Prevention of "heatiness" during travel and safety during self-driving tours: Human stress regulation and driving ergonomics
Many people experience symptoms such as rapid heartbeat, facial flushing, general heat, restlessness, decreased appetite, dark urine, and constipation while traveling. Some even develop rashes on their lips, corners of the mouth, or even face. These symptoms are commonly referred to as "internal heat" or "heatiness." "Internal heat" is caused by an imbalance in the body's organs, medically termed an irritative illness. During travel, frequent changes in location and living environment, coupled with arduous journeys, require significant energy and physical exertion, leaving the body's systems constantly under stress and in a state of "stress." Once the body enters a stress state, it disrupts the coordination, balance, and stability of its internal environment, leading to illness. To avoid "internal heat," the following points should be noted: 1. Prepare thoroughly: Before departure, carefully plan your travel route, travel times, and belongings. This will allow you to remain calm and composed regardless of any unforeseen circumstances. 2. Maintain a regular lifestyle: Adhere to a pre-prepared schedule for your trip and avoid disrupting your itinerary. 3. Get up and go to bed on time, and eat meals regularly and in appropriate portions. 4. Eat more cooling foods: Fresh leafy green vegetables, fruits, and green tea all have beneficial effects. 5. Pay attention to the balance between work and rest: Arrange various activities appropriately and in moderation, and ensure sufficient sleep to avoid excessive fatigue and decreased immunity.
Driving trips are the most desirable, and it is important to plan the itinerary carefully before setting off. 1. Adjustments to relevant parts: (1) Carefully adjust the seat. When adjusting the seat forward and backward, pay attention to the relationship between your legs and the accelerator, clutch, and brake pedals. When you press the brake pedal down to the deepest point, your legs should still be slightly bent. When adjusting the seat up and down, your head should be at least a fist's distance from the roof of the car. (2) Adjust the steering wheel up and down. When you are sitting with your back against the seat, your wrist should fall on the steering wheel when your arm is straight. This is the best distance for the steering wheel. (3) Adjust the rearview mirror. You should be able to see 2/3 of the ground and 1/3 of the sky. This is the best position for adjusting the mirror up and down. 2. Adjust the lumbar support: The purpose is to make the seat support your waist. When you lean back, your waist should not be suspended in the air. This will reduce fatigue during driving. 3. Adjust the headrest: The best position for the headrest is when the center line of the pillow is exactly in line with your eyebrows. When driving, the driver should be able to rest his head on the headrest. This is both comfortable and safe.
Men should pay special attention to nourishing their kidneys because the kidneys are the most creative organ. The *Huangdi Neijing* (Yellow Emperor's Inner Classic) says that the kidneys can "produce skills," meaning they can generate talent. If a person is dexterous, this is actually a sign of sufficient kidney essence. Many men focus on nourishing their kidneys because vital energy (yuanqi) is stored in the kidneys. As the saying goes, "A person lives on a breath," and this breath is vital energy. What is this vital energy? Simply put, it's the true energy we are born with. It's a bit like going to a gas station to get a gas cylinder. You don't know beforehand which cylinder to take, or which one has enough gas, but as long as you get one, it's suitable for you. If you only get a half-full cylinder, it means your vital energy is very weak. If you want to live a long life, you must try to avoid using fire, or keep the valve very low-this is called nourishing. If your gas cylinder has plenty of gas, and you don't use it sparingly but instead turn the flame up high, it won't last long. In fact, the valves and energy mechanisms in life shouldn't be opened too wide. So what kind of Qi (vital energy) does the human body possess? The Qi in the human body is Lesser Yang, a gentle fire, a warm and moist state. In the words of the *I Ching*, it's called *yinyun*, a very moist and nourishing substance, the fire of Lesser Yang, a gentle fire. So where is primordial Qi stored? Primordial Qi is stored in the kidneys. If we consider our five internal organs as five brothers, then primordial Qi is like the parents. Parents generally live in the eldest brother's house, so the kidneys, among the five internal organs, are equivalent to the eldest brother.
