Friday, 3:30 p.m. School’s out, kickoff is at 7, and the locker room smells like tape and nerves. Somebody’s eating gas-station chips, somebody else hasn’t eaten since lunch. Saturday in college and Sunday in the NFL look fancier, but the questions are the same. Football game day is about arriving fueled and hydrated, handling the heat under a helmet and pads, and using halftime well.

This page covers what to eat before a football game and when, how much to drink, why football gear makes heat a bigger deal than in most sports, and what to do at halftime. It’s built from what sports-nutrition and sports-medicine groups recommend, for youth, high school, college, pro and adult players. It isn’t personal advice; a registered dietitian or your athletic trainer can tailor it.

The pregame meal

The joint position statement on nutrition and athletic performance from the American College of Sports Medicine (ACSM), the Academy of Nutrition and Dietetics and Dietitians of Canada recommends a pre-exercise meal that is high in carbohydrate, moderate in protein, low in fat and fiber, made of familiar foods and eaten roughly 1–4 hours before. Carbohydrate tops up the fuel your muscles burn in short, hard efforts, and football is nothing but short, hard efforts.

• 3–4 hours before: a real meal. Pasta or rice with chicken, a turkey sandwich with fruit, or a bowl of oatmeal with a banana and yogurt.
• 1–2 hours before: something small and easy: a banana, a bagel, pretzels, a sports drink.
• Friday-night games: a good lunch, then a pregame snack or team meal in the late afternoon, so you’re not running on an empty tank at 7 p.m.
• Nothing new on game day. Try foods and drinks in practice first. Greasy, very fatty or high-fiber meals sit heavy under pads.

Bigger players need more food, not different food: a 300-pound lineman and a 170-pound cornerback eat the same kinds of meals in very different amounts. And skip energy drinks. The National Federation of State High School Associations (NFHS) says plainly that they are not appropriate hydration fluids, and stimulants aren’t for teens.

Hydration before, during and after

A simple starting point from the American Academy of Orthopaedic Surgeons (AAOS): about 24 ounces of non-caffeinated fluid 2 hours before, another 8 ounces of water or sports drink right before, and an 8-ounce cup every 20 minutes during activity. The NFHS adds that urine should be pale, about the color of lemonade, when you start.

Sweat rates vary a lot, especially in pads, so the National Athletic Trainers’ Association (NATA) recommends measuring them: weigh yourself before and after practice and build a personal plan. The ACSM position says losing more than 2% of body weight in fluid can hurt performance, especially in hot weather. Overdrinking is a risk too: NATA warns that drinking far more than you sweat can lead to hyponatremia (low blood sodium). The goal is to replace what you lose, not to flood yourself.

Linemen and heavy, salty sweaters often add electrolytes on hot days. Our electrolyte powder guide compares third-party tested options; for young players, water and regular meals cover most games.

Heat, helmets and the weight of the gear

Football is the sport where heat is most dangerous, and the uniform is a big reason. In a lab study of experienced linemen, researchers noted that the helmet and pads cover about half of the skin and other clothing another 20%, which traps a humid layer next to the body and blocks cooling by sweat. A related study notes that the weight of the equipment also makes the body produce more heat. In that test, exercising in the full NFL uniform drove body temperature up faster than wearing everything but the helmet and shoulder pads, and both drove it up faster than shorts and sneakers.

• Get the helmet off on the sideline when you can, and open up between series. Shade and cold towels help you feel better.
• Know who’s at higher risk: linemen, players who are less fit, recently sick, have had heat illness before or have sickle cell trait, says the NFHS.
• Watch the weather: many schools use a Wet Bulb Globe Temperature reading to change rest breaks and gear when it’s hot and humid.
• Know the emergency: stumbling, collapse, confusion or acting strangely can mean exertional heat stroke. Call 911 and start cooling on site, ideally in an ice-water tub: “cool first, transport later.” More on our football injuries page.

Warm-up and the sideline

AAOS recommends warming up for a few minutes (jogging or jumping jacks) and then stretching hips, knees, thighs and calves, because cold muscles are more prone to injury. Most teams run a set pregame routine; stick with it and include a few short sprints so your first real burst isn’t the opening kickoff. On the sideline, keep drinking at every chance, eat a little at long breaks if you’re hungry, and tell your athletic trainer about anything that hurts or any hit that left you dizzy. Players and parents: a teammate who “isn’t right” after a hit should come out and stay out.

Halftime: use every minute

Halftime is short. NFL rules set it at 13 minutes. NCAA regular-season games get 20 minutes unless both schools agree to shorten it, and high school halftime length is set by NFHS rules and state associations. A good routine:

• Cool down first: helmet off, shoulder pads loosened if there’s time, into the shade or air conditioning.
• Drink: water or a sports drink, more if you’ve been sweating hard.
• A small snack if your team allows: orange slices, a banana, a few pretzels or a gel.
• Check in: retape, change wet socks or gloves, and get anything that hurts looked at before the second half.

After the final whistle

Rehydrate and eat within a couple of hours, and keep an eye on any teammate who took a big hit: concussion signs can show up hours later. The full plan, from the first hour to the next game, is on our football recovery page. Training for the season ahead lives on the football training page, and the whole sport on the football hub.

Game-day bag

For grip in any weather, Cutters Game Day gloves are machine washable and meet the SFIA specification for NFHS and NCAA play, the maker says. For hydration, our picks from the electrolyte guide: Thorne Advanced Electrolytes (NSF Certified for Sport), Precision Fuel & Hydration PH 1500 for heavy sweaters and Nuun Sport tablets for a light, low-sugar option.

Football game-day FAQs

What should I eat before a football game?

A familiar meal that’s mostly carbohydrate with some protein and not much fat or fiber, 3–4 hours before, plus a small snack 1–2 hours before if you’re hungry. Pasta with chicken or a turkey sandwich with fruit are classic choices.

How much water should a football player drink on game day?

AAOS suggests about 24 ounces two hours before, 8 ounces right before and 8 ounces every 20 minutes while playing. Weigh yourself before and after practices to learn your own sweat rate, and don’t drink far more than you sweat.

How long is halftime in football?

13 minutes in the NFL and 20 minutes in NCAA regular-season games (unless both schools agree to shorten it). High school halftime is set by NFHS rules and your state association.

Are energy drinks OK before a game?

Not for hydration, says the NFHS, and stimulants aren’t recommended for teens. Adults who use caffeine should test it in practice first; anyone with a heart condition should ask a doctor.

Why do football players get heat illness more than other athletes?

Hard work in late-summer heat, bigger bodies on the line, and a uniform that covers much of the skin and adds weight. Together they let body heat build faster than it can escape.
