THE CONVERSATION: Three reasons strong perfumes give you a headache

The fight or flight stress response is your body’s way of reacting to stress, anxiety or danger. It causes a number of physical changes, most of which are triggered by the brain going into high alert. One of the first changes you may notice during a fight or flight response is tension around the head and neck area. The reason for this is due to a vasodilation which allows more blood to be diverted to the brain and parts of the body that need it.

Our sinuses comprise of four distinct, air-filled cavities in the bones of our face. Each are lined with a mucus-secreting membrane. The mucus traps particles and bugs that come in through our nose and mouth. But in order to clear these trapped particles or potential irritants, the body needs to produce more and more mucus – resulting in allergy-like symptoms. This in turn causes our immune system to kick in and help out, which results in vasodilation and inflammation.
