According to research data, people who have sex as soon as they wake up are significantly more optimistic for the rest of the day. They also have a stronger immune system, compared to those who use this time in the morning to have toast with a cup of tea or coffee for example. It is also indicated that those who have sex in the morning have a lower risk of catching a cold or flu. The strengthened immune system is due to an increase in the levels of IgA – antibodies that protect against infections. The appearance and health of the hair, skin, and nails also improve. During intercourse, the hormone oxytocin, also known as the “love hormone”, is released. Compounds that increase estrogen levels are also released, which improves skin and hair tone and texture.

Mornings are the perfect time for short intimate caresses, as everyone is most likely in a rush then, and the increased adrenaline heightens the sensation of the whole experience. A 2009 study found that daily sex improves sperm quality and can increase the chances of getting pregnant.
