Heat-Related Health Concerns in Southern California
Officials are raising concerns about the health effects of the intense humidity and heat currently experienced in Southern California. Heat-related illnesses are a significant concern in the region, as well as elsewhere, due to climate change and rising temperatures. Despite this, the public is still understanding the severity of these dangers.
Statistics on Heat-Related Deaths
A survey by The Times in 2021 reported 3,900 heat-related deaths in California over a decade. Challenges in providing aid to those affected by heat were highlighted, affecting many public agencies.
Increase in Emergency Visits
Public health authorities in Los Angeles County have noted a surge in emergency visits for heat-related illnesses during recent heatwaves. This is tracked through a heat-related illness and mortality dashboard managed by the county health department.
Impact of Humidity
This week, humidity is exacerbating the heat, making temperatures feel hotter. Climate scientist Daniel Swain emphasizes that the humidity levels are unprecedented for Southern California.
Experts indicate humidity hampers the body’s cooling processes. The moist air prevents sweat from evaporating efficiently, causing an increase in body temperature. Lower humidity reduces heat-related health risks.
Understanding Heat Stress
Dr. David Eisenman, from the David Geffen School of Medicine and Fielding UCLA School of Public Health, explains “Heat stress” as the total heat load required to maintain stable body temperature.
Our bodies function optimally when internal temperatures are around 98.6 degrees Fahrenheit. When external temperatures rise and humidity hinders sweat evaporation, the body must work harder to maintain this optimal temperature. Eisenman suggests “skin wetting” as a technique to cool the body.
Using a spray bottle to mist your skin or soaking clothing in cold water can help maintain lower body temperature.
Guidance from Los Angeles Department of Public Health
- Stay Hydrated: Drink water throughout the day, even when not thirsty.
- Outdoor Precautions: Avoid outdoor activities during peak heat, wear light clothing, hats, umbrella, and sunscreen.
- Home Cooling: Use air-conditioned spaces or cooling centers.
- Car Safety: Never leave children or pets in cars.
- Check on Vulnerable Groups: Monitor individuals at risk, such as older adults, sick individuals, and pets.
- Emergency Situations: Call 911 for signs such as confusion, high body temperature, dizziness, and nausea.
Advice Without Air Conditioning
- Take cool showers or baths.
- Minimize stovetop and oven usage.
- Visit air-conditioned spaces.
- Contact 211 for assistance finding a cool area.
Recognizing Heat Illness
Signs and treatment guidelines from The Times:
Heat Exhaustion
Symptoms: Body temperature over 104 degrees, lethargy, dizziness, headache, fainting, and profuse sweating.
Treatment: Follow heat syncope instructions, remove excess clothing, wrap a wet towel around the body, and call 911.
Heatstroke
Symptoms: Body temperature above 104 degrees, loss of consciousness, potential dry skin, and lack of sweat.
Treatment: Seek a cool location and call 911 immediately.
