The hazards of walking for a long time often include weakness in the limbs, joint pain, muscle pain, and so on. 1. Weakness of the limbs: walking for a long time can easily lead to obvious fatigue, often manifested as weakness of the limbs after excessive exercise. 2. Joint pain: When walking excessively, the tendons of the feet are in a tense state for a long time, which can easily lead to muscle strain and cause joint pain. 3. Muscle pain: If you don’t get timely rest on the way, walking for a long time will easily cause soft tissue strains and obvious muscle pain. Walking as a daily exercise, reasonable exercise is conducive to cardiorespiratory fitness, but if you continue to walk for a long time without proper rest, the above mentioned hazards will also occur. It is recommended to take care not to overdo it when walking and to arrange rest time appropriately.
