Many people notice that they reach for an extra sweater long before anyone else in the room.
It can feel like a harmless quirk, yet for a surprising number of people, that persistent chill is the body’s way of signalling that something deeper is influencing temperature control.
When the body struggles to stay warm
The ability to hold on to warmth depends on how efficiently the body moves oxygen, produces energy and keeps circulation flowing.
Researchers in metabolic and vascular medicine note that even mild disruptions in these systems can make cold sensitivity far more noticeable.

Low iron levels, reduced oxygen transport or sluggish circulation can all limit the body’s natural heat production, leading to cold hands, cold feet or an overall sense of chill that lingers.
How body composition and nutrients play a role
Insulation matters, and people with low body fat often lose heat more quickly. Muscle mass can also influence how warm someone feels, since active muscles generate heat.
At the same time, blood vessel function and blood pressure affect how warmth spreads through the body, making circulation a key factor in temperature regulation.
Common contributors include:

- Low nutrient stores, especially iron and vitamin B12
- Hormonal changes or reduced thyroid activity
- Poor circulation
- Low body weight or reduced muscle mass
When cold sensitivity signals imbalance
Feeling cold more often than others may seem trivial, but it can point to underlying changes in hormones, blood volume, metabolism or nutrient status.
Health researchers highlight that diet adjustments, medical evaluation or targeted treatment often improve cold tolerance once the root cause is identified. When the body regains the balance it needs, warmth typically returns just as quickly.
