Move away from the desk for 3-minute workouts--and lower risks.

Are you glued to your computer all day long? If you are, you are probably not doing yourself or your employer a favor! Extended periods of sitting are harmful to your health. Recent research clearly indicates that all causes of mortality can be increased by too much sitting! The American Institute of Cancer Research is encouraging everyone to break up extended sitting by getting up for short periods of strength training.

Watching more than 4 hours of TV a day dramatically increases premature death.

A study of nearly 9000 Australians compared those who watched 2 hours or less of TV per day to those who watched more than 4 hours. Those watching the most had a 46% increased risk in death from all causes, and an 80% increased risk for death by cardiovascular disease. This connection stayed consistent even after adjusting for other independent risk factors.

PositiveTip: Too much sitting is bad for your health. Remember to get up and move more, and do it more often.

Couch potatoes beware - every hour of TV time may increase your risk of dying early.

Researchers in Australia followed the lifestyle habits of almost 9000 adults for more than six years. They found that each hour of daily TV viewing was connected with an 11% increased risk for death from all causes, an 18% higher risk for cardiovascular deaths, and even a 9% increase in death from cancer.

PositiveTip: The human body was designed for activity and movement. Avoid sitting for extended periods of time for optimal health.
