Why you should never take a cold shower during a heatwave (opens original article in a new tab)

Cold showers during heatwaves may hinder the body's cooling mechanisms and pose health risks, while lukewarm water is recommended for effective temperature regulation and hygiene.

• Cold showers during heatwaves may prevent the body from cooling effectively by constricting blood vessels
• Cold water can trigger cold shock response, increasing blood pressure and risk for those with heart conditions
• Lukewarm water (26-27C) is more effective for cooling and cleaning than cold showers
• Sudden temperature changes can disrupt the body's natural heat regulation mechanisms
• Cold water is less effective at removing sebum and may cause skin issues
