Sleep Needs Throughout Life

Sleep requirements change dramatically as we age. Understanding these changes helps you optimize your sleep schedule and improve your overall well-being. Our sleep calculator takes these age-specific needs into account.

Infants (0-5 years)

11-14 hours
7-9 cycles

Rapid brain development requires extensive sleep for growth and learning.

Kids (6-13 years)

9-11 hours
6-7 cycles

School-age children need consistent sleep for cognitive development and physical growth.

Teens (14-17 years)

8-10 hours
5-6 cycles

Hormonal changes shift sleep patterns, making teens naturally prefer later bedtimes.

Adults (18-64 years)

7-9 hours
4-6 cycles

Working adults need balanced sleep for productivity, health, and emotional well-being.

Seniors (65+ years)

7-8 hours
4-5 cycles

Older adults experience changes in sleep architecture but still need quality rest.
