Maybe you sleep in a nightgown, or an ex’s ragged T-shirt or a la odalisque. (Nude, with an ostrich feather covering your sensitive bits.) But you can still add pajamas into the mix. They will help signal to you mentally that you’re beginning to wind down for the night, even if you aren’t doing any of that other stuff you’re supposed to do before bed, such as not looking at your phone, abstaining from alcohol and caffeine, or avoiding staring at social media, wondering why your dog isn’t as cute as your ex’s dog.

Put them on after dinner, or even after work, to announce to yourself and your loved ones that you’re really off the clock. (This is the kind of thing a butler or valet might do, but a pair of pajamas is much more cost-effective and machine-washable.)
