Poor sleep patterns associated with poor health as well. Chronic sleep deprivation leads to several health difficulties like high blood pressure, obesity, depression, irregular hormone production, immune system weakness, memory loss, irritability and decreased concentration.
Here are a couple of things going on human organs during sleep as reported by Dailymail , on Wednesday (12/29/2010):
1. Brain
Despite seemed passive, not active and brain activity decreased about 40 percent, but the brain remains extremely active as long as you sleep.
typical night’s sleep consists of five diverse sleep cycle , each lasting about 90 minutes. Four of the very first phase of each cycle is considered as quiet sleep or non-rapid eye move-ment (NREM). The last stage referred to as rapid eye movement or rapid eye movement (REM).
During the initial stage of sleep is the brain waves of small undulations. During the second stage, these waves are interspersed with electrical signals, known as sleep spindles , which is tiny bursts of activity lasting a few seconds and make the scenario calm.
The third stage occurs a significant slow waves , the bigger and slower brain waves eat sleep will deepen. At stage four, 50 percent of brain wave slowing. At this point, 40 percent of normal blood flow in the brain was transferred to the muscle to restore energy.
REM sleep is the highest level of brain activity. This phase is generally associated with dreams, triggered by the pons, which is component of the brainstem that send nerve impulses between the spinal cord and brain.
2. Eye
Although closed, the eye throughout sleep can keep moving. Eye movements showed a distinction in the stages of sleep, the most rapid movement occurs throughout REM sleep (rapid eye movement).
3. Hormone
Throughout waking, the body burns oxygen and food to present energy. This condition is known as catabolic rate is dominated by stimulation of adrenal hormones and kortisteroid.
But during sleep, the hormone system will switch on anabolic phase, ie the conversion of energy to the improvement and growth. At this stage the level of the hormone adrenaline and corticosteroids down and the body begins producing growth hormone (human growth hormone or HGH), melatonin, as well as sex hormone testosterone, fertility hormones, FSH (follicle-stimulating hormone and the hormone LH (luteinizing hormone).
Fri HGH boost growth, maintenance and repair muscles and bones by facilitating the use of amino acids. Although melatonin is a hormone produced to assist individuals to sleep. This hormone is secreted by the pineal gland deep within the brain, it helps control body rhythms and cycles sleep-wake.
4. Immune System
An increasing production of immune system and particular proteins during sleep, as a specific agent who fight the illness . Killer cancer known as TNF (tumor necrosis factor) is also pumped by means of the blood vessels during sleep. This is why adequate sleep can help fight infection.
5. The temperature of the body
At night, the body temperature along with the adrenaline started to fall. Sweating may possibly happen in an effort to try to combat the loss of body heat.
6. Skin
Over deep sleep, accelerated rates of skin metabolism and many body cells show increased production and reduced damage to proteins. This is what causes a good night’s sleep can beautify the skin.
7. Respiration
When asleep, the throat muscles will relax so that the narrow throat every single time you breathe in air. Snoring occurs when the throat narrows and part of the airway to vibrate.
8. Mouth
Saliva is required to lubricate the mouth and to eat. But during sleep, reduced salivary flow, causing dry mouth in the morning. Even so, the mouth can be extremely active throughout sleep, that causes people unconsciously gritting teeth during sleep.
9. Muscle
Although men and women can change position to sleep about 35 times a night, the muscles remain relaxed body . This offers an opportunity for networks to be repaired and restored.
10. Blood
The heart rate decreased between 10 and 30 beats per minute during sleep. This would result in a decrease blood pressure, which occurs in deep sleep. During the break, the blood flow from the brain, relaxes the arteries and makes the limbs bigger. The cells and tissues that break down to produce toxic waste also turn into less active during sleep. This offers an opportunity for damaged tissue to be rebuilt.
11. Digestive System
Throughout sleep, the speed will slow down the digestive system. For this reason, eating late at night is not recommended simply because the enzyme and gastric acid which is utilized to convert food into energy is not running, so it can accumulate in the body of calories.
