What's changed is basically an entire pan of medicine, the one dedicated to sleep emerged. Also, we now have a much deeper understanding of stress, or anxiety, its effect on sleep, on hormones, on the reproductive system, on rational decision making. We also have a better understanding of cortisol, the role it plays in increasing inflammation and all the problems associated with it. We also better understand how low level and punctual source of stress can also be beneficial for performances and focus, and how it is dose and duration dependant. Basically, we don't simply discard emotions as unrelated to the body anymore. We have a better and more integrated view of body and the mind and all that entails.
