Hey, it's Marielle. A lot of us treat our bodies like they're our employees. You know, they work for us. And when they don't work for us, we get mad. We say mean things about them. We're frustrated. We're disappointed. The way I see it though, our bodies don't work for us. They work with us. And if we want to give them the best chance at doing that, we have to take care of them to give them regular attention so they can support us. Now I need to do a quick plug here for going to the doctor. Make sure you're getting your annual physicals and checking in with your healthcare providers as needed. Cause as we know, a podcast is not the same as professional medical advice. But beyond that, we wanna help you take care of your bodies. So on this episode, Life Kit reporter Andy Taegle has put together some of our favorite health tips from head to toe. We've got advice from an audiologist, an ophthalmologist, a dermatologist and more. That's after the break.

Andy Taegle
All right, first up, on our tour through the Body Magic School Bus style, shout out to all my fellow millennials who will forever adore Ms. Frizzle. Our ears feels appropriate since you're listening to a podcast right now. How's the volume on this episode? By the way? Is my voice coming through loud and clear? Good, so you can listen closely to our first reminder for hearing health. Learn the signs of noise induced hearing loss and don't forget to protect your ears, especially when you know you'll be around loud noises for a long time. Now, when you think about hearing loss, you might assume it's an older person's problem. But with the advent of personal audio devices, perhaps like the one you're listening to Right now, over 1 billion young people aged 12 to 35 are at risk of hearing loss due to prolonged and excessive exposure to loud sounds at dangerous levels. This is According to a 2019 report from the World Health Organization and the WHO projects nearly 2.5 billion people will have at least some degree of hearing loss by the year 2050. So how do you know if you're at risk for noise induced hearing loss and what can you do about it? Well, it sounds different for everyone, but it often happens gradually and there are a few common symptoms to be on.
- [04:06]
Ariella Naim
The lookout for when we have hearing loss that becomes harder to filter out the speech from the noise, or I should put it as the sound source that we want to hear versus the sounds that we don't want to hear.
- [04:17]
Andy Taegle
This is Ariella Naim, senior audiologist at Audio Help Hearing center in New York City, talking here in her office to Life KIT producer Margaret Serino, who originally reported on this topic. She says hearing loss is a result of damage either over time or from one big sudden noise to these teeny tiny hair cells in our ears that help convert sound frequencies into electrical signals.
- [04:41]
Ariella Naim
They won't transmit that sound as well to the brain because at the end of the day, and it's all about our brain hearing and our brain processing what's going on.
- [04:50]
Andy Taegle
So noise induced hearing loss isn't just about your ability to hear external sounds, it's also about your brain's ability to interpret them. For example, have you ever walked out of a concert and turned to talk to a friend, but you can't quite understand what they're saying? That muffled feeling is one sign to watch out for other signs if you have trouble following a conversation in noisy places, or if you struggle with or have hypersensitivity to particular sounds or tones of voice. But one of the most common symptoms to pay attention to is tinnitus. And yes, that is the correct pronunciation. It's usually defined by a ringing or buzzing in the ears or like the static on the TV or radio turned all the way up.
- [05:37]
Ariella Naim
And the number one cause of tinnitus is hearing loss.
- [05:41]
Andy Taegle
If any of this feels familiar, it's a good idea to get your hearing tested and establish what your baseline level of hearing is. You can talk to your primary care doctor about a referral for a full audiological exam or try a free test online. Hearingnumber.org or hearing.org are two good places to start. Now, the best way to prevent noise induced hearing loss, no big shocker here, is to protect your ears. But what might surprise you is how often they need protecting.
- [06:08]
Ariella Naim
The rule of thumb is that when you're listening to a sound at what's considered 85 decibels, you are safe.
- [06:16]
Andy Taegle
Some examples of 85 decibels of city traffic, a vacuum cleaner, a garbage disposal. So a fair amount of noise, but eight hours of exposure at 85 decibels can lead to hearing loss.
- [06:28]
Ariella Naim
And then when you increase that sound by 5 decibels, you have to cut the time in half.
- [06:35]
Andy Taegle
And let's note, recommendations vary here. Like the CDC's number is 3db, not 5, and our everyday world is loud. An approaching subway train, roughly 100 decibels. The music and sounds of a nightclub or bar, around 110 decibels. That level can actually damage your hearing in less than five minutes. Basically, it's like one big exponential curve where the louder the noise, the less time you can listen to it. Unprotected earplugs can help minimize that risk, although depending on the type, they likely won't block out everything you hear. They're usually just a good tool to take everything down a notch. In fact, if you love music and you want to preserve how it sounds, you can even get filtered plugs that can maintain that natural resonance of sound in music. And while over the ear muffs are better, those foam earplugs are still much better than nothing. You know the kind that they give out on airplanes? Just make sure you put them in properly.
