いつも寝る

You can use this phrase as a complete thought or part of a sentence. To make it sound more natural in conversation, you might say いつも寝ている. This adds the "ing" form, suggesting they are *currently* and *always* in that state. If you want to be polite, change it to いつも寝ます. If you are talking to a close friend, just いつも寝るね works perfectly. It is a very flexible phrase that fits into most daily conversations easily.

This phrase is perfect for casual observations. Use it when you are visiting a friend and their dog is asleep again. It is great for teasing a sibling who wakes up at noon. You can also use it to describe yourself during a boring holiday. "What did you do this weekend?" "I just always slept." It works well in texts when someone asks why you didn't reply. It is a relatable, low-stakes way to describe laziness or exhaustion.

Avoid using this phrase in a serious medical context. If someone has a sleeping disorder, いつも寝る sounds a bit too lighthearted. Also, be careful using it for your superiors at work. Even if your boss is dozing off, saying 部長はいつも寝る (The manager always sleeps) is quite rude. It implies they are lazy rather than just tired. For "going to bed" at a specific time, just use 寝る without いつも.

Japan has a unique relationship with sleep. There is a concept called 居眠り (inemuri), which is napping in public or at work. Interestingly, being "always sleepy" is sometimes seen as a sign of working too hard. However, いつも寝る is usually more about personal habits. It reflects the busy nature of Japanese life where sleep is a luxury. Many people catch up on sleep whenever they can, especially on trains or during breaks.

If you want to say someone is "always sleepy" instead of "always sleeping," use いつも眠い. If you want to emphasize they sleep *too much*, try 寝すぎ. For someone who specifically sleeps late into the morning, use 朝寝坊. You might also hear ずっと寝てる, which means "sleeping the whole time." Each variation adds a slightly different flavor to your description of their rest habits.
