Because you have too little time for sleep

As you struggle to make time for your life outside of your long hours at work, something has to give.

Sometimes you get a full night’s sleep, sometimes you don’t.

You think you’re stronger than most, you think you’re sturdier than most, you think you can get away with less sleep than most, at least on occasion.

You can’t.

Get less than seven or eight hours sleep tonight, and you’re significantly impairing your concentration, memory and learning tomorrow.

Get less than seven or eight hours sleep night after night, and you’re significantly increasing your risk of cancer, strokes, heart attacks, obesity, diabetes and dementia.

By spending less time sleeping so that you can spend more time working, you’re significantly shortening your life.
