When you're busy with work and housework and keep pushing yourself to keep working, when someone thanks you for your hard work, you forget how tired you are and end up working even harder...Have you ever had this experience?

In fact, this does not mean that fatigue has disappeared, but rather that the brain is ignoring the fatigue.

Fatigue, like pain and fever, is an alarm that tells you something is wrong with your body.

However, if you ignore the alarm and keep working hard, feeling a sense of accomplishment, your brain will be less likely to feel tired.

However, the fatigue does not disappear but continues to accumulate, eventually causing insomnia, depression, and a decline in memory and concentration.

It is important not to overlook this accumulation of fatigue and to take care to relieve it diligently every day, both in terms of health and in order to continue to perform to your full potential at work and at home.

Why do I feel tired?

Fatigue is thought to occur when excessive physical and mental activity consumes large amounts of oxygen, which in turn causes cells to become oxidized and damaged, and slows down the metabolism that produces energy.

Fatigue can be divided into muscle fatigue caused by exercise and mental fatigue caused by factors such as stress that affect the brain.

While most muscle fatigue can be recovered with a night's sleep, mental fatigue does not fully recover with a night's sleep, and fatigue tends to become chronic.

It has been reported that 40% of Japanese people feel this type of fatigue has been continuing for more than six months.

What happens if you don't eliminate fatigue?

If fatigue is not alleviated, it can lead to strong feelings of anxiety over even minor everyday events, and sleep disorders such as difficulty falling asleep or waking up in the middle of the night due to shallow sleep. Fatigue can then become chronic, and before you know it, you may find yourself losing motivation, taking longer to do housework or work than before, or making repeated mistakes, leading to a decline in work efficiency. If chronic fatigue worsens, it can lead to depression and other conditions. Fatigue also weakens the immune system, which can increase the risk of lifestyle-related diseases such as cancer.

What can I do to recover from fatigue?

In order to recover from fatigue, damaged cells must be allowed to rest, repaired, and restored to their normal functions. Humans are naturally equipped with a fatigue recovery system, and three key factors in improving its functioning are "sleep," "diet," and "exercise."

It gently encourages rest for a tired brain

The trick to avoiding brain fatigue is to get quality sleep, change your mood effectively, and keep a positive attitude.

So, at Della, we have created an album called "Music for Relieving Fatigue," which is a collection of songs that help relax the brain and prevent fatigue from building up.

This CD was created under the supervision of a fatigue medicine expert, and after undergoing verification tests of mood measurement surveys and physiological indicators such as the autonomic nervous system.

The song is based on the idea that "the feeling of coming into contact with nature" is what most soothes the human mind, and is based on sounds that evoke nature, such as birdsong and the sound of a stream, creating a song that is pleasant to both the ears and the heart.

How to listen to CDs effectively

◎Throughout the album, the songs gradually transition from bright tones to calmer melodies, so if you want to get a sleep-inducing effect, we recommend listening to the album from the first track onwards.

◎When you feel tired, when you have been feeling tense or excited for a long time, or when you are taking a break from work or study, listening to your favorite songs will have a refreshing effect on your mood.

◎ Listen without getting ready to listen, but instead let yourself be carried away by the music in a natural way.
