During sleep, people recover from the physical and emotional stresses and injuries. They also dream. The book, Making Life Choices written by Debruyn, MS in Nutrition, a Ph.D in Biology from the Washington University and working as a contributor in The Worldwatch Institute says, people who had regular, adequate sleep were physically younger for their years than people who did not. This Straight Talk explores the importance of sleep and dreams and tells what is known about their effects on health.
I’ve always wondered what goes on during sleep. What exactly does sleep do for me? This question is difficult to answer. Even though people spend a third of their lives sleeping, no one seems to know for sure what goes on during all that time. However, we know some of the things that happen physically: the blood pressure falls, breathing and heartbeat slowdown, the muscles relax, and the body temperature falls. Perhaps most important, growth hormone is released at almost no time other than during sleep. Growth hormone provides growth and renewal of body cells. It is probably growth hormone that brings about the physical recovery that sleep brings.
If a person doesn’t get enough sleep, all the body systems work less and less well. People become irritable, can’t concentrate, think slowly, and lose coordination. If deprived of sleep long enough, people may start feeling confused, begin seeing imaginary things, or even feel that they are going insane. Irregular sleep or chronic lack of sleep over years can shorten life. Other problems with too little sleep include fatigue, reduced ability to work, and increased risk of heart disease and digestive disorders. A few reports suggest that going without sleep for many months may even prove fatal, although such reports are extremely rare. However, people who do not sleep enough at night tend to nod off during the day. This can be dangerous if they are driving. Drivers who fall asleep at the wheel cause 6,000 auto-related deaths a year.
People’s sleep needs vary. About 2% of adults habitually sleep ten hours a night, and some even more. Children need more than eight hours of sleep a night. Babies sleep 16 hours or even more; most adults, about six to seven hours. These differences seem to reflect the rate of cell growth, which is fastest in the young and which slows throughout life. Amazingly, though, by the age of 60, you will have slept for about 20 years of your life.
I’ve heard that an hour of sleep before midnight is worth two afterward. There’s nothing special about the hour of midnight. It is true, however, that early hours of sleep are deeper than others and therefore, more restful. You go through several stages during sleep. First, after you start to sleep. your body temperature falls, and your brain slows its activity. At this point, you may suddenly jerk half awake- the sign of a sudden burst of brain activity hat signals that start of the first stage of sleep. During the first stage of sleep, your muscles relax, and your heartbeat slows down.
Minute’s late, you enter the second stage of sleep. The brain activity slows still more. Your eyes roll from side to side, but if they were to open, they would not see. This last for about half an hour; the third and fourth stages of sleep bring very slow brain activity, relaxed muscles and even breathing. This is the deepest sleep of all. It occurs mostly in the early hours of a night’s sleep.
It is during the deepest stage that REM sleep occurs. (REM stands for rapid eye movements). The rapid eye movement seems to reflect dreaming, as if the person’s eyes were following the actions of the dreams. You cycle several times a night through REM, into other stages of sleep, and back into REM.
That’s amazing when you had no idea what’s going on while we are asleep. What do you suppose it’s all for? We don’t know. But we do know that REM sleep seems to be essential to a person’s well-being.
People deprived of REM sleep become hostile, irritable and anxious. When sound sleep is again possible, people who have been deprived of REM sleep will experience longer periods of REM to make up for what they’ve missed. This is one reason why sleeping pills may actually harm people. Many of them interfere with this important phases of sleep.
People who drink alcohol, consume caffeine or consume cigarettes may also be interrupting their normal sleep patterns without knowing it. Even a single alcoholic drink before bed time has caused abnormal stoppage of breathing in sleep experiments. Caffeine and nicotine, the drug of tobacco, are both stimulants and can change the brain’s activity to prevent normal sleep.
Images in dreams may be symbols of real-life events. The following dream symbols can be interpreted in many ways, and most experts rely on the dreamer’s interpretation.
Accident: something that has shocked or hurt the dreamer.
Actor: a desire for public attention.
Alien: Some aspect of the dreamer’s personality that seems out of character and foreign.
Alligator: being gripped by fears’ ideas or urges that arise from inside.
Baby: The dreamer as an infant, who needs café from others in order to survive.
Basement: Unknown feelings, hidden motives, memories of the past.
Beach: The line between the conscious and unconscious mind, and deep ideas and feelings.
Blindness: a refusal to admit or understand something.
Bomb: explosive emotions of the dreamer that may harm others.
Burial: Fear of death, or fear of disturbing memories.
Butterfly: a change, emotional or physical from something undesirable to something desirable.
Cat: Understanding and knowledge.
Chicken: Fear of abuse by others.
Clothes: The dreamer’s body image or a preferred image shown down to others.
Fish: The inner, unconscious self.
Flying: mastery of a new skill.
Frog: Unconciuos knowledge, and the power to change.
Ghost: An old lingering fear.
Legs: Support systems, such as parents, friends and religion.
Lightning: release of tension or revenge.
Mermaid: Love of which the dreamer is not aware.
Olive: Peace, love and kindness.
Rainbow: Harmony.
Sand: Passing of time.
Shampoo: Trying to forget or come to terms with something negative.
Test: Fear of failure.
