Why do I get cold at certain time each day?

Recently I noticed I get cold regularly in the evening/at night.  I'll be fine during the day, but around the evening when it's not even very dark outside yet, I start to feel chilly and shiver.  It is very regular.  

Just to be clear it is not too extreme.  Nothing a jacket and blankets won't help.

I tried googling it, but all I found was how you get colder when you sleep.  But when I start getting chilly it is not that late yet and I'm not sleeping.

Why is this?  What does it mean?

I use to get cold every time after I ate, but it finally stopped. I really have no idea as to why it happened, possibly due to digestion issues.

Okay!  Now you are talking my language here!  This is really fascinating to me.  Our internal body temperature is attached to circadian rhythm! https://www.sciencedaily.com/releases/2010/10/101014144314.htm It has something to do with light entering your eye as the evening goes on and preparing you for the 'next' thing which is sleep.  The change in temperature is part of what sends a signal to your brain that it is getting to be time to sleep.  Scientists call it the 'temperature clock'!
