Buds are sprouting, birds are twittering and the convertibles and sunglasses are coming out.

Even though the overnight temperature still drops to near freezing, the flirting season is on. Everyone knows that even the most tender ray of sunshine warms not only the cheeks, but also stirs emotions. Winter coats are aired and scarves loosened as the spirit of spring takes off.

Are all these feelings just a fluke? No, not at all. Although scientists are not in agreement about what causes them, the symptoms are the same: good humour and a tingling in the belly.

"Sunlight and the additional daylight cause an increase in the hormone serotonin and that makes people generally more alert and livelier," said Peter Walschburger, a psychologist at Berlin's Free University. The body also produces less of the sleep hormone melatonin when there is more light. Spirits are lifted and there's an

increase in the desire to flirt and have sex. But that's not all by a long shot.
