From the pros at Dustproof Supply: We've been doing festivals since the late '80s, Dead tour on up, and the people who crash a Saturday aren't usually short on opinions. They're short on water they actually drank, food they actually ate, and shade they actually sat in. A hydration plan is that boring trio, written down before you're already behind.
This is not a medical plan. NIOSH writes its numbers for workers in hot jobs. MedlinePlus describes dehydration for patients and their clinicians. Use both as the public-health baseline, then follow your own clinician if anyone has told you to limit fluids. If someone in your crew is confused, fainting, or stops making sense in the heat, skip the blog and get to the festival medical tent or emergency services.

The short version
- Camp water and carry water are different jobs. A jug in the shade does not help you at the rail.
- NIOSH's benchmark for moderate work in the heat, under two hours, is about 1 cup (8 ounces) every 15 to 20 minutes. That is roughly 24 to 32 ounces an hour. Don't treat it as a dare to chug.
- The same guidance says fluid intake generally should not top about 6 cups (48 ounces) an hour. More is not safer.
- For sweating that goes on for several hours, NIOSH says a sports drink with balanced electrolytes is an option. Regular meals replace salt for a lot of people. NIOSH does not recommend salt tablets.
- CDC's heat page uses urine color as a rough check: light yellow or clear usually means you're drinking enough.
- If the water is cold and the bottle is clipped to you, you will drink it. Warm plastic at 3 p.m. is how people stop.
What the official numbers actually cover
We want the numbers in the open, with the conditions still attached, because festival blogs love to turn "a cup now and then" into "a gallon an hour" and call it safety.
On NIOSH's workplace heat recommendations, for moderate activity in the heat lasting less than two hours, workers are told to drink 1 cup (8 ounces) of water every 15 to 20 minutes. The older NIOSH hydration card puts the same pace at three-quarters to one quart an hour, which is 24 to 32 ounces. It also says drinking smaller amounts more often works better than a rare huge gulp, and that you should drink before you feel thirsty. By the time you're thirsty, you're already behind.
That card's ceiling matters as much as the floor. Do not drink more than 48 ounces (a quart and a half) an hour. NIOSH's reason is plain: drinking too much water or other fluid can become an emergency because the concentration of salt in the blood gets too low. The recommendations page says the same thing as "generally, fluid intake should not exceed 6 cups per hour." Six cups is 48 ounces. Same line, two pages.
A festival day is not a two-hour work bout in a measured job. Some hours you're walking a long camp road in the sun. Some hours you're standing in a crowd. Some hours you're asleep. Use the cup-every-15-to-20-minutes figure for the hard, hot, moving stretches. Use ordinary thirst-plus-a-schedule the rest of the time. Do not multiply the work rate by 14 waking hours and then try to hit it. That is how the ceiling gets ignored.
CDC's public heat page is the everyday version: carry a bottle, drink and refill it, and check urine color. Light yellow or clear usually means enough. MedlinePlus lists dark-colored urine, a very dry mouth, less urine than usual, dizziness, and feeling tired among adult dehydration symptoms. It also says to get medical help right away if symptoms include confusion, fainting, lack of urination, rapid heartbeat, or rapid breathing. Those lists are there so you recognize trouble. They are not a checklist for you to diagnose a friend in a tent.
Water, salt, and food
NIOSH is blunt that water is generally enough during work in the heat if you eat regular meals, because meals replace the salt you sweat out. The agency does not recommend salt tablets. For sweating that lasts several hours, it says sports drinks with balanced electrolytes are another option. It also notes that a lot of sports drink means a lot of sugar.
MedlinePlus says the treatment for mild dehydration is replacing fluid and electrolytes, that water may be enough in mild cases, and that sports drinks may help if electrolytes were lost. It adds the same caution: some sports drinks are sugary, so don't overdo them. It says to avoid drinks with sugar and caffeine when you're trying not to get dehydrated, and CDC's heat page says to consider limiting drinks high in sugars, sodium, caffeine, and alcohol.
Translated out of the pamphlet voice: eat real food at camp. A salty meal and a bottle of water does a job that a pocket full of sticks can't finish. Bring electrolytes for the long sweaty stretch, not as a meal, and don't use them as permission to skip lunch.
Three mixes, and what they are not
We've used Soft Landings' Dance Fuel ourselves. It's an electrolyte drink mix made for a long night of dancing rather than a gym session, and the label is sugar-free and caffeine-free. We tear a sachet into the bottle before we leave camp so the salt and the water go in together. It is not dinner, and it is not a heat-illness treatment. If a salty, no-sugar mix is what you'll actually drink, Dance Fuel is the one we use.
The electrolyte multipack on the shelf is Liquid I.V. Hydration Multiplier, a widely stocked stick with more sugar than the zero-sugar options. Fine if you want the sweet version and you eat around it. The zero-sugar high-sodium packets are the saltier end. They are still a drink mix, not a prescription, and you don't need a whole box for a mild weekend with shade and short walks.
The morning after is a separate shelf. We've used Soft Landings' Post Party Recovery Drink ourselves. It's a next-day wellness mix, not medicine and not a substitute for plain water, food, or sleep. Stir one sachet into cold water if you want it in the routine. Then eat breakfast and drink water that isn't a packet.
Build the plan in three containers
Camp water
A collapsible 5-gallon jug lives in the shade, not in the sun beside the tent. Five gallons is a camp reservoir for drinking and cooking, not a personal trophy. Refill it when you're already at the spigot, not when the last cup is gone at midnight. Mark it. Unmarked jugs become dishwater.
