How many hours of sleep do kindergarteners need?

How many hours of sleep do kindergarteners need – Like many parents, Araya depends on the signs of her children – drowsiness, irritability, difficulty concentrating – to determine how much sleep they need, more than counting the right amount. Both Adrian and Christina are included in the latest guidelines.

How many hours of sleep do kindergarteners need?

For about a decade, the child sleep community has recommended that children aged three to five years need 11 to 13 hours, children aged five to 10 years need 10 to 11 hours, and adolescents 10 to 17 years need eight and a half years. up to nine and a half hours of sleep every night.

But three studies published over the past year have led to new, and sometimes conflicting, information. The first, conducted at Brigham Young University in Utah, claims that less is actually more in terms of total neonates and adolescents. BYU scientists analyzed nearly 2,000 school children, and found that children with academic achievement lacked sleep when they grew older. For children aged 10 years, optimal sleep time is nine to nine and a half hours; for children 12 years old, it’s eight to eight and a half hours; and for 16-year-olds, it’s only seven hours.

Study co-author Mark Showalter speculates that extra hours of waking time are spent studying rather than sleeping, thus increasing grades. “Most of our students at BYU realize that sleeping nine hours a night is not what top students do,” he observed.

A further study in the journal Pediatrics questions the validity of sleep guidelines in general. This paper (“Never Enough Sleep: A Brief History of Sleep Recommendations for Children”) surveyed sleep literature from the 19th century to 2009. It was found that children’s sleep duration had steadily decreased by 0.73 minutes a year – children modern-day children lack sleep compared to our ancestors did it – and that the recommended number of blindfolds is always around 37 minutes more than children actually get, whether that year was 1897 or 1997. It was also found that most sleep recommendations were based on substandard experiments, and that “there is almost no empirical evidence for optimal sleep duration for children. “

Does losing an hour of sleep make a difference?

Add to the pile of recent studies from McGill University in Montreal that confirm something that most parents already know: When children ages seven to 11 sleep less than one hour than usual, they show increased behavioral problems, including irritability, frustration and difficulty paying attention. Those who sleep extra one hour better behave.

Penny Corkum, a child sleep researcher in Halifax, agrees that taking even one hour of sleep from a healthy child will cause instant changes in mood, attention and function. He said that 10 hours in the dream world was optimal, but some children might need more. “It is important to remember that this is only a guideline. They are not definitive and need to be interpreted individually.”

Corkum was most interested in historical studies which found that sleep had fallen dramatically over the past 100 years. “Biology does not allow for such adaptations.” Children lose sleep faster than their bodies can evolve to work well with lack of sleep, he said.

So, even though there is evidence that older children who lack sleep may get better grades, it seems that reducing sleep time to increase your child’s value makes no sense.
