How sleeping with lights on — even if they’re dim — may affect your sleep quality
Sleeping with dim lights, such as fairy lights, can disrupt sleep quality, according to Dr. Pooja T, a Senior Specialist Pulmonologist at Aster RV Hospital, Bangalore. Even low-level ambient light can suppress melatonin production, delaying the body's transition into restorative sleep modes and affecting the circadian rhythm. This disruption may lead to waking up unrefreshed and feeling more tired during the day.
