With temperatures forecast to reach dangerous levels across Passaic County from June 30 through July 6, 2026, the Passaic County Department of Health Services is urging residents to take extreme heat seriously. Heat-related illness is one of the leading weather-related causes of death in the United States — and it is preventable. 

What Is Heat-Related Illness? 

Heat-related illness occurs when the body cannot cool itself properly. Prolonged exposure to high temperatures can overwhelm the body’s ability to regulate heat, leading to a range of conditions — from mild heat cramps and heat exhaustion to life-threatening heat stroke. 

The following groups are most at risk and should take extra precautions during extreme heat events: 

• Children 

• Elderly individuals 

• People with chronic medical conditions 

Symptoms to Watch For 

Knowing the warning signs of heat-related illness can save a life. Seek medical attention immediately if you or someone around you experiences any of the following: 

• Heavy sweating, or conversely, no sweating at all 

• Dizziness or fainting 

• Nausea or vomiting 

• Rapid, weak pulse 

• Hot, red, dry skin 

• Throbbing headache 

• Muscle cramps or weakness 

• Confusion or disorientation 

• Seizures 

• Loss of consciousness 

Confusion, seizures, and loss of consciousness are signs of heat stroke — a medical emergency. Call 911 immediately. 

Prevention Tips 

Most heat-related illnesses are preventable with simple precautions. The Passaic County Department of Health Services recommends the following steps to stay safe during this heat event: 

• Stay indoors during peak heat hours, typically between 10 a.m. and 4 p.m. 

• Drink plenty of water throughout the day, even if you do not feel thirsty. 

• Wear lightweight, light-colored, loose-fitting clothing. 

• Never leave children or pets unattended in vehicles — temperatures inside a parked car can rise rapidly and become fatal. 

• Take cool showers or baths to lower body temperature. 

• Use fans and air conditioning whenever possible. 

• Limit outdoor physical activity and exercise. 

• Check on elderly neighbors, friends, and family members. 

• Apply sunscreen (SPF 30 or higher) when going outside. 

• Eat light, cool meals and avoid heavy or hot foods. 

What to Do in a Heat Emergency 

If someone shows signs of heat stroke, act quickly. Every minute counts. Follow these steps while waiting for emergency services: 

1. Call 911 immediately if the person shows signs of heat stroke.

2. Move the person to a cool, shaded area.

3. Apply cool water or ice packs to the neck, armpits, and groin to rapidly lower body temperature.

4. Fan the person while misting them with cool water.

5. Do NOT give fluids if the person is unconscious.
