Nightfall is commonly also known as wet dreams. The problem of nightfall is very common among men’s in the mid age or adolescent age. The problem of wet dreams is characterized by the unknowingly and involuntarily ejaculation while asleep. It can be seen in both men and women but its more common among male and rare in a female. During the nocturnal emission, the men may wake up and again go back to sleep.A nightfall or nocturnal emission is considered
to be a problem only if it is very frequent or if it is persistent even when the male has crossed adolescent age. In either of these case, it is essential to seek a doctor’s advice.
Frequent masturbation, watching pornography or such pictures, discussing sex or adult talks makes a person victim of the nightfall. Also, certain medicines or drugs such as sedatives, tranquilizers,
and high BP medicines can lead to nocturnal emission. Apart from this the mental state of mind (Stress, depression, anxiety etc.) and also no or less physical activity (Obesity, long sitting hours, inactivity) of a person accounts for wet dreams.
