At night your body enters a long deep sleep which causes your muscles to relax. This can lead to an increased blood flow to your penis, which causes an erection. Believe it or not, this can happen up to 5 times in one night.


Even when you are sleeping your brain still responds to stimulation. If your penis repeatedly rubs up against something the stimulation can cause an erection.


Full bladders may also cause morning wood. Once your bladder fills up, it can stimulate a part of the spinal cord that causes a reflex erection, which helps prevent urination during sleep.
