John Cena and his WWE opponents might epitomize the macho mayhem testosterone is supposed to create. But that mostly male hormone (gals have 5 percent to 10 percent of guys' levels) fosters more than posturing and aggression. It's important for sexual desire and satisfaction, brain size and function, muscle tone -- and, surprisingly, honesty. Yes, it's true!
A recent study found that men dosed with a bit of extra testosterone lied less frequently than those without the hormone helper. (One or two lies a day is average, but half of all lies are told by only 5 percent of you!)
Why does testosterone reduce lying? Seems the hormone works in the brain to promote ethical behavior and feelings of social cooperation, possibly by reducing fear, making you more resilient to stress and more self-confident. So, guys, young or old, peace-loving or not so much, there are many benefits from making sure you have a good supply of the juice you need to stay healthy and honest. Here's how you can naturally boost your testosterone levels:
1. Lower your BMI (body mass index). Every two-point drop in BMI (about 12 excess pounds in a guy 5 feet 9 inches tall) increases circulating testosterone by a corresponding two points.
2. Reduce your alcohol intake: Daily moderate drinking can lower levels by 7 percent.
3. Relax with meditation, mindfulness or aerobic exercise. Stress increases fat deposits that turn testosterone into estrogen (really!).
4. Sleep seven to eight hours a night, every night. Deep REM sleep is when most testosterone is made. Sweet dreams, indeed!
