A third of women have experienced post-sex blues at some point, an Australian study shows, but researchers don't understand why. The period immediately after sex normally results in feelings of wellbeing, and mental and physical relaxation. But the study of more than 200 young women reveals many have experienced the reverse.

Queensland University of Technology Associate Professor Robert Schweitzer, who did the research, said 32.9 per cent of respondents had experienced the phenomenon at some point.

That was despite the sexual interaction being otherwise satisfactory.
