Reply to comment by SirDuke6 in ELI5: Why does putting one foot out from under the blankets bring so much relief of heat while laying in bed? by SirDuke6
Your blood makes a complete circulation three times every minute. This includes your extremities. I have always attributed the instant cool feeling to this fact coupled with the blood vessels close to the surface. It’s also the reason you can cool down really quickly by putting you hands in cold water in the summer time.
