There is nothing wrong with your chakras being open. It is helpful if you open and work with all seven of them. It is believed that if one of them is blocked or not working properly it can actually cause you to become ill more easily, depressed, etc. A lot of healing practices (crystal healing and color therapy for example)are based around the idea that these chakras are associated with certain colors and energy vibrations, thus, the corresponding color is placed on or over the chakra area to promote proper energy flow and chakra function.
If you look around the site, there are several articles on working with and opening the chakras. I have provided a link to one of the ones in the featured articles section of the site.
