Sleeping With Lights On Can Cause Serious Health Issues, Suggests Research!

Most people go to bed at night without turning off the lights. Some people lit the night lamp. A team of American researchers claims that even the slightest light at bedtime can highly increase the risk of obesity, high blood pressure, and diabetes in the elderly.

Researchers say that exposure to light during sleep makes it difficult for your brain to achieve deep sleep. The more shallow or light sleep you get at night, the more negatively your brain’s oscillations (activities) that allow you to go to the deeper stages of sleep are negatively affected.

A study has been conducted on the effect of light on the sleep of the elderly aged 63 to 84 years by a team of scientists from Northwestern University in the United States. The study was recently published in the famous science magazine Slip. A total of 552 people took part in the study.

Scientists divided the participants into two sections and conducted experiments. One group of people slept in complete darkness for at least 5 hours a day without any light. Others have little time to sleep, but the lights are on.

The result of the survey shows that those who have completely turned off the light are less likely to be overweight or obese. There is less risk of hypertension or high blood pressure and diabetes. However, researchers are not sure exactly why this is happening.

Also, if you need to go to the bathroom at night or get up for some other work, it is a bit inconvenient for the elderly to turn off the lights completely. Therefore, scientists say that more detailed research is needed on the whole issue.
