Tiredness is a common complaint, but constant fatigue and low energy in men isn’t something to overlook. When fatigue lingers for weeks or months,
it can signal deeper health issues, physical, mental, or even hormonal. In today’s fast-paced world, more men report feeling perpetually exhausted, and this isn’t just about working too hard or not sleeping enough.
Let’s explore the real reasons behind this energy drain, backed by science, and provide clear strategies to recharge your system and regain control of your health.
Common Causes of Constant Fatigue and Low Energy in Men
1. Hormonal Imbalances (Low Testosterone)
Testosterone is a key hormone in men responsible for muscle mass, energy, libido, and mood. Low testosterone, or Low T, can lead to constant fatigue and low energy in men.
According to the American Urological Association, testosterone levels decline about 1% per year after age 30, and this drop can lead to chronic tiredness, depression, and decreased motivation.
Signs of low testosterone include:
- Poor sleep quality
- Mood swings
- Reduced libido
- Increased body fat

2. Sleep Disorders
Sleep apnea, insomnia, and restless leg syndrome can prevent men from getting deep, restorative sleep. Even if you’re sleeping 7–8 hours, poor sleep quality may leave you feeling exhausted.
A study published in the Journal of Clinical Sleep Medicine found that 25% of men with sleep apnea experienced excessive daytime fatigue.

3. Nutritional Deficiencies
According to a research study by M. Świątczak, K. Młodziński, K. Sikorska, and A. Raczak, a lack of essential nutrients, such as iron, vitamin B12, and magnesium, can cause chronic fatigue. Iron-deficiency anemia, in particular, is often underdiagnosed in men.
Without sufficient nutrients, the body struggles to produce enough healthy red blood cells, resulting in a reduced oxygen supply to muscles and organs, leading to fatigue.

4. Chronic Stress and Mental Health Issues
Long-term stress activates the body’s “fight or flight” response and increases cortisol levels, which can eventually deplete energy reserves.
Depression and anxiety are also major culprits. The National Institute of Mental Health reports that millions of men suffer silently from depression, often presenting it as irritability or exhaustion rather than sadness.

5. Lack of Physical Activity
According to a research study by W. Ament, GJ. Verkerke, ironically, while fatigue may reduce the desire to exercise, a sedentary lifestyle can worsen tiredness. Regular movement improves circulation, boosts endorphins, and increases energy levels.
