Wearing socks in bed is a big turn off for some, while others can't sleep without socks on. Research by the National Sleep Foundation shows that the latter group probably has a point:wearing socks in bed makes you fall asleep faster.
If you have trouble falling asleep, it pays to put on socks. When your feet are warmed by socks, your blood vessels expand. Vasodilation ensures that the heat is distributed throughout your body and that signals your brain that it is bedtime.
Sex with socks on also seems to be a good idea.
