This Is What Happens to Your Body When You Forget to Wear Deodorant

Let's face it: It's easy to forget important steps in your morning routine when you're rushing to wake up, get dressed, eat breakfast, and leave on time. But which hygiene habits are more important than others? For instance, can you run out of the door, forget to wear deodorant, and be just fine?

According to a 2019 survey from YouGov, nearly 40 percent of young adults aged 18 to 24 say they've gone at least a month without wearing deodorant, and 31 percent of those aged 25 to 34 acknowledge doing so as well. Is that really such a big deal? Read on to find out what experts say can happen to your body when you forget to wear deodorant, and how necessary it actually is.

Deodorant by itself won't protect you from sweat. But many deodorants, such as Degree's Antiperspirant Deodorant Stick and Dove's Advanced Care Antiperspirant Deodorant, include antiperspirant—which does temporarily block your sweat glands from releasing moisture. If you stop wearing a deodorant with antiperspirant, "you may experience more sweat than normal," says Vanessa Thomas, a cosmetic chemist and owner of Freelance Formulations.

If you're not wearing deodorant or antiperspirant and you're rushing out the door, then "your sweat glands may become more active," which leads to increased secretion of sweat, says Surin-Lord. And while sweat itself can be annoying, it can also lead to bacteria build-up in your armpits, she notes.

The combination of moisture from sweat and subsequent bacteria can result in a variety of bacteria-related rashes, including erythrasma and impetigo. And these rashes could progress further than just some uncomfortable itchiness and pain. According to Medical News Today, untreated bacterial infections can actually lead to life-threatening complications such as sepsis and organ failure.

Anna H. Chacon, MD, a board-certified dermatologist and member of the board of advisors for Smart Style Today, says you should apply deodorant once a day, right after showering. "This is when it works the best, particularly before perspiring," she explains. "Sweating is predominant in the daytime over nighttime, but [even if you shower in the morning], deodorant is best applied to dry skin after showering."
