Be it on Mount Kilimanjaro, in the Andes, Himalayas or somewhere else, mountaineering can give you an unforgettable high. But it comes with a risk that's often underestimated though: altitude sickness.

According to the German press agency (dpa), climbing too quickly can cause serious health problems, experts said.

“The risk of getting altitude sickness significantly increases at an elevation of about 2,500 meters,” said Dr. Tomas Jelinek, scientific director of Germany's Center for Travel Medicine (CRM).

Symptoms include headache, nausea, fatigue and dizziness.

Depending on the region, the number of affected climbers can be quite high.

According to the CRM, as many as 21% of climbers develop symptoms in Nepalese high mountain areas, and from 45 to 75% on Kilimanjaro.

“Altitude sickness is a serious but avoidable problem,” remarked Jelinek, the cause of which is lower oxygen levels in the ambient air: at 5,000 meters they're only about half those at sea level.

“The most effective way to prevent it is to take precautions,” he said.

He recommended that mountaineers plan their climbing tour carefully, get travel medicine advice before setting off and critically examine bookable tours - also with an eye to the ascent profile of the climb.

To help your body adapt to lower oxygen levels, Jelinek said it's good to prepare with high-elevation day treks so long as you sleep at lower elevations afterwards.

Train high, sleep low, in other words.

Rest for a day after every elevation gain of 1,000 meters at the latest.

Beginning at an elevation of 2,500 meters, the elevation at which you sleep shouldn't increase more than 300 to 600 meters daily.

And be sure to drink sufficient fluids, since dehydration can aggravate altitude sickness symptoms.

Increased breathing and heart rates are a normal reaction when acclimating to mountain ascents and have no pathological significance, according to the Institute of International Health at Charité University Hospital in Berlin.

Experts there said signs of an early stage of altitude sickness are headache, nausea and vomiting, fatigue, loss of appetite, dizziness and difficulty sleeping.

If you have symptoms such as headache or dizziness, which usually occur six to 12 hours after quick climbs at elevations over 2,000 meters, you should stop your ascent. The symptoms then typically disappear within one to three days.

If they don't, or your condition worsens, you should descend immediately. The symptoms generally abate after an elevation drop of 500 to 1,000 meters, the health experts said.

In severe cases, you should receive medical assistance if possible. Transport to lower elevations is then imperative. At worst, altitude sickness can be life-threatening, causing your lungs to fill with fluid or your brain to swell.

The experts also pointed out that certain medications, such as acetazolamide and dexamethasone, can help prevent symptoms of altitude sickness. Both are available by prescription only.

Egypt on Sunday revealed the revamp of two colossal statues of a prominent pharaoh in the southern city of Luxor, the latest in the government’s archaeological events that aim at drawing more tourists to the country.

The giant alabaster statues, known as the Colossi of Memnon, were reassembled in a renovation project that lasted about two decades. They represent Amenhotep III, who ruled ancient Egypt about 3,400 years ago.

“Today we are celebrating, actually, the finishing and the erecting of these two colossal statues,” Mohamed Ismail, secretary-general of the Supreme Council of Antiquities, told The Associated Press ahead of the ceremony.

Attempts to revive a prestigious temple Ismail said the colossi are of great significance to Luxor, a city known for its ancient temples and other antiquities.

They’re also an attempt to “revive how this funerary temple of king Amenhotep III looked like a long time ago,” Ismail said.

Amenhotep III, one of the most prominent pharaohs, ruled during the 500 years of the New Kingdom, which was the most prosperous time for ancient Egypt.

The pharaoh, whose mummy is showcased at a Cairo museum, ruled between 1390–1353 BC, a peaceful period known for its prosperity and great construction, including his mortuary temple, where the Colossi of Memnon are located, and another temple, Soleb, in Nubia.

The colossi were toppled by a strong earthquake in about 1200 BC that also destroyed Amenhotep III’s funerary temple, said Mohamed Ismail, secretary-general of the Supreme Council of Antiquities.

They were fragmented and partly quarried away, with their pedestals dispersed.

Some of their blocks were reused in the Karnak temple, but archaeologists brought them back to rebuild the colossi, according to the Antiquities Ministry.

In late 1990s, an Egyptian German mission, chaired by German Egyptologist Hourig Sourouzian, began working in the temple area, including the assembly and renovation of the colossi.

“This project has in mind ... to save the last remains of a once-prestigious temple,” she said.

The statues show Amenhotep III seated with hands resting on his thighs, with their faces looking eastward toward the Nile and the rising sun. They wear the nemes headdress surmounted by the double crowns and the pleated royal kilt, which symbolizes the pharaoh’s divine rule.

Two other small statues on the pharaoh’s feet depict his wife, Tiye.

The colossi — 14.5 meters (48 feet) and 13.6 meters (45 feet) respectively — preside over the entrance of the king’s temple on the western bank of the Nile.

The 35-hectare (86-acre) complex is believed to be the largest and richest temple in Egypt and is usually compared to the temple of Karnak, also in Luxor.

The colossi were hewn in Egyptian alabaster from the quarries of Hatnub, in Middle Egypt. They were fixed on large pedestals with inscriptions showing the name of the temple, as well as the quarry.

Unlike other monumental sculptures of ancient Egypt, the colossi were partly compiled with pieces sculpted separately, which were fixed into each statue’s main monolithic alabaster core, the ministry said.

