In today’s world, we are surrounded by innovative technology that helps us speed up our day to day lives. We can now communicate, learn, and process information faster than ever. As people’s daily tasks become faster, it seems less time is focused on other important tasks. Many people today are so focused on their busy lives and work schedules, that they are beginning to neglect an important process of the body known as sleep. Sleep is not only a vital process but it also helps the body restore from injury or illness, process information and memories, and renew cognitive brain function.
