00:01 Welcome back.
00:03 We've been talking with Dr. Neil Nedley. 00:04 We've been talking about how to avoid 00:06 making big mistakes concerning your health. 00:08 Dr. Neil, I just want to clarify something. 00:10 You know, we were talking about 00:11 sexually transmitted diseases 00:13 and you've talked about, 00:14 you know, females that have had only one sexual partner, 00:19 had a 20 percent chance of having 00:21 a sexually transmitted disease. 00:23 But then you said something 00:24 about two or more partners and clarify for us. 00:28 Yeah, this was a study done 00:29 by the Center of Disease Control, Dr. Sara Forhan. 00:33 And it should among those girls 00:35 who had sexually transmitted disease 00:37 is 15 percent of them currently had 00:39 more than one sexually transmitted disease. 00:42 And among the girls aged 14 to 19, 00:45 who would ever have sex, 00:48 40 percent of them 00:50 had at least one sexually transmitted disease. Wow! 00:53 So that means it's, 00:54 you know, almost a one in two chance. 00:57 If you're going to choose to start having sex 00:59 between ages 14 and 19 01:01 then you're gonna end up 01:02 with a sexually transmitted disease fairly quickly. 01:04 Which could lead to infertility, 01:06 it could lead to your own personal discomfort, 01:08 or worse death. Exactly.! 01:10 Well, let's go to some good news. 01:13 You wanted to tell us about, 01:15 you know, how to avoid the double whammy 01:16 of frontal lobe hits with loud music and alcohol 01:19 and then losing all your money in casinos, 01:20 but what about some good news. 01:22 You have something to tell us about a natural high 01:24 that you can get, that's a positive study. 01:28 Yeah, we actually need to be choosing 01:30 natural methods of getting our highs. 01:33 You know, when we use a drug like a nicotine or cocaine, 01:36 there's a dopamine surge but then, 01:39 and of course that's why people do it. 01:40 It makes them feel great, 01:41 actually higher then they really should be feeling. 01:45 But then afterwards there is a depravation period. 01:48 And the more they do it, 01:49 the more that depravation occurs. 01:51 And this study that's being demonstrated on the screen 01:55 shows one of the ways of getting a Natural High 01:59 is when mothers see their own infant faces. 02:03 And what happen is key areas of the brain 02:05 associated with reward 02:07 actually lid up during the brain scans. 02:10 This is when they smile 02:11 or when they were changing their diaper? 02:12 Well this was particularly when the baby was smiling 02:15 or when the baby was neutral. 02:18 These areas stimulated by side of their own babies 02:20 were involved in thinking, 02:22 movement, behavior and emotion. 02:25 And these are the same areas 02:27 that are activated in other experiments 02:30 by utilizing drugs. 02:32 And so the studies investigator 02:34 Dr. Strathearn mentioned, 02:37 she is from the Human Neuroimaging Laboratory, 02:39 in Baylor College of Medicine at Houston. 02:42 She said maybe that seeing your own baby smiling face 02:47 is like a Natural High. 02:50 Well that sounds good news and of course you know, 02:53 my wife stays with the kids all day. 02:54 So she is able to get 02:57 a whole bunch of Natural Highs. 02:59 I certainly know when I come home 03:00 I look at the kids and I go, 03:02 nothing likes to feel better when your kids coming 03:04 over to give you a hug 03:05 and then spending time with them. 03:07 And now this, you know, 03:09 I think some moms sometimes think, 03:10 oh I'll be down and out, 03:11 but this is a great thing for the brain. 03:14 It's a great thing for the brain 03:15 and the nice thing about it is you don't get 03:17 the depravation period afterwards. 03:19 In other words the more your baby smiles 03:21 and the more you with your baby, 03:23 unlike using a drug where in between times 03:26 you get this big depravation periods 03:28 where there is no joy in life 03:30 even if you're looking at a smiling baby 03:32 or beautiful sunset, 03:34 because the neurochemistry has been altered adversely 03:37 from the use of these drugs, 03:39 this isn't the case with a smiling baby. 03:41 In other words, two years later 03:44 getting that Natural High from that smiling baby 03:46 will be just as high experience 03:49 as it was beforehand. 03:50 So what about watching DVDs of your kids, 03:52 Do you think that do the same thing, 03:54 watching them smiling? 