Study: Walk breaks at work help blood pressure

Doctors are recommending activity breaks every 30 minutes to fight the negative health effects of sitting all day at work.

A new study finds that a short walk every half hour may prevent harm from all that sitting.

In the new study, volunteers who got up and walked for five minutes every half hour had lower blood sugar and blood pressure than those who continued to sit.

The study was published in Medicine and Science in Sports and Exercise.
