How many years of college studies are involved to become a somnologist?

There's no specific undergraduate degree called "somnology." To become a somnologist (a sleep technologist or sleep medicine physician), you need a different number of college years depending on the specific career path:

* Sleep Technologist: This usually requires an associate's degree (2 years) in a relevant field like respiratory therapy or a related healthcare area, followed by certification from a credentialing body like the Board of Registered Polysomnographic Technologists (BRPT).

* Sleep Medicine Physician: This requires a much longer path. It involves:

* 4 years: Bachelor's degree (pre-med)

* 4 years: Medical school (MD or DO)

* 3-7 years: Residency in sleep medicine (this can vary depending on the program and whether a general internal medicine or neurology residency is also required)

Therefore, the total years of college studies can range from 2 years for a sleep technologist to 11-15 years for a sleep medicine physician.
