Why winter is cold and flu season – what can you do
A cold doesn’t make you cold, but it doesn’t help.
Being cold doesn’t literally make you cold, as long as your wet hair leaves home, no matter what your parents say. But it seems that the coldest season is the cold season.
Not all types of diseases are actually more common, but when the weather gets cold, we do see a slight similarity between the cold and the flu that we like and the diseases of the respiratory system. That’s why – what you can do.
The flu really thrives in winter
There is no doubt that the flu virus has thrived in the cold in some way. In the United States, autumn and winter flu activity peaks. And in the southern hemisphere, the virus hit our hardest hit in the summer – the coldest time in the world.
It turns out that the basic design of the virus is to jump between people when the air is cold and dry. Studies have shown that when temperature and humidity are low, transmission rates are highest. Because cold air naturally has less water, low humidity is packaged with winter. Even when we warm the air to make our home comfortable, it stays dry unless we use a humidifier.
There may be some factors at play: cold air may help flu viruses survive outside the human host for longer, making it easier to cry after coughing or sneezing. The study also showed that the virus did better in a low-humidity environment. Infected individuals exhaled viruses wrapped in tiny drops of water. If the air is dry and desperately filters out water from any source, the droplets will evaporate more quickly. If the flu droplet contracts fast enough, it can become so light that it circulates in the air instead of falling to the ground.
You spend more time indoors
Speaking of rough dry heat, you’re more likely to get sick simply because you spend more time inside. This means that you are more often close to other people, breathing the same circulating air. Offices and schools are particularly dangerous. In 2014, the study found that a single doorknob pathogen could infiltrate the entire building in a matter of hours. The surface of the lounge is particularly vulnerable to the spread of the virus.
In this case, the only offense is a good defense. Try to pay attention to what you are in contact with and who else may come into contact with it, and in the contact surface of potentially harmful bacteria and touch your face or food between practice good to wash their hands (or use hand sanitizer).
Solution: try to work from home when you’re sick. Use hand sanitizer after contact with a Shared surface (especially in a working kitchen and bathroom) and remind your child to let his or her hands (and boogers)
A cold won’t make you sick, but it does make you more likely to get sick
In addition to making the flu virus easier to circulate, the cold, dry air also makes your mucous membranes rough. This is why the respiratory system disease, the cause of the general increase in winter, in order to protect the respiratory system from pathogens, mucus should besmear is on the respiratory system, cold air will make beneficial snot out.
Seasonal changes can also cause allergic reactions when we are exposed to different types of pollen and dandruff. When your nose is running and your throat is itchy, your mucus membranes are stimulated and vulnerable – making it easier for opportunistic viruses to replicate at home. Persistent allergies can also lead to secondary bacterial infections in your throat or sinuses.
There is also some evidence that our immune system may be hit in the winter, whether due to the cold itself or lack of sunlight.
If you’re sick, I’m sorry. This is our guidance, the real work of cold medicine.
