我们吃辣的食物时为什么会流汗?
why do we sweat when we eat spicy food?我们吃辣的食物时为什么会流汗?Ariel Williams这是个有意思的问题,其答案也很有趣。我很喜欢吃辣,因此感到十分好奇,便去了解了一下相关知识。辣椒和辣椒酱之所以让人产生火辣感,大多是因为他们所含有的辣椒素。辣椒素有选择性地与TRPV1蛋白质结合,TRPV1蛋白质位于感知痛觉和热觉的神经细胞的细胞膜上。TRPV1是具有热活化性的钙离子通道,当温度在37-45℃时(98.6-113℉)通道会打开。而当辣椒素与TRPV1结合时,钙离子通道会在低于37℃(正常人体体温)的温度下打开,这就是为什么辣椒素与热觉相关。此时你的身体错以为自己暴露在高温中,而你所暴露的组织的耐热力变得很低,所以这时身体有种被灼烧的错觉。你的身体用它通常为你降温的方法来应对这样的热。辣椒素扩散,脸红肿胀显现,血液带走了热,带来了灼伤的愈合因子。一些痛感导致出汗,这时你的身体与痛感产生化学反应,设法与其中和。奇辣无比的辣椒甚至会损伤皮肤,例如把夏宾奴辣椒切成丁放在皮肤上,辣椒素扩散时,皮肤变红,有些肿胀。总的来说这个反应也没什么损害,只不过疼痛有可能给心脏和血压带来压力。这一反应也在医学上使用。长期接触辣椒素导致神经末梢上传递痛觉的化学物质被耗尽。这一现象通常和麻醉术相辅相成,因为辣椒素的应用,疼痛和刺激就暂时感觉不到了。现在有与“抗TRPV1药物的发现和研发”相关的研究,据悉一些有潜力的药物会在2013-14年用于活性试验。小贴士1.现在点击下面这行小三角,可以直接查看英文版了2.拖到文末可以参与评论3.如果有什么有趣、有用的Quora题目,可以发给我们。点击这里直接查看「英文版」Ariel WilliamsThis is both a fascinating question and has an equally fascinating answer. I love hot food so I looked into this a while back and was really intrigued.Capsaicin is responsible for the burn in most hot peppers and hot sauces.
selectively binds to a protein known as TRPV1 that resides on the membranes of pain and heat-sensing neurons. TRPV1 is a heat-activated calcium channel that opens between 37 and 45 °C (98.6 and 113 °F, respectively). When capsaicin binds to TRPV1, it causes the channel to open below 37 °C (normal human body temperature), which is why capsaicin is linked to the sensation of heat.So what happens is your body thinks it is being exposed to heat. Your tolerance for heat in the exposed tissues goes so low that the temperature of your own body is mistaken for a serious burn. Your body responds to this heat like it would normally by trying to cool you. Capillaries expand and redness and swelling begin so the blood can carry heat away and bring in healing factors for injury. Some of the pain may also cause stress sweating as your body is chemically reacting to pain and trying to counteract it.A potent enough concentration of hot peppers can even aggravate the skin. An example of this would be the effect of diced habenero chili sitting on your skin. The skin turns red and swells a little as the capillaries expand. No damage is actually caused as a whole by this reaction other than maybe the stress to your heart and blood pressure from the pain.This effect is also used medically. It turns out that chronic exposure to causes the chemicals that communicate pain to be depleted from your nerve endings. This type of application is normally combined with the numbing effects of an anesthetic so the pain and irritation is temporarily not felt from the application of . There is currently study into the and several potential medicines are believed to be in active trials as of 2013-14.近期热门

你好,是最近出现的吗。出汗异常大多数和人的交感神经有关系的,如果仅仅是头部出汗,建议您检查一下颈椎。可能是颈交感干受刺激造成的
恩,是的,请问这个跟肾虚有关吗?最近老是两条腿站一会就疼。
你好,肾虚的诊断很模糊,没有一个标准来界定。你的下肢疼和头部出汗可能关系不大,另找原因。
下肢困疼,找不到原因,不缺钾不缺钙,有一个多月了!
双下肢吗,在什么情况下出现的疼痛,休息可不可以缓解

流汗多一般与个体差异有关系的,与植物神经失调也有关系的.其中少数人可有家族史,在情绪波动或进食辛辣食物时加重.中医认为易出汗是营卫不和引起的体虚自汗,如没有其他...
盗汗、虚汗多是由于体质虚弱所致,往往由于身体无太大的不适而被许多家长忽视。其实儿童盗汗、虚汗是不容忽视的,因为常出虚汗极易导致脱水、体内电解质平衡紊乱、微量元素...
