How it works, and why it matters here

The towel holds water in its structure and cools by evaporation as that water leaves. Wet it, wring it, snap it out and it drops below the surrounding air temperature — no refrigeration, no chemicals, nothing to recharge. When it warms up, wet it again.

Worth saying plainly: evaporative cooling works less well the more humid the air is, and Singapore is humid. You will not get the dramatic effect the packaging implies on a still, muggy afternoon. What you will get is a usable drop in temperature at the neck, which is where it counts, and a noticeable difference in a breeze or under a fan.

Why the neck

Major blood vessels run close to the surface there, so cooling the neck cools what is circulating rather than just the skin. It is the same reason people put a cold drink against the back of the neck rather than the forearm.

Using it on site

• Soak, wring out the excess, then snap it sharply to activate.
• Re-wet whenever it stops feeling cool — there is no limit to how often.
• Rinse it out and dry it at the end of the day rather than leaving it balled up in a bag.

Not a substitute for drinking water and taking breaks in the shade. Heat stress on site is a real hazard and a towel does not fix it.
