The results of a new study published in the scientific journal JAMA Internal Medicine revealed that women sleeping in a room with lighting, whether from the TV or lamp, may contribute to their weight gain.

The researchers behind the study indicated that the experiment they conducted found that a room with any kind of lighting was associated with a women’s weight gain of about five kilograms in about five years.

The researchers reported that this matter over the years puts women at risk of developing overweight and obesity as well, which in turn increases the risk of many different diseases such as heart disease.

To reach these results, the researchers targeted 43,722 women, their ages ranged between 35-74 years, and they were divided into groups based on whether or not there was lighting in the room.

The researchers observed the following results, an increase in the weight of women who were in lighted rooms by about 5 kg during the five years, as mentioned earlier.

The researchers emphasized that despite the presence of obstacles in this study, it gives us an indication of the need to sleep in dark rooms during the night hours, in order not to interfere with the sleep process that the body is going through.
