Kegel exercises for middle-aged men to prevent disease, seasonal exercise adjustments, and running safety guidelines

139. How to prevent and treat anal diseases using Kegel exercises? Kegel exercises can be performed while sitting, lying down, or standing. The method is as follows: Concentrate your mind, contract your abdomen, and slowly exhale while consciously contracting your anus upwards. Once you have exhaled as much air as possible from your lungs, hold your breath and maintain the contraction for 2-3 seconds. Then relax your whole body, allowing air to naturally enter your lungs. Rest for 2-3 seconds, and repeat the above movements. Perform this 1-2 times daily, 30 repetitions or 5 minutes each time. Avoid rushing the exercise; aim for a comfortable feeling. The key is to persevere.

Why should fitness exercises be adjusted according to climate changes? Nature is an essential condition for human survival. Humans cannot live without nature, and to maintain normal life activities, they must adapt to it; otherwise, they will fall ill and shorten their lifespan. The four seasons of spring, summer, autumn, and winter bring cold, heat, dryness, and humidity, thus affecting all things in nature. Therefore, exercise must also be in harmony with the natural environment. With seasonal climate changes, middle-aged men should also make corresponding adjustments to their exercise methods, content, time, and intensity to achieve their fitness goals. In spring, all things revive, full of vitality. During this season, it is advisable to get up early and exercise outdoors; long-distance running remains a suitable activity. In early spring, as temperatures gradually rise, the climate becomes unpredictable, fluctuating between cold and hot. Pay attention to clothing before and after exercise; do not remove layers at the beginning, and change sweaty underwear promptly after exercise to prevent catching a cold. In summer, the weather is hot, and temperatures rise, causing a series of changes in human physiological activities. During this period, avoid exercising under strong sunlight. Exercise time and intensity can be appropriately reduced. Activities like long-distance running and soccer can be postponed. Take precautions against heatstroke during exercise, and drink a moderate amount of slightly salted water afterward. Swimming is the most suitable activity in summer, but it's best to schedule it before 10 am or after 4 pm. In autumn, mornings and evenings gradually cool down. Maintaining an early bedtime and early rising routine is important, as both are good times for exercise. All sports (including swimming) can be done during this season. As autumn deepens and the temperature rises, exercise time and intensity can be gradually increased. After the White Dew solar term, the mornings and evenings become even cooler; avoid exercising naked to prevent cold air from entering the body. Winter is the coldest season, a time of dormancy and growth. During this time, exercise requires willpower to overcome the cold; continue outdoor exercise and do not stop. Perform thorough warm-up exercises before exercise to prevent stiffness in joints and muscles. Long-distance running, ice or snow sports, and soccer are all suitable activities. Exercise time should be longer and intensity higher. However, to prevent frostbite, change your underwear promptly after sweating from exercise. It's best not to exercise too early in the morning; wait until after sunrise. The reason for paying attention to seasonal changes in exercise is, according to traditional Chinese medicine, to emphasize that the body must adapt to the changing yin and yang of the seasons. In exercise, one must both strengthen the body and avoid external pathogens to achieve the goal of improving health.

Why should you pay attention to your water intake after exercise? Drinking a large amount of water at once after exercise can cause stomach bloating, upper abdominal distension, and restricted breathing. When the water enters the liver, it can cause a large amount of fluid accumulation, leading to temporary hepatomegaly and sometimes liver pain. Excessive water in the blood, while increasing blood volume, lowers blood concentration and reduces the number of red blood cells per unit volume, thus reducing the amount of oxygen and nutrients carried. Simultaneously, increased blood flow increases the burden on the heart. Increased body water content leads to increased urine output and perspiration. Excessive urination and sweating reduce sodium chloride levels, decreasing the body's ability to retain water and reducing the nerves' responsiveness to stimuli, resulting in fatigue and weakness. Furthermore, it can cause increasing thirst, and in severe cases, leg muscle cramps. Therefore, middle-aged men should drink small amounts of water frequently after exercise, adding a suitable amount of salt to the water. Of course, it's okay to drink some cool boiled water or refreshing beverages after exercise, because these drinks can be absorbed in the stomach without digestion and stay in the stomach for a short time (about 10 minutes). However, you should never drink too much, as drinking too much is also not good for digestion.

