What else can I help you with?
What is the heat escape lessening position h.e.l.p designed to prevent?
The loss of body heat when in the water
How does the thickness of loft insulation affect heat loss?
the thicker the insulation is then there will be less heat loss. The material also affects heat loss
Does temperature affect heat loss in water?
Yes, it does.
What factors affect the loss of heat from a liquid?
true
What is the fastest method of body heat loss?
In high temperatures there are several methods of body heat loss. One is metabolic heat loss, which is where the metabolism of the body produces heat which is increased in higher temperatures, this in turn produces heat loss. There is heat exchange which is where body heat is lost when making contact with a cooler object. Also conductive heat exchange allows the body to lose heat as coming cool, like water or air, move around the person. The body also uses radiant heat exchange which is where the blood is sent to the superficial arteries and veins to let off heat. Finally there is evaporative heat loss which is of course when a person sweats and as that sweat evaporates it takes body heat with it, thus in turn cooling the body down.
What adaptations do marine mammals have in order to deal with the cold temperature of the water?
Marine mammals have adaptations such as a thick layer of blubber for insulation, a counter-current heat exchange system to retain body heat, and a low surface area to volume ratio to minimize heat loss. They also have specialized blood circulation that helps in retaining heat in the body.
What is the balance between the heat loss and the heat produced by the body?
the right side
How colours affect heat loss?
blue blue blue
What is the heat escape lessening designed to prevent?
the loss of body heat when in the water
Is vasodilation a defense against heat loss?
Vasodilation actually facilitates heat loss, by bringing blood closer to the surface of the body, where the heat can more readily move from the body to the surrounding environment. The body employs vasoconstriction to retain body heat, for the opposite reason. Thus even though vasoconstriction can cause peripheral coldness and pallor, it's only because the body is conserving its heat in an attempt to prevent the core body temperature from dropping.
What is the heat escape lessening posture designed to prevent?
the loss of body heat when in the water
What is the heat lessening posture H.E.L.P. designed to prevent?
