Have you ever woken up after several hours of sleep to find yourself still groggy? I have.
It’s intuitive to think that a long sleep should leave you feeling regenerated and refreshed but in reality, it’s not just about the amount of time you spend asleep; it’s about the quality of that sleep as well.
A study done by the Sleep Foundation found that although the average American sleeps for 7 hours and 36 minutes each night, 35% report their sleep quality as ‘poor’ or ‘only fair.’
20% of the Americans surveyed said they did not wake up feeling refreshed during the week prior to the study.
