Showering Before Bed - Is It a Good or a Bad Idea?

So, how does this relate to showering? When you take a warm bath or shower, you’ll aid in the process of regulating the ideal temperature for sleep. While you may get a temporary spike when you’re in the warm water, your body will cool down as soon as you leave the water and towel off. If your shower was too hot though, you might need to give yourself about 60 to 90 minutes to cool down after.
