ヒートショックについて The importance of house temperature and how it affects your health

*We’re writing in Japanese followed by English translation

おはようございます。イデコです。

どんどん寒くなってきていますがいかがお過ごしでしょうか?

本日もお家の話。今日は最近自分の家で廊下に出るときに気合を入れないといけないほど寒いので疲れてしまいます(笑)(*_*;

脱衣所では息子たちが『寒い寒い』と急いで脱いでお風呂場で少しあったかくて、風呂のお湯に足をチョンと入れて『熱い熱い』…大人は口にはしませんが同じようなものです(笑)

そこで主人といつも話しているのがこの暖かいところから寒すぎるところ、寒すぎるところから暖かいところは体に良くないよね…いつかヒートショック起こりそうよねぇ…(; ・`д・´)

今のところ脱衣所にストーブを置いてません。でも何か対策したい。ストーブを買ったり、電気代だったりまた光熱費とか増えるバイ…と家計簿を見直す日々…(;^ω^)

そこで、やはりイデコはみなさんに後悔してほしくないので少し勉強したことを書きます。

ヒートショックとは体の表面温度が急激に下がり、血圧が上下が激しくなり脈拍に変動が起こってしまうことだそうです。血圧に変動があると心臓に負担をかけてしまい脳卒中や心筋梗塞につながります…

交通事故で亡くなる人よりもヒートショックで亡くなる人の方が多いそうですよ(>_<)

外では事故にあわないようにと気を付けているのに、家を建てるときにそういったお家での事故の面で考えてはいませんでした。

どうやったら家中の温度があまり変わらないようになるかな?どうやったら部屋と部屋の温度差を少なくできるかな?と考えて解消できればお家の中での事故は少なくなって、老後も安心して快適に過ごせるのだろうなぁと感じる今日この頃です( *´艸`)

The importance of house temperature and how it affects your health


Good morning, this is Ideko. It has been getting colder. Hope all is well you and your family.

 Today, my story is about the shock from the temperature change in my house through my story. This phenomenon is called “heat shock” in Japan. Heat shock is a serious condition that is caused by sudden temperature change. Recently, I have been getting tired because it is so cold that I have to push myself when I get in the hallway from the living rooms or bed room. lol.

 

⋆⋆⋆⋆⋆⋆⋆⋆⋆⋆⋆⋆ About “Heat shock” written by Noriko ⋆⋆⋆⋆⋆⋆⋆⋆⋆⋆⋆⋆

Heat shock is the phenomenon where by people’s skin temperature suddenly goes down, it leads to a nosedive and sharp rise of blood pressure. This also leads to pulse change because of a sudden change in temperature. This can lead to a brain stroke and a heart attack. Japanese traditional building design makes people susceptible to heat shocks.

 In recent years, researchers started scientific studies on people who died while taking a bath in Japan. According to a study by the Tokyo Metropolitan Geriatric Hospital, in 2011, it is estimated that as many as 17,000 people suddenly died while taking a bath due to heat shocks in Japan. The death toll is about 4 times more than exceeding the death toll from traffic accidents (4611 people).

 Traditionally, people built well-ventilated houses (airy houses) for blowing off humidity and make the inside of the house cooler. This is because to stay comfortable in the house during the hot summer. It was a mainstream style in Japan, because previously people thought that “even if it is cold in the winter, it is better to cool down in the summer. Also if you are cold you can wear extra clothes and get warm from a fire stove.” This is why the thermal insulation performance of Japanese house’s is not good due to cold winter and hot and humid summer.

 In the old days, it used to be cold in the whole house, so heat shock was hard to occur. However, recently the performance of heating equipment has improved compared to the past, and the temperature of each room has risen. Due to the above reasons, the temperature difference has become bigger between warm living rooms and cold places where there is no heating equipment such as hallway and in the bathroom changing area.

◆◇◆ Process by which heat shock occurs ◆◇◆ 

1. From a warm living room to a cold bathroom changing area
(Blood vessel contraction due to cold → rise in blood pressure)

2. Get naked and get into a cold bathroom
(Vasoconstriction acceleration → further increase in blood pressure)

3. Get into a warm bathtub for a while
(Vasodilatation → gradually decrease blood pressure)

4. After taking a bath, get into a cold bathroom changing area again
(Vasoconstriction in cold → blood pressure increase)

 Now that we know the reason why Japanese style bathing style is unique. An improvement to the old-fashioned architectural style to accommodate Japanese climate and improvement of the house performance is necessary. Repeated and sudden cold and hot conditions causes the blood pressure to fluctuate and it places a heavy burden on the heart. For this reason, elderly people who die from heat shock are increasing every year.

 In Hokkaido, the coldest part of Japan, there is a severe and long winter, the heat insulation performance of the house is high and the central heating is popular. As a result, every room including the bathroom and toilet warms up. Consequently data on the number of cardiopulmonary arrests in the bathroom is 2nd lowest next to Okinawa prefecture.

 Since overseas, such health data is not calculated, foreigners might be surprised by these statistics. In order to eliminate the temperature difference between the rooms, it is necessary to enhance the airtightness and heat insulation of the building itself. However, most of the houses in Japan have the same level of insulation performance as “an old house” or less. Performance is difficult to fix. So, if you build a house in Japan from now on, please pay attention and consider airtightness and insulation performance.

(Back to Ideko’s story)

 In *²the bathroom changing area, my sons say “It’s cold, it’s cold” as they are freezing, while they rush to remove their clothes quickly. It is a little bit warmer in the bathroom than in the changing area. When they put their toes a little bit in the bath tub, they scream “It’s hot, it’s hot.”… Adults feel the same way, but do not show it like kids. lol

 Therefore, I always tell my husband. “It is not good for our health to move from a warm place to a very cold place and back to a warm place like a bathroom. I do not want to get heat shock…(; ・`д・´)

 For now, I don’t have a stove in the bathroom changing area. I think I should make a plan for something to prevent against the cold. Although, I have to buy a special stove for avoiding an electric shock incident. My utility bill will also more likely increase. Ouch… I have to review our household account book…(;^ω^)

 I always pay attention to avoiding car accidents, but if I knew I would have to be more worried about heat shocks because a higher percentage of people die compared to car accidents…(>_<)

 Things to think about ; How will the temperature in the house not change so much? How can I reduce the temperature difference from room to room? Thinking like this will reduce the likely hood of accidents as well as guarantee a peaceful retirement. ( *´艸`)

 For this reason, I am writing about my research because I don’t want you to regret it later. I’d like you to think about the temperature of the house once again before thinking about a house design.

 Please contact me about any concerns related to this topic ♬  Thank you.


*¹ 
Heat shock is likely to occur if you are over 60 years old and the temperature difference in your house is more than 20 degrees. Not only ourselves but also our parents and grandparents need to be extra cautions. Let’s prevent heat shock from cold weather by effectively incorporating heating and insulation renovation and paying attention to bathing methods.

*² In a Japanese bathroom, there is a separate area similar to a changing area where people remove their clothes.
