Artificial light exposure, especially before bedtime, can disrupt melatonin production and affect sleep quality. Studies indicate that light from screens and bright bulbs can interfere with the body's natural sleep signals. Even moderate ambient light during sleep can alter physiological processes, such as heart rate and glucose regulation. To improve sleep conditions, experts recommend reducing light intensity in the evening and limiting screen use. Natural light exposure during the day helps synchronize the biological clock, while maintaining consistent sleep schedules supports better rest.
