Why Does It Feel Like Yesterday When You Sleep and Wake Up for the Second Time During the Day?

In fact, it is much more enjoyable than 6-7 hours of sleep, and when we wake up, we usually wake up. We feel as if we have slept for hours. However, despite all these positive aspects, we face a problem that most of us are familiar with.

When we sleep and wake up for the second time during the day, Why do we feel as if we lived yesterday before sleep?

First of all, we go through 4 to 5 cycles during sleep.

Besides these cycles, these stages of sleep It is divided into rapid eye movement (REM) and non-REM sleep. These 2 stages are quite important compared to the others because what happens during REM is significantly different from what happens during non-REM stages.

The first three stages of sleep consist of non-REM activities. The first stage is quite short and consists of the act of falling asleep and falling asleep. Then, as we get used to sleep our body and mind slow down. It is quite easy to wake up during this time.

In deep sleep, the body is in recovery mode and brain activity slows down.

Each sleep cycle lasts 70 to 120 minutes, and the early sleep cycles of the night are longer than REM. REM sleep is usually in the second half of the night takes place.

It is very effective in terms of sleep, brain and memory. Plays an important role in memory processing and helps the information we learn while awake to become more permanent in the brain. This process mostly occurs during REM.

In fact, when we sleep and wake up for the second time during the day, this is where we perceive the part before sleep as if it happened yesterday.

When we fall asleep for the second time during the day, the brain restarts the memory processing process. In this case, the events experienced in the previous waking period Even if it’s just for a short while, it feels like it happened yesterday. may cause.

Because the brain works to make the events experienced during the day more permanent. It reworks everything that happened. Sleep also has some effects on time perception. When we wake up, we often have little idea how long we slept.

Additionally, the reason for this misconception may be due to sleep inertia.

Sleep inertia, which occurs immediately after waking up from a short or long-term sleep; dizziness, drowsiness, disorientation, and altered perception of time It is a feeling of cognitive impairment that can cause

Sleep inertia usually lasts 15 to 60 minutes but disappears after waking up. It may continue for several hours. Experts attribute the cause of time confusion and sleep inertia after waking up largely to irregular sleep patterns.
