Effects of Aging on Pain Tolerance: A Comparative Study of Heat Pain Thresholds and Tonic Heat and Cold Stimuli

These results underscore the importance of stimulation characteristics in evaluating pain tolerance across the lifespan. The study highlights an underexplored heat-specific vulnerability in older adults, offering insights for refining experimental pain models, improving age-sensitive assessments, and encouraging further research into physiological mechanisms underlying altered pain processing in aging.
