How much should children sweat, step, sleep and sit? The new rules.

I read an article this week in which researchers in Glasgow have helped formulate "the perfect recipe for a healthy day" for children.

The guidance covers 24 hours and includes how much time young people should spend sleeping, exercising and watching screens.

Nine to 11 hours of uninterrupted slumber is recommended for children aged five to 13, while those aged 14 to 17 should sleep for eight to ten hours at night.

Exercising at a moderate or vigorous pace should take up an hour every day overall, according to the guidelines, but there should also be several more hours of light activity.

Time in front of the TV, computer or i-pad is limited to two hours or less a day, by the researchers and as we all know these shouldn't be in the bedroom.

Young adolescent boys often sweat heavily at night and that's where our bedding comes into it's own. Pure wool and lightweight allows their body to breathe and let them get a restful nights sleep.
