Sedentary Work Offset by One Hour of Daily Exercise

One hour of physical activity daily may offset the risk of sitting at work.

About an hour of moderate-intensity activity (i.e. brisk walking) can erase the increased death rate associated with sitting at work all day. More than 1 million men and women were included in a meta-analysis which found when the least active participants (5 min. per day of moderate activity) sat all day their death rate increased by 27% compared to those sitting less than 4 hours daily. Yet, among the most active individuals (60-75 minutes of daily activity) prolonged sitting was not associated with increased death rates.

PositiveTip: If your job requires sitting all day, be sure to get at least one hour of moderate intensity activity daily.

Brawn or Brain?

Weightlifters should be discouraged from using anabolic steroids to build muscle mass.

Anabolic steroids, technically known as anabolic androgenic steroids (AAS), are commonly used by weightlifters to "bulk up." Norwegian researchers studied the brains of 82 weightlifters who used AAS for more than a year and compared them with 68 weightlifters who had never used them or other doping substances. Users had less overall gray matter and evidence of accelerated brain aging.

PositiveTip: Avoid the use of AASs and prevent the neurotoxicity of these substances which can decrease cognitive function.

10 Controllable Risk Factors Can Prevent Most Strokes

Ninety percent of strokes can be prevented.

One of the leading causes of death and disability in the world is stroke. Researchers have found there are 10 controllable risk factors that account for 90% of all strokes globally. Hypertension is the cause of 39-60% of strokes (varies among regions). The other nine causes: physical inactivity (36%), high blood lipids (fats) (27%), poor diet (23%), obesity (19%), smoking (12%), heart causes (9%), alcohol use (6%), stress (6%), and diabetes (4%).

PositiveTip: Living healthfully can reduce most of the risk factors for stroke!

Exercise First in Treating Fibromyalgia

EULAR downplays emphasis on medications for fibromyalgia.

Following a careful review of current evidence, a multidisciplinary group from 12 European countries, has unanimously endorsed the use of exercise as the first line of treatment for fibromyalgia. Exercise is very beneficial in pain management, and improves physical functioning and well-being--and is readily available, relatively low cost, and has few safety concerns. These new recommendations place lesser emphasis on medications.

PositiveChoices: Early diagnosis, good patient education, and the maintenance of physical activity increase the likelihood of good outcomes in fibromyalgia.

Night Shift Work and Driving Safety

Driving safety negatively impacted by night shift work.

When 29 anesthesiology residents were evaluated on a high-fidelity driving simulator at 8:00 AM following 6 consecutive night shifts all measured driving skills were significantly impaired, compared to when the same test was administered 10 days following transition to day shifts. Speed, lane position, throttle and steering showed significant impairment, as well as major and minor lapses in attention following the night shift period.

PositiveTip: Good quality sleep and avoiding circadian disruptions are essential to optimal driving safety.

Importance of Meal Regularity

Regular meal times are healthier!

Research in Britain involving 1768 participants examined meal regularity. Those with the most meal irregularity were 34% more likely to experience metabolic syndrome (a group of risk factors that raise the risk for heart disease) than those with the least irregularity. When this cohort was followed for 17 years those with more lunch time irregularity had a higher risk for metabolic syndrome. An early health reformer, Ellen G White wrote: "Irregularities in eating destroy the healthful tone of the digestive organs, to the detriment of health and cheerfulness."

Early Bedtime for Preschoolers

Early to bed in preschool reduces the risk of adolescent obesity.

A new study suggests that putting preschoolers to bed early may help prevent the risk for adolescent obesity. The risk for adolescent obesity was cut in half when children went to bed before 8:00 PM compared to those who stayed up past 9:00 PM. It is estimated that 25% of U.S. preschoolers go to bed after 9:00 PM, and only 25% retire before 8:00 PM.

PositiveTip: Parents, encourage your preschoolers to establish a routine of early bedtime!

Is Modest Overwieght Healthy?

Excess pounds equals higher all-cause mortality rate.

Many people believe modest overweight does not pose any health risks. A global meta-analysis of almost 4 million adults who never smoked and had no chronic conditions at baseline found all-cause death rates were the lowest when BMI was normal (20-24.9). Death rates increased significantly and linearly when BMI was above 25. BMIs below 20 also increased risk.

PositiveTip: Maintain a normal, healthy weight for the best outcome and the lowest risks.

Was Autism Just Discovered as a Side Effect of DTaP Vaccine?

"New" discoveries may not be so new!

Earlier this year an anonymous blogger reported "autism was now disclosed and acknowledged as an adverse event reported for use of DTaP vaccine." What are the relevant facts? First, the mention of autism is not "new" as it has been included as a reportable adverse event since 2005! Second, automobile accidents and drownings were also reported even though they had no casual relationship with vaccine--because FDA adverse events reporting standards dictate inclusion no matter how likely, or unlikely, it was the drug caused them.

PositiveTip: Check it out carefully before believing every report you read on the internet!

Is Iceberg Lettuce Nutritionally Worthless?

Every variety of lettuce is low in calories and rich in many important nutrients.

There are many who say the popular, crunchy iceberg lettuce is so devoid of nutrition it is not worth eating. Yet a quick look at a food composition table reveals this variety has dietary fiber, lots of water as well as vitamin K, folate, and beta-carotene. However, bibb lettuce has 6 times the beta-carotene, and romaine provides more than half the recommended daily vitamin K.

PositiveTip: Don't sneer at iceberg lettuce. Include the many other types of lettuce in your diet, also!
