Our Internal Biological Clock
- If we want to get more out of each day, we might need to consider synchronizing with our own internal body clock, working according to our peak periods of creativity, energy and activity.
- Our biological clock controls most of our body’s functions, like the circadian rhythms that manage the sleep and wake cycles.
- People working in shifts, for example, are thrown off their natural clocks, and experience fatigue, jet lag or sleep disturbances.

Our Natural Internal Thermostat
Our mental alertness, mood, stress, hunger levels, heart mechanism, and immunity are controlled by the various rhythms synced to the thermostat-like biological clock in our body.
Circadian rhythms control our eating habits, body temperature, digestion, hormone levels, resulting in a huge impact on our overall health. Any interruption in our circadian rhythm can lead to many health conditions known as lifestyle diseases.

The Best Time For Our Activities
- Sleeping: Our age determines our body’s sleep cycle, with teens leading more sleep than adults. Afternoon naps are great for your health.
- Eating: The time we eat might help us control our metabolism and prevent gastronomical problems, and altering your eating schedule resets your biological clock.
- Exercising: Regular exercise is a must, and physical strength is at its peak from 2:00 pm to 6:00 pm.
- Thinking: Our minds usually work best in the morning, making it the best time to tackle heavy activities. Concentration dips in the daytime when we feel sluggish, but new studies find that creativity is enhanced in a tired brain.

Changing Your Circadian Rhythm
One can establish a productive daily schedule by:
- Establishing a sleep schedule, where you wake up (and go to bed) at the same time, and do not hit the snooze button.
- Giving your new schedule some time to sink in, and not giving up.
- Paying attention to your energy levels, which are unique to you, and shifting your activities accordingly.
Our busy schedules often throw the natural cycles of our body off-track. If we go against nature, here are bound to be health implications. Some people perform better in the early hours of the day, while others are at their peak in the evening.

Aphantasia: Image Not Found
Aphantasia is a phenomenon in which an individual cannot conjure an image of a face or thing in their minds. There is no inner ‘mind’s eye’ in these people and the mental imagery i...
Discovery of Aphantasia
Aphantasia was first described in the early 1800s by Francis Galton in a paper on mental imagery. It was not until 2015 that the phenomenon was further studied and the term was coined.
One of the major studies was with a patient who had undergone a minor surgery in 2005 and later could no longer generate visual images within the ‘mind’s eye’. The details of the study were published in 2010, which led to many others coming up with similar symptoms.
Binocular Rivalry
This was a technique used by the researchers to help test the image forming inside the brain of the individuals.
The experiment led to the finding that a recent viewing of an image had no correlation with the imagining of the image.

The Beginnings of Psychology
Psychology was not separate from philosophy until the late 1800s.
- During the 17th century, philosopher Rene Descartes introduced the idea of dualism - that the mind and body were two entities that interact to complete the human experience.
- While early philosophers relied on methods such as observation and logic, today's psychologists use scientific methodologies to draw conclusions about human thought and behavior.
- Physiological research on the brain and behavior also contributes to psychology.
Psychology as a Separate Discipline
- During the mid-1800s, a German physiologist Wilhelm Wundt outlined many of the major connections between the science of physiology and the study of human thought and behavior.
- He viewed psychology as the study of human consciousness and tried to apply experimental methods to study internal mental processes.
- His processes are known as introspection and seen as unreliable and unscientific today, but it helped to set the stage for future experimental methods.
- The opening of his psychology lab In 1879 is considered to be the official start of psychology as a separate scientific discipline.

Repression as a defense mechanism
Repression can best be defined as the psychological defense mechanism that involves pushing undesired thoughts into the unconscious in order to not think about them anymore.
...Types of repression
Repression is of two types: primary and proper.
While the primary one takes into account the fact of hiding undesired thoughts or facts, the proper one takes place whenever an individual becomes aware of the thoughts that had initially been hidden and tries to hide them again.
Repression and its way of functioning
The objective of hiding our undesired thoughts in our unconsciousness is to feel less anxious.
However, Freud stated that this process can backfire at any point, as these hidden thoughts or feelings can still create anxiety, eventually leading to psychological distress.
