1 . Costa Rica’s jungles might seem an unlikely spot for a group of medics (医学工作者) to gather together. But struggling through this dense stretch of Central American wilderness, that’s exactly who you might encounter.

Trading medical instruments and lab-made medicines for rafts and snake venom, these medics come together under the guidance of World Extreme Medicine (WEM), an organisation training medical staff like nurses and doctors to work in the world’s most unstable and remote conditions.

Extreme medicine is a subdiscipline (分支) of medicine in which healthcare providers respond to crises in war zones, assist those left behind after humanity’s most horrific disasters, and conduct medicine not just on land, but also deep beneath the sea and even in outer space. While all medics need to think on their feet, Mark Hannaford, the founder of WEM, explains that for extreme medics, that need is heightened. Medics might treat a patient in the burning heat of a desert, on an ice-cold tundra(苔原), or stabilize a person at altitude or in the dark. Despite this, he says, “you don’t need to run a marathon with a backpack on every day to be an extreme medic. Physical fitness is not the challenge. The challenge is adequately preparing yourself for the environment you are going into.”

“You really have to take good self-care in these environments,” adds pre-hospital lead and extreme medicine trainer, Eoin Walker. In places like Costa Rica, he teaches medics skills in security, diet and wound closure etc.. But medics also learn to care for their own physical and mental health. “In the UK, we don’t have to remember to drink every hour, or clean and dry our feet, or look at our calorie content — but you do in that environment,” he says.

“People who live where disaster hits still have issues like diabetes, babies are still being born, people need medical treatment,” says Mark. And with more disasters set to strike, their needs will only increase. “Training extreme medics is becoming more important as we face environmental challenges like climate change,” he adds.
