Most people know the dangers of drinking and driving, but think nothing of getting behind the wheel after a sleepless night. But the daytime effect of little or no sleep can hinder your driving skills to the point where you're impaired as if you've had too much to drink.
According to experts, chronic insomnia affects one in 10 people. And while insomnia can affect your safety and the quality of life during the hours you're awake, it can also increase your risk for a variety of other health problems. In addition to causing daytime fatigue, insomnia increases your risk for other health problems, including:
- Heart disease
- High blood pressure
- Intestinal problems
- Early death
In addition, people with insomnia are more likely to:
- Miss work
- Make bad decisions
- Take more risks
- Have trouble concentrating
- Be irritable
- Be depressed
- Eat foods high in calories
You Don’t Know What You’re Missing
Sleep affects our ability to think, react, remember, and solve problems. The catch is that we may develop some tolerance to lack of sleep and aren’t aware how much our alertness and performance is really suffering.
''Fatigue'' vs. ''Sleepiness''
It’s important to distinguish insomnia-related daytime fatigue from excessive daytime sleepiness (EDS). The terms are often used interchangeably, even among medical researchers. There are distinct differences, however.
People with EDS feel very drowsy during the day. They’ll typically fall asleep during the day if they’re in a boring or sedentary situation. They might fall asleep while stopped at a stoplight or sitting in a waiting room. EDS is usually caused by sleep apnea, sedatives, or narcolepsy.
People with daytime fatigue usually don’t fall asleep during the day, but they are very tired. They struggle to get through a normal day’s activities. Symptoms of daytime fatigue include:
- Weariness, weakness, and/or depleted energy
- Lack of motivation
- Poor performance
- Memory problems
- Lack of productivity
- Prone to errors and mistakes
- Low interest in being social
Fatigue is a more accurate description of what people with insomnia experience. Although they’re sleep deprived, they tend to feel more tired than sleepy. If you have insomnia, you might find it hard to nap. People with insomnia usually see a doctor because of fatigue and poor daytime functioning, not because they have trouble falling or staying asleep.
