Japan: Beat the Heat, Start Acclimating Now!
21 May
Summary
- Heat acclimation, or getting the body used to heat, is crucial for preventing heatstroke.
- Experts recommend gradual exercise and bathing to prepare the body for rising temperatures.
- May humidity can be deceptive; vigilance against heatstroke is advised even before summer.
Japan is experiencing 'summer days' with temperatures exceeding 25 degrees Celsius, prompting experts to highlight the critical need for heat acclimation. This gradual adaptation of the body to rising temperatures is key to preventing heatstroke. The process allows the body to better manage its internal temperature through improved sweating and blood flow, but it requires one to two weeks to be effective.
To aid in this acclimation, individuals are advised to engage in regular moderate exercise, such as walking or jogging, and to incorporate regular baths. Experts also stress the importance of hydration and maintaining a well-functioning autonomic nervous system through adequate sleep and routine. Dr. Hideki Taniguchi warns against complacency, noting that high humidity in May can lead to unnoticed dehydration, increasing heatstroke risks.
This proactive approach is essential as the body needs time to adjust. Starting heat acclimation before the peak of summer ensures better resilience against the heat. The Japan Weather Association suggests consistent physical activity, like cycling or strength training, several times a week to prepare for warmer conditions.
