God malaria exceeds the body's self-defense
The
direct impact of the first cold weather damage caused recently dropped
below normal body temperature, exceeding the threshold of the reflex
action of the body defend itself. This
phenomenon is particularly hypothermia seen in children and the
elderly, the heating conditions in the round of cold weather is not
guaranteed to be required.
May explain why the temperature of an impact on the body. The roadmap is as follows:
-
Cold temperatures cause vasoconstriction, increased blood pressure and
blood concentration (due to increased consistency of the blood). So,
can loosen the grip of plaque on artery walls, creating favorable
conditions for formation of blood clots, causing intravascular
obstruction.
Moreover,
while the tangible components of blood are increased due to the blood
concentration levels of protein C anticoagulant properties in serum does
not increase the risk of causing blood clots to form strong, especially
in the old.
-
In the coronary artery vasospasm due to the cold combined with the
ability to create thrombosis and myocardial oxygen demand increases will
lead to or aggravate the angina pectoris, myocardial infarction, even
when heart arteries clog completely.
The statistics show that about half of all deaths rise in winter is caused by coronary artery obstruction by a thrombus.
-
The mechanism is also considered to be the cause of cerebral stroke,
especially ischemic type that the main risk is high blood pressure and
high blood cholesterol (especially increased LDL.C - bad cholesterol ).
Those at high risk
Weather
impacts on all of us, but with the patient and the following subjects,
need special care in cold weather conditions, avoid Stroke:
-
Subjects are chronic diseases such as ischemic heart disease,
hypertension, atherosclerosis disease, chronic respiratory disease.
-
The subjects are other chronic diseases such as diabetes, thyroid
disease, rheumatoid disease, addictions (alcohol, tobacco ...),
psychiatric disease, asthma, respiratory distress, using the type of
narcotic drugs, psychotropic drugs ...
- The object economic conditions too tight, lonely.
- The elderly are cognitive disorders.
- The subjects susceptible to cold, mostly the elderly. Feeling cold change in each person because of age, physical condition because, due to psychological factors ...
The
elderly are more susceptible to cold weather because of the reduction
in basic metabolism, reducing perceived as cold and can be caused by
chronic diseases associated mentioned above.
Only
in particular on the effects of cold temperatures for the elderly, the
objects need to take good care of the round cold weather damage.
Elderly people should avoid maximum outdoors, especially when it's windy. Serve hot, warm wear. Be careful not to get cold, drafts when bathing.
When the cold weather should not exercise outdoors and should not dress style brakes when training.
For people with heart disease, respiratory, need to control their chronic diseases are.
The identification Stroke
Stroke
is a critical complication, so in addition to the management and
control diseases are, you also need to catch the warning signs of
stroke, to timely treatment. The rate of complications decreases if discovered disease duration shorter.
Here are the warning signs of cerebral stroke:
- Severe headache, sudden. This symptom in 50% of patients.
- Suddenly dizzy, tinnitus, dizziness. One leg was quite weak, not strong.
- Suddenly a hand grip for sure no objects, easy to fall spoons, chopsticks, bowl. Pick up items for a hard fall.
- Suddenly language disorders: speech, lisp, people do not understand what the patient says. This
symptom may occur in only a few minutes, but can also extend the day
before the serious events occurred: the patient is no longer able
spokesman.
- Suddenly the patient feels like a needle, is burning in the extremities hands, feet, above the half.
- Appearance of "empty space": occasional patient lost control of himself. Who said suddenly lost momentarily new level continues to be the story. To drop items on hand that do not know and then a few seconds later remembered and picked it up.
- The intellectual disorders: patient suddenly disoriented for a few minutes, a few hours. Transient forget, transient hearing loss, disorientation in space and time.
- Suddenly there appeared feels like flies ahead, lose sight entirely or in part, or within two seconds.
Time
appears the warning signs of stroke until this actually happens with
the expression or semi-comatose body dissatisfaction, may 1-2 hours or
1-2 days depending on each person.
Phase anticipate described above nature is crucial in either patient survival or prevent disastrous sequelae may occur. The prognosis is calculated every minute. The emergency management measures shall be carried out very soon, quickly and accurately. Therefore, families and patients themselves need to be aware of the warning signs.
