Why do some people get more sensitive to cold

Some people might find themselves shivering more easily than others, even when the temperature isn’t particularly low. This increased sensitivity to cold can be due to several factors.

Firstly, **circulation issues** play a significant role. When blood vessels constrict or vasoconstrict, it reduces blood flow to the extremities like hands and feet. This is a natural response to conserve heat in the body’s core, but it can leave the extremities feeling colder than usual[4]. Conditions like poor circulation or certain health issues can exacerbate this effect.

Another factor is **stress**. Stress can cause blood vessels to constrict, leading to a sensation of coldness, especially in the hands and feet[2]. This is because the body’s stress response prioritizes blood flow to vital organs over peripheral areas.

**Hypertension** can also contribute to cold sensitivity. High blood pressure can lead to hypertensive vasoconstriction, which reduces blood flow to extremities, making them feel colder[2].

Additionally, **thyroid issues** can affect how sensitive someone is to cold. An underactive thyroid, or hypothyroidism, can lead to a lower body temperature, making people feel colder more easily[3].

Lastly, **lifestyle factors** such as intense exercise or exposure to cold environments can temporarily increase sensitivity to cold. This is because the body takes time to adjust to new conditions, and sudden changes can leave someone feeling colder than usual[1].

Overall, sensitivity to cold is influenced by a combination of physiological, environmental, and health-related factors. Understanding these causes can help individuals take steps to manage their sensitivity and stay warm.
