Recent researches and practices show that the new corona variants are more likely to spread through the air in a closed environment, with the air conditioner on. Within 36 hours after exposure to the pathogen, one person has been tested positive and in some cases, one passed it onto others 2 days after exposure.
Up to now, implementing the 5N (5 Nos) rule and vaccination against COVID is still the optimal strategy recommended by many countries. This message has reached people in the communities of many countries to help prevent the COVID epidemic effectively. But since the discovery of new variants of the SARS-CoV-2 virus, many supportive solutions are recommended to increase the effectiveness of epidemic prevention and control, of which the concern is to increase the ventilation in the residence of each individual and groups of family.
Many studies have concluded that a well-ventilated and hot environment from sunlight will drastically reduce the activeness of the new corona variant as well as the risk of spreading infection of most respiratory viruses. It could be said that “to open the door for ventilation and sunlight is one of the best remedies for respiratory viruses. So what should we do now to limit the environment we live in and reduce the density of viruses in the air, in order to avoid the infection of the new virus variant?
Ways to prevent yourself from the new corona variant:
-
Keep everything organized, tidy and clean the house daily
For items inside your home or private room, you must arrange them neatly and scientifically. Vacuum, clean the surface of the house, furniture, handles, handrails…, especially the nooks and crannies and under the cabinets and beds that are easy to miss. Remove dirt and unused furniture for easy daily cleaning and sanitizing. The better you do this, the more you eliminate the virus’ hiding places.
-
Ventilate the house, receive sunlight
Opening the door helps to ventilate the house, creating continuous convection air currents, thereby rapidly reducing the virus density in the air, especially when there are people in your home who are suffering from respiratory viral infections such as colds, flu…. The virus is easily spread in the air when coughing and sneezing. When sunlight enters your home, the air will naturally warm up, creating a high-temperature environment that is not suitable for the growth of respiratory viruses.
Common characteristics for respiratory viruses like to live in places with low temperature and humidity, the most suitable is below 25 degrees Celsius such as an environment with an operating air conditioner. In an environment that is both sunny and at a high temperature of 30 degrees Celsius or higher, the respiratory virus can only exist for a short time and will be destroyed, helping to reduce its ability to spread and reduce infection. many times.
In addition, the sun also brings you many unexpected valuable benefits:
– Helps you to live longer:
A study of 30,000 Swedish women, followed for more than 20 years, found that those with less sunlight exposure lived 2.1 years shorter than those who did not. spend a lot of time outdoors. However, be careful because too much sun exposure can increase the risk of skin cancer. Measures should be taken to protect the skin such as wearing protective clothing, sunglasses and applying sunscreen.
– Make you happier:
Sunlight has the ability to help the body release beta-endorphin, which improves mood and makes you feel happier. Sunlight boosts levels of serotonin, the body’s natural happy hormone. Indeed, we tend to feel happier and more energetic when the sun is shining. In addition, exposure and exercise in sunlight can help prevent depression.
– Help you sleep better:
A study by the University of Colorado-Boulder, USA, found that natural light from the sun can help regulate circadian rhythms and regulate the body’s sleep-wake cycle. When the body is regularly exposed to sunlight, the sleep cycle will be more tightly regulated and sleep better.
– Helps the body produce adequate vitamin D:
Vitamin D deficiency is associated with many health problems such as high blood pressure, diabetes, cancer, aging, and an overall risk of death. Sunlight is still the richest natural source of vitamin D. Having two hands and your face exposed to the sun for about 15 minutes a day can provide you with 3,000 to 5,000 IU of vitamin D.
