“Women who sleep with a light or television on in the room are more likely to gain weight, as artificial light at night (ALAN) affects the body's metabolism.”

Women who sleep with a light or television on are significantly more likely to gain weight, with studies showing they are about 17% more likely to gain at least 5 kg (≈11 lb). Research links exposure to artificial light at night to hormonal and metabolic disruptions that raise obesity risk.
