I can track references for these if you need them. Dennis -----Original Message----- From: Rob Weisskirch [mailto:[EMAIL PROTECTED] Sent: Thursday, February 26, 2004 12:34 PM To: Teaching in the Psychological Sciences Subject: Tanning beds and seasonal affective disorder TIPSfolk, I was discussing Seasonal Affective Disorder and the relationship to melantonin, serotonin, and sunlight. A student asked if the same effect of full-spectrum lighting could be achieved by going to a tanning salon. I think that tanning salons use lights that block UV rays, but I don't know the relationship of the properties of sunlight that actually prompt melantonin and serotonin production. Can anyone help clarify this?
