这些病竟然对人体有好处?Are these diseases actually beneficial to the human body?

咳嗽。是呼吸系统中最常见的症状之一,是人体的一种保护性措施,对机体是有益的。当呼吸道黏膜受到异物、炎 症、分泌物或过敏性因素等刺激时,即反射性地引起咳嗽,有助于消除自外界侵入呼吸道的异物或分泌物、消除呼吸道刺激因子。如果一咳嗽就用止咳药物,则会把 加重炎症的脏东西都滞留在呼吸道里不利于炎症的消除。

出现咳嗽时,应在保暖的同时补充大量水分,同时避免胡椒、洋葱等辛辣食物刺激呼吸道。如频繁咳嗽还伴有发烧、胸痛、体重减轻等症状时,应立即就医。

呕吐。也是为了排出对人体有害的物质,以减少吸收,是机体的一种防御反射。若此时采用药物止吐,会使有害物 质滞留在体内,危害健康。如果是单纯呕吐,应适量补充水分,避免水和电解质紊乱。如果还伴随有肠胃不适,就应在补水的同时按摩胃部和腹部。呕吐后别急着进 食,可以稍加活动,让身体舒展后再进食。若呕吐反复发作或伴有腹痛、发烧等症状时,应立即就医。

腹泻。尤 其是排泄物有异臭时,往往是身体正在排出来自食物或其他方面的毒素。当腹泻来临时,千万不要走进“治疗”误区,如:有腹泻就用止泻药;认为腹泻就是炎症, 该吃消炎药;吃去痛片缓解腹泻疼痛;严重时吃药,停止时就停药;腹泻时多喝水,补充丢失水分;腹泻时少吃,腹泻后多吃等。遇到腹泻时,应采取因势利导法, 例如喝一杯热水,帮助肠道尽快排完毒素。如果有严重的腹泻,便意频频、排便量少、肛门部有痉挛性疼痛,或排泄物带血,或同时伴有腹痛、发烧、呕吐等症状 时,应该立即就医。

流鼻血。我们可以把流鼻血看作是机体自我“去火”的一种方式。当人们饮水减少、辛辣食物吃得过多,以及环境干燥、体内“上火”时,机体就常常自行选择薄弱的鼻黏膜“去火”。所以流鼻血时大可不必担心,它会在短时间内自行终止。

但是,如果经过一段时间鼻血依然不止就应当及早检查。这是,你可以前倾身体、顺其自流,用纸巾轻轻吸去流出的鼻血。量较大时,可捏紧鼻翼柔软处 几分钟,或举起流血鼻孔的对侧手臂帮助止血。如果鼻子大量流血不止时应立即就医,这往往是体内血管硬化、血压过高等疾病引起的。

发烧。体温一旦超过了摄氏37度就属于发烧。医学研究证实,免疫细胞的作战能力会随体温的升高而增高,同时 高体温也使血液中的铁离子浓度减少,造成病原体生长所需要微量铁离子供给不足,进而抑制病原体发育,这些才是抗病的主力,药物只是外援。所以,如果在发烧 一开始就服退烧药,反而可能加重病情。体温不超过摄氏38度,且精神、食欲没有受到影响时,可以将冰块置于额头缓解不适,同时多喝水,适量补充维生素和矿 物质,可以吃一些富含营养且清淡的食物。若体温高于摄氏38.5度,或持续低烧不退,或伴有发疹、剧烈头痛、关节痛、痉挛症状时,应立即就医。


Cough. It is one of the most common symptoms in the respiratory system and a protective measure for the human body, which is beneficial to the body. When the respiratory mucosa is stimulated by foreign objects, inflammation, secretions, or allergic factors, it reflexively causes coughing, which helps to eliminate foreign objects or secretions that invade the respiratory tract from the outside and eliminate respiratory irritants. If cough suppressants are used immediately after coughing, it will trap the dirt that exacerbates inflammation in the respiratory tract, which is not conducive to the elimination of inflammation.

When coughing occurs, it is necessary to keep warm and replenish a large amount of water, while avoiding spicy foods such as pepper and onions that can irritate the respiratory tract. If frequent coughing is accompanied by symptoms such as fever, chest pain, and weight loss, medical attention should be sought immediately.

vomit. It is also a defense reflex of the body to eliminate harmful substances and reduce absorption. If medication is used to stop vomiting at this time, harmful substances will remain in the body, posing a health hazard. If it is simply vomiting, it is necessary to replenish water appropriately to avoid water and electrolyte imbalance. If there is also gastrointestinal discomfort, massage the stomach and abdomen while replenishing water. Don't rush to eat after vomiting, you can move your body a little and let it stretch before eating. If vomiting recurs or accompanied by symptoms such as abdominal pain and fever, seek medical attention immediately.

Diarrhea. Especially when there is a foul odor in excrement, it is often due to the body being excreting toxins from food or other sources. When diarrhea strikes, do not fall into the "treatment" misconception, such as using antidiarrheal drugs if you have diarrhea; Believing that diarrhea is inflammation and should be treated with anti-inflammatory drugs; Take painkillers to relieve diarrhea pain; Take medication when severe and stop when necessary; Drink plenty of water during diarrhea to replenish lost fluids; Eat less during diarrhea and eat more after diarrhea. When encountering diarrhea, one should adopt a strategy of adapting to the situation, such as drinking a cup of hot water, to help the intestines quickly eliminate toxins. If there is severe diarrhea, frequent bowel movements, low defecation volume, spasmodic pain in the anus, or bloody excrement, or accompanied by symptoms such as abdominal pain, fever, vomiting, etc., medical attention should be sought immediately.

nose bleeding. We can view nosebleeds as a way for the body to self regulate and reduce internal heat. When people drink less water, eat too much spicy food, and when the environment is dry and the body is overheated, the body often chooses to "reduce" the weak nasal mucosa on its own. So there's no need to worry about nosebleeds, they will stop on their own in a short period of time.

However, if nosebleeds persist after a period of time, early examination should be conducted. This is, you can lean forward, let it flow naturally, and gently use a tissue to suck off the nosebleed that flows out. When the amount is large, you can pinch the soft part of the nose for a few minutes, or lift the opposite arm of the bleeding nostril to help stop the bleeding. If there is excessive bleeding from the nose, immediate medical attention should be sought, as this is often caused by diseases such as arteriosclerosis and high blood pressure in the body.

fever Once the body temperature exceeds 37 degrees Celsius, it is considered a fever. Medical research has confirmed that the combat ability of immune cells increases with body temperature, and high body temperature also reduces the concentration of iron ions in the blood, resulting in insufficient supply of trace iron ions required for pathogen growth, thereby inhibiting pathogen development. These are the main forces of disease resistance, and drugs are only external assistance. So, taking antipyretic medication at the beginning of a fever may actually worsen the condition. When the body temperature does not exceed 38 degrees Celsius and the mind and appetite are not affected, ice cubes can be placed on the forehead to relieve discomfort. At the same time, drink plenty of water, supplement vitamins and minerals in moderation, and eat some nutritious and light foods. If the body temperature is above 38.5 degrees Celsius, or if the low-grade fever persists, or if accompanied by rash, severe headache, joint pain, and spasms, medical attention should be sought immediately.
