Sex Before Bed Can Nearly Double Your REM Sleep, Study Reveals
REM sleep (Rapid Eye Movement) is seen as the most important stage of our sleep cycle as it stimulates areas of the brain essential for learning and memory. REM should make up around 23% of our sleep.
Intrigued to find out if sex can impact sleep cycles, experts at TheDozyOwl.co.uk conducted a study looking into the impact of different sex positions on our REM sleep. 1,652 participants were asked to wear a sleep monitor to bed after having sex in one designated position. Participants tried out each of the chosen twenty-five popular positions over a three month period, revealing the sex positions that improve our REM sleep the most.*
Sex Positions that Increase REM the Most:
TheDozyOwl.co.uk found that having sex before bed can increase REM sleep by an average of 8%, with men seeing a 12% average increase, whilst women only see a 2% average increase. Alex Ion, expert at TheDozyOwl.co.uk contributes this to “women being more mentally stimulated during intercourse than men who are more physically stimulated. Women, are therefore more likely to be alert after sex, whereas men are typically tired after ejaculation.”
