Nightfall, often referred to as a nocturnal emission, is a common occurrence for teenage boys, especially during the times of puberty. It’s essentially an involuntary ejaculation that happens during sleep. This natural process can be attributed to hormonal changes as the body transitions through puberty. At 15, your son is within the age range where such phenomenon are expected, and they usually become less frequent as hormonal balance stabilizes.
Nightfall itself is not something to be worried about medically. It’s typically a sign that the reproductive system is becoming fully functional. However, embarrassment or confusion about these changes is also quite common. Your support can be crucial in helping him understand that what he’s experiencing is entirely normal. Education on the subject can also reassure him that this doesn’t reflect anything abnormal about his health.
From a Siddha-Ayurvedic perspective, nightfall might sometimes be attributed to imbalances in the doshas, particularly pitta, which can be increased by certain lifestyle and dietary factors. It might help to look at his diet - excessive spicy, oily, or heavy foods, especially during evening, may cause disturbances. Encourage a balanced diet, rich in fresh vegetables, whole grains, and plenty of water – these can help maintain equilibrium in his system. Ensure he has a regular sleep routine, and try limiting stimulating activities an hour before bed, like intense video games or screen time.
For practical advice, talking to him openly yet gently about these changes can be beneficial. Explain in straightforward terms that he is going through a natural stage of growth. Encourage questions from his side and try to answer them honestly without too much technical jargon, maintain a calm demeanor to diffuse any awkwardness. By understanding that his body is reacting normally under the circumstances, he might find comfort.
Should you observe any drastic changes in behavior, mood, or prolonged distress surrounding these events, it might be worth consulting a healthcare professional to rule out any mental discomfort it may be causing him. Remember, communication and understanding form the key pillars here.
