In addition to age, other factors may affect how many hours of sleep you need. For example:
- Pregnancy. Changes in a woman's body during pregnancy can increase the need for sleep.
- Aging. Older adults need about the same amount of sleep as younger adults. As you get older, however, your sleeping patterns may change. Older adults tend to sleep more lightly and awaken more frequently during the night than do younger adults. This may create a need for or tendency toward daytime napping.
- Previous sleep deprivation. If you're sleep deprived, the amount of sleep you need increases.
- Sleep quality. If your sleep is frequently interrupted or cut short, you're not getting quality sleep — and the quality of your sleep is just as important as the quantity.
If you experience frequent daytime sleepiness, even after increasing the amount of quality sleep you get, consult your doctor. He or she may be able to identify any underlying causes — and help you get a better night's sleep.
