One big question we keep asking is, for how long do you need to sleep? As well all know, sleep is the best form of resting. But, the activities of man have proven a strong barrier to it. Hence, we may have to wake up almost immediately we close our eyes to rest.
This is where our sleep cycle calculator comes in. It is a simple app that helps you regulate your sleep and wake up time. Before using the Sleep Calculator, keep in mind that, as an adult, you can sleep off in 15 minutes and should have five or six cycles of sleep (90 minutes per cycle).
What Is the Sleep Calculator?
The sleep schedule calculator basically helps you calculate when you should sleep. It also allows you to know your wake up time depending on when you sleep. It's important as it aids in having a complete sleep cycle for better health.
What time should you go to sleep?
Just like you have a different body clock (circadian rhythm), our sleep times differ. While some prefer sleeping early, others leave it late, way past Netflix time.
What time should you wake up?
We have a guideline below, which tells us how much sleep we need by age. As an adult, it would be best to wake up seven to nine hours from your sleeping time.
How Much Sleep Do You Need?
We know that sleep and lack of it affect our daily operations either positively or negatively from studies. Sleep helps the brain to process faster, while a lack of it hinders metabolism. The amount of sleep we need (not what we want) depends on our age.
Do your need for sleep change with age?
Yes. Research suggests that adults should sleep seven hours or more per night on a regular basis for optimal health. On the other hand, another study reports that a teenager should sleep 8 to 10 hours per 24 hours; children 6 to 12 years should sleep 9 to 12 hours; children 3 to 5 years should sleep 10 to 13 hours; children 1 to 2 years should sleep 11 to 14 hours; infants 4 to 12 months should sleep 12 to 16 hours. Additionally, according to the NSC, newborns should sleep 14 to 17 hours.
Here is a table that shows how much sleep you need according to your age:
|Age Group||Age Range||Recommended Hours of Sleep|
|Newborn||Birth to 3 months||14 to 17 hours|
|Infant||4 to 12 months||12 to 16 hours|
|Toddler||1 to 2 years||11 to 14 hours|
|Preschool||3 to 5 years||10 to 13 hours|
|School||6 to 12 years||9 to 12 hours|
|Adolescent||13 to 18 years||8 to 10 hours|
|Adult||18 to 65 years||7 to 9 hours|
|Older Adult||65 years and older||7 to 8 hours|
These stats clearly show that the sleep hour requirement decreases with age increase.
What is a regular sleep pattern?
It may sound alien, but everyone has a sleep pattern, from a toddler to a granny. The question now is, what is a general pattern for sleep? Normally from the above information, your hours of sleep decreases with age. Thus, an adult needs six to seven hours of sleep to function optimally.
This pattern shows that you should wake up after a number of hours no matter the tie you wander off to dreamland. While some of us are heavy sleepers, a good alarm clock can help with that.
What are the stages of sleep?
Once you shut your eyelids in slumber, your body undergoes sleep cycles. These cycles have phases that run till you wake up. We'll call these phases the stages of sleep. Here are four sleep stages, according to the American Academy of Sleep Medicine:
- N1 stage: You know that period just before you finally wander off? You can call it stage one – the point you fall asleep.
- N2 stage: Now you're off to wonderland, your systems are shutting down at this stage, and your temperature is reducing. Your heart rate is normal, and you are no longer conscious.
- N3 stage: This is the point of total shut down. Your heart rate is slow, and so is your blood pump. Funny enough, your eye moves back and forth under its lids. This is the deepest part of sleep and the highest point of relaxation.
- REM: The last stage of your sleep cycle - takes about 20-25% of the total sleep time. This is the point you enter into dreamland, and the brain is most active. It helps boost brain activity when you wake up.
