Sobhan, who created man, amended in any manner whatever knee ... And asked us to reflect on great character and great workmanship, he said: (they see not in yourselves). God
has created a very small part of the brain called the hypothalamus and
thalamus that down with the size of that part be his finger but the
basic organization of the human body temperature (althermostat) and
basic work to do that under mulch is that the internal body temperature
of 37.5 degrees Celsius welatkl a proposal from 36.6 degrees Celsius in
Badi where controls that part of the thermal power of the muscles of the
body, including the heart and exits the body through the skin and lungs
often ... And that means administered by this system are heart and what correlate of blood vessels throughout the body.
In winter the greatest burden on the heart muscle:
Where
cardiovascular bear more burden to thermal changes in the human body,
scientific studies have shown that in periods of winter (outside
temperature below 8 ° c) increase in cardiac mortality significantly
compared to other times in the winter. Volume
18-Issue 5-p S70, Epidemiology and least ° c (within the body and is not
beyond) scientifically proven that man had escaped 13 ° c and for
seven-year-old Swedish girl found near drowning.

human body is external temperature below 35 ° c and starts to adapt to
the constriction of blood vessels in the skin and shivering cold
(clenching muscles almtkerrltolid heat) to maintain the internal body
temperature that enzymes and proteins your body through their
persistence. And even worse if cold weather with
rain as the cold water loses heat from the human body better b 25 times
of cold air, for example, the human body cannot swim in water
temperature 10 ° c because it leads to death in 60 minutes if you swam
in water temperature (zero Celsius) it died within 15 minutes and it
explains the rapid death of the majority of the famous ship (Titanic),
where the majority of the passengers swam in water temperature-two under
Zero Celsius the quick mortality within 15 minutes. The majority could not be saved.
If the cold is accompanied by winds, the impact of the cold the most. For example, if the temperature is 0 ° c and wind speed of 45 km per hour, the body temperature is 10 degrees below zero.
Changes that occur in the human heart when exposed to cold:
When the body is exposed to temperatures below temperature assume simple temperature (32-35 ° c) vital changes:
1. increase the heartbeat
2. high pressure 18-20 mm of mercury
3. peripheral arterial contract to prevent the heat
4. increase consumption of oxygen
5. rapid breathing
In normal human is not a problem. But
the problem is that most of the problems of cold in the winter are the
elderly who are of course vulnerable to cardiovascular diseases than
others. It has a narrowing in the arteries of the
heart may cause extra effort is the so-called angina (out of date) or
increases it causes him a heart attack. And what
we see is heart clots in elderly when they remove snow in front of their
homes to skate they mistrust cardiovascular diseases that were not
originally infected. If increased sharply cooler
body to less than 20 ° c all these changes turn to fully reversible
hypotension and slowing heartbeat and breathing slow down of the body
for the rest of the energy is in the final stages leading up to the
death of the patient. And strange behaviour occurs for these patients before they died of cold is they they take off their clothes!! There
is no scientific explanation for the phenomenon known as the muscles
that were blood vessels contracta suffer fatigue and then expanding the
blood vessels in the skin which makes the patient feel the heat and
throws his clothes add to the confusion.
Common errors in winter:
And errors in which many people in winter:
1. sleep in a room or tent and firewood for ignition and safety of cold and fall into the danger of carbon monoxide poisoning
2. not listening to weather forecasts and warnings and is very important to avoid going out in the cold waves
3. stay away from drinking liquids in winter with cold weather causes frequent urination and dehydration.
4.
the most serious types of sleep is sleep without heating means for your
body, when shepherds in the desert or displaced from their homes
because of mental illness or older in age, children sleep in open
places.
Abstract:
You
must be attentive to our fathers and our mothers and those who have
heart disease from very cold and its confusing and place-oriented
sitting and eating and drinking which gives them the energy required
without adversely affecting the diseases suffered from physical effort,
whatever the cause, especially in winter.
