Who is more attracted to mosquitoes?
How to avoid being "targeted" by mosquitoes?
Pay attention to these "mosquito physiques"!
01
People with high concentrations of exhaled carbon dioxide
Some people exhale air with a higher concentration of carbon dioxide, which makes it easier to attract mosquitoes.
02
People with high levels of carbon dioxide in the microflora on the surface of the skin
Some people have ciliates, actinomycetes or staphylococci on the surface of their skin. These bacteria, during their metabolic process, produce carbon dioxide, which attracts mosquitoes.
03
People who like to drink alcohol
After drinking alcohol, the human skin secretes more carbon dioxide, which is also easy to attract mosquitoes.
04
People with a fast metabolism
After exercise, the metabolism accelerates, and the concentration of lactic acid and uric acid in the sweat of the skin increases, and at this time, the concentration of carbon dioxide also increases, which attracts mosquitoes.
In addition, the metabolism of pregnant women is 21% higher than that of normal people, and the body temperature will be 0.5~0.7 °C higher, which is also easy to attract mosquitoes.
05
People who like to wear dark clothes
Like humans, mosquitoes have their own "color preferences". Mosquitoes like dark colors, so when doing outdoor activities in summer, you should try to avoid wearing darker clothes such as red and black to prevent mosquitoes.
Mosquitoes tend to be darker and prefer to move in dark or low-light environments, as such an environment makes mosquitoes feel safer and less easy to detect.
Dark clothes such as black form a dark background that mosquitoes like, and are more "favored" by mosquitoes; Light-colored clothes such as white reflect a stronger light, creating a bright background, which makes mosquitoes feel unsafe and reluctant to approach.
What to do after a mosquito bite?
Don't scratch!
If the subcutaneous tissue and fascia
Necrotizing lesions due to infection
Necrotizing fasciitis may result
Other than that
If one of the following four situations occurs
Prompt medical attention should be met
↓↓↓
● Have a history of mosquito bites, and form large bags with a diameter of more than 1 cm, or appear to be partially packed.
● Within one to two weeks of mosquito bites, there is a persistent high fever.
● After mosquito bites, it is obviously accompanied by joint and muscle soreness.
● The test found that the white blood cells, platelets, and liver function indicators were abnormal.
After being bitten by a mosquito
How to effectively relieve itching?
Experts say
Ordinary people can use cool ointment or toilet water to relieve itching, and if people have severe itching or "big packs", they can apply anti-allergic drugs orally or locally to relieve itching.
However, the method of pinching the word "tic-tac-toe" or "ten" on the mosquito bag to relieve itching is not scientific, this practice replaces the itching with pain, and the bacteria in the nails can also cause infection.
Prevent mosquito bites
These are a few things to do well
01
Take personal protective measures
1. When going to the countryside, parks, streets, and activity venues, try to wear long-sleeved clothes and long pants to reduce bare skin. Or apply insect repellent to bare skin to avoid mosquito bites. If you are taking an infant out, the stroller should be hung with a mosquito net.
2. Use mosquito nets or install window screens when sleeping to ensure that the resting environment is mosquito-free. Hidden places in the office (such as the bottom of the bed, the back of the door, the back of the cabinet) and other places that are not easy to clean can be sprayed with aerosol insecticides to kill adult mosquitoes to ensure that the office environment is free of mosquitoes. At the same time, replace and clean mosquito repellent products in time to maintain their effectiveness.
3. Avoid outdoor activities during times when mosquitoes are active, such as dusk and early morning.
02
Do a good job of environmental sanitation
1. Remove or invert all kinds of idle water containers that can accumulate water outdoors: such as flower pots, cylinders, tires, beverage bottles, etc., which are not used outdoors, on balconies, rooftops, etc.
2. Aquatic plants grown at home (such as Fugui bamboo, evergreen, bergamot, etc.) should be changed every week, and bottles and roots should be washed. During dengue fever epidemics, it is best not to grow aquatic plants, or to use mud and sand instead.
3. Keep the pot tray free of water, and dry it at any time if there is any water.
4. Remove all kinds of useless stagnant water in time: such as ditch wells, rooftops and other ground water, fill bamboo joints and tree holes.
03
Do a good job of self-health monitoring
If you have fever, rash, joint pain and other symptoms, seek medical attention in time, and inform your doctor of your travel history. If you are found to be infected with dengue and other infectious diseases, you should immediately suspend work and go to the hospital for isolation and treatment to avoid infecting others.
