Physiology - Activity and Metabolic Rates

Heat production from the human body vs. activity. Reference table showing metabolic rates in W/m² and Met units for various activities, with mean human body surface area of 1.8 m².

Activity	Metabolic Rate (W/m²)	Metabolic Rate (Met)
Laying down	46	0.8
Sitting, relaxed	58	1
Standing, relaxed	70	1.2
Sitting activity (office work, school etc.)	70	1.2
Standing activity (shop, laboratory etc.)	93	1.6
Moving activity (house work, working at machines etc.)	116	2
Harder activity (hard work at machines, work shops etc.)	165	2.8
