Not Getting Enough Sleep?

Reviewed by Melanie Blake, MD, MBA


Did you know that sleep deprivation affects around one-third of American adults? The body experiences sleep deprivation due to not getting enough sleep. On average, most adults need between 7-9 hours of sleep.


There are several types of sleep deprivation that an individual can experience.

  1. Acute sleep deprivation is usually a few days or less when a person has a significant reduction in their sleep time.
  2. Chronic sleep deprivation is diminished sleep that persists for three months or longer.
  3. Chronic sleep deficiency or insufficient sleep is ongoing sleep deprivation as well as poor sleep due to sleep fragmentation or other disruptions.


Many factors cause a person to experience sleep deprivation, such as poor sleep hygiene, lifestyle choices, work obligations, sleep disorders, and other medical conditions. Sleep deprivation presents itself through the following symptoms.

  • Slowed thinking
  • Reduced attention span
  • Worsened memory
  • Poor or risky decision making
  • Lack of energy
  • Mood changes
  • Weight Gain


These symptoms vary by person, but typically the symptoms depend on the level of sleep deprivation experienced. Coffee and energy drinks can mask the symptoms of sleep deprivation. It is essential to recognize how you feel on caffeine and off caffeine.

Sleep deprivation can contribute to a multitude of health problems. Those health problems include the following:

  • Cardiovascular disease
  • Diabetes
  • Obesity
  • Immunodeficiency
  • Hormonal abnormalities
  • Pain
  • Mental health disorders
