Rafael Santana Miranda, a doctor at the Sleep Disorders Clinic of the Faculty of Medicine (FM) of the UNAM, at the General Hospital of Mexico, said that holidays are a special and necessary period. At some point, we have all heard "Your child grew up on vacation", and it is not that it is a myth, it is true because they sleep more, they do not have to get up early, and then it causes the growth hormone to be released.

We know that sleep is fundamental for humanity, but we live in a restricted society of sleep: adults sleep less and less and our children do not do the hours they require according to their age and this is reflected in their growth and development, he alerted.

The children's sleep hours must be respected, it is not bad that they sleep more time later they will adapt again to the school schedule, for this reason, it is also necessary to watch that the children go to bed early because no medication or therapy achieves the effects that sleeping has. Not resting enough is the basis of metabolic, cardiovascular, low performance, and lack of growth disorders.

The doctor stressed that childhood obesity has to do directly with lack of sleep: when you sleep a little and poorly activates the appetite area in the brain, with a predilection for carbohydrates.

On the other hand, adolescents tend to have a disturbed circadian cycle, since they have a delayed phase of sleep because they go to bed very late, sometimes in the early hours of the morning and they steal hours of rest by being attentive to the cell phone.

It should be noted that as one grows there are different changes and needs so newborns sleep between 16 and 18 hours, children of school age (between 6 and 12 years) must sleep 10 hours, teenagers nine and adults eight hours.
