How To Clean Your Lungs

How often does the question ‘how to clean your lungs’ pop up? Not very often: even if it is a very important one. What is a lung cleanse? It involves a process that rids the pulmonary system of toxins. Unhealthy habits such as smoking and spending long periods in a polluted atmosphere can lead to the build up of toxins in the lungs. The lungs use their natural protective mechanism to shield the pulmonary system from these toxins by increasing the mucus cover. People like you who work in a dusty environment, those who live in extremely polluted cities and ex-smokers should definitely be asking the question how to clean your lungs?

Lung cleansing not only helps in detoxifying the pulmonary system, but also balances blood pressure, improves digestion and strengthens the body immunity system. Natural lung cleanse is very simple to follow. Simply breathing fresh air can help cleaning your lungs. If you are cooped up indoors, either at home or at your workplace, get out and get a dose of fresh air. If working in a dusty and polluted environment is unavoidable, try making frequent trips to a nearby place where you can breathe relatively clean air.

An effective way to get healthy lungs is practicing some form of sport or exercise. Cardiovascular exercises are great lung cleansing exercises.You can start with a thirty minute brisk walk and slowly increase your walking speed. If you have no physical complications such as a back or knee problem, then you can even try jogging and running. Cycling is also a good cardiovascular exercise.Swimming is also a great way to improve your respiratory capacity.

After your exercise, try and have a hot water bath. If you have access to a steam room or a sauna use it at least a few times a week for about 15 to 20 minutes. Doing these will stimulate perspiration and will help cleaning your lungs and pulmonary tract. To your lung detox exercise routine you can also add breathing exercises that strengthen your lungs. For instance, Pranayam which is a technique of breathing in yoga can go a long way in keeping your lungs healthy.

There are several home remedies for lungs Garlic and Lime being the simplest and ready accessible off the shelf in your very own kitchen and they should be consumed in small quantities every day. However, natural colon cleansing is recommended before starting the lung detox. For example, having natural herbal laxatives are beneficial. A tea with laxative properties can be consumed the night before you start your lung cleansing procedure. It is important to get rid of any kind of blockages such as constipation the body is suffering from before starting the process.

A natural colon cleansing diet is advised as well. This diet is rich in fiber. Foods such as apples, bananas, whole grains, vegetables, nuts, dried fruits and seed have high fiber content. The daily dose of fiber for an adult should ideally be around 40 grams. Similarly, drinking at least 2 liters of water daily would help in natural colon cleansing at home.

Some natural lung cleansers are grapefruit juice, carrot juice, potassium, ginger, peppermint and cranberry juice. Many of these are foods that help the proper digestion of alkalizing foods which in turn improve the functioning of the lungs. Lime juice can be had on an empty stomach as soon as you wake up. Next, you can have grapefruit juice with your breakfast. For your mid-morning snack have a tall glass of carrot juice. Carrot juice is high in beta-carotene which is transformed into Vitamin A. This gives a boost to your respiratory system. For lunch, try and have a good dose of potassium. Potassium is a good detox agent for the body. It can be found in green leafy vegetables and carrots. Finally before hitting the pillow cranberry juice can be had. This juice is known to cleanse the urine and blood and is has excellent antioxidant properties. These are the different lung cleansing foods that can be had on a regular basis and more so when you want to follow a lung cleasing schedule.

Similarly lung detoxification can be done with different herbs. Rosemary, Mullein, Lobeia, Black Cumin, Honeysuckle and Chrysanthemum are the most well known lung detox herbs. The consumption of these herbs however should not be done in a haphazard manner, since some of them can be harmful to the body in case of an overdose such as Lobelia. These herbs are essentially lung supporting..

Lung detox teas made from different herbs are also easily available. There is also tea for lung cleansing that is known to relieve congestion in the respiratory tract as also deal with bronchitis and colds. This will help soothe the irritated passages of the bronchial tubes and also clear the excess mucus in the lungs. Vitamin D is the supposedly the best lung detox vitamin. This is the same vitamin that is lacking in smokers.

If you want to follow a lung detox diet along with other home remedies, have a lot of cabbage, cauliflower, Brussels sprout and broccoli. Also eat those foods which are rich in beta carotene such as carrots, beetroot and sweet potatoes. High antioxidant foods should also be added to your diet; for instance, grapes, green tea and almonds. Foods rich in sulfur such as watercress and foods rich in Omega-3 fatty acids such as fish, organic butter and eggs must also be had in sufficient quantities.These natural lung remedies go a long way in safeguarding your pulmonary well-being.

As for a lung cleanse for smokers, the best option would be to give-up smoking completely. In non-smokers the lungs detoxify themselves naturally with the help of cilia which are minute hair-like particles that act like filter in the lungs. In case of smokers, the cilia get damaged over time. A natural lung cleanse for smokers merely signifies a lifestyle change.

