Surprise! more original bed die faster

We really need to sleep?

The day often head "venting" or drowsy? Monday morning always difficult out of bed? if so, you will conclude that: "I sleep!"

Lack of sleep the hazards posed by, I believe we are familiar with: energy powers, unresponsive, memory loss, reduced immunity, and even premature aging of the body??

The most common argument is that an adult should have sleep time is 7 to 8 hours, but an experiment of the University of California, has come to a startling conclusion: "sleep eight hours a day will make you die faster. ”

The experiment lasted for six years, from the University of California at San Diego School of medicine, and the United States to join forces with the cancer society.

They have a million age is between 30-year-old and 102-year-old observation of objects. In this experiment, the subject of age, medical history, health, etc. have been taken into consideration, they are told and their physical condition similar object for comparison.

The study found that daily only sleep 6, 7 hours of sleep over more than 8 hours per day, or less than 4 hours of human mortality.

Of these, 7 hours of sleep per day were the lowest rates, and even sleep 5 hours, this coefficient is less than 8 hours of sleep.

Although research indicates that, with regard to mortality and sleep time of causal relationship, you also need more evidence to prove, but it certainly gives us a new reminder: we really need to sleep?

Sleep is a systems engineering

In fact, sleeping and not down on the pillow, cover a hostel on the quilt sleep a wink, and then open your eyes to wake up so simple, it is a complex gradient.

Why do we sometimes wake up, your body is magic recovery of strength, but sometimes feel tired than before going to bed? this is what is sleep depth and status are different.

Researchers at the University of Chicago, thousands of volunteers had a sleep time of EEG recording, reveals the human sleep cycle: in sleep, the body begins to enter the slow wave sleep stage, after a period of rapid eye movement sleep, then repeat, one night about 4 ~ 6 sleep cycle.

Those who often wake up at night, or have not rested before people wake up, they sleep rhythm is very confusing, EEG figure in the stage show that fast, rapid movements and inhibited the wave type, which in normal human sleep is not seen.

Therefore, only be good 4 fully-5 period of deep sleep, the body's physiological functions can be fully repaired, the immune system can be strengthened, but the energy can be fully complementary.

Extension of the sleep time and may not be able to compensate for their lack of sleep, on the contrary, if you simply rely on the bed, but did not receive high-quality sleep. This is rather unhelpful, it even will shorten your life.

The researchers explained that when your body to wake up but also rely on the bed, you shorten the time in contact with sunlight, temperature can also be because your body long inactive and becomes too low, thus producing a lot of melatonin, a sleep can promote human hormone — so that you the next day will feel more tired and drowsy.

This will prevent you to sleep at night into a deep sleep.

This vicious cycle, the result is your sleep system is weakened.

Biological rest period is interrupted, your body can't get enough energy, and reduces your immunity.

Sleeping too much and satiety is a reasonable

In fact, those who slept more people, not because they need long time to sleep, but because they did not take care of your own sleep system, causing the system to be weakened, will not be able to work efficiently.

They felt the lack of dynamism in the daytime, tend to think: "I slept too little will to sleep. "Instead of asking yourself:" I sleep quality is not good enough? how can we improve? "

In fact, for those who have only slept for 6, 7 hour natural wake up, wake up, don't hard lie enough for 8 hours, as long as you think of your mind and feel good, it is safe to get active.

Long-term think how lack of sleep, sleep not enough people, maybe you should own strict, fine alarm clock, sleep time and cycle control with some regularity. Sleeping too much and satiety is a reason, eat eight minutes to eat, perhaps is the most healthy. Therefore, even to the point you feel trapped, you also should convince myself don't rely on the bed. In addition to the regular sleep time, avoid caffeine and alcohol, daily exercise and so cliché advice, in order to improve sleep quality, we can draw on a United States national sleep Association tips:

Don't stay in bed look on in despair: If you lay really sleep, don't do go on on the bed.

Up to other places do relax, take a look at the newspapers, listening to music or watch TV until you feel tired, just to keep myself too excited. Stem lying in bed feeling of anxiety, tends to make you even more difficult to sleep well.

Adjust the room temperature: room temperature adjusted to comfortable, too hot or too cold in the room, will let your body tension and thus more difficult to sleep.

Follow the Sun and the ups and downs: as much as possible in the sun rises up, or get up point a very bright light.

Bright light will let the human biological clock adjusts to the best State. Every day in the morning sun on one hour, you'll feel energetic and at night to sleep more easily.
