1. Sleeping and fully functioning of the body

 

Many body processes take place in that time we are sleeping, like hormones secretion (a pituitary gland that secretes growth hormone which helps our body to grow), brain restoring the new information and getting rid of the toxic metabolic wastes, re-organization of the nerve cells. also, it is time for the body to repair cells, and restore energy.

You might wonder about the purpose of sleeping? after all why to do so? Some theories explain how sleeping is so important to the normal functioning of the body.

 Sleeping facilitates us to be emotionally healthy 

Many people falling asleep while being so tensed, so stressed, sorrowful, discouraged, feeling down, and sad when they wake up they are more relaxed, and they have refreshed emotions due because some physiological processes are happening while they were sleeping. 

 The limbic system is the system of the nervous system that regulates our emotions and is involved in memory its structure are the amygdala, hippocampus, hypothalamus, and thalamus.

Amygdala is located in both left and right temporal lobes and is mostly concerned about anxiety and fear (mood and anxiety disorders). the point here is that when you get enough sleep, the amygdala can respond more adaptively, but if you're sleep deprived this part is more likely to be overreactive.

 Sleeping and the normal functioning of the brain

By the theory of neuroplasticity, the brain has the ability to modify its connections or re-wire itself. it would be so devastating without such ability because the individual would not develop from infancy through adulthood or recover from the brain injury.

In having a deep sleep, the brain's cleaning system "glymphatic system " cleans the brain out of the metabolic waste materials, and when these wastes are not cleaned they accumulate in the brain leading to premature brain degeneration.

 Sleeping and the cellular restoration

By the restorative theory, it says that "the body needs to rest to restore" during the sleeping time, our cells can restore and also grow. Muscle cells are repaired, tissue growth takes place, and many other restorative processes take place.

 Sleep and body weight balance

There is hunger regulating hormones called ghrelin or lenomerelin produced in the gut and leptin produced by the fat cells. The ghrelin is transported through the bloodstream to the brain and it tells the brain to become hungry for seeking food, its function is to increase the appetite. the same way leptin is transported through the bloodstream and controls how much we eat.

It was discovered that due to sleep deprivation, ghrelin level is increased and leptin level is suppressed leading to the increased hunger and appetite in the individual and this can lead to weight gain.

 

 

2. What is happening when we are sleeping?

 

Throughout the night, our body cycles through two types of sleep in four stages, those two types are non-rapid eye movement (n-REM)and rapid-eye-movement (REM) also called paradoxical sleep the first three stages are involved in nonrapid eye movements while the last stage is in rapid eye movement. there are many series of actions that are happening through those four stages:

 

• Stage 1: This is considered as the transition between awakeness and falling asleep. alpha waves released by the encephalon are detected on the EEG (electroencephalogram) eye movements and heart rate are reduced on this stag 

• Stage 2: This is the stage where those alpha waves are replaced by the theta waves. this stage is associated with a decrease in the body temperature, relaxing of the heart and muscles and also the eye movements stop

• Stage 3: On this stage and the fourth one we experience a deep sleep and the individual hardly awakens. Muscle tonus, breathing rate together with the pulse decrease even further, and delta wave is marked on the EEG (electroencephalogram)

• Stage 4: This is the last stage of sleep (90 minutes after falling asleep) also known as quiet sleep, delta waves are detected on the EEG and there is rapid movement of the eyes from side to side. breathing rate and the muscular tonus also increase and this is the stage where we dream 

 

3. Abnormalities and diseases associated with sleep deprivation

 

Many lessons would make people sleep-deprived, maybe the lessons might be the living conditions of an individual, having no knowledge about how destructive is sleep deprivation, also it might be out of ignorance. Being sleep-deprived or having no sleep at all have associated health risks.

When you do not have enough time to sleep, it affects your heart, kidney, blood, and mental health. Some of the associated risks are listed below:

• Depression

• Anxiety

• Poor memory

• Insulin resistance

• Obesity/ weight gain

• High blood pressure

• Weakened immune resistance

• Inability to focus and retaining concentration

• Some of the chronic diseases like heart diseases and diabetes

 

Conclusion

 

It is important to have enough sleeping time no matter the condition or the situation you could be in, you have to try your best. 

As we have seen there are many diseases and other risks related to sleep deprivation, so it is worth having measures set to practice having enough sleeping time throughout the day for better health.

To conclude I would like to encourage you to do all it requires for having good health through this step of having enough sleeping time throughout your day and for more advice, if needed you might visit the doctor to assess the underlying cause of your worsening health condition
