 |
Extreme temperatures like cold or especially heat (as in a sauna or while taking a hot bath) cause physiological flushing and may trigger rosacea. Hence, they should be avoided.
|
2. ultraviolet radiation:

|
Frequently rosacea is associated with sun-damaged skin (solar elastosis), which seems to be a triggering factor. Hence, especially patients with rosace should avoid ultraviolet radiation like sun baths.

|
Emotional stress due to embarrassment or anger may induce flushing, which is a precursor of rosacea.
|
4. alcoholic beverages:

Already small quantities of alcohol induce vasodilation, which may cause intensive flushing. As flushing is an important trigger rosacea patients should abstain from alcohol.
|
5. spiced food:

6. hot drinks:

Hot drinks induce flushing due to the effect of rise in blood temperature. As flushing is an important trigger rosacea patients should avoid hot drinks.
