Water is an essential element for life and represents a fundamental component of our body. In adults, it accounts for about 65% of body weight, while in newborns this percentage can reach 75–80%. Proper hydration is crucial for the optimal functioning of the body and for maintaining overall health.

Benefits of water for the body

Adequate water intake offers numerous advantages:

✔ Lubrication of joints and muscles: About 70–75% of muscles are composed of water, which is essential for movement and for preventing cramps and muscle fatigue.

✔ Skin health: Proper hydration keeps the skin elastic, toned, and radiant, helping to reduce the formation of wrinkles and signs of aging.

✔ Regulation of body temperature: Water helps dissipate heat through sweating, preventing the body from overheating.

✔ Digestive support: Water facilitates digestion and helps prevent constipation by promoting intestinal transit.

✔ Cognitive function: Proper hydration is essential for maintaining concentration and improving memory.

How much water should we drink per day?

The amount of water needed varies depending on several factors, including age, gender, level of physical activity, and climatic conditions. However, a general recommendation is to consume about 2 liters of water per day. It is also important to remember that foods rich in water, such as fruits and vegetables, contribute to the body's overall hydration.

Tips for maintaining proper hydration

✔ Always carry a water bottle with you: Having water within reach will encourage you to drink more frequently.

✔ Set reminders: Use apps or phone alarms to remind yourself to drink regularly.

✔ Eat water-rich foods: Include fruits and vegetables with high water content in your daily diet, such as cucumbers, watermelon, and oranges.

✔ Drink a glass of water before meals: This can help both hydration and appetite control.

Why is hydration essential during training?

Water is a key element for sports performance. During training, the body loses fluids through sweat, which can lead to energy drops, muscle cramps, and early fatigue. Proper hydration helps keep body temperature under control, promotes nutrient transport to the muscles, and speeds up post-workout recovery.

How much and when to drink?

Water intake should be consistent throughout the day, but there are specific times when hydration is essential:

✔ Before training: Drinking 400–600 ml of water 30–60 minutes before physical activity helps prevent dehydration.

✔ During training: If the workout lasts less than an hour, small sips of water every 15–20 minutes are sufficient. For more intense and prolonged activities (over one hour), it is useful to supplement with electrolyte-rich drinks.

✔ After training: Replenishing lost fluids is essential for muscle recovery. Drinking 500–700 ml of water within an hour after training helps restore the body's fluid balance.

Water or sports drinks?

✔ Water: Perfect for moderate-intensity or short workouts.

✔ Isotonic drinks: Recommended for intense and prolonged sessions (such as marathons or endurance sports), as they also replenish minerals and carbohydrates.

✔ Water with lemon: An excellent natural alternative that supports rehydration with an extra supply of vitamins and minerals.

Signs of dehydration during training

If you experience these symptoms during training, you may be dehydrated:

✔ Dry mouth and intense thirst

✔ Early fatigue and reduced performance

✔ Muscle cramps

✔ Dizziness or headache

If you notice these signs, stop training and rehydrate immediately.

Conclusion

Water plays an irreplaceable role in maintaining our health and overall well-being. Ensuring that you drink an adequate amount of water every day is essential to support the body’s vital functions and prevent many dehydration-related issues. Adopting habits that promote proper hydration can lead to significant improvements in quality of life.
