In fact, some people do not even realize they have rosacea because they avoid their rosacea triggers without knowing that they are doing it. This is partly because symptoms are highly irregular and there are a host of triggers that can cause the flare ups. Thus, people do not often see the connection immediately. In fact, even with more than 46 million Americans affected by the skin problem, only few know just what exactly rosacea is. Some do not even know that they have rosacea. One reason is the fact that symptoms are not regular. It is not like a disease that you will have symptoms for and it will not go away until it is cured. The most that a person can do is to manage the problem and make sure that no break outs occur. Often, people deal with rosacea by avoiding the triggers as much as they can. They always have sunglasses, umbrella and hats when they leave the house. Some do not eat spicy foods and those dishes that would trigger the symptoms. One of the main triggers is hot weather, particularly a high temperature. This is why people with rosacea do not venture out in the sun for too long. Sun exposure for a continuous and long period of time can lead to severe flare ups. Stress can also be a factor and so does spicy food, which like hot weather can raise up the temp. Unlike acne, it affects people who are between the ages of 30 and 60. Although there is no confirmed cause, Rosacea has some common triggers. When these triggers are ingested or come into contact with afflicted people, they experience rosacea symptoms. The number one among these common triggers is sun exposure. Without checking this list, finding what causes the flare ups may be like looking for a needle in a haystack. 2. Be observant When you have flare ups, check immediately what you have come into contact with or what you have eaten. This is the only way you can determine what your triggering factor is. 3.
