Altitude sickness isn’t just an Everest problem. It’s a risk for any hiker venturing into high country above 3,000 meters (9,842 feet), from the Rockies and Andes to the Himalayas. Mountaineers and high-altitude climbers have understood this for decades: success at altitude isn’t about strength alone, but about pacing, acclimatization, and knowing when to stop.

Those same lessons apply directly to trekkers heading for Everest Base Camp (EBC). You can train for months, buy the best gear, and still get humbled by one thing on the trek to Everest Base Camp: altitude. One day you feel strong and excited. The next morning you wake up in Namche Bazaar (3,440 meters / 11,286 feet) with a pounding headache, no appetite, and legs that suddenly feel heavy. That’s altitude sickness, and it’s the reason many trekkers turn back before they ever reach Base Camp.

The good news? Altitude sickness is often preventable. Not with “super fitness,” but with smart pacing, proper acclimatization, good daily habits, and the right decisions at the right time.

This guide breaks everything down in a clear, practical way: what altitude sickness is, why it happens on the Everest Base Camp route, how to acclimatize properly, what symptoms to watch for, and what to do if you feel unwell. Follow these principles, and you’ll give yourself the best chance of reaching Everest Base Camp safely, and actually enjoying the journey.

What Is Altitude Sickness and Why Is It a Concern on the Everest Base Camp Trek?

Altitude sickness, also known as Acute Mountain Sickness (AMS), occurs when your body doesn’t have enough time to adapt to lower oxygen levels at high elevation. According to the Himalayan Rescue Association, symptoms can range from mild discomfort to life-threatening conditions if ignored.

It usually starts mild, but it can escalate quickly.

The three types you should know

AMS (Acute Mountain Sickness): AMS, the most common form, begins with dizziness and difficulty sleeping; the key is recognizing AMS early so it doesn’t progress.
HAPE (High Altitude Pulmonary Edema): This condition happens when fluid builds up in the lungs, making breathing difficult even at rest. Additional oxygen and medication are needed.
HACE (High Altitude Cerebral Edema): An urgent medical emergency requiring immediate evacuation, HACE involves swelling of the brain that causes confusion and loss of coordination.

Why Altitude Sickness Is Common on the EBC Route

Everest Base Camp sits at 5,364 meters (17,598 feet). At this altitude, oxygen availability is roughly 50% of sea-level concentrations, according to data summarized by the CDC’s High-Altitude Travel Guidelines.

You can’t “power through” that change. Your body needs time.

The EBC trek adds extra stressors:

Long walking days
Cold temperatures
Dehydration (very common at altitude)
Poor sleep in teahouses at higher villages

These same challenges become even more pronounced for trekkers who combine the trek to Everest Base Camp with climbing Island Peak Nepal, where altitude exposure is higher and recovery margins are tighter.

Altitude sickness has nothing to do with strength. Even very fit trekkers can develop AMS if they ascend too quickly.

When Altitude Sickness Usually Starts on the Trek

Symptoms often appear above 2,500 meters (8,200 feet). On the EBC trek, this can happen quickly, especially after reaching Namche Bazaar.

Higher-risk points along the journey include:

Namche Bazaar (3,440 meters / 11,286 feet)
Dingboche (4,410 meters / 14,468 feet)
Lobuche (4,940 meters / 16,207 feet)
Gorak Shep (5,164 meters / 16,942 feet)

From around 3,000 meters (9,842 feet) onward, doing a short body check every evening becomes essential.

How to Prepare for Altitude Before the Everest Base Camp Trek

A smoother trek starts before you even land in Nepal. Preparation won’t guarantee you avoid AMS, but it helps your body cope better with stress and fatigue.

Get Your Body Trek-Ready

Aim for 8–12 weeks of training, including:

Uphill hiking (stairs, hills, treadmill incline)
Long walks for endurance
Leg and core strength training
Practice hikes with a backpack

Fitness won’t prevent altitude sickness, but it reduces overexertion, which does lower risk. This becomes especially important if your itinerary includes Island Peak climbing after Everest Base Camp, where accumulated fatigue can increase susceptibility to AMS.

