All right, let's begin our walk around the body. We're going to start with heart health. So a study was just published in the journal Circulation, and this study looked at over 1 million cases of people who had acute coronary syndrome aces. And this is what you need to know. Exposure to air pollution can weaken your cardiovascular system and even trigger heart attacks. 00;00;21;06 - 00;00;43;00Speaker 1So that's what the study found, that pollutants in the air can actually trigger heart attacks in you. The study found that air pollutants like carbon monoxide, and nitrogen dioxide. And by the way, this is stuff that's very common cigarettes. This stuff can lead to an immediate worsening of your heart's health. I spoke to Dr. Puja publisher of the newsletter Health Stuff to Know, and this is what she had to say. 00;00;43;11 - 00;00;55;02Speaker 2Hey, everybody, look, the bottom line here is that we need to start understanding that pollution is having a direct impact on our bodies. This is no longer just a theoretical discussion, you guys. We have the proof. 00;00;56;03 - 00;01;11;20Speaker 1And finally, guys, for some of you, you may actually have a bad heart or bad lung help. And there's nothing wrong with this. So our doctors recommend that you consider wearing masks on days where you have heavy pollution in the atmosphere. This is going to help reduce the harm to your lungs. All right. This is a fun one. This falls under mental health and this is what you need to know. Research is showing that we're spending a lot of time on our screens. I think we all know this, but new data is now showing that it's not about the time we spend online. It's actually about the time where we spend online. 00;01;35;17 - 00;01;57;02Speaker 1So they're hinting social media is bad for you. Time magazine said it best. And here's the quote. Experts can't agree on how much screen time is too much for adults. And the content you're consuming actually matters more than the overall time you spend on your phone. So this is basically the conversation about are we spending too much online? 00;01;57;02 - 00;02;24;25Speaker 1And the new study now seems to be indicating it's not about the time we're spending online, it's how we're spending that time. Many people are surprised to learn that spending too much time on social media can lead to depression, anxiety and even obesity. Yeah, because you're not getting enough sleep, you're overeating. And this, of course, leads to weight gain So I reached out to Dr. Puja and I said, "Listen, Dr. Puja, I'm spending too much time and punishing my eyes and my mind." 00;02;25;02 - 00;02;25;29Speaker 1"What should I be doing?" 00;02;26;03 - 00;02;42;03Speaker 2Yeah, if you struggle with anxiety, or depression, start tracking the amount of time you're spending on social media. And if it's too much, please reduce it. Limit your time in social media to about 60 minutes a day. And if you're spending more time, don't be shy. Just tell me about it. OK, moving from mental health. Let's move on to GI Health. Here's what you need to know. There's a lot of research that's now started to show that fecal transplants may actually reduce the effects of aging and improve overall brain health. So, yeah, look, scientists are learning and they're learning very quickly that a healthy gut helps with the body's immune function and helps with a healthy metabolism. 00;03;11;28 - 00;03;38;07Speaker 1So the idea here is that by getting fresh fecal transplants from young, healthy people, we may be able to replenish our damaged gut. And this will help us as we get older So we spoke to a doctor and as a f.y.i. This is what they had to say. We're not quite at the level where people can go and get cosmetic fecal transplants before this starts happening and before this b...
