Power down, sleep well.

If you want to catch up on your ZZZZs, log off your tablet and put away your smart phone. A new study published in the journal Applied Ergonomics suggests that using those devices too close to bedtime can interrupt the release of hormones, like melatonin, that regulate our internal clocks, especially the sleep cycle. Lower levels of melatonin have been linked to obesity, diabetes, and other health problems. Even light leaking from a device can be enough to interrupt the sleep cycle. So turn off the switch and drift away.
