Causes of fatigue after sleeping too long
Sleep is a very important activity to help you create and collect memory, maintain the body's immune system, and make you energize while awake. At weekends, most of you will definitely plan to sleep longer to 'redeem' fatigue.
According to Michael Breus, sleep health expert, the need for human sleep is 7.5 hours a day. When you sleep, you will go through five stages with stages 1-4 with REM sleep periods (rapid eye movement) between each stage and each stage has a duration of 90 minutes. Sleeping too long which causes you to feel tired, associated with the stages of sleep.
Stage one or commonly referred to as light sleep. At this stage you swing from sleep and wake up so that it is easily awakened. At this stage your eyes move very slowly and your muscles begin to relax.
Many people experience sudden muscle contractions, called hypnic myoclonia, which is felt like a sensation of falling. If you wake up from one sleep stage, you may remember a fragmented visual image.
In the second stage, you will start sleeping. The average adult spends his night sleeping at this stage. In this second stage, breathing and heart rate start to be regular, eye movements stop, body temperature decreases, and goes into sleep. Brain waves also slow down.
What will happen at the third, fourth and fifth stages of sleep?
Stage three to four or commonly referred to as deep sleep, is a restorative stage of sleep in which energy is restored and also tissues and cells are repaired and grown.
At this stage of sleep your blood pressure drops, breathing slows, and the eyes stop moving and the muscles relax. In stage three, the brain waves become very slow, also called delta waves. In stage four, your brain only produces delta waves.
In stage five or often referred to as REM stage, the first 70-90 minutes will occur after you fall asleep, and repeat 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 happens, it is very likely that you will be awakened between stages two, three, four or when you are in the REM stage.
Waking up when you are in a deeper stage of sleep or even REM stages does not make your body feel better, but instead you feel your body tired. How, do you want to wake up now or sleep longer?
