Why Trust Us?

Besides eating, drinking, and breathing, sleeping is the most essential function to the human body — mentally and physically. We can't function properly without sleep, but according to a new study in the Morbidity and Mortality Weekly Report by the Centers for Disease Control and Prevention (CDC), more than a third of American adults aren't getting enough sleep on a regular basis. But how much sleep is too much? How much sleep is too little? How much sleep do I need? All of these are good questions, and we're here to answer them for you.

In this guide, our sleep specialists from Mattress Land will help you solve "how much sleep I need", offer tips to improve your sleep, and recommend some quality mattresses that can boost your sleep health.

How Much Sleep Do I Need?

In general, the average adult needs seven to nine hours of sleep, according to the Centers for Disease Control and Prevention. 

You may be asking how researchers arrived at this figure. Well, sleep has been one of the most explored issues by scientists over the last century, so there's plenty of data to back up this statistic. When scientists studied the amount of sleep people require based on their age, they considered a few things. Typically, they examine the memory and cognitive abilities of those being studied, depending on how long they sleep.

Scientists also research the health of babies, toddlers, and children in relation to how well they grow for their age group. Researchers could estimate a suggested fixed number of hours of sleep for each age group based on the findings. How much sleep do adults require? What about the children? According to this sleep chart reviewed by Sleep Physician Dr. Abhinav Singh, here’s how many hours of sleep each person needs based on age.

How Much Deep Sleep Do You Need?

Now that we've addressed the question of "how much sleep do I require," how much of that sleep should be deep sleep? Before we get into how much of your sleep cycle should be deep sleep, let's first define it and why you need it.

What is Deep Sleep?

Deep sleep, also known as slow-wave sleep, occurs during the third stage of NREM sleep. Electrical activity in the brain shows in long, slow waves termed delta waves during deep sleep. You usually settle into a deep sleep within an hour after falling asleep and have increasingly shorter bouts of deep sleep as the night progresses. Automatic bodily processes like respiration and heart rate are also very slow during this period, and your muscles relax. It might be tough to wake you up, and coming up from a deep slumber can cause brain fog for up to an hour.

Why is Deep Sleep Important?

While all stages of sleep are required for optimal health, deep sleep has distinct physical and mental advantages. During the deep sleep stage, your body produces growth hormones and works to build and repair muscles, bones, and tissue, as well as maintain immune system function. Deep sleep is also necessary for cognitive function and memory, and it is considered to help with language acquisition, motor abilities, and brain development.

How Much Deep Sleep Do You Really Need?

The quantity of deep sleep a person requires is usually proportional to the amount of total sleep a person obtains. According to the Sleep Foundation, most individuals should sleep seven to nine hours every night, with 13 to 23 percent (approximately 55–97 minutes) spent in deep sleep.

4 Ways to Boost Your Sleep Quality

Insufficient sleep is a threat to public health on a national scale. Not getting enough sleep (or too much sleep) can lead to a variety of issues ranging from minor annoyances (daytime tiredness or irritability) to major health concerns (heart disease and stroke). So, making sure that getting the recommended amount of sleep is a top priority that can improve your health and boost your mood and energy.

Improving your sleep health is more than just changing your routine and habits — it's also about your environment and how that can also affect your sleep. Here are some examples of how you can boost your sleep health for a long, deep slumber.

1.     Be Consistent

Set a schedule, go to bed at the same time every night, and get up at the same time each morning, including on the weekends.

2.     Remove Gadgets

Before you go to sleep, take out all electronic devices like laptops, smartphones, TVs, or tablets from your bedroom.

3.     Get Some Exercise

If you can't sleep because you're wide awake at night, getting physically active during the day can help you burn some of that energy so you can fall asleep more easily at night.

4.     Find the Right Mattress

We recognize that not everyone understands how to answer "how much sleep do I need," and because sleep science is always releasing new findings, things may change. But you know that you may still have questions, so here are some of our clients' most often asked questions.

Q: How much sleep do teenagers need?

Although teens have a reputation for sleeping late and waking up even later, kids 13–18 years old need 8–10 hours of sleep per night. The reasons your teenagers are sleeping in late and waking up late is due to their biological clock resetting as well as the melatonin in their bodies being released later making it harder for them to fall asleep earlier.

Q: How much sleep should a 3-year-old get?

It is recommended that a 3-year-old needs at least 10–13 hours of sleep (including naps) to maintain good health.

Q: How much sleep should a 7-year-old get?

Even though there is no guaranteed rule, the general rule of thumb is that 7-year-olds need 10–11 hours of sleep per night.

Q: How much sleep should a 12-year-old get?

On the cusp of entering teenage hood, your pre-teen will need 9–11 hours of sleep a night as they start heading into growth spurt territory.
