Frequently asked questions
Is nightfall harmful?
No — nightfall (nocturnal emission) is completely normal and harmless. It does not cause weakness, hair loss, weight loss or infertility.
How can I stop nightfall?
It does not need stopping or treating — it is a normal body process. If it bothers you, be reassured; there is no medical problem to fix.
