All physical activity reduces Alzheimer's risk
An important new study shows that any physical
activity, not just exercising, is linked to a reduced risk of developing
The finding should be considered by people in middle
age, since the disease develops for years before any symptoms occur.
Protective activities included washing dishes, cooking, cleaning,
gardening and even playing cards.
Study subjects had no signs of dementia at the start
of the study, which is part of the ongoing Memory and Aging Project at
Rush University Medical Center in Chicago.
This is the first study to use an objective measure
of physical activity in addition to self-reports. Participants wore an
actigraph on their wrists to assess levels of activity. Those in the
bottom 10 percent for physical activity were almost twice as likely to
Quoted in USA Today, study leader, physician Aron
Buchman says, "The implication of this study is really astounding.
Exercise is good, without a doubt, but his study is about more than
exercise. People who might not be able to exercise can tailor activities
that are right for them."
New bronchial treatment approved for severe asthma
Individuals with severe and persistent asthma may
choose to have the bronchial thermoplasty (BT) procedure. It is
recommended for those whose asthma is not well controlled by medications
such as Advair, Symbicort or Dulera.
The treatment uses the Alair System, the first
device-based asthma treatment approved by the U.S. Food and Drug
Administration. It's used in a minimally invasive outpatient procedure
and requires three treatments, each focusing on a different area of the
lungs. They are scheduled three weeks apart. It is available in most
large hospitals, including the Cleveland Clinic, Texas Health
Presbyterian in Dallas, and Virginia Hospital Center in Arlington.
About 98 percent of patients experience significant
improvements. Patients must be at least 18 years old.
In the United States, asthma causes 10 million
hospital visits, 2 million emergency room visits, 500,000
hospitalizations, and 4,000 deaths each year.
It happens the same day, not just in the future
Physical activity generates feelings of enthusiasm.
Everyone knows that habitual exercise is good for
you, especially in the long term. But when considering physical
activity, many people wonder what's in it for them right now. Immediate
gratification would be a big plus.
You can have it, right now, today. A new study shows
that people who get at least 15 minutes of physical activity during the
day are more likely to be enthusiastic and excited about almost
everything. So if you are looking for more gusto in your life, physical
activity is one way to get it.
The study, reported in the Journal of Sport &
Exercise Psychology, found that people tend to be more excited and
enthusiastic just on days when they are more active. That should offer
encouragement to those who are intimidated by the idea of starting an
exercise program. Instead of wondering about long-term goals, they can
think about the benefits for today.
The research involved 200 people who reported their
activities, sleep quality and quantity, and their mood or mental state
throughout the day. Those who were more active also tended to sleep
better, the study found.
Other research links physical activity with levels of
norepinephrine, dopamine and serotonin in the brain, which can lead to
these positive emotions.
Though the 200-person study was small and short, only
eight days, there's little risk in getting some exercise to see how it
affects your own inner zest.
At the very least, it will be good for your heart and help to tone you
up. If you get an enthusiastic exercise high, so much the better.
Lose weight with chocolate?
Chocolate lovers finally catch a break after being
frowned upon for decades. Recent research shows that eating chocolate
five times a week or more can actually help you lose weight, improve
heart health and control cholesterol, glucose and blood pressure levels.
Its health benefits stem from antioxidants that can
help you absorb fewer calories from fat. Some diet tips:
1. Give yourself a daily allotment of chocolate.
Having boundaries is important. Decide how many of your daily calories
will be from chocolate.
2. Choose dark chocolate over milk chocolate. Dark is
lower in calories, and is more filling, so you can eat less to feel
satisfied, according to Science Daily. Dark chocolate also has
3. Include fruits, vegetables, whole grains and lean
proteins in your diet. Enjoying a variety of foods can keep your calorie
count low and your nutrient count high.
Sunscreen prevents 'liver' spots
Lentigo, also known as liver,
age or sun spots, are patches of melatonin, the substance that protects
your skin from sun exposure. They have nothing to do with the liver and
Wearing sunscreen on your hands,
arms, legs and face will help to prevent future spots from forming in
those areas say doctors at Johns Hopkins.
