Expert commentary: The feet are the roots of the human body. Regular hiking can strengthen lower limb strength, improve joint flexibility, promote venous blood return in the lower limbs, and prevent diseases such as varicose veins, osteoporosis, and muscle atrophy. It can also effectively stimulate the six meridians in the lower limbs and many acupoints on the soles of the feet, ensuring smooth energy flow and delaying aging. While hiking, swinging your arms and moving your waist, back, and neck joints and muscles continuously promotes the metabolism of bodily energy and enhances heart function.
I. Health Benefits of Hiking
As an outdoor activity, hiking offers multiple physical benefits. It is both an aerobic exercise and involves elements of strength training, and its intensity and volume can be adjusted according to your own fitness level and physical condition. It can be said that hiking is a comprehensive form of exercise with relatively low risk.
1. Effects of Hiking on Muscles and Bones Regular participation in hiking has positive effects on joints, bones, and muscles. Hiking improves blood circulation in the bones, enhances bone metabolism, increases calcium and phosphorus deposition in bones, boosts bone elasticity and toughness, and helps prevent osteoporosis and delay the aging process of bones. Regular hiking also promotes protein synthesis in muscles, making them stronger and more resilient.
2. Effects of Hiking on the Nervous System Regular hiking can improve the function of the central nervous system, making you more energetic, agile, and efficient at work. Hiking improves cerebral blood supply, reduces neurological fatigue and mental tension, and enhances sleep quality.
3. Effects of Hiking on the Cardiovascular System Hiking has a clear effect in preventing cardiovascular and cerebrovascular diseases. Hiking helps remove cholesterol deposits from blood vessel walls, prevents arteriosclerosis, and reduces the incidence of cardiovascular disease. It can also increase the diameter of blood vessels, boost coronary blood flow, improve myocardial blood distribution, enhance the heart’s oxygen utilization capacity, and thus help prevent cardiovascular and cerebrovascular diseases.
4. Effects of Hiking on the Respiratory System Hiking can strengthen respiratory muscles, help maintain the elasticity of lung tissue, improve ventilation and gas exchange in the lungs, increase oxygen intake capacity, and elevate the metabolic levels of all organs. Moreover, most hiking environments are near mountains and water, with rich vegetation, fresh air, minimal pollution, and higher concentrations of negative oxygen ions. These ions can improve lung function, regulate the nervous system, uplift mood, enhance sleep, lower blood pressure, and stimulate hematopoiesis, offering calming, sedative, blood-pressure-lowering, and fatigue-reducing benefits.
5. Effects of Hiking on the Digestive System Regular hiking increases energy consumption and nutritional demands, which boosts appetite and improves digestive system function. It strengthens gastrointestinal motility, increases digestive fluid secretion, and enhances nutrient absorption.
6. Effects of Hiking on the Immune System Regular hiking improves the body’s immunity, reducing the likelihood of catching colds and illnesses such as tonsillitis, pharyngitis, tracheitis, and pneumonia that may follow. It also helps prevent complications like emphysema and pulmonary heart disease resulting from tracheitis.
7. Weight Loss Effects of Hiking The basic principle of weight loss is burning more calories than you consume. Exercise is the primary channel for calorie expenditure, but not all exercises yield ideal weight-loss results. The best forms of exercise for weight loss are those of low intensity, which, due to ample oxygen supply and long duration, result in high total calorie burn. Hiking is precisely such a moderate-intensity, long-duration activity, giving it unique advantages for weight loss.
8. Effects of Hiking on Mental Health Hiking gives you a sense of returning to and connecting with nature, helping shift mental stress from daily work. Towering peaks and winding trails test your physical stamina and willpower. Regular hiking builds self-confidence, helps overcome negative moods, and leads to better mental and psychological health.
II. Physical Reactions After Hiking
Many people who don’t exercise regularly often feel discomfort after hiking, with the most common reaction being delayed-onset muscle soreness. This is an overuse injury typically occurring 24–48 hours after unfamiliar exercise. Its main symptom is muscle pain, which generally lasts around three days before disappearing. Apart from soreness, it usually doesn’t harm the body. Women who rarely exercise—even those who are otherwise active but don’t hike often—may experience varying degrees of muscle soreness after hiking. For beginners, it’s advisable to start with low-intensity hikes and gradually increase intensity to allow the body to adapt.
