About Us

Hibernation Sleep MN in the Saint Anthony Park neighborhood of Saint Paul, Minnesota, is a practice dedicated to providing treatment for those looking to deepen their sleep to the level of “hibernation” so that they can wake up feeling refreshed, rested, and ready to tackle the opportunities of a new day. Led by sleep apnea dentist Nathaniel Cogswell, DDS, DABDSM, the Dr. Cogswell received his dental degree from the University of Minnesota and was prompted to delve into the world of dental sleep medicine while studying the effects of the airway on tooth and jaw position and development. The more he learned about sleep apnea, the more he became committed to helping others receive treatment for this life-limiting disease. He has committed to learning all he can about sleep apnea and dental sleep medicine to provide the best treatments with the best equipment for his patients.

Dr. Cogswell is a member of the Minnesota Sleep Society, a Diplomate with both the American Board of Dental Sleep Medicine (ABDSM) and the American Sleep and Breathing Academy (ASBA), and a Fellow with the International Academy of Sleep (IAOS).

Dr. Cogswell and the Hibernation Sleep MN team offer several solutions for individuals affected by conditions like chronic fatigue, insomnia, sleep apnea, and snoring. Focusing on non-invasive treatment alternatives to CPAP treatments, the team provides several oral appliances and sleep apnea mouthpieces. These are custom made from digital scans of your teeth and selected based upon what will be most comfortable for your mouth.

 We offer complimentary (no-charge) initial consultations and are always looking to educate patients on sleep-breathing options as well as help with referral options & resources. Our team is dedicated to helping you achieve better quality sleep.
