Himalayan High: dangers of the trek

Over the past few weeks I’ve shared all kinds of thoughts on an Everest Base Camp trek, one of the best long distance hikes anywhere in the world. I’ve also shared my thoughts on the best ways to prepare for the trek and which gear items you should bring along with you to the Himalaya. In this, the final article in the Himalayan High series, I’ll share some thoughts on the potential dangers of the trek.

Beyond a shadow of a doubt, the biggest danger that anyone trekking in the Himalaya will face is the altitude. It is the great equalizer when it comes to determining success or failure on a high mountain trek, and even the most physically gifted and prepared hikers can be laid low by the thin air. Common symptoms that are brought on by altitude include headaches, dizzy spells, nausea, shortness of breath, and a loss of appetite. More serious signs of AMS, or Acute Mountain Sickness, include lethargy, sometimes to an extreme level, an inability to sleep, and vomiting.

Most of the members of my trekking group experienced at least one of those symptoms to some degree or another. Nearly everyone reported headaches and nausea of varying degrees, with a few experiencing serious issues. Of our 12 person group, two were unable to complete the trek to Base Camp. One of those suffered considerable nausea and was lacking in strength, so he elected to go down of his own accord. The other, had a full on case of AMS, and was lethargic to the point of not being able to stay awake. She was slurring her words considerably and was physically ill to the point where she couldn’t keep any food down. It became so serious that she had to be carried down the mountain by our porters, and would eventually recover at a lower altitude.
As for myself, for the most part I suffered few problems from the altitude. I would often start the day with a slight headache and feeling a bit hung over, but once we hit the trail, I would soon shake off the sluggishness altogether. Unfortunately, I did suffer one side effect that has troubled me in the past – the inability to sleep well at altitude. I’d go to bed each night exhausted from the long day on the trail, and almost without fail, I’d wake up in an hour or two later, and be wide awake for most of the rest of the night. It was rather frustrating, especially over a 12 day hike.

Unfortunately, there isn’t a whole lot you can do about altitude. It is nearly impossible to prepare for unless you already live in the mountains, and as I said, it effects everyone differently. The best advice I can give is to make sure you’re proceeding up the trail at a slow, measured pace, and take the acclimatization process very seriously. Also, ask your doctor for a prescription of Diamox before you go. It is a drug that is very popular with mountaineers and helps ward off many of the effects of altitude sickness.

One ailment that was difficult to avoid is the dreaded Khumbu Cough. It is a dry, sometimes painful, hack that practically everyone hiking in the region contracts. The cough is a result of the extremely dry air and cold temperatures, causing an irritation of the bronchi in the lungs and seems to be exasperated by high levels of exertion. Everyone in my group, without exception, suffered the Khumbu Cough to some degree, including myself. But in an odd twist, my cough wasn’t so bad while I was actually in Nepal, but managed to somehow get worse after I came home. Avoiding the cough is not easy, but wearing a mask or covering your mouth and nose with a Buff, can help limit the damage.

The next most common problem that most travelers in the region experience is gastrointestinal issues, most often brought on by the food or water. Trekkers will generally eat each evening in the teahouses that they are staying at, and while the food doesn’t taste half bad, it has the potential to be problematic for exhausted hikers who are already dealing with all kinds of other conditions. The fact that all food items, and pretty much everything else for that matter, has to be carried up the mountain by porters, gives it ample opportunity to spoil, especially items that easily perishable such as meats and cheeses.

Like many places in the world, the water can be a challenge to deal with as well. You can fill your water bottles for free in most teahouses, but you’ll want to treat it with water purification tablets or use a filter of some kind before drinking it. If you don’t, you’re likely to suffer terrible GI issues, which isn’t a fun thing to experience when you’re out on a trail for hours at a time.

Fortunately, I was once again spared any GI issues, but other members of the group were not so lucky. Some suffered from travelers diarrhea, and were frequently looking for a private rock to serve as shelter while they heeded the frequent calls of nature. Others had outright food poisoning, getting sick from the food in general. My advice is to stick to basic foods and avoid anything exotic. You’ll also want to avoid meats and cheeses when ever possible, especially as you go higher.

As on any hike, you do run the risk of physical injury while trekking the Khumbu. There are plenty of places on the trail where you can slip and fall, damaging more than just your pride. Twisted ankles and knees are a real possibility, especially considering that some portions of the trail are make-shift stairs carved out of rock. After climbing up those stairs for a couple of hours, your tired legs are more likely to cause a stumble, and while there were a few such incidences in my group, no one was seriously injured.

One other common concern for travelers heading to Nepal is a potential chance encounter with the Maoist Rebels that are known to inhabit the countryside and remain active there, despite the fact that they won control of the government a few years back in democratic elections. In the past, those rebels were known to shake down trekkers for money and occasionally kidnap them as well. But those days are behind us, and visitors can now roam the countryside with out too much fear. They were seldom an issue on the road to Everest to begin with, and on my trek there was little sign of them outside of a few propaganda posters.

Like any trip to remote region of the world, there are always inherent dangers. But the amazing scenery, friendly people, and wonderful culture make this journey one that is well worth taking. Despite suffering issues from altitude, exhaustion, and an extremely nasty cough, I still enjoyed every minute of my adventure in the Himalaya, and suspect that any adventurous traveler would feel the same.

