The nervous system is the body’s command centre and we rely on it to survive. It guides almost everything we think, feel, and do by allowing the body to process and respond to information – so it’s important to take care of it.
With that said, here are 10 science-backed ways to take care of your nervous system.
What is the nervous system?
The nervous system is the body’s internal communication system. It’s made up of two parts – the central nervous system (CNS) and the peripheral nervous system (PNS).
The CNS includes the brain and spinal cord, and the PNS is made up of all the remaining nerves in the body. The PNS can also be subdivided into smaller components: the somatic and autonomic nervous systems.
The somatic nervous system involves bodily responses that a person can command at will (for example, moving a muscle), and the autonomic nervous system is responsible for involuntary actions that we need to stay healthy (such as pumping blood).
Within the nervous system, nerve cells receive information through different bodily senses: smell, sight, sound, touch, and taste. This information is transported to and interpreted by the brain, so it can respond with the necessary body functions.
The nervous system guides almost everything we think, feel, and do; including functions like movement, memory, digestion, heartbeat, breathing, response to pain, and body temperature regulation. We rely on our nervous system every moment of every day to stay safe and healthy.
10 science-backed ways to take care of your nervous system
So what can you do to take care of your nervous system?
Research shows that several factors can increase the risk of nerve damage. However, while some of these, such as age, can’t be controlled, others, including lifestyle habits like smoking, can be.
Below, we’ll explore some ways you can take care of your nervous system…
1. Walk barefoot from time to time
Our feet have over 200,000 nerve endings, which is more per square inch than any other area of the body. Among other things, these nerve endings exist to send messages to the brain to help maintain balance while you walk. Like any other part of the nervous system, the nerve endings in your feet benefit from being stimulated.
Walking barefoot is a fantastic way to stimulate the body’s entire communication system. This study found that physical contact with the earth’s surface can help to regulate the nervous system and circadian rhythm; improving body temperature regulation, digestion, blood pressure, and hormone secretion.
2. Limit alcohol intake
Alcohol disrupts the brain’s communication pathways, which can make it more difficult to control balance, speech, memory, and other motor abilities. Long-term heavy drinking has been found to negatively affect the nervous system – for example, by altering neuron structure.
This study noted that alcohol can destroy brain cells and depress the central nervous system. So, excessive drinking over a long period of time may lead to issues with cognitive function and memory. Additional research suggests that prolonged heavy drinking may increase a person’s risk of dementia.
The NHS advises drinking no more than 14 units of alcohol a week, spread across three days or more. For guidance on unit size, head over to the NHS website. Alternatively, if you’d like to work towards cutting alcohol out of your diet entirely, you might be interested in our article; 13 affordable and tasty alcohol-free drinks.
3. Centre your diet around whole foods
Our diet plays a key role in allowing our nervous system to perform at its best. Experts advise eating whole, nutrient-rich foods, and limiting your intake of processed foods.
Unhealthy diets that are high in saturated fat and sugars are linked with chronic inflammation, which can increase the risk of nerve-damaging conditions like diabetes and autoimmune disorders.
This study also found a strong link between a high intake of ultra-processed foods and cognitive decline – including the ability to learn, reason, remember, and problem-solve.
4. Make sure you’re eating enough healthy fats
Contrary to diet culture beliefs, having enough fat in your diet is essential for health – and this includes the health of your nervous system.
Nerve cells are wrapped in a protective layer called the myelin sheath, which helps keep them healthy and functioning. There’s evidence to suggest that eating enough healthy fats can help to maintain the health of this protective coating by preventing it from eroding.
Examples of healthy fats include avocado, fatty fish, nuts, and seeds. If you’d like more ideas for ways to add healthy fats to your diet, the Mediterranean diet and foods rich in omega-3s are good places to start.
5. Exercise regularly
Staying active is important for nervous system health.
Among other things, exercise raises heart rate, which increases oxygen flow to the brain and releases hormones like serotonin. These hormones are important for brain cell and blood vessel health, as well as the development of new brain cells.
