UNDERSTANDING mental health is becoming a greater issue in society as more is known about the hidden illness.

Unlike a broken ankle, it is hard to tell how much it is impacting somebody, and it doesn't discriminate with ages.

Queensland Health looked at the issue in a blog, higlighting the importance of parents connecting with their children on the matter.

Travis Maguire, manager of headspace Warwick, said there were ways parents can check in on the mental health of their children.

"There's a fine line between under and over doing it. It's only natural for parents to worry," he said.

"It can be hard for parents to sit back, so it is good to check in if they notice a change in behaviour.

"It can be as simple as asking how things are at school and at home. Keep it short and sweet.

"They'll know you're there. If it is overboard, it could mean they internalise or feel hounded.

Mr Maguire said schools in the area were doing more of a part to address mental health amongst students.

"Education is better than it was, and schools are doing a good job," he said.

"Last year we spent more time in primary schools than ever before.

"We were pleased. We threw questions at them about anxiety, and the answers they were feeding back to us were really insightful."

Maguire applauded the blog looking at talking about emotions, and said there were ways to communicate problems effectively.

One of these ways was the placement of red dots in areas of the house, where a child would be required to find the nearest one during a heated moment, and take deep breaths to help calm them down.

"Red dots give kids a chance to calm down, and still address the problem," he said.

"It can help to take the emotion out of an argument, give someone time to calm down, before coming back and talking.

"It's a two-way street. Kids can tell their parents to use the red dots as well."

The identification of early emotional development within children, as well as talking to reduce stigma around the topic, were also addressed in the blog.
