but for some people they can be a nice addition to the mix.

Supporting Your Nervous System Naturally

You don’t need to have a perfect plan or routine to start looking after your nervous system. A lot of it just comes down to noticing and catching moments in your day where you can slow down and give your body a chance to reset.

Something as simple as one slow, intentional breath genuinely can do something. It sounds too easy, but it says to our body that it’s safe and that’s where resetting your nervous system starts. Build enough of those small moments together and over time you’ll notice you’re more resilient, you recover faster and life’s inevitable stress doesn’t get to you quite as much as it used too.

And when you’re ready to support that process from the inside out, NAD+ EN CASA can help.
