However, each person's physiological and genetic differences will have different attraction to mosquitoes. Some people may be more attracted to mosquitoes, while others are relatively less bitten by mosquitoes. This difference may be influenced by many factors, including heredity, immune system and chemical composition in blood.
As for why it used to be easy to be bitten by mosquitoes, it seems that mosquitoes are not recruited now, which may be related to the following factors:
1. Physiological changes: With the changes of age, health status and hormone level, the chemical composition of human body may change. These changes may affect the mosquito's reaction to human body.
2. Differences in immune system: Differences in immune system will also affect the frequency of mosquito bites. The immune system's response to mosquito bites may change over time, or some components of the immune system may inhibit mosquito bites.
3. Environmental factors: Environmental factors may also affect the frequency of mosquito bites. For example, the current living and working environment may be different from that of childhood, and these changes may affect the distribution and number of mosquitoes.
In short, the frequency of mosquito bites varies from person to person and may be affected by many factors. Everyone's situation is unique. If you find that you are no longer bitten by mosquitoes, you can observe whether the surrounding environment and personal living habits have changed, or consult a doctor for more information.
