What impact does poor hygiene have on health?

When people are denied access to clean water and decent toilets their hygiene and health suffer.

Poor hygiene means children get sick and miss school, adults can't work to support their families and patients are at risk in health centres. Whole communities miss out on opportunities to improve their lives.

In fact, many get no chance at life at all. Every two minutes a child under five dies from diarrhoeal diseases caused by lack of safe water, sanitation and poor hygiene practices.

So when a community gets clean water and decent toilets for the first time, they also have the power to change their hygiene habits. They can keep themselves and their environment clean, stay healthy and stop diseases spreading, and live dignified lives.

What do we mean when we talk about hygiene?

Hygiene can be hard to define as it covers so many behaviours, from personal hygiene like handwashing, food hygiene and menstrual hygiene, to the clean use of toilets and the safe use of water. Some groups of people are also more affected by poor hygiene – especially people with disabilities, young girls, women and babies.


Whether it's after going to the toilet, before eating or when you're preparing a meal, washing your hands is one of the easiest ways to prevent the spread of disease.

15 October is Global Handwashing Day - a chance for everyone to pledge their support for universal access to clean water and soap for handwashing.

Why do we talk to people about hygiene?

If you've never had a tap or running water before, getting into the habit of washing might not be as easy as it sounds. So when we bring clean water to a community, we also show people how important keeping clean is.

How WaterAid promotes good hygiene

We know through experience that there's no one-size-fits-all approach, and simply explaining the importance of good hygiene isn't enough to make lasting change happen. That's why we listen to people to understand what really drives them to take up new hygiene habits. 

On 15 October join us in supporting the #CleanHandsForAll campaign and show you agree that no one should have their access denied to handwashing.
