上个周末给割草机换皮带，随手清理积附在机器上的干草，无意被坚硬的草根扎到指甲底下，那种刺痛立即传遍全身，......。痛定思痛，除了后悔没有带手套外，我居然还想到小说《红岩》里那个国民党特务给“江姐”的十个手指头钉上竹签、而当事人却无动于衷的情节。我现在一个手指头被一根干草扎入之痛尚且如此，一根一根竹签植入，那种折磨如何承受。这么一想，我倒是觉得“神医”华佗是懂心理学的了。因为动物的肌理、生理反应是相同的，他“恐君侯惧耳”，所以在给关云长“刮骨疗毒”前要求将关的头脸蒙上，被关拒绝。“吾视死如归，有何惧哉？”详情见“刮骨疗毒”。我有理由相信，同红岩里钉竹签一样，《三国演义》里关云长“刮骨疗毒”情节也是假的。
看别人花粉过敏以为那不算病，一直要临到自己头上时才知道那种难受简直是要人命。很多年前一到春天就听朋友抱怨，还说眼睛痒得恨不能把眼珠给挖掉。那时因为从来没有过敏反应，所以我无法“感同身受”要把眼珠挖出的那种怨恨。这就像富人不知道这个世界上穷人为什么穷，穷人的日子是怎么过的，所以有“何不食肉糜”的典故。
大概在十多年前，有一天在割草时打了一个巨响的喷嚏，让我印象深刻。似乎从那时开始过敏症状显现，后来越来越严重。流鼻涕大喷嚏都还能忍受，可是眼睛痒却非常难熬，点止痒药水也只能管一会，所以经常要用手去揉，眼球红肿充血不说，还造成有“沙眼”的症状，眼皮一动就痛。可是眨眼皮是下意识的行为，不受大脑控制。有一天还引起（偏）头痛，吃了偏头痛的药也不管用，真是苦不堪言。住医院后能够结识病友，因为同样的病后，人会同病相怜。前几天我给久未联系的老友打电话，谈及过敏，好像一旦沾上就好不了了。我说我已经吸取往年的教训，三月底开始老老实实每天吃一粒抗过敏的药，在整个“人间四月天”里，只要在室外我都带N-95口罩，虽然症状有所减轻，不过仍然喷嚏、鼻涕不断，眼睛红肿奇痒。这种情况下，哪里还有心情享受四月天呢，就希望春天尽快过去，夏天早点来吧，否则这过敏的折磨不知道还要持续多久呢。
New Study Says Climate Change Is Indeed Making Your Allergies Worse
If you've been sneezing and rubbing your eyes more and more each year, you're not alone. Pollen season is getting longer and more intense thanks to Climate Change.
Scientists have made this connection before, but a recent study published in Proceedings of the National Academy of Sciences that analyzed long-term pollen data found that pollen concentrations have increased by over 21% in North America, and the season is over 20 days longer than it was in 1990.
The paper analyzed changing pollen counts across 60 North American stations from 1990 to 2018. The researchers also looked at several climate models to see what role climate change played in these increases. They found that human-caused climate change was the main driver of longer, more intense pollen seasons over the last three decades.
How climate change impacts allergies
Aside from warmer temperatures, higher concentrations of CO2 and forms of air pollution are contributing to more intense allergy seasons. When air pollution particulates attach to pollen grains, it can make them explode into tiny pieces that easily get into your respiratory tract. CO2 can also make plants bloom more, which results in even more pollen.
The uptick in pollen counts could have major, long-lasting impacts on respiratory health, especially for people with preexisting respiratory illnesses like asthma. But even people who've never had allergies before might start experiencing them, and become more susceptible to viral infections which enter the body through the respiratory tract.

Increased pollen counts aren't the only things that might have you reaching for the tissues. Scientists have also found that pollen has become more potent, so less pollen could trigger a reaction comparable to a higher concentration of pollen several years ago.
While pollen season extends into the fall, the study found the biggest increases in pollen concentrations happen in the spring. This makes sense considering how many pollen-producing plants begin to bloom in the spring. Researches also noted the largest, most consistent pollen increases were in Texas and the midwestern United States.
What you can do to keep your allergies in check
Aside from using over-the-counter antihistamines and other allergy medications to treat symptoms, you can try and avoid exposure to pollen as much as possible. Check your local pollen alerts, and on high pollen count days, keep your windows closed and stay inside from 10 a.m. to 2 p.m..
If you have to go out for a while, leave your shoes outside when you come back, and take your clothes off to wash as soon as you come inside. It's also a good idea to shower at night since pollen can get trapped in your hair.
Vacuuming regularly and buying a couple HEPA air filters will also help keep allergies at bay while your inside your home.
