[Sianel Iechyd/Adroddiad Cynhwysfawr]Sleeping with the windows open and falling asleep at night, seems common but carries risks. People exposed to outdoor light while sleeping at night can raise blood sugar and heart rate, increasing the risk of diabetes, the study noted. The study was published in the medical journal Diabetologia.
Sleeping in a room exposed to outdoor artificial light at night could increase the risk of diabetes, according to a study of nearly 100,000 Chinese adults, CNN reported. People who live in areas with severe nighttime light pollution in China are about 28 percent more likely to develop diabetes than those who live in areas with the least pollution.
Phyllis Zee, director of the Center for Circadian Rhythm and Sleep Medicine at Northwestern University School of Medicine in Chicago, said the study confirms previous research on the potential adverse effects of nighttime light on metabolic function and diabetes risk.
Effects of night light on health
Studies have shown links between artificial light at night and weight gain and obesity, metabolic dysfunction, insulin secretion and the development of diabetes, and cardiovascular risk factors. Gee and her team previously published a study examining the effects of light on sleep in healthy adults in their 20s. In a sleep lab experiment, a night of sleep with dim lights (like a TV with the sound off) increased blood sugar and heart rate.
Previous research has also shown that a high heart rate at night is a risk factor for future heart disease and early death, while a higher blood sugar index is a sign of insulin resistance, which can lead to type 2 diabetes in eventually. Gareth Nye, senior lecturer in physiology at the University of Chester in the UK, also said that healthy sleep is very important to prevent the development of diabetes.
The method of blocking light given by experts to reduce light pollution at night
Gee suggests trying to reduce the amount of light at night, such as by placing the bed away from the window and drawing the curtains to block out the light. If you still feel the light, you can try wearing an eye mask to protect your eyes. In addition, pay attention to the light in the bedroom and prohibit the use of any blue light, such as the light emitted by electronic devices such as televisions, smartphones, tablets and laptops, “because blue light is the visible light most irritating”.
If the lights must be on for safety reasons, she says it is possible to change the color of the lights, choosing ones with a red or brown tint, and recommends dimming night lights and lay flat with the floor to meditate rather than Hold. close to your eyes at bed level.
