CHRISTUS Health urges heat safety as summer temperatures rise

With summer temperatures climbing across the region, CHRISTUS Health urges residents to take precautions against heat-related illnesses, including heat exhaustion and heat stroke.

Nationally, more than 1,300 people die from heat-related illnesses each year in the U.S. Men and older adults are especially vulnerable to extreme heat, with males accounting for 70% of heat-related deaths and more than half of fatalities occurring in people age 60 and older.

Signs of heat exhaustion include heavy sweating, weakness, dizziness, nausea and muscle cramps. Heat stroke symptoms are more severe and may involve confusion, rapid heartbeat, fainting or unconsciousness.

“A person with heat exhaustion may feel ill but is usually still alert and able to respond,” said Dr. Greggory Angier, trauma medical director at CHRISTUS St. Michael Health System. “Heat stroke is far more serious—it’s a medical emergency where the individual may be confused, unresponsive or unable to follow instructions, and requires immediate hospital care. If someone can still follow instructions and drink water, it’s likely not a heat stroke yet—but it’s still serious.”

Dehydration can escalate quickly in extreme heat. Early signs include dry mouth, dark urine and headaches, while more severe symptoms may include confusion, rapid breathing or fainting.

“The old rule of eight glasses of water a day is just a starting point,” he said.

Those most at risk of dehydration include children, seniors, individuals with chronic conditions like diabetes or heart disease and those on certain medications.

“Most heat-related illnesses are preventable,” Angier said. “Stay hydrated, wear light clothing, avoid peak heat hours and take frequent breaks if you must be outside.”
