Consumer sleep monitors not perfect

Dear Dr. Roach: In one of your columns, someone asked if it was helpful to just rest during the night, and how did that compare to sleeping if one is unable to sleep.

You said just resting was not that helpful, that one really needed sleep. I wanted to ask about “restless” minutes as recorded by a fitness watch.

Restless minutes are separated from awake minutes, so I am referring only to the times when I’m moving but still asleep.

Why are these subtracted from actual sleep time? I usually have no trouble sleeping and wake up on my own within six hours, but I’m always surprised because my fitness watch subtracts these restless minutes from the time slept. They often add up to around 30-45 minutes.

Answer: “Restless sleep” isn’t a term used by sleep experts, and I am not sure what your sleep device is registering. It could be that you are indeed asleep and moving around.

Consumer sleep monitors are not perfect, and the device could be misreading what is happening. If you feel like you sleep well, and you aren’t sleepy during the day, odds are that you are sleeping just fine.

Dear Dr. Roach: I’m a healthy 32-year-old woman. I went into the emergency room last week with a 103.1 fever caused by a urinary tract infection. The doctor took a CT scan of my abdomen and found fecaliths. I have some constipation, but nothing to the extreme. I was drinking prune juice to hopefully make it pass. I don’t know what else to do.

Answer: “Fecalith” comes from Latin and Greek roots meaning hardened or stonelike feces. These occur in people with slower-thannormal stool passage time. The cause could be intestinal disease, but it’s also seen in people who don’t get a lot of fiber or who are chronically dehydrated.

Since these were found incidentally, and you are reporting no symptoms from them, it’s not necessarily something you need to worry about.

However, you can help keep your intestines healthy by exercising, getting plenty of fiber (from vegetables and whole grains or from supplements), and drinking plenty of water.
