Sleep deprivation increases BP, diabetes risk
Consequences of too little, too much or endless nights of broken sleep are very serious, new research has suggested.
Most experts believe that between six and eight hours is the right amount for an adult. Teenagers need about nine hours a night and young babies up to 16 hours a day.
Researchers at the University of Pennsylvania studied nearly 140,000 people and found adults on fewer than six hours a night were up to 36 per cent more likely to suffer a heart attack and 22 per cent more at risk of a stroke than those who got a good night`s rest, the Daily Express reported.
Another Japanese study found those regularly sleeping fewer than six hours a night raised their risk of a breast tumour by more than 60 per cent.
