Complex cycles and systems operate in the brain. The Glymphatic (or Glial Lymphatic) system, discovered recently, takes care of the brain waste much like a complex sewer system.
The system is only active when one is asleep, and it clears our brain of all neurotoxic substances that have collected during the day.
It affects our learning, metabolism, hypertension, insulin sensitivity, and of course, mood.
Not getting enough sleep used to be something to boast of, but is now a sign of self-neglect and upcoming health issues.

As you climb, less oxygen in your blood means less oxygen in your brain.
At 15,000 feet, your cognitive performance, mood, and central nervous system functioning start to lessen. In severe cases, being at high altitude for long periods or without first acclimatizing, you are at a higher risk for swelling of the brain, (high-altitude cerebral edema - HACE.)
If you ascend without proper acclimatization, at around 9,000 feet, your lungs may begin to swell because the blood vessels constrict. Symptoms include a persistent cough and labored breathing.
If the swelling in your lungs worsens, high-altitude pulmonary edema (HAPE) can occur. Symptoms are a bluish discoloration of the skin, rapid breathing, and fever. The most effective treatment is to descend immediately.

Thomas Edison said that sleep is "a bad habit." Like Edison, we seem to think of sleep as an adversary and try to fight it at every turn. The average American sleeps less than the recommended seven hours per night, mostly due to electric lights, television, computers, and smartphones.
However, we are ignoring the intricate journey we're designed to take when we sleep.
When we fall asleep, the nearly 86 billion neurons in our brain starts to fire evenly and rhythmically. Our sensory receptors become muffled at the same time.
The first stage of shallow sleep lasts for about 5 minutes.

People used to speak of being left or right-brain dominant (where the left brain is more logical and algorithmic, and the right brain more artistic and intuitive).
However, both hemispheres of your brain are involved in all of the complex work you do. The most effective thinkers are the ones who learn to rely on both their intuitive judgments as well as their reasoning.
The theory goes that emotions reflect a more primitive form of thinking and that good thinking is only logical.
However, when faced with risky decisions, it is possible to talk yourself into almost anything. But, even a little anxiety in that situation can provide information too valuable to ignore.
