כשהחדר חם מדי, אני יוצאת החוצה ושותה מים.

In Hebrew, the verb to be is usually left out in the present tense.

So:

החדר חם מדי
literally looks like the room too hot,
but it means the room is too hot.

In the past or future, Hebrew normally uses forms of להיות:

• החדר היה חם מדי = The room was too hot
• החדר יהיה חם מדי = The room will be too hot

כש means when. It often attaches directly to the next word.

So:

• כש + החדר → כשהחדר

This means when the room.

A more formal version would be כאשר החדר, but כש... is very common in everyday Hebrew.

In the Hebrew present tense, the verb usually shows gender and number, but not person clearly enough on its own.

For example, יוצאת can mean, depending on context:

• I go out
• you (singular feminine) go out
• she goes out

So אני is included to make it clear that the subject is I.

Because the speaker is female.

In the present tense, Hebrew verbs agree with the subject’s gender and number.

• אני יוצאת = I go out / I am going out said by a woman
• אני יוצא = the same, said by a man

So this sentence is from a female speaker’s point of view.

It actually does agree with gender, but in normal unpointed Hebrew writing, the masculine and feminine singular forms of this verb look the same.

With vowel marks:

• masculine: שׁוֹתֶה
• feminine: שׁוֹתָה

Without vowel marks, both are written שותה.

So in this sentence, שותה can still match a female speaker even though you do not see a different spelling.

מדי means too or excessively.

In Hebrew, it usually comes after the adjective:

• חם מדי = too hot
• יקר מדי = too expensive
• קשה מדי = too difficult

So the word order here is completely normal.

Yes, יוצאת already means goes out / leaves, but החוצה adds the idea of outside.

So:

• יוצאת = goes out / leaves
• יוצאת החוצה = goes outside

This combination is very common and natural in Hebrew, even if it feels a little repetitive from an English point of view.

Because the subject stays the same.

Hebrew often avoids repeating the subject when it is already clear:

אני יוצאת החוצה ושותה מים
= I go outside and drink water

Hebrew understands that the same I is doing both actions.

You could say ואני שותה מים, but that would usually add emphasis or contrast.

Most naturally, it sounds habitual or general:

When the room is too hot, I go outside and drink water.

Hebrew present tense can describe:

• something happening right now
• something that happens regularly
• a general pattern

Because of כש... here, the sentence is most naturally understood as what I do whenever that situation happens.

מים is one of a few Hebrew nouns that have a plural-looking form but are commonly used as a mass noun.

So even though it looks plural, it usually just means water.

A useful thing to know is that when adjectives describe מים, Hebrew often treats it as plural in form:

• מים קרים = cold water

In your sentence, there is no adjective after מים, so you just see it as the direct object: drink water.

Not without changing the meaning.

• כש = when
• אם = if

So:

• כשהחדר חם מדי... = When the room is too hot...
• אם החדר חם מדי... = If the room is too hot...

כש suggests this is the situation that happens and what you usually do in response.
אם makes it more conditional or hypothetical.
