For healthy sleeping ,the amount of sleep need depends on different factors. One of these factor is according to age. The research shows that people who sleep so little over many nights don’t perform as well on complex mental tasks as do people who get closer to seven hours of sleep a night.
Here is general sleeping time for different age groups
| Age group | Recommended amount of sleep |
| Infants | 9-10 hours at night, plus 3 or more hours of naps |
| Toddlers | 9-10 hours at night, plus 2-3 hours of naps |
| School-age children | 9-11 hours |
| Adults | 7-8 hours |
Beside these other factors also depends the amount of sleep needed. Some others are:
- Changes in a woman’s body during early pregnancy can increase the need for sleep.
- Older adults need about the same amount of sleep as younger adults. As getting older,the sleeping patterns might change. Older adults tend to sleep more lightly and for shorter time the younger adults. This might need for spending more time in bed to get enough sleep, or need daytime napping.
- Previous sleep deprivation.If you’re sleep deprived, the amount of sleep you need increases.
- Sleep quality.If the sleep is frequently interrupted then the quality of sleep is not good.. The quality of your sleep is important as the quantiy of sleep also.
