New smart sex dolls encourage moderate physical activity among seniors. By designing features that require gentle physical interaction, these devices help users maintain basic motor skills while avoiding the risks of overexertion. Compared to the traditional torso sex doll, these new sex dolls' activity recommendations are tailored to the user's health status, providing safe and reliable exercise guidance. Many rehabilitation professionals are beginning to incorporate these new sex dolls into senior rehabilitation programs as a dual tool for gentle exercise and psychological motivation. This integrated approach has shown significant results, with user compliance increasing by over 50% compared to traditional rehabilitation training.
