Extreme Heat

Heat-Related Safety Tips:

Extreme Heat often results in the highest number of annual deaths among all weather-related hazards. It is considered a period of high heat and humidity with temperatures above 90 degrees for at least two to three days. In extreme heat your body works extra hard to maintain a normal temperature, which can lead to death.

Follow these tips to stay cool:

  • Stay hydrated.
  • Wear loose, light-colored clothing, sunscreen, sunglasses, and a hat for protection.
  • Stay indoors and, if possible, in an air-conditioned place (shopping mall, library, etc.).
  • Check on neighbors who might be vulnerable to the heat, especially those without air conditioning. 
  • Never leave infants, children, elderly, or pets in a car. Temperatures inside a car can quickly skyrocket to deadly levels.
  • Keep pets indoors if possible. If kept outside, give them plenty of water and shade to rest in. 
  • If you work or play outside, take frequent breaks to hydrate and cool off in the shade. 
  • Symptoms of heat-related illness may include dizziness, fatigue, faintness, headaches, muscle cramps, and increased thirst. If you experience these symptoms, seek medical attention.

Heat-Related Illnesses:

Extreme heat is a grave and growing public health threat. Heat-related illnesses include heat cramps, heat exhaustion, and heat stroke. 

  • Heat cramps are muscle pains and spasms due to heavy activity; it usually involves the stomach muscles or the legs. Heat cramps are the least severe, although, they are often the first signal that the body is having trouble with the heat.
  • Heat exhaustion occurs when the body has difficulty cooling itself; dehydration is a main factor of heat exhaustion.
  • Heat stroke takes place when the body's temperature cannot be regulated. The body's temperature rises fast and is unable to cool itself.

People at Increased Risk for Heat-Related Illness:
  • Young children
  • Adults 65 and older
  • People with chronic disease or disability
  • Pregnant women
  • People who work outside
  • People without access to air conditioning

Although the very young and very old are most vulnerable to extreme heat, anyone who is outside is also at increased risk. The Fresno County Department of Public Health (FCDPH) monitors unusual spikes in emergency room visits through syndromic surveillance.

Extreme Heat and Youth Sports:

The California Department of Public Health (CDPH) recently released a comprehensive set of recommendations to keep school-age youth safe during extreme heat CDPH Extreme Heat Guidance for Schools (ca.gov). Those participating in outdoor sports, such as football are at particular risk, both because of the time of year when training and games are scheduled, as well as the heavy equipment worn. Fatalities in high school and college football players - PubMed (nih.gov) CDPH has recommendations for youth who are outside while participating in sports training or competitions including:
  • Stay in an air-conditioned indoor location as much as you can.
  • Assess your hydration and be aware of your individual hydration needs (urine color, body mass changes, thirst).
  • Schedule outdoor activities carefully.
  • Wear loose, lightweight, light-colored clothing and sunscreen. 
  • Pace yourself.
  • Take cool showers or baths to cool down. 
  • Check on other participants or teammates and have someone do the same for you. 

The State of California law AB 1653 Bill Text: CA AB1653 | 2023-2024 | Regular Session | Chaptered | LegiScan addresses extreme heat guidance for youth during sporting events. AB 1653 requires all schools with interscholastic athletic programs to have emergency action plans (EAPs) that include management of extreme heat emergencies. AB 1653 also directed the California Interscholastic Federation (CIF) to develop its own guidance for procedures and safety standards for the management of extreme heat illness. California Interscholastic Federation (cifstate.org)

CIF has also produced several documents to assist schools in preparing for emergencies including those related to extreme heat.  Emergency Action Plan Information - California Interscholastic Federation (cifstate.org) https://www.cifstate.org/sports-medicine/emergency_action_plan/EAP_1-pager.pdf

Consistent with AB 1653, both CIF and CDPH recommend schools use wetbulb globe temperatures (WBGT) to guide decisions about sports participation during extreme heat. The WetBulb Globe Temperature (WBGT) is a measure of the heat stress in direct sunlight, which takes into account: temperature, humidity, wind speed, sun angle and cloud cover (solar radiation). This differs from the heat index, which takes into consideration temperature and humidity and is calculated for shady areas. If schools do not have a WGBT tester, both CIF and CDPH recommend use of the National Weather Service (NWS) Heat Risk forecast for your community: NWS HeatRisk (noaa.gov).

