A hot shower feels like the ultimate act of self-care — refreshing, relaxing, and necessary. But did you know that your daily shower could be a significant source of chemical exposure?

Chlorine is intentionally added to most municipal water supplies to disinfect and kill pathogens. However, it’s not selective — it can irritate your skin and eyes and may form harmful byproducts when heated, like trihalomethanes (THMs), some of which are carcinogenic. Over time, regular exposure adds up, especially for people with sensitive skin or respiratory issues.

Beyond chlorine, heavy metals such as lead and copper can leach into water from aging pipes and plumbing fixtures. And PFAS contamination in water supplies is becoming an increasing concern, adding yet another layer of invisible chemical exposure.

Remember that your skin is your largest organ. When you shower in hot, chlorinated water, your pores open and chemicals are more readily absorbed. Inhaling steam containing chlorine byproducts further increases exposure.

How can you reduce these risks?
– Install a certified shower filter that removes chlorine and heavy metals.
– Review your local water quality report to understand contaminants in your area.
– For those living in high-risk areas, consider filtering all household water.
