Night Exercise's Impact on Health
Any research that say night exercise is bad
The research on the impact of night exercise on health presents mixed findings. Here's a summary of relevant conclusions from various studies:
-
Positive Impact of Night Exercise on Sleep Quality: Some studies suggest that exercise, including night-time activities such as jogging and evening walks, can positively impact sleep quality. Light and moderate exercise early in the evening are particularly beneficial, improving ease of falling asleep, deepness of sleep, and morning alertness (Vuori et al., 1988).
-
Complex Interrelation Between Physical Exercise and Sleep Quality: Research indicates a complex relationship between physical exercise and sleep quality. While physical activity can enhance sleep, the specific effects of acute exercise level on sleep quality, especially when conducted at night, require further investigation (Liu et al., 2019).
-
Impact on Circadian Rhythms and Mental Health: Shifting the late timing of 'night owls' through interventions including exercise can positively impact mental health and performance, suggesting that well-timed night exercise may be beneficial (Facer-Childs et al., 2019).
-
Vigorous Late-Night Exercise and Sleep Quality: Contrary to common beliefs, one study found that vigorous late-night exercise does not disturb sleep quality, although it may affect cardiac autonomic control during the initial sleeping hours (Myllymäki et al., 2011).
-
Physical Activity Improving Sleep Among Inactive Insomniacs: Increased physical activity to recommended public health guidelines can significantly reduce insomnia symptom severity and improve mood among inactive adults with insomnia (Hartescu et al., 2015).
In conclusion,
while there is no definitive evidence suggesting that night exercise is universally bad for health, the relationship between physical activity and sleep quality appears to be complex and variable depending on factors such as the intensity and timing of the exercise. Moderate exercise, especially early in the evening, seems to have predominantly positive effects on sleep quality. However, vigorous late-night exercise might not disturb sleep quality but could affect cardiac autonomic control during early sleep hours. Regular physical activity, including at night, can improve sleep and mood outcomes, particularly in individuals with insomnia.
