The Fitbit is the Thermos of wearable fitness devices. Other companies have their versions with different feature sets and styling. As the market saturates, what will the manufacturers do to retain their market share and profits? They’ll undoubtedly add features until the devices will be doing instantaneous blood glucose screening and innoculation against tropical diseases.
Sanjay Gupta has an opinion on all that, feeling that all data is not created equal. In this article naming three data points to use and two to ignore, I found it interesting that he seemed to agree with the Bible on the most important piece of information your Fitbit can provide: rest, or rather sleep.
If you’re going to monitor only one thing, this is it: Without adequate rest, your whole body suffers. The best way to measure the quality and quantity of your sleep is with brain wave technology, but that’s not yet practical outside a laboratory. Some of today’s trackers offer only approximate results based on how restless you are during the night, so you’re not going to get perfect data.
Gupta is correct, of course, but his wisdom is nothing new. In Exodus 20:8-10 we are instructed to rest.
Remember the Sabbath day, to keep it holy. Six days you shall labor, and do all your work, but the seventh day is a Sabbath to the LORD your God. On it you shall not do any work, you, or your son, or your daughter, your male servant, or your female servant, or your livestock, or the sojourner who is within your gates
Granted, the Fitbit cannot tell you if you are keeping your Sabbath rest. Sleep and rest are not synonymous, but without rest, the human body will not function properly. It’s just another one of those ways that humans have been hardwired to demonstrate that there is a God and we’re not it.
