A physiologist went looking for the origin of the rule in 2002 and came back empty. What the reference intakes actually say, why food and coffee count, how much the number varies between people, and when in a Gulf summer it genuinely matters.

The standard aluminium 80 is negatively buoyant full and positively buoyant empty, which is why safety stops go wrong at the end of a dive. Steel behaves differently, and the valve and testing rules differ too.

Heat, sweat, hard water and relentless sun age a wardrobe faster than wear does. Most of the damage is preventable, and almost all of it comes down to washing habits rather than fabric choice.

Wheat and oat yields are poor, livestock farmers are eating into winter feed in August, and growers are running out of irrigation water. The Farmers' Union calls this the third drought in five years.

Dahab's Blue Hole draws freedivers year round for a reason: shore access to real depth, warm water, forgiving conditions and an established training community.

Three thousand Dutch adults who ended their showers cold took fewer sick days. A 2025 review of eleven trials found stress fell twelve hours after a plunge and inflammation rose. What is known, what is marketing, and why the first minute can kill.

Overweighting is the most common equipment error in freediving and the one with the worst failure mode. The rule is simple: neutral at ten metres, positive above it, and the surface is where it matters.

Safety divers, counterballast lines and strict medical protocol turned a high risk sport into one of the most closely supervised in the water.

It has an authorised FDA health claim, which almost no supplement does, and meta-analyses behind it for cholesterol, blood glucose and constipation. One gel-forming property explains all three, and so does the way it goes wrong.

Layered filo, clarified butter, crushed nuts and syrup. It is not a difficult dessert, it is a patient one, and the single thing that decides crisp or soggy happens in the last thirty seconds.

Three Egyptian dive bases, three different Red Seas. Here is what Hurghada, Sharm el-Sheikh and Dahab each actually deliver underwater.

Rice porridge simmered until the grains dissolve is the convalescent food of East Asia, and kitchari is its equivalent in India. Adding turmeric and ginger to congee simply puts the two traditions in the same bowl.

Fruit contains sugar, so the advice writes itself and it is wrong. The relevant distinction is not sweet versus not sweet. It is whether the sugar is still inside a structure that has to be dismantled before it can be absorbed.

The grinder matters more than the brewer, freshness matters more than origin, and the ratio matters more than technique. Three fixes that cost less than one machine and change more.

Heat illness is one of the most preventable medical emergencies there is, and most of the popular advice about it is either useless or actively wrong. The humidity is what changes the arithmetic.

Oman splits its diving into two distant reserves, one a protected reef north of Muscat, the other a remote wreck-strewn archipelago in the south.

Glasses do not fit under a mask, so the default answer is contact lenses. Eighty-five per cent of cases of a rare blinding corneal infection occurred in lens wearers who swam or dived in them, and there is a better option most divers never price.

One demands breath control and stillness, the other demands equipment discipline. Here is what separates them and where beginners should start.

Most filo is already vegan. Swap clarified butter for a blend of coconut oil and olive oil, use sugar syrup instead of honey, and the result is genuinely crisp rather than merely acceptable.

The old assumption was that one breath cannot load enough nitrogen to matter. Repetitive deep dives with short surface intervals disprove it, and the divers it happens to are usually working, not competing.

Traditional Arab screens get praised in general terms and tested rarely. Field studies in hot climates put a figure on what they do, and the figure is real, useful, and smaller than the romantic version of the story suggests.

Raja Ampat remains one of diving's richest destinations, but current, season, permits and mounting pressure from tourism and mining belong in the booking decision.

MNDF Sergeant Major Mohamed Mahudhee died searching a Maldives cave for five missing divers. His death shows the risk that recovery divers accept on behalf of strangers.

New resorts, new dive licences and a scaled-back masterplan. Here is the real state of Saudi Arabia's Red Sea diving push, not the pitch deck version.
Feb 10, 2026

Every restrictive plan produces results in the first month, including plans that contradict each other completely. That is a fact about restriction, not about the theory attached to it.

Day 187 brought more reporting on efforts to reopen the Strait of Hormuz. The transit count on the latest published day was six, against a pre-war baseline of about 85 a day, and the market puts one percent odds on normal traffic by 15 September.

The Philippines' remote World Heritage reef rewards careful planning with walls, sharks, turtles and a conservation model built around a short liveaboard season.

Whole aubergines split, stuffed with slow-cooked onion, garlic and tomato, and braised in olive oil until collapsing. Served at room temperature, entirely vegan, and one of the great dishes of the Ottoman kitchen. The legend, the method, and the oil.

A global cafe boom collided with a limited Japanese harvest, and now matcha lattes are getting rationed, waitlisted, and quietly more expensive.

WHO guidance targets free sugars, not all sugar. The distinction changes how a bowl of cereal or a smoothie should be judged.

Most adults eat about half the fibre they need. The gap matters more than dieters realise, and closing it is not about bran.

Drone strikes on AWS data centers in the UAE and Bahrain marked the first military attack on hyperscale cloud infrastructure, forcing a new kind of reckoning.

Three constructions account for nearly every leather shoe sold. One can be resoled indefinitely, one can be resoled a few times, and one is thrown away when the sole wears through. How to tell which you are holding.

SpaceX completed SES's medium-orbit constellation on a booster flying for the twenty-ninth time. Vega-C put FLEX, the first satellite built to watch photosynthesis, into orbit with Sentinel-3C. And a Red Sea state became the seventy-second signatory.

Full grain, top grain, corrected, split, genuine, bonded and vegan describe seven different materials, some of them barely related. What each one is, how it will age, and how to tell them apart in the shop.

The agencies argue endlessly and the accident data barely distinguishes between them. Here is what genuinely differs, what does not, and the questions to ask a dive centre before you pay.

A war that closed the Strait of Hormuz and hit every GCC state should have broken the region's economics. Reserves and diversification kept it standing.

Peptide is a chemical category, not a claim. The two versions most people actually buy are the ones with the least regulation and, oddly, the best safety record. Here is what the trials support and what physics gets in the way of.

At Big 5 Global 2025 in Dubai, Al Wisam put SIRL, Batmatic, and Battipav equipment in front of contractors looking for practical site solutions.

The version most of the world eats is the Levantine one, and it is a revision. Egypt still makes it the older way, with fava beans, under a different name. The argument about who owns it is genuinely political.
Aug 21, 2026

A potential war is the wrong frame. Fighting began on 28 February and the strait closed on 4 March. The economic damage is real and measurable, and it is far smaller than the forecasts issued in the first month, for reasons worth understanding.
