Let's be careful about heat stroke
Heat stroke tends to increase rapidly from time of passing of the rainy season to August in average year, but, at this time when tropical day with more than 30 degrees Celsius of highest temperature in the daytime continues, attention is necessary for heat stroke because it is easy to be.
It is heat stroke that may be life-threatening when symptom gets worse, but can prevent by appropriate prophylaxis. Let's perform heat stroke measures well.
Preventive point of heat stroke
Supply of 1 moisture, salt "will take moisture even if we do not feel drought"
●Let's take moisture diligently
⇒When we felt drought, internal moisture has been already short. Let's take moisture diligently even if we do not feel drought.
●When we sweated a lot, let's take moderate salt
⇒Salinity of body falls down when we drink only water and tea as 2-3 grams of salt per 1 liter is included in sweat when we broke a lot of sweats and may cause muscle cramp.
We take appropriate quantities of salt including sports drinks, and let's do.
If it is sports drinks containing ion drink and 40-80 milligrams of sodium (in 100 ml), we can take appropriate quantities of salt with moisture.
●Quantity to drink in once will make around one cup of glass (150-200 ml)
⇒We subdivide appropriate amount, and let's drink without drinking lot at a time.
●Even if we are in the room where air-conditioner worked for and do not sweat, moisture of body is lost
⇒We will supply moisture without feeling relieved when we turn on air-conditioner.
In addition, let's mind family.
●Moisture is not enough only by taking alcoholic beverage including beer
⇒As alcoholic beverage raises diuretic effect, moisture might be lost more and more by body.
Let's supply not only alcohol but also moisture properly.
"Let's perform attention to 2 clothes to clothes which can miss heat outside"
●Let's keep air permeable good clothes in mind
⇒As size of the neck is part with much release of heat, it will prevent you from tightening.
●Let's devise with imminent thing to prevent rise in temperature
⇒Used ice pack and bamboo blind, round fan, and squeezed around neck coolly; get wet, and wind up towel, and let's devise.
●We absorb sweat, and let's wear clothes of air permeable good material
⇒Material chooses cotton or hemp, and color will choose whitish color not black, too.
●Let's avoid direct rays of the sun when going out
⇒Temperature under outdoor hot weather becomes higher than temperature of weather forecast. When we appear outdoors, we put on hat and will put up our sunshade.
"28 degrees will be used as an indication of temperature of room" temperature control of three rooms
●Let's put thermometer which we are easy to look at in room
⇒We put thermometer and will check diligently.
●We prevent direct rays of the sun with bamboo blind and curtain, and let's make ventilation better
⇒Because effect of air-conditioner may worsen by solar light to enter at window even if we use air-conditioner, let's cut off direct rays of the sun with curtains.
●Let's use electric fan and air-conditioner
⇒On temperature and humid day, impossible power saving will use electric fan and air-conditioner moderately without doing.
●It will prevent window from being closed up
⇒Let's spend time in good room of ventilation without shutting up window and door.
●Let's sprinkle in the evening
⇒Temperature falls to take heat around the surface of the earth. It will be good to perform using the second use water such as rainwater or remainder water of bath.
Health care on about 4th "will be sweaty by moderate exercise"
●It is important to usually sweat
⇒We take a lot of moisture and raise diuretic effect and can regulate temperature by writing sweat more and more.
●Let's exercise routinely
⇒We exercise, and let's increase muscles to increase internal fluid volumes. It is important to supply with moisture, salt well before exercising.
●Poor physical condition is to watch out
⇒Let's be careful to become easy to suffer from heat stroke at the time of lack of sleep and hangover, poor physical condition including slight cold.
●WBGT level will perform reference, too
⇒WBGT level is index of heat calculated by temperature, humidity, radiation (emission) heat,
The standard value depending on the degree of exercise and work is determined.
Observation level and expected numbers are published in homepage (heat stroke prevention information site) of Ministry of the Environment.
Heat stroke that Part 5 is working on occurs frequently
●When we play sports indoors, let's supply with ventilation and moisture, salt
⇒We open window and door indoors, and let's make ventilation better. In addition, let's supply moisture, salt lost by exercise.
●There is big difference in heat tolerance by individual.
⇒When when is tired, need more sleep, such as a cold when is ill-conditioned, let's stop exercising forcibly.
Symptom of heat stroke
|Dizziness, muscular pain, mass sweat※|
Medium grade symptom
|Headache, feeling unpleasantness, nausea, vomiting, lassitude, despondency|
|Motor deficit, hyperthermy of disturbance of consciousness, convulsions, hands and feet|
※ As there is not sweat if heat stroke becomes severe and becomes dry skin, what we do not judge only from sweat is important
Emergency measure before ambulance coming
●Refuge to cool environment
⇒Let's rest quietly in bed at good place of ventilation in the room where air-conditioner worked for or the shade.
●Stripping and cooling
⇒Let's do invention to lower temperature by cooling with ice pack sending wind to bathe in water which takes off clothes, and misses heat.
●We supply with moisture, salt
⇒Let's refrain from impossible intakes to be in danger of aspiration on vomiting.
Alcohol, caffeine add to volume of urine, and let's wait as dewatering may advance.
Oral supplementary water liquid (thing which dissolved salt and glucose in water) and sports drinks which we can supply with salt lost for sweat are most suitable.
It becomes indication of conveyance to medical institution not to be able to drink water by oneself.
Let's cope early before not becoming seriously ill.
Let's be careful about such points
Let's mind change of everyday physical condition
Custom for physical condition and heat on the day becomes factor to cause heat stroke, too. We will usually mind change of oneself and neighboring physical condition.
Elderly person and child, person with a disability, child with a disability require attention in particular
●Of patients with heat stroke half is quite elderly person 65 years or older.
⇒As elderly person has decreased sensory function for heat and water deficit, and adjustment function decreases because we correspond to heat, attention is necessary.
●Consideration to one having difficult that we appeal for poor physical condition including child is necessary.
⇒As for the child, adjustment function of temperature has not developed enough yet, and it is said that it is difficult to appeal for poor physical condition.
It is important to mind small change of child.
When when we were at a loss, we were in trouble
●Emergency care information, consultation dial (telephone consultation)
#When 7119 is not connected; ... 045-222-7119 (cell-phone correspondence)
●We want to look for emergency care engine
