Heat Advisory Criteria and Health Guidelines Heat advisories are based on the perceived temperature, which reflects both temperature and humidity, rather than on actual maximum temperature alone. Therefore, an advisory may be issued even if the actual high is below 33 degrees Celsius, provided humidity is high.

The risk of heat-related illness can increase the day after a tropical night due to lack of sleep and reduced physical recovery, so the following guidelines should be observed.

• *[KMA Recommended Action Guidelines]**
• Refrain from outdoor activities: In severe heat warning areas, suspend or postpone outdoor activities and outdoor work, except for essential operations.
• Cope with the heat: Move to shade, a heat shelter, or an air-conditioned facility, and drink plenty of water.
• Check on vulnerable groups: Check on the well-being of elderly people living alone, those with chronic illnesses, and other family and neighbors.
• Respond to heat-related illness: Call 119 immediately if symptoms occur.
• Cope with tropical nights: Use air conditioning and fans, drink water before bed, and avoid caffeine and alcohol.
• Adjust schedules: If you did not get enough rest the night before, reduce the intensity of outdoor activities the following day.
