Spring Fever?

Do you suffer from "Spring Fever?"
Symptoms include a flushed face, increased heart rate, appetite loss, restlessness and daydreaming. 

"Spring fever is not a definitive diagnostic category," says Michael Terman, of Columbia University Medical Center. "But I would say it begins as a rapid and yet unpredictable fluctuating mood and energy state that contrasts with the relative low [of the] winter months that precede it."

In winter, the body secretes high levels of melatonin, a hormone that governs sleep-wake cycles. Come spring, the increasing amount of daylight is registered by light-sensitive tissue in the eye, which signals the brain to stop secreting so much melatonin. As the hormone's levels drop off, greater wakefulness results. On the other hand, levels of another chemical, serotonin, rise in spring. This mood-elevating neurotransmitter may be at the root of the giddiness, energy boost and enthusiasm that characterize "spring fever."


 Take advantage of your newfound energy! 
Get outside and take in that vitamin D (but not without your sunscreen!)
