Description
Saito Sakaguchi and colleagues report a 2026 study of touch sensitivity in identical twins, designed to separate inherited influences from health and lifestyle. The team studied 25 pairs of monozygotic twins, who share essentially the same genes. Touch thresholds were measured with gentle suction stimuli applied to the cheek, and the results were compared with questionnaire answers and objective measures of physical and mental state.
In 18 pairs the twins had similar thresholds, pointing to a genetic influence on how sensitive skin is to touch. In the seven pairs whose thresholds differed, the twin with reduced sensitivity tended to report more physical and mental complaints, such as fatigue and anxiety. The authors suggest that dulled touch may act as a marker of wider health strain shaped by lifestyle, and could one day guide preventive care.
