Why Sleeping Too Long Makes Us More Tired?


Everyone likes to sleep, right? There's nothing more perfect than creeping slowly into bed and sleeping to your heart's content after a hard day's work. Lack of sleep can cause various health problems or disorders. But what if the opposite happens, and you sleep too long? What will happen if you sleep longer than you should? The answer is that you will actually feel tired. Why? Check out the reviews.

Causes of feeling tired after sleeping too long

Sleep is a very important activity to help you create and collect memories, maintain your immune system, and keep you energized while awake. On weekends, most of you will definitely plan to sleep longer to 'reedem' tiredness.

According to sleep health expert Michael Breus, the human need for sleep is 7.5 hours a day. When you sleep, you will go through five stages with stages 1-4 with periods of REM (rapid eye movement) sleep between each stage and each stage being 90 minutes long. Sleeping too long, which causes you to feel tired, is related to the stages in sleep. 

Stage one or commonly referred to as light sleep. At this stage your eyes move very slowly and your muscles begin to relax. 

Many people experience sudden muscle contractions, called hypnic myoclonia, which feel like a sensation of falling. If you wake up from stage one, you may remember fragmented visuals.

In the second stage, you will begin to sleep. The average adult spends a night's sleep at this stage. In this second stage, breathing and heart rate begin to regulate, eye movements stop, body temperature decreases, and we enter sleep. Brain waves also become slower. 

What will happen in the third, fourth, and fifth stages of sleep?

Stages three to four or commonly referred to as deep sleep, are restorative stages of sleep in which energy is restored and tissues and cells are repaired and grown. 

In this stage of sleep your blood pressure drops, your breathing slows down, and your eyes stop moving and your muscles relax. In the stage three, the brain waves become very slow, also known as delta waves. In stage four, your brain only produces delta waves. 

In stage five or often referred to as the REM stage, will occur the first 70-90 minutes after you fall asleep, and repeats every 90 minutes at each stage. This is the period when you dream. 

When you intend to extend the hours of sleep to sleep longer, then you will repeat the sleep cycle to return to the first stage. If this is the case, it is very likely that you will wake up between stages two, three, four or when you are already in the REM stage. 

Waking up when you are in a deeper sleep stage or even the REM stage, it does not make your body feel better, but instead you feel your body tired. How about you, do you want to wake up now or sleep some more?
