When choosing a holiday destination many people decide to visit warm, tropical countries, which offer not only the beauty of landscape and nature, but also lots of sun. Exposure to the sun's rays has a very positive impact on the human body, providing benefits for both body and soul. The ancient Greeks and Romans recommended that soldiers should sunbathe in order to improve fitness and bravery. It is a well-known fact that the sun increases the production of testosterone and melatonin and for that reason a suntanned hoplite could be actually more effective. What is more, the sun exhibits anti-depressant and painkilling properties, supports weight loss, production of vitamin D and regeneration of skin.
