We often hear that adults need eight hours of sleep per night, but the ideal amount varies depending on age and individual factors like health, activity level and genetics. Getting the right amount of sleep is critical for cognition, immune function and overall well‑being. Let’s explore how much sleep you really need.
Recommended Sleep Durations
Organizations such as the National Sleep Foundation and American Academy of Sleep Medicine publish guidelines for recommended sleep duration. These ranges are intended for healthy individuals with typical lifestyles.
| Age Group | Recommended Hours |
|---|---|
| Newborns (0–3 months) | 14–17 hours |
| Infants (4–11 months) | 12–15 hours |
| Toddlers (1–2 years) | 11–14 hours |
| Preschoolers (3–5 years) | 10–13 hours |
| School-age children (6–13 years) | 9–11 hours |
| Teenagers (14–17 years) | 8–10 hours |
| Adults (18–64 years) | 7–9 hours |
| Older adults (65+ years) | 7–8 hours |
Factors That Influence Sleep Needs
While these guidelines provide a useful starting point, you may need more or less sleep depending on various factors:
- Health conditions: Illness, chronic pain or sleep disorders can increase the need for restorative sleep.
- Physical activity: Athletes and those who engage in strenuous exercise may need additional sleep for recovery.
- Stress levels: High stress or demanding mental work can leave you feeling fatigued and requiring more rest.
- Genetics: Some individuals naturally thrive on less sleep, while others feel their best with more.
