On hot summer days, during sports, or while traveling, the body loses water much faster than we often realize. Dehydration can be the reason you feel tired, lack energy, or start to have a headache. How to recognize the symptoms of dehydration, what happens during it, and how to prevent it?

Water makes up most of our body

The human body is more than half water. This is essential for the functioning of all organs and natural processes in the body.

It helps regulate body temperature, participates in nutrient transport, removes waste products, and is also important for the proper functioning of muscles and the nervous system.

When water begins to decrease, the body quickly recognizes it.

How does dehydration occur?

Dehydration occurs when the body loses more fluids than it takes in.

The most common causes are:

• high outdoor temperature,
• intense sweating,
• sports activity,
• sun exposure,
• fever,
• diarrhea or vomiting,
• insufficient fluid intake.

In summer, individual factors often combine. A morning trip, an afternoon at the swimming pool, and an evening get-together with friends can mean that the body loses significantly more fluids than you replenish during the day.

How to recognize the first signs of dehydration?

The body asks for water relatively quickly.

The first signs of dehydration include:

• thirst,
• dry mouth,
• fatigue,
• headache,
• darker urine,
• decreased performance,
• poorer concentration,
• feeling of weakness.

If you do not replenish fluids, the difficulties may gradually worsen.

Water alone is not enough

When sweating, the body does not only lose water.

Along with it, mineral substances are also lost, which participate in a number of natural functions of the organism.

Therefore, during hot days, it is important to think not only about sufficient fluid intake, but also about their regular replenishment and a balanced diet.

Mineral substances, also known as electrolytes, help maintain the correct fluid balance in the body and are especially important during increased sweating.

Who is most at risk of dehydration?

The highest risk of dehydration is especially for:

• athletes,
• people working outdoors,
• children,
• seniors,
• tourists,
• people spending holidays by the sea,
• visitors to festivals and summer events.

It is precisely for them that the need for fluids is significantly higher during the summer.
