They refer to related but different things.

• 몸이 나아지다 = the body / physical condition gets better
• 몸살이 덜해지다 = the body aches become less severe

So in this sentence:

• 몸이 나아지는 중 focuses on your overall physical recovery
• 몸살이 조금 덜해졌어 focuses on one specific symptom improving

Using both is natural because Korean often states the general condition first and then the symptom.

Yes, literally it is something like the body gets better, but in natural English it usually means:

• I’m recovering
• My condition is improving
• I’m getting better physically

Korean often uses body-related subjects more directly than English does. So while English would usually say I’m getting better, Korean can say 몸이 나아지다 to focus on physical condition.

Both are related to getting better, but there is a nuance.

• 낫다 = to recover, to get well
• 나아지다 = to improve, to become better

In many situations they overlap, but 나아지다 often emphasizes gradual improvement or a change in condition.

So:

• 몸이 낫는 중 would sound more like I’m in the process of recovering
• 몸이 나아지는 중 sounds like my condition is improving

Because the second half says the body aches have become less severe, 나아지는 중 fits well with the idea of ongoing improvement.

-는 중이다 means to be in the middle of doing something or to be in the process of doing something.

So:

• 나아지다 = to get better / improve
• 나아지는 중이다 = to be getting better / to be in the process of improving

It highlights that the recovery is still ongoing, not fully complete.

Similar examples:

• 먹는 중이야 = I’m eating / I’m in the middle of eating
• 공부하는 중이야 = I’m studying / I’m in the middle of studying

Here, 몸이 나아지는 중 means the speaker is currently recovering.

중이라 comes from 중이다 plus a reason/connection ending.

The full form is basically:

• 중이라서 = because it is in the middle of...

In casual speech, -서 is often dropped, so:

• 중이라서 → 중이라

So 몸이 나아지는 중이라 means:

• because I’m in the process of getting better
• since my condition is improving

This shortened form is very common in conversation.

Because -는 중이다 attaches to the verb stem to show an ongoing action or process.

• 나아지는 중이다 = be in the process of improving
• 나아진 is a different form meaning that has improved or improved

So:

• 나아지는 중 = still improving
• 나아진 몸 = a body/condition that has improved

In this sentence, the speaker wants to say recovery is currently happening, so 나아지는 중 is the correct form.

몸살 refers to body aches, general body pain, or the kind of aching you get when you are sick or physically worn down.

It is not exactly the same as:

• 감기 = a cold
• 독감 = the flu

But 몸살 can happen along with those illnesses. It often gives the feeling of:

• aching all over
• soreness
• feeling physically beaten up

So in this sentence, 몸살이 조금 덜해졌어 means the aching has eased up a bit.

덜해졌어 comes from:

• 덜 = less
• 하다 = to do / to be
• 해지다 / 해졌다 = became / has become

In actual usage, 덜하다 means to be less or to be not so severe, and 덜해지다 means to become less severe.

So:

• 몸살이 덜해졌어 = the body aches got better / became less severe
• more literally: the body aches became less

It is a very natural way to talk about symptoms easing.

조금 means a little.

So:

• 덜해졌어 = it got less severe
• 조금 덜해졌어 = it got a little less severe

Adding 조금 makes the statement more precise and modest. It suggests improvement, but not a dramatic one.

That fits well with the first clause: the speaker is still recovering, not fully recovered.

덜해졌어 is in the informal casual style, often used with:

• friends
• family
• people you are close to
• diary-like or spoken narration

The polite version would be:

• 지금 몸이 나아지는 중이라 몸살이 조금 덜해졌어요.

So the meaning is the same; only the politeness level changes.

지금 means now / right now / at the moment.

It sets the time frame for the whole sentence:

• right now, I’m in the process of getting better
• as of now, the body aches have eased a little

Without 지금, the sentence would still make sense, but 지금 makes the current recovery status more explicit.

Yes, that is a very natural translation.

The Korean structure is a little different from English, but the idea is:

• 지금 몸이 나아지는 중이라 = I’m in the process of getting better now / since I’m getting better now
• 몸살이 조금 덜해졌어 = my body aches have eased a little

A few natural English translations would be:

• I’m getting better now, so the body aches have eased a little.
• Since I’m recovering now, my body aches are a little less severe.
• I’m in the process of getting better, so the aches have gotten a bit better.

Yes, you can, and it would sound natural too.

Compare the nuance:

• 몸살이 조금 나아졌어 = the body aches got a little better
• 몸살이 조금 덜해졌어 = the body aches became a little less severe

The first is a more general improved statement. The second focuses more specifically on severity decreasing.

So 덜해졌어 is a nice choice if you want to emphasize that the symptom is still there, just weaker now.

No. It strongly suggests the opposite: recovery is still in progress.

Two parts show that:

• 나아지는 중 = in the process of getting better
• 조금 덜해졌어 = got a little less severe

So the speaker is saying:

• I’m not completely well yet
• but I am improving
• and one symptom has eased somewhat

That gradual, partial-improvement feeling is an important nuance of the sentence.
