Unclean living can be a smart idea for everyone, not just kids. These unusual strategies may strengthen your microbiome. We depend on a vast army of microbes to stay alive: a microbiomes protect us against germs, breaks down food to release energy, and produces vitamins.

Don’t shower every day if you can get away with it
This may help protect your skin biome, which acts as a protective coating against pathogens.

Forgo antiperspirants on weekends or on days you can go without them
Believe it or not, your armpits harbor their own special microbial colonies.

Dry-brush instead of using toothpaste
The chemicals in most pastes disturb your oral biome, and research suggests that dry-brushing actually fights plaque more effectively. Skip the mouthwash, too for the same reasons.

Walk barefoot through the grass
It not only feels great and relieves stress but also help your foot microbes flourish. Keeping your feet in shoes and socks all the time kills the good bugs and brings on the stinky ones.
