Season 8, Episode 4 features a challenge where teams must "explain the birds and the bees" to an actual bird or bee for at least 20 seconds as part of gameplay. This is a non-graphic allusion to reproductive topics as part of a challenge task.

In Season 16, a contestant sarcasticaly says that he's watching p*rn on his phone.

In Season 2, during the "Pastry Mile" challenge, Adam vomits after eating multiple pastries. The vomiting is non-graphic, brief, and treated humorously; there is no blood, injury, or graphic content.

The show contains occasional use of strong language (e.g., curse words), some of which is bleeped in official YouTube/Nebula releases. Profanity is generally contextual and informal, used within the competitive and humorous tone of the series.

The series includes occasional alcohol consumption as part of challenge tasks. Several episodes feature contestants drinking alcohol to meet challenge requirements or in a social/travel context.

In Season 11 Slovenian teenagers ask the contestants to give them cigarettes.

The show's intensity comes from travel challenges and competitive games. While some tasks may be physically demanding or high-energy, there are no genuinely frightening or life-threatening situations; the level of intensity is mild and suitable for a general audience.
