Even though everyone knows how essential drinking water is, dehydration remains a silent enemy in the world of running. The need to drink is like that dashboard light you ignore until everything shuts down: by the time you notice it, it’s often too late.
Why water is your best ally
Water makes up about 60% of your body weight and is essential for regulating temperature, eliminating waste, keeping skin elastic, and circulating nutrients. Losing even just 1-2% of water can lead to mental and physical fatigue.
The signals your body sends you
Mild symptoms
Imagine you’re the conductor of your body’s orchestra. If the orchestra starts playing out of tune, it’s time to check if all the instruments are in tune. Mild dehydration manifests in subtle ways:
- Thirst: the first warning bell, though often, when it rings, it’s already too late.
- Dark urine: if it looks like concentrated orange juice, it’s time to drink.
- Dry, sticky mouth, chapped lips.
- Unusual fatigue even after adequate rest.
- Headache, throbbing like a runaway metronome.
- Dizziness when you stand up too quickly.
Severe symptoms
When the situation worsens, the orchestra starts playing completely out of tune and out of time. This is moderate or severe dehydration, which you can identify if you have these symptoms:
- Decreased or absent sweating: this means the body is conserving every drop.
- Skin losing elasticity: if you pinch it and it doesn’t spring back immediately, it’s a bad sign.
- Accelerated heart rate: the heart is working overtime to pump thicker blood (cardiac strain).
- Muscle cramps: you start feeling cramps more frequently.
- Mental confusion, irritability, difficulty concentrating.
When to call a doctor: if severe thirst, confusion, palpitations, almost absent or dark urine, or continuous vomiting appear – don’t hesitate: call a doctor yourself or ask someone to call one for you.
Remedies
Before you start
Don’t wait until you’re thirsty to drink. Two to three hours before your workout, drink half a liter of water. An hour before, another glass. It’s like preparing your car for a long trip: it’s better to fill up before you hit the road.
During the run
For activities lasting over an hour, water alone isn’t enough. Sweat also depletes electrolytes like sodium, potassium, and magnesium. That’s why, in addition to gradual hydration with small, constant sips (better than emptying a whole bottle at once), it’s advisable to add electrolytes with oral rehydration solutions, especially during hot weather or intense workouts.
After your workout: smart recovery
Recovery is a subtle art. Continue to drink water, but if you’ve sweated a lot, replenish electrolytes and carbohydrates. Make yourself a fruit smoothie, for example, with bananas, which are rich in electrolytes, or a glass of chocolate milk. These can work wonders due to their balance of carbohydrates and and protein. To get an idea of how much fluid you lose during your workout, use the simple weight trick: weigh yourself before and after. Every kilogram lost corresponds to approximately one liter of fluids to replenish.
Hydrating foods
Fruits and vegetables like watermelon, cucumbers, oranges, and yogurt contain a lot of water and natural salts. You can find ready-made rehydration solutions at the pharmacy, or you can prepare a homemade one: dissolve 1 teaspoon of salt and 6-8 teaspoons of sugar in one liter of water.
When to see a doctor
If symptoms persist, worsen, or confusion, fainting, or vomiting with blood appear, intravenous rehydration and hospital supervision are needed.
Awareness makes the difference
Hydration isn’t just a list of symptoms and remedies; it’s constant awareness. It’s learning to listen to your body’s whispers before they turn into shouts. Recognizing your body’s state is a form of attentiveness: if you notice something changing – thirst, fatigue, dark urine – intervene immediately with water and electrolytes.
Proper hydration means continuing to run with a steady pace, without slowing down. It’s a continuous dialogue with yourself, a daily commitment that allows you to perform at your best in every workout. Your body will thank you, and you’ll be able to keep chasing every goal you’ve set for yourself.
