Take a bath 90 minutes before bedtime to get better sleep

Biomedical engineers at The University of Texas at Austin may have found a way for people to get better shuteye. Systematic review protocols—a method used to search for and analyze relevant data—allowed researchers to analyze thousands of studies linking water-based passive body heating, or bathing and showering with warm/hot water, with improved sleep quality. Researchers in the Cockrell School of Engineering found that bathing 1-2 hours before bedtime in water of about 104-109 degrees Fahrenheit can significantly improve your sleep.
