3. Latest research on the impact of altitude on human body
A recent study published in the medical journal Plateau Medicine shows that there are significant differences in the impact of different altitudes on human health:
| Altitude range (meters) | Impact on human body | Adapt to time |
|---|---|---|
| Below 1500 | Basically no impact | No need to adapt |
| 1500-2500 | Slight plateau reaction | 1-2 days |
| 2500-3500 | Apparent plateau reaction | 3-7 days |
| More than 3500 | Risk of severe altitude sickness | 1-2 weeks |
4. Global altitude changes
According to the latest report of the International Organization for Climate Change Research, global altitude changes show the following trends:
| area | Altitude changes trends | main reason |
|---|---|---|
| Qinghai-Tibet Plateau | Increased by 0.3 cm per year | Plate movement |
| Maldives | Sea level rise threat | Global Warming |
| Netherlands | Ground settlement | Groundwater mining |
5. Things to note when traveling at high altitude
With the popularity of tourism in high altitude areas, experts recommend that tourists pay attention to the following:
1. Carry out adaptive training in advance to gradually increase the altitude of the activity
2. Prepare anti-altitude reaction drugs, such as Rhodiola, Plateau, etc.
3. Pay attention to keeping warm and warm, and the temperature difference between day and night in high altitude areas is large
4. Avoid strenuous exercise and maintain adequate rest
5. Pay attention to replenishing moisture to prevent dehydration
