The 3 Natural Ways Body Against the Cold

Have you ever seen a movie that the characters are trying to survive in life in extremely cold weather . Yes , even if it seems trivial cold weather can also be harmful to health , even causing death . Especially when you are in a place that is wet and cold .Even so , the body has its own way to react and adjust to the cold. Just as when faced with hot weather , the body also has natural ways to cope with the cold that reaches it . In order to survive in cold weather , the body must maintain a warm temperature inside .Here are some natural ways that made ​​the body as reported by Live Science ( 02 / 01 ) .

1 . Reduce energy expenditure 
The body will naturally seek a source of energy to burn to keep warm . In addition , the body also will allocate energy with extreme caution to all parts of the body . During this process the body will reduce some of the muscle contraction and reallocate the amount of carbohydrate used . When the temperature decreases and becomes increasingly cold nervous system will work more slowly and impulses that drive the muscles will be slower .The body will use more carbohydrates to produce lactic acid . Lactic acid is combined with a slow nervous system will make the body work more slowly and retain heat in the body .

2 . Blood flow is reduced
Cold weather causes blood vessels to constrict and blood flow becomes increasingly slow . Blood vessels are the first to shrink the skin around the fingers , hands , and feet . That is why these areas of the body feels cold faster than others . How this is done to limit the amount of body heat out , and keep the heat stays inside .The more heat that is in the body , the higher the chances of the body to survive . But it is also risky for people with hypertension and heart disease . That shrinks blood vessels will cause the blood pressure rise and affect how the blood is received by the heart . It also makes the heart work harder than normal .

3 . Began to shiver
 To keep the temperature remains warm , the body will try to produce heat from the muscles and by allowing moving organs , which we call shivering . Although this method uses more energy and is not efficient enough to generate heat , but the researchers explained that the new method is carried out of the body when the skin temperature on cold start .Actually our body is equipped with a natural mechanism for survival . It is very important when humans must deal with the changing weather and very bad , either hot or cold . But sometimes in extreme cases , the body will not be able to maintain the heat in him and can not produce heat . When this happens , the body will experience problems that can even be life threatening such as hypothermia.
