Sleep Needs by Age: The Complete Guide

Von SleepCalculatorCo Forschungsteam Zuletzt aktualisiert: June 27, 2026

Key Takeaways for All Ages

  • Infants need up to 17 hours of sleep per day.
  • Adults require 7-9 hours (5-6 cycles) for optimal cognitive function.
  • Seniors still need 7-8 hours, but their deep sleep decreases.

As we age, our sleep architecture changes dramatically. Understanding your specific age group's needs is crucial for long-term health.

Infants and Toddlers

During the first years of life, the brain is developing at an unprecedented rate, requiring massive amounts of sleep.

Adults (18-64)

For adults, consistency is more important than total duration. Aiming for 5 complete 90-minute cycles is the standard.

Quick Reference

Teenagers: 8-10 hours. Adults: 7-9 hours. Seniors: 7-8 hours.

Seniors (65+)

Older adults often experience lighter, more fragmented sleep, but their overall biological need remains similar to younger adults.
