A foot massager with heat can noticeably warm up cold feet. The heat widens the blood vessels in the skin, the massage loosens the muscles, and both feel pleasant after a cold day. It does not tackle the cause if your feet are permanently cold. If you also notice numbness, pain or changes to your skin, have it checked by a doctor. If you have diabetes or nerve damage, use heat only with caution.
Why feet get cold so quickly
In the cold, the body protects its core first, meaning the heart, lungs and abdominal organs. To do this, it narrows the blood vessels in the hands and feet. Less warm blood flows into the toes, and the skin cools down. This is a normal reaction and not a sign of illness.
Everyday reasons add to it: long hours sitting at a desk, thin socks, wet shoes or a cold floor. If you move little, your calves pump less blood back, and your feet stay cold for longer.
What a foot massager with heat does
Heat
The heating function warms the soles of your feet from below. Warm skin lets the fine blood vessels widen again, circulation in the feet improves and they feel warmer. This works while the device is running and for a while afterwards.
Massage
Rollers, kneading or air pressure move the tissue on the sole, the heel and often the calf too. This loosens tense muscles and can feel very soothing after a long day standing or sitting. How the different devices work is explained in How does a foot massager work?.
What it cannot do
A foot massager does not treat a circulatory disorder. If blood vessels are narrowed or nerves are damaged, the device only warms the surface. What a device can and cannot do for circulation is covered in Is a foot massager good for circulation?.
When cold feet should be checked by a doctor
Occasionally cold feet in winter are normal. Have it checked if any of these apply:
- Your feet are constantly cold, even in warm rooms.
- One foot is noticeably colder than the other.
- Your toes turn white or blue and hurt as they warm up.
- You feel tingling, numbness or pain when walking.
- Wounds on your feet heal poorly.
Signs like these can point to circulatory disorders, nerve damage or an underactive thyroid. In that case, the question belongs with a doctor first.
Take care with diabetes and nerve damage
If diabetes or polyneuropathy has reduced your sensation, you often do not notice in time when the heat is too high. This can lead to burns that heal poorly. In this case, only use the heat after consulting your doctor and on a low setting, and check your skin afterwards. More on this in Are foot massagers suitable for diabetics? and When should you not use a foot massager?.
How to use the device on cold days
- Dry your feet first and take off wet socks.
- Start with low heat and a gentle massage.
- A programme of 15 to 20 minutes is enough; longer usually brings nothing extra.
- Afterwards, put on warm socks so the warmth stays.
- Get up now and then and walk a few steps. That helps your circulation just as much.
How long and how often a session makes sense is described in How long can you use a foot massager?.
What to look for when buying
For cold feet, what matters most is a heating function that can be switched on separately from the massage and adjusted in levels. An automatic shut-off is important in case you fall asleep. Calf air cushions are a plus if your legs also feel heavy. You will find devices with these functions in the overview of foot massagers.
Frequently asked questions
Does a foot massager warm better than a hot-water bottle?
The warmth is similar. On top of that comes the massage, which loosens tense muscles.
Can I use the device every day?
Yes, if you are healthy and stick to the recommended duration.
Does it help with cold hands too?
No, it is not built for that. If your hands and feet are both cold, it is more worthwhile to look at exercise, clothing and, if necessary, medical advice.
When should I see a doctor?
If your feet are constantly cold, change colour, go numb or wounds heal poorly.