- [07:30]
Ariella Naim
You roll them really thin into a small, small cylinder, pull your ear back and up, and then push them in nice and deep and let them expand.
- [07:38]
Andy Taegle
Besides earplugs, the other thing to watch is your phone volume. There's actually no official guidance on how loud is too loud. But here's Ariella's rule.
- [07:47]
Ariella Naim
As long as you play your music or podcast audiobook, anything like that, at 60% of the volume bar or less, you would be safe, which would still.
- [07:56]
Andy Taegle
Be plenty loud enough to enjoy this sweet outro music as we move into our next section. The Eyes to start if you're over 18, a comprehensive eye exam is recommended every two years. If you're in between visits and find your peepers give you trouble from time to time in our screen laden land. Our top tip for eye health when dealing with digital eye strain Aim for less screens, more sky, and don't forget to blink. There are a lot of myths and misconceptions out there about what affects the quality of your vision. One big example, blue light. This is a super hot topic in the eye world. Like maybe you're one of the many, many people who went out and got a pair of blue light glasses to protect your eyes in the beginning of the pandemic. Here's the thing.
- [08:42]
Dr. Rupa Wong
There have been absolutely no studies that have demonstrated any kind of negative effect of blue light on your retina, on your cataracts, on your macula. I think people get a little confused with ultraviolet light and blue lights from that perspective. But what blue light does is it affects your melatonin, it affects your circadian rhythms.
- [09:01]
Andy Taegle
This is Dr. Rupa Wong. She's an ophthalmologist and assistant clinical professor at the University of Hawaii John Byrne School of Medicine. And it's true, while research is still ongoing about the potential long term negative effects of blue light, Rupa and the American Academy of Ophthalmology say as things stand, blue light isn't really the bad guy. People often make it out to be sure, if you have a computer screen right next to your bed, it might mess with your sleep in the same way any other bright light would. But the real reason for your screen induced eye fatigue is likely much simpler.
- [09:34]
Dr. Rupa Wong
So digital eye strain, really. It comes down to the fact that when we are on devices, whether it be a computer or a phone or a tablet, we tend not to blink as much and we are focusing up close for many hours at a time.
- [09:48]
Andy Taegle
Yep, blinking. See, when you don't blink, your eyes get drier. Might not sound like a big deal.
- [09:54]
Dr. Rupa Wong
But the amazing thing is that your tear film is responsible for a good part of the clarity of your vision. When you have dry eyes, the vision becomes blurry. People don't come in saying I have dry eyes. They come in oftentimes saying my eyes hurt or my vision is blurred. There are a lot of different medical problems that can be associated with severe dry eye syndrome.
- [10:18]
Andy Taegle
Some quick fixes. You could keep artificial tears handy, not eye drops. There is a difference. You could start or end the day with a few minutes of warm compresses over your eyes to moisturize the oil glands on your eyelids. But if nothing else, try to regularly practice the 202020 rule. That is for every 20 minutes of screen time, take a 20 second break and look 20ft away. And that doesn't have to be 20ft exactly. Mind you, it just means look at something off in the distance because when your eyes are looking farther away, they're more relaxed. And that's important because some of the things that can actually affect your prescription aren't always in our control. Some conditions, like cataracts, are age related. Others can be related to diabetes or high blood pressure. But there is one factor we do have some power over.
- [11:08]
Dr. Rupa Wong
Near work is associated with becoming nearsighted.
- [11:11]
Andy Taegle
Near work is what it sounds like any work that you focus on up close, like within arm's reach. So almost all screen time would apply, but also reading, drawing, sewing and studies have shown that increased and continuous time spent on near work is linked to increased risk of nearsightedness. Luckily, the fix is as simple as you think it might be.
- [11:33]
Dr. Rupa Wong
Being outside is so crucial, especially in my younger patient population.
- [11:38]
Andy Taegle
Recent research suggests regular outside time for kids, like up to two hours a day, may help slow or even prevent nearsightedness. That might be because when you're outside looking at nature, you're spending less time looking at things so close up and thus letting your eyes rest. Or maybe because sunlight slows eye growth, that could help eyes from unnaturally elongating, which is a cause of nearsightedness. So get out in the sunshine and go look at some trees, will ya. Ophthalmologist's orders. Up next, a quick break, then back to checking in with our bodies.

