No. In fact hayfever isn’t a fever at all, and isn’t necessarily caused by hay. The condition was named by a British doctor back in 1882 when he noticed that his symptoms worsened during the hay harvesting season.
But nowadays, the term is widely used to describe the blocked or runny noses, sneezing and irritable eyes associated with plants that pollinate or moulds that produce spores, usually in the late spring, summer or autumn. It is also the name given to allergies caused by indoors substances like dust mites and pet dander (loose skin flakes).
Not exactly. We love our dogs and cats but it’s true, they can cause allergies, though hair isn’t the main reason.
It’s the protein secreted in their skin and saliva that creates the problem. That’s why cats are thought to cause more allergies than dogs, because they spread the proteins to their coats through grooming.
