With temperatures soaring across the UK, a TV doctor has reminded Brits of the NHS '6-8 teaspoon' rule for sunscreen application to prevent long-term skin damage. Dr Sara Kayat, appearing on ITV's This Morning, stressed that most people underapply sunscreen, increasing the risk of sunburn and skin cancer.
Dr Kayat explained that for an average body, six to eight teaspoons of sunscreen are needed. As a simplified measure, she suggested using two fingers' worth of product per teaspoon, applying one teaspoon to the face and neck, one to each arm, one to each leg, one to the torso, and one to the back. She emphasised reapplying every two hours, or sooner if swimming, sweating, or rubbing.
The NHS advises choosing sunscreen with at least SPF 30 and 4-star UVA protection, and checking expiry dates. Sunscreen alone is insufficient; wearing appropriate clothing and seeking shade during peak hours is also recommended. The NHS notes that most people do not apply enough, and applying too thinly reduces protection.
To ensure adequate coverage, sunscreen should be applied 30 minutes before going outside and again just before exposure. Reapplication every two hours is crucial, as the sun can dry it off the skin. Even water-resistant sunscreen must be reapplied after swimming, towelling, or sweating.
