What is the affect of napping on the body?

Chris Idzikowski (Director of the Edinburgh Sleep Centre) gives expert video advice on: What happens to my brain when I sleep?; What happens to my muscles when i sleep?; What happens to my breathing when I sleep? and more...

Generally can be quite beneficial and one of the things, one of the mysteries about sleep is we don't know what causes us to feel refreshed after sleeping. Good nappers, people who can take a ten, fifteen minute nap, can feel as refreshed after that nap as they can do after nighttime sleep. So we don't know what's going on there. I'd have the general rule of thumb of small amounts of sleep will invariably help mental performance and would say any sleep anytime is worth while getting. Where I wouldn't say that is if somebody has <a href="http://www.videojug.com/interview/hypersomnia-2">hypersomnia</a> or is having problems with nighttime sleep and they were trying to improve their night time sleep. Then what one would do is avoid the daytime sleep to try to increase the pressure for sleep that following night.
