Summer, it's mosquito season again. Why do mosquitoes come when the lights are turned off? What attracts mosquitoes is not blood type but sweat? How can we get rid of mosquito harassment? Next, let Xiaobian l answer for you.
Why do mosquitoes come when the lights are off
1. Mosquitoes like the dark
Most species of mosquitoes come out at night to look for food, that is to say, mosquitoes like to eat in the dark environment, so there are many after turning off the light, there are also lights on, but relatively few.
2. Static is easier to attract mosquitoes
Mosquitoes are distinguished according to their heat and taste. You must be still active when you turn off the light. Then your heat and smell transfer is unstable. Once you turn off the light and enter the corresponding stable state, mosquitoes will wait for the opportunity to move.
Can I sleep with the light on to prevent mosquitoes.
Mosquitoes are not able to distinguish objects under visible light, just like human beings. Mosquitoes find prey through infrared and heat perception. However, due to the big difference between the ambient temperature and blood temperature at night, mosquitoes' vision 'is more sensitive at night, and' vision 'is poor during the day, so they are less active in the day and are not easy to see, so they can't prevent mosquitoes when they turn on the light to sleep.
Moreover, turning on the light to sleep will lead to the inhibition of human melatonin secretion, greatly reduce the human immune function, and affect the quality of sleep.
What kind of person is easy to be bitten by mosquitoes
The sweat of human body contains a lot of amino acids, lactic acid and ammonia compounds. Mosquitoes are very sensitive to this. Once they smell these substances, they will have a big appetite.
A man of milk
The baby is easy to be attacked by mosquitoes for two reasons: first, the baby does not have the ability to stand in the way, and mosquitoes are more likely to bite. Second, the baby has a strong and fragrant milk smell, and mosquitoes will bite because of the milk smell.
Wear dark clothes
Mosquitos like to suck blood in low light environment most, because too deep color of clothes has no reflective effect on mosquitos, so they are easy to be bitten by mosquitos, and dark clothes have strong heat absorption ability. Mosquitos also like to bite people with high temperature, which makes people wearing dark clothes more likely to be bitten.
People with high temperature
The mosquito has a heat receptor in its antennae, which is very sensitive to temperature, so that it can lock the 'target' through the antennae 50 meters away. Therefore, people who are big and prone to perspiration are more attractive to mosquitoes. In addition, after exercise, the amount of carbon dioxide exhaled by the human body increases, and the concentration of carbon dioxide in the environment is relatively high. Mosquitoes sensitive to this will smell it.
Pregnant woman
Studies have also shown that pregnant women are twice as likely to be bitten by mosquitoes as other women. This is because the gases exhaled by pregnant women contain a variety of mosquito repellent chemicals, and their abdomen temperature is higher, and the volatile substances on the skin surface are relatively more.
Drinkers
Studies have found that drinking a beer or two outdoors increases the risk of mosquito bites by 15%. According to the analysis of scientists, the changes of body odor and respiration after drinking will make people more likely to attract mosquitoes, and drinking will reduce the body's ability to defend against mosquito bites.
Makeup people
People who make up are more likely to attract mosquitoes than people who don't make up. It is found that many cosmetics, such as hair gel, hand cream and facial cleanser, have strong attraction to mosquitoes because of their special smell.
