湯加減（ゆかげん） means the temperature/comfort level of the bath water.

• 湯 = hot water, especially bath water
• 加減 = degree, condition, adjustment

So 湯加減を確認した means checked how the bath water felt / checked the bath temperature.

It is a set expression often used when talking about baths, not just water in general.

Because 湯加減 is the direct object of 確認した.

• 確認する = to check / confirm
• You check something
• That something takes を

So:

• 湯加減を確認した = checked the bath temperature

This is very straightforward object marking.

Here, が means but or although.

So:

• 確認した = checked
• 確認したが = checked, but...

This が connects the first part of the sentence with a contrasting or unexpected result in the second part.

It often sounds a little softer or more narrative than a plain English but. In this sentence, the idea is something like:

• Even though I checked the bath temperature, ...
• I checked the bath temperature, but ...

Because it describes an event that happened before the later events in the sentence.

The sentence is narrating a sequence:

1. 湯加減を確認した
2. 湯上がりにのぼせて
3. 湯冷めして
4. 卓球をしなかった

Japanese often uses the past form in storytelling to describe completed events, just as English does.

湯上がり（ゆあがり） means after getting out of the bath or just after a bath.

Then に marks the time when something happens.

So:

• 湯上がりにのぼせて = became overheated/lightheaded after the bath

You can think of に here as a time marker, similar to:

• 朝に = in the morning
• 食事の後に = after the meal
• 湯上がりに = after getting out of the bath

のぼせる means to become flushed, dizzy, faint, or overheated, especially from hot water, heat, or staying in the bath too long.

So のぼせて means:

• becoming overheated
• getting dizzy/flushed from the bath

This is a very bath-related word in Japanese. It is commonly used when someone stays in hot water too long and feels unwell afterward.

The て-form here links this part to what follows.

In this sentence:

• のぼせて
• 湯冷めして
• 卓球をしなかった

The て-form can connect actions or states in a sequence, and it can also suggest a reason/background.

So the feeling is something like:

• I got overheated, then got chilled, and as a result I didn’t play table tennis.

It is not just a list of separate facts. It gives a flow of events leading toward the final result.

湯冷め（ゆざめ） means getting chilled after a bath.

So 湯冷めして means:

• got chilled after the bath
• caught a chill after bathing

This is a very specific Japanese word. It refers to your body cooling down badly after being warm from bathing.

It is different from just saying 寒くなった (got cold) because 湯冷め specifically relates to cooling off after bathing.

They are different conditions, and yes, they point in different physical directions:

• のぼせる = overheated / flushed / dizzy from heat
• 湯冷めする = get chilled after the bath

The sentence is saying both happened in succession or as part of the aftermath of bathing. It may sound a bit dramatic, but it is grammatically fine: first the person got overheated from the bath, then later cooled off too much and felt chilled.

Japanese often strings together multiple states like this to explain why the final action did not happen.

Both are possible.

• 卓球をしなかった
• 卓球しなかった

The version with を is a little more explicit because 卓球 is being treated clearly as the object of する.

Japanese often does this with activity nouns:

• 勉強をする
• 運動をする
• 卓球をする

In casual speech, the を is often dropped:

• 勉強する
• 運動する
• 卓球する

So 卓球をしなかった is perfectly normal and a bit more fully marked.

Yes, the subject is omitted, which is very common in Japanese.

The sentence does not explicitly say I, he, she, or they. Japanese often leaves the subject unstated when it is clear from context.

The natural assumption is that the same person did all of these things:

• checked the bath
• got overheated
• got chilled
• did not play table tennis

In an isolated sentence, English learners often imagine I or he/she, but the real subject depends on the surrounding context.

A useful way to break it up is:

• 湯加減を確認したが、 = I checked the bath temperature, but...
• 湯上がりにのぼせて、 = after the bath, I got overheated...
• 湯冷めして、 = then got chilled...
• 卓球をしなかった。 = and did not play table tennis.

So the sentence has:

1. an initial clause ending in が for contrast
2. two linked て-form parts showing intermediate events/states
3. a final main clause

This is a very common Japanese pattern for telling a chain of events.

No. 湯上がり is a noun.

It comes from:

• 湯 = hot water / bath
• 上がり = rising/getting out

In bath-related expressions, 上がる can mean to get out of the bath. So 湯上がり means the state or timing of having just gotten out of the bath.

That is why it can be followed by に:

• 湯上がりに = after getting out of the bath / just after a bath

Usually but is the better choice here.

が often introduces contrast, unexpected continuation, or a setup that leads to a result the speaker wants to highlight. In this sentence, the feeling is:

• I checked the bath temperature, but even so, things went badly afterward.

Using and would weaken that contrast too much.

So while translation always depends on context, but or although fits this sentence best.
