You may be setting yourself up for a cold sore outbreak without even knowing it

Nightmare scenario time: You're getting ready for a big event or a date. You have a cute new outfit. Your hair is lookin' fly. Your makeup's on point. Only one problem. That little tingle you were feeling in your lip the other day? It's a full-on cold sore now, and no amount of concealer is going to cover that up.

It's possible for just about anyone to get a cold sore — according to the Mayo Clinic, a kind of terrifying 90 percent of adults worldwide test positive for the strain of herpes simplex virus, HSV-1, that causes cold sores.

While the vast majority of people who carry HSV-1 are asymptomatic and rarely, if ever, experience outbreaks, for others, cold sores can be an embarrassing nuisance that flares up unexpectedly. For those who suffer from cold sores, there are some things that can trigger outbreaks, and while some of them are unavoidable, others can be managed.

Stress is one trigger that can be managed. Being stressed out also wreaks havoc on our bodies in other ways, so trying to keep stress under control has benefits other than lowering your chances of getting cold sores. Try calming activities like meditation or spending time with friends.

4. Hormonal changes

Some of the hormonal changes that are likely to cause cold sore outbreaks are related to menstruation, and so they aren't easy to control. However, some kinds of birth control eliminate periods and may also help with the hormonal changes that cause some women to get cold sores when they get their periods.
