Sleeping to turn on the lights, beware of the three types of diseases, find you!Elderly should pay special attention to

Some people like to sleep slowly in the dark environment, while others are accustomed to sleeping on the lights. As everyone knows, different sleep habits may have different impacts.

do you know? Keeping the bedroom dark when sleeping, not only helps to sleep well, but also reduces the risk of obesity and cancer. Studies have shown that those who are accustomed to light during sleep are more prevalence of obesity.

Recently, a new study published in the "Sleep" magazine shows that compared with adults who do not contact any light at night, those who use night lighting, or the elderly placed on TV, smartphones or tablets in the room in the room People (63 to 84 years old) may be more likely to obese, and it is more likely to suffer from hypertension and diabetes.

This is a real-world (non-experimental) study, which first joined the Chicago Heart Association Industrial Testing Project (CHA) from 1967-1973. This is a public health project and epidemiological research, which has conducted a detailed assessment of the risk factors of heart disease.

Around 2007 to 2010, researchers from Northwestern University of Northwest University conducted a separate "Study in Chicago Healthy Aging". Part of the original CHA research participants were included in the new project.

Participants in the study received detailed examinations and filled out their sleep diary every day. The study measured the light in the bedroom through the device worn on the wrist and tracked for 7 days.

Studies have found that among the 552 participants with an average age of 72 years, 410 (74%) and 128 (23%) participants have completed a 7 -day and 6 -day valid activity record, and the remaining 14 participants (2.5%) Complete 5 days of valid activity records.

Less than half of the participants sleep in a completely dark environment for 5 hours. Even the darkest 5 hours of the day (usually when sleeping at night) in the day, they will be exposed to certain light.

Compared with participants who are not exposed to light, from the perspective of sleep variables, the total sleep time and bed time of the night light exposure group are shorter, and the sleep efficiency is lower after sleep.

In addition, in variable analysis, it was found that participants in the night light exposure group were more prone to obesity (41% vs 27%, P <0.001), diabetes (18% vs 9.8%, P = 0.007) and hypertension (73% of 73%) (73%) VS 59%, P <0.001) and other health issues. The prevalence of hypertrophic alcohol not found between the two groups (59% VS 65%).

Studies have shown that under the light at night, it may increase the risk of the two most common chronic diseases in the world, that is, obesity and diabetes; at the same time, it may also increase the risk of hypertension in the main risk factors of cardiovascular disease.

"Whether using smartphones, starting TV overnight, or light pollution in big cities, we live in the environment of a large number of artificial light sources in 24 hours a day." School of Medicine) MINJEE KIM, assistant professor of neurosis, said, "The risk of the elderly with diabetes and cardiovascular diseases is higher, so we want to see if the incidence of these diseases is related to night light."

He further pointed out, "Even if there is only a small amount of light at night, it may be harmful to health."

Dr. Phyllis Zee, the author of the joint communication author and director of the Vanberg Sleep Medical Center, pointed out, "For people, avoiding or minimizing light when sleeping is very important."

Emerson Wickwire, a professor and director of the School of Medicine at the University of Maryland, pointed out that more and more scientific evidence shows that the importance of biological clocks and sleep on the human body to the overall health, especially for the health of the elderly, this study further confirmed this point.

How to reduce light and make sleep healthier?

The research team gives the following suggestions for how to minimize the light of the bedroom to minimize sleep quality and avoid these three major health issues:

Don't go to sleep on the light. If you need to turn on the lights for safety factors, you can turn on a light near the ground and weaker light.

Choose the right light and pay attention to the color of the light. Amber or red/orange light is less irritating to the brain. Do not use white or blue lights and place it away from the bed.

If the outdoor light cannot be controlled, to prevent the light of the bedroom from being too bright, you can use a hood or wearing an eye mask when you sleep.

Pay attention to the placement of the bed, do not let the outdoor light look on the face.
