If you watch the cooking shows with Gordon Ramsey dealing with kids, you would get half of it. He's amazing with youngsters, and k ows exactly how to give them positive motivation. He saves his outbursts for the "professionals" who are being complete idiots. He also racks it up for American TV. He's a lot more relaxed on UK TV.
The series where he cooks in his own home was very relaxed. I only managed to watch American Hell's Kitchen for a single episode - it feels like torture.
The networks have a lot to do with this. The exact same recording on BBC is way less stressful than on FOX. The FOX versions are edited for maximum drama. I used to watch all of Gordon's stuff and I hated watching the FOX versions.
