Is it OK to wear socks when sleeping? Advantages and Disadvantages of Socks

When it gets cold, don't you want to put on a pair of socks when climbing into bed?

I have poor blood circulation which leads to very cold feet. 

My husband always complains when my feet - icicles, he calls them - accidentally touch him under the covers.

I sometimes wear my socks to sleep to help my feet stay warm.

But, what are the consequences of doing this?

Today, I will introduce the benefits and disadvantages of wearing socks when sleeping. 


Is it Good or Bad to Wear Socks When Sleeping?


There are varying views about whether or not socks should be worn during bedtime.

Some say, that socks can cut off circulation or slows down blood flow.

On the other hand, some may think that “if your feet are too cold, it’s hard to fall asleep. So in this case, you should wear socks.

In the next section, we will explain the disadvantages and advantages of wearing socks when sleeping.

Disadvantages of Sleeping with Socks


If you sleep with socks on, you might want to know about these disadvantages.

Your feet can get stuffy and uncomfortable, which can interfere with your sleep.

Even if your feet are cold before you enter your bed, it can get hot if you keep your socks on in the warm environment inside the blanket. 

Then, you will sweat and start to feel stuffy. 

You may feel uncomfortable with the stuffiness.

Furthermore, if you wear socks while sleeping, your toes will not be able to move freely. 

Then, the capillaries are tightened and blood circulation is impaired. 

Stagnation of blood circulation may make it easier to get cold and cause swelling.

The heat builds up in the toes, so the core body temperature does not drop and the quality of sleep deteriorates.

Recent studies on sleep show that before going to sleep, the human body has increased blood flow in the skin and increased heat dissipation. As a result, the internal body temperature of the body decreases and sleep is induced. 

In particular, it is the backs of the hands and feet that cause an increase in skin temperature prior to sleep. 

In other words, when the blood flow in the limbs increases and the skin temperature rises, the body becomes more likely to fall asleep.

Many of you may know empirically that "it's hard to fall asleep when your feet are cold", but this is the correct view from the viewpoint of sleep mechanism. 

Therefore, it is important to keep your feet cool when you fall asleep.

However, if you sleep with your socks on, heat may be trapped inside the socks and the heat release from your feet may be hindered. 

If this happens, your core body temperature will not drop enough and you will not get a good night's sleep.

Advantages of Sleeping with Socks

The advantage of sleeping with socks is that warming your feet makes it easier to fall asleep.

As explained in the previous section, if you do not raise the skin temperature of the limbs and release heat, not only the limbs but also the core body temperature of the whole body will not decrease, so it will be difficult to fall asleep. 

This is the reason why it is difficult to fall asleep when the room temperature is low, the futon is cold, and the limbs are cold, or when the limbs are cold due to chronic coldness.

From this, it can be considered that it is important to warm the limbs and raise the temperature in order to make it easier to fall asleep. 

Therefore, it is recommended to take a warm bath before going to bed, take a foot bath if you cannot take a bath, or massage your feet. 

However, warming your feet with socks is only effective for smooth sleep onset. 

As mentioned in the section on disadvantages, if you sleep with socks on, the heat will be trapped and the heat release from your feet will be hindered, and you may not be able to get a good night's sleep.

For Those Who are Too Cold to Sleep

As mentioned above, wearing socks during sleep increases the blood flow and surface temperature of your feet, which has the advantage of making it easier to fall asleep. 

However, on the other hand, if your feet get too warm, you will get stuffy, and if you release too much heat, your body will get cold.

If your feet get cold and you can't sleep, we recommend the leg warmer type, which does not cover your toes.

If you want to wear socks even when you fall asleep because your fingertips get cold, choose one that is easy to take off.


It's getting colder day by day, and some people may be worried about the coldness of their feet when they go to bed. 

Before going to bed, take measures such as soaking in the bath to warm your feet, massaging, and wearing socks to create a state where you can fall asleep smoothly. 

It is also important to take off your socks as soon as you feel "hot" after entering the futon. 

Keeping your feet cool and not hot is the best way to get a good night's sleep.
