Dust Off Your Desk And Get Yourself Moving



Move it..............move it


Recent studies have shown that long periods of inactivity are very unhealthy for an individual.  In fact, sitting still for long periods of time can even cancel out the effects of good exercise.  A March 2012 study of 220,000 adults by the Archives of Internal Medicine found that those who sat for eight hours or more a day had a 15 percent greater risk of dying within three years, than those that sat for less than 4 hours a day. The study found that those who sit for 11 hours or more during the day have a 40 percent greater likelihood of early death compared to those who sat for four hours or less throughout the day.
This is not good news for the billions of people with a desk job.  Studies have found that the average American sits for at least 8 hours a day and that any movement to interrupt prolonged periods of sitting does a body good. While the initial thought of exercising at work seems daunting, there are plenty of low level ways to keep active throughout the day and not even break a sweat.
1.  Ab Squeezes.  Ab squeezes are an isometric exercise that can be done while sitting.  Contract your abs and make them as hard as you can. Hold it for a second or two and then release.   Do several repetitions.
2.  Stand up.  While on the phone, stand up.  If you’re standing up you are more likely to move around the office and reduce your amount of inactivity.
3.  Sit on an exercise ball at your desk instead of a chair.  With your knees and hips at a ninety degree angle, maintaining one’s balance sitting on a big exercise ball will work your abs, pelvis, back, and hips.  There are chairs made with an exercise ball to sit on instead of a traditional cushion, as well!
4.  Squeeze stress balls. Stress on top of inactivity is very unhealthy for a person.  Grab a stress ball or two and squeeze and release them. Hold them in your outstretched arms and squeeze them while you move your arms in a circle. The act of squeezing will leave you less tense and circling your arms exercises your shoulder and pectoral muscles.
5.  Take the stairs.  Instead of taking the elevator, take the stairs to your office.  Walking up the stairs is likely one of the best calorie burners you can do while at work. Take the stairs whenever you can.  Walk up the stairs to go to the bathroom on a different level of your office building, etc.
6. Crunches. Traditionally crunches are done on the floor, but you can also do them from a seated position in a chair.   Sit straight with your knees bent and feet on the floor.  Put your hands on the sides of your head and curl your body downward.  Squeeze your abs, rise up and repeat.
7.  Pump your fists in the air rapidly, like a boxer for thirty seconds.  Hold something in your hands, like a paperweight or bottle of water while you do this for extra effect.  Then tap your feet on the floor rapidly, like a football ball drill, for 30 seconds.  Repeat these activities 3 to 5 times.
8.  Stand beside your desk, look at the clock, and do jumping jacks for one or two minutes.  Do this every hour you’re at work.
9.  Sit in your chair with your legs straight out and unsupported. Hold for as long as you can, then slowly put them down, keeping the tension in your abdomen.  Repeat.
10.  Sit in your chair with your legs crossed and your feet on the seat. Place your hands on the armrests, suck in your gut and raise yourself a few inches above the seat, using your belly, muscles and hands. Hold for 10 to 20 seconds. Rest for 30 seconds. Repeat five times.
Get creative with your office exercises.  Get your co-workers involved.  Be mindful of your inactivity throughout the day and be proactive in keeping your body moving. What are some exercises you do while at your desk?

Antioxidant Defense May Play Important Role in Asthma Prevention - health blog

Antioxidant Defense May Play Important Role in Asthma Prevention




An impaired ability to handle oxidative stress that arises from exposure to secondhand smoke and other environmental triggers may contribute to the development of asthma, according to results obtained from the Shanghai Women’s Health Asthma and Allergy Study. The results of the study suggest regulating the body’s antioxidant defense system may play an important role in asthma prevention.


“We found that the host antioxidant defense system is compromised among those destined to develop asthma, and therefore these individuals may be less able to handle environmental exposures that may cause asthma,” said study author Emma Larkin.”Oxidative stress, which is a relative increase of oxidants over antioxidants, is known to be important in many diseases, including asthma,” said Dr. Larkin. “It’s a battle between charged oxygen species that produce damage and our body’s ability to fight them off.”
Dr. Larkin said humans have two ways of building the antioxidant defense: by improving dietary intake of antioxidants (for example, Vitamins A, C and E), called the “non-enzymatic approach;” and by strengthening the host defense system to more effectively use antioxidant enzyme activity to remove oxidants from the system, or the “enzymatic approach.”
“In our study, we took a multi-step approach to understanding the development of asthma, by looking at the enzymatic and the non-enzymatic ways that the body manages oxidative stress in the development of adult-onset asthma,” Dr. Larkin said.”Specifically, we focused on the enzymatic defense system that precedes the onset of asthma symptoms and diagnosis.”
The researchers collected data from 65,732 women with no history of asthma who completed standardized questionnaires about asthma diagnoses and symptoms on two occasions following enrollment. From this group, the researchers selected 150 women with confirmed new development of asthma and 294 healthy controls. Levels of antioxidants and other enzymes associated with oxidative stress were measured from blood and urine samples prior to asthma development. Questionnaire data indicated 96 percent of the women were never-smokers and 44 percent were exposed to secondhand smoke through husbands or workplace exposure.
“Exposure to secondhand smoke increases the risk of asthma, and we believe that our ability to combat the detrimental effects of environmental exposures such as secondhand smoke through antioxidant enzyme defense is very important,” Dr. Larkin said.
The researchers found that increased host antioxidant defense enzyme activity measured prior to disease onset was associated with a reduction in risk of asthma. Specifically, high levels of an enzyme that prevents the formation of platelet-aggregating factor (PAF), which is linked with asthma, were associated with a decreased risk of asthma.
Dr. Larkin said the study is the first incidence study to assess the role of antioxidant defense on asthma risk, and may help researchers develop treatments to help asthma prevention in patients who are at risk for the disease.
“Because this study helps us understand what is occurring in the body prior to the development of symptomatic asthma, the results may point us to nutrients or classes of drugs that could be studied for asthma prevention in those who are high-risk,” she said.
“There are a lot of data on the dietary intake of antioxidants and levels of antioxidants in the blood – the non-enzymatic defenses,” she added. “By focusing on the enzymatic defenses, this study helps give us a clearer picture of the complete asthma development process.
