Living a Healthy Lifestyle but Still Feeling Tired? Expert Explains Why

Eating healthy and exercising but still exhausted? Discover the hidden reasons behind your fatigue as an expert explains why you're always tired. 

Fatigue is a state of weariness that drains an individual’s physical energy, mental focus, and motivation. Sometimes they go away after resting. However, there are times when fatigue becomes regular, and even rest cannot undo it. People often complain that they feel fatigued all the time, despite following a healthy lifestyle. There can be various reasons behind this. Today, this article will explain it to you.

To understand this better, we reached out to Dr Pooja Pillai, Consultant Internal Medicine, Aster CMI Hospital, Bangalore.

Why Do People Feel Fatigued Despite a Healthy Lifestyle?

Dr Pillai says that some people may still feel tired even after following a healthy lifestyle. Explaining the reason, she says, “This is because fatigue can have many hidden causes beyond diet and exercise.” She adds that common reasons include: 

  • Poor quality sleep
  • Stress
  • Anxiety
  • Dehydration
  • Vitamin deficiencies such as low iron, Vitamin D, or Vitamin B12
  • Hormonal imbalances such as thyroid disorders 

The expert continues, “Certain medical conditions such as diabetes, anaemia, sleep apnoea, infections, or heart problems can also cause ongoing tiredness. In some cases, over-exercising without proper rest may leave the body exhausted instead of refreshed.”
