The best time to put on your compression stockings is in the morning, when your legs are the least swollen. When you sleep, your legs are horizontal and thus gravity does not affect them. As you begin your day, gravity affects your legs and they begin to swell. As the day progresses, the swelling becomes more pronounced and your legs are the most swollen at the end of the day. Therefore, the two main reasons why you should put on compression stockings in the morning are, because it prevents the swelling that occurs later throughout the day and because it’s a better fit.
Please do not wear compression stockings to bed, unless your doctor instructs you to do so.
