@howyourhouseworks.au: Stop falling asleep with the TV on 📺😴 Your eyelids let light through, and in one Northwestern study of 20 healthy adults, a single night under room lights kept their heart rate higher all night and raised next-morning insulin resistance by about 15%, even though they didn't wake more or feel any different. A separate study of 43,722 women linked sleeping with a TV or light on to being more likely to put on 5 kg or more over about 6 years. Set a sleep timer for 30 minutes and turn the lights off; if you need noise, use a speaker with no screen, and if you truly need a light, keep it dim, amber and low. The lead researcher's test: if you can see things really well, it's too light. #sleep #sleeptips #health #bedroom #howthingswork
