3. TV

It seems that almost every day new research emerges on the effects of TV and sleep. Of biggest concern, is bedtime viewing. Not only does the light from television throw off our natural circadian rhythms, which are normally controlled by daylight, but the sights and sounds of television act as a brain stimulant, further preventing sleep.

The scariest part of TV’s effect on sleep is that nearly everyone is doing it. A very recent, large-scale survey found that television viewing accounted for nearly 50% of pre-bedtime use!

Do yourself a favour and unplug.