03:55 Well actually the study took a look at pictures 03:58 and when the mother was separated from their baby, 04:02 and they saw a picture of their own baby smiling, 04:05 it still lid up in the brain. 04:07 And so there are advantages even at looking 04:10 at your babies pictures at certain times. 04:13 I can hear the photographers out there saying, 04:14 I got to use that study in my work. 04:18 More Time Outdoors! 04:20 By the way that study was published 04:21 in the journal Pediatrics in July of 2008. 04:25 July 2008! More Time Outdoors! 04:28 Yes, this is a very interesting study 04:30 showing that parents now have another reason 04:34 to shoo their kids outdoors to play, 04:36 along with making sure 04:37 they get enough fresh air and exercise. 04:40 This was a study done by Australian researchers. 04:43 And they found that children 04:44 who spend the most time outdoors 04:46 were the least likely to suffer from Myopia. 04:49 Nearsightedness! Which is...right, 04:51 nearsightedness or shortsightedness. 04:53 Our evidence suggests that the key factor 04:55 is being outdoors and does not matter 04:58 if that time is spent in having a picnic 05:00 or playing a sport 05:02 or whatever your child is doing outdoors. 05:04 It actually protects your eyes 05:06 from growing excessively, 05:08 which is the major cause of Myopia. 05:11 I want to know how that works. 05:12 Was that because you have to change your full vision? 05:14 You're looking the things three dimensional, 05:16 things far away, things near. 05:17 They're not sure how it works. 05:19 You know, there is some postulation about it 05:21 and that postulation is that, 05:24 you know, your pupils constrict more 05:27 when it's outdoor light 05:29 and so there isn't the need maybe felt for the eye 05:34 to grow excessively. 05:36 But we do know that nearsightedness 05:39 is a major problem in our society 05:41 and it didn't used to be. 05:43 Back in 1900, the amount of people 05:44 they need to glasses to see far, 05:47 at the ages of 15 and 25 were negligible. 05:50 I mean small percentages. 05:52 And now it's the majority of kids, 05:55 you know, between the ages of 15 and 25. 05:57 We're gonna need, they have corrective lenses 05:59 in order to be able to see far 06:01 or wear contact lenses or get the Lasik Surgery. 06:04 And there is actually more than one reason 06:06 it's not just their lack of exposure outdoor light. 06:08 In order words being indoors all day in school 06:11 and those types of things, 06:12 but also when they have light exposure at night. 06:17 Nightlights, for instance have been shown 06:19 to increase the risk of Myopia in kids. 06:22 And so it's better for them 06:23 to sleep in the dark environment 06:25 or to have very, very low lightning, 06:27 like moonlights okay. 06:29 But if it's anything greater than moonlight 06:32 it's going to decrease their melatonin levels 06:35 and that maybe associated 06:36 with that eye growing excessively 06:38 in Myopia development. 06:40 I know how to get the kids outside? 06:42 You buy them a little kitten 06:44 and you have the kids stay outside. There you go. 06:47 Just get one, and they are outside. 06:49 As soon as they get up 06:50 to see how the kitten is doing, 06:52 how the little kitties are doing 06:53 and they don't want to come in. 06:55 So if you want to try and get your kids outside, 06:56 besides from locking them outside, 06:58 get them small animal. 07:00 That study was from where? 07:02 That study was from the journal, 07:03 Ophthalmology in August of 2008. 07:07 Large waist, as they related to strokes. 07:11 In other words, I think you mean midline the waist. 07:14 Yes, and that has to do 07:17 with actual waist to hip measurements. 07:21 You know, we used to measure obesity 07:24 by stepping on a scale, 07:25 you know, if you're up 07:26 too many pounds now that was it. 07:28 But now we know the waist to hip ratio is even 07:32 more important than how many pounds you weigh. 07:34 And a large waist circumference 07:36 particularly in relationship to the hips 07:39 you have a significantly greater risk of stroke. 07:43 The waist to hip ratio is greater than 0.97. 07:46 You are significantly increase risk of stroke 07:50 and that's if you are man, 07:52 and if it's greater than 0.84 07:54 you are significantly increased risk of stroke 07:58 if you're a female. 