Missing out on the recommended 7 to 9 hours of shut-eye nightly does more than make you feel groggy and grumpy. The long term effects of sleep deprivation are real. It drains your mental abilities and puts your physical health at real risk. Science has linked poor slumber with all kinds of health problems, from weight gain to a weakened immune system.

In the short term, a lack of adequate sleep can affect judgment, mood, ability to learn and retain information, and may increase the risk of serious accidents and injury. In the long term, chronic sleep deprivation may lead to a host of health problems including obesity, diabetes, cardiovascular disease, and even early mortality.

The obvious signs of sleep deprivation are:

  • excessive sleepiness
  • yawning
  • irritability
  • daytime fatigue

You may also end up experiencing microsleep in the day. During these episodes, you’ll fall asleep for a few seconds or minutes without realizing it. Microsleep is out of your control and can be extremely dangerous if you’re driving. It can also make you more prone to injury due to trips and falls.
