4. Stress
If you are very stressed, then this too could lead to a flush. Chronic stress might even be the root cause of the condition in the first place!
To some, this will come as a surprise. After all, how can a psychological factor such as stress possibly have a direct impact on the appearance of your skin, which is very physical and external?
The answer is that stress actually triggers a wide variety of changes throughout the body, in particular affecting our production of hormones, which in turn can trigger a range of strange changes in the body.
In fact, it has been shown that a placebo treatment (a treatment that has no physical effect, but which the patient believes will work) has been highly effective in treating related conditions such as psoriasis.
This suggests that a useful management technique might be to learn meditation or other ways to cope better with stress!
