Frozen shoulder, or periarthritis of the shoulder joint, is a chronic disease that occurs around the age of 50, hence the name "fifty shoulders.".
Frozen shoulder can cause functional impairment of the shoulder joint, mainly manifested as shoulder pain, limited mobility, etc., and in severe cases, even simple actions such as combing hair and washing face are difficult to complete.
In order to avoid the quality of life affected, everyone should pay attention to the prevention of frozen shoulder in life, especially those at high risk of frozen shoulder, and should do a good job in prevention. So, who are at high risk for frozen shoulder?

1. Women aged 45 to 55
Most women will enter menopause at the age of 45 to 55, during which the estrogen secreted by women in the body is greatly reduced, resulting in a decline in high-density lipoprotein levels, and the body cannot metabolize excess lipids.
These lipids are deposited in the blood vessels, which will block the blood vessels, affect the flow of blood, make the joint tissue lack blood supply, and eventually produce an inflammatory response, causing pain, including the shoulder joint.
2. Teachers
Some people in special occupations are also prone to frozen shoulder due to long-term chronic damage to the shoulder joint.
For example, teachers need to often write lesson plans or write on the blackboard, although it does not require a lot of effort, but the shoulder muscles need to be involved for a long time, over time, the shoulder muscles, muscle keys and other soft tissues can occur chronic damage, inducing frozen shoulder.
3. People who have been suffering from cold for a long time
Cold in the shoulder is also one of the important factors that induce frozen shoulder. The shoulders are invaded by cold moisture, which can lead to muscle spasms, nerve edema, and over time, the shoulders can be sore and limited movement.
Therefore, whether it is young or old, they should do a good job in life, especially young people, and cannot ignore warmth for the sake of image.
4. People with trauma to the upper limbs
Some people due to upper limb trauma, the need for upper limb fixation during recovery, such as shoulder fixation for too long, may lead to per shoulder tissue atrophy, adhesion, these pathological changes can lead to shoulder joint dysfunction, resulting in pain, limited function problems.
5. People over 50 years old
Frozen shoulder is high around the age of 50. This is because with the increase of age, the body's organs, tissue function degradation, if there is soft tissue damage, metabolic disorders at this time, it is difficult to repair, resulting in the body's muscles, tissues atrophy phenomenon, which naturally includes the shoulders.
6. People who have maintained the same posture for a long time
Maintaining the same position for a long time will also increase the risk of frozen shoulder, such as some people play mahjong for a long time, and the shoulder length is in the same position, which can lead to excessive tension in the muscles of the neck and shoulder area, and over time, it will induce frozen shoulder.
In addition, if the pillow is too high when sleeping, the normal physiological curvature of the cervical spine will change, resulting in damage to muscles and ligaments, an inflammatory response, and an increased risk of frozen shoulder.
Frozen shoulder, although not life-threatening, seriously affects the quality of life of patients. Therefore, the above high-risk groups must pay attention to the prevention of frozen shoulder, usually avoid maintaining the same position for a long time, avoid pillows too high when sleeping, do a good job of cold protection and warmth, usually can move more neck and shoulder areas, promote local blood circulation, and also help prevent the occurrence of frozen shoulder.
