Sleep
Most teenagers need around eight to ten hours. Body clocks shift later during adolescence, so falling asleep early is genuinely harder — that is biology, not laziness. Light from screens delays sleep further, and a regular wake time steadies the whole system faster than a regular bedtime.

Movement
Roughly an hour a day of moderate activity, spread out, plus something that loads muscle and bone a few times a week. Walking, dancing, cycling and climbing stairs all count. Consistency beats intensity at this age.

Food
A balanced plate has starchy carbohydrates, protein, plenty of fruit and vegetables, some dairy or alternatives, and small amounts of oils. No single food is forbidden. Skipping meals to control weight usually backfires, and any worry about eating is worth raising with an adult early.

Worked example
Worked example: adjusting one thing
Someone falling asleep at 1 a.m. and waking exhausted does not need a whole new routine. Change one thing: a fixed wake time, with light and breakfast soon after. Within a week or two the sleepy point moves earlier by itself. One sustainable change beats five that last three days.
