Difference Between Sleepiness and Insomnia

Before learning the consequences of sleepiness and insomnia, you need to know the difference between the two. 

Sleepiness is what happens when you get less than the recommended seven hours of sleep. If you have a bad night or rest due to sickness or a crying newborn, odds are you wake up feeling drowsy and unproductive. Sleepiness is temporary, but in excess, it can lead to much worse. 

Insomnia is a diagnosable disorder that prevents someone from falling and/or staying asleep. Some people suffer from chronic insomnia and experience the symptoms for their whole lives. For others, stress or a big life change can trigger intermittent insomnia, which lasts for a short period of time. 

But can insomnia kill you? Studies show that people who suffer from persistent insomnia experience a much higher risk of death than those who get the recommended amounts of sleep.

Physical Consequences

Insomnia is dangerous, especially to your physical health. Below are just a few of the physical consequences that insomnia brings. 

Heart Conditions

A lack of sleep drastically affects your heart and insomnia can lead to a variety of heart conditions. 

Adults who suffer from insomnia have a higher risk of suffering from coronary heart disease. Lack of sleep produces higher blood pressure levels, which drastically affects one’s heart health. 

In addition to coronary heart disease, insomnia increases your risk of having a heart attack or stroke. 


Heart disease and obesity are often linked hand to hand, which means there’s a similar connection between insomnia and obesity.
