Nearly half of teenage girls in Britain struggle to stay attentive in school as they do not get enough sleep, reveals a new survey.
According to the study by the School and Students Health Education Unit, 63 per cent of 12 to 13-year-olds say that they are getting enough sleep for their studies but the figure goes down, as they get older, the Scotsman reported.
Almost half (48 percent) of 14 to 15-year-old girls say they do not get enough sleep to concentrate on their schoolwork, as compared to two-fifths (41 per cent) of 14 to 15-year-old boys, who say the same.
It was also revealed that the proportion of youngsters getting eight hours or more of sleep at night drops with age.
Four-fifths of 12 to 13-year-olds got this amount of sleep, compared to 61 per cent of 14 to 15-year-old girls and 66 per cent of boys of this age.
The study is based on the data gathered by taking into consideration the point of view of 83,000 children in 2010.
And almost half (48 per cent) of the youngsters questioned said they do not normally get enough sleep for their health.
