There’s a reason so many of us keep our sex toys in our nightstands; having an orgasm is an essential part of many people’s pre-bed routines — and for good reason. According to Laura Purdy, MD, chief medical officer at Wisp, “Both partnered and solo sex can improve your chances of falling and staying asleep.” That’s because studies report that the hormones released post-orgasm help reduce cortisol (or the hormone that causes stress), making you feel more relaxed and leading to better sleep quality. Oh, and it can also make you fall asleep faster. If that’s not enough of a reason to start using a sex toy before bed, how about this: Everyone’s favorite one-stop-shop retailer, Amazon, is filled with a bounty of motorized goodies that will have you raving (and then snoozing) in no time.
