What are the common causes of colds? Who is more likely to catch a cold?

People often think that contact with many people will make it easier to get infected. Therefore, it is easy to catch a cold. In fact, the immune system can "remember" all kinds of germs it has come into contact with. So what are the common causes of colds? What kind of people are prone to catching a cold? Let's see what the Encyclopedia Knowledge Network says!

What usually causes a cold?

1. Environments where people gather

The gas exhaled by people contains various kinds of bacteria. At this time, in places where people gather, such as shopping malls, cinemas, amusement parks, subway stations and other public places, the density of bacteria in the air will increase, and the types of bacteria will also be richer. Staying in such an environment for a long time will make you extremely susceptible to infection by pathogens and cause viral colds.

2. Mood swings

There are two aspects of mood swings: impatience and depression. When people are impatient, their bodies generate internal heat. If they are slightly exposed to the cold, it will be like using too much air conditioning, causing a cold. When people are depressed, they don't eat or drink well, and their body's resistance decreases, which can cause a viral cold.

3. Sitting for a long time

People who often sit indoors for long periods of time, lack sunlight, have poor indoor air circulation, and have poor blood circulation. Their ability to cope with indoor and outdoor environments decreases, and their immunity decreases, making them more susceptible to colds. Therefore, it is necessary to exercise frequently when you have nothing to do.

4. Overwork

Working overtime frequently can also easily cause a cold. This is because when people sleep, they produce immune molecules. If you often work overtime, which leads to lack of sleep, the immune molecules decrease, and the immunity decreases, people are more likely to be infected by bacteria and viruses, causing colds.

What kind of people are prone to catching colds?

1. People with few friends

People often think that being in contact with many people makes it easier to get infected. In fact, the immune system can "remember" the various germs it has come into contact with, so being with family and friends often enhances people's ability to defend against diseases and relieves mental stress.

2. People who diet excessively

Fat can inhibit the function of immune cells, so women in particular should pay special attention to their weight. But don't diet too much to lose weight, otherwise it will cause steroid secretion disorders and reduce immunity.

3. People who suffer from chronic constipation

Frequent constipation will not allow the intestines to have "free time" to fight against germs. Danish research shows that supplementing the diet with probiotics can shorten the duration of colds by 48%. Recent studies in Thailand have also shown that probiotics can resist colds. Therefore, during the flu season, you can eat some foods containing probiotics, such as yogurt.

4. People who love to stay in bed

Lack of sleep will reduce immunity, and you should ensure 8 hours of sleep every day. Professor Ronald Eccles, director of the Common Cold Research Center at Cardiff University in the UK, reminds us that too much sleep will slow down blood circulation and cause the immune system to not function effectively.

What causes cold and diarrhea?

1. This situation is quite common. Generally, antibiotics or antiviral drugs are used after catching a cold. While treating the cold, it will affect the balance of the normal intestinal flora, resulting in diarrhea.

2. It should be the gastrointestinal dysfunction caused by the cold. First of all, it is best to take intravenous treatment, oral multi-enzyme tablets to help digestion, and oral Huoxiang granules to relieve vomiting. Do not eat indigestible, greasy or cold food. Eat porridge.

3. According to the situation described, it is a gastrointestinal cold, which is caused by a virus. Gastrointestinal cold is a type of cold, which manifests as gastrointestinal discomfort, such as nausea, vomiting, abdominal pain and diarrhea.

If the gastrointestinal effect is ideal, ciprofloxacin and lijunza can be used. If there is a concurrent viral infection, ribavirin and morphine hydrochloride can be used. Paracetamol (acetaminophen) can be used to reduce fever. If the condition is serious and causes stomach cramps, dexamethasone can be used for emergency treatment. The treatment of gastrointestinal colds mainly focuses on rest. On the one hand, patients should rest more to reduce physical exertion and enhance the body's strength to fight the disease.

Prevention is the key, including strengthening exercise, improving physical fitness, living a regular diet, and improving nutrition. Avoiding colds and overwork can help reduce susceptibility and is the best way to prevent colds.
