Spring Heat in Fresno Sparks Health Warnings Across Central Valley

Although summer is still weeks away, the recent spring heat in Fresno has already pushed many residents outdoors to enjoy the warmer temperatures while taking extra precautions against the heat.

Spring heat in Fresno increases health concerns

At Rotary East Park on Cedar Avenue, one Fresno couple adjusted their daily routine to keep their pets safe during the unusually warm conditions.

Mark and Vickie Burger, who walk their dalmatians every day, said they arrived at the park earlier than usual on Monday morning to avoid the hottest part of the day.

“The asphalt gets hot, and I don’t want them burning their feet or becoming overheated. Dogs can get heat stroke very easily,” Mark Burger explained.

They were far from alone. Before noon, the park was already busy with parents, dog owners and pickleball players taking advantage of the early hours before temperatures climbed higher.

As the spring heat in Fresno continues, health experts warn that rapid temperature changes can create additional problems, especially for people with allergies or respiratory conditions.

Drone footage across the Central Valley showed hazy skies lingering over the area as temperatures fluctuated dramatically from day to day.

Dr. A.M. Aminian of the Allergy Institute said sudden swings between hot and cool weather can irritate sensitive airways.

“The heat brings its own issues, but quick weather shifts from very hot to much cooler temperatures can also affect people,” Aminian said.

According to Aminian, changes in temperature and air pressure may inflame the bronchial tubes, making breathing more difficult for people with asthma or allergies.

“This kind of temperature and pressure change irritates the airways, especially if someone already has sensitive lungs,” he explained.

He added that spring heat in Fresno may trigger stronger allergy and asthma symptoms, including coughing, chest tightness and shortness of breath. Many of these symptoms are intensified by seasonal pollen levels.

Aminian stressed the importance of using the correct inhaler and understanding the different types available for treatment.

“There are several kinds of inhalers. Some use powder medication that you inhale deeply,” he said.

To stay safe during warmer weather, Aminian recommended taking allergy medicine regularly, drinking electrolyte-rich fluids, staying indoors during peak afternoon heat and avoiding strenuous outdoor activity whenever possible.

Mark Burger said he relies on simple precautions to manage seasonal conditions.

“I don’t have too much trouble with it. I just stay cool and take allergy medicine regularly, which helps,” he said.

Aminian also advised Fresno residents to keep windows closed during the early morning and nighttime hours, when pollen and airborne particles are more likely to enter homes and worsen allergy symptoms.

People who spend time outdoors should shower and change clothes afterward to remove allergens from their skin and hair. Drinking plenty of water, staying in cool indoor environments, and taking allergy medication regularly may also help manage symptoms. 

Experts additionally recommend limiting strenuous outdoor activities during the hottest part of the day and checking local air quality and pollen forecasts before making outdoor plans.
