Because muscles have such a hard task. The only muscle in your body that does not get tired is your cardiac muscle also known as your HEART
The heart
Lactic acid causes muscle fatigue because it accumulates in muscles during intense exercise, leading to a decrease in pH levels. This decrease in pH interferes with muscle contractions and energy production, ultimately causing the muscles to feel tired and fatigued.
When a muscle is exercised, lactic acid is formed in the muscle, and that is what makes the muscle feel tired. With a short rest, the lactic acid is carried away by the blood stream and the tired feeling goes away.
A flexor is a muscle that causes a joint to bend. In contrast, an extension is a muscle that straightens a joint.
Dull and tired-looking skin can result from a combination of lifestyle, environmental, and physiological factors. Common causes include dehydration, lack of sleep, poor nutrition, and excessive exposure to pollutants or UV radiation. These factors can impair skin cell turnover, reduce blood circulation, and lead to the buildup of dead skin cells, making the complexion appear lackluster. Stress and inadequate skin care routines also contribute by disrupting the skin’s natural barrier function. Additionally, age-related decline in collagen and elastin can reduce skin vitality. Hormonal imbalances and certain medical conditions may further impact skin tone and texture. Dr Megha Modi emphasizes that understanding the root cause is essential for effective management. At Twachaa Clinic, dermatological evaluations consider both intrinsic and extrinsic factors affecting skin health. For individuals experiencing persistent skin dullness, adopting healthy lifestyle habits and appropriate skincare can help restore radiance. Consult a doctor for personalized assessment and guidance tailored to your specific needs.

Your cardiac muscle is also a lot stronger than you skeletal muscle.Sorry, also your heart is an involuntary muscle. We have no control over it. Whereas skeletal muscles are voluntary, we decide to move them or not.
