To maintain a healthy level of Testosterone you should :-
Get Enough Sleep.
Poor sleep is the most important factor. A lack of sleep affects a variety of hormones and chemicals in your body. This can have a harmful impact on your testosterone. Sleep for seven to eight hours per night, avoid late-night TV and other harmful habits.
Maintain Healthy Weight.
Men who are overweight or obese often have low testosterone levels. Losing the extra weight can help bring testosterone back up. Likewise, for men who are underweight, getting your weight up to a healthy level can also have a positive effect on the hormone levels.
Exercise is must.
Testosterone adapts to your body's needs. If you spend most of your time lying on the couch, your brain gets the message that you don't need as much to bolster your muscles and bones, but when you are physically active, your brain sends out the signal for more production of the hormone. But remember too much endurance can actually lower your testosterone levels.
Take Control of Your Stress.
If you're under constant stress, your body will release out the stress hormone cortisol. Cortisol is antagonist of testosterone, so the testosterone level will drop. So, controlling your stress is important for keeping up your testosterone. Yoga, Music and Meditation are pretty helpful in relieving stress. Try out any of these.
Review Your Medications.
Some medicines can cause a drop in your testosterone level. These drugs include-
Opioid drugs such as fentanyl, MS Contin, and OxyContin.
Glucocorticoid drugs such as prednisons.
Anabolic steroids used for building muscles and improving athletic performance.
You shouldn’t stop taking any of your medications. If you're concerned about your testosterone level, discuss your medications with your doctor to make sure they're not the problem and to make adjustments to your treatment if needed.
No need of Testosterone Supplements.
Finally, although you're likely to encounter online ads for testosterone-boosting supplements, you aren't likely to find any that will do much good. Your body naturally makes a hormone called DHEA that it can convert to testosterone. DHEA is also available in supplement form. But they will do little to actually raise your testosterone.
