Sleeping with Lights On? Experts Warn of Hidden Health Risks
•Light exposure at night, even low levels, can disrupt the body's circadian rhythm and melatonin production.
•Sleeping with lights on can lead to poorer sleep quality, making sleep lighter and more fragmented.
•Nighttime light exposure is linked to hormonal disruption, affecting immune function, metabolism, and cell repair.
•Studies suggest a connection between sleeping with artificial light and increased risks of weight gain and metabolic imbalance.
•Blue light from screens and LEDs is particularly disruptive, strongly suppressing melatonin; warm, low-intensity light is less harmful but still not ideal.
