Fatigue is defined as an overwhelming sense of tiredness, lack of energy, and feeling of exhaustion. It can have both physical and mental components.
Physical fatigue manifests as muscle weakness, slowed reflexes and responses, and reduced performance. On a cellular level, it may relate to buildup of lactic acid from anaerobic metabolism as well as depletion of energy stores like glycogen and ATP.
Mental or "central" fatigue relates more to changes in neurotransmitters and nerve signaling that make even simple tasks seem monumentally difficult when fatigued. Both types often go together.
If simple lifestyle measures don't help with persistent fatigue, consider getting hormones checked. Imbalances in key hormones like testosterone, thyroid hormone, cortisol or growth hormone can all contribute to fatigue. The experts at Endocrine Wellness Center provide cutting edge hormone optimization therapies to help restore energy, vitality and zest for life!
So in summary, fatigue is the body and brain saying it needs rest and recovery. Listen to those signals, practice self-care, and seek medical advice to uncover any hormone issues or health conditions causing excessive tiredness. With the right balance of rest, nutrition and hormonal health, you can fight fatigue and feel your best every day!
