Why Do I Always Feel Muscle Soreness the Day After Exercise?

Post-exercise muscle soreness
During exercise, the human body secretes a component called lactate, and it accumulates in the muscles, stimulating nerve endings and causing muscle soreness.
Have you ever experienced this? After intense exercise, muscles become very stiff, and they hurt even with gentle touch. This is because of delayed muscle soreness. The pain is caused by the small tears in muscle fibers that occur when muscles are overstretched during exercise.
Why does muscle pain always occur the day after exercise? This is because at the site of muscle fiber tears, the muscles become inflamed, and water accumulates around the inflamed muscles. This process can last for several hours, or even a whole day. The accumulated water causes the inflamed area (i.e., overworked muscles) to swell and harden, until then we can feel the pain!
Small suggestions
If you want to relieve muscle soreness, you should first do warm-up exercises before exercise, then take a hot bath or massage at home to deeply relax the muscles. Finally, drink beverages that soothe muscle soreness.