Medical Check-Up

Before you travel to high-altitude destinations, speak to a medical professional if you have:

Asthma or lung conditions
Heart issues
Previous history of altitude sickness
Concerns about taking Diamox

Also ensure your travel insurance covers high-altitude trekking and helicopter evacuation, particularly if you plan additional objectives like peak climbing.

The Best Acclimatization Techniques for the EBC Trek

If there’s one rule that saves trekkers every season, it’s this:

Go slow—especially above 3,000 meters (9,842 feet). A safe itinerary includes at least two key acclimatization days:

Namche Bazaar (3,440m / 11,286 ft)
Stay two nights. Do a day hike to Everest View Hotel or Khumjung, then sleep back in Namche.

Dingboche (4,410m / 14,468 ft)
Stay two nights. Hike to Nagarjun Hill or the Chhukung ridge area, then descend to sleep.

These aren’t “rest days”, they’re altitude training days. Skipping them is one of the most common mistakes trekkers make, especially those planning to continue on to Island Peak after the EBC trek.

Hike to a higher point during the day, then return to a lower elevation to sleep. Keep acclimatization hikes steady and controlled, not exhausting missions.

Medications for Altitude Sickness: What Actually Helps

Diamox is commonly used to help with acclimatization by improving breathing at altitude. Medical guidance from sources such as the Mayo Clinic and CDC recommends it only under professional advice.

A typical preventative dose:

125 mg twice daily, starting 1–2 days before ascent or early in the trek
(always follow medical advice)

Diamox can help, but it never replaces proper acclimatization or descent if symptoms worsen.

Natural remedies, such as garlic soup, ginger tea, and warm fluids, can improve comfort and hydration. However, they do not replace slow ascent, acclimatization days, or descent, especially at higher elevations encountered during Everest Base Camp trekking and Island Peak climbing.

Symptoms of Altitude Sickness: What to Watch For

Early Warning Signs (AMS)

Persistent headache
Nausea or loss of appetite
Unusual fatigue
Dizziness
Poor sleep

If symptoms are mild, do not ascend further until they improve.

Dangerous Symptoms (Medical Emergency)

According to the International Society for Mountain Medicine:

Breathlessness at rest
Confusion or unusual behavior
Poor coordination
Persistent cough or chest tightness

These require immediate descent and medical attention.

What to Do If You Get Altitude Sickness on the Trail

If symptoms are mild:

Rest at the same altitude for 24 hours
Hydrate and eat light, high-carb meals
Reassess the next morning

If symptoms persist or worsen:

Descend at least 300–500 meters (1,000–1,640 feet)

No summit, no Base Camp photo, and no peak climb is worth risking your life.

Medical Support on the EBC Trail

The Himalayan Rescue Association clinic in Pheriche, seasonal service, is the most-known medical support point. Some lodges have oxygen or emergency resources, but availability varies, another reason proper insurance is essential.

Daily Habits That Make a Huge Difference

Hydration & Food

Drink 3–4 liters of fluids daily
Eat high-carb meals (rice, pasta, potatoes, lentils)
Snack regularly, appetite often drops at altitude

Dehydration makes AMS worse quickly.

Pace: Slow Beats Strong

Walk with:

Steady breathing
Short breaks
No rushing or racing others

A slow trekker reaches Base Camp more often than a fast trekker who crashes in Dingboche.

Avoid These at Altitude

Alcohol
Smoking
Sleeping pills or sedatives

They reduce oxygen efficiency and worsen sleep quality.

Should You Hire a Guide to Reduce AMS Risk?

A good guide helps by controlling the pace of your trek and can help with:

Monitoring symptoms
Managing accommodations
Making tough calls to stop when trekkers want to push on

A knowledgable guide becomes especially important if you plan to combine the trek to Everest Base Camp with climbing Island Peak in Nepal, where acclimatization margins are tighter. If you’re unsure about altitude, hiring a guide is one of the smartest safety upgrades you can make.

