ah, discover the world around you. subscribe to d w documentary on youtube. b . this week d, w is health, so focuses on our heart and circulatory system. sometimes less complicated, network goes wrong. some people suffer from low blood pressure or a congenital heart problem. most people are born with a healthy cardiovascular system, but beating too much fat or salt all being obese can lead to problems. as can smoking, getting stressed out or not exercising enough. hello and welcome to this leaks in

good shape. with your kids like to describe their transit system as the life blood of the city like our bloodstream, the rail and road network supply the big apple with what it needs but compared to the human circulatory system. new york transport system is laughably tiny, while it subways only measure a total of 400 kilometers. our veins are 100000 kilometers in length. that's the equivalent of circum navigating the earth almost 3 times. during the show, your heart will have pump some, 13 buckets full of blood through that system. so our veins are constantly under pressure and sometimes the pressure gets too strong. your overall of blood pressure

is measured by 2 readings. mild hypertension begins that a reading of a $140.00 a $170.00 over a $105.00 is in the moderate range. that's the reading level heater has just measured. but what are the different values mean? the number 170 is the static pressure and a 105 is diastolic. so the numbers represent different values. systolic is the value in the pumps. diastolic is when the heart relaxes. so does peter know why he has hypertension? ah, blood vessels play essential role. tension can cause the vessels, muscular wolves to contract, narrowing them and increased hartwright can cause this. an innovated, hartwright is a natural response to danger, to increase physical capacity temporarily fight or flight whole. when highly stressed,

our sense of pain is don't. these responses repeat is a bible in the history of human evolution. but in the modern world, the fight or flight mode is really a suitable reaction. and if chronic this bodily reaction becomes harmful, it can trigger a range of health issues on bone. high blood pressure strains, the wools of the vessels damaged blood vessels increased the risk of vascular occlusion, or a blockage of blood flow. in the brain, vascular occasion can cause a life threatening stroke. in the heart, a clot can cut off the blood supply and cause a heart attack. but even if it doesn't lead to a heart attack, high blood pressure is bad for our heart. pumping blood becomes more difficult, the heart muscle hardens. hypertension also strains other organs,

the kidneys in particular, no longer function properly. and it doesn't, and their delicate veins at the back of our eyes are sensitive to high pressure. it reduces the blood supply to the retina. this leads to impaired vision. medication can be used to treat high blood pressure with 3 main mechanisms. a c, e in have it is with the tension in the blood vessels. visa block is reduce cardiac outputs. and diuretics with their dehydrating effect, reduce the pressure on the blood vessels. it's a common health issue. only one in 10 people with hypertension achieves a normal blood pressure range on these medications. lifestyle changes a more effective high blood pressure can be treated with various drugs. but they are often of limited help and come with side effects. but

you can help yourself. you should lose some weight if you too heavy with exercise and the right food, if possible. regulate endurance training is best, but don't ever do it if you go for a run, make sure you can still chat. capital strength training also helps curb high blood pressure at best with an experienced coat. eat more fresh fruits and veggies and healthy fats and go easy on the salt garlic, watermelon, and beats. ah, comforts like these really lower up blood pressure. in to find out, we scoured medical data banks for studies and found many that examined the effects various foods, half on blood pressure. all of these studies followed the same basic principle

we take beat use, for example, a test passions were selected who fast their initial values, but determined body fact unplugged values as well as upper and lower blood pressure readings to make subsequent changes visible. oh, beat juice is of particular interest to researchers. beats naturally contain nitrate or n o 3, which can influence blood pressure. ringback ringback ringback so precisely, this substance was removed from the 2nd sample of beach juice given as a placebo, to a control group. oh, hello them, fatty. yes. such tests have been conducted on beats, watermelon and garlic. and the results are always the same. all 3 have been shown to low blood pressure. it's a minor miracle, but one that's too little known. so we consulted

