Sleep 8 hours a day will make you die faster?
head frequently during the day, Monday morning is always very difficult to get out of bed again? If so, you will conclude:
harm caused by lack of sleep, I believe we are all familiar: the low energy, slow, memory loss, reduced immunity, and even premature aging of the body?? The most common argument is that an adult should be have sleep time is 7-8 hours, but an experiment in the University of California has obtained a sensational conclusion:
the experiment up to six years, from the College of Pharmacy and the University of California, San Diego, conducted jointly by the American Cancer Society. They are a million between the ages of 30 and 102-year-old object was observed. In this experiment, the age, medical history, health and so on have been taken into account, they are with their physical condition with a similar object for comparison.
study found that sleep is only 6,7 hours a day person, than those who slept more than 8 hours, or less than 4 hours a much lower mortality rate. Among them, those who slept 7 hours a day lowest death rates, and even those who slept 5 hours, this factor should also lower than people who sleep 8 hours enough.
Although research indicated that mortality and sleep time for correspondence between cause and effect, at present more evidence needed to prove, but it certainly gives us a new reminder: we need to sleep much in the end?
In fact, sleep is not down in the pillow, quilt cover sleepless night, and then opened his eyes and wake up so simple, it is a complex gradual process. Why do we sometimes wake up, the body will magically restore power, and sometimes still feel tired than before going to sleep it? This is the depth and the state of sleep caused by the difference.
University of Chicago researchers, in the thousands of volunteers have recorded brain waves during sleep, the body's sleep cycle revealed: during sleep, the body first into the slow-wave sleep, rapid eye movement after a sleep, repeat after beginning the night about 4 to 6 sleep cycles.
often wake up that night, or not get enough rest before waking up, and they sleep rhythm is very confusing, EEG have shown in various stages of rapid, sharp movements, and the wave is suppressed type, which is in the normal sleep invisible.
Therefore, only full for a good 4 - 5, the depth of sleep, the body's physiological function can be fully repaired, the immune system can be strengthened, and the energy can be fully complementary. Extend the sleep time does not necessarily make up for their lack of sleep, on the contrary, if blindly in bed, but did not get quality sleep. This is not good for the body but it may even shorten your life.
researchers explained that when your body is still waking up in bed, you reduce the exposure to the sunlight, because the body temperature will be inactive long become too low, which secrete large melatonin - a hormone the body can contribute to sleep - so you will feel the next day, more tired and sleepy. And this will prevent you sleepy at night into the deep sleep.
cycle of this vicious cycle continues, the result is that your sleep system is weakened. Physiological rest period is disrupted, the body can not get enough energy, perhaps lower your immune system.
In fact, those who sleep more people, not because they need a long sleep, but because they did not properly take care of your sleep system, causing the system is weakened and can not work efficiently. They feel a lack of energy during the day, they tend to think: / p>
In fact, those who slept 6,7 hours for people to wake up naturally, woke up lying you do not hard enough for 8 hours, as long as you feel clear-headed, feel good to get up activities safely it. Think long-term lack of sleep, how sleep is also not enough, perhaps you should own a little strict, adjusting the alarm, the sleep time and have a regular cycle control more. Sleep too much and overeating is a reason, and to eat eight full, and perhaps is the most healthy. Therefore, even if still feel sleepy after the point, you should convince yourself Do not rely on the bed. In addition to a regular sleep and avoid caffeine and alcohol, regular exercise and other daily commonplace advice, in order to improve sleep, we can also learn about the National Sleep Association tips:
follow the sun with the ups and downs: as much as possible to get up at sunrise, or get a very bright point of light. Bright light will make the human body clock to adjust to the best condition. Every day in the sun in the morning for an hour, you will feel as lively as ever, and easier to fall asleep at night.
Do not lie in bed staring at him : If you really can not sleep lying down, then, do not boil dry on the bed. Up somewhere else doing something to relax, take a look at books, newspapers, listening to music or watch television until you feel tired so far, just to avoid their too excited. Dry sense of anxiety in bed, often makes you more difficult to sleep.
adjust room temperature: the temperature adjusted to a comfortable state of the room too hot or too cold will make your body tense, and thus more difficult to fall asleep.
