What are air conditioning legs? The so-called air conditioning leg means that after the air conditioner is turned on indoors, the cold air will sink, so the temperature near the ground will be relatively low. Especially some office workers are used to putting a small electric fan under their desks. If they wear miniskirts or shorts to work every day like Amy OL mentioned above, their bare knees will easily catch cold, their legs will ache and even their joints will ache.
Clinical experiments show that 80% of air-conditioned legs are caused by working, studying or living in low-key air-conditioned rooms for a long time, 60% of patients are middle-aged and elderly people over 45 years old, and 30% are young people aged 65,438+08-30 years old, most of whom are female patients.
Why are there air-conditioned legs? What are the symptoms? When people are in a low temperature environment, the blood vessels on the body surface will contract, which will slow down the blood flow and slow down the supply of various nutrients and oxygen needed by the human body. The knee joint supports the human body, with few peripheral blood vessels and poor blood flow velocity. If you wear shorts and short skirts, your knee will be exposed to low temperature, and your knee will suffer from cold for a long time, and your blood circulation will be slow, which will easily lead to edema and inflammation, which will easily lead to joint diseases such as bursitis and synovitis.
Usually because of air conditioning legs, it will cause knee pain, resulting in inflexible or difficult movements. Sitting for a long time will make your knee joint stiff or sore. It's hard to go up and down stairs, and it's even harder to squat down.
To avoid cold legs, please do three things. Therefore, office workers who look forward to staying in the office for a long time and like to show off their knees must beware of this potentially healthy "cold leg" and do the following three things.
1. Don't adjust the temperature of the indoor air conditioner too low: generally, it is best to control it between 25 and 27 degrees Celsius. Don't let your body, especially your knees, blow directly at the air conditioner or electric fan, so as not to hurt your knees directly at low temperature.
Second, try not to wait in the air-conditioned room for a long time: limit the time to blow the air conditioner every day, and don't stay all day. If you work or live in an air-conditioned room, it is recommended to leave the air-conditioned room during lunch break to give your body a chance to adapt to the normal outdoor temperature.
Third, keep your knees warm: if you have to stay in a low-temperature air-conditioned room for a long time, female friends had better wear trousers and * * * to protect them; Or cover your knees with a towel to protect them. Men suggest getting up regularly to exercise your knees, speed up blood circulation, or wear pants to avoid getting cold on your knees.
