Listener Question 1: How Do I Avoid Pneumonia?

Caller: Mark from New York City
Timestamp: [00:20]

Overview of Pneumonia Risks

Dr. Gupta begins by emphasizing the severity of pneumonia, particularly among older adults. He states, “Nearly a million older adults are hospitalized with pneumonia every year, and over a third of them will die within a year” (00:33). While older adults are at higher risk, pneumonia can also pose serious threats to young children, immunocompromised individuals, and those with underlying health conditions.

Prevention Strategies

To mitigate the risk of pneumonia, Dr. Gupta outlines several preventive measures:

• Vaccinations:

  • Pneumonia Vaccines: Particularly recommended for children, with booster shots advised at age 50 and possibly at 65.
  • Flu Shots: Essential for preventing infections that can lead to pneumonia.
  • RSV Vaccine: Recommended for adults aged 75 and older, and for those aged 60 to 74 who are at higher risk (00:33).

• Understanding Respiratory Infections:
  Dr. Gupta differentiates between the upper and lower respiratory tracts, clarifying that pneumonia is an infection of the lower respiratory tract, typically caused by bacteria such as streptococcus (00:33).

Diagnosis and Treatment

Pneumonia is usually diagnosed through a physical exam and a chest X-ray. Dr. Gupta explains that while antibiotics are effective against bacterial pneumonia—which accounts for 60 to 70% of cases—viral pneumonias do not respond to antibiotics (00:33). He also discusses "walking pneumonia," a milder form that affects all lung lobes but often does not require antibiotics and can be managed with over-the-counter medications (00:33).

Lifestyle Factors to Lower Risk

Maintaining a strong immune system is crucial in preventing pneumonia. Dr. Gupta recommends:

• Healthy Diet: Consuming plenty of fruits, vegetables, and whole foods.
• Regular Exercise: Engaging in activities like brisk walking helps release pathogen-fighting components in the blood.
• Adequate Sleep: Ensuring quality sleep to provide the body with the energy needed to fight infections (00:33).

Transmission Prevention

Pneumonia spreads through respiratory droplets from coughing and sneezing. Dr. Gupta advises:

• Wearing High Filtration Masks: Especially around sick individuals.
• Maintaining Clean Surfaces and Hand Hygiene: To prevent indirect transmission.
• Avoiding High-Risk Settings: Reducing exposure to environments where viruses are prevalent (00:33).

Notable Quotes:

• “Pneumonia can start to be this trajectory towards a pretty serious illness.” – Dr. Sanjay Gupta (00:33)
• “Your immune system is constantly fighting off pathogens.” – Dr. Sanjay Gupta (00:33)

Listener Question 2: Are Night Owls Lazy?

Caller: Casey from San Diego, California
Timestamp: [06:37]

Introduction to Chronotypes

Casey inquires about the perception of night owls being labeled as lazy and seeks to understand the neurological differences associated with this sleep pattern. Dr. Gupta clarifies that being a night owl is not a matter of laziness but is influenced by biological factors known as sleep chronotypes (06:44).

Biological Basis of Sleep Patterns

Dr. Gupta explains that an individual's circadian rhythm—the internal clock regulating sleep, digestion, body temperature, and mood—largely determines whether they are a morning person or a night owl (06:44). For night owls, the production of melatonin, the hormone responsible for sleep, begins later in the evening, making them naturally more alert at night and inclined to wake later in the morning (06:44).

Research Findings

Referencing a study from Imperial College, Dr. Gupta shares that night owls scored higher on cognitive tests compared to early risers. The study involved over 26,000 participants and categorized them based on their chronotypes (06:44). This finding challenges the stereotype that early risers are inherently more productive or successful.

Health Implications

While night owls may have cognitive advantages, Dr. Gupta addresses potential health risks associated with this chronotype, including higher chances of developing chronic diseases such as heart disease, diabetes, and depression (06:44). However, he notes that these risks are often linked to lifestyle choices common among night owls, such as irregular sleep patterns, excessive screen time, and poor dietary habits.

Strategies for Night Owls

For those concerned about the drawbacks of being a night owl, Dr. Gupta offers several strategies to help adjust sleep patterns:

• Exposure to Natural Light:
  “As soon as your alarm goes off in the morning, turn on the light and try and get as much natural light as possible” (06:44).

• Dietary Adjustments:
  Stop eating at least three hours before bedtime to improve sleep quality (06:44).

• Exercise Timing:
  Engage in regular exercise earlier in the day to support the body's internal clock (06:44).

• Screen Time Management:
  Reduce screen exposure before bed to allow melatonin production, replacing it with relaxing activities like reading or meditation (06:44).

