strong thoughts of particulate matter ships especially in times of covert 90. they might be docked but that engines are still burning cruise ships here in hamburg and another courts around the world. they're likely to remain in place until the pandemic is over. the menu and cause of the number of cruise ships here means a lot of pollution in the cities that's affecting people's health. and one of them and one of the feet of. air pollution is also a major focus for corona virus researchers they want to find out why mortality rates vary widely across different regions. they suspect that dirty air leads to more people dying of covert 19. researches compared data from the european space agency satellite sentinel 5 about

nitrogen oxide levels in the atmosphere with 19 mortality figures. they found that in areas where the nitrogen oxide level was very high the cove at 19 death rate was as well. nitrogen oxide emissions tend to occur in the same contexts where particular matter and other pollutants are released farming industry and transportation cardiologist thomas minutes all studies the health impacts of particular matter. we know that particular matter ranges in size between 0 point one micro meters so about the size of a virus particle it seems that the smaller a particle is the more dangerous it is because he only goes on. such particles and to the body every time we prefer. the larger ones are intercepted by miniscule has and mucus in the respect which attracts and expelled.

smaller particles make it into the lungs and can cause inflammation. from the lungs they can also go into the bloodstream. so that it causes inflammation in the long term particulate matter can lead to vessel or calcification high blood pressure there owing of the corona re arteries of the heart attacks and strokes. specifically it can cause inflammation of the end of the layer of cells that line the interior of blood vessels. studies have shown that the song to virus also attacks the end with elian . in severe cases of 19 acute inflammation can lead to heart failure and other organ damage. too right now we have patients who have been exposed to high levels of air pollution for decades and have

a severely altered vascular system coronary heart disease and heart failure in the virus comes along and causes further damage to the blood vessels and so we have to reckon with significant excess mortality in such patients over the age of 60 people say the harvard. professor says the intense pollution of the past decades is taking its toll on its make many people sick and they're now more susceptible to severe forms of that 19. data from the sars outbreak in 2003 reveal a similar patent regions with higher levels of pollution so high in mortality rates . a shot for an industrial production and transportation sharing kovac $1000.00 lockdowns sowers a cline an appalachian last year at least for a while but diesel engines on board $400.00 cruise ships around the world are still running even while in harbor. they have to power the electronics so they keep

spewing particular matter. less than when the ship's amusing but certainly enough to harm the environment. because of even while that dog cruise ships need a lot of electricity and they generated by burning fossil fuel much dirty a car and then cars and trucks use what's more most ships have no catalytic converters of particle flightless so they causing far worse a pollution than vehicles on the road it's a much reduced cost for. the world health organization recommends reducing levels of particular matter in the $210.00 micrograms per cubic meter. sloshing appellation is key to public health while white. not only particulate matter is transmitted by you but also aerosols small liquid droplets one of the pathways they never corona virus is transmitted through the

community air as old appeared used by humans when their cuff they laugh they talk and when they sing. i. singing for science a soprano from the berlin cathedral choir and an engineer from the technical university of berlin are on the search for air assaults. c. this device captures the invisible aerosols the flying out of the singer's smell. the microscopic particles are then counted if she were infected with corona these aerosols could spread the virus. he said i don't have as the main thing we're trying to do is determine how many aerosols people emit in different situations whether they're singing speaking or just breathing without information we can estimate how much one person can impact an entire room and how high the infection

risk is for others in the same space. as. theatrical fog is being used by the engineers at the technical university of berlin to imitate the behavior of aerosols the experiment reveals potential dangers caught in distrust in the most spaces with no way circulation it's possible for a person who comes into a room minutes after another person is already left to be infected by the cloud of aerosols the 1st person left behind it's proven that these airborne aerosols contain enough of the virus to infect others. even in an office with standard ventilation like the one in this experiment virus laden aerosols quickly spread throughout the room and i think it goes on and if there's one person in a large well ventilated room then the risk of infection is minimal and if i have a small office with 2 people in it and one of them is infected then the risk to the other person is very high and most cases. devices like this measure the c

o 2 level in a room if it goes up indicating that many people have been exhaling there could be virus containing particles in the air. you can only try to lower the risk by reducing the concentration of aerosols in the air as much as possible and by having a high proportion of fresh air via proper ventilation the 2nd factor is duration how long should i stay in a given room the answer is as briefly as possible. after a rehearsal last march almost every member of the berlin cathedral choir contract a covert 19. now they're singing is helping researchers find answers to the many open questions about the coronavirus. in good shape your weekly health show on d w covers many aspects of health care. we look at what's new in medical treatment nutrition fitness and beauty. we talk about these topics

in depth with experts and give you the chance to pose your own questions so do get in touch. what else is in the the weather but whether it's cold or hot all rainy or dry it can make us sick. will it be sunny right any snowy all windy the ever changing weather that can literally be a headache for some people. others report fatigue or dizziness. how can the weather have such an impact on us. that the food the weather sensitivity is not so much in the race it's proven to exist until a chute knows all about al bodies and minds reaction to the weather. i'm give it a foot in the hole and it's above all the changes in the weather that have this discomforting effect by a certain symptoms. and. this is mainly due to the thermal

factors he cold and humidity the feeling of him and the impact on the skin vessels. and the how to give and this gets the circulation activated. activia. while many weather sensitive individuals feel mild symptoms others feel the changes much more severely. than taking fainting fits i think whether sensitive refers to those people who have a particular illness and then see their symptoms westerling under certain weather conditions for example people with reluctant disorders. people who suffer from rheumatism often find it hard to explain the fluctuations in the pains they're experiencing at some point some notice that it's the weather. it's an issue that meteorologists have now also started looking at. and real smart so doctors from the

german weather service can forecast potential health issues on the basis of the weather. they are after i live in a suit or 2 on the incoming weather situation will be cooler with a cold front moving very slowly and. some so that means in the very or tomorrow we can expect an increase in asthma related problems as well as cardiovascular and rheumatic symptoms. what you're waiting with there and most pressure fronts are bad news for weather sensitive people for those experiencing acute pain heat and relaxation can provide relief. but as always it depends on the individual a trip to the sound or a hot. cold water treatment could also help although experts do say brave the elements to steel their resistance while also adapting our bodies to future

fluctuations in the weather. that's a photo they see again next weekend and so then let's all try to stay in good shape . in.
