What are the good points of taking cold showers compared to taking warm showers? Does it help stop frizzy hair? Does it help stop dry skin? Does it help smoothen your skin? If so, how do I get use to taking cold showers?

i dont have a bedframe for my bed and want to get the matress off the floor. i bought bed risers but they are for bed frames not for the matress it self. can i srick anything under there that will lift it off the floor. cardboard boxes wont hold... anything i can buy at the store?

ANY MEN ONLY !!! The thing is I am always busy to take showers so in winter I only take 3 per week. Does a shower take an hour?

I know its important, but WHY is it important? For example, what if everyone took 4 minute showers? How would things be different? How would it help? Alirght, most of you are saying "shorter showeres save water." So let me ask this: how does saving water help the environment? Water is renewable isn't it?
