Finding the Ideal Glucose Level for a Good Night’s Rest

Justin Lawler is a biohacker in Dublin. He monitors various biometrics and noticed that he was waking up just before 5AM at the same time his blood sugar was crashing. An experiment quickly revealed that there is a Goldilocks zone for carbs. High blood sugar levels can negatively impact sleep quality while too low creates a risk for interrupted sleep due to hypoglycemia. Justin used a combination of the emFit prosumer sleep monitor combined with a (CGM) constant glucose monitor to find his sweet spot (~85 mg/dl) for the best night sleep.

 

He also looked at (HRV) Heart Rate Variability numbers and compared it with his glucose data at night which suggested a higher blood glucose level will lead to a faster recovery (ie. higher HRV score).

8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.

    What are the units on fig. 1? Doesn’t look like mg/dL.

  2. Justin is in Europe where they tend to use mmol/L. You can multiply by 18 to convert mmol/L to mg/dL.
