Have a theological question?

Physical exercise and stress have a two-way relationship: exercise can reduce stress, and stress can make it harder to stay active. Regular exercise is associated with better emotional resilience, lower resting heart rate, and less decline in positive mood after acute stress.

Reviews and recent studies also support the idea that physical activity can buffer the effects of stress on daily wellbeing. The relationship also runs the other way: higher stress often predicts less physical activity or weaker exercise follow-through, especially when stress is anticipated in advance.

A review of the literature found that most studies show stress impairs efforts to be physically active. Exercise reduces stress through neurochemical changes like lowered cortisol and adrenaline, plus boosted endorphins and serotonin, which foster relaxation and mood elevation.

Psychologically, it builds resilience by limiting emotional drops after stressors and dampening reactivity in the brain’s stress circuits. Exercise counters the body’s stress response by reducing hormones like cortisol and adrenaline while triggering endorphins, the brain’s natural painkillers and mood elevators, for a runner’s high effect.

It also promotes neuroplasticity in the serotonergic system, helping limit serotonin spikes that worsen stress behaviours, and boosts prefrontal cortex activity to inhibit overactive stress responses. Studies show regular exercisers have lower resting heart rates, less mood decline after acute stress, and better recovery from emotional hits compared to sedentary people.

Moderate aerobic or mixed training consistently lowers perceived stress, anxiety, and depression symptoms, with even weekly sessions yielding dose-response benefits. Randomized trials confirm exercise neutralizes cardiac reactivity to stressors, cuts stress hormones, and improves quality of life.

Acute bouts buffer immediate stress impacts, while habitual activity builds long-term resistance via better sleep, circadian regulation, and coping ability. If you want to use exercise for stress relief, the most sustainable option is usually moderate, regular activity you can actually keep doing, rather than intense workouts you dread.

Even a short session can help, and the benefit tends to come from consistency more than perfection. For quick stress relief, the best exercise choices are usually brisk walking, dancing, swimming, and light bodyweight workouts. These are commonly recommended because they combine movement with breathing or rhythmic focus, which can calm the body and mind fast.

Brisk walking, especially in nature, is a fast, low-barrier way to lower tension and reset your mood. Dancing works well when you want stress relief plus a mood boost. Swimming can feel especially calming because the water and repetitive motion help narrow attention and reduce arousal.

Short strength sessions like squats, push-ups, or lunges can help if you prefer something more active. If you want the quickest, simplest answer: go for a 10–20 minute brisk walk, or do 5–10 minutes of slow stretching with deep breathing. If you are very tense, a brief walk plus a few slow breaths is often easier to do immediately than a harder workout.

When stress is very high, an extremely intense workout can sometimes feel overwhelming rather than soothing, so a moderate and doable activity is usually better. Consistency matters more than intensity for stress relief. References Burg, M.M., Schwartz, J.E., Kronish, I.M., Diaz, K.M., Alcantara, C. & Davidson, K.W. (2017, December 1).
