Addiction to screens can cause obesity

Dependence on mobile phones and screens in general can not be good. It's something that one can guess in simple common sense. More and more studies are emerging that warn that new technologies have negative consequences.

A new American study, conducted among more than 177,000 students, suggests that insufficient sleep duration is associated with an unhealthy lifestyle profile in children and adolescents. Insufficient sleep time was associated with unhealthy eating habits such as skipping breakfast. Approximately 40% of school children 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 children between the ages of 6 and 12 regularly burning a healthy life between nine and twelve hours. On the other hand, adolescents from 13 to 18 years should sleep between 8 and 10 hours.

Adequate sleep produces higher daily energy. Children who reported sleeping less than nine hours a day and teenagers sleeping less than eight hours a day were classified as sleep deprivation.

Higher proportions of men than women (42.3% vs. 37.3%) and children compared to adolescents (42.1% vs. 32.8%) reported insufficient sleep duration. Adolescents also had a lower aerobic condition and were associated with sleep.

What happens when we sleep less than adequate?

When we sleep less than an hour, there is an increase in all the hormones that increase the sense of hunger and the appetite rich in fats and sugars. The one hour difference in the length of sleep is able to put in place mechanisms to maintain weight.

There are two sleep-related hormones that change with sleep, such as leptin, which prevents the feeling of hunger and ghrelin that stimulates appetite. The less hours of sleep, the less the concentration of leptin and ghrelin increases. The result is that the fewer we sleep, the more we want to eat. Therefore, if we sleep at least eight hours a day, we will have a greater chance of maintaining adequate weight and fighting obesity.

A good dream creates a higher level of energy during the day. Therefore, children who are sleeping well may be more physically active during the day and therefore have greater aerobic capacity.


Survey data in Colombia shows that children aged 5 to 12 have 67.7% of the time over screens. The time is too long two hours ahead of these devices.

This number increased to 76.6% in adolescents. Modern electronic media make it difficult to control the clock on the screen. It all changed habits and is more noticeable in children and adolescents. Clocks on the screen indicate a lack of sleep, leading to a worse lifestyle and obesity.

Studies have shown that screen brightness at night is dangerous and worsens the view. In addition, it creates a serious disorder to the brain, the light deceives the brain, interpreting it as an extended nightfall. These sleep imbalances and schedules are reflected in poor lifestyle. In addition to obesity in the short and medium term.

Children experience lower physical activities, progressive muscle mass deficiency, lower school performance, sleep disorders, social interaction problems, aggressive behavior, alcohol and cigarette consumption, and lack of attention. The international study, called asthma and allergy in the third stage of childhood, which included 37 countries, confirmed a direct relationship between the increase in the number of hours spent watching television and the body mass index (BMI).

Insufficient sleep duration in children is a serious health problem. This is also underestimated in today's society, and it is something that should be monitored and corrected. Control the clock in front of the screens, stimulate sports, outdoor activities, leave products rich in protein, more fruits and vegetables in the fridge, minimize sweet drinks and reduce the consumption of packaging.