08:00 And it turned out to be 7.69 times of risk. 08:04 I mean anything that doubles the risk is significant. 08:06 And if it's a 50 percent increase risk, 08:08 which is 1.5 times that's significant. 08:11 This was 7.69 times, 08:14 almost an eight fold increase risk in stroke. 08:17 Just as a result of having a high waist to hip ratio. 08:23 Now it turns out, increased waist circumference 08:26 also showed a strong association 08:28 with the precursor of stroke 08:30 and that is TIA 08:31 or Transient Ischemic Attack. 08:34 And if your waist circumference 08:35 is greater than 40 inches 08:36 and you are a man watch out. 08:38 You dramatically increase risk for stroke. 08:40 If it's greater than 34 inches 08:43 and you're a female increased risk for stroke. 08:46 And so and of course the less you are below that, 08:50 even the lower the risk 08:52 and so it's not just trying to get it to 39 inches 08:55 if you're a man, but try to get down there to the nice, 08:58 slim waistline and the same for female 09:02 and you'll certainly lower your risk of stroke. 09:04 So waist not what not, 09:05 or if you don't want a stroke don't have a big waist. 09:08 So, where was that's study from? 09:09 That study was from the journal Stroke, 09:11 published in July of 2008. 09:14 Okay, you know, we've looked, 09:15 you know, all the way from sexual transmitted diseases 09:17 to, you know, whatever it is more time outdoors 09:21 to what in without a age in a healthy way 09:24 in our last couple of minutes here. 09:26 Yes, and this was a study 09:27 from Great Britain, United Kingdom. 09:29 Finding suggests that lifestyle 09:31 and other modifiable factors can help counter 09:33 social disparities in health and longevity. 09:36 This study came from 10,000 09:39 London Civil Service workers, 09:41 was the 17 years study. 09:44 They were 44 years of age on average 09:46 and they were free of major diseases at the outset. 09:49 In fact, if they did have a major disease, 09:51 they couldn't be enrolled in the study. 09:53 And so with the 17 years study, 09:57 starting out at age 44 and healthy, 09:59 they took to look at several factors. 10:02 And 17 years later 10:03 they found only 13 percent of men 10:06 and 15 percent of women 10:08 were found to be successfully aging. 10:11 That means that they had no major illnesses 10:13 and they had good physical and mental functioning. 10:16 So not too many people are aged in a good way? 10:20 Yeah, and you know that's before retirement even. 10:22 And so lot of people that are 44 10:24 and healthy they think, 10:25 hey this is the way I'm gonna be, 10:26 they don't realize. 10:27 They have over an 80 percent chance 10:30 that they are not going to aged successfully 10:32 in the next 17 years. 10:34 And the odds of successful aging 10:36 depended to some degree in their social position. 10:40 But they also found it was independent of that, 10:43 particularly, if it was related 10:45 to lifestyle factors. 10:47 And the lifestyle factor 10:49 associated with healthy aging, 10:51 healthy diet, avoiding smoking, 10:53 getting regular physical exercise and social support. 11:00 Those four factors were related to successful aging 11:04 in a dramatically increased, 11:07 the likelihood of successful aging. 11:09 So have some friends go out and get on the move, 11:11 have so good food. 11:13 And probably one of the strongest ones 11:15 again those are the friends. 11:17 Strongest ones as the friends 11:18 and also not smoking, exercise and a healthy diet. 11:22 This was publish in the Journal of the American 11:23 Geriatrics Society, in June of 2008 11:27 and it was done by Dr. Annie Britton. 11:32 Well, Dr Nedley these studies, 11:33 you know, all of them that you have covered today 11:35 they are fascinating and of course 11:37 have a lot of take home value 11:38 depending on where you are. 11:40 And no matter what the situation you have, 11:43 you want to stop it and prevent it 11:44 or avoid those different things. 11:46 Thanks for doing this research 11:47 or brining actually the research 11:49 that you done to us today. 11:51 Yes, and it's my pleasure to doing so. 11:53 And thank you for joining us on Health For a Lifetime. 11:55 We know that's there's take home value today. 11:57 And on every episode we want you to come back 12:00 for another episode of Health For a Lifetime. |
