travel

The main purpose of summer tourism is to escape the heat. According to this principle, the destination of summer tourism should be the seaside and mountains.

First, their temperatures are relatively low; Coastal climate is also called marine climate. In summer, the inland sun is scorching, but the seaside is cool and breezy. Mountain climate is characterized by low temperature, but large temperature difference between day and night. Generally speaking, the temperature is inversely proportional to the altitude. Every time the altitude rises 1000m, the temperature drops by about 5℃ ~ 6℃. Secondly, the coastal and mountainous environment is pleasant: people living by the sea will feel that the wind direction will change regularly in a day and night.

Especially in the hot summer, the cool sea breeze blows on the face, which makes people feel refreshed and exhausted. In addition, the wide and soft beaches provide natural places for people to sunbathe and bathe in the sea. The unique comprehensive function of coastal climate can coordinate the functions of various tissues and organs of the body, and has certain preventive and therapeutic effects on various chronic diseases. Therefore, it is best to go to the seaside to rest in summer 10 days or so, which is very beneficial to physical and mental health.
