How ice pops could help older adults stay cool and hydrated
The Growing importance of hydration in an ageing population
As global temperatures rise, heat-related health issues are becoming a growing concern, particularly for older adults. Seniors often face a double challenge: they’re more susceptible to dehydration, and their bodies struggle to regulate temperature efficiently.
Hydration plays a critical role in maintaining body function, circulation, and cooling. But traditional hydration advice, “just drink more water” might not be enough. New research from the University of Brighton, led by Dr. Neil Maxwell, is exploring a refreshing and simple idea: could an ice pop or ice slurry protect older adults from heat stress?
This fascinating research was recently featured by BBC News, highlighting how ice-based cooling could provide an accessible, low-cost way to help older individuals stay safe in hot weather.
The Research
Dr. Neil Maxwell and his team at the University of Brighton’s Environmental Extremes Laboratory are investigating whether ice slurries, drinks made of semi-frozen water and ice particles, can prevent harmful physiological effects during heat exposure.
In their controlled experiments, older volunteers drink a measured amount of ice slurry before being exposed to warm environments. Researchers then monitor changes in core body temperature, gut integrity, and markers of heat stress.
Why does this matter? Because excessive heat doesn’t just make us uncomfortable, it can affect our internal organs. One of the study’s focuses is how heat can increase gut permeability (sometimes referred to as “leaky gut”), allowing bacteria and toxins to enter the bloodstream. This can contribute to inflammation and illness, and it’s more pronounced in older adults.
By cooling the body from the inside out, ice slurries might reduce this risk, potentially improving safety, comfort, and hydration efficiency during heat exposure.
The science of ice cooling
The principle is simple but powerful: when the body ingests something cold, particularly something semi-frozen, it requires energy (in the form of body heat) to melt it. This process absorbs heat from the body’s core, effectively lowering internal temperature faster than a standard drink.
It’s the same reason athletes frequently use iced refreshments before training or competing. Dr. Maxwell’s work extends this concept beyond performance, to everyday wellbeing, especially in older populations.
Some early findings from similar studies suggest that consuming ice slurries before exposure to heat can:
- Lower core body temperature more effectively than chilled water
- Delay the onset of heat strain and fatigue
- Reduce heart rate and perceived exertion during activity
- Improve hydration comfort and compliance (because cold drinks feel more refreshing)
Why older adults are at higher risk
As we age, our thirst response weakens, meaning older adults often don’t feel thirsty until dehydration has already set in. At the same time, natural changes in kidney function and body composition can reduce the ability to conserve water.
The result? Even mild heat or missed hydration can lead to dizziness, fatigue, confusion, or in severe cases, heat exhaustion and stroke.
Cooling and hydration strategies need to be simple, effective, and enjoyable. That’s where ice pops and ice-based supplements can make a real difference.
They offer:
- Better sensory appeal (cool, refreshing, easy to consume)
- Lower core temperature for longer
- Steady hydration without needing large fluid volumes
For carers, families, or individuals managing hydration in the elderly, these small changes can help maintain comfort and safety through warm months.
From research to the real world
Dr. Maxwell’s study represents an exciting bridge between academic research and practical application. If future results confirm the benefits of ice-based cooling, we could see recommendations for frozen hydration strategies integrated into elderly care, community health programs, and even clinical settings.
At icesupp, this aligns perfectly with our philosophy, combining science and innovation to help people stay hydrated and nourished to perform better, and feel their best.
Our ice-based supplements are inspired by the same scientific principles: cooling from the inside out while providing balanced nutrients to support total hydration.
Tips to support the elderly during hot weather
Here are a few practical ways to put the science into action, whether you’re caring for an elderly loved one or staying active yourself:
- Offer cold refreshments, often: Encourage chilled water, ice pops, or light electrolyte drinks throughout the day.
- Hydrate before exposure: Have a cool drink before going outdoors or engaging in activity, it’s easier to maintain hydration than catch up.
- Use frozen treats wisely: Sugar-free or low-sugar ice pops are a great option for cooling without excess calories.
- Monitor hydration signs: Watch for dry mouth, reduced urination, confusion, or fatigue, all early signs of dehydration.
- Keep it consistent: Encourage small, frequent sips rather than large amounts all at once.
icesupp: The future of smarter hydration and nourishment
At icesupp, we’re passionate to help everyone stay hydrated and nourished - from athletes to older adults, children and also those recovering from illness.
We believe the future of hydration goes beyond the bottle, it’s about how you cool and nourish your body, not just how much water you drink.
Conclusion
Dr. Neil Maxwell’s research at the University of Brighton offers a refreshing reminder: sometimes, the simplest solutions can make the biggest impact. By understanding the role of cold hydration, whether through ice slurries, ice pops, or advanced hydration products, we can help older adults stay safer, more comfortable, and better hydrated in a warming world.
Stay cool. Stay hydrated. Stay healthy.
As you think about your hydration strategy, consider adding ice-based hydration to your daily routine. It’s simple, effective, and backed by growing scientific interest.
