Why Do Feet Swell in Cold Weather? Understanding the Causes and How to Prevent It

NJPPSG BGSMP 12.15

While it may seem counterintuitive that cold weather can cause foot swelling, there are several factors at play. Below, New Jersey Podiatric Physicians & Surgeons Group takes a closer look at why feet swell in cold weather and what you can do to keep them comfortable.

1. Reduced Circulation in Cold Temperatures

  • When exposed to cold weather, your body naturally tries to preserve heat by constricting blood vessels, thereby reducing blood flow to the extremities.
  • The reduced circulation can cause fluid to accumulate in the lower parts of your feet and ankles, leading to swelling.

2. Inactivity and Reduced Movement

  • In colder weather, people are generally less active, which can lead to poor circulation in the feet.
  • When you’re not moving around as much, fluids in your lower legs and feet can pool, causing them to swell.

3. Tight or Inappropriate Footwear

  • During winter, people often wear boots and other types of shoes designed for warmth and protection.
  • However, if these shoes are too tight, they can restrict circulation and cause swelling.

4. Changes in Sodium and Fluid Intake

  • During colder months, many people tend to consume more salty comfort foods, which can lead to water retention and result in swelling.
  • Excess salt in your diet can exacerbate fluid buildup, especially when combined with reduced circulation in the cold.

5. Underlying Health Conditions

  • If you have pre-existing conditions like heart disease, diabetes, or kidney problems, cold weather can exacerbate swelling.
  • These conditions can affect circulation, fluid balance, and the body’s ability to regulate temperature.

Swelling in the feet during cold weather is a common issue, but it’s typically manageable with the right precautions. By understanding the causes, such as reduced circulation, inactivity, and footwear choices, you can take steps to reduce swelling and keep your feet comfortable throughout the winter months.
