Experts explain how this practice affects rest and what it reveals about anxiety, fear, and personal routines.
many people They sleep with the light onwhether out of fear, habit or simply comfort. But, several studies show that keeping the bedroom lit alters the quality of sleep and can have effects on physical and emotional health.
Mainly what happens is that the brain need signs of darkness to activate melatonin, a hormone that regulates sleep cycles. When the light remains on, the body interprets that it is still daytime, which delay deep rest and generates a feeling of fatigue when waking up.

Fear, anxiety or habit? This is what psychology suggests
Sleep and psychology specialists agree that sleeping with a light on may be related to emotional factors. Fear of the dark, even in adults, continues to be one of the most common causes. Light generates a feeling of control and protection against thoughts or fears that arise in moments of silence and loneliness.
But the problem is not limited only to the psychological field. From a neurological point of view, keeping the environment illuminated reduces melatonin productionwhich shortens the phases of restful sleep. Continuous exposure to light, even with your eyes closed, tricks the brain into a state of mild alert.
In children and adolescents, the effects can be even more marked. Your circadian system is developing and needs total darkness to function properly. Sleeping with light can alter your rest schedules and cause concentration problems or irritability during the day.
Experts recommend keeping the room completely darkturn off screens and if necessary use a dim light or flashlight instead of a main lamp. These measures help restore the natural sleep cycle and improve the overall feeling of well-being.
