What Happens to Your Body When You Climb Everest
Climbing Everest
It’s almost impossible to imagine the immense physical and psychological challenge of climbing to the top of 29,029-foot Mount Everest.
Even at Base Camp, at 17,600 feet, there's about 50 pe...
Your brain while climbing Everest
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.)
Your lungs while climbing Everest
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.

How to Powerhouse through Sleep Deprivation

Get through sleep deprivation:
- Stabilize your blood sugar, by eating hearty food (protein and fat) more often.
- Reduce refined carbs and increase fats and proteins.
- B-complex vitamin supplements can give you an immediate boost in alertness and mental clarity.
- Soak in an Epsom salt bath - might even help you get enough energy to exercise the next day.
- Drink more water than you usually do to help compensate.
- Exercise is the single best way to “take out the trash” in your body, and after staying up more hours than you should.

This Neuroscientist Decoded the Brain Patterns of Meditators - Mindful
Mindfulness And Our Brains
Meditation or mindfulness is not a uniform, unchanging process, but a highly subjective one, having unique effects on different individuals.

Reading The Mind During Mindfulness Meditation
Extensive experimentation recording more than 2000 brain patterns per person led to certain insights which were not possible before.
- Meditators had the maximum amount of time paying attention to their breath.
- A feeling or even the warmth of the heart can be the center of focus during meditation, instead of repeating words or phrases, which are just instrumental for distracting us from our own thoughts.
- The moments of meditation are not static, but an ever-changing kaleidoscope of experiences, feelings and mind-states.
