WARNING!
For people who are "underweight" it may be a good idea by slowly decreasing the temp. each time you take a shower, followed by taking your temperature afterward.
Core Temp. Side Effect
95 Shivering
90 Confusion
85 Lethargic
80 Coma
78 Death
Measuring the length of the shower is important, as the longer you expose your self to cold water, the lower your body temperature will drop.
I hope this helps, and as always; if you think you may have an eating disorder, you may have one, or develop one!
