Poor Sleep Associated with Lower Testosterone Levels.

If your sleep quality is poor, you might be more likely to experience reductions in testosterone, recent research suggests. Investigators reviewed data on 9,756 participants in a national health survey, including 2,672 men who had their testosterone measured. The participants also were queried about their body mass index (BMI, a measurement of obesity) and their sleep habits, reporting that they slept about two to 12 hours a day (mean sleep duration, 6.9 hours). After the researchers adjusted for other factors, they found that each hour of lost sleep and each unit increase in BMI were associated with a decline in testosterone levels. "It is important, therefore, that evaluations of reduced testosterone levels should focus on diet, exercise as well as sleep quality and habits," the study authors noted (American Urological Association Annual Scientific Meeting, May 2018). The take-home message: Poor sleep quality, as well as increases in BMI, are linked to reductions in testosterone. (To calculate your BMI, divide your weight in pounds by your height in inches squared and multiply by a factor of 703. A BMI of 18.5 to 24.9 is healthy, 25 to 29.9 is overweight, and 30 or more is obese.) Optimize your weight with a healthful diet and exercise. Discuss any sleep problems you have with your physician, and follow his or her treatment recommendations.
