Keep in mind that not all of these things will trigger your rosacea. Everybody is different. The important thing is to learn what causes your own rosacea symptoms. You can use a diary to keep track.

Why Do Triggers Make Rosacea Worse?

Doctors still aren't sure what causes rosacea, but in a lot of people, things that make your face flush also make rosacea worse.

When you flush, blood rushes to your face, making it red and warmer. So avoiding activities, products, or emotions that cause flushing can reduce your rosacea symptoms.

Avoiding Rosacea Triggers

Once you've figured out what your rosacea triggers are, find ways to avoid them.

Food and drinks. Don't eat foods that cause rosacea symptoms. You could also try some simple substitutions. For instance, in the morning, replace that steaming mug of coffee with iced coffee.

Exercise. Unfortunately, working out can worsen your rosacea. But you still need to be physically active. So change your routine. Instead of one long workout, try splitting it into several shorter segments. Try longer, low-intensity workouts instead of more demanding ones. And stay cool. Don't exercise outside when it's too hot. If you're inside, use a fan or air conditioner. During your workout, drink plenty of water. Afterward, cover your face with a cool cloth.

Weather. You should always wear a hat and use sunscreen to protect your skin while outside. Also, do the obvious: dress warmly on cold days and lightly on hot ones.

Emotional stress. Learn ways to calm yourself before stress results in a rosacea flare-up. You might try deep breathing exercises or yoga.

Medication. If you think a medicine may be a trigger, talk to your doctor. See if you could take a different drug.
