Regular exercise and a healthy diet is known as a way to maintain a healthy weight is normal, but a recent study says the new solution to fight obesity in children, with sleep.
Through research conducted by scientists at Northwestern University, UK, found that kids who get enough sleep will have a body mass index (BMI) and a lower risk of obesity in the next five years will be reduced, compared to children who lack sleep.
Add time to sleep at night will reduce the likelihood of obesity 30-36% in children and 34% in children aged pre-teen. That is the conclusion of researchers who are also published in the journal Child Development.
The researchers conducted a nationwide data collection on 2,281 children aged 3 to 12 years. Parents of these children are given a kind of daily schedule to record information such as time began to sleep, how long, and when I wake up. The recording is done for five consecutive years.
Of the daily schedule, known to the children who lack sleep, get used to staying up late, or get up too early, after five years tend to be obese. Research also shows that bed late at night have a great impact on obesity, especially in children aged 3 to 8 years. While the impact of obesity due to get up too early is more common in children aged 8 to 13 years.
The National Sleep Foundation, UK, recommends that children aged 5 to 12 years old should sleep for 10 to 11 hours each night, while the older children get enough sleep 8 to 9 hours.
Lack of sleep not only affects the child’s weight, but also result in other things, such as reduced academic ability, alcoholism, weak immune system, hypertension, diabetes, and heart disease.
The research team did not know the link between sleep and obesity in children, but they suspect the child’s lack of sleep causes fatigue that ultimately did not have the energy to exercise. In addition, waking up early will make children eat more. Lack of sleep is also known to disrupt hormones that affect metabolism and hunger.
Although not known with certainty the link between sleep with obesity, but the researchers warn that parents observe their children bedtime.