a nutritional scientist. i heem, bob is researching whether feeds could even replace drugs when treating high blood pressure. gone as it, it's quite interesting because we intervene with foodstuffs in so you could say, we'll treat people with food and at work sequences neatly. of course, not to the extent that it does with medications, but in small steps, maybe come in and eat, and maybe putting a lot of little steps together. we will produce a big one among kenneth, off and inclusive and game. how should we consume beats, for example, here the active ingredient is night trait. so wouldn't a nitrate extract be the simplest way? couldn't said lee sickly. it's better to consume whole foods than single isolated substances isolated salinas, which hadn't in his co because complex foods have many more mutually beneficial components which serve additional functions in the body for all but on. oh,

so said sequel to form to one beat. a whole melon, several cloves of garlic, or hopefully to have beat juice per day, really did hope to lower the test person's blood pressure. but you consume such mass quantities in real life. you can drink 2 or 3 leaders of beatrice a day if you did. i can't expect that of any one motor feed base or it is. it's much better to consume a variety of planning based foods as part of a changed diet or lifestyle homes. would al clayton's wiser, using this to achieve a normal weight and can gets rid of the cause upon with blood pressure. if at the same time he 70 to 80 percent of all patients with high blood pressure arrived wait and there were limits to will even see profits contained so a healthy and balance diet is still your best option. and

high blood pressure can be deadly. it's often called the silent killer as he may show no symptoms. unlike low blood pressure, pre menopausal women and young people are more likely to get it. the world health organization says for men, blood pressure under $110.00 over 70 is regarded as low. for women it's one of it over 60. ready old cardiologist both lun messy explains what we can do to feel better when we have low blood pressure. but how do we know we have low blood pressure in the 1st place? these m tormented symptoms associated with low blood pressure. they are being more prone to dizziness would what we call visa vega, reaction eisenberg, that is, if you get into a situation where the air is bad, where maybe it's very hard to say you're more likely to experience dizziness or in

the worst case a brief loss of consciousness i if the air is too hot of stifling, open the window and have a drink of water to people with low blood pressure, often feel faint when they stand up too quickly. why does that happen? when realtors are once asked him that when we go from sitting to standing, lud sinks to the lower part of the body and the vessels have to contracting. if he's in mrs. hammond see this bees, the nerves must react and regulate the vessels to accommodate the new situation there. and if this reaction is delayed, it can cause discomfort when candice at so which we had food. is that what we always recommend in such a situation is to get up slowly. not like a rocket and give the body some time to get used to the new situation and covered side dish and the noise address. once a government,

low blood pressure can also be the result of a serious illness. when should you consult a doctor? dance can see it very, very rarely. there are diseases from that. for example, an endocrinologist, order of the adrenal glands, known as addison's disease or disease of the thyroid gland, which can be associated with low blood pressure or, but that's extremely rare. as it's much more common that young people simply haven't elastic vascular system, it and therefore very low blood pressure, which is normally associated with a very good life expectancy about on for one. if you are healthy and still have low blood pressure, here's our experts advice. i said, in my opinion, we always recommend regular physical activity, which trains the circulation yet alternating hot and cold showers is also a way to train the circulation. make sure to drink enough, and especially in situations where the air is bad and core, you're exposed to heat. either just avoid such situations or just sit down in time

. so nothing bad happens and he does, or he's got sued mine or does he? but i said to him that some of them, it's even worth shipping. and if you find a physical activity that you find fun, even singing can raise your blood pressure. and some say drinks like tea and coffee also helped to get the circulation going through as far as special drinks go. and i think you have to figure out what works for you. like coffee can be helpful. for example, i don't see any health problems with coffee in that respect. it's something good to do that. coffee kind kind over to him in the finances and as a hobby man, just good mankind. and what about alcohol? gramma secret recipe for a low blood pressure. a glass of champagne on a regular basis is that advisable? female female doctors we always recommend avoiding alcohol,

