What (if any) is the health benefit from working out in heat vs. cold?

I can not believe no one has answered this as yet.  I read some books on loosing weight and one of them stressed keeping your system cool. I can not remember why since all I needed was to do it at the time.  You are trying to change the ratio of muscle to fat and doing exercise slowly helped, I remember this author thought.  Drink lots of cold water.

the benefits of sauna is that it gets rid of fats in ur body using the heat it generate,nd it makes u thiner and lighter, its one way to help people lose weight but for sure with a good programmed diet.sauna can be intered every day,preferable 3 days a week 30 to 45 minutes each and to have the best result and to have a better stretched skine, u should jump in a Very cold water pool directly fter u go out of the sauna.coz ur skin and body will be in a hight temprature, and then u go jump in a cold water ur skin will be stretched and healtheir have fun bye

Before and after is fine if you are doing just normal static stretching (holding it in one place).  If you are doing more advanced stretching you need to be properly warmed up first.\n\nStretching "cold" muscles will not lead to long term gains in flexibility, rather it will lend temporary flexibility in the muscles which may help prevent some injuries.

One difference we have in comparison with a lot of other mammals is that we have a lot of sweat glands in our skin. They help to prevent our bodies from overheating, especially during exercise. As sweat cooling your body works best if the air on your skin can move easily (and especially if a breeze of air is blowing) I would guess that fur/hair would decrease the efficiency of this cooling system a lot. As humans are supposed to have evolved in warm areas of Afrika, protection from cold was not an issue for keeping hair. And protection from sunburn - as a upright walking species we kept our hair on the place where sunburn would be most of a problem. \nThat's my guess, so that may not be true, but I read not too long ago that sweating allows humans to exercise much longer without overheating than a lot of animals (and so hunt an animal to its heat exhaustion, despite if may be able to run faster), if you look up these studies you may find more.\nPS. I found at least one source for that theory, I added it below

I know you want to avoid icy cold drinks when its hot, because your body may reject them.  Especially if you are working out or dehydrated, its better to drink room temperature or only slightly cool water.  But hot drinks dont sound that good for you either.

Not necessarily evaporation of sweat.  It is the removal of ambient heat being put off by your body.  On a very cold, but not windy day, you can stand outside without a shirt on and feel somewhat comfortable.  The heat of your body is radiating into the air around you and staying there.  If the wind is blowing, then it is taking heat out of your body faster and making you feel cold.

Contrary to what is believed, alcohol may make you feel warmer but it actually lowers the temperature of the body. When alcohol enters the blood, it causes the blood vessels to widen.  More blood flows to the skin's surface.  The drinker's body temperature drops as the increased blood flow to the surface allows body heat to escape.  People who drink alcohol in cold weather to get warm actually accomplish the opposite.\n\nThough carbohydrates are known to be the best source of heat and energy, all what you eat are actually contributing in producing your body heat. So eat a well balanced diet and wear sufficient clothing to combat coldness while you go out. Instead of bringing a flask of scotch on route why not bring a flask of hot drinks instead?☺

i think u must try for "chyanprash" An Indian Ayurvedic product very effective to prevent u from getting cold. And the physical exercise whenever u feel cold. It'll definitely help u as u see when u do some physical work u get sweats.

It certainly can, but how is slightly unclear, exposure to cold causes your blood vessels and capillaries to constrict(shrink) to prevent heat loss which in turn increases the blood volume in rest of body and possibly making heart work harder and thereby triggering angina.

jog a litle bit to warm up your muscles,them stretch.Don't stretch cold muscles

Drinking lukewarm water does not burn more calories...as others have said the colder the water the more energy (calories) your body uses to raise the water's temp so that it can be absorbed into your blood.\n\nDisregard the comment that was posted by someone saying slow jogging burns more calories.  This is a myth, you should pace yourself to jog as fast as you can for the time you have allotted for exercise, this will maximize your caloric burn.

it doesn't matter the temperature, whether cold or warm it all gets boiled in your body. The best thing for you to do is have a proper diet, drink a ton of water and milk and go to the gym about 3-4 times a week for about an hour, this will make you lose your weight in no time

A recent study confirmed your theory.\n\nIt is particularly the case when the feet or hads are cold.\n\nOf course, like someone said, it is not the coldness alone which makes you ill, but, like you said, your "resistance" is somehow lowered (I think it is that the immune response is slower) and that makes you more vulnerable to any pathogen.

heat speeds up movement because molecules shrink and there is more room for movement. cold slows down molecule movement because they expand and there is less room for movement. It's basic physical science.

your breath is warm compared to cold temperatures

That is actually an interesting question.  Scientists have shown that shivering is actually a very effective means to move the body around, which in turn is a good way to generate some heat quickly.  Going for a run would do the same, but the brain sends a signal to shiver just to get your body heat up.  \n\nYou also may shiver when you are sick.  Fever is one of the body's defense mechanisms.  (It helps kill germs, although it is dangerous when it gets too high.)  So you run a fever, and one way to heat up is to send the word to shiver.\n\nGood luck!!

Hot or cold is relative to your body temperature. Something less will feel blah, cool, or cold depending on how much less. Vice versa for hot. The 'starting point' for hot or cold can be different for each person, or even for the same person, like if you just worked out, everything will seem a little warmer for a while.
