Perfumes and Paints Are Polluting…

Scientists have found that everyday household products, like soaps, paints and perfumes are causing nearly as much air pollution as cars and industries combined.

Most air pollutants come from the extraction, refining and use of fossil fuels. These pollutants include hundreds of different compounds that scientists clump into what they call Volatile Organic Compounds (VOCs). “Once they’re emitted into the atmosphere, they can lead to the formation of ground level ozone and particles, both of which are detrimental to human health,” says Jessica Gilman, an atmospheric chemist at the U.S. National Oceanic and Atmospheric Administration (NOAA) and an author of the new study. However, in recent years household products have become a bigger source of air pollution, the team reports in today’s issue of the journal, Science.

They made similar observations for isopropanol, or rubbing alcohol, and acetone, the main ingredient in nail polish remover, and a whole range of other chemicals in everyday products like soaps, wall paint, printer ink, perfumes and pesticides.

The findings are important and surprising, says Albert Presto, an atmospheric scientist at Carnegie Mellon University. “We’re all conditioned to think about traffic and industry as the big drivers for air pollution and pollutants. And this study says, ‘wait a minute, a lot of it is really stuff we’re using inside our homes.'”

These household sources have emerged as big polluters because cars have become cleaner, says Jonathan Levy, an environmental health expert at Boston University. “As traffic sources decline, other sources become more and more important over time.”

Air pollution remains one of the top causes for the burden of disease worldwide. “Ozone can do things like worsen asthma, trigger asthma attacks,” says Janice Nolen, the assistant vice president of national policy at the American Lung Association. “It can also kill people, it can shorten lives.” Exposure to particulate matter has similar deleterious health effects.

So, the new study has implications for further reducing air pollution, says Presto, especially for cities that are struggling with meeting air pollution standards, like Los Angeles, which has one of the highest levels of ozone in the country. “You can only make cars so clean,” he says. “Maybe the way to get ozone below federal limits is to reduce emissions from indoors.”

The new study suggest we need “some national measures to help reduce emissions” from these everyday sources, says Nolen.

Death through medical oxygen, But what are the dangers of medical oxygen?

Danger

The benefits of oxygen can be felt by anyone, not just those suffering from a medical condition and requiring supplemental oxygen. We can all find easy ways to increase our oxygen levels naturally through breathing exercises, general exercise, getting more fresh air and eating a balanced diet of foods that help increase oxygenation in our blood.

Increasing your oxygenation levels and being fit and healthy has shown to be important for your health as optimum oxygen levels can improve wound healing, vision, mental clarity and intelligence, boost your immune system, help fight cancer cells, reduce stress levels, improve your heart and respiration and help you to lose weight.

For those people who use supplemental oxygen at home there are also long-term benefits:

  • Prolongs life by reducing heart strain
  • Decreases shortness of breath
  • Makes exercise more tolerable
  • Results in fewer days of hospitalization
  • Improves sleeping
  • Improves quality of life

There are millions of people diagnosed with COPD around the world and 15% of these are prescribed oxygen. The number of COPD patients coming into the market is increasing and is expected to continue to increase for many more years. COPD patients are also increasingly being prescribed oxygen until the end of their life expectancy combined with the fact that COPD is being diagnosed earlier in life due to an increased awareness of the condition means that many more people will be requiring oxygen for longer periods of time.

For those people who suffer with any type of lung condition they may have difficulties when travelling by air. This is due to the reduced air pressure in the aircraft cabins as well as the lack of mobility for long periods of time. Air pressure in an aircraft cabin is lower than air pressure at ground level and feels like being at 6000 to 8000 feet on a mountain. At high altitudes blood oxygen levels fall in everyone, and some people may feel a little breathless. In most people this has no health effect, but if you already have low blood oxygen levels because of your lung condition, then the extra dip that happens while you are in the plane can cause breathlessness and discomfort for you.

