Do you have any questions?
Heat Shock is a UK wellness brand built for sauna lovers who take recovery seriously. Our hydration supplements and insulated bottles are designed to keep you cool, balanced, and thriving in the heat. Sauna sessions can boost your heart health and longevity—but without proper hydration, you lose up to 2 litres of fluid. We help you rehydrate smartly, so you get all the benefits without the burnout.
Sauna’s great for blood flow and muscle recovery—but the sweat you lose also drains key minerals like sodium and potassium. Our formulas are packed with science-backed electrolytes to reduce cramping, fight fatigue, and rebalance your nervous system. Pair that with icy-cold hydration in a heat-safe bottle, and you’ll bounce back faster—mentally and physically. Sauna UK
Expect better mood, sharper focus, and more all-day energy. Sauna helps lower stress hormones and boost dopamine, while our hydration solutions stop the crashes that come from dehydration. With stable electrolyte levels, you support metabolism, reduce inflammation, and feel more switched on in and out of the heat.
Yes. Sauna boosts heat shock proteins (HSPs), which protect your cells and help you age better. Regular sessions can cut all-cause mortality risk by up to 40%—but only if your body stays balanced. We make sure your hydration and minerals are on point, so you get all the long-term health benefits without side effects.
Overheating. Dehydration. Dizzy spells. We hear you. Sauna UK can feel intense—but it doesn’t have to be risky. Our electrolyte blends and insulated bottles are designed to keep your body cool and stable, so you stay safe while enjoying the detox, endorphins, and deep relaxation.
Inside the sauna, regular water just isn’t enough. You’re sweating out sodium, potassium, and magnesium—vital for muscle function, blood flow, and recovery. Our formulas replace what’s lost with precision. Plus, our bottles are built to keep drinks cold and toxin-free, even in 90°C heat.
