A chiropractor taught you to choose a mattress. The harder the mattress, the better?
There are many reasons that affect the quality of sleep, both physically and psychologically. However, unsuitable mattresses can also cause people to "sleep without sleep". According to a "Sleep Quality Opinion Survey of Hong Kong People", 566 Hong Kong residents over the age of 18 were interviewed by random telephone last month, and it was found that 83% of the respondents had experienced different sleep problems in the past 3 months, among which the most The five most common problems are: feeling tired after waking up (58%), waking up earlier than scheduled (49%), waking up in the middle of the night (42%), difficulty falling asleep (38%) and having nightmares (25%) ).
The firmer the mattress the better?
Is it normal for Hong Kong people to "sleep well"? Dr. Wang Junhua, a chiropractor, said: Even in our clinic, many patients suffer from poor sleep quality, but they do not face it. Based on the above-mentioned survey figures, we can see why I have not slept well for more than 3 nights a week. When it comes to choosing a mattress, many people think that the harder the better, and even think that people in the past slept on the ground, what does the hardness of the mattress have to do with it? Wang Junhua said that people's lives and work patterns are very different in the past and present. We are now working in the office for a long time, facing the computer for more than ten hours, and our muscles will be strained, so we need adequate rest. He said that when lying down on the mattress, supporting the physiological curvature from the side, the cervical, thoracic and lumbar vertebrae should be S-shaped. Muscles are fully rested. If it is not supported, the muscles will not be able to rest for a long time, resulting in imbalance, resulting in joint dislocation and compression, and pain will follow. Therefore, the mattress should be moderately firm and soft, which varies from person to person, depending on the body weight and body curvature, and the required support force of the mattress varies.
BMI data to help choose
One of the simple guidelines is to choose mattresses according to people's BMI. Wang Junhua explained that adults with a standard BMI of 18.5 to 23 can choose a medium-firm mattress, while those below 18.5 can choose a softer mattress, and vice versa. Choose a firm mattress. If a lighter person sleeps on a hard mattress, there will be a gap between the back and the back due to insufficient pressure, resulting in a lack of muscle support; while a heavier person sleeping on a softer mattress will The waist is formed into a C-shape and sinks downwards, causing the lumbar muscles to be stretched and compressed, resulting in back pain and affecting sleep. The calculation method of BMI is: BMI = weight (kg) / height (m2), Wang Junhua pointed out that this method is not very accurate, but it can be used as a reference for choosing a mattress.
1 minute mattress support test
Since the bearing capacity of the mattress is very important, Wang Junhua pointed out that if you feel muscle discomfort or fatigue after waking up for 3 or more days a week, you might as well perform a "1-minute quick test". The method is: Lie flat on the mattress and ask someone to help you place one palm around the waist. If only fingers can be placed between the lumbar spine and the mattress, it means that the current mattress support is still sufficient. As for those who are accustomed to sleeping on the side, the bridge of the nose and the spine should be in a straight line when lying down, and whether the spine and the feet are parallel, otherwise the supporting force of the mattress may have been damaged. There are many people who wake up with backache and back pain. How to distinguish whether it is their own problem or a mattress accident? Wang Junhua pointed out that the existing pain symptoms may not appear when you wake up. If the joints are dislocated, they will appear all day long, especially when sitting patiently and after work, the pain and paralysis will be more serious. If it is related to the mattress or bedding, people are usually most tired after a day's work. The moment before going to bed, after a night's sleep, the pressure on the spine, muscles and intervertebral discs will be relieved, and it should be the most comfortable time to wake up. If there is pain for more than half of the week after waking up, it may be related to the mattress or bedding.
