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?
