What is Hypothermia?
On January 1, 2024, at around 4:10 PM, a major earthquake with a maximum intensity of 7 originated in the Noto region of Ishikawa Prefecture in Japan. Currently, many people are living in evacuation centers. In the Noto region, there is snowfall, and the temperatures are low. In addition to concerns about infectious diseases in communal living situations, another significant issue is hypothermia. Sitting or sleeping directly on the floor of gymnasiums, for instance, can lead to a loss of body heat. Living in low-temperature environments can also contribute to hypothermia.
Hypothermia refers to a condition where the core body temperature drops to 35°C or below. Core body temperature refers to the temperature inside the body, including the esophagus, rectum, and bladder.
Hypothermia is diagnosed based on the following conditions:
- Mild: 35°C to 32°C
- Moderate: 32°C to 28°C
- Severe: Below 28°C”
When one experiences hypothermia, symptoms such as decreased consciousness, impaired judgment, and reduced circulatory function can be observed. If it worsens, it can lead to a heart attack and even death. Therefore, underestimating a drop in body temperature can lead to irreversible consequences.
As January approaches with lower temperatures, it becomes necessary to take measures to prevent hypothermia. This is especially important during the cold seasons known as “Small Cold” and “Great Cold.” Addressing low body temperature requires measures related to room temperature and the surface one rests upon.
Prevention and Measures for Hypothermia
The time spent in the bedroom, assuming an 8-hour sleep schedule, accounts for approximately one-third of the day. Nighttime temperatures tend to be lower than during the day, with the coldest period occurring around 3 to 5 in the morning. Therefore, creating the right bedroom environment is crucial for preventing hypothermia. Below are some key preventive measures:
- Apply insulation material to windows.
- Use double curtains to prevent cold air from entering through windows.
- Lay tatami mats or carpets over the entire floor to insulate against the cold.
- Use a bed or similar elevated surface during sleep to avoid contact with cold flooring.
- During winter, using an air conditioner while sleeping can lead to dry or sore throats. To maintain a room temperature of at least 10°C, consider using an oil heater at bedtime.
- Use extra bedding and utilize warm materials, such as a fleece blanket.
- Position your head towards the north and use a folding screen or partition to prevent cold air from reaching the head area.
Furthermore, there are measures you can take on your own, including the following:
A. Exercise daily.
B. Pay attention to your clothing.
C. Be mindful of room temperature.
D. Sunbathe.
