Oavsett om min rutin på morgonen är lugn eller stressig, försöker jag dricka vatten.

Oavsett om means regardless of whether or whether ... or ....

In this sentence:

Oavsett om min rutin på morgonen är lugn eller stressig ...

it introduces two possible situations:

• the morning routine is lugn = calm
• the morning routine is stressig = stressful

So the idea is: no matter which of these is true, I still try to drink water.

This is a very common Swedish pattern:

• oavsett om X eller Y
• regardless of whether X or Y

In your sentence:

• om = whether/if
• eller = or

So:

• oavsett om min rutin på morgonen är lugn eller stressig

literally works like:

• regardless of whether my routine in the morning is calm or stressful

This structure is very natural in Swedish.

This is because Swedish follows the V2 rule in main clauses: the finite verb usually comes in the second position.

The sentence begins with a fronted clause:

• Oavsett om min rutin på morgonen är lugn eller stressig

After that, the main clause starts, and the verb must come before the subject:

• försöker jag dricka vatten

So the order is:

1. introductory clause
2. finite verb = försöker
3. subject = jag

This is very normal Swedish word order.

Compare:

• Jag försöker dricka vatten.
• På morgonen försöker jag dricka vatten.
• Oavsett om ... försöker jag dricka vatten.

The comma after stressig helps show the pause between the introductory clause and the main clause:

• Oavsett om min rutin på morgonen är lugn eller stressig, försöker jag dricka vatten.

In Swedish, this comma is often a matter of style and clarity rather than a strict requirement in every case. Many writers would include it here because the opening clause is fairly long.

So the comma is natural and helpful, even if Swedish punctuation is sometimes a bit less comma-heavy than English.

In Swedish, på morgonen is the usual expression for in the morning.

• på morgonen = in the morning
• på kvällen = in the evening
• på natten = at night

So this is just the normal preposition used with parts of the day in this kind of expression.

Be careful not to confuse it with:

• i morgon = tomorrow

Those look similar but mean different things:

• på morgonen = in the morning
• i morgon = tomorrow

Because rutin is a common gender noun in Swedish, so it takes:

• en rutin
• min rutin

Not:

• ett rutin
• mitt rutin

So the possessive agrees with the noun’s gender:

• min bok
• min rutin

If the noun were an ett-word, you would use mitt instead.

They are describing rutin, which is:

• singular
• indefinite
• common gender (en word)

For that form, adjectives usually appear in their basic form:

• en lugn rutin
• en stressig rutin

So in the sentence:

• min rutin ... är lugn eller stressig

the adjectives stay as:

• lugn
• stressig

If the noun were an ett-word, you would often add -t:

• ett lugnt schema

And if it were plural or definite, the form could change again.

Because Swedish often uses vara (är) with adjectives to describe a state.

So:

• min rutin är lugn = my routine is calm
• min rutin är stressig = my routine is stressful

That is the most straightforward way to describe what the routine is like.

Other verbs are possible, but they would slightly change the meaning:

• känns lugn = feels calm
• blir stressig = becomes stressful

So är is the neutral, simple choice here.

Because vatten is being used as an uncountable substance in a general sense.

• dricka vatten = drink water

Just like in English, you normally do not need an article when talking about water in general.

You would add something if you wanted to be more specific:

• dricka ett glas vatten = drink a glass of water
• dricka vattnet = drink the water
• dricka lite vatten = drink some water

But in this sentence, general vatten is exactly right.

In Swedish, the present tense försöker can often cover both ideas depending on context:

• I try to drink water
• I’m trying to drink water

In this sentence, because it talks about a general habit and a morning routine, the natural interpretation is:

• I try to drink water

That sounds habitual, not just about one specific moment.

Yes, it is natural and understandable.

It means something like:

• my routine in the morning
• my morning routine

Swedish also has other natural ways to express a similar idea, for example:

• min morgonrutin = my morning routine

So both are possible. The version in your sentence is slightly more expanded, but it sounds fine.

In this sentence, it most naturally refers to mornings in general, because the whole sentence sounds habitual:

• Oavsett om min rutin på morgonen är lugn eller stressig, försöker jag dricka vatten.

That sounds like something the speaker usually does.

If the speaker meant one specific morning, the context would normally make that clearer.

So here, a learner should understand it as a general statement about the person’s mornings.

Oavsett is used to express the idea of regardless or no matter.

A few common patterns are:

• oavsett om ... = regardless of whether ...
• oavsett vad = regardless of what / no matter what
• oavsett hur = regardless of how
• oavsett vem = regardless of who

Examples:

• Oavsett vad du säger, kommer jag.
  = Regardless of what you say, I’m coming.

• Oavsett hur trött jag är, går jag till jobbet.
  = No matter how tired I am, I go to work.

So the sentence you gave uses a very common and useful pattern.

A learner often notices that oavsett looks long and slightly intimidating.

A few helpful points:

• It is pronounced as one word, not as separate pieces.
• The stress is typically on the final part: -sett.
• The v is pronounced normally.
• The double tt means the preceding vowel is short.

You do not need perfect pronunciation right away; the important thing is to say it smoothly enough that it sounds like one fixed expression:

• oavsett om

This combination is so common that it is worth practicing as a chunk rather than word by word.