China has world’s most polluted city, thanks to coal mining



Cigarettes have gotten really pricey, but here’s a solution: take a trip to China. The city of Linfen, in Shanxi Province, has been named the “world’s most polluted city” by the World Bank, as the air quality is the equivalent of inhaling three packs of cigarettes a day. Coal is China’s main source of energy, and Shanxi Province is the leading coal producer. The same World Bank survey noted that 16 out of 20 of the world’s most polluted cities are in China.

The geniuses at VBS.TV sent a journalist to Linfen (which for some strange reason, has no tourism), to provide a first-person account of what it’s like to spend a day in Smog City. Unsurprisingly, residents have a high rate of lung disease and stomach and lung cancers, but most don’t wear face masks (in contrast to residents in many of Asia’s largest cities). Unfortunately, perma-smog is such a part of daily life, the dire environmental and human health consequences that are the result of coal mining lose their impact. Studies show that particulate from China’s factories and coal mines travels as far as the West Coast of North America.

Linfen serves as yet another heartbreaking reminder that globally, we need to work on reducing our energy consumption, and finding alternative resources. Don’t forget to turn the lights off when you leave.

Summer travel: how not to sizzle your skin

The good folks at CNN have released a helpful guide and accompanying photo gallery horror show of solar ray-blasted epidermis. In “5 ways to avoid getting deep-fried,” you’ll find dermatologist’s tips to protect your sun from UVA/UVB damage, skin cancer detection links, and entertaining anecdotes of CNN reporters’ worst sunburns/precursors to melanoma.

I love the sun as much as most holiday-makers, but years of basting myself in baby oil, combined with the onset of crow’s feet in my early twenties and my mother’s own ongoing struggle with basal and squamous cell carcinomas have turned me into the Queen of Sunscreen. While my friends still mock me, and a former farmers market employer once remarked, “I can always tell when you’ve been hugging my dog, because he smells like sunscreen!” I feel vindicated because at 41, I look a good ten years younger, and have yet to develop my first pre-cancerous lesion. I get an annual screening at my dermatologist, and religiously apply a minimum of SPF 30 UVA/UVB sunblock over all exposed body parts (please remember the back of your neck, hands, ears, and knees, and tops of your feet).

Gadling has a more detailed explanation of what the heck all this SPF stuff means, and a guide to choosing sunglasses that do more than just look hip. I also wear, and heartily endorse (unpaid, of course) the sun protective clothing by ExOfficio, and sun protective hats by Outdoor Research. Sounds wacky, but these items are constructed with UPF (ultraviolet protection factor) textiles that, while not a substitute for sunblock, provide a great dual-defense system. They’re also attractive, and incredibly versatile and travel-friendly. Don’t hide from the sun this holiday weekend; just take precautions, have fun, and think of all the money you’ll save by not requiring reconstructive surgery and Botox.

Healthy travel: a tip list

You can never have too much travel advice, in my opinion. You can have bad travel advice, but the folks at online travel news site eTurboNews have compiled a great list of tips designed to help you keep your arteries unclogged and your spine in alignment while you fly or road-trip this summer. Nothing new or ground-breaking, but definitely worth repeating.

Part of the list is dedicated to finding more nutritious alternatives to fatty, sodium-laden airport and airline fare. Since childhood, I’ve possessed a deep phobia of airline food, so I’ve always brought my own in-flight meals. Now that tight-fisted domestic airlines are depriving passengers of even a bag of pretzels, all the more reason to hit the grocery store the day before you travel. If you frequently travel last-minute, make sure you keep a stash of healthy snacks, such as unsweetened dried fruit, granola bars, or nuts in the pantry so you can grab-and-go.

There’s good advice, too, on little things you can do to avoid tweaking your back or neck, and preventing those unsightly varicose veins. I would add that deep vein thrombosis (DVT) is a much more serious, life-threatening issue on long-haul flights. Get up once an hour and take a lap around the plane, and move your legs by doing some stretches in your seat. Happy, unbloated, limber travels!

Genetically-engineered mosquitoes may help end malaria

Tropical travelers rejoice: researchers are getting closer to finding a possible vaccine for malaria, using genetically-engineered mosquitoes.

The Anopheles stephensi species is one of the main spreaders of human malaria. By altering its salivary glands, the mosquito acts as a “flying vaccinator,” carrying the Leishmania vaccine within its saliva. About 60 species of the Anopheles are vectors of the malaria parasite, which are transmitted to humans when the female feeds on blood.

Tests showed that when an altered mosquito bit its host — in this case laboratory mice — it became a transmitter of the vaccine. The bites succeeded in raising antibodies in the mice, indicating successful immunization with the vaccine.

It’s hoped that continuous exposure to bites will maintain high levels of protective immunity, through natural boosting, for a lifetime.

Researchers hope the vaccinator mosquitoes could be used to formulate a new strategy in the global fight against malaria. Every year about 250 million people are infected with malaria, and nearly one million die, according to the World Health Organization. In Africa, one in every five childhood deaths is caused by malaria.

There are, however, barriers to using this form of vaccination in the wild, including issues of controlling dosage, “medical safety issues” and the “issues of public acceptance to [the] release of transgenic mosquitoes.” It may not be as romantic as sundowners of gin and tonic (quinine is an old school anti-malarial), but it sure beats the potential side effects of Lariam.
