Running benefits our neck, shoulders, spine, blood circulation, liver, digestive system, and bones.
1. Eyes
Long-distance runners spend about an hour daily gazing into the distance, which provides excellent relaxation for the eyes. If you have school-age children at home, having them run daily will significantly reduce their risk of developing myopia.
Research indicates running may effectively treat certain eye conditions. In one study, mice had one eye covered. They were divided into two groups: one forced to run continuously on a wheel for hours, stimulating visual cortex neurons, while the other remained inactive.After a period, the vision of the first group fully recovered to pre-blinding levels, while the second group's vision recovered slowly and incompletely.
2. Neck, Shoulders, Spine People who frequently sit at computers often develop neck and shoulder issues. Proper running posture requires a straight, relaxed back. Consistent running significantly alleviates discomfort in the cervical spine and shoulders.
3. Heart
Consistent running builds a robust heart and cardiovascular system. It increases maximum oxygen uptake while substantially boosting oxygen delivery to all organs, naturally enhancing their functionality. Additionally, middle- and long-distance running accelerates blood circulation, ensuring adequate coronary artery blood supply to the myocardium and thereby preventing various heart diseases.Lower-body movement also promotes venous blood return to the heart and prevents blood clot formation in veins.
4. Blood
With a robust cardiovascular system, runners exhibit superior blood quality compared to non-runners. The adaptive changes occurring in the body from long-term endurance running improve metabolism and reduce blood lipid and cholesterol levels.
5. Lungs and Respiratory System
Long-term endurance running strengthens lung function and increases lung capacity—regular long-distance running develops respiratory muscles, enlarges tidal volume, and enhances overall lung performance.Personally, I used to suffer from seasonal rhinitis every autumn, but since starting running this year, it hasn't recurred. I wonder if there's a connection?
Running can increase average lung capacity from 5.8 liters to 6.2 liters, while also significantly boosting the oxygen-carrying capacity of the blood.
6. Liver
For those with fatty liver disease, the best medicine is "running." A new study shows that aerobic exercises like running can slow the progression of non-alcoholic fatty liver disease in obese individuals with prediabetes.
Researchers studied 15 obese patients with non-alcoholic fatty liver disease, having them run on a treadmill for one hour daily at 85% of their maximum heart rate.After seven consecutive days, participants showed enhanced insulin sensitivity and an 84% increase in liver polyunsaturated fat index (PUI). Researcher Haus noted these improvements correlate with elevated levels of the hormone adiponectin, which enhances insulin response, reduces inflammation, and lowers heart disease risk. Additionally, aerobic activities like running effectively burn fat and mitigate fatty liver damage.
7. Abdomen
A flat stomach or defined abdominal muscles is a dream for many. While fitness trainers' advice and viral exercises like the "ab ripper" can strengthen your core, you also need aerobic activities like running to shed the thick layer of fat covering your abs.Of course, consistency is key—abdominal fat is the most stubborn, ready to rebound at the slightest lapse.
Studies show a 30-minute steady jog burns over 390 calories, compared to 277 calories for cycling and 272 calories for tennis in the same timeframe.So if you choose the right exercise, you'll achieve your desired physique faster.
8. Waist and Hips
Running's impact on your figure first shows here. Many runners have experienced this: after running for a while, their weight doesn't drop noticeably, but their shape improves significantly—especially with a more defined waistline.
Running's advantage over other exercises lies in its dual benefits: it strengthens muscles and joints like any workout, while also keeping your metabolism elevated for up to four hours post-exercise, burning more calories.Most dedicated runners experience knee discomfort to some degree. However, conversations with fellow runners who've maintained their habit for over a decade reveal that they faced similar issues initially—some even felt knee pain during brisk walking. Yet, through gradual increases in jogging mileage and targeted strength training, their knees grew progressively stronger.
When age is factored out, numerous long-term studies indicate that runners actually have a lower risk of developing knee arthritis.
10. Leg Muscles
Regular running also transforms muscle tissue. After consistent training, you'll notice your leg muscles become remarkably firm and toned. Running enhances cardiovascular and respiratory function, promotes muscle and nerve health, and boosts the body's disease resistance.During colder winter months, sustained jogging with small strides stimulates the body's protective responses. This accelerates blood circulation, increases cerebral blood flow, and regulates the brain's thermoregulatory center.
