A warm bath isn’t just clean, it’s sleep-inducing, says everyone who loves this alone-time ritual. We’ve ranked the best bath salts for sleep, to help you slumber faster.

But Do Hot Baths Really Help You Fall Asleep?

According to a published review of thousands of sleep studies, yes. Herewith, the deets: The optimum bath regimen to encourage sleep is a bath that’s 104 to 108.5 degrees and lasts at least 10 minutes. And you need to take the plunge one to two hours before bedtime. This hot soak actually helps you fall asleep faster than taking no bath at all, because what actually helps you fall asleep is (major twist)—the body’s cooling mechanism. Because a hot bath raises our core temperature, so when you get out of the bath, your body will cools down and you’re getting sleepy, very sleepy.

What Are Bath Salt Ingredients to Look For?

Since hot water is just the beginning, a fragrant, herbal or otherwise therapeutic bath salt will enhance your bathing experience. Look for soothing herbs like lavender, heady essential oils like rose and moisturizing ingredients including clay. And CBD-infused salts are popular for sedating, but non-psychoactive, chill.
