Whether it's a vacation or a honeymoon, many people's first choice is to go to an island. Sun, sand, waves... A simple beach seems to be filled with countless happy elements.

A variety of water activities such as surfing and diving can release our nervous body and mind, and even just lying on the beach and listening to the sound of the waves is enough to make us feel good.

Many people want to go to the beach for a walk when they are sad. Looking at the endless ocean and listening to the sound of the waves hitting the beach, the originally messy thoughts will gradually become clear. Does the sea really have a magical power?

Stressed urbanites have been fleeing to green spaces in recent years as green spaces have been shown to have positive effects on physical and mental health, but the benefits of "blue spaces" (which include oceans and coastlines, as well as rivers and lakes) have not been reaped good publicity, but the scientific community actually has a consensus for at least ten years: staying at the seaside is also good for people's body and mind.

The body absorbs the negative ions released by the waves, allowing the body to absorb more oxygen and regulate serotonin. Serotonin is an anxiety-controlling substance that induces feelings of peace and calm, so looking at the sea can bring happiness.

Studies have also found that when we sunbathe on the beach, the heat affects the endocrine system, releasing endorphins (the chemicals that make you feel happy after eating chocolate), making you happy.

Here are some of the world's most beautiful seas, some of which you can choose to visit when you are in a bad mood.

Aegean Sea

The Aegean Sea is a blue ocean east of the Greek Peninsula, part of the Mediterranean Sea. The Aegean Sea is the only water that the countries along the Black Sea must pass through to the Mediterranean Sea, the Atlantic Ocean and the Indian Ocean. It has an important position in shipping and strategy.

The Aegean Sea is 610 kilometres long from north to south and 300 kilometres wide from east to west. The coastline is very tortuous and there are many harbours. The Aegean Sea is not only the cradle of Western civilization but also the symbol of romantic journeys for tourists from all over the world.

Arabian Sea

The Arabian Sea has been affected by seasonal winds for a long time, so there are often violent storms. It's very rich in mineral and biological resources, and you can see Marine life that you've never seen in your life. Here you can hear the call of the sea and get away from the hustle and bustle of the city.

Coral Sea

With a total area of 4.791 million square kilometres, the Coral Sea is the largest in the world. The Coral Sea is named for its large number of coral reefs, the most famous being the Great Barrier Reef, which is located in this sea area. The water of the Coral Sea is high in salinity and clarity, and the water is a deep blue colour.

The power of the sea extends beyond its physical beauty. Its capacity to rejuvenate and heal both body and mind is unparalleled. The negative ions in the sea air, the rhythm of the waves, and the warmth of the sun all contribute to a sense of well-being and tranquillity.

So, whether you choose to visit the serene Aegean Sea, the stormy yet fascinating Arabian Sea, or the vast and vibrant Coral Sea, you are sure to experience the wonderful power of the sea.
