So, What Happens When You’re Dehydrated

Water is vital for life. It it is essential for some bodily functions and is the reason for 50-70 percent of the body’s weight. Any deficit in standard body water – through exercise, sickness, dehydration or heat stress – can make us feel shitty. First we feel thirsty and fatigued, and may develop a mild headache. This eventually leads to grumpiness, and psychological and physical inadequacy.

So, What Happens When You're DehydratedWe continuously shed water via urine, our breath, feces and skin. Many healthy individuals manage their body’s water level remarkably effectively via eating and drinking, and so are guided by hunger and thirst. But this can be more challenging for babies, the sick, seniors, athletes, and those with strenuous physical careers, specifically in the heat.

What happens when you’re dehydrated?

So, What Happens When You're DehydratedFrom the moment you’re feeling thirsty your system is already dehydrated; our desire mechanism lags behind our real level of hydration.

Investigation demonstrates as little as 1 percent contamination badly influences your storage, awareness, temper and motor control. Knowledge in humans is contradictory and lacking, nonetheless it appears that brain tissue fluid decreases with dehydration, briefly affecting cell function and minimizing brain volume.

When you ‘shed’ body water without replacing it, your blood becomes more concentrated and at some point, this triggers your kidneys to retain water. The end result: you urinate less.

The thicker your body and more concentrated your blood becomes, the harder it is for your heart to compensate by improving heart rate to maintain blood pressure.

So, What Happens When You're DehydratedWhenever your dehydrated body is’ pushed’ – for example when exercising or faced with heat stress – the danger of fatigue or fall increases. This could cause you to faint, when you stand up too quickly. Less water also hinders the body’s attempts at regulating heat, which can cause hyperthermia (a body temperature greatly above normal).

At a cellular level, ‘shrinkage’ happens as water is successfully borrowed to maintain additional stores, like the blood. The brain senses this and causes a heightened feeling of thirst.
