Har du ett tips för att sova bättre när du känner dig stressad?

Because this is a yes/no question.

In Swedish, yes/no questions usually begin with the finite verb:

• Du har ett tips. = You have a tip.
• Har du ett tips? = Do you have a tip?

So Har du ... ? is the normal question pattern, similar to English Do you have ... ?

Because tips is a neuter noun in Swedish, so it takes ett in the singular indefinite form:

• ett tips = a tip

A useful thing to know is that tips looks the same in singular and plural:

• ett tips = a tip
• flera tips = several tips

The definite singular is tipset = the tip.

Here, för att + infinitive means to / in order to.

So:

• för att sova bättre = to sleep better / in order to sleep better

In this sentence, it describes what kind of tip you mean:

• ett tips för att sova bättre = a tip for sleeping better

This is a very common Swedish pattern.

Because bättre is the comparative form of bra.

The forms are:

• bra = good / well
• bättre = better
• bäst = best

So:

• sova bra = sleep well
• sova bättre = sleep better

This is an irregular pattern, so it is something you just need to learn.

När means when.

It introduces a time clause:

• när du känner dig stressad = when you feel stressed

So the sentence is talking about a situation: sleeping better when you are feeling stressed.

Literally, känner dig stressad is close to feel yourself stressed, but in natural English it simply means feel stressed.

This uses the reflexive verb pattern känna sig:

• jag känner mig stressad = I feel stressed
• du känner dig stressad = you feel stressed
• hon känner sig stressad = she feels stressed

So in this sentence:

• du känner dig stressad = you feel stressed

Because the subject is du, so the reflexive pronoun must match that person.

Reflexive forms are:

• jag känner mig = I feel
• du känner dig = you feel
• han/hon/den/det känner sig = he/she/it feels
• vi känner oss = we feel
• ni känner er = you all feel
• de känner sig = they feel

So sig is used for third person, not for du.

Yes, but the meaning shifts slightly.

• du är stressad = you are stressed
• du känner dig stressad = you feel stressed

Är stressad states the condition more directly. Känner dig stressad focuses more on the person’s experience or feeling.

In this sentence, känner dig stressad sounds natural because the question is about how someone feels and how that affects sleep.

Yes. Stressad is functioning as an adjective meaning stressed.

It agrees like other adjectives:

• en stressad person = a stressed person
• ett stressat barn = a stressed child
• stressade människor = stressed people

In du känner dig stressad, it describes du, so the basic form stressad is used.

A rough breakdown is:

• Har = have
• du = you
• ett tips = a tip
• för att sova bättre = to sleep better
• när = when
• du känner dig stressad = you feel stressed

So very literally, it is something like:

Have you a tip to sleep better when you feel stressed?

But the natural English version is:

Do you have a tip for sleeping better when you feel stressed?

Yes, it sounds natural and idiomatic.

It is a normal, neutral way to ask someone for advice. The tone is neither especially formal nor especially casual.

A Swedish speaker would easily understand it as a polite question asking for helpful advice about sleep and stress.
