The first truly warm days arrive subtly. In the morning, you leave your jacket at home, seek shade in the sun, and in the evening, you feel more tired than usual. For the body, however, the change in weather is a small restart.

As soon as it gets warmer, the body starts to work more with temperature, sweating, and water management. And that's when many people only focus on fluid intake, forgetting one important thing: along with sweat, the body also loses minerals and electrolytes.

Plain water is essential

Fluid intake should primarily be based on plain water. It helps to:

• replenish fluids,
• regulate body temperature,
• support blood circulation,
• and maintain normal bodily functions.

Water is usually sufficient during a calmer day:

• when working in an office,
• at home,
• in mild weather,
• or when you're not sweating excessively.

But in the heat, the situation changes.

What the body loses when sweating

Sweating is not just about losing water. Along with sweat, the body also loses minerals, such as:

• sodium,
• potassium,
• magnesium,
• chlorides.

Some of these act as electrolytes – substances important for fluid balance and the proper functioning of muscles and the nervous system.

Therefore, during hot days, sports, sauna, or prolonged sun exposure, it can make sense to replenish not only water but also a mineral drink.

When mineral water or a mineral drink might be suitable

Mineral water or a mineral drink is especially useful:

• during increased sweating,
• during sports,
• on trips,
• when working outdoors,
• in the sauna,
• during travel,
• or during the first truly hot days.

However, this does not mean drinking only mineral waters all day. Balance is important.

A simple rule could be:

Water as a base. Minerals as needed.

Thirst often comes too late

Many people wait until they are very thirsty. But the body often warns much earlier.

Early signs may include:

• fatigue,
• headache,
• difficulty concentrating,
• irritability,
• dry mouth,
• or a feeling of heaviness.

It is therefore good to drink continuously and not wait until the body starts to "scream".

Karlovy Vary Thermal Salt: a practical mineral drink for travel and home

One practical solution for replenishing minerals can be Karlovy Vary Thermal Salt. It allows you to prepare a mineral drink at home, at work, and while traveling – without carrying heavy bottles of mineral water.

It is suitable for example:

• in a handbag or backpack,
• for a trip,
• for work,
• for holidays,
• for sports,
• or as part of a home drinking cure.

It builds on the tradition of Karlovy Vary spa care, but in a more practical form for everyday life.

How to properly replenish minerals in the heat

A simple rule applies to mineral drinks:

more does not mean better.

It is important to:

• follow the recommended dosage,
• combine the mineral drink with your regular fluid intake,
• and not use the mineral drink as a replacement for all water throughout the day.

Caution is especially important for people with high blood pressure, kidney disease, heart conditions, or limited salt intake.

A small difference the body recognizes

The first hot days are a reminder that the body functions differently in the heat. It needs more fluids, greater regularity, and sometimes also minerals and electrolytes.

Plain water remains the base. A mineral drink can be a smart supplement at times when the body loses more than just water.

And often, very little is enough:
a glass of water, a few minerals, and a more regular fluid intake. 🤍
