Ensuring the resting space does not have a lot of light to help the cardiovascular system work properly, avoiding insulin resistance.
Sleep has a big impact on our health. A good night’s sleep can help you lose weight, reduce inflammation, and have a positive effect on the immune system. New research from Northwestern University (USA) shows that bedroom space can affect heart health and insulin resistance.
Accordingly, exposure to light during sleep increases the risk of heart disease, diabetes and metabolic syndrome. Light from windows, overhead lights, or spotlights can activate your autonomic nervous system, make your heart beat faster, and keep you awake.

“Typically, heart rate, along with other cardiovascular parameters, is lower at night and higher during the day,” explains study co-author Daniela Grimaldi.
Scientists found that people who slept in a well-lit room developed insulin resistance the next day. Insulin resistance occurs when cells don’t respond well to insulin so they can’t use glucose for energy efficiently.
That excess sugar remains in your blood, leading to an increased risk of cardiovascular disease and diabetes.
While not having all lights on while sleeping, exposure to artificial light at night is quite common for some people. If you live in a city, open blinds can let in ambient light from street lights, car headlights, etc. If you fall asleep with the TV on and the lights on, you’ll feel the effects. that negative.
Phyllis Zee, Dean of the Department of Sleep Medicine at Northwestern University Feinberg School of Medicine, shares some tips for avoiding the negative effects of ambient light.
First, don’t leave the lights on while you’re sleeping. If a completely dark room is a safety concern for some people, you’re better off using 1-2 nightlights to find your way when needed.
You should avoid blue light while sleeping. Warmer colors, like orange, red, and amber, are less stimulating to the brain. Put your phone away before going to bed. Using smartphones before bed can mess up your metabolism.
If you can’t avoid light while you sleep, consider purchasing a comfortable eye mask. Install blackout curtains if there is a light source outside the window at night.
