Addiction to screens can cause obesity

Addiction to cell phones and screens in general can not be good. This is something that can be understood in simple common sense. But more and more new research is emerging that warns that new technologies have negative consequences.

A new American study among more than 177,000 students suggests that insufficient sleep duration is associated with an unhealthy lifestyle among children and adolescents. Lack of sleep was associated with unhealthy eating habits, such as skipping breakfast. Approximately 40% of schoolchildren in the study slept less than recommended. The results of the study were published in the October 15 issue of the Journal of Clinical Sleep Medicine.

The American Academy of Sleep Medicine recommends that children from 6 to 12 years of age sleep from 9 to 12 hours regularly for a healthy life. On the other hand, adolescents from 13 to 18 years old should sleep from 8 to 10 hours.

Adequate sleep gives you a higher level of energy throughout the day. Children who report that they usually sleep less than nine hours a day, and adolescents who sleep less than eight hours a day are classified as not sleeping enough.

A larger proportion of men than women (42.3% versus 37.3%) and children compared with adolescents (42.1% versus 32.8%) reported insufficient sleep duration. Teens also had lower aerobics and are sleep related.

What happens when we sleep less than adequately?

When we sleep less than hours, there is an increase in all hormones that increase the feeling of hunger and appetite for foods rich in fats and sugars. One hour difference in sleep duration is able to introduce mechanisms to maintain weight.

There are two hormones associated with appetite that change with sleep hours, such as leptin, which suppresses hunger and ghrelin, which stimulates the appetite. The less hours of sleep, the less concentration of leptin, and ghrelin increases. As a result, the less we sleep, the more we want to eat. That is why if we sleep at least eight hours a day, we will be more likely to maintain adequate weight and fight obesity.

Proper sleep gives you higher levels of energy throughout the day. Therefore, children who sleep well may be more physically active during the day and, therefore, have a greater aerobic capacity.


Survey data from Colombia show that children aged 5 to 12 years have 67.7% of excess time in front of screens. Excessive time is more than two hours a day in front of these devices.

This figure increased to 76.6% among adolescents. Modern electronic media make it difficult to control the clock on the screen. All this has changed the habits and has become more noticeable in children and adolescents. The clock on the screen implies lack of sleep, which leads to deterioration of lifestyle and obesity.

Studies have shown that the brightness of screens at night is dangerous and degrades the performance. In addition, it causes a serious brain disorder, the luminosity deceives the brain, which interprets it as a prolonged twilight. These imbalances of sleep and graphics turn into a bad lifestyle. In addition to obesity in the short and medium term.

In the case of children, this leads to lower levels of physical activity, a progressive lack of muscle mass, a decrease in school efficiency, sleep disorders, problems of social interaction, aggressive behavior, consumption of alcohol and cigarettes, and attention deficit. An international study called Asthma and Allergies in Children's Phase 3, which included 37 countries, confirmed that there is a direct link between the increase in the number of hours spent on television and the body mass index (BMI).

Lack of sleep among children is a serious health problem. It is also underestimated in modern society and should be monitored and corrected. Control your watch in front of screens, stimulate sports, outdoor activities, foods in the fridge that are rich in protein nutrients, more fruits and vegetables, minimize sugary drinks and limit food consumption in the package.
