There are 100 or more types of sleep disturbances/disorders.
Due to a variety of life’s circumstances, many people worldwide have sleep disturbances at one time or the other during their lifetime. But not all sleep disturbances will constitute a major sleep disorder like insomnia.
Insomnia is the most common sleep disturbance that is typified by difficulty falling asleep, staying asleep, and having a refreshing and satisfying sleep despite ample opportunity for a good sleep.
To diagnose insomnia, you must have the typical features described above for at least 3 nights per week and for a period of 3 months.
So, how do you know whether you are at risk for a major sleep disturbance like insomnia?
Research studies in Africa and other countries of the world like the USA have identified these three major independent predictors for insomnia in older adults as follows:

Women are 2 times more likely to suffer from insomnia than men. The reasons are multifactorial and include the fact that women are more exposed to social and economic stress, family related chores, hormonal changes and mood dysregulation, etc.

Physical illnesses like Coronary heart disease (CHD) and non-infective and infective diseases especially in Africa such as malaria, HIV/AIDS, sleeping sickness and tuberculosis have been identified as predictors for insomnia.
Malaria, HIV/AIDS, Sleeping sickness and Tuberculosis are common in most African countries and rare in high income countries of the northern hemisphere. The mechanisms for how an illness causes insomnia is complex, but may include presence of high levels of inflammatory factors in blood of the ill patient, reduced immunity and dysregulation of brain chemicals regulating the sleep-wake cycle, etc.

Research has established a connection between sleep disturbance and depression. It has been reported that people with insomnia have a 10 times greater risk of developing depression compared to those who have normal sleep nightly. Among people with depression, 75% have trouble falling and staying asleep.
So, whether your sleep disturbance is causing you to feel depressed or an existing depression is causing your sleep disturbance, recognise that there is a link between the two and get help early from your doctor or other caregivers.
Other contributing factors to insomnia include if you:
Remember, insomnia is treatable in the short and long term with behaviour therapy and physician prescribed medications as needed. So, being aware of the predictors and symptoms of insomnia and getting help early before the condition becomes chronic is vital to having better sleep quality and quality of life.
