Do physical exercises need good sleep for recovery? What is its theory? Yes, good sleep is essential for recovery after physical exercise. The theory behind this lies in the body's natural repair processes during deep sleep, where growth hormone production increases, aiding muscle recovery, tissue repair, and energy restoration. Sleep also helps regulate cortisol levels, reducing inflammation and preventing overtraining-related fatigue. Without adequate sleep, muscle recovery slows down, leading to decreased performance, increased injury risk, and prolonged soreness. To maximize fitness results, prioritize quality sleep, proper nutrition, and stress management. If sleep issues affect your recovery, consulting a mental health expert can be beneficial.