Sunday’s unveiling in Luxor came just six weeks after the inauguration of the long-delayed Grand Egyptian Museum, the centerpiece of the government’s bid to boost the country’s tourism industry. The mega project is located near the famed Giza Pyramids and the Sphinx.

“This site is going to be a point of interest for years to come,” said Tourism and Antiquities Minister Sherif Fathy, who attended the unveiling ceremony. “There are always new things happening in Luxor.”

A record number of about 15.7 million tourists visited Egypt in 2024, contributing about 8% of the country’s GDP, according to official figures.

Fathy has said about 18 million tourists are expected to visit the country this year, with authorities hoping for 30 million visitors annually by 2032.

National Wildlife Center Launches 2nd Phase to Regulate Unlicensed Species in Saudi Arabia

National Wildlife Center Launches 2nd Phase to Regulate Unlicensed Species in Saudi Arabia

The National Center for Wildlife (NCW) has launched the second phase of its initiative to regulate the status of unlicensed wildlife species in the Kingdom, representing one of the most prominent national efforts to control wildlife possession, document ownership, and ensure that all practices related to housing, breeding, and trading comply with the Environmental Law and its implementing regulations, according to SPA.

The regularization period extends until the end of February 2026 and targets those who keep or handle wildlife on a large scale, including private collections (farms) containing more than 10 species, facilities engaged in breeding and housing wildlife, and businesses involved in selling wildlife products or derivatives.

This phase follows the success of the first, which focused on regulating the status of falcons, and reinforces the Kingdom's role in curbing illegal practices that could harm natural environments or threaten the survival of wildlife species. The initiative reflects a growing national commitment to protecting biodiversity and developing a more regulated system for managing wildlife within the Kingdom.

The regulation aims to build an accurate database of wildlife, enhance monitoring, and improve housing standards in accordance with environmental and health considerations.

The NWC emphasizes that this step aligns with national efforts to protect wildlife, support ecosystem sustainability, and address the challenges of illegal wildlife trafficking. It calls on all owners and relevant facilities to take advantage of the grace period, review the regulations through the "Fitri" platform, and contribute to a safer and more balanced ecosystem

Truck driver Muhammad Afzal was not expecting to be stopped by police, let alone fined, as he drove into Islamabad this week because of the thick diesel fumes emanating from his exhaust pipe.

"This is unfair," he said after being told to pay 1,000 rupees ($3.60), with the threat of having his truck impounded if he did not "fix" the problem.

"I was coming from Lahore after getting my vehicle repaired. They pressed the accelerator to make it release smoke. It's an injustice," he told AFP.

Checkpoints set up this month are part of a crackdown by authorities to combat the city's soaring smog levels, with winter months the worst due to atmospheric inversions that trap pollutants at ground level.

"We have already warned the owners of stern action, and we will stop their entry into the city if they don't comply with the orders," said Dr Zaigham Abbas of Pakistan's Environmental Protection Agency (EPA), as he surveyed the checkpoint at the southeast edge of the capital.

For Waleed Ahmed, a technician inspecting the vehicles at the site, "just like a human being, a vehicle has a life cycle. Those that cross it release smoke that is dangerous to human health".

While not yet at the extreme winter levels of Lahore or the megacity Karachi, where heavy industry and brick kilns spew tons of pollutants each year, Islamabad is steadily closing the gap.

So far in December it has already registered seven "very unhealthy" days for PM2.5 particulates of more than 150 micrograms per cubic meter, according to the Swiss-based monitoring firm IQAir.

Intraday PM2.5 levels in Islamabad often exceed those in Karachi and Lahore, and in 2024 the city's average PM2.5 reading for the year was 52.3 micrograms -- surpassing the 46.2 for Lahore.

Those annual readings are far beyond the safe level of five micrograms recommended by the World Health Organization.

Built from scratch as Pakistan's capital in the 1960s, the city was envisioned as an urban model for the rapidly growing nation, with wide avenues and ample green spaces abutting the Himalayan foothills.

But the expansive layout discourages walking and public transport remains limited, meaning cars -- mostly older models -- are essential for residents to get around.

"The capital region is choked overwhelmingly by its transport sector," which produces 53 percent of its toxic PM2.5 particles, the Pakistan Air Quality Initiative, a research group, said in a recent report.

"The haze over Islamabad... is not the smoke of industry, but the exhaust of a million private journeys -- a self-inflicted crisis," it said.

Announcing the crackdown on December 7, EPA chief Nazia Zaib Ali said over 300 fines were issued at checkpoints in the first week, with 80 vehicles impounded.

"We cannot allow non-compliant vehicles at any cost to poison the city's air and endanger public health," she said in a statement.

The city has also begun setting up stations where drivers can have their emissions inspected, with those passing receiving a green sticker on their windshield.

"We were worried for Lahore, but now it's Islamabad. And that's all because of vehicles emitting pollution," said Iftikhar Sarwar, 51, as he had his car checked on a busy road near an Islamabad park.

"I never needed medicine before but now I get allergies if I don't take a tablet in the morning. The same is happening with my family," he added.

Other residents say they worry the government's measures will not be enough to counter the worsening winter smog.

"This is not the Islamabad I came to 20 years ago," said Sulaman Ijaz, an anthropologist.

"I feel uneasy when I think about what I will say if my daughter asks for clean air -- that is her basic right."
