It’s no secret that water heaters are loud and loud and annoying.

But according to the Centers for Disease Control and Prevention (CDC), some of those noises are a result of water heat-related issues.

The CDC reports that water-related noise can cause problems with the immune system, nervous system, brain, heart and lung.

In fact, it has found that a water heater can cause hearing loss in one in five people, even though water heat has a much lower concentration of lead in it than a conventional water heater.

The same CDC study found that water hot water is also linked to the development of asthma and heart disease.

And while most water heat is safe to use in hot climates, the CDC warns against the misuse of the water heater by children, pregnant women and people with allergies and asthma.

“We don’t recommend water heat in the home unless you have a well-controlled asthma, asthma attack, or a chronic health condition,” said CDC spokesperson Jennifer Peeples.

“These people are more likely to be exposed to harmful substances.”

The CDC also recommends keeping your water heat on low and cool during the summer months.
