Time For Bed

Sleep – like eating, drinking and breathing – is a basic human need.

Five things you might (or might not) know concerning sleep:

1. every night we experience four or five sleep cycles, which are made up of different stages. Each stage is quite different and is designed to maintain bodily well-being and metal health.
2. when a child or a teenager is in deep sleep, their body produces growth hormones, so maybe there’s some truth in the old saying: ‘early to bed and you’ll grow tall.’ In fact, some newborn babies spend as much as 80% of their time sleep.
3. deep sleep is also the time when the body mends its cells and makes the immune system stronger. If you wake up a lot at night and disturb your sleep cycle, you’ll get ill more easily.
4. if you live average lifetime, you’ll spend about twenty years asleep.
5. a person kept awake for long periods usually dies after about ten days of total sleep deprivation. So, if you didn’t sleep for a few days, you certainly wouldn’t feel good. You’d start seeing things that weren’t there, and you wouldn’t be able to do simple things like counting from 1 to 100.
