It is said that the running addicts who love marathons or run every day are not doing something unbearable, but on the contrary, they are experiencing a runner's high. That's why they love this game so much and keep running every day no matter what.

So what is a runner's high? Previous research attributed it to endorphins, which produce a short-lasting euphoric state after an intense workout. However, the latest study shows that endorphins cannot cross the blood-brain barrier. Instead of endorphins, it is endocannabinoids that can move easily across the cellular barrier separating the bloodstream from the brain and making runners feel calm and relaxed. ①

From my personal experience, I have occasionally experienced some highs while running. They all occurred while running indoors on a treadmill. I never feel very comfortable when running in the open air. Wind, sun, cold, heat, humidity, pollen, and various road conditions, especially rocky, hard road, etc., can cause various types of discomfort. However, a treadmill in a gym provides a relatively steady and well-controlled environment where a runner's high can easily occur, at least for me.

Sometimes it happens when I run extremely fast (speed level 12). It's a kind of extreme euphoric state that only lasts for a very short time because sprinting is too exhausting to sustain for long. Other times, when I run slowly like Speed Level 6, when I try to exert all parts of my body and activate them, suddenly comes the high moment, a long-lasting state of extreme comfort, slow but satisfying. Every part of my body is energized and activated. I, henceforward, fall in love with running again.

Running, especially jogging, lifts your mood, improves your state of mind, and reduces free radicals, waste, and toxins that have accumulated in your body. Run whenever and wherever. You will love it.

跑者高潮

有人说，那些喜欢马拉松或每天跑步的人并不是在做一件痛苦的事情；相反，他们是在享受跑步者的高潮。这就是为什么他们如此热爱这个运动，并无论如何都坚持每天跑步。
那么，什么是跑步者的兴奋？以前的研究将其归因于内啡肽，它使人们在剧烈运动后经历短暂的欣快感状态。然而，最新的研究显示，内啡肽不可能通过血脑屏障；代替内啡肽的是内大麻素，它可以轻易地穿过分隔血液和大脑的细胞屏障，使跑步者感到平静和放松。①
据我个人的经验，我在跑步时偶尔会有一些高潮。所有这些都发生在室内跑步机上的跑步过程中。我从来没有在户外跑步时感到极度愉悦。风、阳光、寒冷、炎热、潮湿、花粉、各种路况，特别是岩石硬路等，都可能引起各种不适。然而，健身房内的跑步机提供了一个相对稳定和良好的受到控制的环境，跑步高潮很容易发生，至少对我来说是这样。
有时它可能会在我跑得极快时发生（12级速度档）。这是一种极端的兴奋状态，持续时间很短，因为冲刺太累了，无法维持很长时间。其他时候，当我在慢跑时，如6级挡位，如果我努力使身体的每个部分都得到锻炼，使它们被激活，那么突然间就会出现兴奋的时刻，这是一种持久的极端舒适的状态，缓慢但令人满意。身体的每一个部分都被激发和激活了。我，从此再一次爱上了跑步。
跑步，尤其是慢跑，能创造高涨的情绪，改善精神状态，减少自由基、废物和体内积累的毒素。无论何时何地，都跑起来吧。你会爱上它的。
