Why are my feet cold and sweaty?

Cold feet are your body’s normal response to temperatures dropping, especially in cooler climates or during winter. As a natural way of regulating temperature, your body keeps blood flowing to your core to keep vital organs warm by constricting blood vessels in your hands and feet, making them feel colder.

Ever wonder why your feet are cold but sweating, too? Sweat can make your feet feel colder even when it’s not cold outside. When sweat evaporates quickly, it cools the feet and makes them feel cold. People with excessively sweaty feet, or plantar hyperhidrosis, may often have cold feet, too.

If you happen to sweat too much, then having cold, sweaty feet might be a problem affecting your daily life, leading to discomfort or embarrassment. As you struggle to keep your feet dry, sweaty feet can also cause bacteria to grow, leading to smelly shoes or athlete’s foot.

Causes of Cold, Sweaty Feet

Cold feet are usually temporary. However, some people have chronically cold feet that may be associated with medical conditions or underlying diseases. It’s important to talk to your healthcare provider if your feet are constantly cold to the point of discomfort or even pain.

Some of the most common causes of cold and sweaty feet include:

  • Anxiety or stress disorders that make you sweat
  • Wearing shoes that are too cramped or not breathable
  • Side effects to certain medications
  • Poor blood circulation
  • Autoimmune conditions and deficiencies like anemia
  • Hormonal imbalances like menopause
  • An overactive thyroid that can mess with circulation, deregulate metabolism, and throw off hormones
  • Neuropathy, which can cause excess sweating and body temperature changes in diabetics
  • Peripheral Arterial Disease (PAD), which causes reduced blood flow to the arms and legs
  • Raynaud’s Syndrome, which happens when blood vessels in the hands and feet overreact to cold temperatures

Other Symptoms Related to Cold Feet

Depending on the cause of your cold feet, you might experience other symptoms which may or may not be related to a medical condition. Discomfort like mild pain, tingling, or numbness as well as difficulty warming your feet could indicate an underlying problem and should be addressed by a medical doctor.

Feeling anxious can easily trigger the body to start sweating, especially in response to a fear or stress inducing event. When you feel stressed, your heart rate and body temperature increase, causing you to feel hot. This releases stress hormones that activate your sweat glands, increasing the rate of perspiration in your armpits, hands, feet, and other areas of the body to keep you cool.

People with anxiety disorders might experience problems with sweating more often, which could lead to more feelings of worry or embarrassment over frequent sweating. The sweat cools and evaporates, making your feet feel cold and clammy, and the cycle continues the more you sweat. Thankfully, moisture wicking sock inserts like FLAT SOCKS can help you manage your cold, sweaty feet.

Foot hygiene is essential in keeping feet that sweat too much healthy. Wash and dry your feet daily and completely. You should also allow your feet to breathe when you’re able to, such as not wearing shoes in the house. FLAT SOCKS shoe inserts are machine washable, too, so you can keep them clean like normal socks.

Foot deodorants like creams and sprays can help prevent foot sweat at night by temporarily blocking your sweat glands, though you must wash it off first thing in the morning. Healthcare providers may prescribe antidepressants or nerve blocks if they believe your clammy feet are related to anxiety or a nerve condition.
