Herpes simplex virus type 1 (HSV-1) is responsible for reasons for cold sores. This highly contagious virus spreads through direct contact with infected individuals, most commonly through close contact, and sharing personal items of the infected individuals.
Beyond the specific cause of the herpes simplex virus type 1 (HSV-1), several causes can increase the likelihood of developing or experiencing a cold sore outbreak, they are:
Stress: Emotional and physical stress can weaken the immune system, making you more susceptible to various infections, including cold sores.
Fatigue: Lack of sleep and exhaustion can compromise the immune system's ability to fight viruses, potentially triggering an outbreak.
Illness: Any illness, even a common cold or the flu, can weaken the immune system and create an environment conducive to a cold-sore outbreak.
Fever: A rise in body temperature associated with illness can trigger the virus and lead to an outbreak.
Changes in hormones: Fluctuations in hormone levels, especially during menstruation or pregnancy, can affect the immune response and potentially trigger outbreaks in some individuals.
Nutritional deficiencies: Deficiencies in certain vitamins, like vitamin B12 or zinc, can contribute to a weakened immune system and increase susceptibility to viral infections, including cold sores.
Before addressing the home remedies, one has to know how long does cold sore lasts. The average lifespan of a cold sore is 7-10 days. However, the first outbreak can sometimes last longer, up to two weeks. However, the below home remedies for cold sores can bring relief and faster recovery:
