Light and Exercise Regulate Sleep
- Natural light exposure and physical activity regulate our circadian rhythm which promotes healthy sleep.
- Lack of outdoor light and exercise leads to poorer sleep and can contribute to seasonal affective disorder.
Cortisol Disrupts Sleep

- Modern stress triggers this evolutionary alert system, interfering with sleep despite lack of physical threat.
