why is pollen allergy common in the tropics ?

  • Tree, grass and weed pollen native to tropical climates cause a lot of allergies
  • Pollen from ornamental flowers is carried by insects and is heavy so it does not blow around. As per common belief, roses or other similar flowers do not cause allergies.
  • flowers of grass and weeds are small and their pollen is extremely tiny. This pollen is very light and it gets blown in the wind for hundreds of kilometers
  • Even if you don’t have trees nearby, this pollen gets blown around and mixes with the dust in the house. That is why pollen allergy is common in cities too.
  • Early morning and late evening pollen is more concentrated in the atmosphere. So it is advisable not to go for jogging or walks at that time.
