How Exercise Reduces Stress

Why hitting the gym has a positive effect.

Stress — and how to reduce it — is one of those ubiquitous conversation topics that can be heard almost anywhere, from the doctor’s office to a dinner party. And it’s no wonder, as everyone experiences some level of stress and chronic stress can even put.

Now that we’ve shared a bunch of the bad news, here’s some good: exercise can reduce stress. In fact, numerous studies have described an association between physical activity and general wellbeing and mood.1,2

Exercise can help improve mood.

When mood has been measured immediately before and after physical exertion, the results are overwhelmingly positive. Specifically, exercise training can reduce anxious mood in both those with high anxiety or those with a typical level.3 Although more studies are needed, generally exercise is associated with a mood boost.

Similar to how exercise can enhance mood, it can also contribute to the reduction of anxiety. One literature review combined the results of three large studies and concluded that self-reported levels of exercise correlated with better mental health, including fewer symptoms of anxiety and depression.

How does exercise do this? The reasons are complex, but one theory is that exercise triggers certain events inside your body, leading to higher resilience against stress-related disorders.

Exercise might have lasting benefits.

There is some evidence that physical activity might help reduce risk of future stress symptoms. In a recent meta-analysis of 13 studies on the topic, the combined results showed a 22% reduced risk of developing depressive symptoms for the active groups in the studies.

More research is needed, but many studies show that stress sensitivity can be reduced after exercise, helping your body resist the ramifications of stressors.

In fact, exercise is an emerging therapy for the elderly, as there is some evidence that physical exertion might mitigate the brain degeneration associated with Alzheimer’s disease and old age.4

Exercise might even help improve sleep.

Although it might seem counterintuitive, exercise could even have a beneficial effect on sleep quality. One recent meta-analysis that gathered current studies on the topic featuring older adults (those over 40), found that exercise training improved sleep quality for those studied. So, although participants didn’t necessarily sleep more, they slept better.5

Before starting or modifying your exercise plan, it’s important to talk to your doctor.
