Asthma is more common among women than men, which might be related to a correlation between asthma and the hormones estrogen and progesterone, says Payal Patel, MD, a member of the American Academy of Allergy Asthma & Immunology. Asthma may get worse before and during your period or improve during pregnancy, Dr. Patel says. “This goes along with the theory that oral contraceptives can improve lung function due to reduced fluctuations in hormone levels,” she says. These are other unusual menstrual cycle symptoms to watch for.
Just because a cat or dog doesn’t shed doesn’t mean you’re safe from their irritants. Allergens can be found in urine and saliva, in addition to dander, Dr. Patel says. “Even pets labeled ‘hypoallergenic or nonshedding’ can trigger asthma,” she says. Stop falling for these common myths about allergies.
