The human body is dependent on water for survival, and far more besides. Our bodies consist of around 70% water, which can be found in every single cell in the body, and for good reason, as water is needed for most of the functions of the body.

If one does not drink sufficient water on a regular basis, it can lead to dehydration, which will prevent your body from functioning optimally.

The body loses water in various ways throughout the day, and not replacing this lost water for a few hours will lead to mild dehydration (3% to 5% loss); if you go longer than a few hours without replacing lost water it will result in moderate dehydration (6% to 9% loss) and eventually to severe dehydration (10% or more loss).

While losing less than 10% water may not seem like such a lot, and you may think that it cannot possibly do that much damage, it can be critical:

Mild dehydration can easily occur due to excess urination or even normal perspiration on a warm day and generally occurs without us even realising it. Mild dehydration can lead to a dry mouth, thirst, dry nose and lips, and darker urine. Thirst is your brain telling you that you need to drink water; do not ignore this message from your body.

Moderate Dehydration can occur due to low potassium and sodium levels in the body, which can affect your heartbeat, causing your heart to have to work harder to pump oxygen and blood through your body. Moderate dehydration can result in dry mouth, lips and nose; dry skin; headaches; fatigue and lethargy; extreme thirst; low blood pressure; blue lips; confusion; constipation; decreased urine output; rapid breathing; dizziness and light-headedness; a rapid, weak pulse; muscle-cramping, and more.

Severe Dehydration is extremely serious and requires medical attention. severe dehydration can result in kidney stones; muscle -damage and cholesterol problems; a weak pulse; bloody or black stools; dry skin; feelings of disorientation; seizures; inability to keep down fluids; inability to urinate; inability to cry; irritability; low blood pressure; diarrhoea; vomiting or a fever; coma and eventual death.

Drink water regularly in order to keep your body well-hydrated, healthy and in perfect working order. If you do not like tap water then invest in a water cooler to ensure that your drinking water is always chilled and pollutant-free.