A big dose of sunshine, let's quickly check in on that Great big nature induced smile on your face. Before we move into our next section, here are a few quick dental health reminders to chew on. Inspired by our teeth episode, the American Dental association recommends seeing your dentist regularly for prevention and treatment of oral disease. So if you can't remember the last time you went, it's probably been too long and it's important to keep those appointments. Oral health is a window to the overall health of your body as the entry point for your digestive and respiratory tracts. So having poor oral health, like gum disease, can play a part in other conditions like cardiovascular disease, pneumonia, even pregnancy or birth complications. Finally, for clean teeth, focus on technique, not just tools. You should replace your toothbrush every three to four months. And yes, a good toothpaste will make your mouth feel clean, but as long as you're doing it right, brushing with just water can be enough. So you want to brush each tooth slightly, sweeping the gum line with your brush at a 45 degree angle for two minutes, making sure to hit each quadrant of your teeth twice a day. And floss once a day to keep those pearly whites strong. Okay, now, how does that song go? Head, shoulders, knees and toes. Let's get you walking into this next season feeling fresh and fancy footed. Our next tip, good footwear is good foot care, and so is going to the foot gym. Okay, now I know a lot of people don't like to look at, talk about, or even think about their feet, toes and toenails. Heel skin evoke a general sense of ick, perhaps. But let's all take a step back from the aesthetics of feet and just think about their utility.
- [14:46]
Irene Davis
They're a base of support. They can become a spring. They become mobile adapters to uneven terrain and, and yet sometimes they have to be rigid for push off. So yes, they're really critical structures, and I think they're very highly underappreciated.
- [15:02]
Andy Taegle
Irene Davis is a professor of physical therapy and rehab sciences at the University of South Florida. She has spent decades researching the biomechanics of feet and the lower extremities. And she says, our feet do so much for us. For starters, they take 5,000 steps a day on average. So why wouldn't you do everything you can to take care of them? Like when it comes to footwear, for example? Irene says it's pretty simple. It shouldn't feel better to take your shoes off.
- [15:31]
Irene Davis
I guess it'll always feel a little bit better.
- [15:32]
Andy Taegle
It's.
- [15:33]
Irene Davis
Maybe that's extreme, but you know how people like, I just can't wait to take my shoes off. That shoe's not a good shoe for you.
- [15:38]
Andy Taegle
There are a lot of little assumptions we make about our footwear. For example, when was the last time you got your shoe size checked? Even though generally the bones of your feet stop growing longer when you stop growing in height, your shoe size can still change, famously from pregnancy, but also weight fluctuations, aging, or just general wear and tear. And when it comes to walking or running shoes specifically, it's a good idea to wear a half or even a full size up because your feet often swell when you walk or run for long periods of time. General guidance says you want to replace these kinds of shoes every six to.
- [16:12]
Dr. Adam 1040
12 months, or we typically will say 350 to 500 miles. And common errors, of course, are that maybe you both run and walk around in the same pair of shoes. Well, all those miles count.
- [16:26]
Andy Taegle
That's Dr. Adam 1040, a professor in physical medicine and rehabilitation at Harvard Medical School. He says it's important to regularly replace your shoes because any padding will slowly wear away from use friction with the ground weather, and that shoe will start to put more and more demand on your foot and ankle, which can make you more prone to injury.
- [16:47]
Dr. Adam 1040
Another piece is that we're asking our foot to be supported by this footwear. And so if other aspects of the footwear are wearing out, it affects our biomechanics with walking and with other daily function.
- [16:59]
Andy Taegle
For the front of your shoe or your toe box, you need the rule of thumb. As in, you want about a half a thumb to a thumb's width between the end of your longest toe and the top of your shoe.
- [17:09]
Dr. Adam 1040
The third part is really the width of the shoe. We don't want to crowd our toes.
- [17:15]
Andy Taegle
In fact, you want wiggle room in all directions for all types of shoes, including those super cute but highly impractical 6 inch heels. Yes, you can still wear them and have healthy feet as long as you're.
- [17:28]
Irene Davis
Not wearing them all day long. Because there's been a lot of studies have shown that, you know, wearing them all day long ends up causing problems with the Achilles and you get problems with the forefoot.
- [17:38]
Andy Taegle
So just be smart, take breaks, bring backups and make those show stopping but toe numbing after 10 minutes type of shoes. The exception, not the rule. Now, arguably even more important than what you put on your feet is how you train them, especially if you're prone to aches and pains. Your feet have lots of muscles, and just like any other part of the body, the stronger they are, the better protected you'll be against future injury. But for now we're just dipping our toes in the water of that foot health pool. We've got a whole episode on this topic, plus an article complete with gifs of foot strengthening exercises to help get you moving. So don't walk. Run on over to npr.org lifekit after.
- [18:20]
Irene Davis
This because we have to show our feet love because they gotta last us a lifetime.
- [18:30]
Andy Taegle
Now before I let you go, an episode on head to toe health just would not feel complete without one last incredibly apropos tip from dermatologist Sonia Vetra. She's here to lead us through our last section, Best Practices for Bathing and Skincare.
- [18:44]
Sonia Vetra
Head to toe is the way to go because surprisingly there there are a lot of questions about this. Like something we all do every day.
