Light exposure

Light exposure refers to the amount of natural or artificial light that reaches your eyes. It influences your circadian rhythm—the internal clock that regulates sleep, wakefulness, and overall alertness. Proper exposure to natural light during the day helps maintain healthy sleep patterns, boosts mood, and supports overall well-being. Conversely, too much artificial light at night, especially from screens, can disrupt these patterns, leading to sleep difficulties and other health issues. Managing light exposure by getting sunlight during the day and reducing artificial light at night helps synchronize your internal clock for better health.
