Yes — or at least it feels that way. Blood vessels run very close to the surface of the skin at the wrist, so pressing something cold there may cool the blood flowing through them and help lower your body temperature from the inside. Whether the effect is physiological or partly placebo remains uncertain, but the technique is low-risk and widely reported to bring relief.
The wrist is one of the few places on the body where major blood vessels sit just beneath the skin with minimal insulating tissue above them. That proximity is exactly why the technique is suggested: cold applied there has a more direct path to the bloodstream than it would on, say, the forearm or the thigh.
Bill Clapson raised this tip on The Toddle About Show during a heatwave episode recorded in early July 2026 — a summer during which his family had already experienced four heatwaves before August. The context was very real: managing heat discomfort for the whole household, including two young daughters, Florence and Aurora, aged eight and six.
Clapson and his co-host Emily Clapson were deliberate about not overstating the case. They presented the wrist technique as something that feels effective, while acknowledging they could not confirm whether the cooling is physiological or a placebo response.
That honesty is itself useful. A low-risk technique that feels good and harms no one is worth trying — especially when the alternative is simply tolerating serious heat discomfort. In a summer where the Clapson household owned five thermometers simultaneously to monitor their children's temperature, every additional tool in the toolkit matters.
"Put something cold on your wrists because the blood vessels are much closer to the skin and then you're almost cooling yourself on the inside."

Parents fill a hot water bottle partially with water — not to the top, since water expands when frozen — and freeze it, then place the cold bottle in the child's bed before sleep. It's a simple, reusable way to pre-cool a mattress on hot nights.
Covering a pram or pushchair with a thick blanket is strongly advised against — it blocks airflow and causes the temperature inside to rise dangerously. The instinct to shade a baby this way can actually make the heat far worse.
Getting children to drink plain water can be very difficult. Adding a small amount of squash to make it more appealing is suggested — drinking something flavoured is far better than drinking nothing at all when it's hot.
