How to prevent cold and heat in summer?

Cause: Most colds in summer are caused by catching cold, and most colds in winter are caused by infection.

Generally speaking, the occurrence of a cold is due to a series of cold symptoms such as nasal congestion, runny nose, headache and general pain caused by viruses or bacteria. Summer colds are rarely spread in public places by cold patients like winter colds. Summer colds are mostly caused by the sudden cold of the body, which cools the blood, reflexively causes temporary ischemia of the nose and throat, weakens the resistance, and makes the cold virus take advantage of it. Experts specifically analyze the causes of hot colds as follows:

First, due to the hot summer climate, the human body sweats more, and sweat gland secretion consumes a lot of energy. Second, the days are long and the nights are short in summer. The sultry weather often affects people's normal sleep and rest, resulting in insufficient sleep. Third, in summer, many people have poor appetite, mainly light food, which affects protein's intake. Because of the hot weather, some people don't want to exercise, which reduces the exercise time. These factors will reduce the body's resistance and increase the chance of getting infected with the virus, thus causing a cold.

In addition to the above objective reasons, people's own ignorance of hot colds is also the reason for the aggravation of the disease. Many people are too eager to be cool, like to take a bath with cold water, wash their hair and sleep under the air outlet of the air conditioner ... these greedy behaviors are easy to catch a cold.

Symptoms: A cold in summer can easily induce other diseases.

Summer is hot and humid. There are two kinds of common colds. The first is wet and cold in summer. Fever, a small amount of sweating, but often sweating but at a loss, heavy head drowsiness, dry mouth, loss of appetite. Second, the common cold caused by summer heat, mostly manifested as dizziness or headache, sore throat, fever, sweating, but sweating, joint pain, thirst, fatigue, upset.

In addition to the common cold symptoms, summer colds also have internal heat phenomena such as thirst and upset. In early summer, patients with cold will have a runny nose, dizziness, fear of cold, sweating a lot, upset and thirsty, and weakness of limbs. The whole process is more serious than the symptoms of common cold. This will pose a threat to young children, the elderly and the infirm. Children with colds and fever are prone to convulsions and coma in summer; Old people often catch a cold complicated with pneumonia in summer, which is easy to induce stroke, myocardial infarction and other critical diseases. However, if the sickly people catch a cold all summer, it is easy to make the old disease relapse and aggravate the condition.

Sometimes a cold in summer can lead to nephritis. There is a certain incubation period after upper respiratory tract infection or skin purulent infection in summer, which is generally 1 ~ 2 weeks. Some patients will have symptoms of nephritis after the symptoms of acute infection are relieved or subsided. The main manifestations are hematuria, edema, elevated blood pressure, headache, nausea, loss of appetite and other systemic symptoms. Acute nephritis is mostly related to hemolytic streptococcus infection, and it is easy to be complicated with acute nephritis nephrotic syndrome, acute congestive heart failure, hypertension and so on. If you have symptoms such as hematuria after a cold, you should go to a regular hospital in time. Otherwise, if acute glomerulonephritis is not completely controlled and clinical symptoms and urinary protein persist, it will evolve into chronic nephritis. Therefore, avoiding or reducing upper respiratory tract and skin infections is the key to prevent nephritis.

Chinese medicine believes that Yinqiao Jiedu Pill can be used for patients with mild symptoms of hot cold. If the symptoms are severe and accompanied by sore throat, you should choose Lingqiao Jiedu Pill. In addition, 30 grams of fresh reed rhizome and 0/5 grams of fresh mint/kloc-can be used instead of tea to treat mild colds. Patients with high fever can decoct Folium Clausenae 65438 05g, Bidens bipinnata 65438 05g and Commelina communis 30g with water.

Treating a cold requires the right medicine, but in the process of daily self-treatment, the abuse of cold medicine often occurs. Some people think that people who are exposed to colds should take cold medicine to avoid being infected. The western medicine for treating colds is mainly antipyretic and analgesic drugs, which can only alleviate some symptoms of colds and have no effect of enhancing resistance, antibacterial or antiviral. On the contrary, long-term use of antipyretic and analgesic drugs may lead to leukopenia, which will reduce the body's resistance and make it more susceptible to infection.

Other patients take several cold medicines at a time because their cold symptoms are serious or they have not improved after taking one medicine. Cold medicine contains the same or similar ingredients, so it is easy to overdose when taken together, and the side effects of the medicine will also accumulate. The toxic and side effects of cold medicine will not only reduce white blood cells, but also cause gastrointestinal reactions, and even cause ulcer perforation, bleeding and liver and kidney damage.

Some patients have symptoms such as runny nose, sore throat, fever and general malaise, thinking that they have caught a cold. After taking the medicine, they will sweat and their body temperature will drop, but after a few hours, their body temperature will rise again, and so on for several days. Some people don't have a fever, but symptoms such as cough, headache, joint pain and vomiting don't get better or even get worse. It's dangerous for them to take cold medicine instead of seeing a doctor. Because this may not be a simple cold or not at all, taking medicine according to a cold may delay the illness. Many diseases also have symptoms such as fever and headache, so it is necessary to find a doctor for diagnosis and symptomatic treatment.

Prevention: Daily habits are the key.

1. Reduce the time for "incubating" air conditioners.

In summer, due to the large temperature difference between indoor and outdoor and poor indoor ventilation, it is easy to cause colds and fever. Experts advise not to neglect your health for the sake of temporary comfort. The hotter the weather, the more you should strengthen heat-resistant exercise and reduce the time in air-conditioned rooms. White-collar workers working in an air-conditioned environment, it is best to use air conditioning as little as possible when they get home, especially not to rush into an air-conditioned room as soon as they enter the room. In addition, household air conditioners should be cleaned regularly, because dust mites in dust are the most important allergens.

2. Give priority to light food

Summer diet should be light, avoid greasy, spicy and cold food. Mung bean porridge, lotus porridge, lotus leaf porridge and jujube porridge are all family meals suitable for summer, which have the function of heatstroke prevention and cooling. In addition, it is also important to drink more water. Especially after eating a lot of high-salt and high-sugar foods, water can help restore water and vitamins in the body and avoid thirst and low immune function.

As a food to prevent colds, animal liver should be the first choice. Because the liver contains a variety of vitamins, especially a lot of vitamin A and more vitamin B 12, these vitamins can enhance the body's resistance and effectively prevent colds.

3. Get enough sleep and combine work and rest

Chinese medicine believes that staying up late is easy to hurt people, so we should ensure adequate sleep in summer nights. Of course, after a proper rest, we should also cooperate with proper exercise. If you stay at home or work all day and hold the computer, it is easy to reduce your immune function and lead to a cold.

Step 4 keep a good mood

The heat is unbearable, and many people are prone to depression and even lose their temper in summer. We should know that people who are often worried are prone to decline in immune function, and the body's ability to kill and devour pathogenic microorganisms is weakened, giving the pervasive respiratory virus an opportunity. Therefore, keeping a good mood and an open mind can also play a role in preventing colds to a certain extent.
