‘Dry January’ has taken on a very different meaning in 2025, as new research reveals a nationwide winter hydration gap. According to fresh data, almost 95% of Brits admit they drink less water in January, highlighting how colder months quietly disrupt healthy hydration habits.
To combat this seasonal issue, Hydration Booster by Gatorade has unveiled the world’s first science-backed “Thirst Trap” alarm – an innovative audio nudge designed to re-ignite natural thirst cues and encourage people to drink more water during winter.
Why Brits Struggle to Stay Hydrated in Winter
The new alarm was developed following findings from Gatorade’s latest hydration report, which revealed that winter weather significantly impacts drinking habits. Two-thirds of Brits (66%) say it’s harder to remember to hydrate in colder months, while 45% are unaware that cold temperatures suppress the body’s natural thirst signals — a key reason people may unknowingly under-consume fluids.
Behavioural triggers also play a major role. The research found that:
-
62% of people take a sip of water after hearing someone else drink
-
50% feel prompted to hydrate by the sound of running or pouring water
-
Yet 51% don’t feel as thirsty in cold weather
-
33% find drinking water uncomfortable or “too cold” during winter
Despite good intentions, winter remains a barrier — even as hydration continues to be a popular New Year’s resolution.
The Science Behind the ‘Thirst Trap’ Alarm
The Thirst Trap alarm uses ASMR (Autonomous Sensory Meridian Response) techniques to stimulate thirst through sound. It features audio created by Emma Smith (@WhispersRed), one of the UK’s most recognisable ASMR creators.
The layered track includes sensory cues such as:
-
The slow pour of liquid
-
The tear of a sachet
-
The fizz of a drink
-
The first crisp sip
Each sound is designed using behavioural science insights to help overcome suppressed thirst cues in cold environments.
Expert Insight: Why Sound Can Make You Thirsty
HCPC-regulated psychologist Dr Tara Quinn-Cirillo, who advised on the alarm’s development, explains:
“Our brains instinctively link sensory cues to drinking behaviour. When we see or hear thirst triggers — like water being poured, cold droplets, or fizz — this activates neurons in the amygdala, the brain’s thirst centre, motivating us to drink. Drinking releases dopamine, reinforcing this behaviour. Cold drinks, in particular, produce a stronger feeling of being quenched.”
She adds that Gatorade’s Thirst Trap blends cues like pouring, clinking and fizzing to help consumers re-engage with hydration during winter months when thirst cues are naturally muted.
Brits Want Hydration Nudges
The research also shows strong demand for simple reminders:
-
60% rely on thirst as their main cue to drink — often too late
-
48% say an audio reminder would help them hydrate more regularly
-
50% find hydration-related sounds motivating
While 64% of Brits list “drinking more water” as a New Year’s resolution, an overwhelming 84% still consume under two litres per day.
Hydration and Performance: Why It Matters Year-Round
Dr Vlad Sabou of the Gatorade® Sports Science Institute highlights why winter hydration is often overlooked but critically important:
“Maintaining hydration year-round is crucial for optimal physical and cognitive performance, but cold weather can impair thirst perception — potentially leading to an overall underconsumption of fluids. Even a 2–3% body water deficit can influence mood, increase fatigue, reduce alertness and reduce aerobic performance.”
