Dehydration is a real danger in heat, hard exertion, and especially during illness with vomiting or diarrhoea — where it can become serious quickly, particularly in children and older people. Plain water doesn't replace the lost salts your body needs to actually hold onto that water. Rehydration salts restore the electrolyte balance, so you recover far faster and feel human again sooner.
They're light, keep for ages, and address a genuine medical need that water alone can't. A few sachets in a first-aid or travel kit is cheap insurance against the flattening effects of a stomach bug or a scorching day's exertion.
Use them when you've lost a lot of fluid and salts — after heavy sweating on a hot or strenuous day, or during a bout of sickness or diarrhoea. Dissolve in clean water and sip steadily. For serious or prolonged illness, especially in the very young or old, seek medical advice as well.
Look for sodium, potassium and glucose in sensible proportions — that's what rehydrates effectively, not just flavoured water.
Pre-measured sachets or tablets are easy to carry, keep well, and take the guesswork out of mixing the right dose.
Dry salts store for a long time, so they're ready in a kit for years — check and rotate at the expiry date.
Water alone doesn't replace lost salts and can even dilute them further. Rehydration salts restore the balance your body needs to recover.
More is not better — an over-concentrated mix can worsen things. Follow the dosing on the sachet with the stated volume of clean water.
Balanced electrolyte hydration tablets that replace the salts lost to sweat, heat and illness, helping you rehydrate faster than water alone.
A well-known pharmacy oral rehydration salt that replaces the water and electrolytes lost to diarrhoea, vomiting or heavy sweating. Worth keeping in a first-aid kit or grab bag because dehydration is a real risk during illness, heatwaves or when you are rationing questionable water. Each sachet dissolves in fresh water to make a measured drink.
A ten-pack of 3M's valved FFP2 disposable respirators, the kind you want on hand for dusty clean-up after a flood, storm damage or DIY. The exhalation valve makes them easier to breathe through during longer jobs, and FFP2 filtering handles fine dust and non-oily particles. Not a substitute for FFP3 where finer protection is needed, but a sensible general-purpose layer.
A genuine FFP3 disposable respirator from 3M, the highest particulate filtering class for dust, mould, fine debris and other airborne hazards during clean-up or repairs. The Cool Flow valve cuts heat and moisture build-up so it stays wearable on longer jobs. It is a fit-dependent single-use item, not a substitute for a reusable half-mask if you need protection daily.
A pack of ten disposable FFP2 respirators from 3M, the reference name in respiratory protection. The mask to reach for when clearing dust, mould or debris after a flood or storm, or filtering fine particles during any dirty clean-up.
Mains-powered optical smoke alarms with a rechargeable back-up cell, from Aico — the brand fitted as standard in a large share of UK homes and social housing. Unlike battery-only units these wire into the ring and can be interlinked, so one triggered alarm sounds them all. This is the fit-and-forget option for anyone wanting proper hard-wired cover rather than relying on a single stand-alone detector.
CE-certified valved FFP3 respirators that filter ~99% of fine airborne particles — dust, smoke and debris — with an exhalation valve and adjustable seal for comfortable, protective wear.
A reusable half-mask respirator with A1P2 filters, so it handles both dust and organic-vapour fumes rather than particles alone. Reach for it during dusty clean-ups, mould removal, spray painting or working with solvents. The replaceable-filter design makes it cheaper over time than getting through boxes of disposables.
