The extremities get cold faster, because they have a larger area for their supply of blood. Because of the body's protective mechanisms, the chest (heart) and head (brain) will be given priority blood flow.
However, places with high blood flow for their area (groin, armpits, neck) can lose more heat without these protective responses, because the large blood vessels are nearer the skin surface.
In cold water, it has been shown that if the head is submerged that the body's temperature drops quicker. The theory is that certain parts of the head have a type of blood vessel which directly affects the heating and cooling of the body. These same vessels are found in the palms and the soles of the feet.

How can you make air colder?
There is nothing which 'makes' air cold as such - heat spreads itself around the space available, moving to the colder parts until the air is all the same temperature. Heat energy always balances itself out. Air gives up heat when in contact with something colder. This could likely be very cold land or sea ice areas at the poles, or cold areas of the oceans. Air also gets colder with increasing altitude, because it loses heat out to space by radiation, whereas near the ground in warm areas of the earth it picks up heat from the ground. In general thermodynamic laws say that a body will only lose heat to a colder body. Remember "heat won't flow from the cooler to the hotter".
Why does Hot water extinguishes fire more effectively than cold water?
Hot Water extinguishes more effectively than cold water as it has a higher specific heat capacity than cold water.
Why is the solubility of benzoic acid poor in cold water?
temperature affects the solubility of a substance..benzoic is poor in cold water because it is only slightly soluble in water..in order for it to reach the point of saturation, heat must be applied..heat acts as a catalyst..
How does water make you cooler?
when we sweat , water use the body heat for vaporisation as water to vapour formation is a endothermic reaction. so the heat required for this reaction in case of sweat evaporation is body heat. as our body lose heat, our body becomes cool.
How does high heat capacity effect large bodies of water?
Bodies of water affect climate in other ways., too. Water takes longer to heat or cool than land. As the air and land heat up in summer the water remains cooler.How do body's of water effect the tempeture?
Why do you feel cold when you drink cold water?
Our body temperature is high then cold water so when it comes in contact with our body energy in the form of heat is transferred from body to water so it decreases our body temperature and we feel cold.
How fast does the body loose heat in cold water?

Describe how the body can loose heat in conduction convection and radiation?
you are swimming in ice cold water and losing heat. How does heat leave your body?
How do you cool your body?
drink water in heat and put a coat on in the cold
If you are cold what mains areas of your body should you cover up to help keep body heat in?
Nothing freeze to death
Why sand feels hot in summer while the water feels cold?
sand get quickly heat and got cold where as water is not it takes time to heat and cold that's why people living in coastal areas feel cold during day time .
Why the cheeks of people living in cold areas very red?
The persons body heat from exiting the pores of the body turn red.
Why do you get cold when you get in a swimming pool?
You feel cold after being in water because you are wet. Your body begins to evaporate the water so that you can become dry again. Where does the energy ( heat ) to evaporate all that water come from? That's right, your body.
How fast does the body lose heat in cold water?
25 times faster
Why is your body cold when you hair is wet?
your body is cold because the air around you is colder than the water in a shower or bath unless you are taking a hot bath.---------------------AND when water evaporates it absorbs heat, taking that heat away from you.
How is heat being transfered when you place your finger in the cold beaker why?
If the beaker has a cold water, or something else cold, in it than the heat that is in our finger will run out of you finger into the cold water. This leaves your finger 'empty' of heat, giving you the sensation of being cold. You need to remember that only heat moves. When you are cold you wear a jumper that keeps the heat in your body, not keep the cool out.
Why do we feel cold after bathing?
When we come out of water, our body is covered with water droplets. As the water droplets evaporate, heat is removed from our body as we know that evaporation causes coling thus We fell cold.....
