“The boys who slept eight hours a day would also have 1.8 kg more lean(bone and muscle) mass compared to the boys who slept 10 hours,but that’s only a 1.4 percent increase,compared to the 9 percent increase seen in body fat,”said lead researcher from the Department of Human Nutrition,Dr.Paula Skidmore.
“Our results suggest that for older teenage boys,making sure that they get enough sleep may help to maintain a healthier body.It seems to be that,within reason,the more sleep the better for boys,”Skidmore said in a statement Thursday.
“It was unexpected that we did not find the same result in girls,who may actually be more aware of their diet and more in tune with a healthier lifestyle.”
The researchers ruled out the effects of food choice and the number of screens,such as televisions,games and consoles,which the teenagers had in their bedrooms.
