The human body can perform it’s best at sea level. From the major organs(Heart, Liver, Lungs, Brain) to micro organs(Enzymes, Bacteria) all are accustomed with the weather of sea level. But the work-flow of organs vary from sea-level human to high-altitude human.
Then what is the High Altitude?
Earth’s surface that are high above mean sea level are referred to as high altitude. It is sometimes defined to begin at 2,400 metres (8,000 ft) above sea level. As we go higher, atmospheric pressure decreases exponentially with altitude and the concentration O2 decreases exponentially with altitude as well. And that causes various kind of mountain sickness.
- High altitude = 1,500–3,500 metres (4,900–11,500 ft)
- Very high altitude = 3,500–5,500 metres (11,500–18,000 ft)
- Extreme altitude = above 5,500 metres (18,000 ft)
So what you shouldn’t do at High Altitudes!
- As you reach higher, the concentration O2 decreases exponentially with altitudes. So never ever be excited or exert at high altitude. Because your body will demand more oxygen to stabilise it’s natural work-flow.
- Never drink or smoke at high altitude. If you drink or smoke, the alcohol and nicotine interfere with haemoglobin and as a result they dehydrate your body. Though higher altitudes have less oxygen in the air to begin with, you get even less oxygen to your brain. As result, you will face dizziness, fatigue, drowsiness, weakness and nausea.
- When you are in High Altitudes, try not to eat Fat Food, always eat light Carbohydrate Food. Because Fat needs more oxygen to burn than Carbohydrate.
- High Altitudes mean more exposure to sun and lesser exposure to thick atmospheric layer. More exposure means more sun burn, more UV expose and more expose to outer space radiation. So always full covered yourself at higher altitudes.
- Don’t come at High Altitudes without protecting your eyes. Always use eye goggle at High Altitudes.
