Here’s what you’ll learn when you read this story:While you might start the day with a shower, studies have shown that a warm bath or shower before bed can actually help you fall asleep faster—and stay that way for longer. Taking a long bath for 30 minutes is the most beneficial for sleep quality and efficiency, but short baths or showers that are about 10 minutes long can still help. It takes most people 10 to 20 minutes to fall asleep. Sleep latency is also related to sleep efficiency, or the percentage of time someone is actually asleep while in bed. It turns out that taking a long bath that lasted about 30 minutes had the most positive effects.
