Question

Jennifer P asked:

Do we sleep better in blocks of four hours?

Answer

We asked Professor Russell Foster:

No. It depends on the individual but most of the time itís an eight hour block. Sometimes you can separate it in the middle with a slight waking up phase and then you go back to sleep again. On the whole, no.

Jennifer P asked the Naked Scientists: I'm writing from cold snowy Montreal I was wondering if it's true that we have to sleep in blocks of 4 hours in order to get a good night sleep. in other words 9 hours you would wake up sleepy but 8 hours would be just right. Looking forward to the next Podcast Thanks a bunch Keep up the great work What do you think? Jennifer P, Sun, 15th Jun 2008