How to clean your lungs after quitting smoking? When considering methods on how to clean your lungs after smoking, remember exercise is the key. Regular exercise, a well-balanced diet rich in antioxidants, vitamins, fiber and beta carotene and a will to never take up smoking again can help restore the health of your lungs.

Morphological changes of dust particles

Real-time evidence of morphological changes of dust particles due to internal mixing with pollution

Frequent occurrence of both anthropogenic pollution and natural dust in East Asia has great impact on regional air quality, human health and climate. Until now, their interaction and consequent effect on dust morphology remain statistically unclear, because even though the traditional filter-based bulk sampling method can provide accurate chemical compounds, it cannot distinguish the mixing state of chemicals with dust particles.

“Single-particle inspection using electro-microscopy can identify coated/contaminated dust particles,” says Dr. PAN Xiaole from Institute of Atmospheric Physics, “but real-time measurement on the morphological variation of dust particles was difficult due to labor-intensive manual operations.” In a recently published paper in Scientific Reports, PAN and his collaborators from China and Japan investigated polarization of the oscillation direction of the back-scattering signal of single dust particles online using a newly developed bench-top optical particle counter.

A real-time decrease in Asian dust depolarization was observed in North China for the first time. PAN reckons that it can only be caused by the decrease in the particle aspect ratio, which was reflected by the coating of an air pollutant, such as the deliquescent dust-nitrate Ca(NO3)2. “This phenomenon was obvious when the dust particles were stagnant in a polluted region with a high relative humidity condition,” says PAN. The statistics highlight the significant importance of internally mixed “quasi-spherical” Asian dust particles, which were more hygroscopic and likely to act as cloud condensation nuclei (CCN).

Because the NOx emission in East Asia has been rapidly increasing over the last decade, their findings imply that nitrate has become increasingly important on the morphological change of Asian dust and its subsequent spatial allocation.

“Nitrate plays a leading role in regional climate change,” PAN concludes. He adds, “Many processes associated with the direct/indirect effects of dust-nitrate are still insufficiently understood, and this requires more attention from the public and poses another challenge for the observation and modeling communities.”

Their findings have been published and online in Scientific Reports.

An energy-efficient cleaning robot

State-of-the-art solar cells are efficient – but are even more so when they are kept clean. A cleaning robot developed by Norwegian researchers enables solar panels to deliver at full capacity.
An energy-efficient cleaning robot

At a solar energy farm just outside Budapest in Hungary, a cleaning robot is industriously getting on with today’s task. Hundreds of square metres of solar panels are waiting to be cleaned – as quickly and effectively as possible. And without the use of chemicals or any unwanted discharges to the natural environment. The robot is the result of a joint project between Norwegian researchers and the Hungarian company ProDSP Technology.

“It’s a well known fact that solar panels work more efficiently when they’re clean,” says SINTEF researcher and Project Manager Martin Bellmann who, in his day-to-day work, develops what is known as sustainable energy technology. “But what’s new here is that we’ve developed a robot to do the job. This means that the solar are cleaned both quickly and efficiently with as little as possible wear and tear or environmental impact,” he says.

There’s dirt and there’s dirt

Cleaning solar cells using a robot may sound like a straightforward job – but there’s dirt and there’s dirt. And when a solar farm covering several square kilometres is being cleaned, no chemicals can be used, and there must be no damage to the natural environment. So how do we get to grips with a challenge like this?

Solar cell researcher Birgit Ryningen is examining a set of glass plates in SINTEF’s Daylight Laboratory. They are all contaminated to order, but in different degrees.

The reason is that the dirt in question has been precisely applied. These plates will now be studied in detail by researchers in order to provide answers about how much the contamination occludes sunlight. This is the final phase of the project.

There really are all kinds of dirt. “The degree to which dust particles and contamination affects solar cells is very location-dependent,” explains Ryningen.

At the start of the project she carried out a literature study to find out how such dirt affected its surroundings, only to find out that existing research focusing on air pollution and dust particles had for the most part been directed on the human body. However, she did find examples of research into the ways in which sand storms impact on solar cells installed in the Middle East. In other words, more research was needed in order to provide scientists with more details about this subject.

“We’ve seen that some dust particles absorb light while others reflect it,” says Ryningen. “And small particles reflect more light than larger ones, whereas some scale contamination is biological and acts as a kind of ‘sun factor’,” she says. And some scale coatings are thicker than others.

However, what they all have in common is that they must be removed in order for the solar cells to function optimally according to specifications. For this reason, the researchers have developed a cleaning approach that is both fast and sensitive, as well as being environmentally-friendly. And which can deal with all the different types of contamination we encounter.

