Remember all those stressful moments when you thought that you would not be able to make it through; like your examinations, a project deadline at work, or continuous work stress without rest, etc.
This is basically a repeated cycle in which people often suffer with an illness or develop flare-ups of a chronic condition.
It has been observed that the tendency of panic attacks is usually more on weekends than on weekdays and people tend to get more hyper and lose control of their mental conditions.
Our body is very adaptive to situations and in situations when there is excess stress the body releases hormones like glucocorticoids (like cortisol), catecholamines (like norepinephrine) and adrenaline.
While this phenomenon is going on, hormone called glucocorticoids can fuel up latent viral infections such as herpes simplex 1 causing cold sores and Epstein-Barr virus that usually results in fatigue, fever, sore throat and swollen glands.
These symptoms usually start to show after a few days as explained by behavioural neuroscientist.
