Updated July 29, 2025 – Heat Advisory Extended Through Wednesday
With dangerous heat dome conditions pushing temperatures to 97°F and feels-like temperatures to 107°F, Manhattan’s dense urban environment and towering buildings create intense heat island effects. This guide provides essential medical information and resources for residents, workers, and visitors navigating heat emergencies in the nation’s most densely populated area.
Immediate Heat Emergency Warning Signs
Call 911 immediately for these life-threatening symptoms:
- Heat Stroke (Critical Emergency):
- Core body temperature 104°F or higher
- Severe mental confusion, disorientation, or unconsciousness
- Hot, dry skin OR profuse sweating that suddenly stops
- Rapid, strong pulse (over 100 beats per minute)
- Severe headache and dizziness
- Nausea, vomiting, or seizures
- Difficulty breathing or hyperventilation
Seek urgent medical care for Heat Exhaustion:
- Heavy sweating with cool, moist skin
- Weakness, fatigue, or feeling faint
- Muscle cramps (especially calves and abdomen)
- Nausea or vomiting

Manhattan’s Urban Heat Island Effect
Manhattan’s unique geography creates extreme heat concentration:
Highest Risk Areas:
- Midtown West/Times Square: Concrete density, limited tree coverage, massive crowds
- Financial District: Tall buildings creating “canyon effect,” limited green space
- Harlem: Historic heat vulnerability, aging infrastructure
- Lower East Side: Dense housing, limited air conditioning access
Moderate Risk Areas:
- Midtown East: Some green spaces but heavy traffic and concrete
- Hell’s Kitchen: Mix of new and old buildings, some tree-lined streets
- Upper West Side: Better tree coverage but still densely built
Lower Risk (Relatively):
- Upper East Side: Central Park proximity, more green space
- Greenwich Village/SoHo: Lower buildings, some tree coverage
- Riverside areas: Hudson and East River waterfront breezes

Medication Safety During Heat Waves
High-Risk Medications in Extreme Heat:

- Antihistamines: Benadryl, older allergy medications – decrease heat tolerance
Never stop medications without medical supervision. Instead, consult healthcare providers about:
- Timing medication doses during cooler parts of the day
- Increased monitoring during heat waves
- Hydration strategies while taking diuretics
- Alternative medications if heat sensitivity is severe
Immediate First Aid for Heat Emergencies
For Heat Exhaustion (While Awaiting Medical Care):

- Hydrate carefully:
- Small sips of cool water if conscious and able to swallow
- Sports drinks for electrolyte replacement
- Avoid alcohol or caffeine
- Position appropriately:
- Elevate legs slightly
- Monitor breathing and responsiveness
For Heat Stroke (Call 911 Immediately):

- Monitor vital signs:
- Check breathing and pulse
- Be prepared to perform CPR
- Do NOT give fluids if person is unconscious or vomiting
Manhattan-Specific Emergency Considerations
Transportation During Heat Emergencies
- Subway platforms can reach dangerous temperatures – minimize time waiting
- Taxis and rideshares may have limited AC – request confirmation
- Walking distances should be minimized during peak heat hours (10 AM – 6 PM)

High-Rise Building Challenges
- Elevator outages during power strains trap residents on upper floors
- Top floors become dangerously hot as heat rises
- Limited balcony access reduces cooling options
- Crowded stairwells become heat traps during emergencies
Workplace Heat Safety
Manhattan workers face unique heat challenges:
- Construction sites: Mandatory cooling breaks and hydration
- Food service: Kitchen heat combined with outdoor temperatures
- Delivery workers: Multiple heat exposures throughout the day
