Help me doctor .. tell me any natural or ayurvedic medicine ... my age just 18 years old :( [/INST] Greetings. Inability to control emotions allow a male to get too excited during sleep which causes nightfall & making the organ small which is a normal phenomenon until & otherwise its within the normal physiological limit of an individual. Most of the people have many wrong ideas about nightfall - that it causes ill effects on health like nervous weakness, reduced energy, etc. or sexual problems like impotence in the future all of which is NOT true and these are just myths and misconceptions provided they are within certain limit. For too much stress, i advice you to do activities(Play outdoor games you like / Read books/ get along with friends / meet your relatives/ etc., ) that relaxes mind keeping you fresh. </s>
