It is the mind that forces sleep, making it compulsory and punishing its denial.
Sleep is not an absence of activity for the mind, or its host, the brain, but it is mostly a prioritization cycle for internal systems.
Normally, paying attention to anything is often the sole priority of the mind in a moment. There are situations where someone is somewhere but does not follow because they are lost in thoughts. This says that there is just one prioritized quantity in the mind, at any moment.
Prioritization for any quantity on the mind grants full access to locations for properties that include what is labeled as memory, feelings, emotions and reactions. It is this access that allows things to be known, understood and felt. Prioritized quantity can also acquire other properties like interest and curiosity, to deepen its engagement.
Other quantities on the mind in any instance are pre-prioritized. There are fast and numerous interchanges with prioritized, but just one is prioritized at any moment, conceptually.
Alternatively, trying to focus the eyes on two different things at the same time, but finding out that while the view takes in multiple streams, just one thing is on the mind per moment, though interchanges occur. Showing how the mind exceeds the senses.
Property acquisition by pre-prioritized quantities is regular, but they are incapable of driving high necessities to flee—when in danger, or to meet a need, like steep thirst or starvation.
All internal senses have versions, equivalents or representations on the mind, as properties. The incoming signals from them become mostly pre-prioritized to acquire those. They sometimes get priority, but less, because of how external sensory channels take precedence during the day.
All quantities in the mind, for all properties, must become prioritized, to degrees, per cycle. This means that the quantities for the properties of liver, pancreas, stomach, spleen, kidneys and so forth must be prioritized at least once, per given cycle. The cycle varies, but one general angle the mind uses is sleep, so that while exteroception dips, interoception gets its moment, including for property rearrangements.
The quantities are able to access different property locations, acquiring various properties, including for what—traditionally—should be for exteroception, like delight, sadness and so forth.
This process gives updates—as regulation or control, for limits or extents of how they should work. It also shapes preparedness, should there be a crisis.
The liver works, but cannot by itself know when something is wrong with it because it is the mind that has the information of its operational dimensions and would get if something went wrong, to give it priority, creating alert, sending help, or to make the individual seek help.
The drill for whatever the mind does, for internal senses, in emergencies is carried out during prioritization of their quantities.
In some latest research, there is some strong evidence that DSIP (Delta Sleep Inducing Peptide) can reduce sleep disturbance and waking by inducing a deeper sleep.
If sleep is denied and the cycle for some internal senses is missed, there is a general functional drag because if pre-prioritized quantities do not get prioritized within a cycle or two, they slow down, sending lethargy to internal senses and whatever stays prioritized takes more to get to locations.
It is the drag of quantities—as fatigue of internal senses—that shows up to know that sleeplessness is not great, making the mind counteract. This drag is a moment of vulnerability for some internal senses, where their lack of optimum function could result in inefficiency that may lead to some mild conditions or worse.
Though sleep is a property of the mind that has to be acquired, stimulants can drive the acquisition of liveliness as properties or energy. Prolonged sleeplessness makes functioning hard.
