Forehead always feeling warm no fever.

So basically my forehead always felt warm when compared to my back of the hand temperature.. however no fever recorded or any discomfort of any kind no pain or anything and many of the times when some one else compared using hands to guess whether forehead was warm or not ... around 70% or times it was okay.i am obese so could it be that my hands are much cooler than my face(especially my biceps feel v.cold during winter due to poor circulation) or something...can someone just a good way to regulate body temperature..all my blood report are normal and so is my Infra temperature of forehead is always between 97.8.oral temperature around 98.6 .wrist temperature (infra ):97.1-97.3..my iron is low in blood test...also my WBC has always been on the higher side since as long as I can remember..I had dengue last semester. I consulted before this and a doctor said that my WBC and platelet are more as I drink too little water (1-1.5L (max)In a day. Vitamin d low 17.82 ng/ml Iron low 57.5ug/dl
