You overdid it. Food. Booze. Life.
Here’s why sauna (and a cold dip) actually helps. Bank holiday does what it always does. One more drink.One more takeaway.Sleep’s off. Head’s fuzzy. Body feels… slow. You wake up and think:“Right. I’ll just ride this out.” But here’s the thing — you don’t have to just sit in it.

Sauna, done properly, can genuinely shift how you feel. Not magic. Just physiology doing its job.
First off — what’s actually going on in your body?
It’s not just a “hangover”.
You’ve got a mix of things happening:
– Mild dehydration– Electrolytes out of balance
– Inflammation (your body is literally irritated)
– Blood sugar swings– Poor sleep → nervous system is off
And yeah… your liver’s busy trying to clean up the mess.
So you feel flat, anxious, tired, a bit grim.
Sauna: why it helps
When you get into a hot sauna, a few things kick in:
1. You start sweating — properly
Not a light sweat. A proper one.
That helps shift fluid through the body, increases circulation, and supports what your liver and kidneys are already trying to do.
You’re not “sweating out alcohol” — that’s a myth. But you are helping your system move things along.
2. Blood flow goes up
Heat pulls blood out to the skin.
That means better circulation overall → more oxygen, more nutrients moving around, waste getting cleared more efficiently.
You basically turn your internal “flow” back on.
3. Nervous system reset
This is the big one most people don’t clock.
After a heavy night, your nervous system is often stuck in a weird place — a bit wired, a bit flat.
Sauna (especially when you stay long enough and relax into it) pushes you toward parasympathetic mode.
That’s your rest, digest, recover state.
You feel it as:– shoulders dropping– breath slowing– mind quietening
That’s not just “nice” — that’s recovery cos your body relaxes enough to start to repair.
4. Endorphins + dopamine shift
You come out feeling better not just because you’ve “done something good”…
…but because your brain chemistry actually changes.
Heat stress → endorphin release
Then if you add cold → dopamine spike that can last hours
That “I feel human again” feeling?
That’s real.
And the cold dip?
This is where it all sharpens up.
Cold water does a few key things:
– Reduces inflammation
– Sharpens your nervous system (clean alertness, not jittery)
– Gives you a proper dopamine lift
It cuts through that groggy, sluggish feeling fast.
But… don’t be a hero here.
If you’re already depleted:→ keep it short→ stay in control of your breathing→ get warm again properly after
The bit people get wrong
They go too hard.
Too hot. Too long. No water. No salt. Straight in like they’re proving something.
That’s how you feel worse.
Instead:
– Drink water before you even get in
– Add some salt or electrolytes
– Take it steady (multiple rounds > one long smash)
– Sit down. Breathe. Slow it all down
You’re not “battling” the hangover.You’re helping your body out of it.
The honest truth
Sauna won’t erase a heavy weekend.
But it will:
– take the edge off faster
– bring your energy back
– calm the nervous system
– help you feel like yourself again
And mentally… that shift matters.
You go from “I feel rough”to“Alright… I’m back.”
If you’re coming in this weekend
Don’t overthink it.
Turn up a bit fragile if that’s where you’re at. Happens to all of us.
We’ll get you warm. Get you breathing again. Maybe a cold dip if you fancy it.
And you’ll walk out feeling different. Lighter. Clearer.
Not perfect. Just… better.
And sometimes that’s exactly what you need.
