I get between 3 and 9 hours sleep a night, but I have really bad bags under my eyes. Why does this happen?

Dark Bags. Dark bags under eyes are often due to: fluid from thin blood vessels under eyes. This can be due to genetics (got it from mom or dad), excess rubbing (shiners), allergies, excess salt; be sure kidney function is normal. Cold ice packs might help decrease bags by constricting blood vessels. See an eyemd if no improvement. Some patients need to have excess skin removed. Eyedoc2020.Blogspot.Com.
