There’s no cure for spring fever, but there appears to be an explanation for it.

This is one fever you don’t mind having. Symptoms often include the urge to stay outdoors, go for a walk or take off your shoes and daydream under the rays of the sun.

Seriously, spring fever may be a real phenomenon, according to psychologists at University of North Carolina School of Medicine.

The excitement of spring’s warm weather may trigger the brain to secrete endorphins, pain-relieving chemicals that fill you with feelings of well-being.

Sunlight is linked to the body’s production of melatonin, a neurotransmitter that regulates sleep and your overall body clock.

Sunlight also boosts production of Vitamin D, which is important for calcium absorption for strong, healthy bones.

What about spring fever and love? In a sort of snowball effect, if spring weather entices you to become more active, the activity then helps to improve your mood.

When you’re in a good mood you tend to smile and feel good about yourself, and this is attractive to the opposite sex.

It is nature’s way to remind us that humans may be affected by an instinctive mating season when they give in to the lure of spring fever.
