You do not need to have a medical diagnosis to have reasons to be more cautious around mold, water damage, or other indoor environmental problems.

Some people may need to be more careful because of their age, stage of life, health, or other personal factors. This does not mean that everyone in one of these groups will have a problem, and it does not automatically mean that they need to leave the home.

The goal of this lesson is simple: identify whether you—or someone in your household—may need a more cautious approach.

Expectant Mothers

Pregnancy is a time when many people choose to be more careful about things in their environment that could affect their health.

Pregnancy alone does not mean that someone must leave a home with a suspected mold problem. But it can be one more reason to take the situation seriously, avoid unnecessary exposure, and talk with a healthcare provider when there are concerns about water damage, mold, or indoor air quality.

Pregnant people should also avoid taking part in mold cleanup or remediation work.

Newborns, Infants, and Young Children

Babies and young children deserve extra consideration because their bodies and lungs are still developing.

They also breathe more air compared with their body size than adults do, which can increase their exposure to things in the air.

A baby or toddler may not be able to clearly tell you how the environment is affecting them. If there is significant water damage or mold in the home, having a newborn, infant, or young child may be another reason to take a more cautious approach.

Females After Puberty

After puberty, females are more likely than males to develop many autoimmune conditions. Hormones may be one reason their immune systems respond differently.

This does not mean that every female is automatically at higher risk from mold or a water-damaged building.

However, if a post-puberty female also has autoimmune problems, ongoing inflammation, significant symptoms, or other health concerns, that may be one more reason to use a cautious approach.

Older Adults

Being older does not automatically mean someone is high risk.

However, older adults may be more likely to have breathing problems, reduced immune function, or other health conditions that can make indoor environmental problems more important.

For older adults, overall health often matters more than age alone.

Don’t Forget Your Pets

Dogs, cats, and other indoor pets should also be part of the decision.

If a pet begins developing unexplained symptoms, contact your veterinarian.

They may spend nearly all of their time inside the home and often spend more time close to floors, carpets, dust, and other surfaces where particles can collect.

If a pet already has breathing problems, a weakened immune system, is very young, older, or medically fragile, it may deserve extra consideration when you are deciding whether to stay or leave.

Birds deserve special attention – their respiratory systems are very different from ours and can be very sensitive to airborne contaminants. Certain fungal diseases can also cause serious breathing problems in birds.