Cleaning is part of normal operations

The Norwegian company Scatec Solar constructs, owns, operates and maintains solar energy farms in many countries, including the Czech Republic, South Africa, Rwanda, Honduras and Jordan. Last year, the company’s sites generated as much as 791 GWh. This is equivalent to the consumption of 200,000 average EU households.

Project Manager Caroline Sissener at Scatec Solar describes the Norwegian researchers’ solution as interesting, especially for solar energy farms located in the Middle East.

“Cleaning is part of standard operational procedures at our solar energy farms, where equipment is cleaned at least once or twice a year on order to avoid soiling. This involves the removal of everything from sand to bird droppings ,” she says. “But cleaning frequency is location-dependent. If a farm is located in a desert environment, the panels will require more frequent cleaning because the solar cells become covered with soil and sand,” says Sissener.

She goes on to say that Scatec Solar often employs manual cleaning methods because these are effective and inexpensive, but that the company also uses automated systems.

“Cleaning robots may offer a relevant and attractive solution for solar energy parks located in areas where frequent cleaning is required,” says Sissener.

She also informs us that manual methods are important to Scatec in some situations because they provide local jobs. The method chosen is assessed on a case-by-case basis, and environmental factors such as water shortages and neighbouring agricultural activity are also taken into account.

Robot arm and micro-showers

The robot cleaner currently in SINTEF’s laboratory has undergone a range of tests. Researchers have experimented with a variety of micro cleaning pads, chemicals and air pressure application approaches – all tested, of course, on different types of soiling.

“It is vitally important that we don’t discharge chemical pollutants into the environment,” explains Ryningen. “So we’ve rejected the use of traditional cleaning agents and have ended up using unbelievably small micro-droplets of water that are “sprayed” onto the glass, almost as a vapour. Then the robot uses a micro cleaning pad that effectively removes the contaminant particles.

Because solar cells can be exposed to wear and tear, researchers have also been working hard to develop methods of controlling the pressure exerted by the robot’s cleaning arm.

“It is vital that the robot doesn’t scratch the sensitive glass surface. Even small scratches can reduce the efficiency of the solar cells,” explains Ryningen, adding that “in theory, this should work on windows as well, which will open up a broader market for us,” she says.

Negev desert solar field uses water-free robotic cleaning system

At large solar plants, keeping surfaces of solar panels free from dust and sand is not just a matter of good housekeeping but of whether or not the plants can really make a difference to the communities they want to serve. In other words, keeping the panels clean especially in very dry areas may be a matter of solar plant effectiveness or ineffectiveness. Solar plant panels in deserts collect large quantities of dust. Recently, a solar park in Israel was provided with an answer to the problem.

The 20-acre Ketura Sun Solar Park in the Negev Desert (located in the hot southern stretch, which suffers from sandstorms and little rain) was introduced to a robotic cleaning process from an Israel-based company, Ecoppia. No water is needed for the cleanups. Instead, each night (cleaning typically takes place during the early hours of dark) 100 centrally controlled E4 robots, as they are called, go to work on the panels using microfibers and controlled air flow to push dirt off panels. The robots use gravitation to move the dust particles downwards and off the panels. They move along a rigid aluminum frame with wheels coated with polyurethane; there is no load on the solar panels’ surface.

Ecoppia designed the system to be water-free and energy-efficient. When not cleaning, the robots are locked to a docking station outside of the solar PV row. While docking, robot batteries are charged through their solar panel. The fleet can be remotely managed from a dashboard or mobile app.

Before the latest robotic cleaning process, Ketura Sun’s solar panels were only cleaned about nine times a year, in consideration of the expense involved in a labor-intensive, water-based cleaning process. Manual panel cleaning could take up to five days. As a result operations worked suboptimally and in the interim between cleaning cycles the park suffered electricity production degradation due to “soiling,” the term used to describe the accumulation of dirt and dust on photovoltaic solar panel surfaces.

Ecoppia, founded in 2013, is in the business of photovoltaic solar panel cleaning solutions The Ketura Sun solar park is jointly owned by Siemens AG and solar energy pioneer Arava Power. Founded in 2006, Arava Power has seven solar parks in production or development across the Negev, with a total production capacity of 80 MW. In 2009, Siemens AG acquired a 40 percent stake in Arava Power.

The park’s robot cleaning crew is yet another marker of interest by the solar industry in improved techniques for keeping panels clean and efficient. Last November, a Tokyo-based company, Sinfonia Technology, announced it developed a robot with camera and sensors that can move autonomously and clean solar panels at large-scale solar power plants. Its robot had another approach, with equipment including scrub brush, wiper and detergent; and sprinkling water stored in its tank.

Also in November, US-based SunPower announced the acquisition of Greenbotics, a company with panel cleaning products for large-scale solar power plants.
