In fact, it’s not enough to just wash the pillowcase. Due to long-term use, the oil secreted by the human body’s epidermis, exhaled air, shed hair, dander and other substances will enter the pillow; moreover, the pillow will also Deformation occurs due to long-term use. Therefore, it is necessary to change pillows regularly. If you do not change pillows for a long time, what harm will it bring to your health?

For latex pillows, replace every 3 to 4 years; for down pillows, it is appropriate to replace every 2 to 3 years; pillows such as tea and buckwheat need to be replaced once a year. ; Chemical fiber pillows need to be replaced every 3 months.

In addition to timely replacement, what are the precautions when using pillows?

1. The height of the pillow

A pillow that is too high can easily damage the cervical spine and induce snoring; while a pillow that is too low can cause cerebral vascular congestion, increased blood pressure, and feel dizzy after waking up. A reasonable pillow height should be behind the pillow, and the torso and head are parallel when lying on the back; Therefore, the most suitable height of the pillow should be 10-15 cm. Many people only put their head on the pillow while sleeping, and the neck stays in the air for a long time, or the neck muscles are stretched or contracted for a long time because of the improper height of the pillow, and they cannot fully relax and wake up. The back of the neck will have a sore sensation, and in the long run, it will develop intractable neck and shoulder pain, even dizziness, and headache. ​From the perspective of human biomechanics, concave (dumbbell-shaped) pillows are most suitable. Elderly people can put their head in the depression of the pillow, and put the neck on a higher place, so that the neck can get enough support and the neck and shoulder muscles can be relaxed. Regarding the height of the pillow, it is advisable that the head does not fall back or bend excessively when lying on the back, and the head does not curve sideways when lying on the side. To ensure the above two points, the ligaments and joints of the neck can be in a relaxed state, so as to achieve a better rest effect.

2. The hardness of the pillow

If the pillow is too hard, it will cause discomfort due to the less contact area of ​​the head with it; if it is too soft, it will easily cause neck fatigue; therefore, the hardness of the pillow must be moderate. A very hard pillow has a small contact area with the head, increased pressure, and uncomfortable scalp. On the contrary, the pillow is too soft to maintain a certain height, the neck muscles are prone to fatigue, and it is not conducive to sleep, and the head sinks during it, which affects blood circulation. Therefore, the pillow should be of moderate hardness.

Pillows should also have a certain degree of elasticity. If the pillows are too elastic, the head will continue to be subjected to additional elasticity, causing muscle fatigue and injury. Such as "spring pillow", "air pillow", etc., can not be regarded as a pillow that is conducive to health.

Pillows, this seemingly ordinary daily necessities, can't imagine that there is so much attention to its use. For the sake of health, we should not neglect the issue of pillows.

Correct use of pillows

1. When lying on your back (sleeping on your back), first use a pillow to cushion the entire head to the neck, not to the shoulders, otherwise the cervical spine is likely to be compressed, and it is not possible to sleep on the pillow with only half of the back of the brain, which will cause the cervical spine to hang in the air; Another small pillow is cushioned under the knees, so that the knee joints can be in a state of mild flexion and relaxation. The doctor said that the wrong position of the pad may cause soreness and discomfort in the short term, but it will cause greater health problems in the long term.

2. When sleeping on the side, the width of the shoulders will cause the head and neck to hang in the air. The height of the pillows should be doubled. You can use 2 pillows stacked together.
