Friday’s high in Fresno was 104 degrees.
We aren’t expected to escape triple-digit heat anytime before July 16, the weather service said. Nighttime lows will be in the mid-70s.
The heat affects air quality and health, especially for children.
Since the summer began, Valley Children’s Hospital has seen an influx of heat-related illnesses in the emergency room, said Carlos Flores, a registered nurse and trauma coordinator at the hospital. He said it’s something that happens every year and younger children are especially susceptible. “They have a higher circulating blood volume,” he said. “Their body temperatures rise five times faster than an adult.”
Flores said symptoms of heat exhaustion include dizziness, fainting, fatigue, headache, nausea, vomiting and paleness. Heat stroke occurs when the body stops sweating and the skin becomes red hot. Seizures or loss of consciousness can happen. When children arrive at the emergency room, they are usually already on their way to cooling down, Flores said, but treatment can include putting an IV in at the hospital.
Flores said that if there is any delay in medical treatment, douse a person with ice water to help cool the body. Drinking water or a sports drink with electrolytes can also help someone entering heat exhaustion or stroke. “Never soda, never juice,” Flores warned, because of the high sugar content.
Flores said although many children visit the hospital for respiratory illnesses, he doesn’t necessarily see a spike during days with bad air quality.
Fresno’s air quality remains unhealthy for sensitive groups, according to the San Joaquin Valley Air Pollution Control District. Because of the heat, it is expected to stay that way for awhile, said district spokeswoman Cassandra Melching. As of Friday, there are no restrictions in place due to the air quality, but those sensitive to air quality should take precaution.
