While we often associate hydration with simply feeling thirsty, the effects of dehydration can be far more serious, especially for vulnerable groups such as the elderly, young children, and pets.
Whether you're planning a summer stroll, working outdoors, looking after elderly relatives, or caring for a furry friend, staying hydrated in hot weather is not just good advice, it's potentially life-saving.
Why Hydration Is So Important
Water makes up a large part of our body and is essential for nearly every bodily function. It regulates temperature, supports the brain and organs, lubricates joints, and aids digestion. During hot weather, we lose more water than usual through sweat, and if we don’t replace it quickly, dehydration can occur.
Dehydration in Adults and Children
For most healthy adults, signs of dehydration can come on gradually:
Dry mouth
Headaches
Dizziness or light-headedness
Dark-coloured urine
Tiredness or confusion
Children can become dehydrated even faster, especially when active outdoors. Always ensure they have regular water breaks and avoid sugary or caffeinated drinks, which can worsen dehydration.
The Elderly: A High-Risk Group
Older adults are particularly vulnerable for several reasons:
Reduced thirst response – they may not feel thirsty even when they need fluids
Medication side effects – certain medications can increase fluid loss
Health conditions – dementia, diabetes, or mobility issues can make it harder to drink regularly
Warning signs in the elderly include confusion, lethargy, dry skin, rapid heartbeat, and even fainting. In severe cases, dehydration can lead to hospitalisation and worsen existing conditions.
Top Tips:
Offer water frequently, even if they say they’re not thirsty
Include high-water content foods like watermelon, cucumbers, or yoghurt
Keep their environment cool and shaded
Dehydration and Your Pets
Dogs, cats and other animals can suffer just as much—if not more—from dehydration.
Common signs in pets include:
Lethargy or weakness
Dry nose and gums
Panting or excessive drooling
Loss of appetite
Sunken eyes or skin that doesn't quickly spring back when gently pulled
How to Help Your Pets Stay Safe:
Ensure clean, fresh water is available at all times
Avoid walking dogs during the hottest parts of the day (usually 11am to 3pm)
Never leave animals in parked cars, even with the windows open
Provide shaded areas outdoors and consider using pet-safe cooling mats
Staying Safe in Hot Weather
To keep yourself and your loved ones safe this summer:
Drink water regularly throughout the day
Avoid alcohol and caffeine, which can dehydrate you further
Wear loose, light-coloured clothing
Stay indoors or in the shade during the hottest times
Dehydration is more than just being a bit parched, it can be dangerous and even life-threatening, particularly in hot weather. By taking a few simple precautions, you can ensure that everyone in your household—from toddlers to grandparents to pets—stays safe, healthy and cool this summer.
Stay hydrated, stay safe, and enjoy the sunshine responsibly.
