Four Essentials For Human Body Survival 人体生存的四个必需品

 At the end of the day, there are only 4 things a body needs to survive: water, food, oxygen, and functioning nervous system.

人体生存的四个必需品

 归根结底，人体生存只需要四样东西：水、食物、氧气和正常运转的神经系统。

1. Water

Water is more than just a thirst-quencher. Almost every system in the body is dependent on water in some shape or form. The human body is approximately 60% water. Water regulates body temperature and helps the liver and kidneys flush out toxins. Water lubricates joints and moisturizes the eyes, nose, and mouth. Even oxygen and nutrients are carried to cells by water. Without water the body cannot function. Breathing, sweating, and even going to the bathroom are all ways a person loses water. To maintain a healthy body, people need to replenish water levels and continue drinking water throughout the day. Direct water consumption is best. Beverages such as electrolyte drinks and fruit such as watermelon can help refill the body’s water supply. Standard recommendation is that women drink a minimum of 11.5 cups of water daily and men 15.5 cups. Use water-cure formula: ( your body weight in kg ) × 32.53 = ( total amount of plain water in milliliters, per day , your body need )

1. 水

水不仅仅是解渴的饮料。几乎身体的每个系统都以某种形式依赖于水。人体大约60%是由水组成的。水调节体温，帮助肝脏和肾脏排出毒素。水润滑关节，滋润眼睛、鼻子和嘴巴。甚至氧气和营养物质也需要水来输送到细胞。没有水，身体就无法正常运作。呼吸、出汗，甚至上厕所都会让人流失水分。为了保持健康的身体，人们需要补充水分，并全天持续喝水。直接喝水是最好的。电解质饮料和西瓜等水果可以帮助补充身体的水分。标准建议是女性每天至少喝11.5杯水，男性至少喝15.5杯水。 使用水疗法公式：（您的体重，以公斤为单位）× 32.53 =（您的身体每天所需的白开水总量，以毫升为单位）

2. Food

Food provides essential nutrients to the body. These nutrients are in turn used for energy, cell growth, and repair. Food keeps the immune system happy and, as a result, poor diets often lead to numerous health problems. Food can be broken down into four essential groups: fats, carbohydrates, protein, and vitamins. Fats provide energy and help absorb vitamins. Fats can control cholesterol levels and are essential for growth and development. Carbohydrates are converted to fuel. Fiber is a type of carb that assists in digestion, regulates blood sugar levels, and keeps hunger levels in check. Protein helps the body repair damaged organs, tissues, and bones. Protein is found in every cell in the human body. The digestive tract breaks down proteins into amino acids. There are 20 amino acids the body needs to function properly. And while the body can produce 12, there are still 8 that must be consumed through food. Vitamins play a role in every bodily function. The human body needs 13 types of vitamins to function properly.

2. 食物

食物为人体提供必需的营养素。这些营养素反过来又被用于能量、细胞生长和修复。食物维持免疫系统的正常运作，因此，不良的饮食习惯往往会导致许多健康问题。食物可以分为四大类必需营养素：脂肪、碳水化合物、蛋白质和维生素。脂肪提供能量并帮助吸收维生素。脂肪可以控制胆固醇水平，对生长发育至关重要。碳水化合物被转化为能量。纤维是一种碳水化合物，有助于消化、调节血糖水平并控制饥饿感。蛋白质帮助身体修复受损的器官、组织和骨骼。蛋白质存在于人体的每个细胞中。消化道将蛋白质分解成氨基酸。人体正常运作需要20种氨基酸。虽然人体可以自行产生12种氨基酸，但仍有8种必须通过食物摄入。维生素在人体的每项功能中都发挥着作用。 人体需要 13 种维生素才能正常运作。

3. Oxygen

Oxygen is breath. Everything else spared, without oxygen, life is not possible. Oxygen is inhaled into the lungs and then dispersed throughout the body by red blood cells. Oxygen gives energy to cells by burning through the sugar and fatty acids that are consumed. The same red blood cells that carry oxygen through the body also carry carbon dioxide out of the body. Exhaling also removes carbon dioxide from the body. Take Note: Anyone, regardless of age, when does not drink enough water, overtime, will cause water deficits in the body, in turn, causes the human lungs 🫁 alveoli* shrink and cellular dehydrated.   *Alveoli are tiny air sacs in the lungs that exchange oxygen and carbon dioxide with the blood. The lungs wall must be moist for gaseous exchange to be possible. Asthma is the result of lungs dehydration. ( Learn more here )

3. 氧气

氧气就是呼吸。如果没有氧气，生命就无法维持。氧气被吸入肺部，然后通过红细胞输送到全身。氧气通过燃烧消耗的糖和脂肪酸为细胞提供能量。红细胞不仅携带氧气到全身，还将二氧化碳排出体外。呼气也会将二氧化碳排出体外。注意：任何人，无论年龄大小，如果长期不喝足够的水，都会导致体内水分不足，进而导致人体肺部🫁肺泡*萎缩，细胞脱水。*肺泡是肺部微小的气囊，负责与血液交换氧气和二氧化碳。肺壁必须保持湿润才能进行气体交换。哮喘是肺部脱水的结果。

4. The nervous system

The nervous system is the body’s command center. The nervous system collects data, processes the data, and responds accordingly. The system controls movement by transmitting nerve impulses between the brain and the rest of the body. The messages travel through neurons, synapses, and neurotransmitters. These messages tell the heart to beat, lungs to breathe, and limbs to move. The nervous system even tells the brain how to think. The nervous system has two parts: the central and peripheral. The central nervous system is made up of the brain and spinal cord. The peripheral nervous system makes up the rest of the body. When you eat anything, your body will produce dopamine, and this dopamine will calm down the nervous system.

4. 神经系统

神经系统是人体的指挥中心。它收集数据、处理数据并做出相应的反应。神经系统通过在大脑和身体其他部位之间传递神经冲动来控制运动。这些信息通过神经元、突触和神经递质传递。这些信息控制心脏跳动、肺部呼吸和四肢运动。神经系统甚至控制大脑如何思考。神经系统分为两部分：中枢神经系统和周围神经系统。中枢神经系统由大脑和脊髓组成。周围神经系统构成身体的其他部分。当你吃任何东西时，你的身体都会产生多巴胺，而这种多巴胺会舒缓神经系统。