Why is it important to engage in appropriate outdoor exercise in winter? "Life lies in movement," and appropriate physical activity has a positive effect on promoting human health. In winter, outdoor physical activity for middle-aged men can enhance their body's ability to withstand cold. When the temperature changes, the body can actively adapt to the environment, promptly mobilizing heat production functions to maintain a constant body temperature and improve its ability to resist cold. Furthermore, outdoor exercise in winter can enhance the body's disease resistance. If one stays indoors for extended periods, over time, they will lack the ability to adapt to cold environments, and as a result, they may easily catch a cold or fall ill if they are not careful when going outdoors.

Why shouldn't you rest immediately after running? Some middle-aged men experience dizziness, paleness, and cyanosis of the lips immediately after running, and in severe cases, they even faint. This phenomenon is called "orthostatic hypotension" in exercise physiology. Why does orthostatic hypotension occur? During running, the lower limb muscles undergo strong contractions and relaxations, consuming a large amount of oxygen and nutrients. To continuously replenish these oxygen and nutrients, the heart rate and blood flow need to increase to deliver more oxygen and nutrients. If you stop immediately after running, the small veins in the muscles simultaneously lose their rhythmic compression, causing a large amount of blood to temporarily pool in the lower limb muscles. This significantly reduces the amount of blood returning to the heart, leading to a drop in blood pressure and temporary cerebral ischemia and hypoxia, resulting in dizziness. This is the physiological reason for orthostatic hypotension. Therefore, when you reach the finish line, never stop immediately, and certainly don't sit down. Continue jogging slowly for a while, then walk for a while, incorporating some upper limb stretching and deep breathing exercises, before gradually stopping.

Why do I experience muscle soreness after starting to run? Initially, I often experience muscle soreness after running, especially in my lower limbs. Some people find it difficult to walk, and climbing stairs is even worse. This soreness is usually most severe the day after exercise and can last for 5-6 days. This phenomenon is not due to muscle damage, but rather a normal occurrence. There are currently two different viewpoints regarding the cause of muscle soreness: One is that insufficient oxygen supply to the muscles during exercise leads to a large accumulation of lactic acid, stimulating the muscles and causing soreness. The second is that the soreness is not caused by lactic acid, but rather by the intense contraction and repeated stretching of the muscles during exercise, causing them to remain in a contracted state afterward. Due to decreased muscle extensibility, elasticity, and contractile force, the muscles become tense and stiff, resulting in soreness. Regardless of the viewpoint, both agree that performing relaxation activities, especially stretching exercises, can help alleviate muscle soreness. Do not stop running! You must use willpower to overcome the soreness and continue running for a few more days; it will disappear naturally. If you stop running and rest for a few days until the soreness disappears before resuming running, the soreness will recur.

Why is outdoor exercise not advisable in foggy weather? Fog is mainly composed of tiny water droplets, which also contain dissolved toxic chemicals such as acids, alkalis, salts, oxides, benzene, phenols, and amines. In particular, smoke from industrial chimneys and vehicle exhaust can form acid fog and photochemical smog in some areas. Moreover, this type of fog is difficult to dissipate, making it a breeding ground for bacteria and viruses. Therefore, when people run, walk, or engage in other physical activities in fog, they are naturally affected by the pollutants, which can irritate or damage the respiratory organs and even cause diseases such as emphysema and lung cancer. Exercising in polluted fog can cause pharyngitis, bronchitis, conjunctivitis, and allergic diseases. Furthermore, exercising in morning fog, due to the high humidity, hinders the exchange of oxygen and carbon dioxide in the alveoli, leading to insufficient oxygen supply to the body's organs and tissues. Therefore, exercising in fog often results in shortness of breath, chest tightness, and fatigue. It is best to choose a favorable weather environment for exercise. During foggy seasons, outdoor exercise can be scheduled for the afternoon. Pollution in cities is usually heavier before sunrise or in the evening, so exercise can be scheduled between 10 am and 3 pm. The air is freshest after rain, making this a good time for physical activity.

Why should you avoid exercising under elevated highways? As we all know, motor vehicles are "mobile sources of pollution" in cities, emitting large amounts of exhaust fumes containing carbon monoxide, hydrocarbons, nitrogen oxides, particulate matter, and formaldehyde. On elevated highways, due to the high speeds and heavy traffic, large amounts of nitrogen oxides are emitted. Furthermore, the buildings alongside elevated highways are generally tall, hindering the dispersion of exhaust gases. Therefore, the concentration of nitrogen oxides in the air near elevated highways is relatively high. If you exercise in such a place, these toxic gases will enter your bloodstream through your lungs, causing oxygen deficiency and affecting your respiratory, cardiovascular, and cerebrovascular systems. Additionally, nitrogen oxides and nitrogen hydrides combine and, under the influence of ultraviolet rays in sunlight, can form a highly irritating pale blue smog, whose main components include ozone and formaldehyde. This smog is highly irritating to the eyes and respiratory tract, and can cause symptoms such as tearing, sneezing, coughing, difficulty breathing, and asthma.

