From backyard BBQs to beach days to impromptu cookouts, here's exactly what to load in your cooler—and how to keep it ice-cold even when the mercury hits triple digits.

Rule 1: Pre-chill everything. Never put warm drinks in a cooler.
Rule 2: Aim for 2:1 ice to drinks ratio.

Frequently Asked Questions
What drinks stay coldest longest in a cooler?
Canned drinks stay coldest longest because metal conducts cold efficiently. Glass bottles are second. Plastic bottles warm up fastest.
How do you keep drinks cold for 24 hours?
Pre-freeze drinks, use block ice (not just cubes), maintain 2:1 ice ratio, keep in shade, open rarely, and consider a high-end cooler like YETI.
What are the best drinks for dehydration in summer?
Water is fundamental. Add electrolyte drinks like Electrolit, Liquid I.V., or Pedialyte for serious hydration. Coconut water is excellent for natural electrolytes.
Is it better to drink cold or room temperature water?
Cold water is absorbed faster and helps lower body temperature during heat exposure. For summer heat, cold water is generally better.
How much water should you drink on a hot day?
About 8oz every 15-20 minutes during activity in heat, or about a gallon throughout a hot day. Increase if sweating heavily.
