Hi, I know there are some very intelligent people that have some very high degrees that come to these forums who have probably studied for 15+ hours a day after day after day... My question is if it's really bad for your health to study to much, similar to exercising to much. I can't seem to find any studies that show studying to much is bad for your health. I plan on exercising 6 days a week, normally I run 3 miles a day and then the next day switch to 5 and than just repeat. So i figure if I exercise for a hour a day, have to take a shower, spend 3 hours attending lectures, spend 2 hours eating going to the bathroom, sleep for 4 hours a day, maybe try to get 5 or 6... I potentially have the ability to study for I could study 12 hours a day during the school week monday through friday, and than study 15 hours a day on the weekends... I haven't been able to find any research or studies that show that doing so is bad. Can you like permantly hurt yourself by doing so? also how many hours would you say are needed of studying on your own for a undergraduate course, like 100 hours per credit?
