The numbers are in, and both Scottsdale and Mesa have made the list for the Top 10 Sleepless Cities in the U.S.

Chemistry.com, a popular online dating site for adults, recently conducted a study to determine the top 10 cities that produce the most traffic on its website between the hours of midnight and 6 a.m. The study accounted for the six different time zones in the country.

Honolulu topped off the list as the most sleepless city while Scottsdale placed fourth.  Mesa closed off the list as the tenth most sleepless city in the U.S. Other cities that placed in the top 10 include Virginia Beach, Nashville, Long Beach and Las Vegas.

Up All Night, Chemistry.comIn celebration of these recent findings, the dating website decided to host a special “Up All Night” event to help insomniacs who also happen to be looking for love. During the event, both new and current members can access the dating website free of charge from 9 p.m. to 6 a.m. CDT on Thursday, August 30. Participants will be able to browse full profiles with photos and communicate with other members on the site. They can also play special get-to-know-you games. New members will need to take the website’s unique personality test and create their own profile.

Match.com, another popular dating site, launched Chemistry.com in February of 2006. The dating website sets itself apart from others by bringing singles together “that are looking for ways to discover if true chemistry exists before meeting on the first date.” The website has all members take a special personality test developed by renowned biological anthropologist Dr. Helen Fisher. The test makes the “getting to know you” process much simpler than dating in person and allows users to connect with those who share their similar interests.

So if you’re awake, single and ready to mingle in the wee hours of the morning, be sure to check out the “Up All Night” event and meet some fellow Arizonan insomniacs.