• Relaxation Techniques:
  Practices such as yoga Nidra can help wind down and prepare the body for sleep (06:44).

Dr. Gupta emphasizes that being a night owl does not equate to laziness and advises focusing on quality sleep and establishing a consistent routine that aligns with one's natural chronotype (06:44).

Notable Quotes:

• “Being a night owl isn't simply a matter of preference or being lazy. In many ways, it is biological.” – Dr. Sanjay Gupta (06:44)
• “Night owls actually scored on average, higher on cognitive tests than early risers.” – Dr. Sanjay Gupta (06:44)
• “You are not lazy. Neither is Abby. Philip, your body just works differently.” – Dr. Sanjay Gupta (07:17)

Conclusion

In this episode, Dr. Sanjay Gupta provides comprehensive insights into pneumonia prevention, highlighting the importance of vaccinations, lifestyle choices, and hygiene practices in reducing risk. Additionally, he addresses misconceptions about night owls, explaining the biological underpinnings of sleep patterns and offering practical strategies for those looking to adjust their chronotypes.

Transcript

[Sanjay Gupta]

Welcome to Paging Dr. Gupta. This is the podcast where I get to answer your health questions, which I love doing. You've been sending in some really great questions, so there's a lot to get to today. And Kira, who you're getting to know, one of our producers. She's back with me. Kira, what do we have first?

[Kira Dehring]

Hey, Sanjay, Glad to be back. So, our first question today is coming from Mark in New York City. He's in his 50s and wants to know, how do I avoid pneumonia?

[Sanjay Gupta]

All right, Mark, great question. Pneumonia has been in the news quite a bit lately and it can be a serious threat, especially as we get older. In fact, nearly a million older adults are hospitalized with pneumonia every year, and over a third of them will die within a year. So pneumonia can start to be this trajectory towards a pretty serious illness. While older adults are the ones that we typically think about facing the highest risk, it can also be severe for young children, for immunocompromised individuals and those with serious health conditions. Now, there's good news here in that there's a lot you can do to lower your risk. There are vaccines for pneumonia, specifically, typically for children. And then at age 50, with a possible booster at age 65, getting the flu shot. That can help prevent infections that can lead to pneumonia. And if you're eligible, there's also the RSV vaccine. This can offer some extra protection. The CDC recommends it for adults 75 and older and those who are 60 to 74 who are considered higher risk. So pneumonia, just keep in mind it's an infection of the lungs. There's the upper respiratory tract, there's the lower respiratory tract. Upper respiratory tract is going to be more in your throat, in your nose. Lower respiratory tract is pneumonia. Now, people can have bronchitis. That's typically an inflammation of the airways inside your lungs. But pneumonia is an actual infection. Typically, it's a bacterial infection actually caused by something known as streptococcus. Now, you can take antibiotics for that. You take antibiotics for bacterial infections, but there can also be viral pneumonias which would not respond to antibiotics. But about 60 to 70% of pneumonias are actually caused by bacteria. So the vast majority are going to be caused by bacteria. They can be diagnosed with a physical exam and a chest X ray. You may have also heard, Mark, I'll mention walking pneumonia. Walking pneumonia is kind of what it sounds like. It's a pneumonia where you can still be up walking around, so it's less severe. And oftentimes it is also diagnosed by physical exam and a Chest X ray. Interestingly, with a standard pneumonia, it typically affects one area of the lung, so one of the lobes of the lung. With the walking pneumonia, even though it is less severe in terms of symptoms, it does tend to affect all of the lungs. All the lobes of the lungs. But with walking pneumonia, you typically don't need to take antibiotics. You can typically treat that with over the counter medications. There are things that increase your risk and you should cut back on those things. Smoking is an obvious one. Heavy drinking that can weaken your immune system, make you more vulnerable. And as I'll talk about on this podcast all the time, supporting your immune system. Your immune system is constantly fighting off pathogens. It's doing it right now, probably. As you're listening to this podcast, you want to make sure your immune system is as strong as possible. Lots of fruits and veggies and whole foods. Regular exercise that helps release a lot of those pathogen fighting components in your blood. Even just brisk walking can go a long way. Prioritize good sleep. Your body needs that energy to be able to fight off infections. And you know, when you think about pneumonia, you think about respiratory infections. The way that they spread is by coughing and sneezing and putting those respiratory droplets into the air. Someone else can breathe those in. So you may want to protect yourself, especially if you're around sick people, by wearing a high filtration mask. Those droplets can also get on surfaces and people may touch those surfaces and then touch their eyes, their nose or their mouth. So make sure surfaces are clean. Make sure your hands are clean. Avoid people who are obviously sick. Be mindful of spending time in high risk settings where you think a lot of viruses are going to go around. So Mark, that's basically it. You can do a lot of things to try and prevent or at least reduce your risk of getting pneumonia. And you're already on the right track just for asking. Okay, we got time for one more question right after the break.

