What's That Rash? · Why wear a continuous glucose monitor? · 1 Sep 2026 podcast

People have different levels of energy during the day and yes, you do have a dip in the afternoon.

So if you've had a large lunch, you tend to go into a s kind of somnolent mode 'cause your parasympathetic nervous system is active to allow yourself to digest the food.
