There's always been a friendly discussion between those who wear socks in bed and those who'd rather sleep barefoot. However, there are scientific arguments about the reasons why sleeping with socks on can actually have a positive impact on your health.
Many people argue over the reasons why you should or shouldn't wear socks in bed while you sleep. However, their arguments are usually related to what's more comfortable or what looks better, not to what the healthiest option for your body is.
First of all, it's necessary to go over the whole process that takes place from the moment you put on your socks to the time you actually fall asleep. In this process, many parts of your body play a role and there are certain steps that happen that you may not even be aware of!
Let's start with the direct consequences of putting on socks. These cause your feet to warm up, which translates inside your body to an increase in the blood circulation directed to your feet. This is actually what happens when you warm any part of your body.
Once the blood circulation is boosted, your blood vessels find themselves with a greater flow to contain. This is the reason why they widen or, as it's called, they vasodilate. The consequence is a quicker heat loss in your body, made easier by the bigger surface from the blood vessels.
When the blood vessels in your feet widen, the heat is redistributed all over your body. The resulting effect is a fast drop in your core body temperature, a very important step in this chain of events.
The reason why a colder body is key to the effect of socks on sleep is that lower core body temperature is one step that your body takes to prepare itself to sleep. In other words, your brain associates this cold with your bedtime, which is why warming up your feet can shorten the time it takes for you to fall asleep.
To conclude, it can also be mentioned that not only feet can be warmed up to cause vasodilation, lower the body temperature, and induce sleep. The same effect can be achieved if you wear gloves to heat cold hands, as the blood vessels there will have the same effects.
Hopefully, this information was useful for you! Sleep is very important to maintain a healthy body, which is why it’s key to understand how it works and how you can improve its quality and duration. Even the smallest changes like wearing a pair of socks can make a big difference!
