Only about one in 20 American teenagers get enough sleep and exercise.
That’s from a CDC study published Monday, that looked into the habits of about 60,000 teens.
The conclusion – about 5-percent of them get the recommended amount of sleep and exercise – and don’t spend too much time in front of a screen.
The CDC recommends at least eight hours of sleep per day and an hour of vigorous physical exercise.
One expert says parents need to set an example for their teens that means adults should turn off their electronic devices before bedtime.
They also need to make exercise a family priority and reward teens when they work out more.
