Study Reveals How Much Sleep You Need At Different Ages

A new study suggests that adults aged 18–60 should aim for at least 7 hours of sleep per day. The Centers for Disease Control and Prevention (CDC) note that recommended sleep durations vary significantly by age group.

The CDC’s sleep guidelines are as follows: Newborns (0-3 months): 14-17 hours; infants (4-12 months): 12-16 hours; toddlers (1-2 years): 11-14 hours; preschoolers (3-5 years): 10-13 hours; school-age children (6-12 years): 9-12 hours.

Teenagers (13-17 years): 8-10 hours; adults (18-60 years): 7 hours or more; older adults (61-64 years): 7-9 hours; adults 65 years and older: 7-8 hours. While age significantly influences sleep needs, other factors also affect the amount of rest required for optimal functioning.

Factors affecting sleep quality include:
* Frequent interruptions can compromise overall sleep quality.
* Previous sleep deprivation: increases the body’s need for recovery sleep.
* Pregnancy: Hormonal changes and physical discomfort can reduce sleep quality.
* Aging: Older adults often experience lighter sleep, longer time to fall asleep, shorter sleep duration, and frequent nighttime awakenings, despite needing similar amounts of sleep as younger adults.

Sleep strengthens the immune system, aiding in the fight against infections and illnesses. It also influences hormones that control hunger and fullness, affecting weight management—adequate sleep supports a healthy weight. Additionally, sleep regulates emotions and reduces stress hormones, contributing to better mental well-being.
