Here’s What the Science Says…
Waking Up Regretful after a night out? Let’s Talk Ice Baths
You wake up with a pounding headache, a dry mouth, and a severe case of “Why did I do that?” Your body feels like it was hit by a truck, and moving from your bed seems like an impossible task. But then, you remember that one friend who swears by ice baths for everything, from sore muscles to boosting energy. Could it help your hangover too? Let’s dive into the chilly science of it all!
What Happens to Your Body During a Hangover?
Before we plunge into the icy depths, let’s explain why you feel like a human raisin after a night out. Hangovers happen because alcohol wreaks havoc on your system in multiple ways:
Dehydration: Alcohol is a diuretic, meaning it makes you lose fluids fast, leaving you parched and dizzy.
Inflammation: Your body sees alcohol as a toxin and triggers an inflammatory response, leading to headaches, muscle aches, and general misery.
Blood Vessel Dilation: Alcohol causes your blood vessels to widen, which can contribute to those pounding headaches.
Toxin Buildup: Your liver is working overtime to break down alcohol into acetaldehyde, a nasty compound that contributes to nausea and sluggishness.
Now, where does an ice bath fit into all this?
How Ice Baths Might Help with a Hangover
1. Boosts Circulation
When you plunge into icy water, your blood vessels constrict (vasoconstriction). Once you step out, they rapidly dilate (vasodilation), improving circulation and helping your body flush out toxins more efficiently. More oxygen-rich blood flowing through your system might just help shake off that sluggish, foggy feeling.
2. Reduces Inflammation
Cold therapy is well known for reducing inflammation (Espeland, D.; et al. (2022)) why athletes use it for muscle recovery. Since hangovers cause inflammation in the brain and body, an ice bath might help dial down those aches and pains.
3. Revitalises Energy Levels
Have you ever noticed how a cold shower wakes you up instantly? That’s because cold exposure triggers the release of adrenaline and dopamine, giving you a natural energy boost. When you’re battling the post-drinking blues, a jolt of cold might be just what you need to snap out of it.
4. Aids Hydration & Recovery
While an ice bath doesn’t directly rehydrate you, it can lower your core body temperature, making it easier to retain fluids and aid recovery (Chauvineau, M.; et al. (2021)). Plus, feeling refreshed might encourage you to drink more water (which is the real MVP of hangover recovery).
The Limitations - What Ice Baths Can’t Fix
Before you go diving into a tub of ice cubes, here are a few things to keep in mind:
- It won’t magically sober you up – Your body still needs time to metabolise alcohol.
- It won’t replace lost electrolytes – You’ll still need to replenish with water, coconut water, or an electrolyte drink.
- It’s not for everyone – If you have heart conditions, are sensitive to cold, or have low blood pressure, an ice bath might do more harm than good.
How to Use Ice Baths for Hangover Recovery
If you’re feeling brave and want to give it a go, here’s how to do it safely:
Best Time to Ice Bath: The morning after, when you’re fully awake and have had some water.
Ideal Temperature: 10-15°C (50-59°F). Too cold, and it could be a shock to your system.
Duration: 3-5 minutes is enough to get the benefits without overdoing it.
Pair it With: Hydration, a good meal, and rest, for a full recovery strategy.
Final Verdict: Hype or Help?
So, can an ice bath cure your hangover? Not exactly. While there is no definitive scientific study confirming that ice baths or cold plunges can cure hangovers, some research suggests that cold-water immersion may alleviate certain hangover symptoms. Science suggests it can ease fatigue, inflammation, and sluggish circulation. If you can handle the cold shock, it might be worth a try! Just don’t forget the golden rule: hydrate, eat well, and maybe pace yourself next time.
