How to Interpret the Results of a Sleep Study

I wish I had this report ten years ago when I went in for a sleep study examination. It would have really helped me understand what I was doing. And the results I received.

The National Center for Biotechnology Information has a report on interpreting the results of a sleep study. It goes step by step on the implications of a typical sleep study and each reported parameter.

If you’ve ever had a sleep study or are curious about what will be tested, I recommend you read this report. Even if you don’t have a sleep study scheduled, this is a great report on the science of sleep and all the ways we can now measure sleep in detail.

Exercise Improves Quality of Slow Wave Sleep

I’m sure this doesn’t surprise anyone, but a new study shows deep sleep is improved by exercise. The exciting part of the study, in my opinion, is from the evidence that exercise increases slow-wave stability.

A new way to measure electroencephalogram (EEG) waves was developed in 2018. The study evaluated the effects of vigorous exercise in young, healthy men on the metabolic state of sleep and its quality.

The study found an increase in density and stability of wave oscillations in early sleep phases after exercise.

These new methods for measuring the length of sleep phases and the density and stability of each sleep phase could produce exciting future research.

The Medical Futurist Discussing the Smart Sleep Alarm

Dr. Bertalan Mesko discusses the smart sleep alarm on his YouTube channel, The Medical Futurist.

Using a smart sleep alarm, you can set a timeframe for waking in the morning, for example, 5:30 am – 6:00 am. The sleep monitor will determine when you are in a light sleep phase and sound the alarm during this period, leaving you feeling refreshed.

When your morning alarm sounds while you are in a deep sleep or REM sleep phase, you may wake up feeling tired relative to waking during the light sleep phase.
