What is fatigue?
Fatigue is defined as an overwhelming sense of tiredness, lack of energy, and feeling of exhaustion. It can have both physical and mental components. Fatigue can negatively impact one's ability to carry out daily activities and function normally.
There are several potential causes of fatigue:
- Lack of sleep - Not getting enough sleep or enough quality sleep can lead to next-day fatigue. Most adults need 7-9 hours of sleep per night.
- Poor nutrition - Inadequate intake of nutrients, vitamins, minerals can cause low energy levels. Things like iron deficiency or vitamin D deficiency are common culprits.
- Dehydration - Not drinking enough water every day can zap one's energy. We lose water through sweat, urine, breathing.
- Stress - High stress levels cause fatigue by releasing hormones like cortisol into the bloodstream, which disrupt normal bodily processes.
- Depression - The lack of motivation and feelings of exhaustion from depression can mimic physical fatigue.
- Chronic diseases - Conditions like anemia, diabetes, and thyroid disorders directly cause fatigue.
- Medications - Certain prescription or over-the-counter drugs can list fatigue as a side effect.
- Overexertion - Pushing your body too hard through intense physical or mental activities can drain you.
Some key signs of fatigue include:
- Constant tiredness

Here are some ways to combat fatigue:

In summary, fatigue is the body and brain signaling its need for rest and recovery.
