NEW YORK (Reuters Health) - Immunosuppressants and enzymes that the body poses for sexual intercourse work to fight colds and their unpleasant symptoms, a new study suggests.

Colds are common this time of year, with the weather getting colder and the sky heavily cloudy. Every people on earth has their own cures for colds, which in fact only reduce their disturbing effects and symptoms. But most of these treatments agree on one thing: comfort and drinking herbal teas of all kinds.

Neurologist Manfred Scheidlowski, however, offers another type of treatment. Neuroscience is a field of medical science that combines the study of the nervous system and the immune system.

"Having sex is a miracle cure for a runny nose and a lot of fun," explains the Swiss specialist.

Shidlovsky discovered that the number of natural killer cells in the blood increases by 150% after reaching orgasm. Killer cells are a pillar of the human immune system that recognizes and kills the body's cells infected with bacteria or viruses.

"Sex makes you healthy," says German immunologist Peter Schleicher in Munich. A study by the two scientists found that the human body increases the production of antibodies "immunoglobulin" in those who have sex twice a week. This substance directly helps in the common cold and increases the body's general defenses.

A third benefit for the treatment of colds is sex.
