joining us now, pulmonologist and msnbc medical contributor, doctor vin gupta. the first thing you're going to say to me, doctor, is put on my mask. >> that's right. >> but you bring up something really important that we need to talk about. >> people think in 95. >> respirator. >> katie, you and i have talked about that mask. >> how many years now? for various reasons. that does not do the trick when it comes to dealing with volatile organic gases that get emitted in the setting of wildfire smoke. >> so you nailed it. >> there's more than just the soot that you can breathe in, that you can see on your mask. >> and so if you're going to be out a gas mask, p100, especially for firefighters out there, are reporters really, really critical p100 gas mask. >> that's what blocks out those volatile organic compounds from from going into your lungs more broadly for everybody watching. and katie, this is really, really important. this can save lives. this is not going to be the last fire, sadly, that we face in southern california or across the country. less than 30% of h

vin gupta? in fact, it was, living his best life, practicing what he preaches.said, there are multiple factors at play, including whether or not you drink. >> holistic health, poured -- >> oh, my god, yes. >> this is either really light white wine or water. >> or tequila? >> so, this is it. here is the benefit to this is a properly poured want here is -- you're getting dual advice, medical and winetasting advice. you want the wine to come up of the wineglass, where it is widest. that is where you want the wine to hit you do not wanted to go after. the goals not to pour as much wine has fits in the wineglass. that is not a proper glass of wine. it is up to the widest point. here's the benefit from the winetasting perspective. it will create the most amount of surface area for oxidation, so it will be better tasting wine and better for your health and you will not risk over drinking and that is really the they have -- they are not safe in any amount. there is a carcinogen. they are a carcinogen that we have known. i'm glad this is out there. other potential heart

vin gupta. always great to have you. >>> there is much more news ahead. >> do not go anywhere. you are watching "nbc news you are watching "nbc news daily". when my doctor gave me breztri for my copd... i noticed things changed. breztri gave me better breathing starting within 5 minutes. it also reduced flare-ups. breztri won't replace a rescue inhaler... for sudden breathing problems. it is not for asthma. tell your doctor if you have a heart condition or high blood pressure before taking it. don't take breztri more than prescribed. breztri may increase your risk of thrush, pneumonia, and osteoporosis. call your doctor if worsened breathing, chest pain, mouth or tongue swelling ...problems urinating vision changes, or eye pain occur. ask your doctor about breztri. vision changes, or eye pain occur. new to the big city? yeah. -i'm mara. -hi. apparently progressive lets homeowners and renters bundle with their auto policy. 24/7 protection for all of my...things.

vin gupta. good to see you.ntial to be a game-changer for people suffering with pain. what is it, and what kind of pain are we talking about it might be able to treat? >> you know, kate, there has not been innovation in pain medication development for years. so this is actually targeting a different receptor in the body. very different from the opioid rcotics that work on receptors in our brain. this is great news for those with acute pain. to answer your second question, right after a procedure or they've just been discharged from the hospital, acute pain that is intense and severe. this is where it can help alleviate it. big, big news. we haven't had innovation in this space. >> for people with acute pain, sounds like more than what you'd take ibuprofen for, right? is it supposed to be an alternative to ibuprofen or more? >> what we know from the studies that they used to approve it is this is for acute pain. post surgical, hospital related pain. not necessarily chronic pain that you'd take an ibuprofen or tyl

vin gupta. so good to see you.n the norovirus, anecdotally seems like a lot of people are sick right now, and deeply unpleasant, why is it spiking and how can we mitigate it? >> it's the winter vomiting bug, so i know nobody wants to talk about that, but here we are. tends to spike between november and april. this year seems like an outlying year with more cases. we don't know why. we're all indoors, a lot of us traveling. maybe the spike is an anomaly but there's a reason we're seeing it right now. here's how to distinguish it. the question i get all the time is, how do you know it's norovirus versus, say, something else that might cause gi upset? it's about hallmark -- the rapidity of symptom onset, how quickly it happens after someone ate oysters, which has been implicated in norovirus outbreaks. it happens quickly, maybe in a matter of minutes, and that's something to keep in mind. that's you or a loved one you know, it should stay home and try to stay isolated from other people not handling food. the really cr

vin gupta. dr. gupta, jacob had his mask on. he took it off because the wind shifted. but i trust he's taking the advice of the experts on the ground. tell us what people in and around los angeles affected by the fires and near them need to know today. >> yeah, of course. very moving segment, just catching that with you and jacob. first of all, just thank you for sharing that and for letting jacob share how meaningful all of this is really to him from a personal standpoint. that affected me just listening to that. to the matter at hand, though, from a health standpoint, there's things that every one of your viewers, especially in the l.a. county area, but frankly, given the world we live in, nicolle, need to keep in mind, smoke is a reality for most of the country now, but especially now in southern california. so i want to divide it into a few things, but acutely, if you are facing flames as we speak in some form, if you're close to a fire, often what happens, and this gets underplayed, is that acute smoke exposure, nicolle, far away from flames, can be as dangerous,
