Fishing can eliminate anxiety, balance mentality and relieve "heart and spleen dryness and heat". Modern medicine defines physiological, psychological and environmental factors as the mechanism of human diseases. Fishing has "resistance, control and prevention" effects on these three pathogenic mechanisms.
Fishing can improve people's physical function. On the beautiful shores of rivers, lakes and seas, the air contains a large number of negatively charged macromolecules-negative ions. After negative ions are inhaled into human body, negative ion effect can be produced. That is to say, this negative ion can combine with hemoglobin and positive ions such as potassium, sodium and magnesium in the body, so that the oxygen in the blood is increased and the nutrients carried are increased, and people will feel more comfortable and energetic. Fishing is ostensibly killing time, but in fact it is saving your energy. When you return to work, you will get twice the result with half the effort.
Fishing can regulate the function of the central nervous system. Fishing gradually forms an "exciting focus" in the angler's cerebral cortex by loading bait, throwing rod and standing still until the fish bites the hook. Russian physiologist Pavlov once said that the advanced part of the central nervous system-the cerebral cortex and its nearest subcortical nucleus-plays a leading role in various functions of the body. The benign stimulation process of fishing is also a process of adjusting the balance of the central nervous system, so as to achieve the purpose of treating diseases and strengthening the body.
Regular fishing activities have therapeutic and auxiliary effects on scapulohumeral periarthritis, cervical spondylosis, bronchitis, emphysema, peptic ulcer, chronic gastritis, dyspepsia, neurosis, habitual constipation, chronic hepatitis, hypertension and coronary insufficiency.
