Obese people:
The obese people are generally more prone to attain skin rashes because heat tolerance subsequently decreases in the people who have higher amounts of fat in their body tissues. Moreover, the excessive skin when overlaps with skin fold areas, then there are more chances of friction on the surface of the skin. If a fat person gets heat rashes in one of the areas where the skin folds are present like the armpits, the area under the breasts, the back area of knee joints, and the elbow joint area, then there is difficulty in healing of that particular skin area.
