Heat is back in full swing earlier than usual ！ Take precautions to prevent heat stroke ！.

On June 16, the heat index （ WBGT ） in Nara City recorded 31.1, which is the most "dangerous （ 31 or more ）" to pay attention to on the "Guidelines for Daily Life" in the heat. This is the earliest in the past 10 years （ 2016 ～ 2025 ） including 2024, the hottest summer in recorded history.

The real heat arrives earlier than usual, and the JMA's 3-month （ 7 ～ September ） forecast is also predicting another year of above-normal average temperatures.

If you are an elderly person, a child, or have such a person in your family, in addition to replenishing your fluids ・ and salt, we have designated approximately 130 facilities in the city as cool oases, so please make active use of them to get through this summer ！ <

*Heat index （ WBGT ） … Calculated based on temperature, solar radiation ・ radiation （ surrounding thermal environment ） and humidity.

1 ． To prevent heat stroke
the number of deaths due to heat stroke exceeds 1,000 per year in some years, far exceeding the number of deaths due to natural disasters such as earthquakes and typhoons.

The number of days with a maximum temperature exceeding 30°C is increasing every year, and the percentage of extremely hot days （ with a maximum temperature of 35°C or higher ） is increasing. This means that heat stroke can strike anyone, but the elderly and children are especially at risk and should be aware of it.

2 ． Why are the risk of heat stroke higher ？
The elderly are at higher risk for heat stroke for the following reasons.

Less sensitivity to changes in the body, such as heat and thirst

Less fluid in the body

Sweating ・ Decreased skin blood flow and slowed increase （ Reduced ability to regulate body temperature ）

resulting in less or delayed behavioral thermoregulation （ and heat avoidance behaviors ） such as adjusting body temperature with clothing or turning on air conditioning

Children are at higher risk for heat stroke for the following reasons children are more likely to suffer from heat stroke because their bodies are more developed
their bodies are still developing, so the body's ability to regulate temperature （ and sweat ） is not yet developed

they are shorter and thus closer to the hotter surface

they cannot verbalize and express their physical discomfort or changes
Children may have a very high deep body temperature due to their small size, which makes them susceptible to outside temperatures. If the face is red and sweating profusely, let the child rest in a cool place.

Also, children are most likely to develop the disease during sports （ 2024-6. Children ＝ 1 month old ～ under 18 years ）.

The back seat of a car with the engine off and shut off can exceed 50°C. Never leave a child in a car, even for a short time.

3 ． Heat stroke prevention
1. Prevent dehydration
Hydrate frequently and replenish salt when sweating.

The daily water requirement is 2.5 liters, and approximately 1.0 liter of water is supplied from food, excluding beverages, so eat well.

For hydration, sports drinks and other drinks are consumed （ Oral rehydration solution is consumed by people with heat stroke ）.

2. 2. Reduce the rise in body temperature
Cool clothing and parasols ・ Use hats

Heat acclimatization （ Moderate exercise from the beginning of the hot season to ）

Take it easy when it is hot or you are not feeling well

As a guide to heat stroke prevention, heat stroke incidence increases rapidly when the heat index （ WBGT ） exceeds 28. When the predicted value reaches 33, a heat stroke advisory is issued, and when the predicted value reaches 35, a special heat stroke advisory is issued, and countermeasures are recommended accordingly.

Please refer to the Ministry of the Environment's website for information on heat stroke prevention.

4 ． About Chikkiri Oasis
More than half of emergency cases of heat stroke are caused by the elderly.

The most common situation when transported is "in the living room" （ at home ・ in one's own room, etc. ） followed by "while walking" （ while out walking, shopping or visiting the hospital ）.

Factors contributing to heat stroke among the elderly （ 2024 ）
Overwhelmingly more than in situations where heat stroke is likely to occur, such as farming and sports

Proper ！

To help protect you from the intense heat, approximately 130 facilities in the city have been designated as "cool oases" and are open to the public as spaces where you can stop by and cool off.

In addition to the cooperation of post offices and pharmacies ・ as in the previous fiscal year, private companies have been added this year, allowing visitors to use the facilities just to cool off ・ and take a rest even if they have no business there.


Shikamaro-kun's "banners" and posters are landmarks.
Examples of installation at stores of private companies

Child caregivers can use the Shikamaro-bon for shopping, picking up children from school, or taking children out of school, while the elderly can use it for shopping, going out （ taking a walk, or visiting the hospital ） for a short rest. Please use it to take a rest.

We have received comments from users such as "It was nice to have a cool place to rest" and "It was good to have a place to sit and rest".

We are also looking for private companies and various organizations that would like to cooperate in the installation of the cool oasis, so please contact us （ Installation is subject to standards based on the Climate Change Adaptation Act and other laws ） .
