Growing Interest in Modern 'Sleep Issues' Reflected in First New Medical Department Name in 18 Years

On June 1, 2026, 'Sleep Disorders' was added as a new medical department name, the first in 18 years. This historic revision reflects the surge in modern individuals suffering from insomnia and excessive daytime sleepiness, indicating that 'declining sleep quality' has become a concern that society as a whole must address.

While the number of people requiring specialized medical support is increasing, reviewing one's immediate sleep environment is also an important approach to alleviate daily 'sleeplessness' and 'morning fatigue.'

Summer: The Toughest Season of the Year. Update Techniques to Graduate from 'Tired Even After Sleeping'

Summer, with its 'tropical nights' where temperatures and humidity remain high after the rainy season ends, is the season with the harshest sleep environment. 'Sleep debt,' accumulated from daily sleep deprivation, can lead to summer fatigue and decreased performance.

If you feel 'heavy-bodied in the morning' or 'can't shake off fatigue' despite having slept soundly, it might be a sign to reassess your bedroom environment. To transform your sleep time into 'recovery time' for the next day, it's effective not only to adjust air conditioner settings but also to review bedding like mattresses that directly touch your body, and to utilize the latest sleep gadgets that support comfortable sleep onset.

Now, before the full onset of tropical nights, is the perfect time to create an environment that supports comfortable sleep.

No Need for Immediate Purchase. Create a 'Comfortable Bedroom' with High-Quality Mattresses and Popular Gadgets

'It's a high hurdle to suddenly buy a high-quality mattress without knowing if it will suit my body.'

'I'm interested in a sleep gadget, but I don't know if it will really be effective for me.'

CLAS's mechanism, which allows you to 'rent, buy, and return' according to your lifestyle, resolves these dilemmas in choosing summer bedding and items.

With CLAS, you can try out highly breathable high-resilience mattresses, popular brand pillows, and the latest sleep gadgets on a monthly basis with low initial costs. If they don't suit your body or lifestyle, you can exchange them for another product or return them with just a smartphone. If they become your favorite items essential for daily sleep, you can purchase them while deducting the monthly fees you've already paid.

You can always optimize your sleep environment according to your life stage and seasonal changes.
