For those who like a firm sleep surface, sleeping on the floor seems ideal. Lots of people have already made a cold, flat floor part of their night-time routine. In fact, in some cultures, it's more common to sleep on the floor than on a thick mattress. If you're new to the sleeping-on-the-floor phenomenon, it's crucial to know what's best for your back.
There is anecdotal evidence that sleeping on the floor can help with back pain, spinal alignment, and temperature regulation, but there is little scientific research, and resting on such a solid surface could have the opposite effect. Depending on what you're used to, sleeping directly on the floor can be a big adjustment, and your back could pay the price.
