“It doesn’t matter if the glass is half empty or half full. Be thankful that you have a glass and grateful that there’s something in it.” – Unknown


Stop for a minute. Take 1-2 minutes right now and think about a couple things that you are thankful for today…It can be anything simple from having time to drink coffee, the wifi you are connected to, or more emotionally provoking things such as the health of family and friends, or the opportunity to have a fulfilling career, or just waking up on time this morning.

Robert Emmons, a professor of psychology at UC Davis, is one of the leading experts in the science of gratitude. He states gratitude can affect our physical and mental health, including that in can “lower blood pressure, improve immune function, facilitate efficient sleep, reduce lifetime risk for depression, anxiety, and substance abuse disorders.” Practicing gratitude can positively affect behaviors, such as by “engaging people to exercise more,” practice “better dietary behaviors,” and reducing people’s likelihood of smoking and abusing alcohol.  Gratitude creates a positive feedback loop due to the neurotransmitter dopamine, which help control the brain’s reward and pleasure center. Although this may sound too good to be true, consider the following additional findings.
