Cold Feet
Cold feet during the winter season are primarily due to our body's natural thermoregulation process. When exposed to cold temperatures, our body activates a survival mechanism called vasoconstriction. This process narrows the blood vessels in your extremities, like your hands and feet, to minimize heat loss and redirect blood flow to vital organs, such as the heart, brain, and lungs, which are essential for survival. 
This reduced blood flow to the feet decreases their temperature, making them feel colder than the rest of your body. Additionally, since feet have a larger surface area relative to their volume and are often in direct contact with cold surfaces, they lose heat faster. Wearing inadequate footwear or socks in cold weather can exacerbate this effect, leaving your feet even more vulnerable to the chill.