What are the taboos of swimming? (1) Avoid swimming before or after meals: Swimming on a full stomach will cause a large amount of blood to be supplied to the limbs, which will affect normal digestion. In severe cases, it may cause abdominal pain, vomiting, or even stomach cramps. Swimming on an empty stomach will affect appetite and digestive function, and may also cause dizziness, weakness, and other accidents during swimming. (2) Avoid swimming after strenuous exercise: Swimming after strenuous exercise will continue to increase the burden on the heart and lungs. At the same time, the sudden drop in body temperature will also easily cause a decrease in resistance, making one susceptible to colds and other diseases. (3) Avoid swimming under the sun for a long time: Prolonged exposure to the sun will cause sunspots, and in severe cases, it may lead to photodermatitis. When swimming outdoors, pay attention to sun protection measures and try to rest in places where the sun cannot directly shine. (4) Avoid swimming for too long: The duration of swimming should be 1.5 to 2 hours. Swimming for too long will cause a large amount of body heat to dissipate, and the skin will develop "goosebumps," which is very detrimental to the body and may even lead to dangerous situations such as exhaustion and cramps. (5) Avoid swimming after drinking alcohol: Swimming depletes the body's glucose reserves and lowers blood sugar. Alcohol metabolism inhibits the normal physiological function of the liver, hindering the conversion and normal storage of glucose in the body, thus causing accidents. (6) Avoid neglecting post-swim hygiene: After swimming, dry your body as soon as possible, apply chloramphenicol eye drops, and drain nasal secretions. Afterward, do some relaxation exercises or massage your limbs. If possible, sunbathe for 15-20 minutes to prevent muscle stiffness. (7) Swimming is contraindicated for the following conditions: high blood pressure, heart disease, epilepsy, otitis media, conjunctivitis, and certain skin diseases. Swimming may not only aggravate or worsen these conditions but may also infect others.

What are the precautions for middle-aged men to jog? (1) Warm up before running, such as taking a walk, swinging your arms, kicking your legs, etc. You can start running after 10 minutes of warm-up. (2) Strictly control the amount of exercise and do not run for too long each time. If you feel unwell, such as having difficulty breathing, chest tightness, chest pain, palpitations, dizziness, etc., gradually reduce your running speed until you can walk normally. Do not stop exercising immediately. (3) Some patients with certain diseases should not jog for fitness. For example, patients with cirrhosis, unstable tuberculosis, arthritis that affects normal function, severe diabetes, hyperthyroidism, severe anemia, bleeding tendency, cardiovascular disease, myocardial infarction, frequent angina pectoris, etc. (4) Running should be done gradually. Do not run too long a distance at once, otherwise you will easily become overly fatigued and put too much burden on your heart. (5) Breathe naturally, evenly, and smoothly while running, and coordinate with the rhythm of running. If you are out of breath, it means that you are not used to running too fast. You should slow down and adjust your breathing. (6) When running, it is advisable to take small steps and not to land on your heels first. It is generally better to land on your toes first and then gradually transition to your heels. Your knees should be elastic when your feet land and your steps should be rhythmic. (7) When running, it is more appropriate to swing your arms back and forth and slightly outward. Your upper body should lean slightly forward and try to relax all your muscles. (8) When you finish exercising, you should gradually slow down and do some stretching exercises, such as stretching your arms, kicking your legs, moving your head, and twisting your waist. These stretching exercises can help improve the flexibility of the body and reduce muscle fatigue. Do not sit down to rest all at once. (9) Avoid running immediately after meals, or in very cold, hot, humid, or windy weather. Do not eat immediately after running. It is advisable to rest for a while. (10) You will sweat a lot when running. Be careful not to remove your clothes easily to avoid catching a cold. (11) Do not take a shower after running, do not drink a lot of cold drinks immediately, and do not be exposed to cold wind. (12) Jogging should be done in quiet and clean places such as parks, and not on the side of the road.
