Can You Drink Rainwater, and Should You?
Water is an essential component of nearly all forms of life. In fact, water comprises approximately 60% of the human body.
Your body loses water through a variety of natural biological processes like sweating and waste elimination.
Drinking plenty of water each day helps replace losses and keep your body healthy and functioning optimally.
Many people are accustomed to getting their drinking water from a tap, well, spring, river, or even a bottle.
But you may wonder whether it’s safe to drink rainwater.
This article reviews everything you need to know about drinking rainwater, plus a few tips to ensure your drinking water is safe to consume.
There is nothing inherently unsafe about or wrong with drinking rainwater, as long as it’s clean. In fact, many communities around the world depend on rainwater as their primary source of drinking water.
That said, not all rainwater is safe to drink.
Several physical and environmental factors can quickly turn fresh, clean rainwater into a potential health hazard. It can contain parasites, harmful bacteria, and viruses and has historically been linked to disease outbreaks (2Trusted Source).
Rainwater that falls in heavily polluted areas or comes into contact with contaminants, such as animal feces or heavy metals, may not be appropriate for human consumption (2Trusted Source).
Thus, it’s not advisable to start collecting and drinking rainwater unless you’re 100% certain it’s clean and safe for human consumption.
