Dropping off to sleep straight after sex is a sign that you and your partner have a strong and meaningful relationship, according to evolutionary psychologists.
The team from the University of Michigan and Albright College in Pennsylvania claim nodding off after sex is associated with a greater desire for bonding and affection.
'The more one's partner was likely to fall asleep after sex, the stronger the desire for bonding,' says lead author, Daniel Kruger.
The psychologists studied 456 participants and found those who fell asleep immediately had stronger desires for post-coital cuddling and chatting.
'Falling asleep before one's partner may be a non-conscious way to foreclose on any commitment conversation after sex,' says co-author Susan Hughes, associate professor of psychology at Albright College.
The study also found that despite the common stereotype that men fall asleep first, there was no significant difference between the genders.

Sex and sleep
According to Dr. Billy Goldberg, co-author of Why Do Men Fall Asleep After Sex?, there is little direct evidence explaining why men fall asleep. However, the chemicals oxytocin, prolactin, gamma amino butyric acid (GABA) and other hormones all contribute to “that roll-over-and-snore feeling” because they facilitate sleep.
“A man’s body chemistry changes after orgasm. The biochemical prolactin is released, physically altering his body and making him very tired,” says Dr. David McKenzie, a sex therapist in Vancouver, Canada.
Further, exertion during sex and after climax depletes the muscles of energy-producing glycogen, which leads to sleepiness. Since men have more muscle mass than women, they’re generally sleepier after sex.