Learn From Experience

If there’s one thing experienced Himalayan guides agree on, it’s this: your itinerary matters more than your fitness. You can be strong, fast, and well-trained, but if you rush the ascent, altitude sickness can still catch you off guard.

Rest days in Namche Bazaar and Dingboche aren’t optional. They’re essential for a safe Everest Base Camp trek and absolutely critical if you plan to continue on to Island Peak.

Mild AMS is a warning, not something to push through. Severe symptoms are emergencies that require immediate descent. Knowing the difference can prevent serious consequences.

And finally, remember that descending is not failure. It’s smart decision-making. Everest Base Camp, and even Island Peak, are incredible goals, but real success is returning healthy, with clear memories and respect for the mountains that allowed you to experience them.

The Best Sustainable Dresses Brands of 2026 — for Any Budget

What’s not to love about a go-to dress in your wardrobe? The right one can be dressed up or down, it can be worn alone, or worn as a skirt with the right top layered on. A dress is arguably the easiest outfit to put together that still looks put together. The right sustainable dress is the kind of closet staple you can reach for on any kind of summer day, even when you have no idea what to wear.

From t-shirt dresses and house dresses to chic midi frocks and fun mini’s for a night out, this roundup of sustainable dresses has just about everything.

So if you’re looking for that perfect eco-friendly dress to complement your wardrobe this year, I’ve got you covered with this guide to sustainably and ethically-made dresses. This guide has brands with both casual and more formal dresses, but if you’re shopping for exclusively special occasion dresses, I’d recommend also browsing my guide to formal dresses.

What Qualifies As (More) Sustainable Dresses?

Wearing what we have in our closets is the most sustainable approach! But if you’re here, you probably already evaluated that option and you’re looking to add something fresh to your closet.

Secondhand Dresses are Sustainable Dresses

The second most sustainable option is to look secondhand. ThredUp can be a versatile option for pieces at any price point and The RealReal is my favorite choice for more premium brands.

Online secondhand marketplaces like Poshmark or Depop are also good options — but something to watch out when it comes to peer-to-peer marketplaces is that they can sometimes contain new fast fashion disguised as “vintage” pieces, so it can require some additional digging.

For more suggestions, find my full guide to secondhand clothing retailers in this post.

If you’re looking for a new sustainably-made dress, here are some considerations:

Materials: what is it made from? Is it made with a natural fabric like hemp, linen, or organic cotton? Perhaps made from deadstock or upcycled materials?
Production Practices: does the brand take efforts to not overproduce? Do they produce in small batches? (No matter how “eco-conscious” the material is, if a brand is throwing away 30% of their stock, that’s not sustainable!)
Timelessness and Quality: this doesn’t have to mean boring and doesn’t necessarily mean the brand never participates in a trend. But does the brand constantly hop on every single trend and push you to buy more and more? Or do they encourage slow mindful consumption with well-designed dresses? Do they pay attention to construction and details that ensure you’ll be wearing this dress year after year?
Manufacturing: most brands do not produce their own clothing, but are they sourcing from facilities that pay their workers fairly? Do those facilities minimize waste, use renewable energy, and responsibly manage chemical usage?
Ethical Production: who made the dress? were they paid fairly and were they working in safe conditions? do they have worker’s rights, such as the right to organize? how does the brand ensure this? Certifications can be helpful here. But sometimes factories cannot afford these, so look for other assurances, such as that the founder personally visits the factories.
Ownership: is it a small woman-owned business or major fashion brand owned by billionaires? What are your values when it comes to where your money is going?

I know that’s a lot! But these are elements to start looking for as you browse through brands. This isn’t about perfection — it’s just about learning and doing the best we can.

