On average, how many erections do men experience at night while sleeping for 8 hours?
3-5. In a full night’s sleep, on average, a healthy man has 3-5 erections, each lasting around 30 minutes. Erections often occur while dreaming. Contrarily to popular belief, you do not need to be having an erotic dream to get a nocturnal erection. Erections can occur during any dream. This phenomenon is the reason why men often wake up with a boner, which is commonly referred to as “morning wood.”
