Heat

Excessive heat contributed to 1,670 deaths nationwide last year, according to federal data — the highest rate in at least two decades. An increase in drug use and homelessness, along with hotter temperatures, were among the reasons.

State and federal agencies are scrambling to find measures to combat rising heat deaths and injuries of people who work in triple-digit temperatures.

Where trees are growing — and who has access to their shade — affects health and well-being, especially in Florida, one of the hottest states in the country.

Amid multiple excessive heat warnings, the district is emphasizing heat protocols for athletes and students who do activities outside.

The facility received chillers over the weekend to help cool down inpatient units. Patients in long- and short-term care have been assigned to other rooms. Non-urgent procedures were postponed.

Death certificates don’t always reflect the role that extreme heat played in ending a life, even when it seems obvious it was a factor. That imprecision harms efforts to better protect people from extreme heat.

Recognizing the symptoms can prevent worsening conditions as excessive heat stands as the leading contributor to weather-related fatalities, according to NOAA.

The study assigned subjects to one of two rooms: 68 degrees or a sweat-inducing 86 degrees. They played a computer game that can bring out the worst in human nature. What are the real-world lessons?