Essential Tips to remember before flying:

  1. Ask your doctor well in advance for a letter to take in your hand luggage with details of your condition and medication.
  2. Be sure to take your inhalers in your carry-on bags. One of the most common problems is that people pack their inhalers in the luggage that goes into the hold.
  3. If you get breathless when walking, make sure you have help at airports.
  4. Try to move about every hour. Sitting for too long can lead to blood clots in the legs.
  5. Drink plenty of water and non-alcoholic drinks during the flight..

At OxygenWorldwide we wanted to know if in our 25 years of existence with oxygen users had died from the use of medical oxygen. We are glad to state that we have not found any proof of death related to the use of medical oxygen.

 

Eczema reduces asthma

Researchers have found a possible new therapy for eczema that also helps reduce the severity of asthma.

According to the researchers, children with atopic dermatitis (AD) – a type of eczema of the skin – show an increased risk of developing asthma later in life.

The researchers also mentioned that house dust mites are known culprits in the development of both atopic dermatitis and asthma, as exposure to the mites induces inflammation.

“The treatment did significantly reduce the severity of the asthma by counteracting one aspect of the specific immune response in the lungs. In this way, the therapy represents a potent remedy against allergic skin inflammation and the aggravation of atopic march,” the researcher noted.
The findings are an important next step in understanding the relationship between the two inflammatory diseases and to developing effective therapies. – IANS

Are women fitter than men?

A new study shows that when women exercise, their body processes oxygen a lot faster than men’s. This indicates superior aerobic fitness, explain the researchers. In other words, women may be naturally fitter than men.

man and woman ready for running

But new research challenges the traditional belief that men are athletically superior to women. In fact, by measuring women’s response to aerobic training, a new study suggests that the opposite may be true.

The new study examined sex differences in the body’s response to aerobic fitness; more specifically, it focused on how sex affects the body’s ability to process oxygen once it starts to exercise.

Thomas Beltrame, from the University of Waterloo in Canada, led the research, and the findings were published in the journal Applied Physiology, Nutrition, and Metabolism.

 

Oxygen uptake is a standard measure of aerobic fitness, and it describes the amount of oxygen that the body can take in and use per minute.

As the American College of Sports Medicine explain, our oxygen consumption rate “provides a measure of the maximal ability to perform high-intensity aerobic work, [and] is strongly associated with performance and health.”

Therefore, a higher rate of oxygen processing means that women may be less prone to muscle fatigue and more likely to perform better athletically. They may also be more resilient, as higher oxygen processing also indicates a lower perception of physical effort.

“The findings are contrary to the popular assumption that men’s bodies are more naturally athletic,” Beltrame says.

Oxygen therapy treat Alzheimer’s?

Breathing oxygen at a higher-than-normal air pressure might ease some of the symptoms of Alzheimer’s disease, if recent research done in mice has the same results in humans.

Mice genetically engineered to develop some human features of Alzheimer’s disease showed significant reductions in physical and behavioral symptoms after 2 weeks of daily treatment with hyperbaric oxygen therapy (HBOT).

This was the result that a team hailing from the University of Tel Aviv (TAU) in Israel reported in a paper that was published recently in the journal Neurobiology of Aging.

HBOT is a type of treatment during which the person breathes oxygen at a pressure that is greater than normal air pressure. The treatment, which is delivered inside a pressurized chamber, can cause the lungs to absorb up to three times more oxygen than usual.

The researchers note in their study paper that, while HBOT “has been used successfully to treat several neurological conditions,” its effects on Alzheimer’s disease “have never been thoroughly examined.”

In a hyperbaric oxygen chamber that they custom-built for the small animals, the researchers gave the transgenic mice 1 hour of HBOT every day for 14 days. They also gave another group of normal mice (the controls) the same treatment.

After this, the team observed the mice as they completed a number of behavioral tests. They also examined their brain tissue for effects of the treatment on the physical hallmarks of Alzheimer’s. They compared the results with the control mice.

The researchers’ analysis showed various biological and biochemical signs that HBOT had reduced inflammation in the brain.

 

The team suggests that the findings show that HBOT shows promise as a treatment for Alzheimer’s disease, especially given that it “is used in the clinic to treat various indications, including neurological conditions.”
