“Introduction To Sleep Studies” is a song by The Ohayogozaimas. It was released August 26, 2016 as the first single for their album No-Nonsense. The music video for the song was made by UNE. As of 2023, this song has 68,000 views on YouTube. It was featured on the compilation album BRAT PACK 2017.

The song's lyrics are about the importance of sleep and come across as a lecture for a secondary school course.

The song is 4 minutes, 18 seconds long. It begins with an alarm clock sound effect as guitar feedback brings the song to a start. The song has a rising and descending motif to it. The main riff is played on bass guitar and accompanied by a scream by Saba. The main riff is repeated in a proper way, The second half of the verse has a call and response section with Saba and Nagi. The chorus of the song is also structured in a call and response sort of way, this time with Utsu-P and Saba. The second verse replaces the first section with a breakdown-esque section. After the second chorus, the pre-breakdown buildup starts, featuring Utsu-P doing some sort of strange harmonic sound with his bass guitar. The breakdown is based around a sustained dissonant chord. The breakdown feels like it destroys the song, so the post-breakdown section feels like it builds the song back together as the held chords are more melodic this time around. The chorus plays one more time, and the song ends with a loop of the main riff, it incorporates the breakdown's riff for the final notes.

The album version from No-Nonsense is a different recording. It's a subtle difference, but the most obvious change is the re-recording of the “go to bed” line which starts the breakdown

An instrumental version was featured on Tokuten

The backing track used for live performances was featured on tokunivv

前時代を踏襲しただけの美徳
ビル街の陋習にただ疲弊して
赤提灯ぶら下がってブラックアウト
やってばっか
そんな寝相じゃ取れん疲労感

枕固め 真っ暗　豆電
安堵感ごと羽織って布団
ひねもす蓄積しては忘す鬱積
就寝で解消

グッドモーニングな合図で覚めたい
午前中にはスカッと

万物は寝る 万物は寝る 万物は寝る
万物は寝る 家で
絶え間が無くては生存不可能さ
就寝せよ
万物は寝る 万物は寝る 万物は寝る
万物は寝る 家で
憂しと見し世ぞ 寝れば解放さ
睡眠が足んない

入眠と同時に 「今日」が死す
弔う間もなく 明日へ

今日の罪 徳も積み
敢闘の残骸持ち越して
晴れない闇は 宵越しで晴らす
最小単位の輪廻転生だ

グッドモーニングな合図で覚めたい
午前中にはスカッと

万物は寝る 万物は寝る 万物は寝る
万物は寝る 家で
絶え間が無くては生存不可能さ
就寝せよ
万物は寝る 万物は寝る 万物は寝る
万物は寝る 家で
猪口才な拙論はいらん 寝よう
それが睡眠学概論

Go to bed

くだらない生涯の三割を占める夢
七割を闘う為に全身全霊で眠れ
眠れ

万物は寝る 万物は寝る 万物は寝る
万物は寝る 家で
絶え間が無くては生存不可能さ
就寝せよ
万物は寝る 万物は寝る 万物は寝る
万物は寝る 家で
憂しと見し世ぞ 寝れば解放さ
睡眠が肝要 今日もまた始まる
全ては布団から

The virtues of just following the previous era,
I'm exhausted from the bad habits of the downtown high rise area
And tired of
the hanging red lanterns and blacking out all the time
You won't get that kind of fatigue if you take a sleeping posture

A fitted pillow, pitch black, night light,
and a sense of relief from laying on the futon
The anguish which accumulates throughout the whole day disappears
It's cancelled by going to bed

I want to wake up with good morning signs,
To wake up in the morning feeling relieved

All things sleep, All things sleep, All things sleep
All things sleep at home
Without these breaks, there is no survival
Go to bed
All things sleep, All things sleep, All things sleep
All things sleep at home
Sleeping will relieve your anguish and worldview
You don't get enough sleep

As soon as you fall asleep, “today” days
and tomorrow starts before you have time to mourn it

Carrying today's load of sins and virtues
over the ruins of a brave fight
The darkness which will not dispel can be dispelled throughout the night
Using the smallest unit of the endless circle of birth, death, and rebirth

I want to wake up with good morning signs
To wake up in the morning feeling relieved

All things sleep, All things sleep, All things sleep
All things sleep at home
Without these breaks, there is no survival
Go to bed
All things sleep, All things sleep, All things sleep
All things sleep at home
You don't need your bad habits, impertinence, poor arguments, go to sleep
That is the introduction to sleep studies

Go to bed

30% of our lives are taken up by nonsensical dreams
So sleep with all your might to fight that remaining 70%
Sleep

All things sleep, All things sleep, All things sleep
All things sleep at home
Without these breaks, there is no survival
Go to bed
All things sleep, All things sleep, All things sleep
All things sleep at home
Sleeping will relieve your anguish and worldview
Sleep is essential, It starts again today
It all starts on the futon

1. “hanging red lanterns” is in reference to cheap bar/restaurants which open at sundown, and close before morning.