[Sanjay Gupta]

All right, Kira, sounds like it's time to answer another page.

[Kira Dehring]

Yes, it is. We have Casey here who called in for her question from San Diego, California. Take a listen.

[Casey]

Hi Sanjay, it's Casey. And I was going to suggest some future topics that are of interest to me, mostly for selfish reasons, I'm not going to lie. But one was about people who are night owls. That's me. And how their brains are different. I was listening to Abby Phillips and she was talking about being a night owl and, you know, having to deal with being perceived as being lazy by everybody. So I just thought that was interesting because I suffer that same characterization by people. So thank you for your time.

[Sanjay Gupta]

Bye. Okay, really interesting, Casey, thanks for calling in. First of all, I just want to say that I know Abby, Philip. I know her well. She's a colleague. She's a friend. She is not lazy. She works really hard. You have no idea how hard it is to anchor some of these shows and the amount of work you got to do to make them as good as she does on a regular basis. Let me start off by saying this. Being a night owl isn't simply a matter of preference or being lazy. In many ways, it is biological. I mean, nothing is entirely biological. There's always a nature and nurture component to just about everything. But there is a big sort of biological component to what is known as your sleep chronotype. Whether you naturally wake up early or whether you stay up late is largely driven by your own circadian rhythm. Your circadian rhythm. Think of that as your Internal clock that regulates all sorts of functions. Sleep, yes, but also digestion and your body temperature and your mood. There are reasons people like to eat at certain times. There are reasons they may feel cold or colder at certain times of the day and why they may feel a little bit more anxious or energetic at certain times of the day. And obviously, again, sleep when you may feel tired or more awake at certain times of the day. All of that has to do with your circadian rhythms. If you want to describe it even further. For night owls, melatonin, which is the hormone of darkness, the hormone of sleep, melatonin, something that people will take to help fall asleep, you naturally produce this, but for night owls, that production starts later, and that makes it natural to be more alert at night and to sleep in later in the morning. Now, I'm the opposite. I'm an early bird. I've always been an early bird. I think it's one of those things that probably helped me get through a pretty brutal seven years of neurosurgical residency. I was getting up at 5:00 in the morning to make rounds on time, but I was really good at that time of day. I spring out of bed first thing in the morning. My wife, incidentally, is a night owl. So that makes for an interesting marriage. I think it actually works, especially when our kids were young, because I'd get up early with them, she'd stay up late with them. It's a whole thing. Now, there is some research to prove for you, Casey, that night owls have some advantages. There was a study from Imperial College which found that night owls actually scored on average, higher on cognitive tests than early risers. I was surprised to read this study, you know, being a early morning person myself. But they actually studied over 26,000 people and they categorized them by this chronotype that I'm talking about, morning person, night owl, or somewhere in between. But the findings, I think they help challenge the stereotype that you're raising about early risers versus night owls being more productive or successful. Now, there are some downsides, as there are for most things in life. Other studies have shown that night owls are at higher risk for chronic diseases like heart disease, diabetes, even depression. But what they find when they dig into that a little bit more deeply is that that is often tied to lifestyle choices that go along with being a night owl. What are you doing when you're staying up late, Doom scrolling on your phone, probably skipping breakfast the next day, and you might have more irregular sleep, and that just throws off your internal clock. But if being a night owl worries you, there are some things you can do to help flip your body's switch from night to day at least a little bit. Again, there's a nature nurture component to everything. First of all, as soon as your alarm goes off in the morning, turn on the light and try and get as much natural light as possible. I always say open your shades before you look at your phone. Just get that natural light into your eyes. That kind of helps reset your internal clock. Makes waking up earlier easier. Next, stop eating at least three hours before bed. And if you regularly exercise, which you should try and do it earlier in the day. Also, those screens, I mean, those screens have really changed how we sleep overall as a world, not just a country. Turn off the screen earlier. This allows your body to start producing melatonin, the hormone of darkness that helps you wind down. If you are still awake, try replacing the screen time with reading or even meditation. I've started doing yoga, Nidra. If you don't know what that is, look it up. It can be very, very relaxing. Whatever helps you relax, do something like that. Bottom line, Casey, you are not lazy. Neither is Abby. Philip, your body just works differently. Focus on getting enough quality sleep and finding a routine that works for you. I think that's all we have for today's episode, but if you have other health questions that are keeping you up at night, literally or figuratively, I want to know. I love these questions.
