Hot weather, physical activity, irregular eating, illnesses such as vomiting and diarrhea, and alcohol consumption lead to even more fluid loss, which means our body becomes dehydrated.
In a normal human body, water, electrolytes (K+1, Mg+2, Ca+2, Na+1) nutrient factors, and cells are present in certain amounts to sustain vital functions. Dehydration is a condition that occurs when the body does not have enough fluid to function optimally. Our body consumes about two liters of water daily through breathing, sweating, and the excretory system.
This fluid loss increases during physical activity; we can lose more than two liters of water per hour during strenuous exercise, and remember, what we lose is not just water. We also lose valuable electrolytes that our body needs to function at its best(K+1, Mg+2, Ca+2, Na+1).[/mpc_textblock]


From this point on, it means you are dehydrated. However, for an athlete, this may be a bit late as it likely has already started to affect performance.
The best avoidance technique for athletes in this situation is to continuously monitor urine output in terms of volume and color; both infrequent urination and dark-colored urine are signs of the onset of a dehydrated state and, in most cases, the first obvious sign of thirst.[/mpc_textblock]
