Are you calm as a cucumber or do you feel ready to explode at any minute?
According to scientists at the University of British Columbia Okanagan, feeling irritable may be a sign that you're suffering from more serious underlying conditions.
In a study of more than 1,000 volunteers, the researchers developed five questions to assess how irritable participants were.
You can take the test for yourself below:
The Irritability Test:
Answer each of the following questions with "yes" or "no":
1. I have been grumpy
2. I have been feeling like I might snap
3. Other people have been getting on my nerves
4. Things have been bothering me more than they normally do
5. I have been feeling irritable
If you answered "yes" to each of the five questions you fall into the category of "being irritable".
According to the scientists, if you're deemed irritable it also means you may be suffering from other underlining mental health issues, including depressive symptoms, anger, hostility and neuroticism.
“We don’t know a lot about irritability yet, but since we know there could be consequences to irritability, it’s something that could likely benefit from treatment,” psychologist Susan Holtzman told NYMag.com.
“So if we can isolate irritability we can perhaps develop treatments that are best targeted towards people that are particularly irritable.
"Somebody could be very depressed but have no symptoms of irritability — on the other hand, someone could have depression and the prominent emotion may be irritability more than sadness. And you’d likely want to treat those two people in different ways.”
The good news is that Holtzman believes short term irritability is largely down to a lack of sleep. So if you're feeling cranky, get an early night and you may be smiling in no time.
