I was sweating. My parents said it was cold. Not the first time.
It's not them being fussy β their bodies have changed. Metabolic rate drops 10-15% with age β less heat generated. Muscle mass decreases (sarcopenia) β less heat production. Blood vessels lose elasticity β poorer circulation to extremities. Temperature perception changes.
Don't argue with them about whether it's hot or cold β their perception is real. Help them dress in layers. Make sure they stay hydrated. Watch for heat-related illness signs β they may not notice the heat themselves. Understanding that their body feels the world differently makes it easier to live with.
