How Much Sleep Do You Need?
The amount of sleep required varies significantly across different age groups. During the early stages of life, an infant’s need for sleep is notably high, with recommendations indicating that they may require up to 17 hours of sleep each day.
As children grow and develop, the required sleep duration gradually decreases. For toddlers and preschoolers, the recommended range is typically around 10 to 14 hours per night. As individuals transition into adolescence, the need for sleep stabilizes at around 8 to 10 hours per night.
By the time adulthood is reached, the recommended duration decreases further, with most adults advised to aim for approximately 7 to 9 hours of sleep each night. It’s important to recognize these variations and prioritize age-appropriate sleep patterns to support overall health and well-being.
Babies, young children, and adolescents need more sleep than adults do. However, the exact amount of sleep depends on people’s overall health. Here is the table listed for the recommended daily sleep by different age range:
AGE RANGE | DAILY SLEEP (HOURS) | |
NEWBORN | < 3 months | 14-17 |
INFANT | 4-11 months | 12-15 |
TODDLER | 1-2 years | 11-14 |
PRESCHOOL | 3-5 years | 10-13 |
SCHOOL AGE | 6-13 years | 9-11 |
TEENAGER | 14-17 years | 8-10 |

What Are the Stages of Sleep?
Your brain and body will go through a different cycle of sleep when you fall asleep, and each cycle includes five distinct stages. Stages 1 through 3 are non-rapid eye movement sleep stages. In the non-REM sleep phase, the brain solidifies recently acquired memories and skills. Please refer to the source for a more enduring format. After NREM sleep our bodies go into REM cycle.
- First Stage: this is the first stage of sleep between being awake and falling asleep
- Second Stage: you become unaware of the surrounding environment, and your body temperature will drop gradually
- Third & Fourth Stage: you will reach deep sleep at this stage, and your breathing and heart rate will reach their lowest levels
- REM (rapid eye movement) sleep: as the final stage of your sleep cycle, your brain becomes most active and dream occurs. It will boost both your physical and mental performance when you wake up
On average, it takes you roughly 90 minutes to go through each cycle. See more details about different stages of sleep from our previous article How to understand Stages of Sleep And Sleep Better?.
Tips for Better Sleep
To improve your sleep hygiene, you’d better revamp your habits and routines every day. Here are some ways to improve your sleep quality:
- Do exercise every day: exercising will improve your sleep quality and reduce insomnia
- Avoid caffeine at night: avoid these stimulants before bed which can potentially interfere with sleep
- Turn off electronic devices before bed: your phone or tablet will emit blue light which can suppress the hormone necessary for the sleep
- Drown out sound and light: using earplugs or a white noise machine to reduce disruptions before bed
- Be consistent: going to bed and waking up at the same times every day helps your body develops a rhythm
- Use a sleep app: such as ShutEye. Choose relaxing sounds to fall asleep faster and track your sleep quality for better health.
Having a consistent schedule with enough time for sleep is vital to enhance your sleep hygiene, while the sleep time calculator can help you establish a bedtime and wake-up time. Finding the right recipe for sleep hygiene would involve certain trial-and-error, however, it would help to determine what works for you exactly.
