Looking Forward to Fighting Spring Fever

Feb. 11, 2007
Dear Mayo Clinic:
Every year when the weather changes from cool to warm, I am exhausted until my body adjusts. My father calls it "spring fever." What causes this, and what can I do so that I'm not so tired? -- Port Jefferson, N.Y.

Answer:
While spring fever isn't a medical condition -- there are spring- related factors that could contribute to your seasonal fatigue. Possibilities include:

Being out of shape: Many northerners get more sedentary over the winter. When it's cold, snowy and icy, and there are fewer daylight hours, it's common to get less exercise and maybe put on a few extra pounds. On those first warm days, when you wash windows, do yard work or take a long walk, your body may feel the effects of a long winter. Activities that you easily tolerate in the fall might tire you in the spring.

Allergies: Another reason for spring fatigue is seasonal allergies. Allergies or allergy medications can contribute to fatigue. If you take allergy medications, talk with your doctor or pharmacist about medication options to minimize fatigue as a side effect.

Even if you've never been diagnosed with seasonal allergies, check with your doctor to see if your fatigue could be related to allergies. Sometimes, allergy symptoms are subtle. A specific spring pollen could be what makes you tired. When you start regaining your energy, it could be that the pollen count is down. You can develop seasonal allergies anytime in your life.

Changes in sleep patterns: It seems basic, but are you getting less sleep in the spring? When daylight lasts longer, it could be that you are staying up later and that's contributing to your fatigue.

This winter, work to stay physically active. When spring rolls around, go slow with new activities. If fatigue shows up again, consider asking your doctor about seasonal allergies.
