. Sleep needs vary by age group, with infants, children, and teenagers requiring more sleep to support growth and development. For example, teenagers need about 8 to 10 hours, while adults 18 and older should get at least 7 hours
. Some individuals may require slightly more or less sleep depending on genetics, health status, and lifestyle, but 7 hours is the recommended minimum for most healthy adults
. In summary:
- Adults (18-64 years): 7 to 9 hours per night
- Older adults (65+ years): 7 to 8 hours per night
- Teenagers (14-17 years): 8 to 10 hours per night
- Children and infants require progressively more sleep depending on age
If you have concerns about your sleep quality or duration, consulting a healthcare provider or sleep specialist is advisable
. Thus, aiming for at least 7 hours of good-quality sleep nightly is the best general guideline for adults to maintain health and well-being.