but i also don't think alcohol can help keep your blood pressure up. yoga has been proven to be better than champagne, by the way, having low blood pressure, all your life doesn't protect you from getting high blood pressure in old age. so have regular checkups. here again are all flat messrs. tips to combat low blood pressure, physical activity, showers, alternating warm and cold water limit, alcohol, drink plenty of water. do you have a question about your health on the attrition? well being. all new treatments. thank just email us and our medical experts will go looking for answers in our digital office allies and now for our digital consultation, whatever in good shape you is want to know our experts are there to answer your question. veronica from zambia asks what are the signs

of heart disease? i would say there are 3 to advocate symptoms, venice or if you have a loss of exercise capacity or no on exertion, they deserve to pick a symptom of either heart disease or lung disease, but frequently of heart disease. the 2nd typical symptom for heart disease is chest pain. if this comes very acute one has to sink to a heart attack and we recommend to call a mutant d the emergency service. um, if it's more chronic, so you have it on excess on exertion, then we talk about chronic and gena pictures. and it is often caused by not sufficient blood supply to the heart because of no rings of the artery of the heart . the 3rd or typical symptoms of heart disease or heart rhythm disorders. and this

is you notice if their heart is too fast or too snow or is irregular to risk of getting heart disease increases when you have high blood pressure. but other fact is also play a role, for example, increased belief that when women's waste measure more than 80 centimeters and mens over 90 for poor if you have too much sugar. okay, lester in your blood. if everything is normal you have little severe. sometimes however young and apparently fit people get heart problems. you can't tell by looking at her, but can't alina kaiser has a serious heart condition? and only 31 years old? just 5 years ago, she felt perfectly healthy. one afternoon, she was visiting her parents and out of nowhere she suddenly lost consciousness. katerina herself thought the whole thing was poor circulation outside fish and

having mamma, in fact are my mom called the ambulance. i was kept on it. she already recognized the symptom noise because she had taken a 1st aid course for quote, if we had waited any longer, i probably wouldn't be here right for time with me for the diagnosis was heart failure or cardiac insufficiency. what is heart failure? a healthy heart works in 2 phases in this historic phase. ready the heart muscle contracts. ready oh, during that process blind is pumped out of the heart and into the body. ready in the diastolic or relaxation face, the heart muscle, relaxers and blood then flows back into the heart chambers. ready in heart failure, however, the heart can no longer pump properly. ready ready ready ready ready ready ready

ready professor england kent m on is a heart failure. ready specialist. ready ready ready businesses or does it say that there are a table 3 main causes of heart failure funding? first and foremost is high blood pressure, which can go unrecognized an untreated for years to hoist. so i'm a hobbs versus baton coronary heart disease. for example, very often lead to heart failure to help us does atherosclerosis of the coronary vessels, which can also lead to a heart attack. i'm house and fox flu encounter lena kaiser's case. none of those causes could be identified, but the doctor knows that the predisposition runs in her family. her father also suffers from heart failure. how can he recognize heart failure? by the beginning and how to push him back depos a own set of hot failure. patience usually notice shortness of breath under

exertion before her game con. the says that they could previously go up easily. now making short of bra who calmed her. in addition, there's a demon i'd want to retention in the lower lagoon. i need to put st. max on patients also notice an increase in thy waste measurement for vasa, that has to do with water being stored in the optima doesn't i think those are the signs of hot failure. hudson's wasn't since catalina kaiser didn't initially interpret her symptoms that way, which is why her heart was already severely weakened when she was admitted to the hospital. how do you live with heart failure? oh, forget up, we'll take your blood pressure right away. that's a horse. patience with heart failure come to her by cona, hama is a physician's assistant with additional training. anyone suffering from heart failure needs to be examined regularly, take medication and adjust their lifestyle from enough exercise to dial. foods

containing lots of water and salt should be reduced. saturated fats are also not good for the heart. ready that's why kola hama advises her patients to eat foods with omega 3 fatty acids and a diet rich and vegetables. in general, if you eat a healthy diet, exercise regularly and don't smoke, you can protect yourself from heart failure and not hospice. in the case of cardiac arrest, a defibrillator is often a lifesaver. it sends an electrical shock to the hot and gets going again, because i hans function electrically. but what about the electromagnetic field surrounding us? smartphones, microwaves, or electric cables are everywhere. do they influence a hans scientific studies suggest not the could e cause with that powerful engines and heavy batteries?

