One of the common questions asked by many people regarding sleep is how many hours of sleep do you actually need?

If you do a lot of physical and mental labor you need to sleep more than the person who works on average job. If you are not well, for instance, you have fever; you need to sleep more than a normal person because sleeping more helps you to recover faster. In order to find out how many hours you need to sleep, let’s look at the following data:
[list]Newborns (0-3 months) sleep just few hours at a time, and need 16-18 hours of sleep.[/list]
[list]Infants (4-12 months) need 12-16 hours of sleep and their body understand the night time and day time sleeping[/list]
[list]Toddlers (1-2 years) need 11-14 hours of sleep, they sleep well at night and take naps in the day.[/list]

[list]Teens (13-18) need 8-10 hours of sleep; they tend to stay up until late hours[/list]
