Metabolism During Sleep Cycles May Link to Obesity Risk

Metabolism During Sleep Cycles May Link to Obesity Risk

Do you ever wonder why you feel so tired after a full night’s sleep? It turns out that your metabolism during sleep may be to blame. According to a recent study, how your body handles energy during different sleep cycles may be linked to your risk of obesity. Keep reading to learn more about the study’s findings and how they could impact your health.


It’s an undeniable fact that we need sleep. Sleep, like food and water, is essential for life. But did you know that our brain still works while asleep? It is during these periods of restful unconsciousness in which many mental processes take place to help us function better both physically and mentally throughout the day.


The circadian clock in your brain tells you when to go to sleep. There are actually several clocks found throughout the body, and they all have their own cues for whether it’s time to hit those sheets! Some people might stay up later if their lights are bright enough. While others need complete darkness before falling asleep so as not to wake themselves up with insomnia medication.

During sleep, our body experiences several phases. The first is REM, and this means that one’s eyes dart back and forth with no rest in between cycles that is a rapid eye movement. The REM takes place for a certain number of minutes in a sleep cycle. It’s not uncommon to wake up briefly during these times because it can take a while before you felt asleep again after waking from an awake episode or dream state. However, during the rest time in the same sleep cycle, NREM (non-rapid eye movement) deep relaxation is experienced. Where they feel very lightheaded with closed eyelids throughout the entire night cycle time each night.

NREM sleep

You are in a light sleep state, where your breathing slows down and so do the activities of other organs. Brain activity also becomes less active while you’re sleeping. This makes it easier for your body’s systems to repair themselves after being awake all day long.

In a deep sleep stage, the body rests and processes events from earlier in the day. You usually experience this as soon after light sleeping, but before REM (rapid-eye movement) episodes take place. If you don’t get enough hours of restful slumber each night, then it’s likely that you experience fatigue ness during morning work or school even after spending enough time for sleep.

REM sleep

This is the phase of sleep where dreams occur, REM happens later at night and into the early morning. Memory processing occurs during this time as well. Therefore, people who wake up from their nightmares often have fresh memories about the event itself, even if they cannot remember anything else after waking up.

The brain activity rises along with faster breathing patterns in order for you not only to feel awake but also aware that what’s happening around you. While experiencing these terrifying visions or plots against oneself and yet somehow still calm enough inside.

Role Of Metabolism During Sleep

There are two types of sleep: NREM and REM. During the non-rapid eye movement (NREM) stage, the brain becomes less active while in deep slumber with muscular relaxation taking place. This is also known as Slow Wave Sleep because it’s characterized by low voltage waves similar to those seen when awake during a waking state. This causes the metabolism rate to slow down. 

On the other hand, rapid Eye Movement Periods result from our dreams being filled with vivid imagery which causes us loss for words. During this time the brain is also processing rapidly therefore the metabolism rate raises up significantly.

Relation Between Metabolism And Obesity

The three sources of energy that we have are protein, fat, and carbohydrates. When RQ numbers (the ratio between how much oxygen you breathe in versus carbon dioxide) equalize with each other then your body uses more carbs for its fuel instead of using fats or proteins as a source to make glucose from which our cells use it during metabolism.

The method of identifying sleep time RQ measurements and metabolic flexibility and inflexibility can become the way to identify the risk of getting meting metabolic diseases that as obesity and diabetes. 

The detection of a person’s physiological processes may help determine their potential risk for obesity and take preventative measures.


When you don’t get enough sleep, your body’s natural growth hormone levels can drop. This results in elevated cortisol and increased hunger. This is not just about changes at the chemical level but lack of quality rest also impacts how efficiently we metabolize food. While affecting other important functions such as memory retention or cognitive performance.

The effect of sleep loss on our metabolism is still being studied, but there’s evidence that it can affect the way we process food in conjunction with other hormones. Sleep-deprived people have lower levels of ghrelin and higher leptin which means they’re hungry more often than not – perfect for that late-night snacking session.

One night of poor sleep might cause a person’s metabolism to favor storing fat over building muscle. Many studies have linked poor sleep whether from insomnia or working the night shift to weight gain and health conditions like type 2 diabetes as well. An effect that can’t be ignored by those looking to maintain their physical fitness level over time. In fact, one study found just 1 week without adequate rest could affect a person’s risk factors for heart disease.


With obesity rates in the U.S. skyrocketing, it’s important to understand what causes people to gain weight and how they can lose unwanted pounds. The information we have provided may help you learn more about your metabolism during different stages of sleep cycles. Which could provide insight into why some individuals are prone to obesity when others are not. We hope this information has helped you answer all of the questions you had about the relationship between metabolism and obesity. Contact us if you have any queries regarding the blog.
