Research results on sleep habits and a new hypothesis about pillows and beds for good sleep

1. Research results on sleep habits

According to foreign sources such as CNN, the US Harvard Medical School and Israeli Deaconses Medical Center co -research team recently studied the effects of sleep habits on their lifespan.

First of all, the team sleeps for 7 to 8 hours a day with good sleep habits. There were five things, including words.

CNN added that it would be helpful to follow the method of sleep hygiene to sleep well. This includes ▲ falling asleep and waking up at the same time on weekends and holidays ▲ making a cool and dark optimal environment ▲ avoiding drinking before going to sleep ▲ Prohibition of using blue light an hour before sleeping.

2. A new hypothesis about pillows and beds for good sleep/Eam Taekyoung

Introducing my personal research results in relation to sleep. According to my study, there are two important things that people don't know about sleep. The shape of the pillow and the slope of the bed. These are things that affect the posture of the body of sleep.

Sleeping with a typical pillow can reduce the function of the respiratory and cardiovascular function by shrinking the chest in the long run. In the back of the skull, there are two relatively flat places on the left and right, which is an evolutionary product to keep a person stable when a person lies. These places help not to tilt too much from the left and right when they sleep, and to change their posture intermittently.

Considering the shape of this skull, the pillow looks good to have a structure as shown below. When you lie down right away, the pillow height is low, but it can prevent it from being tilted from side to side. When you lie down to the side, you can put it on the high area of the pillow so that the cervical spine can be horizontal.

However, when you lie down right away, the downward tilt is formed from the stomach to the esophagus (see Figure 3). Therefore, it is easy to cause gastroesophageal reflux disease in a relatively short period of time. I actually experienced. Therefore, if you need to choose either, it is a good choice to prevent problems that can occur in the short term by not using too low pillows.

But why don't you use a slope bed (see Figure 4) and a low pillow (see Figure 2) at the same time? This will theoretically solve both problems. According to the article from Medical News Today, a sloped bed seems to have been proved to have a positive contribution to snoring, sleep apnea and blood circulation.

I did not actually use the slope bed in Figure 4 and the pillows of Figure 2. It is just the theoretical hypothesis.
