How fans stay safe and hydrated
Drink water steadily through the day rather than chugging at kickoff, and refill at stadium water stations — bring an empty refillable bottle if the bag policy allows it. Wear light, loose clothing, a hat, and sunscreen; take shade or air-conditioned breaks during the midday peak; and watch for dizziness or cramping as early heat-illness signs. Schedule beach time and day trips for the morning, and save indoor stops for the afternoon storm window.
