Lack of sleep can cause mental illness – Expert

People who do not give priority to sleeping for at least seven to eight hours, or take a nap during the day, are vulnerable to mental illness.

A clinical psychologist, Dr Egbe Otu of the Federal Neuro-Psychiatric Hospital, Calabar, further warned that lack of sleep exposes the brain to accumulation of certain ‘neuro chemical debris’.

The mental illness expert spoke in a presentation he made to journalists during the 2025 Media Week celebration in Calabar.

He particularly advised journalists to give themselves adequate time for mental rest and sleep.

“Those of you who are given to mental energy exertion, including journalists who are always in a hurry to meet deadline or browse the net using technological devices are at risk.

“You must find time to sleep frequently. It is very good to take a nap even for ten or 15 minutes. This helps to regulate or restore some mental chemicals. You must sleep for at least eight hours. This is very important.

“Sleep helps to adjust or maintain your mental health for good,” Otu stressed.

According to him, mental health issues abound in the environment.

Noting that mental health problems have many causes, he advised that phones and computers should be used sparingly.

He also disclosed that lack of housing, unemployment and exploitation are other factors that cause mental disorders.

Otu advised that people should regularly approach mental experts for regular checks and advice.
