We get this question all the time, or it's cousin "Can I wear compression socks to bed?"
The answer is yes... if you're one of those people who can sleep with sock on.
Seriously, there is no downside to compression socks while sleeping - they keep your circulation up and help to speed up your recovery even while you're sleeping.
The key is to find some lightweight compression socks that still have a good amount of compression so you don't feel the 'squeeze' all night long. You're looking to aid your sleep, not prevent yourself from sleeping after all.
We would also recommend that you reduce the number of blankets that you sleep with on nights that you wear compression socks to bed - even light socks are going to keep body heat in, which will keep you warmer throughout the night.
Our last suggestion is not to try sleeping with compression socks for the first time the night before something important - for some people there is a bit of an adjustment process and the last thing you want is for your recovery plan to backfire and reduce the recovery and sleep for your big event/race. Trust us on this one.
