Idea to help with OCD

I get so hot so easily when I wake up in the morning I feel so hot and my legs and back feel very sticky; which is crazy because even in the winter I wear a tank top and shorts to bed and have my fans on and my mom told me they never turn the heater on. So, I don’t know if it’s due to my bed sheets because sometimes I’ll have it cover my face while I’m sleeping or have pillows on top of me. And I feel super hot and sticky even my hair feels that day when I have my pillows on me because I can’t sleep without something on me. So I’m thinking this is part of my ocd and I’ve also read if you don’t drink enough water can’t cool down and I do not nearly enough water like I should. So I’m thinking if I drink water in a water bottle and bring it with me when I go to sleep it’ll help my mind realize that I’m getting my body temperature down and i won’t be hot or feeling sticky at night because I’m drinking the water and it’s right next to me. So I can drink it before I go to bed. What are your guys thoughts on this?
