Japan research links tongue strength to facial aging and frailty

A study by Okayama University found that low tongue pressure is associated with poorer nutrition, higher rates of sarcopenia and facial sagging. The research showed that women’s tongue strength begins to decline from age 18, reaching levels similar to those of seniors. Modern habits—soft diets, prolonged smartphone use causing forward head posture, and chronic mouth‑breathing from allergies—contribute to a condition called “tongue drop,” which weakens the muscles that support the palate and facial contour.

Dental hygienist Yumiho Ishino recommends simple exercises to strengthen the tongue and surrounding oral muscles. Chewing gum for ten minutes before meals and performing tongue‑circling or pressing drills have been shown to improve facial line angles and increase jaw bone density. These oral‑frailty symptoms—choking, food spillage, slurred speech—can lead to reduced food intake, nutritional deficits, muscle loss and social isolation, underscoring the need for early detection and routine oral‑muscle training.

The combined guidance highlights that maintaining tongue strength may help prevent oral frailty, support overall health, and mitigate age‑related facial changes.
