Quick takeaways

The Impact of Light Exposure on Sleep

Light exposure, particularly bright light from sunlight, plays a crucial role in regulating sleep and wakefulness. The neurons in the back of the eye are activated by bright light, sending signals to the brain's hypothalamus, which controls sleep, hormones, immune function, appetite, and mood. To optimize sleep, it is recommended to get bright light exposure, ideally from sunlight, in the morning for about 5-20 minutes. If sunlight is not available, bright artificial lights can be used. In the evening, it is advised to dim lights to promote the natural decrease in body temperature and melatonin release, which helps induce sleep.
