When you think of dehydration, you probably picture hot summer days - sweaty, thirsty and reaching for your water bottle.

But here’s the thing: just because it’s cold outside doesn’t mean you can’t get dehydrated. In fact, for Aussie tradies working outdoors in the cooler months, dehydration is still a real issue—and it can mess with your muscles, your joints, and even your safety on the job.

Let’s break it down and talk about why staying hydrated in winter matters just as much as it does in summer.

Why You Still Get Dehydrated in Cold Weather

When it’s cold, you don’t feel as thirsty—that’s just how our bodies work.

In fact, your brain doesn’t send the “drink now” signal as strongly in cooler weather, even when your body still needs water. That’s one of the main reasons people end up not drinking enough during winter.

And if you’re working hard outdoors—digging, lifting, climbing, or carrying gear—your body still loses fluid, whether you realise it or not. You might not see sweat dripping off your face like in summer, but you’re still sweating under your layers of workwear and safety gear. Plus, cold air is usually drier, which means you lose more moisture just by breathing.

So even if you're not hot, you’re still using up your body’s water—and if you don’t top it up, you’ll start to feel the effects.

What Happens to Your Muscles When You Don’t Drink Enough

Your muscles are made mostly of water—about three-quarters, in fact.

So when you’re low on water, your muscles don’t work as well. You might:

• Feel more tired
• Get muscle cramps
• Struggle with lifting or doing physical tasks
• Take longer to recover after a hard day

And if you're not drinking enough water, your body also struggles to move important nutrients and oxygen to your muscles. That can leave you feeling sluggish and sore—two things you don’t want when you're on the tools.

It also increases your chances of pulling a muscle or getting injured, especially when you're doing heavy work or awkward movements.

How Dehydration Affects Your Joints

It’s not just your muscles that suffer when you’re low on water—your joints do too.

Joints (like your knees, elbows, and shoulders) have a special fluid in them that acts like oil in a car engine. It keeps everything moving smoothly and pain-free. But that fluid is mostly made of water. So if you're not drinking enough, your body can’t keep those joints well-lubricated.

That can make your joints feel stiff, sore, and harder to move—especially first thing in the morning or after a long shift. For tradies doing physical jobs all day, it adds extra strain on the body and increases the risk of long-term damage or injury.

Dehydration Makes It Harder to Think Straight

Being low on water doesn’t just mess with your body—it messes with your brain too.

Even just a little bit dehydrated, you might start to:

• Feel more tired or drowsy
• Lose focus
• Make more mistakes
• React slower

And that’s not good when you’re on a job site, working with tools or machinery, or needing to keep your eye out for safety hazards. Staying hydrated helps keep your brain sharp and your body ready for action.

Signs You Might Be Dehydrated (Even If You’re Not Thirsty)

Here are some signs to watch out for, especially during winter:

• Dry lips or mouth
• Headaches
• Feeling light-headed
• Muscle cramps
• Dark yellow pee
• Trouble focusing
• Feeling more tired than usual

If you notice any of these, it’s a good sign your body’s asking for more water—even if your brain hasn’t caught on yet.

Simple Ways to Stay Hydrated in Winter

The good news is, it’s pretty easy to stay on top of your hydration once you’re aware of it.

Here are some practical tips for tradies:

1. Start your day with waterBefore you grab your morning coffee, drink a glass of water. It helps top up your tank before the workday even begins.
2. Take regular sipsDon’t wait until you’re thirsty. Try to have a small drink every hour or so—even if it’s just a few gulps.
3. Go warm if cold water puts you offIf you don’t feel like drinking cold water, have warm water or non-caffeinated tea instead. That still counts toward hydration.
4. Watch your peeA quick way to check if you’re drinking enough: if your urine is pale yellow, you're doing well. If it’s dark, you probably need more fluids.
5. Eat water-rich foodsFruit like oranges, watermelon, and apples, or even a bowl of soup at lunch, can help keep your fluid levels up.
6. Be careful with too much coffeeCaffeine (in things like coffee or energy drinks) can make you pee more, which leads to losing more water. Try to balance it out by drinking extra water.

What Employers Can Do

If you’re running a crew or managing a site, keeping your workers hydrated should be part of your safety routine.

Here’s how you can help:

• Make sure there’s clean, easily accessible drinking water on site
• Encourage short water breaks, even in winter
• Remind workers that hydration matters all year round—not just in summer
• Offer warm, hydrating options like soups or herbal teas on chilly mornings
