The 90 Minute Dream Cycle

One dream cycle is usually 90 minutes, where delta waves slowly increase frequency to morph into theta waves, which is the REM state of dreams. The awakening cycle in the morning, when the transition takes place from theta to alpha and finally beta (when we hit the snooze button!)

This precious morning time can be made highly productive as it is ripe with new ideas and insights related to the events of the day before and the forthcoming day.

MORE IDEAS FROM THE ARTICLE

Many people in the ‘theta’ state happen to get good ideas, as do people who are mentally relaxed due to being in the alpha state.

The repetitive task becomes automatic and disengages itself from the mind, leading to a free flow of ideas.

Our Brainwaves

The human brain is a highly complex electrochemical organ, generating as much as 10 watts of electricity.

This electrical activity is displayed in the form of four types of brainwaves: Beta, Alpha, Theta and Delta which correspond with focus, rest, creativity and deep sleep.

  • Beta waves (15 to 40 cycles per second) are generated during a highly engaged or aroused state of mind, like talking, debating or making a speech.
  • Alpha waves (a frequency of 9 to 14 cycles per second) are slower, with the brain in rest mode, happening when a person is reflecting, sitting down and resting, or walking in the park.
  • The Theta waves are generated during an even slower state of mind (5 to 8 cycles per second) usually when a person is daydreaming or is on a long freeway drive.
  • Delta waves (1.5 to 4 cycles per second) are the slowest, happening when we are in deep sleep.

RELATED IDEAS

Recent studies suggest we employ the same neurophysiological mechanisms while dreaming that we use to construct and recall memories while we are awake.

Studies also found that vivid, bizarre and emotionally intense dreams are linked to parts of the amygdala and hippocampus. The amygdala plays a key role in processing and memory of emotional reactions. The hippocampus is implicated in important memory functions, such as the consolidation of information from short-term to long-term memory.

About Consciousness

Consciousness is everything you experience - taste, pain, love, feeling. Where these experiences come from is a mystery.

Many modern analytic philosophers of mind either deny the existence of consciousness, or they argue that they can never be meaningfully studied by science.

What Is Consciousness?

  • The power of breathing is evident with people who have breathing disorders. As emotions affect our well-being, so does our breathing.
  • Our parasympathetic and sympathetic nervous systems are in control of producing feelings of calmness and the latter, the body's rapid involuntary response to stressful situations.
  • Many studies have confirmed the effects of breathing techniques against anxiety, stress, and insomnia. Although they do not disappear entirely, it helps alleviate their symptoms.
