How much water should you drink when temperatures exceed 30 degrees: Is water alone enough?

When the thermometer crosses 30 degrees, most people instinctively reach for a glass of cold water. And for good reason. During the summer heat, the body loses more fluids than usual, primarily through sweating, and even mild dehydration can cause fatigue, headaches, dizziness, and decreased concentration.

However, one of the most common questions during the summer is: how much water do we really need and does spending time at the beach further increase the body's need for fluids?

There is no one rule for everyone.

The famous recommendation of eight glasses of water a day can serve as a guideline, but fluid needs vary from person to person. They are influenced by body mass, age, health status, physical activity, and weather conditions.

During days with temperatures above 30 degrees, most adults need between two and three liters of fluid per day, while those who spend time outdoors, play sports, or do physically demanding jobs may have needs even greater than that.

Experts advise not to wait until you feel thirsty, as this is already a sign that your body has started to lose the necessary amount of water. Why do we dehydrate faster on the beach?

Being at the beach increases the risk of dehydration for several reasons.

First of all, high temperatures and direct sunlight increase sweating. An additional problem is that the sea breeze often creates a feeling of comfort, so many people don't notice how much fluid they are losing.

Swimming can also trick the body. Even though we are in the water, the body still sweats, especially during swimming or beach activities. That is why it is not uncommon for people to spend several hours in the sun and drink significantly less water than they need.

That's why doctors recommend drinking water regularly, in smaller quantities, while at the beach, and not only when you feel very thirsty. Is water alone enough?

Water is the best choice for hydration, but it's not the only one.

During extreme heat, the body loses not only fluids through sweating, but also electrolytes, primarily sodium, potassium, and magnesium. Therefore, the following can also contribute to hydration:

- mineral water, - unsweetened herbal or fruit teas, - lemonade without a lot of sugar, - milk and yogurt, - fruits rich in water such as watermelon, cantaloupe, peaches, oranges and strawberries.

Homemade drinks with a little salt and lemon juice are also a good choice, especially after prolonged exposure to the sun or physical activity. What about carbonated drinks?

Carbonated drinks often have a refreshing effect, especially when well chilled. However, most industrial carbonated drinks contain large amounts of sugar.

High sugar intake can temporarily increase thirst, and excessive consumption contributes to the intake of "empty calories." In addition, carbonated drinks cause bloating and discomfort in some people, which makes it even harder to tolerate the heat.

Carbonated mineral water may be an acceptable choice for refreshment, but sweetened juices should not be your primary source of fluids during the summer. Alcohol and heat are not a good combination

Summer, the beach and a cold beer seem like an ideal combination to many, but experts warn that alcohol increases the risk of dehydration.

Alcohol is a diuretic, meaning it encourages the body to excrete more fluid through urine. At the same time, it can reduce the feeling of thirst and make it harder to assess your own condition.

At high temperatures, this can lead to faster exhaustion of the body, a drop in blood pressure, dizziness and even collapse.

Therefore, it is recommended to drink a glass of water with every alcoholic drink, and to minimize alcohol consumption during the hottest part of the day. How to recognize that the body lacks water?

The first signs of dehydration are often dry mouth, dark urine, fatigue and headache. Later, dizziness, rapid heartbeat, muscle cramps and a feeling of weakness may occur.

One of the simplest indicators is the color of your urine - a light color generally indicates good hydration, while a darker color may be a signal that the body needs more fluids.

When temperatures exceed 30 degrees, the need for fluids increases significantly, and a few hours spent on the beach can increase water and electrolyte loss more than we think. Water remains the best ally during summer days, but fruits, mineral water, teas, and other drinks without much sugar also contribute to hydration.

On the other hand, sugary sodas and alcohol can create a false sense of refreshment, while actually making it harder to maintain fluid balance in the body. That's why one of the most important rules of summer is simple – drink water before you feel thirsty.