- [18:50]
Andy Taegle
That is when it's time to hop in the bath or shower. After a productive day of health maintenance and such, you want to work from top to bottom, front to back. You know, shampoo, conditioner, face wash, then soaping and scrubbing all your bits or at least your most sweat, odor and bacteria prone places, working down to your feet. That way you're not bringing any dirt or debris back up your body, especially.
- [19:16]
Sonia Vetra
If you're acne prone or breakout prone. I always recommend that you do your shampoo and your conditioner first because any residue from those products you're going to want to make sure isn't left on your back which can break you out and cause back knee.
- [19:28]
Andy Taegle
It might sound super simple, but you want to be brilliant in the basics as they say. That's why our final bit of advice for a healthy body this fall is bathe better. Be it bath or shower, keep them not too hot, not too long, and don't forget to clean your cleaning products. It might surprise you to know the subject of bathing can get a bit controversial. For example, if you love a long, luxurious soak in the tub, you're probably not going to like what Sonia has to say next.
- [19:59]
Sonia Vetra
I would say, you know, less than five minutes if you can, maximum 10 on a really long shower day. It's also, you know, obviously not wasting water that way too, because let's face it, we can all get clean in a pretty efficient window of time.
- [20:11]
Andy Taegle
Sonia sympathizes with anyone out there like me who loves collecting shower thoughts and slowly turning into a raisin at the end of a hard day. But she says long, hot, steamy showers are really not a good idea, especially as the weather starts to turn.
- [20:26]
Sonia Vetra
Every organ in your body has a function, right? Like your heart is designed to pump, your lungs are designed to breathe, and your skin's function as an organ is to be a barrier that keeps the outside world out. And so one of the really critical components of that barrier is the fats in your skin. Immersion and long, extended exposures to hot water really dehydrate your skin and break down the barrier.
- [20:50]
Andy Taegle
So if you're used to your bath water steaming and sizzling, turning your skin itchy, splotchy red, it's time to turn the temperature down. You could go for cold water instead. Cold plunges won't dry you out and are awful popular these days for benefits like increasing circulation and reducing inflammation. But in Sony's opinion, lukewarm water, like somewhere around the range of body temperature, is the best way to take care of your skin so that your skin in turn can take care of you. Next up, bath or shower, washcloth or loofah. There's no scientific hardline on either of these, although from an eco friendly standpoint, the EPA says showers generally save more water, so that's something to consider. When it comes to cleaning tools, Sonia prefers options that will be gentler on your skin, but she says whatever you use, just clean them daily.
- [21:40]
Sonia Vetra
Remember yeast bacteria? They love a really warm, moist environment, which is of course your shower.
- [21:47]
Andy Taegle
So if you use a loofah washcloth or similar, be sure to thoroughly wash and rinse it after every use. Then wring out your tool and leave it somewhere it can dry all the way. That means not just hanging it on the wall of the shower or the head of the bath faucet, where it's likely to get wet again when your partner takes a dip in half an hour. If you're team washcloth, change them out regularly. Sonia throws hers in the wash at least once a week with the rest of her towels. For loofah users, a weekly deep clean by submerging it in boiling water is a good idea to disinfect it and be on the lookout for any signs of mold with any type of tool. But for loofahs especially, and in general.
- [22:25]
Sonia Vetra
Even if it's not changing color and it's not smelly, I would say throw it out every two months.
- [22:29]
Andy Taegle
Regardless, guidance from the Cleveland Clinic suggests an even smaller window of time for safety. You want to discard natural made loofahs after one month, plastic loofahs after two, or right away if you notice any mold, discoloration or unsavory odor. Surprising, right? Was for me, and also potentially pretty wasteful. So maybe this is the moment for all of us on Team Loofah to consider switching sides. But no matter your preference, don't forget to enjoy a little care and keeping of you. Brief though these moments may be, here's to hoping we can all luxuriate in good health in the future.
- [23:05]
Sonia Vetra
So even if it's that two minutes, I'm sorry it's not 20. But even if it's that two minutes in the shower just to reconnect with yourself, I'm all in favor of it. And if you follow best practices, even better.
- [23:19]
Andy Taegle
Alright, let's review for your ears. Learn the signs of noise induced hearing loss. Protect your ears anytime your round sounds louder than a vacuum cleaner. And keep some earplugs close. You never know when you might need them for eye health. Remember 202020 for every 20 minutes of screen time, take a 20 second break and look 20ft or so away. The more you can get your eyes outside, the better. Quick reminder for oral health. It's a window to your health overall, so use the right technique twice daily. And don't forget, floss first. Also, good footwear is good foot care. Get resized every so often. Replace old walking and running shoes to avoid pain and injury and make sure the new ones give your tootsies enough room to breathe. We only get one pair of feet. Be good to them. Finally, to treat your whole body well, bathe better. Be it bath or shower, keep them not too hot, not too long, and don't forget to clean your cleaning products.
