How to Stay Safe in the Heat
James Tomasini, a meteorologist at the National Weather Service’s Upton office, has some very important advice:
For Everyone:
- Drink water constantly — even if you don’t feel thirsty
- Take breaks in the shade or air conditioning if you’re outside
- Apply sunscreen every 2 hours (set a timer on your phone!)
- Wear lightweight, loose-fitting clothes — think cotton, not polyester
- Drink beverages with electrolytes (like sports drinks) to replace what you lose in sweat
For Outdoor Workers:
- Take breaks as often as possible
- Watch for signs of heat exhaustion in coworkers
- Have a cool-down plan ready
Critical Reminders:
NEVER leave children or pets in vehicles — not even for "just a minute." Cars heat up dangerously fast.
Why This Heat Feels Worse Than the Thermometer Says
You might see "88°F" and think "that’s not so bad." But the heat index (what it feels like with humidity) makes it feel like 95°F.
Think of it like this: Your body cools itself by sweating. When the air is already full of moisture (humidity), your sweat can’t evaporate as easily. So your body stays hot — like wearing a wet blanket in a sauna.
Quick Checklist: Heat Safety Essentials
- [ ] Water bottle (refill often!)
- [ ] Electrolyte drinks
- [ ] Sunscreen (SPF 30+)
- [ ] Hat with a brim
- [ ] Light-colored, loose clothing
- [ ] Plan for shade/AC breaks
- [ ] Check on elderly neighbors
- [ ] Never leave kids/pets in car
Summary
| What’s Happening | What to Do |
|---|---|
| Heat advisory until Mon 7 PM | Limit outdoor activity, stay cool |
| Feels like 95°F Monday | Hydrate before you’re thirsty |
| Storms likely Mon evening | Have indoor backup plans |
| Hot through Wednesday | Keep up safety routines all week |
| Thursday storm chance | Watch forecasts, stay flexible |
Bottom line: This isn’t just "summer weather" — it’s a multi-day heat event that can be dangerous if you don’t take it seriously. Treat heat safety like you’d treat a storm warning: prepare, protect, and check on others.
Frequently Asked Questions
Q: What exactly is a "heat advisory"?
A: It’s an official warning from the National Weather Service saying the combination of heat and humidity could be dangerous to your health — especially if you’re outside for long periods, doing physical work, or don’t have air conditioning.
Q: How much water should I drink?
A: Aim for at least 8 ounces every 15–20 minutes if you’re outside. Don’t wait until you’re thirsty — that means you’re already dehydrated. If your urine is dark yellow, drink more!
Q: Are sports drinks better than water?
A: For most people, water is perfect. But if you’re sweating heavily for over an hour (like working outside or exercising), a drink with electrolytes helps replace the salt and minerals you lose in sweat.
Q: What are signs of heat exhaustion?
A: Watch for: heavy sweating, weakness, dizziness, nausea, headache, cool/moist skin, and muscle cramps. If you or someone else shows these signs: get to a cool place, sip water, and seek medical help if symptoms don’t improve quickly.
Q: Will the storms Monday evening cool things down?
A: They might bring brief relief, but the humidity will likely stay high. Don’t count on storms to "break the heat" — keep your heat safety habits going all week.
Stay cool, Long Island!
