How Much Sleep Do You Need by Age? Recommended Sleep Hours
Sleep is one of the most important parts of a healthy lifestyle, but many people do not know exactly how much sleep they need by age. Sleep requirements change throughout life. Babies and young children need considerably more sleep than adults, while teenagers also require more sleep than most adults.
Getting enough sleep regularly can support physical health, emotional well-being, concentration, memory, learning, and everyday energy. However, sleep needs are not exactly the same for everyone. Age, lifestyle, health, activity levels, and individual differences can all influence how much sleep a person needs.
So, how many hours of sleep do you need by age? This guide explains recommended sleep hours for newborns, infants, toddlers, children, teenagers, adults, and older adults.
How Much Sleep Do You Need by Age?
The amount of sleep recommended each day changes as we grow. According to the Centers for Disease Control and Prevention (CDC), newborns need the most sleep, while adults generally need at least seven hours per night.
Recommended Sleep Hours by Age
| Age Group | Age | Recommended Sleep |
|---|---|---|
| Newborns | 0–3 months | 14–17 hours |
| Infants | 4–12 months | 12–16 hours, including naps |
| Toddlers | 1–2 years | 11–14 hours, including naps |
| Preschoolers | 3–5 years | 10–13 hours, including naps |
| School-age children | 6–12 years | 9–12 hours |
| Teenagers | 13–17 years | 8–10 hours |
| Adults | 18–60 years | 7 or more hours |
| Adults | 61–64 years | 7–9 hours |
| Older adults | 65+ years | 7–8 hours |
These are general recommendations. Individual sleep needs can vary, and sleep quality is also important.
Why Is Sleep Important?
Sleep is not simply a period when the body shuts down. During sleep, the body and brain perform important processes that support overall health.
Good-quality sleep can help support:
- Memory and learning
- Concentration and attention
- Emotional well-being
- Physical recovery
- Immune function
- Normal daily energy
- Healthy brain function
- Overall quality of life
When you regularly get less sleep than your body needs, you may experience daytime tiredness, difficulty concentrating, mood changes, and reduced alertness.
For children and teenagers, getting enough sleep is particularly important because their bodies and brains are still developing.
How Much Sleep Do Newborns Need?
Newborn babies between 0 and 3 months generally need around 14–17 hours of sleep per 24 hours.
Newborns do not usually sleep for one long stretch at night. Instead, their sleep is spread across multiple periods throughout the day and night.
As babies grow, their sleep patterns gradually become more predictable.
Parents should remember that newborn sleep can vary considerably from baby to baby. If a baby has unusual sleep patterns, feeding difficulties, breathing problems during sleep, or other concerns, parents should speak with a pediatric healthcare professional.
How Much Sleep Do Infants Need?
Infants between 4 and 12 months generally need 12–16 hours of sleep per 24 hours, including naps.
At this stage, sleep plays an important role in growth and development. Babies may gradually develop longer periods of nighttime sleep, although waking during the night can still be normal.
A consistent bedtime routine can help establish healthy sleep habits.
Parents can create a calm sleep environment by keeping the room comfortable, following a regular routine, and reducing unnecessary stimulation around bedtime.
How Much Sleep Do Toddlers Need?
Toddlers between 1 and 2 years old generally need 11–14 hours of sleep per day, including naps.
Toddlers are becoming increasingly active and independent, so maintaining a consistent sleep schedule can sometimes be challenging.
A regular bedtime, calming activities before sleep, and a comfortable sleep environment can help toddlers develop healthy sleep habits.
How Much Sleep Do Preschoolers Need?
Children between 3 and 5 years generally need 10–13 hours of sleep per day, including naps.
Some preschool children continue taking daytime naps, while others gradually stop napping.
Signs that a preschooler may not be getting enough sleep can include daytime irritability, difficulty concentrating, excessive tiredness, or changes in behavior.
A predictable bedtime routine can make the transition to sleep easier.
How Much Sleep Do School-Age Children Need?
Children between 6 and 12 years generally need 9–12 hours of sleep per 24 hours.
School, homework, sports, entertainment, social activities, and electronic devices can all affect a child’s bedtime.
Adequate sleep is important for children’s attention, learning, behavior, and overall well-being.
Parents can encourage better sleep by maintaining a consistent bedtime and wake-up time, including on weekends when practical.
How Much Sleep Do Teenagers Need?
Teenagers between 13 and 18 years generally need 8–10 hours of sleep per 24 hours.
Teenagers often struggle to get enough sleep because of school schedules, homework, social activities, screen time, and changes in their biological sleep timing.
Not getting enough sleep regularly can affect daytime alertness, concentration, learning, mood, and overall health.
Parents and teenagers can work together to create a consistent sleep schedule and reduce unnecessary screen use close to bedtime.
How Much Sleep Do Adults Need?
Most adults aged 18–60 should get at least 7 hours of sleep each night on a regular basis.
Many adults function well within a range of approximately 7–9 hours, although individual needs vary.
Work schedules, stress, family responsibilities, travel, exercise, lifestyle habits, and health conditions can all affect sleep.
