However, a good night's sleep and a wholesome meal the next day can fix it. After all, we all need a break to unwind and recharge our batteries from time to time. But if you're finding yourself exhausted day in and day out, for weeks in a row, and nothing helps to restore your regular energy, there may be a more serious cause that requires medical attention.

What causes your low energy?

Low testosterone. The primary male sex hormone, testosterone is responsible for a slew of different health aspects, from sex drive to muscle mass and bone density. It's a fact that testosterone levels decline with age. In case of a significant drop, men may experience more pronounced symptoms of low testosterone, such as increased body fat, lagging libido, decreased motivation, and sleeping troubles, cumulatively resulting in chronic fatigue. If you experience any of the above, your first step should be to check your hormone profile through a blood test to see if it's low T causing your tiredness. (Boost your testosterone naturally.)
