Do you ever check your phone for a quick message and twenty minutes seemingly disappear?
Studies are showing that long term use of smart phones is linked to spinal damage.
According to a study in Surgical Technology International, slouching over time can lead to the loss of the natural curve of the neck. The increased stress on the neck contributes to neck pain and degeneration. 1-2 hours of phone use won't do much, but daily use adds up to 750 hours a year. "According to the study’s authors, it is possible that a high school student may spend an extra 5,000 hours in poor posture due to cell phone and computer use... Other studies have shown that good posture even elevates serotonin and testosterone levels while reducing cortisol, a hormone associated with stress." 1
Thank gosh for Pilates and Yoga!
Both help to improve posture through strengthening, stretching and the practice of body awareness. You can more readily catch yourself starting to slouch and correct yourself.
With respect to the Pilates system, long before cell phones existed, Joe Pilates said the following himself:
“Pilates develops the body uniformly, corrects wrong postures, restores physical vitality, invigorates the mind and elevates the spirit.”
