Examples of human adaptation in different climatic zones are needed.

The human body is designed so that it can adapt to any living conditions. Our ancestors, when they led a nomadic lifestyle, did it often. It is more difficult for a modern person to get used to a different climate (most people are used to comfort). Where there is another climatic zone, a person will feel it. For example, excessive heat causes dizziness, shortness of breath, and weakness. The mountainous zone causes exacerbation of diseases, dizziness. Excessive cold affects a person negatively. To adapt to a different climate, a period is required (at least 14 days).
