Wait and see An excellent example by the Asker of having 'is i magen'.

Landsknecht (asker) Dec 4, 2018:

I think I must explain why I did not select the best answer. The target language was Russian, and all the suggested translations were equally good in helping me to find a Russian equivalent for the phrase. It was difficult to select, so the automatic system decided instead of me.

Right Chris, As long as it was the right key! ;-)

Christopher Schröder Oct 30, 2018:

Ice cream? When I was a musician, having plenty of alcohol in my stomach was key.

@Michele and all "Doesn't get into a flap". "Doesn't get their knickers in a twist".
Not only context but register is needed for this expression too

Michele Fauble Oct 28, 2018:

'ha is i magen' 'have nerves of steel' - but it really depends on the context.

SafeTex Oct 28, 2018:

@all Oops, I thought we were on the Swedish to Swedish group so I gave a Swedish expression by mistake. Sorry about that
It would be nice to know if there is a context to this question in order to choose the best solution this time round.
"Stay cool" kind of brings up a picture of a guy with long hair and sun-glasses whereas "keep a level head" is more "businesslike".
Other similar expressions would suit other similar situations but what is the asker's situation?
