Do harder workouts mean more sweat?

It seems like common sense: if you leave a fitness class looking as though you’ve just ridden a log flume, you’ve probably worked harder than if you’re barely glistening. But that’s not always the case, says Adam Collins, a researcher from the Centre for Nutrition, Exercise and Metabolism at the University of Bath.

Sweating, he says, is part of the thermoregulation process. When your body temperature rises, it signals to your brain to sweat in order to cool you down. As the sweat evaporates, it helps regulate your core temperature.

One reason temperature rises is exercise. “When we exercise, the energy we produce to fuel that activity creates heat as a byproduct,” says Collins. The more intense the workout, the more heat is generated – and usually, the more you sweat. But sweat levels can be misleading.

“There are many other factors that influence how much you sweat,” he adds. These include the temperature of the environment, your clothing and humidity. In humid conditions, sweat evaporates less efficiently, making you feel sweatier than usual, whether or not you’re working hard.

“If you went on an easy run on a hot, humid day, you’d probably sweat a lot,” he says. “But on a cold day, you might run at a much higher intensity and barely sweat at all.”

Sweat also varies from person to person. Your fitness level, age, sex, body size and even whether you’re acclimatised to the climate you’re in all play a role.

So, no, sweat isn’t a reliable measure of how hard you’ve worked out. Better indicators of exertion include how hard you’re breathing, your perceived effort, and your heart rate, which you can track with a chest strap monitor or smart watch. That said, “sweat is a good marker of dehydration”, says Collins. So if you come out of a workout dripping, you’ll need to grab a drink.

Is February 2026 really a once-in -283-years MiracleIn?

A viral message is making the rounds again ahead of February 2026, claiming the month will be a once-in-a-lifetime calendar event — one that ‘only happens once in 823 years.’

The text is usually shared in group chats and social media captions with an urgent tone: February 2026 will have 4 Sundays, 4 Mondays, 4 Tuesdays… and so on, ending with the phrase ‘This is called MiracleIn.’ Some versions even add a superstition-style instruction to forward the message for ‘miracles.’

But fact-checkers and calendar experts say the claim is misleading, and the maths behind it is straightforward.

Why February 2026 isn’t rare

February 2026 has 28 days because 2026 is not a leap year. And a 28-day month is exactly four weeks (28 ÷ 7 = 4).

That means every weekday appears exactly four times in any standard February — which is the normal pattern, not a rare one.

AFP Fact Check has debunked nearly identical claims about February, explaining that in all non-leap years, February naturally contains four of each weekday.

Africa Check also reached the same conclusion, noting that the ‘823 years’ figure is recycled misinformation that resurfaces regularly, often rewritten with a new year.

Timeanddate.com, which has repeatedly tracked these calendar rumours, lists the February ‘MiracleIn’ message as a false viral claim and explains that the weekday pattern is simply what happens when February has 28 days.

What about the ‘MiracleIn’ part?

The term ‘MiracleIn’ has no recognised scientific or calendar meaning. One widely shared version also suggests February 2026 will include a 25-hour day, which fact-checkers say is not a global phenomenon.

In short: February 2026 is not a rare ‘miracle month.’ It’s a standard February — and the viral message is another recycled calendar myth dressed up as a once-in-centuries event.

465m-year-old horseshoe crab fossils found in AlUla

The Royal Commission for AlUla has announced the documentation and publication of a rare fossil discovery of horseshoe crabs dating back approximately 465 million years, following a peer-reviewed scientific study published in the geology journal Gondwana Research.

The discovery, published for the first time at a global level, strengthens AlUla’s standing as an international centre for geological and scientific research related to Earth’s history and biodiversity. The fossils were uncovered in the Gharameel Nature Reserve in AlUla.

Dating to the Middle Ordovician period, roughly between 485 and 444 million years ago, the fossils are among the oldest known horseshoe crab specimens worldwide. They are distinguished by their unusually large size compared with other species from the same era. All specimens were found preserved upside down, a mode of fossilisation not previously recorded, alongside trace fossils indicating attempts by the organisms to right themselves

Geological layer analysis suggests the area was subject to repeated strong seasonal storms, indicating that these ancient creatures gathered in shallow coastal environments affected by such events, which contributed to their preservation within sedimentary deposits.

The findings provide a clearer picture of AlUla’s ancient environment as a coastal region and add a new scientific dimension to understanding its geological and environmental history. The commission said the analysis demonstrates its ability to generate accurate data that supports scientific research and innovation.

The discovery also represents a previously undocumented species that has yet to be formally classified. Research has been conducted in two phases in collaboration with a team led by Dr Russell Bicknell of Flinders University. The second phase, scheduled for the first half of 2026, will involve the collection of additional samples and further study prior to official classification. The fossil samples have been preserved within the commission’s museum collections to support future research and public engagement.

The commission said the discovery reflects its commitment to advancing scientific research and reinforcing AlUla’s position as a global destination for geological discovery, international collaboration and education linked to natural heritage, in line with the objectives of Saudi Vision 2030.
