Here are some quick tips on how to stay cool during New York City heat waves from the New York City Office of Emergency Management (OEM):

• If possible, stay out of the sun. When in the sun, wear sunscreen (at least SPF 15), and a hat to protect your face and head.
• Use an air conditioner if you have one. Set the thermostat no lower than 78 degrees.
   
• If you do not have an air conditioner, consider going to a public pool, air-conditioned store, mall, movie theater, or cooling center. To locate a cooling center near you, call 311 (TTY: 212-504-4115) or access www.NYC.gov/oem.
• Check on your neighbors, family, and friends, especially if they are seniors, young children, or have special needs.
   
• Fans work best at night, when they can bring in cooler air from outside.
   
• Drink fluids – particularly water – even if you do not feel thirsty.* Avoid beverages containing alcohol, caffeine, or high amounts of sugar.
   
• Wear lightweight, light-colored, loose clothing that covers as much of your skin as possible. Never leave children, pets, or those who require special care in a parked car during periods of intense summer heat.
• Avoid demanding activity, especially during the sun’s peak hours – 11 a.m. to 4 p.m. If you must engage in demanding activity, do it during the coolest part of the day, usually in the morning between 4 a.m. and 7 a.m.
• Cool showers or baths may be helpful, but avoid extreme temperature changes, as they may make you nauseated or dizzy.
• Monitor weather conditions by staying tuned to TV and radio broadcasts by accessing www.NYC.gov, or calling 311 (TTY: 212-504-4115).
