This year's golden autumn October, the cooling comes too fast. For many friends in the region, before they can feel the warm sun in autumn, they have put on down jackets and experience the "cliff-style" cooling of "one night of winter".
The violent temperature fluctuations bring not only somatosensory discomfort, but also many health risks -
"freezing" 7 diseases
The threat of low temperature to the human body is to cause direct disease, and the other is to act on special groups and induce or aggravate the condition.
01Diabetic
Diabetic patients should not be freezed.
1 It is easy to catch a cold due to cold. Long-term or irregular hyperglycemia reduces the phagocytosis of leukocytes , resulting in a decrease in the body's resistance.
The second is to prevent vasospasm. When the blood vessels of the diabetics are suddenly stimulated by cold air, vasospasm will occur, leading to microcirculation disorders, which can easily cause tissue necrosis and diabetes foot .
02 Respiratory Disease
Cold air stimulation will cause airway immunity to decrease and impair function, which will increase airway reactivity, causing symptoms such as cough, chest tightness, and even asthma, dyspnea, etc.
Patients with asthma and chronic bronchitis are prone to recurrence or worsening of the condition.
Everyone has different responses to these stimuli. People with family history and physical sensitivity will be more serious.
03 Gastrointestinal Diseases
When the temperature is low, it is a high incidence of gastrointestinal diseases, because low temperature stimulation will cause capillary contraction, affecting gastric acid secretion and gastric blood circulation, thereby causing acute gastric disease.
, especially for patients with ulcer disease, autonomic neurological disorders may occur, resulting in upper gastrointestinal bleeding in , or perforation.
04Cardous Vascular Disease
Blood vessels may contract due to the stimulation of cold weather, which in turn leads to aggravated heart load and leads to cardiovascular disease attacks.
Therefore, you should be vigilant when the following symptoms occur in the cooling weather:
1. No cause fatigue, chest tightness or sudden angina pectoris occur frequently, worsening the degree, prolonging the time, and the recent arrhythmia , etc.
2. Suddenly palpitations, shortness of breath, unable to lie flat, and constantly burst into foamy and bloody phlegm.
3. Suddenly unconscious and fell to the ground. Dizziness, weakness, slow heartbeat (30 to 40 times per minute), heart rhythm .
4. Primary hypertension patients suddenly drop in blood pressure, are extremely weak, sweating coldly, have pale complexion, and are confused.
If the above symptoms of myocardial infarction occur, you should call "120" to send it to the hospital for emergency treatment.
05 Cerebrovascular Disease
The sudden drop in temperature can easily stimulate the nerves in the body that control blood vessels, causing continuous spasm of small arterioles, causing blood pressure to rise suddenly, and accidents such as stroke also follow one after another.
Therefore, once you find symptoms such as numbness or weakness on one limb, numbness on the face or skewed corners of the mouth, unclear speech, dizziness and vomiting, you must be highly vigilant and go to the hospital for examination and treatment immediately.
06 Prostate Disease
At low temperature, the excitability of sympathetic nerve will be significantly enhanced, causing the prostate gland to contract, causing chronic congestion and increasing pressure in the urethra.
Changes in urethral condition will aggravate the increase of prostate fluid, leading to prostate disease attacks, and symptoms such as frequent urination, urgency, excessive nocturnal urination, pain in perineum and testicles.
It is recommended that patients with prostate hyperplasia should add clothes in time after cooling down, and do not sit on a stone bench when going out.
07 Cold urticaria
Cold is the most common cause of urticaria, and weak people are more likely to be "infected".
The characteristic of cold urticaria is that after being exposed to cold water or other cold substances, itchy edema and wind mass appear in the cold area, which is often found in the exposed area.
For this type of people, it is most important to do a good job of keeping cold and warm. When going out, try to minimize bare skin and keep the skin moist.
The key points to keep warm
01 Hat protects the head
According to research, nearly 20% of the heat in the human body is emitted from the head, so in response to cold weather, in addition to adding clothes, it is important to wear a hat to keep the cold.
02 Wear a mask to protect the lungs
The lungs are an important organ that cannot be isolated from the outside world. When the cold wave comes, the first reaction of most people is breathing discomfort.
In order to reduce the problem of the respiratory system, humidifiers can be used to adjust the humidity in autumn and winter, and windows should be opened to ventilate moderately. People with chronic respiratory diseases should wear masks to reduce and avoid the stimulation of cold air.
03 Wear a scarf to protect the cervical spine
If you suffer from cold for a long time, it will cause cervical spondylosis , shoulder periarthritis , back pain and other diseases.
It is best to wear a scarf or a turtleneck when going out during cold days, especially not to expose the back of the neck.
04 with waist protection and abdomen protection
The navel is different from other parts of the abdomen, there is no muscle or fat tissue under the navel, and the blood vessels are rich.
After catching a cold navel, it is easy to cause gastrointestinal dysfunction in , , and digestive system diseases such as vomiting, abdominal pain, diarrhea, etc.
05 with knee braces and joint protection
There is only one layer of skin wrapped outside the knee joint, without thick fat and muscle protection, and the blood supply is low, so it is very sensitive to temperature and humidity.
The knee joint is prone to degenerative changes due to cold, causing problems such as pain and unfavorable flexion and extension. When the weather is cold, you must wear long-term pants, and if necessary, add warm knee pads.
But don't wear tight shoes, socks, leggings.
06 Choose the right shoe protection foot and ankle
The temperature is low and the blood vessels are contracted, the muscles and ligaments are flexible, and the joint protection strength is weakened. If you are not careful during exercise, you will cause joint damage and fractures.
Wearing the right shoes is also helpful in preventing fractures. Wearing low-heeled shoes and sports shoes can greatly reduce the probability of fractures caused by falling.
