How much deep sleep do you need every night

The average person spends around a third of their life asleep. In this time, our bodies are able to replenish energy stores and make repairs, while our minds organise and store the memories of the day before. The amount of sleep you need depends on your age, sex, health and other elements, and sleep cycles change as we grow older. This is divided into three stages, with each becoming progressively deeper. NREM3 becomes deeper, and if woken up, we can feel disorientated. Following on from this is rapid eye movement sleep REM , the stage at which we dream.

What Is Deep Sleep & How to Get More of It

Waking up tired, angry, or cranky? By tapping into your nighttime heart rate and movement patterns, these devices will be able to estimate how much time you spend in light, deep, and rapid eye movement REM sleep. Pretty cool, right? Each of these stages—or sleep types—serve a different purpose, so understanding how much of each stage you log can help you identify and address sleep-related issues.

Below, a breakdown of what you need to know about each sleep stage. Sleep researchers divide sleep into five stages—stages 1, 2, 3, and REM—but to keep things simple, Fitbit groups like sleep stages together. In the app, your sleep will fall into three stages: light, deep, and REM. That said, stage 2 sleep is not shallow, nor is it less important than other sleep stages. Stage 3: During deep sleep, you become less responsive to outside stimuli.

Breathing slows and muscles relax; heart rate usually becomes more regular. Your muscles are very relaxed. Your body is doing a lot of rebuilding and repairing. According to Siebern, deep sleep has also been shown to help strengthen your immune system.

REM is when most dreaming happens and your eyes move rapidly in different directions hence the name. Heart rate increases and your breathing becomes more irregular. In fact, it cycles through all of these stages multiple times a night. After this, during the second half of the night, the cycles mostly break down as your body alternates between light sleep and REM for the rest of the night.

On average, light sleep will take up about 50 to 60 percent or more of your night. Deep sleep, on th e other hand is likely to take up 10 to 25 percent depending on your age of your sleep. Too little, on the other hand, and sleep becomes unrefreshing. Lastly, REM makes up about 20 to 25 percent of your nightly sleep and mostly takes place in the second half o f the night.

Many medications can also block REM. Consistently getting too much REM could also create problems. When analyzing your sleep-stage data, keep in mind that the percentages above are based on broad averages. Even then, though, both Grandner and Siebern urge you to note that every individual has different sleep needs. There really is no ideal. Ask yourself, suggests Siebern, how you feel. Use that as your baseline by which to compare future sleep sessions.

Senior health and fitness editor Danielle Kosecki is an award-winning journalist who has covered health and fitness for more than 10 years. I worn my Fitbit for almost 1 year now and I really like it a lot. On the sleep stages some nights it gives me the pattern above so I can compare myself to others my age. Most of the time it shows me the old sleep pattern why is that? How can I fix it?

I like the new comparison chart better. I have a Fitbit ulta 2. Thank you. More than people think. Reading an amazing book called why we sleep by Matthew walker. Recommend it…. Same with me. I do, and I just found this info on mine. I can click on the sleep data for last night, for example, and see the cool graph breaking down REM from deep sleep, etc. When using your phone and you have the Fitbit app open, click on the sleep tile.

Touch that. Thank you, Maggie! I too, was looking all over for the benchmark on my computer. I was ready to give up until I saw your post. I have been having sleep apnea for over a year now and have seen several doctors, which greatly helped in my recovery process. Somehow it all makes sense now! I have a fitbit Flex 2, which is a new recently released device, and your not going to support it with updated features? Am I missing something??? So, I had the sleep stages show up for ONE night and then … no more.

What gives? A response from those in the know would be very welcome. Thanks, Elle. Make sure the sleep insight button is on. When you get the ap go to the sleep tab and it will show the sleep insight tab and it will tell you it has to be turned all the time for this function to work. Make sure the sleep insight button is turned on.

You have to leave it on all the time for it to work. You will find it under the sleep tab in fit bit functions. I am doing everything the article says but the sleep stages only appeared once. Is there a different model that actually works and does what it says it should do? HOw come no one can answer your questions??? I am looking forward for the answer about release date.

I am the one has problem with sleep and would love to know whats going on while I sleep. Please answer to their questions with date. The sleep tracker is very wrong. Last night, I awoke around 4 and was unable to go back to sleep until after 6 and even then my sleep was light.

When will sleep stages be coming for Charge 2? I bought one last night, after reading articles online that I understood as saying it was a currently available feature. I have a charge 2 and the sleep stages are not being recorded. March 27th is several weeks past, am I being too impatient in expecting to see these yet?

Why not let me try out this new feature to see if it works well? It would encourage me to buy more Fitbits instead of switching brands. When is this feature being released?

Thinking about LG smartwatch or Fitbit Charge 2 because of this feature. If it not coming out soon. It might just help me make my decision to go with the smartwatch! I had the stages on my blaze for three days and now it reverted back to the old way of showing it. How can I get back to see the stages again? Any reason why? I thought I was the only one. Actually wondered if I had imagined it.

I see sleep stages show up in the sleep mode on the app but it says no data available. If we have to wait more to see it functioning properly just say so. If it is coming in March there is precious little time to complete it. Not working at Fitbit. I have s Charge 2. The new sleep data format showed up on my dashboard for three days this week, then disappeared. I would love to get it back?

So when is someone going to answer the question of when sleep stages are coming back? I have a Charge 2. I really liked this new feature but only had it for a couple days and now it is gone. I would like to know how to get it back please. I absolutely love this new update … really accurate and love how it shows different stages of sleep!!

Well done Fitbit!!

How Much Deep Sleep Do You Need?

Slow wave sleep, also called deep sleep, is an important stage in the sleep cycle that enables proper brain function and memory. While most adults are aware that they should aim for between 7 and 9 hours of sleep each night, the science of sleep is quite complex. The two main categories of sleep are called rapid eye movement REM sleep and non-REM sleep, and each has important stages. There may be some ways to get both better sleep and more deep sleep each night, allowing a person to wake up feeling more rested and refreshed. The first stage of the sleep cycle is a transition period during which the body and brain shift from a state of wakefulness to one of sleep.

Deep sleep is the sleep stage that is associated with the slowest brain waves during sleep. Because the EEG activity is synchronized, this period of sleep is known as slow-wave sleep: it produces slow waves with a relatively high amplitude and a frequency of less than 1 Hz. The initial section of the wave is indicated by a down state; an inhibition period whereby the neurons in the neocortex are silent. The next section of the wave is indicated by an upstate; an excitation period whereby the neurons fire briefly at a rapid rate.

How much sleep do we need and why is sleep important? In adults, about three-fifths of a night's sleep is light non-REM sleep, one-fifth is deep non-REM.
