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.
