+ Babies do it for up to 8 hours a day. Sleep. No one can live without it. But how much do we really need?
Scientists say that we all need 8 hours’s sleep every night .They find that, on average, adults sleep for 7 hours a night, with 32% sleeping less than 6 hours .They also say that the idea that we need less sleep as we get older is completely untrue. Professor Jim Horne of Southborough University studied a group of people who could spend as many hours as they wanted in bed ; after 10 hours they didn’t find it any easy to get up in the morning.
*Questions:
1.How many hours a day do babies sleep?
2.How many hours a day should we sleep?
3.How many hours a day do most people sleep?
4.What percentage of people sleep less than 6 hours a day?
5. Can people get up early in the morning after 10 hours’ sleep?
