Yes, you will likely start to smell after not showering for 3 days because bacteria on your skin feed on sweat and oils, producing odor, and dead skin/dirt build-up creates a breeding ground for stronger smells and potential skin issues, though how much depends on your activity and body chemistry. While some people might manage longer, by day 3, many notice oily hair, greasy skin, and a distinct body odor that others can smell.
``Some adults who go longer than 3-4 days between showers run the risk of accumulating patches of dark, scaly skin, especially in oily areas, and an accumulation of 'bad' bacteria which can lead to fungal or bacterial infections,'' adds Dr. Young.
Practice Good Hygiene: Regular showers and changing clothes daily, especially after sweating, are essential for managing body odor. Exfoliating your skin occasionally can also remove dead skin cells that may contribute to odor.
You're covered with bacteria. They eat your skin oils and sweat and then excrete waste that smells. What causes your body to smell is an accumulation of bacteria poop.
Usually, this happens when females are 8–13 years old, and males are 9–14. But it can also be normal to start puberty earlier or later. Bathing every day, especially after a lot of sweating or in hot weather, can help with body odor. So can wearing clean clothes, underwear, and socks each day.
This stage usually lasts between 24 and 72 hours. Then comes the three-to-five-day bloat stage, during which escalating bacterial activity causes the body to swell, and the stench of decomposition becomes apparent. These unpleasant odors increase during active decay, which typically begins seven to 10 days postmortem.
Take off your clothes and smell around the armpit or wherever you sweat. You can also hold your hand against your mouth, breathe out, and smell your breath to see if it smells stinky. If you have someone you trust around, you can tell them you're worried that you smell bad and ask them to check.
You'll smell bad
This is certainly a key point for anyone with friends: if you stop washing, it's pretty likely that you'll start to smell bad. Even if you don't sweat excessively, strong body odor will doubtlessly develop and your refusal to shower will prevent you from eliminating it.
If you sense a little body odor, it's because your pubic hair is doing its job of trapping sweat, oil, and bacteria.
However, when it comes to fruit and vegetables more widely, eating more of them can lead to a more attractive scent. A 2017 study in Australia found that men who had consumed more fruit and vegetables were significantly associated with smelling better – more fruity, floral and sweet.
The hardest smells to get rid of are often deeply embedded, like skunk spray, cigarette smoke, pet urine, mold/mildew, and fire/water damage odors, because they permeate porous materials (carpets, upholstery, drywall, synthetic fabrics) and can get into HVAC systems, requiring professional cleaning or specialized ozone treatments to neutralize the odor molecules themselves, not just mask them.
The weather where you live can affect how often you need to shower. Temperature, humidity, and seasonal changes all impact sweat, oil production, and skin dryness. Shower daily to rinse off sweat and prevent body odor or clogged pores. Consider a second quick rinse if you sweat heavily during the day.
Other Body Odor Treatments
Try a solution of hydrogen peroxide and water to fight body odor. Use 1 teaspoon of peroxide (3%) to 1 cup (8 ounces) of water. Wipe this on affected areas (underarms, feet, groin) with a washcloth. This may help destroy some of the bacteria that create odor.
There's no one-size-fits-all answer to this question. Many doctors say a daily shower is fine for most people. (More than that could start to cause skin problems.) But for many people, two to three times a week is enough and may be even better to maintain good health.
Hygiene is often difficult for individuals who have ADHD due to their brain and body differences. Tasks like showering and brushing teeth are low-reward activities that involve sensory input that doesn't always feel good.
One of the most significant factors influencing the avoidance of showers is mental health. Conditions like depression can severely impact motivation and energy levels. Individuals experiencing depression often find even the simplest tasks daunting, leading to neglect of personal hygiene.
With less hair, there's less surface area for bacteria and sweat to cling to and deodorants may apply more evenly on smooth skin. So yes, shaving armpits can reduce odor, especially when paired with good hygiene.
Dr Rosén says that it usually ranges from a slightly tangy or sour smell to a more metallic smell around or after your period. 'Generally, if you're feeling well and your vaginal odour or discharge isn't unusual for you, there's no reason to worry.'
Grooming Optimizes Hygiene
Shaving your pubic hair, or even slightly trimming it, helps keep your goods cleaner by exposing skin to soap and water that's normally covered by hair. Pretty simple.
After you've been sweating, give your shirt, socks, or any other garment a sniff, especially in areas prone to odor like your underarms, feet, and groin. If your clothes smell bad after a short time, it's a good indicator that you have body odor.
Cheesy or sour: Similar to the smell of aged cheese or fermented foods due to the breakdown of sweat proteins by bacteria. Onion-like or garlicky – Especially if certain foods are a contributing factor.
5 Bathing Alternatives For Seniors At Home
To a certain extent, it's normal to have a fear of smelling bad. However, if this fear is causing intense anxiety that keeps you from interacting with others, you might be dealing with a specific phobia, social anxiety disorder (SAD), olfactory reference syndrome (ORS), or obsessive-compulsive disorder (OCD).
Different categorizations of primary odors have been proposed, including the following, which identifies 7 primary odors:
Use antiperspirants and deodorants: Antiperspirants work by reducing the amount of sweat that is produced, while deodorants mask odor. Hydrate, hydrate, hydrate! Drinking plenty of water can help flush out toxins and reduce body odor. Aim to drink at least eight glasses of water a day.
