Dreamless Sleep or Quiescent Sleep.

   


Do you know that some people do not dream when they sleep? 


Yes and it is called "quiescent sleep". 


  Dreamless sleep is commonly referred to as "non-REM sleep" or "NREM sleep." This phase of sleep is characterized by the absence or minimal occurrence of dreams, in contrast to REM (Rapid Eye Movement) sleep, during which vivid and memorable dreaming often takes place. NREM sleep consists of several stages, including Stage 1, Stage 2, and Stage 3, with the latter being the deepest and least likely to involve dreaming.






1. NREM Stage 1: This is the transition stage from wakefulness to deeper sleep. It is a light sleep stage where you can be easily awakened. It's often brief and may involve fleeting, nonspecific thoughts or images, but it's not characterized by intense dreaming.


2. NREM Stage 2: This is a deeper stage of sleep where the body's processes continue to slow down. It is still relatively dreamless, although very basic and fragmented dreams may occur during this stage.


3. NREM Stage 3 (also known as NREM Stage 3 or slow-wave sleep): This is the deepest stage of non-REM sleep. It is characterized by slow brain waves and is the most restorative phase of sleep. It is very unlikely for dreams to occur during this stage.


  Dreams that are particularly vivid and memorable tend to occur during REM sleep, which is a separate phase of sleep characterized by rapid eye movements, increased brain activity, and where most dreaming occurs. Dreamless sleep, or NREM sleep, is essential for physical and mental restoration, memory consolidation, and overall sleep quality. Both REM and NREM sleep stages are important for a healthy sleep cycle.

Recent coups across Africa

  In recent years, Africa has witnessed several notable coups that have had significant political implications for the respective countries. Here are some examples: 1. Mali (2020): On August 18, 2020, the military in Mali staged a coup, ousting President Ibrahim Boubacar Keïta. The coup was led by military officers who formed the National Committee for the Salvation of the People. This followed months of protests against government corruption, economic instability, and security concerns. 2. Sudan (2019): In April 2019, Sudan experienced a coup that led to the removal of President Omar al-Bashir after nearly three decades in power. The military took control of the government following sustained mass protests demanding political change and better governance. 3. Zimbabwe (2017): In November 2017, the Zimbabwean military launched a non-violent "intervention" that resulted in the resignation of President Robert Mugabe. This intervention was triggered by internal power struggles ...

Let's talk about teeth misalignment

Image
  Teeth misalignment, also known as malocclusion, occurs when the teeth do not align properly. This condition can affect both the appearance and functionality of the teeth and jaw. There are several types of malocclusion, each with its own characteristics: 1. **Overcrowding**: Lack of space in the jaw causes teeth to bunch up or overlap, making it difficult to clean them properly. 2. **Underbite**: Lower front teeth protrude farther than the upper front teeth, causing the lower jaw to jut out. 3. **Overbite**: Upper front teeth overlap significantly over the lower front teeth. 4. **Crossbite**: Some of the upper teeth bite inside the lower teeth, causing an incorrect bite pattern. 5. **Open Bite**: When certain teeth do not meet when the mouth is closed, leaving a visible space. 6. **Spacing**: Gaps or spaces between teeth can occur due to missing teeth or abnormal growth of the jaw. Treatment for teeth misalignment may involve: - **Orthodontic Braces**: Traditional braces use wire...

Why do mosquitoes target the ear?

Image
  Mosquitoes don't specifically target the ear, but they are attracted to various factors that can lead them to bite anywhere on the body, including the ears. Mosquitoes are primarily attracted to carbon dioxide, body heat, body odor, and moisture. The ear area can be a warm and moist part of the body, making it a potential landing spot for mosquitoes.  Additionally, the carbon dioxide we exhale and the scents our bodies produce can attract mosquitoes to different areas, including the ears. It might seem like they are specifically targeting the ear, but it's more about the combination of factors that make certain body parts more appealing to mosquitoes at any given time. Do you know that the female and male mosquitoes live a completely different lifestyle?
