The sleep quality of holidaymakers improved by 17 percent while that of the nonholidaymakers deteriorated by 14 percent. The study also found the ability of vacationers to recover from stress known as the stressresilience test improved by 29 percent. There was a 71 percent fall in stress resilience scores among workers.

Key Health Markers in Holidaymakers C Box jellyfish （箱型水母） are the most poisonous marine animals known to man. They measure 3 meters long and weigh up to 2 kilograms. They are pale blue and transparent in color, and get their name from the cubelike shape of their body, Box jellyfish have 6 eyes on all 4 sides of their body, although it is uncertain how they process what they see as they do not have a central nervous system. They also have up to 15 tentacles （觸須） growing from each corner of their body that have about 5,000 stinging（帶刺的） cells each. Box jellyfish can be found primarily in the coastal waters off Northern Australia as well as throughout the IndoPacific. They prefer to live at river mouths. They do not have any ans to breathe, and will sleep on the ocean floor from 3 pm to dawn. Unlike other jellyfish that merely move along with the current, box jellyfish have developed a way to travel wherever they want to go. They will shoot themselves in a jetlike fashion, reaching speeds of up to kilometers per hour. The diet of box jellyfish consists of thing like fish, small animals, and even other jellyfish. They use their venom, a chemical which causes heart, skin, and breath failure, to kill their prey（獵物） . Since box jellyfish have eyes, some scientists believe that they actively hunt their prey while others insist that they are just passive opportunists that will wait and catch anything that wanders into their tentacles. Box jellyfish are responsible for more human deaths in Australia than snakes, sharks, and saltwater crocodiles bined. It is best to avoid them as most stings(刺 ) will result in death. Hopefully, humans and box jellyfish can find a way to live with one another while keeping conflicts to a bare minimum. After all, such a unique species of jellyfish deserves to live and grow just as humans do. 29. What do we NOT know about box jellyfish from the first paragraph? A. Its size. B. Its hardness. C.