  Heat-Risk-Graphic_1.png  

CDPH offers specific recommendations that FCDPH endorses when the NWS Heat Risk is “Major” or “Extreme”:

When the HeatRisk level is forecast to be "Extreme" (Magenta / Level 4):

  • Cancel all outdoor and unconditioned indoor activities A.
  • And, if feasible reschedule all outdoor activities and unconditioned indoor activities to a different day when the HeatRisk level is no longer "Extreme" (Magenta / Level 4) or "Major" (Red / Level 3).
  • Or move to alternative activities in an air-conditioned or cooled indoor environment.

When the HeatRisk level is forecast to be "Major" (Red / Level 3):

  • Cancel all outdoor and unconditioned indoor activities during the heat of the day (usually 10 a.m. to 5 p.m.).
  • And, if feasible reschedule all outdoor activities and unconditioned indoor activities to a cool time of the day if there is one (for example, very early morning).
  • Or reschedule all outdoor activities and unconditioned indoor activities to a different day when the Heat Risk level is no longer "Extreme" (Magenta / Level 4) or "Major" (Red / Level 3).
  • Or move to alternative activities in an air-conditioned or cooled indoor environment.

FCDPH communicates regularly with the Fresno County Superintendents of Schools and the CIF Central Section on a range of issues including these extreme heat recommendations. Decisions regarding school activities are made by individual school districts. To protect the health and safety of our youth, FCDPH strongly recommends that all school districts in Fresno County develop emergency action plans that conform to CIF guidelines and adopt the CDPH Health Guidance for Schools on Sports and Strenuous Activities During Extreme Heat.

 

Treatment of Exertional Heat Stroke:

When exertional heat stroke (EHS) is suspected for an athlete, CDPH recommends the following:

  • Cool first and transport second. Cooling treatment must be provided immediately, before being transported by emergency medical services.
  • Remove all equipment and extra layers of clothing.
  • Cool the athlete as quickly as possible within 30 minutes via whole body cold or ice water immersion (place the athlete in a tub with ice and water approximately 35-58 degrees F).
  • Stir water and add ice throughout cooling process.
  • If cold-water immersion is not possible (no tub), aggressively douse the athlete’s whole body with cold water. Or if that’s not possible, take the athlete to a shaded, cool area and use rotating cold, wet towels to cover as much of the body surface as possible.
  • After cooling has been initiated, activate emergency medical system by calling 9-1-1.

Air Quality

Poor air quality exacerbates risks associated with extreme heat.

The American Lung Association reports on two of the most widespread and dangerous air pollutants, fine particles and ozone. Fresno has the worst short-term particle pollution in the nation. City Rankings | State of the Air | American Lung Association. Widespread wildfires also degrade air quality. To learn more, visit the CDPH site: Wildfire smoke (ca.gov).

The Environmental Protection Agency (EPA) updates air quality reports on a daily basis for all regions of the country. AQI data is posted on the AirNow website. The AirNow AQI reports are the basis for the California Dept of Education recommendations for steps for schools to take when air quality is poor School Air Quality Activity Recommendations - Air Quality (CA Dept of Education). The CIF Extreme Heat and Air Quality Policy states:

  • Member schools should consider shortening or cancelling outdoor athletic events (practices or competition) in accordance with AQI recommendations. Exposure to air should be managed more carefully for students with pre-existing lung or heart conditions. When the AQI rises above 100 schools should consider removing such athletes at risk from practice or competition.
  • At AQI values above 150 serious considerations should be given to rescheduling the activity or moving it indoors if possible. Prolonged exposure and heavy exertion should be avoided.

To protect the health and safety of our youth, FCDPH strongly recommends that all school districts in Fresno County adopt the CIF and the California Department of Education School Air Quality Activity Recommendations.
