Sleeping with a smartwatch

But the question is: Should you wear your Smartwatch to bed? Is it bad to sleep with a watch?

Smartwatches come in different sizes, and if you have the Smartwatch that you are comfortable wearing with, then there’s scientifically no reason which bars someone from wearing the Smartwatch to bed.

Here is an article on my website that you must read, its about the Best 10 Sports Apps For Smartwatch To Get Live Games Score In 2023.

If you are comfortable with it, then you can surely wear your Smartwatch to bed. Let’s have a closer look at this topic.

Is It Bad To Sleep With A Watch On?

Back in the days, smartwatches used to be very bulky, but now they are better and lightweight than ever. There are smartwatches out there which you can wear all day and night, and they won’t cause any strain to your wrist.

So, at the end of the day, it will all depend on your personal preference. In my case, I don’t like to wear my Smartwatch to bed because it doesn’t make me feel comfortable. However, I wear it from time to time to check my sleep analysis, which helps me understand the sleep quality I’m getting.

So, if you also don’t like to wear Smartwatch to bed, you can keep it near your bed, and that’s perfectly fine.

However, if you want a detailed analysis of your Sleep like the duration of your Sleep, the quality of your Sleep, and other details, then you should wear the Smartwatch to bed.

Also, you can get a lightweight & thin Smartwatch, which won’t cause any strain. You can check my guide on Thinnest Smartwatch, where I have shared the 11 Best Thinnest Smartwatches.

Is My Smartwatch Negatively Affecting My Health?

Fitbit’s Sleep Tracking

Although there is no scientific study that claims that smartwatches negatively affect our health, there are some opinions on this topic.

As most smartwatches emit radiation, many people believe that person should not wear the Smartwatch to bed. As we absorb a lot of radiation throughout the day, we must give a break to our body and get a good sleep.

It’s also true that most smartwatches come with very low SAR Levels, which are not dangerous to human health, and these SAR Levels are within the FCC’s defined Limits. Read here my SAR levels comparison between Fitbit, Apple Watch, and Samsung.

Some people also link smartwatches with Headaches, but there is no scientific study that proves this claim. I have covered this topic in detail, and you can check my guide, where I have listed some scientific research.

Pro Tip: if you don’t want your Smartwatch to emit Radiations at night, you can turn off your Bluetooth and Wifi, which will reduce the Radiations to a great extent.

In conclusion, there is no substantial evidence available supporting this claim that Smartwatches negatively affects our health.

However, if you feel that wearing Smartwatch for extended periods causes headaches, you can stop wearing your Smartwatch to bed. Also, don’t forget to check my guide on Best Fitness Trackers without Radiation, where I have shared the best trackers that come with no or lowest radiations.

Frequently Asked Questions [ FAQs ]

How Tight Should A Watch Be?

If you wear your Smartwatch to bed, you should ensure that your Smartwatch should not be very tight. Normally, I like to have the space of 1 finger between my wrist and the strap, which is the right fit for a Smartwatch.

Which Smartwatch Band Is Ideal For Wearing At Night?

I personally use the Nylon band for my Smartwatch because it’s comfortable and breathable material. I would not recommend wearing silicon or metal strap to bed because these two materials are not ideal, and metal strap can potentially hurt you.

So, if you want to wear your Smartwatch to bed, make sure that you have nylon or any soft material strap.
