What time should a 14 year old go to bed?

Last reviewed: 14 September 2026

Fourteen is peak growth for a lot of teenagers and the point at which the body clock has finished moving. Both raise the amount of sleep needed, just as the schedule starts allowing less of it.

Bedtime chart for a 14-year-old

Find the time your teenager has to be up, and read across. These bedtimes are lights out, not the start of the evening — they already include about 15 minutes to fall asleep, which is a typical figure at this age.

If your 14-year-old wakes on their own at roughly the right time and is cheerful for the first twenty minutes of the day, the bedtime you are using is working. If they need waking every morning, it is too late — whatever the chart says.

How much sleep does a 14-year-old need?

A 14-year-old needs 8 to 10 hours of sleep a night. The major guidelines agree closely, and all of them give a range rather than a number because healthy teenagers genuinely vary by an hour or more either side.

Growth is not a metaphor here

Fourteen sits at or near the peak growth spurt for many teenagers — typically around 11 to 13 for girls and 13 to 15 for boys. Growth hormone is released in its largest pulses during deep slow-wave sleep, which is concentrated in the first two cycles of the night. That makes a consistently late bedtime more costly at this age than at almost any other, because it is the front of the night that gets shortened when bedtime slips.

The same is true of sport. Fourteen is when training loads step up and matches get competitive, and recovery from hard exercise raises sleep need rather than leaving it unchanged. A 14-year-old training four times a week on eight hours a night is under-recovered, and it shows up as injury and irritability before it shows up as slower times.

The body clock has finished moving

By fourteen the pubertal shift in melatonin timing is largely complete: the signal to sleep now arrives one to two hours later than it did at eleven. This is physiological and involuntary, and it is why simply setting an earlier bedtime so often fails — it produces a teenager lying awake in the dark, which over time teaches them that bed is where they do not sleep.

What actually moves the clock earlier is the morning, not the evening: fifteen to thirty minutes of daylight within an hour of waking, and a wake-up time held within about an hour seven days a week. Walking part of the way to school beats any wind-down routine you can construct.

Where the hours actually go

It is worth measuring rather than assuming. For one week, note the time the light actually goes off, not the time you said goodnight. Most parents of 14-year-olds find a gap of 45 to 90 minutes they did not know about — usually a phone, occasionally a console, almost never homework.

Signs a 14-year-old is not getting enough sleep

Tiredness at this age rarely announces itself as tiredness. It shows up as mood, motivation and concentration, and the pattern across the week is the giveaway — worse by Thursday, better after a weekend.

• sleeping four or more hours later at weekends than on school days
• falling asleep in lessons, or on the bus home
• a marked drop in mood or motivation during term time that lifts in the holidays
• daily reliance on caffeine, energy drinks in particular
• picking up minor training injuries more often than usual

Snoring every night, long pauses in breathing, or persistent mouth-breathing during sleep are different — those are worth raising with your GP rather than treating as a bedtime problem.

Evening habits that work at fourteen

Routines in the childhood sense are gone by fourteen. What replaces them is a small set of household norms that apply to everyone: phones charge outside bedrooms overnight, homework finishes an hour before lights out, the lights go down after nine, and the wake-up time does not move much at weekends.

Setting the phone rule as a whole-house rule rather than a restriction on them is what makes it survivable. At fourteen a rule that applies only to the teenager reads as a withdrawal of trust; one that applies to the adults too reads as how this family works.

How to move bedtime earlier without a fight

1. Fix the wake-up time first. Same time every day, weekends included, for a week. A stable morning anchors the body clock far more effectively than a stable bedtime does.
2. Move in 15-minute steps. Shift lights out 15 minutes earlier every three or four nights. The body clock will follow that; it will fight an hour.
3. Get daylight into the morning. Curtains open on waking, and ten to fifteen minutes outside before school if you can manage it.
4. End screens before the wind-down starts, not as part of it — stopping something engaging is itself stimulating.
5. Give it a fortnight. Two or three nights tells you nothing. Judge it by how the mornings look after two weeks.
