There are many benefits to going for a spring outing. For example, walking through forests and streams to breathe fresh air can clear the lungs and strengthen the spleen, enhancing cardiopulmonary function; climbing peaks and crossing ridges can relax muscles and tendons, prevent joint aging; brisk walking can promote blood circulation and prevent arteriosclerosis; stopping to gaze into the distance can broaden one's horizons and bring peace of mind; and by burning calories, it can promote gastrointestinal motility, improve digestive function, and increase appetite, among other benefits.
In the pleasant climate of spring, the air is rich in "longevity factors"—negative oxygen ions. According to measurements, in a room in a big city, there are only 40 to 50 negative oxygen ions per cubic centimeter of air, while in the countryside, there are 700 to 1,000, and at the seaside and in valleys, it can exceed 2,000, which is greatly beneficial to human health. It can not only kill various bacteria in the air but also regulate brain function, promote blood circulation and metabolism, enhance the body's resistance, eliminate fatigue, and invigorate the spirit. It also has effects such as relieving pain, calming the nerves, and reducing cough, asthma, and blood pressure, and is therapeutic for hypertension, asthma, neurasthenia, and arthritis. Therefore, it is also known as the "vitamin of the air."
Additionally, the gentle spring breeze and suitable light in the wild create a very comfortable feeling, and the fatigue from stressful work will dissipate. Furthermore, it can slow down a person's heart rate and breathing, allowing the heart and lungs to rest. Some studies have shown that in the wild, the heart beats 4 to 8 times less per minute than in the city, and in some cases, it can be 14 to 18 beats less, with breathing reduced by 2 to 3 times. This is extremely beneficial for the heart and lungs.
The green mountains and clear waters also provide a visual impact that is greatly beneficial to your vision. Being surrounded by mountains and water, looking out into the distance, will relax the ciliary muscles inside the eyes and the eye's refractive adjustment mechanism, preventing myopia. Green is also a benign stimulus for the eyes, which can make vision sharper and the mind calm.
For the elderly who have been cooped up indoors all winter, going for a spring outing is an excellent choice. You can stroll and tour, regulate your nerves, and improve the excitation and inhibition processes in the cerebral cortex. At the same time, it can also cultivate your temperament and strengthen your body.
