The benefits of exercise for mental health are well known, but when you are physically active may play a role in how it affects you. Greater awareness of how exercising at different times of day can change your mood, anxiety levels, clarity of thinking, and how well you sleep, you can choose when to be active to help you reach particular goals.

Why Time of Day Matters to Your Mental Health

A complex interplay of psychological, social, and biological factors influences your mental health. One key influence on your emotions and sense of well-being is the circadian rhythm, your body’s 24-hour internal clock.

This biological clock regulates when you feel more tired or alert and also influences your body to produce hormones and neurotransmitters that affect mood, stress, and overall well-being.1
