Study finds heat pain perception decreases with age

A. Experimental setup and conditions (created with BioRender.com); B. Correlation between age and pain thresholds; Significant difference in heat threshold; Pain ratings of heat stimuli across younger and older groups (**p < 0.01, ***p < 0.001); C. Significant difference in pain discriminability at various levels of heat stimuli; Correlations between pain discriminability and pain threshold; Correlations between age and discriminability of heat stimulation (**p < 0.01).
