The main building blocks of cells, tissues, and organs in the human body require water to ensure a healthy metabolic cycle.
We all know that we must stay hydrated. If we accidentally forget, there’s no panic, the brain function controlling our “thirst” kicks in to remind us. But do we really know how to identify the symptoms leading up to dehydration, as well as the dangers?
When an adult’s water deficit exceeds 8% of their body weight, vital prognosis is engaged. But before reaching this extreme state, dehydration is accompanied by other harmful alterations.
Impairment of physical performance, starting from a water loss of even 1% of one’s total weight.
When dehydrated, the volume of water in blood plasma decreases, making blood thicker, and requiring the heart to work harder to propel it into vessels. As blood circulation in the small capillaries are reduced (because of the thicker blood), muscles are affected as oxygen and nutrient levels are reduced, as well as our body’s capacity to eliminate toxins.
Alterations in cognitive performance and mood exist with water deficits starting from 1.4-2% (relative to our body weight).
Beyond simply allowing many vital bodily functions, good hydration also optimizes brain functionality. Not only does the brain function at the highest level when well hydrated, but the intellectual, emotional, and sensory elements of our body can also reach its maximum capacity. Our brain is immersed in cerebrospinal fluid. This liquid has a very high water content, provides nutrients and eliminates toxins produced by cellular neurons, and is the area of the brain that tells us that “we’re thirsty”, according to researchers. When our body lacks water, the amount of cerebrospinal fluid also decreases, which results in the deterioration in cognitive abilities (including confusion, decreased concentration and alertness), as well as our mood in general (tiredness, decreased serenity and happiness). A well hydrated body (and brain) therefore allows for a broader and larger capacity for comprehension, memorization, physical performance, as well as overall wellbeing and happiness.
When children drink 200-650ml of water, there is an immediate decrease in thirst, and improvement in happiness, memory, and motor skills. Also, recently, a study carried out by 447 undergraduate students saw better exam results amongst the students who brought water to the exam.
Alteration of cardiovascular functions, including an increase in heart rate and decrease in blood pressure, starting from a water deficit of 2% (relative to body weight)
When one is dehydrated, the volume of overall blood is decreased, forcing the heart to beat faster in order to maintain regular blood pressure.
Significant probability for a headache, starting from a water deficit of 4% (relative to body weight)
According to several studies, those who are dehydrated are very prone to headaches. In addition, an increase in water consumption (by at least 0.8 liters per day) has reduced headaches and increased overall quality of life for patients who have recurrent migraines.
Adequate hydration reduces a variety of common diseases such as constipation, urinary tract infections, exercise-induced asthma, chronic kidney disease, etc.
That’s not all! During intense exercise, hydration cools the body; if the body isn’t cooled, thermal shocks (heat strokes) can occur. One must continue to consume lots of water, hours after physical activity, as our bodies will be working hard to recover.
If we are thirsty or if our bodies are dehydrated, even moderately, deteriorations in health, and cognitive and physical functions will be instantaneous and evident. This is why it is best to drink water before you are even thirsty.
Despite water’s crucial roles, it isn’t prioritized, nor judiciously mentioned in many nutritional articles and recommendations. However, the importance of what, and how much we drink, is just as important of what, and how much we eat. At Bello, we recognize water to be a vital nutrient, and we are committed to developing an innovative water purifier that is capable of providing the best water for your body. We don’t mess with health!
