A Study Suggests the Less You Sleep, the Less People Like You

You probably don’t really care if your friends look tired because you love them just as they are. You might worry about their health, but it’s unlikely it will significantly affect how much you want to spend time with them. However, when you don’t really know someone, their appearance plays a huge role in whether you’ll interact with them or not. So if they look very sleepy, you might feel like you’d rather avoid them.
