We can keep going for a long time without food, but lack of water is not something we can tolerate for an extended period of time. Even insufficient intake of water which leads to dehydration has a negative effect on our body. In fact, prolonged dehydration causes internal organ damage and it is eventually lethal. Over a billion people do not have access to source of clean water and this is a major crisis that we don’t talk about often enough.

Key Takeaways:

• Water is always crucial. However, in cases of high perspiration, with the body under extreme duress, dehydration takes over and the need for water is greatly increased.
• Exercise makes water needs higher. So, do tropical climates. The more competition for water there is, between wildlife and human life, the more likely that water will be scarce.
• In areas where you can not turn on a tap to get gallons of water, or pump a pump and fill a bucket, you must trust to nature’s waterways and human and animal pollution for a clean drink.

“In most developed countries, accessing clean water is as simple as turning on a tap. People in these places pour gallons of it down the drain every day without a thought, as they brush their teeth, shower and flush the toilet. But around 1.1 billion people lack access to safe drinking water around the world, and a total of 2.7 billion find water difficult to access for at least one month of the year.”
