Does every Zelda game start with Link sleeping?
In almost every Zelda title, Link begins the game being forcefully awoken by someone because of his lackadaisical lifestyle and sleeping habits.
Rauru's explanation for Link's slumber is that the Master Sword is supposed to only be pulled out by the one worthy of the title "Hero of Time." Link might have been able to pull it out, but Rauru explains that he was too young to actually be the Hero of Time, so his spirit was sealed for seven years, only being ...
After Link sustained fatal injuries during the second Great Calamity, Purah followed Princess Zelda's orders and placed Link in the Slumber of Restoration inside the Shrine of Resurrection to heal his wounds. Purah did so expecting for Link to lose his memories in the process.
One hundred years after the Great Calamity, Link is awaken by the telepathic call of Princess Zelda who begs him to awaken as Calamity Ganon had slowly been building up his strength to rebuild his body by siphoning Zelda's holy power as she kept him under seal and she realizes that he must be defeated soon or she will ...
According to Hyrule Historia, Link's Awakening is the sequel to A Link to the Past, Oracle of Seasons, and Oracle of Ages. It takes place in the "Downfall" split timeline after Ocarina of Time, where Ganon defeated the Hero of Time.
It features fully colorized graphics and is backward compatible with the original Game Boy. Link's Awakening DX contains a new optional dungeon, with unique enemies and puzzles based on color (due to this, the dungeon cannot be accessed on the earlier non-color Game Boy models).
4/15 Skyward Sword: A Fully Fledged Love Story
Although romance isn't new for Link and Zelda, it wasn't until Skyward Sword when the franchise would finally decide to give the two a genuine, undeniable love story.
In actuality, they almost never end up together or strike up a romantic relationship. Most of the time, Link and Zelda maintain a strictly platonic relationship with even a few instances of them simply having a professional one. The few times Link and Zelda actually wind up together are exceptions to the rule.
So in ocarina of time, when Link gets the master sword, he is put in a sleep or suspended animation or whatever you want to call it for 7 years so that he can grow into an adult and be mature enough to wield the sword (haven't played OoT enough to remember all the details, but you know what I mean).
Though this slumber lasts 100 years, Link remains the same age he was when he first entered the shrine because its properties essentially stop his aging process as he heals.
How old is Link canonically?
The official Prima Guide says that Link is supposed to be 17, and Eiji Aonuma backs that up. However, during a later interview with Nintendo Dream, Aonuma agreed with the interviewer that Link was actually 16.
According to Zelda, Link never speaks because he thinks it is “necessary to stay strong and to silently bear any burden.” If we take the diary at face value, not only does this entry explain that Breath of the Wild's Link is the strong, silent type because he doesn't want anyone to worry about him, but it confirms that ...

Like a lot of RPGs, Breath of the Wild will let the player sleep. However, Link doesn't need any beauty rest in his game—sleeping is optional. You may want to though, as sleeping will advance the clock.
The Shrine of Resurrection is a location from The Legend of Zelda: Breath of the Wild. It is located in the Great Plateau region of Hyrule. Link wakes up here in the beginning of the game.
