How is sleep deprivation different from insomnia?

Sleep deprivation happens when you don't get enough sleep, while insomnia is when you have trouble falling or staying asleep even if you have the chance to sleep.

Explanation

Sleep deprivation and insomnia are two different sleep problems. Sleep deprivation means you don't get enough sleep because of things like staying up too late or having too much to do. This can make you tired and less alert during the day.

On the other hand, insomnia is when you have trouble falling asleep or staying asleep, even if you have time to sleep. People with insomnia might feel tired during the day, even if they tried to sleep enough hours.

According to the medical literature:

  • Sleep deprivation is often a choice or due to circumstances, while insomnia is a sleep disorder.
  • Insomnia can affect how well you pay attention and stay alert, similar to sleep deprivation.
