Does it matter whether you breathe through your nose or your mouth? Here’s how three researchers answer.

Breathing usually happens without us having to think about it. At the same time, conscious breathing exercises can have a calming effect during anxiety or stress, but there are also breathing techniques that are not without risks.

Humanitarianism is often seen as an implicit good. The dedication to preserve, protect and support human life, dignity, and the reduction of suffering. But its implicit goodness can also stand in the way of further analysis and debate about what it contributes to in practice. That is why Centre for Health Crises at Karolinska Institutet organised just such an evening of discussion.
