28 Dec How Important Is Sleep?

How important is sleep? Deadly important! And I mean that literally. This is one of the best podcasts I have listened to this year.

A few highlights below:

Sleep Facts from Matthew Walker, Professor of Neuroscience and Psychology at Cal Berkeley for individuals who get less than 7 hours of sleep.
• You are more likely to eat processed carbs and sugars. This can lead to weight gain, diabetes, etc.
• The prefrontal cortex (the rational/logical part of the brain) gets switched off. These sections of the brain are responsible for emotions erupting. This makes you less productive at work and increases the likelihood of emotional overreactions.
• Immune system is weakened. A weakened immune system increases the likelihood of cancer and Alzheimer’s.

How important is one extra hour of sleep?
• Spring: (-1 hour of sleep) showed a 24 % increase in heart attacks.
• Fall (+1 hour of sleep) showed a 21% decrease in heart attacks.
