Cat Nap Challenge!
Take a cat nap or two this week. There is much debate on whether cat naps, also known as power naps, are helpful or harmful to us. Some people believe a cat nap gives them more energy for the day. Others think it leaves them feeling groggy, or makes it difficult to sleep at night. Simply try cat-napping to see if it positively effects your day, or negatively affects your sleep at night.

A true cat nap is only 10-30 minutes (ideally between 1:00 PM and 4:00 PM).  A longer nap than 30 minutes may leave you feeling tired when you wake up.

Research finds a six minute cat nap can improve declarative memory which is a type of long-term memory associated with the ability to recall facts and knowledge (Lahl, Wispel, Willigens and Pietrowsky, 2008)

Test a short napping session this week to see if it improves your day!
