When the Conference on Heat Was Cancelled Because of Heat
Ancient ways to cool down, and the why behind them
This week, a London Climate Action Week event on adapting to extreme heat was cancelled - because of extreme heat. A red Met Office warning, temperatures pushing past 40°C in parts of Europe, and the irony wrote itself: the very crisis the event was convened to address made it impossible to hold.
It's a small, sharp image of where we are. Along with every effort to cut emissions and shift away from fossil fuels — work that remains non-negotiable — we also need to relearn something we've largely forgotten: how to live alongside heat without simply reaching for more energy-hungry machines to fight it. Air conditioning has its place, but it can't be the only answer; it strains the grid, intensifies urban heat islands, and isn't available to everyone who needs relief.
So alongside the long-term work, here is some shorter-term wisdom — drawn from indigenous and ancestral knowledge across cultures, and from the people in my own life — on how to cool the body when the air itself offers no relief.
Why These Work
Before the techniques themselves, it's worth understanding *why* they work — because none of this is 'just' folklore. The body has specific zones built for rapid heat exchange: the wrists, neck, temples, inner elbows, behind the knees, armpits, and groin all carry blood close to the skin's surface. Cool these areas and you cool the blood moving through them, which circulates that relief through the whole body.
Evaporation adds a second mechanism: water drawn off the skin pulls heat with it as it turns to vapour, which is exactly what sweat does naturally. And pace matters too: many hot-climate cultures favour slow, deliberate movement in heat, not from lack of urgency, but because moving fast simply generates more internal heat to dissipate.
How: Body Cooling Practices
Cool water on the wrists
A simple, immediate one — running cold water over the wrists exploits the same close-to-skin blood vessels mentioned above. This is something I learned growing up in South Africa, where managing real heat was simply part of daily life.
Cold, wet flannel or towel around the neck
Draped at the nape, where it cools blood feeding directly to the brain. As it slowly dries, the evaporation adds a second layer of relief. Passed on to me by my friend Dorothea after a long, hot day last year.
Cold flannel on the belly
Our tummies carry good surface blood flow too, making it a quietly effective spot. I learned this from a homeopath who treated me for childhood asthma in South Africa.
Hot tea, not iced drinks
Counterintuitive, but many hot-climate cultures favour warm tea over something icy. The reasoning: a hot drink triggers the body's actual cooling mechanism: sweating, rather than offering only a brief, surface-level chill.
Another from South Africa, where this was just how things were done. (Although any hydration is good, so iced drinks, something with a bit of salt in like a lassi, or low/no alcohol lagers, all very good too!)
Misting spray, chilled
A small spray bottle kept in the fridge (or briefly in the freezer) combines cold and evaporation in one go. A fast, portable version of the same principle. This is my current favourite - I've co-opted one of my watercolour spray bottles for this.
Cool foot soaks
Feet carry a dense network of blood vessels, and cooling them can lower core body temperature more effectively than people expect.
Cooling foods
Cucumber, mint, watermelon, coconut water — foods long categorised as "cooling" within Ayurvedic and Traditional Chinese Medicine frameworks.
Slowing down
Perhaps the hardest one in a culture built around productivity: simply moving slower in the heat, resting in the hours it peaks, and treating that rest as practical wisdom rather than idleness.
A Breath of Water - A Small Act of Cooling
The painting above is offered in that same spirit, as a small, accessible act of nervous-system regulation. Sometimes the body needs water on the skin; sometimes it needs water for the eyes to rest in. Both are part of how we get through what's coming, together, and how we honour the people, near and far, who already knew how.
