the most bitter days of

winter are still ahead. do you really know the tricks to staying well in the cold? in news4 your health debunking three cold weather myths. a family allergyist is here with the facts about staying well in winter. dr. jackie my mother when i was little would hit the roof when i left with my head uncovered. she said you have to wear a hat. many people believe a warm head is the most essential cold weather accessory because it keeps your body warm. that's myth number one. >> it is. and the mass just doesn't add up. it's just 10% of your area it's70% of your heat. keep your core warm. keep yourself clothed. the fabric you use should not be a sweaty fabric. and please be careful of your ears. if you don't want to wear a hat, wear an ear band especially if you put in the earbuds to listen to music. cold hard pieces of metal in your ear will cause pain. hat is not as important as socks?

>> socks. this was actually sort of an ice challenge test that was done ten years ago and made your mother correct. if you are are cold then you have a greater chance of getting a cold. what they did is put people's feet in iceor. then a couple of days later theyho did that to had more chances of getting a cold. so keep your feet warm and keep your body warm in generally, and you won't get a cold as easily. >> myth number two, a nice warm scarf wrapped fashionably around your neck will help keep you well. u pull it up over your face. what you want to do with the scarf is keep the air warm. you're breathing especially today, it's cold and dry. you need to make it humidified. runners are at a particular risk for this and they should wear maybe those neoprene scarves to keep things well hydrated in terms of their air and their breath. don't forget to hydrate themselves. >> and if you have asthma, the cold weather is even more dangerous. >> that's a trigger. we sometimes use it in a laboratory. we blow cold air at people to prove they have asthma.

it will give them bronco spasms. >> myth number three, at the first sign of cold ar flu start guzzling the orange juice and popping the vitamin c tablets. >> no, it doesn't make any difference. you can't just start taking all the grapefruit in the world when you get the cold. what matters is you've done it ahead of time that your immune system is overall supported from a healthy diet. the only medication that will make a difference if you actually get the flu is something like tamiflu. let me make sure everybody is aware you have to see the doctor as soon as you get the fever or at least within 48 hours. otherwise, we can't get you tamiflu again, the thing that matters most in really helping the flu is get the flu shot. i know it's not a perfect match, but some match is better than no match at all. >> spring is 65 days away. >> and don't -- we're waiting for it. the case against him has gone viral and a podcast called serial. we're getting a better idea of

whether he could soon be a free man. plus an officer's life saved. an unlikely person who came to the rescue just in time. a radio host tell us his terrifying story about what he experienced on metro the day of that deadly smoke. right

listeners are among those concerned. they want changes. >> absolutely. they're concerned because they rely on metro to get around town. they of course have to get to work back and forth, and metro is something we all rely on very quite honestly. but they're concerned about these emergencies they're seeing in the system, and they say there is a real problem with communication when s s on these trains. there will be cases where there are emergencies, but they say the information is not being relaid to passengers effectively, and they say s especially in d.c. if there's a push to us relying more on public transportation people telling us authorities telling us to park the car and take the train. what kind of a trade-off, people are asking are we getting if we're going to rely on this particular train system? >> you know the pictures that came in, a lot of people instead of waiting for emergency crews decided to self-evacuate. aloft your listeners say they would do the same thing, even though the experts say it's dangerous. >> right, it is. but when you see a train car

being filled with smoke, people are telling me that they were concerned. what would i do in that situation? is it fight or flight? what can you do? especially if you're talking about a mechanical failure and a time of danger. a lot of people saying they feel like they'd rather take their chances instead of being locked in a train car that is immobilized. >> who can blame them when they hear there's more smoke outside than inside the cars and they know it's only going to get worse. >> but again, as you mention, it's a very dangerous situation to be walking in the subway tunnels. >> sure. one of your on-air colleagues we hear actually saw what happened. tell us about that. >> our whor afternoon personality frank ski was on a train in a dangerous situation. here's what he witnessed. >> right before we hit la faunt

plaza, the conductor said, there's a stalled train in front of us. before the conductor came back on the whole train filled up with smoke. people were coughing, trying to get off the train. then the train just pulled off and kept going. i could tell people were like tripping like what is going on? in this time of terrorism, you never know what is going on. it was interesting that a lot of people were very upset that they weren't allowed off of the train at la font plaza and didn't know how they were going to get to where they were going. >> frank is echoing what i heard a lot from listeners. they want some accountability on this situation when it all weighs out. >> troy johnson, appreciate it. president obama wants to bring you faster and cheaper internet service. his announcement came from cedar falls, iowa, today. the small city has internet speeds that double those here in washington and in other major cities. the president wants to bring that to all cities and towns. he unveiled his plan to create

the irs commissioner put out a letter to its employees about how the budget cuts would be affecting everyone. the $600 million cut means the irs is forced to reduce taxpayer services like when you call the irs, you probably have a 50/50 of shot of actually speaking with someone and could find yourself on hold. that's because of reduced overtime in staffing. tax policy expert bill gale says it's a particularly bad time to cut resources. >> i think the implementation of the health care reform rules and its interaction with the tax system is going to cause considerable complications in large part because it's the first time we've been through this. >> tomorrow as part of our fresh start for your finances series, we're going to givu a heads-up on the four thing uz need to know before you tax return. and then tonight at 5:00 we are focusing on your credit score
