Entertainment and Leisure and Biological Rhythms: Analyzing the Longevity Benefits of Music, the Miraculous Effects of Hot Foot Baths, and the Rules of Adhering to the Biological Clock [i]

Entertainment-based health preservation refers to using relaxed, enjoyable, and diverse activities to soothe the mind, strengthen muscles and bones, and improve blood circulation.[i] Entertainment activities provide aesthetic enjoyment, and a smooth emotional state leads to unobstructed flow of energy throughout the body.[i] Many successful people understand the importance of entertainment-based health preservation; President Truman enjoyed playing the piano, and President Roosevelt spent 10 minutes reading poetry every day.[i] Practicing calligraphy requires calmness and concentration, with the head upright and the body straight, and its function is similar to that of Tai Chi.[i] However, entertainment must be harmonious and moderate, and one should not become addicted.[i] Use a happy mood to regulate one's mind and use good hobbies to nourish one's vital energy.[i] Washing feet with hot water is an important part of traditional Chinese medicine health preservation.[i] As the proverb says, "Washing feet in winter warms the lower abdomen."[i] The soles of the feet are the windows to the body, and the five internal organs have projection areas on the feet, such as the projection area of ​​the genitals on the heel and the projection area of ​​the kidneys on the Yongquan acupoint.[i] "A person's feet are like a tree's roots; when a tree withers, the roots dry up first, and when a person ages, the feet weaken first."[i] The Kidney Meridian of Foot-Shaoyin is located on the sole of the foot, and the fat layer on the foot is thin, making it most susceptible to cold [i]. Pressing the Yongquan acupoint while washing feet with hot water can eliminate the heaviness in the lower limbs and fatigue throughout the body, promote sleep, and strengthen the body [i]. Soaking feet in hot water can prevent and treat diseases: (1) People with headaches can be significantly relieved by soaking their feet for 15-20 minutes, because hot water dilates the blood vessels in the feet and reduces cerebral congestion [i]. (2) Pressing the Yongquan and Taichong acupoints helps lower blood pressure [i]. (3) Long-term adherence can prevent rheumatism, insomnia, and colds [i]. (4) Soaking feet in winter can prevent frostbite [i]. The water temperature should be controlled according to the season: no more than 45℃ in winter and around 50℃ in summer [i]. Scientific research has confirmed that everyone has a natural rhythm in their body, such as physical strength, mood, and blood pressure, which is the biological clock [i]. Human physiological indicators such as body temperature, pulse, and brain waves will change periodically with the changes of day and night [i]. Humans' biological clocks often have relatively fixed rhythms. Following a regular lifestyle ensures the most stable physiological metabolism and the greatest energy conservation [i]. Irregular lifestyles can easily disrupt metabolism, potentially shortening lifespan by about 10% [i]. ★Optimal times of day: (1) 3 minutes after a meal is the best time to rinse and brush your teeth [i]. (2) The best time to drink tea for health is 1 hour after a meal [i]. (3) The best time to eat fruit is 1 hour before a meal [i]. (4) The best time to sunbathe is from 8:00 AM to 10:00 AM [i]. (5) The best time to take a walk is 45 to 60 minutes after a meal [i]. (6) The best time to take a bath is before going to bed at night [i]. (7) The best time to exercise is in the evening [i]. As people age, their biological clocks become more fixed and less adaptable, making regular lifestyles even more important [i]. Only by respecting natural rhythms and harmonizing life's rhythms can one prolong life [i]. [i]
