Why does physical activity have a positive effect on mental health?

Published Aug 29, 2026 • By Léonie Guerut

Physical activity is often associated with its positive effects on the body: improved physical fitness, prevention of certain diseases, maintenance of mobility … But its effects on mental health are also of great importance

Regular exercise can help reduce stress, improve mood, and promote better emotional balance. These benefits apply to everyone, including those living with a chronic illness.

Why does physical activity affect your mood? What mechanisms explain these effects? And how can we incorporate more exercise into our daily lives?

Why does physical activity have a positive effect on mental health?

Why does physical activity also improve mental health?

Physical activity isn’t just about strengthening muscles or improving endurance. It also has a direct impact on how the brain functions.

During physical exertion, the body releases various substances that help regulate mood and well-being. This can create a sense of calm and contentment and help you manage your emotions more effectively.

In the long term, regular exercise can help alleviate symptoms associated with stress, anxiety, or low mood.

How does physical activity reduce stress?

Stress leads to a strong activation of the body. Physical activity helps reduce this tension by providing a moment of relaxation and allowing the body to release pressure.

Regular exercise can also improve your ability to cope with stressful everyday situations. The body becomes more resilient to the effects of stress, and your sense of control can increase.

Even a gentle activity like a daily walk can have positive effects.

Why does exercise improve mood?

Physical activity stimulates the production of substances that are important for well-being, particularly endorphins, which are sometimes referred to as “happiness hormones.”

These mechanisms can promote the following:

  • a better mood
  • fewer negative thoughts
  • a sense of relaxation
  • greater self-confidence

Physical activity can also provide a sense of accomplishment, especially when you make progress at your own pace or achieve goals that match your abilities.

Can physical activity help with anxiety or depression?

Yes. Numerous studies show that regular physical activity can have a positive impact on depressive and anxiety symptoms.

While it is not a substitute for medical treatment when necessary, it can be part of a holistic care plan. For some people, it helps them return to their daily routines, regain self-confidence, and gradually emerge from isolation.

Group physical activities can also promote social interaction, which plays an important role in mental well-being.

Why does exercise also help you sleep better?

Sleep and mental health are closely linked. Sleep disturbances can exacerbate stress and fatigue, while a low mood can interfere with sleep.

Regular physical activity helps regulate the sleep-wake cycle and can improve sleep quality. Better sleep helps people manage their emotions more effectively in everyday life.

However, you should avoid very intense activities right before bedtime, as they can sometimes make it harder to fall asleep.

Is physical activity beneficial for people with chronic illnesses?

Yes. For people living with a chronic illness, staying active can have a positive effect not only on the body but also on mood.

The illness can sometimes lead to limited activity, a feeling of isolation, or a loss of self-confidence. An adapted activity makes it possible to gradually reclaim an active role in daily life.

The goal isn’t necessarily to engage in intense sports, but rather to find an activity that’s compatible with one’s own abilities and preferences.

What kind of physical activity should you choose to improve your well-being?

The best activity is one that you can do regularly and enjoy.
Depending on your individual abilities, this could include the following:

  • Walking
  • Cycling
  • Swimming
  • Gentle exercises such as yoga or tai chi
  • Gardening or everyday physical activities

It’s important to adjust the intensity to your own health condition and, if in doubt, ask a healthcare professional for advice.

How do you get started when you’re lacking energy or motivation?

A gradual approach is often best. Here are some tips that can help:

  • Choose an activity you enjoy
  • Set simple and realistic goals
  • Gradually increase the duration or intensity
  • Incorporate exercise into your daily routine
  • Prioritize consistency over performance

Even just a few minutes of exercise a day can be a first step in the right direction.

What to keep in mind

Physical activity plays an important role in mental health. It can help reduce stress, improve mood, promote better sleep, and boost self-confidence. Its benefits don’t depend solely on the intensity of the effort: Even moderate activity, when done regularly, can contribute to mental well-being. Exercising at your own pace is a simple way to take care of your body and mind.

An important note before changing your exercise routine

Before starting a new exercise program or increasing your activity level, you should discuss this with your doctor or a healthcare professional, especially if you have a chronic condition, persistent pain, or physical limitations.

Your doctor can recommend an activity that suits your health condition, abilities, and goals. Physical activity should be introduced gradually, without causing severe pain or excessive fatigue. If you experience unusual symptoms, an increase in pain, or severe fatigue after exercise, do not hesitate to seek your doctor’s advice.
