Bad morning breath, sweat or sleepy yawns may not be the most suitable aphrodisiacs, but sexologist Glenn Rowan of the Kinsley Center for Sexual Research openly states that the pros far outweigh the cons. From a psychological point of view, waking up with sex brings the couple extremely close. Any person can wake up in a bad mood and in the rush for work or another task, they can be rude to their spouse, just because of the sour mood. Physical contact contributes to an instant and strong emotional rapprochement and a strong psychological connection with the partner, and they, in turn, contribute to good relations throughout the day. From a physiological point of view, morning sex has been proven to increase immunity. The production of immunoglobulin-A (IgA) – antibodies that act against infections in the body – is greatly increased during this morning activity. During sexual intercourse, their production in the mucous membranes of the female genital tract is increased to prevent potential infection with sexually transmitted diseases. After sex, their levels remain significantly higher. A study by Wilkes University in the USA, demonstrated with data: people having sex at least twice a week have over 30% increase in IgA, compared to people who are less sexually active. Sex in the early hours of the day makes for a much more pleasant day, not only because of the intimate and pleasurable contact, but also because serotonin levels in the brain rise during orgasm. The hormone of happiness is available for many hours after intercourse and can even replace the need for coffee.

But the most serious from a health point of view are the advantages it gives to the cardiovascular system. Queens University of Belfast conducted a study of several thousand middle-aged participants over a period of ten years. Scientists from the team found that having sex at least three times a week lowers the risk of a heart attack by about 50%, and here the effect is equally pronounced in men and women who are fans of morning caresses – they guarantee them lower blood pressure, more -great tolerance to stress and a wider smile during the day.
