Stress itself is caused when we have to deal with something we don't feel we are physically or emotionally able to handle and an example of a stressor could be a big test, or moving to a new city.
How this comes into play is when we have to deal with one of these stressors, we go through a stress response commonly known as fight or flight. You act differently depending on the stressor, but you analyize the situation and then your body and mind decide if you can stay and deal with the threat or if you should leave to avoid it. If your body decides you should choose the fight method you get a big burst of energy to fight the potential threat, if flight is chosen you will try to find the easiest and safest mode of escape.
Keep in mind that this is a very primal thing and is triggered by tons of stuff, but most of the time it is a false alarm; an example could be the test anxiety some people feel which is not an actual physical threat, but sometimes yur mind will treat it as one.

Lack of clean water is able to complicate health. This could easily cause dehydration in children and adults. If someone is dehydrated, they won't be able to function properly and if they stay like this for long, this can cause a risk of death. Lack of clean water can easily turn into hygiene problems because the child wouldn't have a way to clean themselves or even do something as simple as washing their hands. This can transfer many bacteria only making the children catch illnesses. This, therefore, would prevent them from learning. This also goes for teachers because if the teachers do not have proper hygiene, they won't be able to teach. Once again this would affect children as well because children wouldn't have anyone to learn information. This would result in a bad education.
