Hydration Doesn’t Clock Off in Winter

You may not feel hot. You may not feel thirsty. But cold days, long calls, layers and physical work can still dry you out.

Most crew remember hydration in summer but Winter is easier to miss.

When it is cold, wet or windy, you may be more focused on staying warm, keeping gear dry, getting through the next setup or making the move to a new location.

But your body is still working hard.

And even when Unit is doing a great job keeping crew fed, watered and caffeinated, it is still worth keeping an eye on your own hydration throughout the day.

Why winter dehydration catches crew out

Cold-weather dehydration can happen because:

  • You do not feel as thirsty
  • You may drink more coffee or tea than water
  • You are wearing thermals, wet-weather gear or PPE
  • You are working long physical days
  • You are moving between cold exteriors and warm interiors
  • You are talking, lifting, driving, rigging, running, resetting or standing for hours
  • Your water bottle is in the truck, at base, in your bag or nowhere near you
  • Toilet access can be awkward on location, so you may avoid drinking enough

None of this means anyone is doing anything wrong - It's just set life.
That is why hydration needs to be something each of us keeps in mind, especially in the colder months.

Signs you might need more water

Dehydration does not always feel obvious at first.

It can show up as:

  • Headache
  • Dry mouth
  • Dizziness
  • Tiredness
  • Muscle cramps
  • Feeling weak or shaky
  • Brain fog
  • Slower reactions
  • Irritability
  • Finding it harder to concentrate
  • Dark-yellow urine


On set, those things matter.

Crew are often working around vehicles, gear, cables, weather, cast, crowds, tight timings and fast decisions. Staying hydrated helps you stay sharp, steady and safe.

Quick crew habits that help

You do not need to overthink it.

A few small habits can make a big difference:

  • Start the day with water, not just coffee
  • Keep a bottle where you can actually see it
  • Take water with you when moving away from base
  • Sip regularly rather than waiting until you feel thirsty
  • Drink water at meal breaks
  • Have water before long exterior setups
  • Refill when you get the chance
  • Alternate hot drinks with water
  • Watch for headaches, dizziness or brain fog
  • Check in with anyone who looks unusually wiped out or off their game

A good rule of thumb:
If you are thinking, “I should probably drink some water” - you probably should.

Hot drinks help - but water still matters

A hot drink on a cold set can be magic.

Coffee, tea and hot drinks absolutely have their place, especially on winter shoots, night shoots and exposed locations.

But they are not always a substitute for water.

If you are cold, busy, layered up or physically active, try to keep water in the mix as well.

Before you head to set

A quick personal hydration check:

  • Have I had water this morning?
  • Do I have a bottle with me?
  • Can I access it easily during the day?
  • Do I know where I can refill?
  • Am I relying only on coffee?
  • Am I already getting a headache?
  • Is my urine darker than usual?

Nothing dramatic.
Just a quick check-in with yourself.

Looking out for each other

Good crew look after the work.

Great crew also look after each other.

That can be as simple as:

  • Offering to grab someone water when you are heading past Unit
  • Reminding your department to refill before a big move
  • Checking in with someone who seems dizzy or unusually quiet
  • Making sure newer crew know where to get water
  • Not brushing off signs that someone may be struggling

Hydration is not a big speech.
It is a small, practical part of getting through the day well.

Crew care is year-round

Crew are used to pushing through.

But looking after yourself is not being precious. It is part of doing the job properly.

Water, food, warmth, rest and toilets are all basic parts of keeping people safe and able to work well.

So even in winter, keep the bottle nearby.

Have a sip between setups.

Refill when you can.


Look after yourself, and keep an eye on the crew around you.
Hydration is not just a summer safety message. It is year-round crew care.
