“Water is the lifeblood of all life.” This quote from explorer Jacques-Yves Cousteau sums up the vital importance of hydration for our bodies. As heat waves become more frequent, it is essential to know how much water our bodies actually need to stay healthy. In this post, we will highlight the importance of hydration during heat waves and the precautions to take to avoid the risks associated with dehydration.

The Importance of Hydration in Hot Weather
Recently, several regions of the world have experienced higher than usual temperatures in the summer. With temperatures increasing each year, it has become more important than ever to pay more attention to our bodies, apply sunscreen and drink enough water to avoid dehydration.
Hydration is fundamental to health, especially during intense heat. It plays a crucial role in several essential aspects of well-being. First, water is essential to regulate body temperature through sweating. When temperatures rise, the body sweats to cool the skin; without adequate hydration, this process is disrupted, increasing the risk of heat stroke.
In addition, adequate hydration prevents serious disorders such as exhaustion and muscle cramps. These problems occur when the body loses more water and mineral salts than it receives, thus disrupting the water and electrolyte balance.
Proper hydration is also essential for optimal organ function, failing which can lead to decreased blood volume, increased concentration of toxins and impaired kidney function, among other adverse effects.
In hot weather, hydration also improves physical performance by maintaining endurance, strength and coordination, which reduces fatigue and helps you stay active.
Finally, water is crucial for maintaining fluid and electrolyte balance in the body. During extreme heat, the body loses a lot of sodium and potassium through sweat, and proper hydration helps replenish these essential elements.
Those How Much Water Should You Drink During a Heatwave?
The NHS (National Health Service) generally recommends drinking between six and eight glasses of water a day, but this amount can change in summer and extreme heat. However, the final advice from the US National Academies of Sciences, Engineering and Medicine is that the adequate amount of daily fluid is 15.5 cups (3.7 litres) per day for men and 11.5 cups (2.7 litres) per day for women.
GP Dr Angela Ray says: “In hot weather, and especially if we are exercising, our need for water increases. On a hot day we should drink up to three litres of water, but it is important to spread this out throughout the day and not drink too much at once.”
Signs of Dehydration to Watch For
The U.S. Centers for Disease Control and Prevention (CDC) recommends not waiting until you’re thirsty to drink water, because by then you’re already dehydrated.
Thirst, dark-colored urine, and strong odor are early signs that you may be dehydrated. Other symptoms include fatigue, dizziness, or dry mouth.
While it’s important to know if you’re drinking enough water, the Mayo Clinic says that if a person rarely feels thirsty and their urine is clear or pale yellow, there’s likely nothing wrong with their water intake. The organization recommends drinking 0.2 liters of water every 15 to 20 minutes, and 0.7 to 0.9 liters of water per hour if you’re exposed to heat all the time. However, if you’re drinking more than 1.4 liters of water per hour, there’s a risk of overhydration, which can lead to low blood salt levels.
Another rule is that the more a person sweats, the more water he or she should drink..
Foods that Help Hydrate
According to The Independent, if you want to hydrate your body but have trouble drinking water, you can make up for some of your daily fluid intake by eating water-rich fruits and vegetables, such as cucumber, tomato, celery, watermelon and zucchini. Strawberries, lettuce, peaches and yogurt are also recommended.
Just because you’re no longer active outdoors doesn’t mean you can stop drinking water. It can take several hours to drink enough water to completely replace what your body has lost through sweat. So it’s recommended that you continue to drink throughout the day to minimize the potential effects of dehydration.
