Podcast Summary: Chasing Life with Dr. Sanjay Gupta

Episode: Here’s Why You Should Take Your Shoes off at the Door...Please
Date: March 10, 2026
Host: Dr. Sanjay Gupta
Main Guest: Dr. Gail Saltz (Featured from previous episode)

Overview

This episode explores two central themes.
First, Dr. Sanjay Gupta gives an in-depth answer to a frequently asked question: Should you take your shoes off at the door, especially for health reasons?
Second, the episode (in its latter half) revisits an earlier interview with psychiatrist Dr. Gail Saltz, focusing on strategies to prioritize mental well-being—especially for families—while staying informed during times of distressing global events.

Should You Wear Shoes Inside the Home? (01:08–04:48)

Key Discussion Points

Cultural Customs:
Dr. Gupta describes how removing shoes at the door is a time-honored tradition in many cultures (Japan, Korea, China, Muslim countries, Northern and Eastern Europe). Reasons range from spiritual and religious respect, simple comfort, protection of floors, or cultural custom.
Hygiene and Cleanliness:
- Removing shoes is far more hygienic. Shoes track in a wide array of contaminants, including:
  - Harmful bacteria and viruses (even drug-resistant strains)
  - Pesticides, herbicides, heavy metals
  - Chemicals from lawns, dry cleaners, work sites, asphalt
  - Animal waste
- Reference to a University of Arizona study (2008):
  
  “They found after two weeks of wearing shoes, 10 participants were found to carry 421,000 units of bacteria per square centimeter.”
  — Dr. Sanjay Gupta [02:23]
Impact on Air Quality:
Tracking in contaminants doesn’t just affect floors; it affects household air:

“People spend up to 90% of their time indoors...about 30% of the matter that builds up in an indoor space is imported from the outside.”
— Dr. Sanjay Gupta [03:18]
Risk Assessment:
Dr. Gupta notes that for a healthy adult, the odds of getting sick directly from shoe-borne hazards are relatively low, and that other sources of germs are often more significant (kitchen sponges, smartphones, pets).
Exceptions & Recommendations:
- Removing shoes is especially wise if:
  - You have young children crawling around
  - You or a housemate is immunocompromised
  - You want less debris in your home
  - Visiting a “no shoes” home as a guest
- In his household, removing shoes is the norm, though not always mandatory now that his kids are older.

Notable Quote

“It’s probably worth just kicking off your shoes before entering the home. We do that in our household. It is pretty natural.”
— Dr. Sanjay Gupta [04:10]

Conversation with Dr. Gail Saltz (07:27–14:26)

Key Strategies for Parents & Children

Initiating Conversations with Kids:
- If children are over 10, proactively start discussions about what they’ve heard, inviting their questions.
- Be honest, but not graphic; don't be afraid to say “I don’t know.”
“You want to be the trusted source and you want them to be able to talk to you about it.”
— Dr. Gail Saltz [08:14]
- Advise kids to limit visual news intake to protect mental health.
- With younger children (under 10), listen for cues—don’t force the issue unless they’re already aware.
Coping Mechanisms:
Both kids and adults can benefit from channeling anxiety into helping others.

“Helping for adults and kids is a great defense mechanism. It really...helps people to feel better when they are feeling scared and helpless.”
— Dr. Gail Saltz [09:53]

Balancing Staying Informed and Mental Wellness

Personal Practices:
- Limit news exposure, especially visuals; schedule news check-ins, avoid continuous social media scrolling.
- Recognize the body’s role in anxiety (the physiologic response often precedes anxious thought).

“It always feels to us like we thought a thought and then our body had this response. But often it’s the other way around.”
— Dr. Gail Saltz [10:53]

Relaxation Techniques

Paced Deep Breathing:
- Inhale with chest expanding to a slow count of five; exhale longer (count of seven) through the mouth.
- Longer exhale helps slow the heart rate and manage anxiety.
- Practice for 5–10 minutes for maximal benefit.
“That long, extra exhale is what slows your heart rate...and that helps bring the anxiety down.”
— Dr. Gail Saltz [13:10]
Progressive Muscle Relaxation:
- Sequentially tense and relax muscle groups (feet, legs, arms, shoulders, neck, face), counting to five for each.
- Promotes full-body relaxation.

Notable Quotes & Memorable Moments

On Shoes and Germs:

“Hands down, not wearing shoes in your living space is much cleaner, much more hygienic.”
— Dr. Sanjay Gupta [01:58]
On Kids and News:

“If your child is over 10...you want to open up this conversation because you want to be the trusted source.”
— Dr. Gail Saltz [08:09]
On Managing the News:

“I will limit what I’m looking at...I might look at my headline in the morning. I might look again in the afternoon.... And I’ll read as opposed to looking at images.”
— Dr. Gail Saltz [10:29]

Welcome back to paging Dr. Gupta. So, shoes on or off in the home, especially when it comes to thinking about hygiene. First of all, let me say this. In some cultures, it is just customary to take off your shoes when you enter an indoor space. Japan, Korea, China, some Muslim countries as well as countries in Northern and Eastern Europe. I was just in Denmark. People take their shoes off when they enter the home. The reasons for this can vary greatly. Some of it is to honor religious and spiritual traditions. Sometimes it's just a sign of respect, a cultural norm or a custom to protect the floors. Simple as that. For comfort, you know, you're signifying that you're home now and you can relax and unwind and, and then yes, for hygiene and cleanliness. And when it comes to this last point, it's not even close. Hands down, not wearing shoes in your living space is much cleaner, much more hygienic. Look, the soles of your shoes, they track in a wide range of contaminants. Some of them potentially harmful bacteria and viruses, including drug resistant pathogens. Especially for example, at the shoe wearer like me when was visiting a hospital. Now, there was this one famous or perhaps infamous experiment conducted in 2008. It was done by this microbiologist at the University of Arizona. And they found after two weeks of wearing shoes, 10 participants were found to carry 421,000 units of bacteria per square centimeter. That's a problem. You also have things like pesticides and herbicides and other chemicals. From lawns or dry cleaners or work sites or even just asphalt can carry those things. Heavy metals, and of course, even things like animal waste. So you might not just come into physical contact with something unpleasant, but those things that I just mentioned could impact your air quality as well. So it's not just the ground, but the air that's impacted by wearing shoes in the house. People spend up to 90% of their time indoors, and according to a pair of environmental chemists, 30% of the matter that builds up in an indoor space is imported from the outside. Let's say you've got a hermetically sealed home. If you're going in and out of that house, especially with your shoes on, you're importing a lot of the air that builds up in that indoor space, and a lot of that can be coming from your shoes. Now, I did say at the start that it's not even close whether removing your shoes is more hygienic. It is more hygienic, that is true. But to be clear and to be fair, experts do point out that the amount of stuff that you track in on the bottom of your shoes is probably not enough to make a healthy adult sick. There are plenty of other sources of germs both in and outside your home that you come in contact with. Your kitchen sponge, for example, your smartphone, your pets, things like that. But if you have young children and they're still crawling around, if you have someone in your household who's immune compromised or you're immune compromised, if you are a guest at a no shoes home or you simply want less debris in your own space, whatever it might be, it's probably worth just kicking off your shoes before entering the home. We do that in our household. It is pretty natural. When people come over to our house, they pretty much take off their shoes. We don't always require it like we did when the kids were very young, but it is sort of customary in our house to do so. So it might be worth kicking off your shoes before entering your home or the home of someone else. All right, now, when we come back, we're going to talk about navigating a tricky balance, how to stay informed with all that is happening in the world today.
