Do Mosquitoes Prefer Type O Blood?

There is generally no scientific evidence to support the claim that mosquitoes prefer to bite people with type O blood. Mosquito bites are typically not directly related to blood type, but mainly depend on the temperature of the body surface and the concentration of carbon dioxide around the body. If the temperature of the body surface is relatively high, or if the concentration of carbon dioxide around the body is relatively high, the sweat secreted at this time may carry a special odor, making it easier to attract mosquitoes. Conversely, if the temperature of the body surface is relatively low and the concentration of carbon dioxide around the body is low, even if a person has type O blood, they are less likely to attract mosquitoes.

If a person is naturally more attractive to mosquitoes, it is important to take relevant protective measures. When going out, spraying floral water, essential oil, or similar products can help repel mosquitoes. Additionally, wearing long-sleeved shirts and pants can help prevent bites. If the skin experiences redness, swelling, itching, or other symptoms that do not resolve spontaneously over a long period of time, it is recommended to consult a doctor for proper treatment. Medications such as Compound Dexamethasone Acetate Cream, Hydrocortisone Butyrate Cream, and Zinc Oxide Ointment can be prescribed by a doctor to provide relief from itching.

It is important to regularly monitor changes in the skin and avoid scratching excessively with hands. If other uncomfortable symptoms arise, it is advisable to seek medical attention promptly for proper management.