pose a health threat. electric and magnetic fields. give off radiation anywhere there's electricity. and the stronger the current, the stronger the fields and electric cars, full of electrical devices. and the strongest fields are the cables that one to and from the electric motor and connect to the battery. they mainly generate magnetic fields with low or intermediate frequencies. zod, theresa, a scientist who's worked at the research center for a bio electromagnetic interaction for the past 18 years, is researching the potential effects of magnetic fields on humans. need a high command, low and intermediate frequencies can stimulate things like muscles or nerves, or they can cause what's known as false deal, which is basically flickering light in the eye. often described as seeing stars because they are in very strong fields. dramatic effects,

such as ventricular fibrillation or muscle twitching can occur them on order off. most good silicone touchless, the cause magnetic waves penetrate the human body and produce what is known as eddy currents. they can disrupt nerve and muscle cells which are sensitive to electrical impulses. and method on to prevent this, we have specific threshold. so these acute effects don't occur. michelle clayton adherence to these thresholds is verified in a special lab. the measurements must be exact. so the testing station is completely sealed off inside it's lined with special light absorbers to prevent unwanted reflections. these measurements help car developers reduce radiation such protective measures mean exposure to magnetic fields is so minimal. they have no

impact on nerve and muscle cells. it's different in the case of implants such as pacemakers or defibrillators which are quite sensitive to electromagnetic or 80 current fields blue. so doctor carsten renounced from the german heart center in munich, asked 108 of his patients to drive an electric car for a study. they were medically supervised and drove on a chassis dynamometer that simulated realistic conditions. oh, we don't have tom. neither one driving electric cars, nor charging them did we see any impairment of function as far as the cardiac rhythm implants were concerned. that's quite encouraging was it means our patients don't need to worry. of the research team measured the most powerful fields, not while driving. but when charging the car directly with a cable, it's good the summer, the critical moment is when charging the vehicle,

considering the new charging systems come down to the mach had, have far greater charging capacity. this needs to be tested again, but for now i tell patients it's safe to drive like to cause whether you have an implant or not electric cars. amid so little radiation, there should be no negative health effects, at least in the short term potential long term ones. are still being studied needed in because of course, besides the known acute effects in the lower and intermediate frequencies are long term and perhaps chronic effects are being discussed. that is in the low frequencies above all, childhood leukemia. he cannot annoy kidney the w h o classifies elf or extremely low frequency, magnetic fields like those under high voltage power lines as potentially cancer causing in children. and that applies to radiation clearly below the limit values. but recent things, such studies have little relevance when it comes to electric cars,

as do backed back, i've been applying the results to electric cars. it's difficult because in the childhood leukemia study, it was almost entirely about 24 hour exposure, or at least being exposed to these fields for standard periods of time of year long . didn't said analysis at this, for used turkish rent. there has been studying the possible side effects of electromagnetic fields. he thinks there is still not enough research to provide clear answers. this is also, it's also important to know that the evidence comes from observational studies, which haven't been supported by experiments. so causal relationship hasn't yet been proven, though so far we can exclude it with sufficient certainty. that's why we basically recommend keeping an eye on every field strife. even hitched efforts off. the electric cars tested remained far below the european limit values for magnetic fields. that's the 1st all clear sign, but more studies are needed to know whether the new technology is truly safe for

everyone. exercise is the best thing you can do for your hot, his althea with a new look at an old classic hi . to day we train push up, so you just go on your met. hence, below your shoulders. then you go to on your fits, then your chest is moving to the floor and then you push up again, down and up. if that's a problem, no problem at all. we go on our knees and then we do exactly the same. so you go down and push up your arms or next to your chest. with trend your shoulders, your chest, your stomach,

and of course your you should do just as many reps as you can. so i can do maybe to read next week i just try to increase my ribs. so i tried to dupe 3. and that was in good shape for now. please join us again. next week. i will ah, with
