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.
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.
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.”
The festive fir in the corner of your living room harbours mould, which can aggravate the lungs.
Leading charity Asthma UK has urged people to be vigilant over the Christmas period.
Their data shows around 300 people are admitted to hospital on Christmas Day each year, suffering severe attacks, that could be linked to the festive favourite.
Mould that naturally grows on your tree can multiply in the warm temperatures of your living room.
And fake trees aren’t the safe alternative they may seem to be, gathering dust and mould in the loft, that can aggravate the lungs.
But, those with allergies as well as asthma sufferers should be alert to the dangers, Asthma UK urged. The moulds are naturally occurring on the trees, but flourish when they are inside our toasty warm homes in the winter.
But the charity also warns that both real and fake trees can also pose a threat.
Fake trees are a great alternative if the allergens that form on a real tree cause you too many breathing difficulties.
But artificial trees, and decorations, can gather dust and mould when they are kept in storage for the year which can cause a flare-up of symptoms when you put it up.
So it’s a good idea to wipe them down when you pull it out of storage and wrap them in plastic to keep the dust at bay when you put them away again.
The best supplements to take during cold winter months include vitamin D due to the lack of sunshine.
However, a new study has found that topping up on the essential vitamin could also protect against severe asthma attacks too.
Asthma attacks can be more prevalent during winter because cold air in the airways can cause them to go into spasm, according to Asthma UK.
Researchers at Queen Mary University of London discovered that people who took oral vitamin D supplements in addition to standard asthma medication could halve their risk of an asthma attack that required hospital attendance.
“On average, three people in the UK die from asthma attacks every day.
While getting vitamin D from sun exposure is the most efficient way to absorb it, people can struggle to get enough during the winter months and there is also the risk of skin cancer.
Exercise is a fanastic way to help strengthen muscles and improve heart function all at the same time. It will also give a person overall health benefits and motivation to feel good.
So how does this help you if you have a condition like asthma?
There are breathing exercises that, like aerobic exercises, can strengthen the lungs to relieve asthma symptoms or, in some cases, even prevent the recurrence of asthma attacks.
To make up for the lessened functionality of the lungs through asthma, the body uses other muscles for breathing – such as your neck, back and chest. This, however, doesn’t assist with breathing; it only adds more stress to your body, which is not good for people living with asthma.
With the following breathing exercises, asthma patients can strengthen their lungs and, thus, improve their breathing.
With a pursed lip, breathe into your nose and breathe out at least twice through your mouth.
Breathe into your nose and breathe out through you mouth at least two times. Make sure that each exhale is as long as your inhale. This helps with training your diaphragm to do most of the work while breathing, which builds up the strength to fill and empty your lungs.
If you begin to feel dizzy while practicing any of these exercises, stop immediately.Once you feel better, try again. If the dizziness continues, you should contact your doctor for help.

Coughing and experiencing a lack of breath and slow breathing be just down to age. You may never have smoked but you could still develop or be at risk for COPD and other lung diseases.
“While about 80% of COPD cases are related to having smoked, 20% are not,” says Dr. Bartolome Celli, a pulmonologist with Harvard-affiliated Brigham and Women’s Hospital.
COPD includes emphysema and severe asthma causing inflammation, destruction, or abnormal repair of airways and lung tissue, which reduces airflow and ultimately makes it harder to take in enough oxygen to supply the body.
Symptoms include a chronic cough, shortness of breath, wheezing, frequent respiratory infections, fatigue, excess phlegm, and even a blue tint to the lips or fingernails. But many of these are brushed aside.
“People may feel their symptoms are normal consequences of aging or having smoked. They don’t look for help until later in the course of the disease,” says Dr. Celli.
Early detection and prevention are key by quitting smoking; decreasing your exposure to air pollutants; getting vaccinations for influenza and pneumonia; and getting the medications necessary.
