Who says having more sex makes people happy -- certainly not a new study from Carnegie Mellon University. It suggests that increasing your sexual activity could actually make you more miserable.
At least 128 couples took part in the study. Some couples had to double the amount of sex they would normally have in a week. The others had to reduce it. Their happiness was then tracked for three months. Those assigned to have more sex reported being a little less happy.
Researchers think it's because they were asked to do something, rather than let it happen naturally. And the more frequent sex didn't necessarily increase sexual desire or enjoyment.
