California<\/a> has just set off all the alarms, as authorities have warned that our health is at risk due to poor air quality. They have detected very dangerous levels of pollution. The culprit has a name (PM2.5<\/a>), and they have warned the population to stay at home<\/a>, avoid outdoor activities<\/a>, and take extra precautions if you belong to vulnerable groups<\/a>. Pure prevention, we tell you what is happening.<\/p>\n

What is PM2.5?<\/p>\n

These are microscopic particles that float in the air. They measure less than 2.5 micrometers<\/a> (30 times thinner than a human hair). You cannot see them and you cannot smell them, but they stick to the walls of the lungs and from there they pass into the bloodstream.<\/p>\n

These particles come from wildfire smoke<\/a>, cars<\/a>, or fuel burning in industrial processes, and they form a deadly cocktail for our lungs<\/a>.<\/p>\n

And why are they more dangerous than others?<\/p>\n

Our body usually defends itself well against pollutants, but these particles are so small that they reach the pulmonary alveoli<\/a> (if you are asthmatic, you know well what we are talking about when the alveoli close).<\/p>\n

These particles stick to the lungs, worsen asthma<\/a>, generate cardiovascular problems and even irritate our eyes (and yes, also in completely healthy people with no previous conditions).<\/p>\n

And you do not need to spend the whole day outside, just a couple of hours outdoors is enough for them to enter your body.<\/p>\n

What is happening?<\/p>\n

The United States Environmental Protection Agency (EPA)<\/a> has detected that PM2.5 levels have risen to categories considered \u201cunhealthy\u201d for the general population (sensitive groups, of course, are the first to be warned).<\/p>\n

This has formed due to wildfire smoke and the lack of air movement during recent weeks. Pollution has accumulated over a matter of days until reaching these levels.<\/p>\n

Who is most affected by this type of air?<\/p>\n

Children
\nOlder adults
\nPregnant women
\nPeople with asthma, lung diseases or heart problems<\/p>\n

And what symptoms does it cause?<\/p>\n

Difficulty breathing
\nPersistent cough
\nDizziness
\nChest pain<\/p>\n

What do authorities recommend?<\/p>\n

Authorities have indicated that people should limit going outside as much as possible, and if they do go out, to wear masks<\/a> (just like during the pandemic), keep doors and windows closed, and avoid using cars.<\/p>\n

It is best that if you have to go out, you use a mask with a filter (although it will not eliminate the risk 100 percent, be careful with that), and if you have air purifiers<\/a> at home, use them.<\/p>\n

Pollution is becoming more frequent<\/p>\n

California has already experienced several alerts for unhealthy air, especially during wildfire season. All of this is intensified by climate change<\/a>, of course, which causes many more fires.<\/p>\n

Experts explain that this type of exposure to particles, in the long term, can generate chronic diseases and increase the risk of premature death<\/a>, so we are facing a real public health problem.<\/p>\n

Guidelines for the coming days<\/p>\n

Everything will depend on the weather and how it evolves. If wind picks up and can carry the particles away, PM2.5 levels could drop, but it is possible that alerts will remain for several days.<\/p>\n

The most important thing now is that you stay informed and follow the official instructions from authorities. If you have to go out, do so with caution and as soon as you get home, take off your clothes and take a thorough shower. Prepare your kit with supplies and plenty of junk food so you can survive this \u201clockdown\u201d. We have to prioritize our health.<\/p>\n","protected":false},"excerpt":{"rendered":"California has just set off all the alarms, as authorities have warned that our health is at risk…\n","protected":false},"author":2,"featured_media":432570,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[47],"tags":[192,79],"class_list":["post-432569","post","type-post","status-publish","format-standard","has-post-thumbnail","category-environment","tag-environment","tag-science"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/posts\/432569","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/comments?post=432569"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/posts\/432569\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/media\/432570"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/media?parent=432569"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/categories?post=432569"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/tags?post=432569"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
