Are allergies making me tired?

Q: When spring comes around, I never know if my lack of energy is a result of allergies or something else. How can you tell the difference?

For the estimated 26% of adults in the United States who deal with seasonal allergies, spring is not just the time to ditch your winter jacket and frolic around outside. It also heralds the beginning of spring allergy season, and the dreaded symptoms that come along with it - runny noses, sneezing, watery eyes - and fatigue, said Dr Jyothi Tirumalasetty, a clinical assistant professor of medicine at Stanford University who specializes in allergy and immunology.

But figuring out if tiredness is a result of allergies or something else - like a cold, Covid-19 or even just the changing of the clocks - can be challenging because many of the signs may be the same. Here are some simple ways to tell them all apart.
