what causes cold feet

Cold feet are usually caused by poor circulation , cold temperatures, or your body’s normal blood-vessel response to stress. They can also be linked to Raynaud’s, anemia, hypothyroidism, nerve problems, diabetes, high cholesterol, smoking, or certain medicines.

Common causes

• Cold weather or low body temperature. When your body gets cold, it reduces blood flow to the hands and feet to protect core organs.

• Poor circulation. Narrowed or blocked blood vessels can make your feet feel cold, especially if it happens often.

• Raynaud’s phenomenon. Stress or cold can trigger blood-vessel spasms that make toes feel cold, numb, or change color.

• Nerve issues. If the nerves that sense temperature are affected, your feet may feel cold even when they are not actually cold.

• Other medical causes. Anemia, hypothyroidism, diabetes, autoimmune disease, and high cholesterol can all contribute.

When it matters

If cold feet happen only when it’s chilly, that is often normal. Persistent cold feet, especially with pain, color changes, numbness, weakness, or one foot colder than the other, can point to a medical issue.

Simple things that may help

• Wear warm socks or slippers.
• Move around or stretch your feet.
• Avoid smoking.
• Manage stress.
• Stay hydrated and keep active.

TL;DR: Cold feet are often harmless, but if they are frequent or come with numbness, pain, or color changes, poor circulation or another health issue is worth checking.
