Dick in his sleep? Investigation comes to scary results

Sleeping in the light, such as watching TV, is unhealthy. It is known. A study of women is now under investigation About artificial light when sleeping can actually lead to weight gain.

Obesity by sleeping in artificial light

Researchers at Research Triangle Park in North Carolina now have one in the journal JAMA Internal medicine published study with women found that artificial light can make you fat at night and even lead to obesity ("obesity").

Obesity is often the cause of chronic diseases

About 23 percent of women are obese, according to the World Health Organization (WHO). Obesity and obesity are crucial factors for chronic diseases such as diabetes and cancer. The American scientists not only see an unhealthy diet and lack of exercise causes obesity: “One nightly exposure to artificial light (ALAN – Artificial light at night) can contribute to the obesity pandemic. "

Years of research with surprising results: ALAN can make you fat!

Over a five-year period, researchers from the National Institute of Health investigated approx. 44,000 women aged 35 to 74 years. Over the past two years, they have evaluated the data: Results show that watching TV and artificial light while sleeping with women is associated with an increased risk of weight gain and obesity.

Weight gain by five kg

Compared to the participants in completely darkened rooms, those who slept with ALAN took five kg in weight and up to ten percent of the BMI value as well. Previous animal studies also show that nocturnal exposure can have a negative effect on the rhythm at night.

Disruption of day-night rhythm

The so-called "clock genes" were suppressed in the study by permanent light irradiation and disrupted the "round-the-clock rhythm". As a result, rodents also changed feeding behavior – the result was an increase in weight.

Consequences: stress hormones and more time to eat

Also ALAN from the environment, such as street lights and neon signs, led to suppression of the sleep hormone "melatonin". Eg. The stress hormone "glucocorticoids" were produced for this purpose.

"Shorter sleep also adds more awake time, giving more time to eat or increase energy," said Dale P. Sandler.

Obesity and obesity are prevented by darkness

Therefore, to prevent overweight and obesity, women should adhere to healthy living habits, such as a vitamin-rich diet, as well as being physically active. These components can lead to a low level of stress.

The TV and night light as well as the smartphone must be displayed before going to bed. A sleep as quiet as possible thanks to a dark room is the best prerequisite for starting the next day in recovery and fitness.

Why not sleep on the right side anymore

Not only the sleep duration, but also the sleeping position is relevant for a healthy life. This has now been proven by experts. Therefore, it is better to lie on the left side of the body: healthy through proper sleep.