My Top Picks for Ethical and Sustainable Dresses

To help you out (because I get it — it’s complicated!) I’ve curated retailers and brands with sustainable and ethical dresses. These brands aren’t necessarily perfect, but they’re doing things better for people and the planet. I’ve included “Conscious Qualities” by each brand or retailer, so you can get an idea about why the brand is on the list and which sustainability criteria they meet.

I’ve also curated brands at a range of price points, to accommodate for different budgets.

This Guide’s Price Range Key:

$ = Dresses under $100
$$ = Dresses $100 – $200
$$$ = Dresses $200+

Keep in mind that while price and quality aren’t necessarily directly tied to each other, lower prices may sometimes mean a sacrifice on quality and the highest quality picks are often on the higher end of the price spectrum. Better quality fabrics cost more, more skilled seamstresses are typically paid more, and many of the details that take a piece from good to great — such as pockets, well-fastened buttons, and linings — add to the product cost as well.

As always, we only feature brands that meet high standards for sustainability that we love and that we think you’ll love too!

You Might Also Be Wondering…

Are sustainable dresses worth the higher price tag?

It depends! The key here is to look at cost-per-wear. A $250 organic linen dress you wear 80 times costs $3.12 per wear. A $40 fast fashion dress you wear 5 times costs $8 per wear. More sustainable dresses tend to have timeless design and be made with higher quality materials and construction, meaning they last longer, hold their shape better, and don’t need replacing as often. That said, always look at the care instructions! Natural fibers may require a bit more attention than synthetic fibers (such as air-drying instead of throwing in a machine dryer) but they’re well worth the additional effort.

And there are also genuinely affordable sustainable options (like No Nasties and tentree) that prove sustainability doesn’t always mean expensive. Some brands are priced very competitively with their less sustainably-minded couterparts.

What certifications should I look for when buying a sustainable dress?

The most meaningful certifications for dresses are:

GOTS (Global Organic Textile Standard) for organic fibers and other sustainability assurances during production
OEKO-TEX STANDARD 100 for chemical safety in finished garments (note that this is a product certification, not a material certification — and many brands miscommunicate this label)
Made in Fair Trade Certified factories which ensure that the brand is paying into a premium that goes to a Community Development Fund that workers can vote on to determine how to use those funds

However, many small brands cannot afford to buy certified products, fabrics, or pay into fair trade programs. There are other ways to ensure ethical sourcing as well, so look into a brand’s sustainability or sourcing pages too.

What’s the most sustainable type of fabric for a dress?

This is a nearly impossible question to answer because no single fiber is the “best” by all measures. There are so many considerations (land use, water use, biodegradability, longevity, carbon emissions, and so on) that I cannot tell you the single “best” fiber.

That said, I avoid synthetic materials, which are made from fossil fuels and release microplastics into our environment when washed. Among natural options, different fibers have different use cases, so I recommend looking for the best version of each. This deep dive has much more on fabrics.

But even then there are nuances — is 50% organic cotton blend with hemp or linen better than a 100% conventional cotton fabric considering that monofiber fabrics are much easier to recycle at the end of their life? As you can see, the most sustainable question is complicated.

Should I buy secondhand instead of new sustainable dresses?

From a pure environmental standpoint, secondhand is almost always the better choice — no new resources used, no new manufacturing emissions. Platforms like ThredUp, The RealReal, Poshmark, and Depop are great starting points. That said, buying new from sustainably-minded brands does serve a purpose: it signals market demand for responsible production and can support artisans, ethical manufacturers, and/or women-owned small businesses, depending on the brand. The best approach in my mind? Check secondhand first. If you can’t find what you need, then invest in a quality piece from a trusted more sustainable brand if you can.

What sustainable dresses come in plus sizes or extended sizes?

Size inclusivity is an area where sustainable fashion has historically underperformed — but it’s improving. LOUD BODIES is the standout on this list, offering 15 sizes from XXS to 10XL. Christy Dawn goes up to 3XL in some styles, Míe up to 3XL, and Tradlands to 4XL. When shopping, always check the full size range on the brand’s website, as some brands offer extended sizes only in select styles.
