If you work outdoors, especially in the heat, you know how intense it can get. Sun beating down, sweat dripping, clothes soaked… Even if it doesn’t bother you mentally, your body still takes a hit physically. That’s why knowing how to stay hydrated at work is so important.
Even on cool days, physical activity increases your risk of dehydration. Being mindful of water intake keeps you alert and energized throughout the day.
Here’s how you can feel better, stay healthy, and get the job done by staying hydrated while working outdoors.
1. Start Your Day Hydrated

After a night’s sleep without fluids, your body wakes up dehydrated, even if you don’t feel thirsty. If you’re working outside, that hydration gap matters.
Out the door early? Drink water before leaving. Keep a bottle by your bed and sip 8–12 ounces as you wake up and get ready for work. It’s a simple way to prepare your body for the heat. If you start work later, drink 16–20 ounces of water two to four hours before work to give your body a head start.
2. Drink Water Consistently, Not Just When You're Thirsty
Once you feel thirsty, you’re already on your way to dehydration. Aim for 8 ounces of water every 15–20 minutes during active work in the heat. Spacing it out helps your body absorb fluids efficiently and prevents heat stress.
If you’re busy, you’re liable to forget, so set reminders on your smartwatch or pair hydration with tasks. For example, drink water when switching tools or after completing short project stages.
3. Go Easy on Caffeine and Sugary Drinks

Caffeine and sugary drinks like iced coffee, iced tea, and soda may give you a boost, but they can also act as diuretics and increase fluid loss. Sports drinks can help, but they’re often high in sugar, so choose carefully. Energy drinks contain high amounts of caffeine, which increases urine output and contributes to dehydration. Excess caffeine can even strain your heart. Instead of a sugary, caffeinated pick-me-up, try flavored sparkling water or a low-sugar electrolyte drink to stay alert and hydrated.
4. Use a Clean, Reusable Water Bottle
A refillable bottle makes it easier to drink water regularly and cuts down on single-use plastics. Choose a wide-mouth insulated bottle that keeps water cool and is easy to clean. If you’re on the move, use a bottle with a clip for your tool belt or backpack. If you’re in one spot, stash it in the shade and take frequent sips. Be sure to clean your bottle daily with warm, soapy water to prevent bacteria buildup.
5. Replenish Lost Electrolytes

Sweating depletes electrolytes like sodium, potassium, and magnesium. Electrolytes are essential to life and regulate hydration and nerve and muscle function, among other bodily processes. That’s why water alone might not be enough if you work long hours in sweltering heat.
Alternate plain water with low-sugar electrolyte drinks. Check with your doctor or other medical professional to see if electrolyte tablets or powders are right for you. Snacks can help, too. Bananas, oranges, dried apricots, salted nuts, pumpkin seeds, yogurt, and pickled vegetables are foods that contain electrolytes and help keep your body in balance.
6. Recognize Early Signs of Dehydration
Dehydration often creeps in slowly. Noticing symptoms before they get worse helps you stay safe and avoid heat-related illness. Watch for:
• Dry or sticky mouth and lips
• Dry skin
• Dark-colored urine
• Sunken eyes
• Headache or fatigue
• Muscle cramps
• Dizziness or lightheadedness
• Confusion or trouble focusing
• Infrequent urination (no pee for a long time)
If you notice any signs of dehydration, take a break in the shade or an air-conditioned building, sip water slowly, and rest. Don’t try to power through. Heat exhaustion or heatstroke could result.
7. Hydrate With Food

Fruits and vegetables with high water content help you stay hydrated while supplying electrolytes and other key nutrients. Here are some foods with high water content:
• Watermelon and cantaloupe
• Grapes and strawberries
• Oranges and peaches
• Cucumbers and tomatoes
• Celery, lettuce, and spinach
• Yogurt and fruit smoothies
• Cold soups like gazpacho or fruit soup
They’re light, refreshing, and easy to digest in the heat. Keep a cooler stocked with fruit slices or a salad in your truck or break area. Eat as a snack or part of lunch to help you hydrate and cool down quickly.
8. Take Short Breaks to Hydrate
Cooling off in the shade helps your body regulate its temperature and lowers the risk of heat stress. If you manage a crew, build hydration into the schedule. Plan short, five-minute hydration breaks every 30–60 minutes during hot weather and encourage workers to sip water, but don’t overdo it. Too much water can be just as dangerous as too little.
9. Rehydrate After Work

Hydration doesn’t end with work. Your body still needs fluids and electrolytes to recover, especially if you’ve been sweating for hours. On the way home, sip water or a low-sugar electrolyte drink, but skip the happy hour — alcohol dehydrates you further. Here’s a good guideline: For every pound of sweat loss, slowly drink 16–24 ounces of water over the next few hours.
10. Use Filtered Water - It Tastes Better
When water tastes bad, you’re less likely to drink enough. Tap water can contain chlorine, sediment, and other substances that turn people off, especially on job sites or in older buildings. Having easy access to water that tastes clean and fresh is how to stay hydrated at work.
Consider a Brio bottled water cooler or an undersink filtration system to fill your bottles at home or on the job. Brio filters remove up to 99% of contaminants and deliver crisp, clean-tasting water.
Stay Cool With the Right Water Setup

Whether you’re working on a job site, in a backyard, or managing a team, easy access to cool water makes hydration easier. Brio water coolers and filtration systems deliver clean water on demand without the hassle or uncertainty of tap water.
With options for home, job trailers, or shared break areas, Brio helps keep everyone hydrated and safe on the job.
Staying hydrated at work isn’t just about drinking more water — it’s about planning, building good habits, and making hydration part of your daily routine. Use these tips to stay sharp, avoid heat stress, and feel your best throughout the day.
