How important is sleep?
Sleep is food for the brain. People aren't usually aware of it, but it is necessary for a healthy life. New research is constantly being done to help scientists understand the different ways that sleep affects our body and mind. About one third of your life is spent asleep, which means that in your lifetime you will sleep for about twenty-five years.
How much sleep should we get?
It depends, but most people don't get enough. You should get used to sleeping the same amount every night. Avoid sleeping less during the week and trying to caatch up at the weekend. This will make you feel more tired. Eight hours a night is probably the best for most peope. However, according to recent studies? teenagers need at least 9.5 hours to sleep. In fact, some schools are considering starting lessons later to help with this.
What happens if we don't get enough sleep?
Lack of sleep is unhealthy, even dangerous. It leads to low levels of concentration and harms your memory. And remember, a brain hungry for sleep won't stay awake forever. It will fall asleep even when you don't expect it, perhaps when you are behind the wheel.
Does everybody dream?
All human beings spend about 2,100 days dreaming in their lifetime.Some dreams are scary and some don't make any sense. Until the age of three, babies only dream about other people, and from that age they have lots more nightmares than adults, until they are seven or eight years old. Even blind people dream. People who are born blind don't see images but they dream with the senses of sound, smell and touch as well as with emotions.
What is the most common nightmare?
Research shows that most people have dreamt that they were being chased by someone. Dreams about drowning or being trapped are also high on the list. We dream about lots of horrible things, but luckily within five minutes of waking up, half of the dream is forgotten and within ten minutes, 90% is gone.
