Poor Sleep, Weight Gain Linked In Sleep Tracking Study
POOR SLEEP LINKED TO WEIGHT GAIN IN 2-YEAR SMARTPHONE SLEEP TRACKING STUDY
(CNN) – There’s more evidence now that not getting your Z’s makes it harder to control your appetite.
In a new study; researchers used information from smartphone sleep tracking data to record sleep quality for 120,000 people for up to two years.
The results showed people with BMI’s of 30 or above; which is considered obese, had slightly shorter mean sleep durations and more variable sleep patterns.
That lack of sleep is linked to an increase in hunger and weight gain.
The results corroborated prior research, but the study has some limitations.
Fitness trackers are typically worn by younger, healthier people.
FDA approved devices would be needed to validate the data.
The study was published Monday in Jama Internal Medicine.
