Light and sleep

The sleep Foundation article examines how light exposure affects sleep quality and its subsequent impact on brain health and cognitive performance. It explains that light exposure, particularly blue light from electronic devices, can suppress melatonin production, a hormone that regulates sleep-wake cycles, leading to difficulties in falling asleep and maintaining restful sleep. Disruptions in sleep can impair cognitive functions such as memory consolidation, attention, and decision-making. To enhance sleep quality and support brain health, the article recommends minimizing exposure to screens before bedtime, using dim lighting in the evening, and creating a dark sleeping environment. These suggestions are based on scientific research highlighting the importance of light management in maintaining healthy sleep patterns and optimal cognitive function.