NIOSH tells employers to keep drinking water cool, under 59°F (15°C), and close to the people working. You are not an employer, but the reason travels: lukewarm water in the sun gets ignored. A cooler backpack keeps a few bottles honest between the jug and the chair. The kitchen packing list is where the jug starts competing with dishwater. Decide that fight on day one. Drinking water gets its own container.
Water on your body
The carry bottle is the one that decides the afternoon. We've used Soft Landings' drink mixes, and we trust a cold bottle that stays attached. The 700ml Soft Landings bottle is double-wall, about 24 ounces, with a loop for a carabiner or a pack strap. A 32-ounce wide-mouth bottle takes ice and a powder without a funnel, and it survives a wagon. It is not insulated, so it won't stay cold all day. Mark your name. Identical bottles vanish in group camps.
If the venue checks bags, start with a clear pack. The RAVERUNNER clear 2L is the gate-friendly day pack. Policies differ. Read the fest PDF the week you leave, and read the clear-bag packing list before you argue with security. An opaque pack can still be the right tool once you're back in camp. The desert day hydration pack is that workhorse, not the thing we lead with at a clear-bag gate.
Fill a new bladder at home and leave it on a towel overnight. A leak in your kitchen is a better story than a leak in your tent. Empty it before the drive home, and clean it the way the maker says. Dust and old drink mix in a capped tube is a cleanup problem, not a hydration strategy.
A kit if you want the pile pre-chosen
The Desert Day Kit is the short version: hydration plus electrolytes, sold as separate listings that may show up in more than one box. Use it if you want the starter stack. Skip it if you already own a pack and a jug and you only need salts.
A day that doesn't depend on feeling thirsty
- Morning. Drink a full bottle with breakfast before you walk anywhere. Eat something salty enough to count as food. Fill the carry bottle and the pack. Put the jug back in the shade.
- Hot moving hours. Use the NIOSH pace as a reminder, not a scoreboard: a cup or so every 15 to 20 minutes while you're actually working in the heat, and stop well short of 6 cups in any single hour. Sit in real shade between pushes. The tent-cooling guide is why that shade should not be a closed tent at noon.
- The set. If you won't hold a bottle while you dance, the pack is the plan. If you only have a bottle, clip it on. A bottle on a blanket is a bottle for strangers.
- Back at camp. Refill before you sit down. Eat. If you've been sweating for hours, this is the window for an electrolyte mix plus a real meal, which is what NIOSH is pointing at when it talks about salt from food.
- Next morning. Plain water first. Food. Sleep that got cut short does not get fixed by a packet. A recovery drink can sit in that routine. It doesn't replace it.
NIOSH also describes heat acclimatization for workers as a process over several days of gradually longer heat exposure. Most of us fly or drive in from air conditioning and start walking at noon. You will not become acclimatized on a Friday. The practical reading is humble: the first hot afternoon is the one to shorten, with more shade and an earlier refill, not the one to spend proving you don't need water.
When to stop troubleshooting and get help
CDC's heat-illness page separates a bad afternoon from an emergency. Heat exhaustion, in their description, shows up as headache, nausea, dizziness, weakness, thirst, heavy sweating, and less urine. Heat stroke is the one they mark as life-threatening: confusion, slurred speech, passing out, seizures, very high body temperature, and skin that may be hot and dry or still sweating. Their instruction for heat stroke is to get emergency care. At a festival, that means the medical team and 911, whichever is faster to reach. Tell the people you're with where medical is before the hot day, not during it.
Don't try to "fix" confusion with another packet. Move the person to shade if you can do it safely, and get the medics.
Where these numbers come from
- NIOSH workplace heat recommendations: cup every 15 to 20 minutes for moderate heat under two hours, electrolytes when sweating lasts several hours, and the 6-cup hourly ceiling.
- NIOSH heat-stress hydration card (PDF): 24 to 32 ounces an hour, drink before thirst, and the warning not to pass 48 ounces an hour.
- CDC Heat and Your Health: carry a bottle, and urine that is light yellow or clear.
- CDC/NIOSH heat-related illnesses: heat exhaustion and heat stroke symptoms, and the instruction to get emergency care for heat stroke.
- MedlinePlus dehydration page, from the National Library of Medicine: symptoms, when to get help, and the note on sports drinks and sugary fluids.
FAQ
How much water should I drink at a festival? For moderate activity in the heat under two hours, NIOSH says about 1 cup every 15 to 20 minutes, and generally not more than 6 cups in an hour. A full festival day mixes hard hours and easy ones, so use that pace on the hard stretches, drink before you're thirsty, and check that urine is light yellow. People on fluid limits should follow their clinician.
Do I need electrolytes or is water enough? NIOSH says water is generally enough if you eat regular meals, and that sports drinks are an option when sweating goes on for several hours. Salt tablets are not their recommendation. Electrolyte mixes are drink mix, not medicine.
Is a hydration pack better than a bottle? You usually want both. A pack or a clipped bottle is what you drink while you walk. A shaded jug is what you refill from. A bottle left on a blanket is neither.
Can I count beer, energy drinks, or soda? CDC and MedlinePlus both steer people away from alcohol and from drinks heavy in sugar or caffeine when the goal is hydration. Have them if you're going to have them. Don't put them in the water column.
What if I feel worse after drinking a lot, very fast? NIOSH warns that too much fluid in a short time can drop the salt concentration in your blood. Stop chugging, and get medical help if you feel seriously unwell. More water is not always the answer.