Exercise has also been found to enhance white matter structures in the brain (brain tissue which is responsible for passing messages throughout the nervous system), and improve neuroplasticity – which is the brain’s ability to adapt to and make new connections. Other studies have also found that engaging in regular exercise can reprogram ageing brains and counteract inflammatory changes that can impact brain function.

6. Make sure you’re getting enough nerve-friendly vitamins and minerals
Eating a healthy, balanced diet full of essential vitamins and minerals is important for overall health. And, alongside omega-3s, some vitamins and minerals are particularly important for nervous system health and function.
Vitamins B1, B6, and B12 are called neurotropic vitamins because they work together to energise nerves, repair nerve fibres, and protect nerves against environmental influences. For example, studies show that vitamin B1 serves as an antioxidant, B6 balances nerve metabolism, and B12 helps to keep the myelin sheath healthy (the protective coating at the end of nerves).
We also know from research that magnesium is essential for the survival of and function of neurons; brain cells rely on minerals like potassium to communicate with each other; and calcium plays a key role in nerve cell repairs.

7. Take steps to lower or regulate blood sugar levels
Having high blood sugar levels over a long period of time can damage the small blood vessels. This prevents sufficient oxygen and essential nutrients from reaching the nerves, which can harm them.
For this reason, neuropathy (nerve damage) is a common long-term complication of diabetes. Diabetic neuropathy can cause a range of unpleasant symptoms, including numbness – particularly in the hands and feet.
So, taking steps to lower or regulate your blood sugar levels is important for nervous system health. If you’d like some guidance on this, check out our article; 12 science-backed ways to lower (or regulate) blood sugar levels.
8. Aim to get your cholesterol and blood pressure levels in a healthy range
Just like high blood sugar levels, high cholesterol or blood pressure can have a negative effect on nervous system health.
For example, a common symptom of familial hypercholesterolemia (high cholesterol passed down from a relative) is a buildup of cholesterol deposits in the Achilles tendon, hands, or elbow tendons. If these deposits build up too much over time, they can begin to put pressure on the nerves in the hands, feet, ankles, and elbows.
The brain can also be negatively affected by high cholesterol and blood pressure. Research suggests that prolonged high blood pressure may play a role in dementia and cognitive decline by damaging arteries in the brain.
High cholesterol is also linked with a higher risk of diabetes, which increases the risk of neuropathy.
If you’d like to take steps to lower your cholesterol or blood pressure, it’s worth having a read of our articles; 5 tips to help lower cholesterol and 10 natural ways to lower blood pressure.
9. Take steps to manage stress
The nervous system plays a central role in our physical response to stress by generating what’s known as our fight or flight response.
While experiencing some stress can be beneficial (for example, it’s been linked with improved immunity and cognitive function), chronic stress can negatively impact our health, and our nervous system.
This is because when the body produces too much of the stress hormone cortisol, it can interfere with communication between neurons – potentially affecting memory and reflexes.
This study found that chronic stress led to the degradation of the brain cells that regulate neural communication (astrocytes). This is because, when under stress, astrocytes shrink away from synapses (the structures that allow information to pass from cell to cell via neurotransmitters), which disrupts communication between nerve cells.
For this reason, taking steps to manage stress levels is important for keeping your nervous system healthy. You’ll find plenty of tips, including breathing exercises for stress relief and simple stress-relieving activities, in the healthy mind section of our website.
10. Quit smoking
Nerves need sufficient blood flow to receive the oxygen and nutrients that allow them to function properly. It’s much more difficult for damaged nerves, or nerves that receive less than enough oxygen, to communicate with the brain and send proper signals.
As a result, smoking cigarettes – which narrow blood vessels and restrict blood flow – is strongly linked with an increased risk of nerve damage, and therefore neuropathy – leading to a range of potential symptoms like numbness and tingling.
With that said, quitting smoking can be one of the most beneficial steps you can take for your nervous system health. If you’d like some support, you can find information about stop smoking services on the NHS website.
