During the day we face a lot of stress, that’s mean we all need sleep. If you fell asleep for one minute 60 separate times, your body wouldn’t gain the same value as if you slept for a straight hour. This happens because there are different physiological responses to the chemicals released by your body and brain when you sleep for a certain amount of time. There are four levels of sleep depending upon the length and quality. Deep sleep, which almost always happens if you sleep for 2+ hours is what enables a full REM cycle, and is healthiest for you with more of ‘long-term benefits’.
The other standard is D2, which can occur as early as 20 minutes. This is why the power nap is effective. While you do not get a full REM cycle, your body and brain feel rejuvenated after D2 sleep. The most effective way to sleep is to maximize REM cycles is when you break your sleep into shorter segments, the chances of completing REM cycles is smaller, but still possible. In this case, power naps can get you through the day, but you may not be as healthy long term as someone consistently getting deep sleep.
In the study that conducted by Najib T. Ayas, MD, which he was testing mechanistic studies and epidemiological studies. Mechanistic studies show that the sleep length results might change the hormonal milieu in the human body. For example, if the person (young male) sleeps up to 4 hours for two nights, the plasma levels of ghrelin hormones were increased and leptin hormones were decreased. Moreover, this experiment shows that the young man experienced significantly increased levels of hunger for various categories of food especially for high carbohydrate foods, also will cause obesity in the future with the young man.
On the other hand, sleeping for 8 hours per night will decreased the level of ghrelin hormones and will increase the level of leptin hormones. In his epidemiological studies shows that many countries have been reported a cross-sectional association between curtailed sleep and obesity. Moreover, the short time of sleep will predict future obesity. Furthermore, the study Patel and colleagues followed 68,183 women for up to 16 years in the Nurses Health Study, and they found out that the women who sleep 6 hours, they gained 0.71 kg more than the women who sleep 7 hours after adjusting for important covariates.
Another Study done by Damien Léger and more researchers about sleeping too much is caused by sicknesses and depression. The long sleepers are facing many problems with sleep disorders, obesity, insomnia, and depression. The researcher had samples on adults students for who sleeps over 10 hours per night. The results show that TST was 7 hours and 13 minutes to be in a normal mood. Sleeping over 10 house will cause you in depression mood that will give a bad day start. The most effective way to sleep is to maximize REM cycles. If you break your sleep into shorter segments, the chances of completing REM cycles is smaller, but still possible.
In this case, power naps can get you through the day, but you may not be as healthy long term as someone consistently getting deep sleep. Many people may be surprised that sleep deprivation has a negative impact on all aspects of life. It affects physical and mental health. In addition, a person becomes more vulnerable to illness and accidents. Although it is not entirely clear what the brain does during sleep, some scientists point out that the brain arranges and stores information, as well as solving problems. It may be noted that the lack of sleep in children may hamper the development of the body and their immune system adequately, according to what researchers see.
Sadness, anxiety and persistent despair are symptoms of sleep sickness and frequent sleep, and there are also other psychological and physical symptoms. Depression is strongly linked to sleep and lethargy. In the psychological factor, it affects a person’s sleep a lot. It may cause depression. It is very common in many countries and appears during the winter and it is known that this type of depression results in the desire to sleep for many hours. All in all, sleeping too much was associated with psychiatric diseases and higher BMI, but not with other chronic medical diseases.
Eventually, The Energy Efficient Responsive Sleeping on Mobile Phones has a new idea for users to be active to read sensor data. Which is makes responsive sleep impractical. They found a new root cause of mobile sensing energy consumption. They have made new mobile phones architecture that uses heterogeneous core-processors to achieve energy efficient responsive sleeping. I believe that the responsive of the sleeping will be also improve the user experience with the phone as if the phone is always on. Also, it has a new prototype called little rock which has benefit for responsive sleep through continuous sensing examples.
