Sleep might as well be a performance enhancing drug. We rarely get enough and thus suffer from chronic deprivation. Adults that are able to achieve close to 8 hours a night of quality sleep see dramatic improvements in the following areas:
athletic performance – accuracy / speed
insulin / glucose / weight management
reduced pain sensitivity
We will take a closer look at six different clinical studies that have found sleeping an extra 1-2 hours per night over the recommended minimum level of 7 hours for adults can have significant benefits. Perhaps what is most concerning is just between the years 1998 – 2005 (we barely had smartphones) there was a 4% increase in people getting less than six hours of sleep per night.
Lower fasting blood sugar, insulin and weight loss have been found to occur with longer sleep durations. Three studies looked more into this. A 2014 NIH, 2015 from Belgium and a 2007 from UPENN. The physiological changes induced through chronically low sleep (< 7 hours per night) led to obesity, heart disease and mortality. Adequate sleep of 7-8 hours per night is vital.
