As you may know, I am a freshman at Saint Catherine College studying to be a psychology major.  I basically chose the topic of my weekly posts on what I’m learning in my psychology class.  I will be blogging about The States of Consciousness this week.

First thing is first…. Consciousness is the mental awareness of sensations, perceptions, memories, and feeling.  Altered States of consciousness is the awareness that is different from normal consciousness.

Fun Fact:  Smoking marijuana doesn’t make you feel any type of way; it makes you hallucinate what you think your feeling.

—— Sleeping has a lot to do with consciousness! ———

Biological Rhythm– is the cycle of biological activity such as sleep, temperature, heart rate, blood pressure

1*) Annual cycles are basically yearly cycles.  Things like geese migrating, grizzly bears hibernating, and humans experience seasonal variations in things can be labeled as basic like sleeping, appetite, and mood.  Seasonal Affective Disorder also known as SAD is a mood disorder that people experience during dark winter months.  The less amount of sunlight that people are exposed to the more depressed they become.

2*) The 28-day cycle also known as the menstrual cycle that occurs only in females averages about 28 days.  It is commonly known that menstruating affects the mood, but research shows that this is not true.  We make menstruation ‘bitchy’ because mothers warn their daughter(s) which is basically giving them a reason to act in such a way.  Pointblank period is that we all as humans have random ‘bitchy’ times.

Circadian Rhythm– is the biological rhythm that cycle over twenty-four hours

3*) 24 hour cycles are things that happen on a day to day time frame.  The 24 hour cycle varies with sleep, body temperature, and growth. 

Light triggers the suprachiasmatic nucleus to decrease (morning) melatonin from the pineal gland to increase (evening) it at night

4*) your sleep occurs through a  90 minute cycle.

Sleep Deprivation is being deprived of desired or needed amounts of sleep. When you are deprived you tend to have these symptoms

  • Fatigue & subsequent death
  • Impaired Concentration
  • Emotional Irritability
  • Depressed Immune System
  • Greater Vulnerability
  • Loss of Attention
  • Loss of ability to perform complex mental task

Sleep deprivation psychosis is the major disruption of mental and emotional functioning brought about by sleep loss.  Sleep patterns are order and timing of daily waking and sleep periods.  Although there are only 24 hours in a day we have a 25 hour cycle.  Melatonin is a hormone that is released by the pineal gland and is only produced at night.

A question that is commonly ask is why sleep?  Although there is no sure answer here are a few possible:

1] it is believed that sleep protects us.  By sleeping in the darkness when predators loomed about kept our ancestors from being in danger.  2] When you are sleep your brain tissue is being repaired and restored.  It also resets chemicals and sorts out ‘workings’ of that day. 3] Sleep also helps you remember.  This is because when you sleep all of the fading memories that you have is being rebuilt and restored.  4] During your sleep, the pituary gland releases a growth hormone.  Older people release less hormones and sleep a lot less.

when your parents ask have you grown over night; you can now say yes and tell them how and why 🙂
