How to disinfect if someone has a cold at home

If there is a cold patient at home, you can pour white vinegar or rice vinegar into a pot and boil it, then put the boiled vinegar in a container in the room to evaporate. You can also spray a certain proportion of 84 disinfectant, alcohol or other disinfectants at various locations in the home, or open doors and windows frequently for ventilation, which can also play a role in disinfection.

If there is a cold at home, you can use vinegar to disinfect. The specific operation method is to pour white vinegar or rice vinegar into a pot and boil it. Then put the boiled vinegar in a container in the room. When the smell of rice vinegar fills the room, it can play a role in disinfection and sterilization.

Disinfection with disinfectant is a common disinfection method, and the more common disinfectants are 84 disinfectant and alcohol. When using disinfectant to disinfect your home, you need to dilute the disinfectant according to a certain proportion, and then pour the disinfectant into a spray bottle and spray it at various locations in the home.

When there is a patient with a cold at home, you can also open the doors and windows of the house frequently for disinfection. When the indoor air flows to the outside, the virus in the indoor air will also flow to the outside. And opening the doors and windows can replace the indoor and outdoor air, and the indoor air can always be kept fresh.

Can masks protect against cold viruses?

Masks can protect against viruses, but the filtration rate will vary depending on the mask specifications and the size of the virus particles. Viruses are mainly nanoparticles that start to spread after combining with water and dust in the air. The filtration rate of ordinary masks is 80%, which can reduce the degree of droplet transmission to a certain extent. Professional masks are still mainly N95.

Masks can protect against cold viruses, but this is determined by the specifications of the mask and the size of the virus. Generally, the diameter of most viruses is between 10 and 300 nanometers. After merging with moisture and dust in the air, they form larger particles that can be filtered by the many layers of filter fibers in the mask.

Another function of the mask is to prevent the spread of droplets. Cold viruses are often transmitted through sneezing and talking, so wearing a mask can block some droplets, so that droplets carrying cold viruses cannot directly infect the human mouth and nose, thus reducing the chance of infection. However, the filtration rate of ordinary masks is only 80%.

The use of N95 masks can block most cold viruses and is a more suitable mask specification. However, N95 is a medical protective mask with a service life of only 6 to 8 days. If you do not pay attention to maintenance during use, the service life will be reduced. When using N95 masks, remember to store them in a ventilated and dry place.

How long does cold medicine stay in the body?

Generally, cold medicines can be eliminated from the body within 48-72 hours, but viraviril will affect the mitosis of tissue cells. After the medicine is eliminated, it will still have an impact on the body. It is recommended to drink more water and eat more fresh fruits and vegetables to speed up the excretion of the medicine.
