Long hot showers feel so good, but make me tired?

Hi guys,
So here is my problem. My body temperature seems to be colder than normal with my extremities being the coldest and most uncomfortable. I've had this problem for several years now.

I crave hot showers. And I am usually in the shower for 15 minutes. For about 2-3 hours afterward I just feel depleted with no energy to do anything.

I have Adrenal Fatigue which is milder now than a year back when it was more severe. I also have Candida and Parasites. I have a congested Liver. Also Brain Fog, skin problems and anxiety.

Usually I love the summer months and hate winter (in NJ). I loved the summer even when I was in Arizona. Of course absolute extreme heat was uncomfortable but I liked 90 degree weather. I had AF then too.

SO WHAT GIVES? And what can I do about it? Could Candida and parasites be contributing? Will exercise help to heat up the body?

Your help is appreciated much!
