Re: groe @ night.....growing pains ?????????
Because of the affects from the nights before. Your body will cool down during the day.
I guess (my hypothesis) is basically that growth hormones are produced at night. You do most of your growing at night, but some of the affects (like muscle building) still affect you the day(s) after. So I guess you do grow at night mostly, but some of the affects carry on throughout the day.
