Does sleeping 8-9 hours and drinking cow milk improve your chances of growing taller if your a teen?

Assuming you are not malnourished, your height is genetically predetermined. It is not good to have a lack of sleep, but getting adequate sleep is not going to make you any taller. Be happy with your height. No matter how tall you are, that doesn’t determine the kind of person you are! Good luck.

At 13 your sleep requirement for best growth can vary from 8-12 hours, depending on various factors. Training for sports, homework and growth all add an extra need to get adequate sleep. Adequate sleep, exercise and good nutrition can help you reach your best height. Cheat on any of these and you may lose out.
