Common bedroom mistake could be quietly taking a toll on your health, experts say, tell me about this news in (https://www.foxnews.com/health/common-bedroom-mistake-quietly-taking-toll-your-health-experts-say)

The article discusses a common bedroom mistake: sleeping with artificial light on, such as nightlights, televisions, or light leaking in from outside.According to a study from Tulane University cited in the report, nighttime light exposure exceeding just 3 lux (roughly equivalent to the brightness of moonlight) was associated with an increased risk of serious cardiovascular problems, including heart failure, atrial fibrillation, heart attack, stroke, and cardiovascular death.Key points highlighted by experts in the article include:

• Circadian rhythm disruption: Light entering the eyes suppresses the brain’s production of melatonin, the hormone that regulates sleep timing, which leads to poorer sleep quality and prevents proper brain and body restoration.
• Health consequences: Chronic light exposure during sleep disrupts glucose metabolism, elevates heart rate, reduces heart rate variability, and may increase long-term risks for hypertension, type 2 diabetes, obesity, and mood disorders.
• The most disruptive light: Blue-wavelength light from screens (phones, tablets, televisions) is the most damaging because the retinas are most sensitive to it, leading to strong melatonin suppression. Warm, dim, red- or amber-toned light causes far less disruption.
• Expert recommendations:
  • Turn off harsh overhead lighting 1 to 2 hours prior to sleeping.
  • Avoid all digital screens at least one hour before bed.
  • If a nightlight is necessary, place it low to the ground and use dim, warm-toned bulbs (red, orange, or amber).
  • Use blackout curtains or window treatments to block streetlights, or wear a sleep eye mask.
