A good night’s sleep

| 6 Comments

We all know that sleep is important to re-charge our bodies, but it’s also a key factor in maintaining a healthy weight, energy and mood levels. And recent research reinforces this, with even more reasons to ensure a good night’s sleep. Monitoring your sleep & activity patterns is the first step to making positive changes.

One recent study showed our on the go lifestyles and trend of lower average sleeping hours may also be tied to the growing incidence of Type 2 diabetes. This study measured insulin sensitivity after a “good” night’s sleep (8 hours) and again after a “poor” night’s sleep (4 hours).  Changes were noticed after just one night of poor sleep. Dr. Esther Donga, the lead author of the study speculated “The co-occurring rises in shortened sleep and diabetes prevalence may not be a coincidence. Our findings show a short night of sleep has more profound effects on metabolic regulation than previously appreciated.

Another recent study found an increased risk of childhood obesity for children who don’t get adequate sleep.  The relation was particularly strong for boys and young children. The study tracked over 700 young people monitoring how long they slept, self-reported sleep problems, and the foods & beverages they consumed. The shorter sleep durations were related to higher body mass index and also to the percentage of body fat.

Both good reasons to make sure you get your zzz’s.

    How does the sleep tracker work? Does every time I roll over count as a non-sleep period? I seem to have a LOT of times when I wake up during the night, for example, anywhere between 11 and 16 times.

    I also would wake up a lot during the night. I found, for me , that I would roll to my stomach and that caused pains. So I bought a body pillow to help with this.

    What is the technology used to capture sleep quantity and quality? Is there any data to support the accuracy and reliability of the Fitbit regarding sleep data; e.g. compared to polysomnogram lab test?

    Since I had gotten my fitbit, I had been tracking my sleep. I noticed I woke up an unusual amount of times during the night. Averaging 25 sometimes as high as 57. After a few months, I talked to my physician about it and showed her my averages. It was enough for her to order a sleep study. I have found out that I have sleep apnea and am the proud owner of a cpap machine. I would not have known unless my fitbit told me. I thought I was getting decent sleep at night. Thank you fitbit !!!

    How does the sleep tracker work? I’m in bed 8 hours but only get logged for about 6 hours 15 minutes. My 41 wakeups seem to be in line for apnea treatment-how accurate is that for a sleep apnea diagnosis?
