During this summer's Olympics, several active people have commented on mental illness.

One of them is the American gymnast Simone Biles, who withdrew from the team final to focus on her mental well-being.

Home star Naomi Osaka has also been open about her mental illness.

A big step according to Linus Thörnblad, who was 25 years old when he ended his career after going into a fatigue depression.

- Just over ten years ago, I went into a fatigue depression and I had to work for many years to come back.

- When I went through it the most, there was no one who talked about mental illness.

Now, ten years later, the great athletes like Simone Biles and Naomi Osaka are talking about it - in the middle of an Olympic game.

It is very strong, he says in Morgonstudion.

"Openness is good"

Carolina Lundqvist is a performance psychologist and is on site in Tokyo for the Swedish Olympic team.

She notices that the discussion about mental illness has changed.

- That people talk about it is in line with what we have seen in recent years.

More and more people go out and talk about mental illness, says Carolina Lundqvist.

She believes that a large part is about pressure and expectations - both from oneself and from others.

- A lot in my job is about preparing the athletes.

To provide the tools and strategies for dealing with different situations.

- I think the openness is good.

Talking about these issues can make others seek help.

It should be okay to say that you do not feel so good, says Lundqvist in Morgonstudion.
