11種「蚊選之人」:多汗、O型血的人較容易被蚊咬?

2023/07/10

夏天常常被蚊咬十分困擾?被蚊咬的後果可大可小,輕則紅腫、痕癢,重則可感染登革熱、日本腦炎等疾病。1 研究顯示,大約有20%的人比其他人更常被蚊子叮咬。2 究竟是什麼原因導致這些人較為「惹蚊」?又有什麼有效的防蚊大法?以下就為你一一講解,讓你於夏日遠離蚊咬。 

蚊子「最愛」的11種人: 

  1. O型、AB型血: 這兩種血型較吸引蚊子,而蚊子可從人體皮膚發現訊號,從而分辨其血型3-5 
  2. 呼吸頻密:蚊子能探測二氧化碳,越頻密地呼吸會排出越多的二氧化碳,從而吸引蚊子
  3. 體溫高:蚊子受熱力吸引,因此天氣炎熱或運動時更容易被蚊子叮咬
  4. 多汗:汗水含有的酸性物質入乳酸(Lactic acid)會吸引蚊子8
  5. 皮膚上較多細菌:皮膚上的細菌會轉化成氣味,皮膚問題如濕疹,亦會增加被蚊子叮咬的機會
  6. 孕婦:孕婦比其他人呼吸較頻密,而且體溫較高 10 
  7. 小朋友:小朋友的體溫較成人高 7,11 
  8. 喝酒:喝酒導致口腔的氣味及體味改變,而蚊子更受這種氣味吸引12 
  9. 重口味飲食:常吃甜、辣、鹹味及含豐富鉀質的食物13 
  10. 深色衣物:蚊子喜歡降落在綠色、黑色的地方14 
  11. 噴香水:香水的氣味容易吸引蚊子,特別是花香調的氣味15 

預防蚊叮貼士

  • 穿著寬鬆、淺色的長袖上衣及長褲
  • 遵照產品標籤上的說明,於外露的皮膚及衣服上塗上含避蚊胺(DEET)成分的昆蟲驅避劑
  • 如房間沒有空調設備,應裝置蚊帳或防蚊網
  • 在門窗等入口處放置驅蚊器
  • 避免使用有香味的化妝品或護膚品
  • 保持環境清潔
  • 防止積水,以避免蚊子滋生
