You know about junk food. Now there’s sleep that’s not so good for you: junk sleep. And there’s a good chance that your teenager is getting some. A BBC report says:

Too many teenagers are damaging their health by not getting enough sleep and by falling asleep with electrical gadgets on, researchers say.

A third of 12 to 16-year-olds asked slept for between four to seven hours a night. Experts recommend eight hours.

The Sleep Council, which conducted the poll of 1,000 teenagers, says gadgets in bedrooms such as computers and TVs are fueling poor quality “junk sleep”.

In fact, many experts recommend even more sleep: about 9 and 1/4 hours for a teen. And all seem to agree that removing TVs, computers, phones, and other gadgets is a critical first step.
