What's at stake:
Extreme heat and prolonged exposure to high heat can be detrimental to your health. Wednesday will be the sixth consecutive day over 100 degrees in Fresno.
Fresno is likely to see it’s hottest heat wave so far this year with scorching temperatures forecast to reach 112 degrees or more for the next week.
The National Weather Service issued an excessive heat warning that will be in effect until 8 p.m. on Friday, Sept. 9.
Local medical experts are warning that extended periods of daily high temperatures over 90 degrees, let alone over 100 degrees, can be dangerous and can make it difficult for a person to regulate their body temperature.
“The longer the heatwave goes on, or the longer the temperature remains high, each successive day that people are exposed to this, their defenses wane,” said Dr. Jesus Rodriguez, a family medicine specialist with Kaiser Permanente in Fresno.
Heatstroke, which is the most serious acute heat-related illness, can lead to death if not treated quickly, said Dr. Rais Vohra, public health officer for Fresno County. Heat stroke can be caused by overheating due to prolonged exposure to heat or overexertion in high heat.
“(Heatstroke) usually means the person has unstable vital signs,” Vohra said. “They need to go to the ICU, and have critical care performed right away.”
However, less severe heat related illnesses, such as heat exhaustion or heat cramps can also lead to emergency room visits.
Here are symptoms to look out for according to the Center for Disease Control:
- Heat exhaustion symptoms include heavy sweating, fast and weak pulse, nausea, vomiting, muscle cramps, tiredness, dizziness, headache, or loss of consciousness.
- Heat stroke symptoms include high body temperature, dizziness, nausea, confusion, loss of consciousness, fast and strong pulse, and hot, red, dry or damp skin.
- Heat cramps can appear as heavy sweating during exercise and muscle pain or spasms.
- Heat rash symptoms include red clusters of small blisters, typically in the neck, chest, groin or elbow regions.
Dr. Rodriguez said that people with disabilities or pre-existing conditions, people who work outdoors, as well as children and the elderly are at a higher risk of experiencing heat related illnesses.
What to do if you are experiencing heat-related symptoms
If you are experiencing mild symptoms, such as light headaches, mild dizziness, or tiredness, here are some tips from Dr. Rodriguez to cool yourself down:
- If you are outside, get to a shaded area.
- Avoid overexertion or exercising during the hottest parts of the day, if possible.
- If you have access to water and a fan, wet your clothes down and stand in front of the fan.
- Cool down by putting ice or a cold towel on your neck, armpits or groin regions. There is a lot of blood flow in these areas which can help you cool down more quickly.
- Drink a lot of water.
- Replenish your electrolytes with low-sugar drinks.
- Avoid caffeine and alcohol if you are in the sun.
- If you’re working outside, take regular breaks out of the sun.
Rodriguez said heat-related deaths are “totally preventable” if people know what to look out for, have access to cool or shady spaces, water and can take breaks if they are working outdoors.
He stressed the importance of drinking water, adding that people who “start off the day a little dehydrated are already in danger.”
People who live and work in air conditioned areas should be drinking about 64 ounces of water per day, he said, while those that live and work in hot conditions should drink eight to 12 ounces of water, each hour they are in those conditions. People who are sweating profusely should also try to replace electrolytes.
Feeling confused, extremely dizzy, incoherent, disoriented or extremely nauseous, Rodriguez said, are signs to call 911.
“The more people know about these things I think, the more people we can save,” he said. “Sometimes it’s just a matter of having a fan and having enough water.”
