NYC heat can become dangerous fast—especially in apartments without strong airflow, on subways, and at outdoor events. The key is knowing the early warning signs, cooling early, and taking heatstroke seriously.

Heat Illness vs Heatstroke (Plain Language)

• Heat exhaustion: heavy sweating, weakness, dizziness, nausea, headache.
• Heatstroke: confusion, fainting, very hot skin, seizures, or worsening symptoms.

Prevention That Actually Works

• Hydrate early (don’t wait until you feel thirsty).
• Plan outdoor time around cooler hours.
• Use shade and airflow breaks—especially for kids and seniors.
• Check on neighbors and family members who live alone.

High-Risk Groups

• Older adults, infants/children, people with heart/lung conditions.
• Outdoor workers, athletes, and anyone without A/C.

What to Do Right Now

• Move to shade or a cooler environment.
• Cool the person (cool cloths, fan airflow, sip water if alert).
• Stop activity and rest.

When to Call 911

• Confusion, fainting, seizure, trouble breathing, or symptoms rapidly worsening.
• Any suspected heatstroke.

Train for Real Emergencies

First aid and CPR training helps you act early and recognize red flags quickly.
