In the quest to avoid the 2019 novel coronavirus, we’re going through bottles of soap and tubs of disinfectant wipes faster than some stores can restock them.
Along the way, there’s been some speculation on social media that all the hand-washing and disinfecting we’re doing in the name of keeping coronavirus away could be weakening our immune system
Are there downfalls to being squeaky clean?
Allergist and immunologist James Fernandez, MD, Ph.D., says there’s no scientific evidence to suggest that temporarily stepping up your cleaning game is dangerous to your immune health.
“For adults, in this time frame we’re talking about and the hygiene measures that we’re taking, I don’t think there’s a lot of clinical risk to our immune system,” he says.

Hygiene aside, there are many factors that play into how well-equipped your immune system is to fight infections. Some of those things are out of your control, such as age and genetics. But there are several things you can do to keep your defenses strong, including:
- Find ways to cope with stress. Stress causes your body to make a hormone called cortisol. Over time, cortisol can lead to inflammation and reduce your body’s ability to fight infections.
- Fuel-up smartly. A well-rounded diet with ample amounts of fiber and healthy fats help keep inflammation at bay.
- Keep moving. Regular exercise helps keep your immune system running smoothly.
- Get your Zzzs. The average adult needs about seven to nine hours of sleep a night.
Avoid harmful substances. Smoking and excessive drinking can weaken your immune system.
