"I can't sleep..." Sleep problems during self-isolation
Recently, with the spread of COVID-19, measures such as refraining from going out and closing schools have been taken.
These measures have resulted in people no longer commuting to work or school, which has led to disruptions in lifestyles and sleep rhythms, and an increasing number of people are complaining of a decline in the quality of their sleep. Globally, the hashtag "#cantsleep" has become a trending topic on social media, and it appears that an increasing number of people are suffering from "corona fatigue" and "corona depression."

Sleep experts point out the impact of spending more time at home on sleep

While practicing medicine as a doctor, he places emphasis on prevention and strives to provide guidance to improve the quality of sleep, based on the concept of "living a healthy life through good sleep." He disseminates information about sleep through various media, including the Internet, television, and magazines.


Based on the professor's comments, it is likely that many people are suffering from insomnia these days, as they tend to stay at home, have fewer opportunities to exercise, and spend more time watching electronic media.

You might need to improve your bedding! Sleep expert Dr. Tsubota shares his sleep checklist

■Rethink your current bedding to improve your sleep <br>According to Dr. Tsubota, if your mattress is too hard, you will feel pain where your body touches it and will not be able to sleep well. On the other hand, if your mattress is too soft, your body will get stuck in the mattress and you will not be able to turn over, which will result in poor quality sleep and pain and stiffness in your body. Also, as the mattress gets older and the material deteriorates, the area around your lower back will sink in. This can cause lower back pain and make it difficult to turn over, resulting in poor quality sleep. Furthermore, if your mattress is not properly maintained, mold and dust mites will grow inside the mattress, which can lead to asthma and allergies, so rethinking the mattress you are currently using is an effective way to ensure a good night's sleep.


Introducing products to improve your sleep
A super convenient item that lets you easily upgrade your bedding
■ "Mattress topper"
A mattress topper is a support bedding piece used in conjunction with a mattress. It's basically used by placing it on top of your mattress when it starts to wear out or become uncomfortable. Even if you're hesitant to discard your current mattress or buy a new one because it's too much hassle to carry in a new one, this one piece can help you upgrade your sleep. It's also a highly functional and convenient item, as it can be used in place of a futon and can be stored compactly.