A busy schedule does not eliminate the body’s need for sleep. Regularly cutting sleep short can make it difficult to maintain energy and concentration during the day.
Is 6 Hours of Sleep Enough for Adults?
For most adults, regularly getting only 6 hours of sleep is below the recommended amount.
Some people may feel that they can function on six hours, but feeling accustomed to short sleep does not necessarily mean that the body is getting the amount of sleep it needs.
Adults should generally aim for at least 7 hours of sleep each night and pay attention to daytime alertness and overall well-being.
How Much Sleep Do Older Adults Need?
Adults aged 61–64 are generally recommended to get 7–9 hours of sleep, while adults aged 65 and older generally need 7–8 hours.
It is a common misconception that older adults need very little sleep. Although sleep patterns often change with age, the need for adequate sleep remains important.
Older adults may experience changes such as waking more frequently during the night, going to bed earlier, or waking earlier in the morning.
Persistent sleep problems should be discussed with a healthcare professional.
Does Sleep Quality Matter as Much as Sleep Quantity?
Yes. The number of hours you sleep is important, but sleep quality also matters.
For example, a person may spend eight hours in bed but wake repeatedly throughout the night. In that situation, the total time in bed may not accurately represent the quality of their sleep.
Healthy sleep generally involves sufficient duration, good continuity, and feeling reasonably refreshed during the day.
If you consistently wake up exhausted despite spending enough time in bed, it may be worth discussing the problem with a healthcare professional.
What Happens When You Don’t Get Enough Sleep?
Occasionally getting less sleep than usual can happen to anyone. However, regularly sleeping less than recommended may affect how you feel and function during the day.
Insufficient sleep may contribute to:
- Daytime sleepiness
- Reduced concentration
- Difficulty remembering information
- Irritability or mood changes
- Reduced alertness
- Lower productivity
- Increased risk of accidents
- Difficulty maintaining healthy daily routines
For children and teenagers, insufficient sleep has also been associated with problems involving attention, behavior, learning, and overall health.
The goal is not simply to sleep as long as possible. The goal is to get an appropriate amount of good-quality sleep consistently.
10 Simple Tips to Improve Your Sleep
If you are struggling to get enough sleep, small changes to your daily routine may help.
1. Follow a Consistent Sleep Schedule
Try to go to bed and wake up at approximately the same time every day.
A consistent schedule can help your body maintain a regular sleep-wake rhythm.
2. Create a Relaxing Bedtime Routine
Give yourself some time to wind down before going to bed.
Reading, taking a warm shower, listening to calming music, or practicing relaxation techniques may help you transition into sleep.
3. Reduce Screen Time Before Bed
Phones, tablets, computers, and televisions can keep your mind stimulated late at night.
Try reducing unnecessary screen use before bedtime and keep your bedroom focused on sleep.
4. Get Natural Light During the Day
Exposure to natural light, particularly earlier in the day, can support your body’s regular sleep-wake cycle.
Spending some time outdoors during the daytime can be a simple addition to a healthy daily routine.
5. Stay Physically Active
Regular physical activity can support overall health and healthy sleep habits.
However, if exercising close to bedtime makes it harder for you to sleep, consider moving your workout earlier in the day.
6. Avoid Too Much Caffeine Late in the Day
Coffee, tea, energy drinks, and other caffeinated products can interfere with sleep in some people.
If caffeine affects your sleep, consider limiting it later in the day.
7. Make Your Bedroom Comfortable
A quiet, dark, and comfortable bedroom can make it easier to sleep.
Consider your room temperature, lighting, mattress, pillow, and noise level.
8. Avoid Heavy Meals Close to Bedtime
Eating a very large meal shortly before going to bed may make some people uncomfortable.
Try to give yourself enough time between a heavy meal and bedtime.
9. Limit Long or Late Naps
Naps can be useful for some people, but long or late naps may make it harder to fall asleep at night.
If nighttime sleep is a problem, consider adjusting the timing and duration of daytime naps.
10. Pay Attention to Your Body
If you regularly feel sleepy during the day despite spending enough time in bed, your sleep quality may need attention.
Persistent problems should be discussed with a healthcare professional.
How Can You Tell If You’re Getting Enough Sleep?
There is no single number that works perfectly for every person.
Along with following age-based recommendations, consider how you feel during the day.
You may not be getting enough sleep if you frequently:
- Feel tired shortly after waking
- Struggle to stay awake during the day
- Need excessive caffeine to feel alert
- Have difficulty concentrating
- Feel unusually irritable
- Sleep much longer whenever you have the opportunity
- Frequently fall asleep unintentionally during the day
These signs do not automatically mean that you have a sleep disorder. However, persistent problems are worth discussing with a healthcare professional.
Can You Sleep Too Much?
More sleep is not automatically better.
Occasionally sleeping longer than usual can be normal, especially after illness, intense physical activity, travel, or a period of insufficient sleep.
However, consistently sleeping for unusually long periods while still feeling tired may deserve medical attention.
The appropriate amount of sleep depends on age, individual needs, health, and circumstances.
