In summer, even a moderately fast-moving fan keeps us cool. If it is an AC, the comfort is another level altogether. But once the cold season sets in, the chill almost bites. One can imagine how it must feel when there is snowfall. Yet, at the same temperature, some neighbour might be enjoying a stroll with hardly a hint of discomfort on account of the low temperature. The intensity of the sensation of warmth or cold is thus different for each person.
However, doctors say that for some individuals, this excessive cold might also show that an underlying condition exists in their body. It could reveal how the body regulates its own temperature. But what else can make one feel cold almost all the time?
1) Iron deficiency and impairment of blood production
Iron is essential for making red blood cells, which carry oxygen throughout the body. If iron levels are too low, the whole system suffers. The human body cannot produce enough heat on its own, which results in cold hands and feet and a continuous feeling of chilliness.

2) Underactive thyroid
The thyroid gland is butterfly-shaped and is found at the base of the neck. It produces thyroid hormones, which play a vital role in controlling metabolism and in maintaining the body's temperature. If these hormones are not secreted in adequate amounts, hypothyroidism results, and the "heat engine" of the body slows down or stops working. People with hypothyroidism often feel extremely cold.
3) Low body fat
Body fat is a natural insulator that helps retain body heat and distribute warmth. Individuals with extremely low body fat do not have this layer of protection. Individuals with a below-normal body mass index (BMI) are more sensitive to cold.
