Just five bad nights of sleep can put your body in a pre-diabetic state, and if you are a man it can lead to a dramatic reduction in testosterone, according to a recent report commissioned by the Federal Government.
Structurally, the torso and pelvis are generally similar in size, so the key is aligning and squaring the head and lower extremity. A good pillow should align your head with your upper body if you’re a side or back sleeper.
We should spend nearly 1/3 of our life in bed. Sleeping really well is especially important if you’re spending less time than that. Improving our sleeping position and environment can help posture pains, as well as giving us a better nights sleep.
Everyone knows sleep is important, but until recently no one knew exactly why.
Now research shows that waste products from the brain’s metabolism accumulates in the fluid surrounding nerves during the day, and then gets flushed out and eliminated when you sleep. The fluid is called cerebro-spina fluid (CSF), and the study found poor sleep was associated with a buildup of a substance (b-amyloid) in CSF associated with Alzheimers.
Many of us don’t get enough sleep and even fewer do enough exercise. So, do we hit the snooze button to get an extra hour of sleep or drag our sorry selves out of bed to squeeze in a workout before work?
