One third of the population suffers from some form of insomnia. Additionally, 10 percent of the population has insomnia at any given time. This sleep disorder is indicated by three main problems: difficult to fall asleep, difficult to remain asleep and waking up at night and finding it hard to go back to sleep. Most people with insomnia suffer from two of these three problems, while others suffer from all three problems. The resulting inadequate sleep leads to a chronic feeling of tiredness 1.
Most cases of insomnia are caused by stress, anxiety, depression, death of a loved one, some medications, caffeine and other sleep problems. In some instances, insomnia has no known causes, in which case it is called primary insomnia. You might be suffering from the disorder if you have some of the following 10 insomnia symptoms.
Symptom #1: Daytime Sleepiness
If you feel sleepy during the day, you could be suffering from insomnia. When you don’t get adequate sleep during the night, your body and brain are not well rested. This means that the sleepiness that you feel is your body’s way of letting you know that it needs to rest.
Sleepiness can be a serious problem especially if you are involved in activities requiring optimal concentration like driving or operating sensitive equipment. It is estimated that sleepiness may be responsible for 100,000 auto accidents and up to 1,550 deaths annually. Studies also show that sleepy workers are more prone to job-related accidents.
