🌞 Sunlight & Circadian Rhythm - with Psychiatrist Dr Roopak Khara
🌞 Sunlight & Circadian Rhythm
In this video, you can discover how sunlight plays a vital role in regulating the body’s circadian rhythm — the internal clock that controls sleep, energy and overall health. This video explores how morning light suppresses melatonin to help you feel awake and alert, while reduced light in the evening allows melatonin to rise, preparing the body for rest. It also highlights how sunlight influences hormones, metabolism, immune function and body temperature. This video can help viewers understand why healthy natural light exposure is essential for sleep quality, emotional wellbeing and managing anxiety.
