Research confirms one person is simply a more appealing target. A study with twins highlights how innate body chemistry drives mosquito preference.
The Twin Study
Nineteen fraternal twins and eighteen identical twins took part. Their body odors were wafted through a Y-shaped wind tunnel, then mosquitoes were released.
Clear Preferences Emerge
Identical twins produced even mosquito distribution across both arms, thanks to matching scents. Fraternal twins, sharing fewer genes and distinct odors, saw mosquitoes flock to one side.
Beyond Odor Alone
Body odor clearly matters, but it's not the whole story. Carbon dioxide and other factors also play roles. Ongoing research will pinpoint the mechanisms.
