Sleeping with Lights On: Harmful or Healthy? Experts Reveal Impact on Sleep & Health

• Sleeping with lights on, even dim ones, disrupts the body's internal clock and melatonin production.
• Light exposure at night can lead to poor sleep quality, making sleep lighter and more fragmented.
• Hormonal disruption from reduced melatonin impacts immunity, metabolism, and cell repair.
• Studies link sleeping in artificial light to increased risk of weight gain and metabolic imbalances.
• Blue light is particularly disruptive; warm, dim night lights are recommended if complete darkness isn't possible.
