Aerobic exercise: ‘A maintenance program for the brain’ !

By

A new study finds that aerobic exercise slows down decreasing brain size in older age, helping to maintain cognitive function.

Aerobic exercise serves as a ‘maintenance program for the brain’, researchers say.

Aerobic exercise is a type of workout that increases the heartbeat and stimulates it to pump more oxygen through the body, yet it doesn’t immediately produce shortness of breath. Some examples of aerobic exercise include running, cycling, and swimming.

Among the many health benefits that aerobics brings, some notable ones are weight loss, boosting cardiovascular health, reducing anxiety, and regulating moods.

A recent study covered by Medical News Today  emphasized how low-intensity exercise can prevent depression.

Mushrooms may help you fight off aging !

By

A new study published in the journal Food Chemistry suggests that certain mushrooms contain two antioxidants thought to improve healthspan and stave off aging.

The new research was led by Robert Beelman, professor emeritus of food science and director of the Pennsylvania State University Center for Plant and Mushroom Products for Health in State College. Michael D. Kalaras, a postdoctoral assistant in food science, is the first author of the paper.

Researchers were already aware that mushrooms are “the highest source” of an antioxidant called ergothioneine, but little was known about glutathione, another major antioxidant.

Additionally, levels of antioxidants vary across different species of mushroom, so the researchers wanted to know which species had the most of these two chemicals.

The new findings are significant in the context of the so-called free radical theory of aging. As Prof. Beelman explains, “[The theory] has been around for a long time [and it] says when we oxidize our food to produce energy there’s a number of free radicals that are produced that are side products of that action and many of these are quite toxic.”

Six surprising health risks in your home !

By

We all know that our homes can be a repository of health risks, if not managed properly. Mold, bleach, gas leaks — these are all certified hazards. But what are some of the less obvious household risks? We investigate.

Our home is our safe haven, a place infused with markers of our tastes, interests, and personalities. We share our homes with people, creatures, and things we love, and they provide comfort and joy.

Yet, our homes can sometimes also pose risks to our health. For instance, gas heaters and stoves, in the absence of proper ventilation, can release enough carbon monoxide to poison us.

Another health hazard lies in all the domestic cleaning products containing bleach. As Medical News Today reported earlier this month, using bleach-based cleaners can lead to chronic lung disease. Other common disinfectants used in the home have been linked with birth defects.

Still, these may not exactly be unexpected hazards: the toxic properties of cleaning products, for example, are no secret, and this is why we keep our stove cleaners stowed safely away, and out of the reach of children or pets.

Other household hazards, however, are nowhere near as obvious. In this article, we will look at the hidden risks in our homes, and investigate when friend turns into foe.

What is a hairline fracture?

By

Hairline or stress fractures are tiny cracks on a bone that often develop in the foot or lower leg. It is common for hairline fractures to occur as a result of sports that involve repetitive jumping or running.

Hairline fractures may also occur in the upper limb and are often related to falls or accidents.

Hairline fractures usually develop gradually as a result of overuse, as opposed to larger bone fractures or breaks that are mostly caused by acute traumas, such as a fall. While hairline fractures may heal with sufficient rest, they can be painful and last several weeks. 

Anyone who engages in regular physical activity can develop a hairline fracture, especially if the activity involves repetitive movements that put a strain on a bone or a group of bones. The most common treatment approach is rest.

Early signs and symptoms of rheumatoid arthritis !

By

Rheumatoid arthritis is a disorder where a person’s immune system attacks their joints, causing them to become inflamed. What are the early signs of this condition?

The symptoms of rheumatoid arthritis (RA) typically affect the hands, wrists, and feet. Spotting signs of RA early could lead to an early diagnosis and appropriate treatment.

Early and consistent management of arthritis can prevent joint damage and, ultimately, disability.

RA results from a problem with the immune system. When a person’s immune system is healthy, it helps to fight infection. In people with RA, the immune system mistakenly attacks the cells in the lining of their joint, resulting in inflammation of the joints, making them swollen, stiff, and painful.

People who have RA will have some periods where they experience no symptoms and other times when the symptoms flare up.

Currently, there is no cure for RA, but proper treatment and moderate exercise may help reduce flares. If RA is left untreated, the joints, cartilage, and bones in affected areas can become damaged.
