Electrolytes in hot weather: hydration during a heatwave

Change exposure before changing your drink

Follow local heat alerts and move, shorten or cancel exercise when conditions require it. Choose a cooler setting, breaks and reliable water access. Humid heat can make cooling harder: visible sweating does not prove that your body is losing enough heat.

Keep everyday water and food in the picture

A hot day without prolonged exercise does not automatically require electrolyte sticks. Drinks and meals already contribute fluid and minerals. With prolonged sweating, consider food, drinks and time exposed together rather than adopting a fixed dose for everyone.

Children, older adults and people with chronic conditions may need tailored advice. Do not override a prescribed fluid or salt restriction by adding sports drinks without discussing it with a clinician.

Use BreathersBliss within its directions

For an adult choosing it as part of a sports routine, the individual serving is easy to prepare: one stick in 300–500 ml cold water, one stick per day. Higher temperatures are not a reason to multiply servings.

Use drinking water and a clean bottle. Avoid leaving the prepared drink in prolonged direct sun and follow storage directions. A sports electrolyte product is not a substitute for medical oral rehydration solution.

Recognise when drinking is not enough

If dizziness, nausea or weakness develops in the heat, stop activity, move somewhere cool and have someone stay with you. Significant or persistent symptoms need medical assessment.

Confusion, loss of consciousness or seizures are an emergency. Call the local emergency number — 112 in Europe — begin cooling while waiting and follow the dispatcher’s advice. Do not give drinks to someone confused or unconscious. Heatstroke can occur even when a person is still sweating.
