Hours of sleep depending on age

In particular, in this study the range of hours of sleep generally recommended so far has been adjusted, dividing the population into nine age groups:

• infants (0 to 3 months): 14-17 hours of sleep per day (before: 12-18 hours);
• children from 4 to 11 months: 12-15 hours of sleep per day (before: 14-15 hours);
• children from 1 to 2 years: 11-14 hours of sleep per day (before: 12-14 hours);
• children from 3 to 5 years: 10-13 hours of sleep per day (before: 10-11 hours);
• children from 6 to 13 years: 9-11 hours of sleep per day (before: 10-11 hours);
• adolescents (14 to 17 years): 8-10 hours of sleep per day (previously: 8,5-9,5 hours);
• adults from 18 to 25 years: 7-9 hours of sleep per day (age class not considered before);
• adults from 26 to 64 years: 7-9 hours of sleep per day (unchanged range);
• elderly (over 65 years): 7-8 hours of sleep per day (age class not considered before).

The recommendations for adults have not changed. Instead, two previously not considered bands have been added: that between 18 and 25 years and that of the over 65s.

As for babies and children, the daily sleep hours have all been tweaked. For example, the need for sleep for children aged 3-5 increases, while the need for adolescents between 14 and 17 years is concentrated. (Take the quiz: do you know all about the baby's sleep?)
