For many families, secrets are no longer the heart of the home, says counselling psychologist Nikole Seele.
Seele says that, in some cases, family secrets have been the foundation of many close 'insider' relationships and connections.
However, keeping secrets has layered consequences - no matter how good the intention, she says.
Seele explains that there is an important distinction between privacy and secrecy - the latter involves deception.
According to Seele, secrets exist because individuals fear judgment and shame.
People fear being judged, even if it's a perceived judgement or uncertainty around the potential to be judged, we have that fear.— Nikole Seele, counselling psychologist
She advises that secrets require a great deal of mental effort and can sometimes have a negative impact on our brain function or lead to anxiety and physical strain.
Keeping a secret is a mentally challenging task... It puts people into a state of stress response.— Nikole Seele, counselling psychologist
Seele explains why both transparency and privacy matter and how secrecy can do more harm than good.
She also responded to several questions and comments from callers who shared their personal experiences.
I'm now 42 years old, I was 24 when I found out from a third party that I am adopted. Everybody in the family kept it a secret. It almost threatened to break up my family and my marriage. It still affects me.— Daylan, caller
I think secrets should be banned in families. I grew up in a big family with a whole lot of secrets and every time they came out, they hurt people severely.— Lynette, caller
I have twins who are 12 and I'm married. My kids don't know that my husband is not their father.— Zanele, caller
