Your lifestyle can play an important role in the management of cold sores. By making certain lifestyle changes, you may be able to reduce the number of outbreaks you have. You may also reduce the symptoms and their severity.
Exposure to sunlight is known to cause outbreaks of cold sores. Although it is impossible to avoid all sun exposure, use sunscreen on your lips and skin to help reduce the sun’s effect. Also, whenever you go outside in sunny weather, wear a large-brimmed hat to protect your face from the ultraviolet rays.
Reduce Physical and Emotional Stress
Physical and emotional stress may reduce the body’s ability to fight herpes simplex virus (HSV) and trigger an outbreak of cold sores. Although exercise may actually help to reduce emotional stress, an excessive amount can weaken the body.
, such as
and deep breathing, can help reduce emotional stress.
Practice Good Hygiene
Good hygiene can prevent the spread of cold sores and help reduce the length and severity of the outbreaks. During an outbreak:
Avoid touching the sores, especially avoid contact with any open cuts on your skin.
Take care not to spread the virus to other parts of your body, such as the eyes and genital area.
Avoid Certain Foods
Foods that irritate the tissue of the lips and mouth, such as certain fruit or spices, may trigger a cold sore outbreak. These food-related “triggers” are different for every person. Be aware of your food triggers and avoid them.
Get Adequate Sleep and Eat a Healthful Diet
The body heals fastest when it receives rest and good nutrition. Strive for a good night’s sleep, along with a balanced, healthful diet on a daily basis.
