In this, i will consider some several principles to explain this.
1. Geographers have proven that, within the atmosphere we live in, the higher you go, the cooler it becomes.
2. Physicians have proven that, the higher the temperature, the higher the pressure.
Compining these two principles therefore, it shows that a, the high land where the person is standing is cooler that a low land. Due to the cold, the place is experiencing, it is therefore under low pressure.
3. scientists have also proven that, matter tend to flow from a region of high pressure to a region of low pressure at a rate determined by their viscosity and weight.
Therefore, to the man on a high land, blood will flow from inside him (a region of higher pressure) to the surrounding (region of low pressure, hence nose bleed.
