How Sleep Affects Your Brain

Why your brain needs sleep infographic

Sleep is important. All of us, newborns and adults alike, need sleep in order to function properly. Both the number of hours you sleep at night (and the quality!) are critical for your mental well being.

Researchers explain how sleep affects the brain:

How Sleep Affects Memory

  1. Lack of sleep impairs a person’s ability to focus and learn efficiently.
  2. Sleep is necessary to consolidate a memory (make it stick) so that it can be recalled in the future.

How Sleep Affects Judgement

Sleeplessness impairs the ability to evaluate situations correctly, make rational decisions and correct choices. When lacking sleep, adolescents are 33% more likely to engage in risky behavior.

How Sleep Affects Mood

Sleep deprivation interferes with the body’s ability to create serotonin, the hormone that acts as a mood stabilizer. 75% of adults whose sleep is affected by stress say that sleep problems also increased their anxiety. 54% say that stress increased their anxiety about falling asleep at night. 52% of men reported a lack of sleep altered their ability to remain focused the next day. 42% of women reported sleep deprivation caused lack of focus the following day.

How Sleep Affects Creativity

Sleep is ideal for brainy maintenance. There’s a natural need for neural networks in your body to occasionally go into a type of “maintenance mode.”

The mind needs to rest in order to make repairs, clean up any misfiring signals, and spark creativity.
