Thickened down jackets, scarves, gloves, hats, non-slip shoes...Here's what I need for today! Full of temperature, full of security! Be healthy and healthy.
It's so cold today! The sharp cooling in a short period of time makes me shiver, I should Xi learn from you, wear more, strengthen personal health protection, and travel healthily.
Healthy travel is also an important embodiment of practicing a healthy lifestyle!
HealthyMaster the guidelines for health protection and travel healthilyIn order to guide the public to respond to the cold wave scientifically, improve their awareness of self-protection, and reduce the health damage that may be caused by the cold wave, the National Bureau of Disease Control and Prevention issued the "Guidelines for Public Health Protection of the Cold Wave", putting forward protection suggestions for different key groups to protect public health to the greatest extent.
In the face of cold wave weather, there are three main categories of key protection groups recommended in the Guidelines:The first category is sensitive groupsSuch as infants, children, pregnant women, the elderly, etc.; 
The second group is people with chronic underlying medical conditionsIf you have cardiovascular and cerebrovascular diseases,
people with respiratory diseases, etc.;
The third category is outdoor workersSuch as traffic police, sanitation workers, construction workers,
Couriers, delivery people, etc.
Guidelines for Public Health Protection during Cold Waves1. The basic concept of cold waves
A cold wave is a weather event in which cold air from high latitudes invades the middle and low latitudes on a large scale and causes severe cooling (according to the standard of GB T 20484-2017, a cold wave refers to a daily minimum temperature with a cooling range greater than or equal to 8 within 24 hours, or a cooling range greater than or equal to 10 within 48 hours, or a cooling range greater than or equal to 12 within 72 hours, and the daily minimum temperature in the place drops to 4 or below, and the daily minimum temperature decreases continuously within 48 hours and 72 hours).
2. Health risks of cold waves
A drop in temperature can cause the body's blood vessels to constrict and increase the respiratory rate. During the cold wave, cold weather is easy to cause superficial damage and form chilblains, aggravating the pain of patients with arthritis and rheumatoid arthritis. It is easy to induce airway spasm and abnormal immune function of the respiratory system, causing acute exacerbation of chronic obstructive pulmonary disease, acute attack of bronchial asthma, acute respiratory infection and other respiratory diseases. It is easy to cause cardiovascular and cerebrovascular diseases, such as angina, myocardial infarction, arrhythmia, acute heart failure, transient cerebral insufficiency, stroke, etc. At the same time, it may also aggravate urological and endocrine diseases, such as chronic kidney disease, diabetes, etc.
3. Key protection groups
There are three main categories of people: the first group is sensitive groups, such as infants, children, pregnant women, the elderly, etc.; The second category is people with chronic underlying diseases, such as cardiovascular and cerebrovascular diseases, respiratory diseases, etc.; The third category is outdoor workers, such as traffic police, sanitation workers, construction workers, couriers, food delivery workers, etc.
Fourth, cold wave meteorological warning information
According to the "Cold Wave Warning Signal and Defense Guide", there are four levels of cold wave warning signals.
5. Guidelines for graded protective measures
In view of the level of cold wave warning signals, we put forward suggestions for graded population protection measures.
