Persistent Body Odor: Sweat, Diet, or Infection-Related Causes Explained

Date: 24 Feb 2026

Everyone sweats — it’s normal and healthy. But when body odor becomes persistent, strong, or unusual, it can be uncomfortable, embarrassing, and even distressing.

If regular bathing and deodorant don’t seem to help, there may be more going on beneath the surface.

Persistent body odor is not always about poor hygiene. In many cases, it’s linked to how your body sweats, what you eat, or underlying infections. Understanding the cause is the first step toward finding an effective and lasting solution.

This guide explains the real causes of body odor, how to manage it safely, and the best deodorant and hygiene solutions available in Kenya.

 

What Actually Causes Body Odor?

Here’s an important truth: sweat itself is odorless. The smell develops when sweat mixes with bacteria on the skin.

Your body has two main types of sweat glands:

  • Eccrine glands, which regulate temperature
  • Apocrine glands, found in areas like the armpits and groin, which produce thicker sweat that bacteria love

When bacteria break down this sweat, unpleasant odors develop — and sometimes they linger.

 

Sweat-Related Causes of Persistent Body Odor

Excessive Sweating (Hyperhidrosis)

People who sweat more than average create a moist environment where odor-causing bacteria thrive. This can lead to constant body odor even after bathing.

Poor Air Circulation

Tight clothing, synthetic fabrics, and hot weather can trap sweat and bacteria, worsening odor — a common issue in warm climates like Kenya.

 

Diet-Related Causes of Body Odor

What you eat can directly influence how you smell.

Foods That Can Worsen Body Odor

  • Garlic and onions
  • Red meat
  • Alcohol
  • Spicy foods
  • Processed foods

These foods contain compounds that are released through sweat, altering body scent.

Hydration Matters

Not drinking enough water concentrates sweat, making odors stronger and harder to control.

 

Infection-Related Causes of Body Odor

If body odor has a strong, unusual, or persistent smell, it may be due to an infection.

Bacterial Skin Infections

These can cause foul-smelling sweat, redness, and irritation, especially in skin folds.

Fungal Infections

Common in the feet, groin, and armpits, fungal infections often cause a musty or sour odor that doesn’t improve with deodorant alone.

When to Suspect Infection

  • Odor persists despite good hygiene
  • Itching, redness, or peeling skin is present
  • The smell is unusually strong or different

In these cases, medical treatment is essential.

 

How to Effectively Manage and Prevent Persistent Body Odor

1. Maintain Proper Hygiene: Daily bathing with antibacterial soap helps reduce odor-causing bacteria.

2. Choose the Right Deodorant: Antiperspirants reduce sweat production, while deodorants neutralize odor. For persistent odor, antiperspirants are often more effective.

3. Wear Breathable Clothing: Cotton and moisture-wicking fabrics allow sweat to evaporate instead of being trapped.

4. Treat Underlying Infections Promptly: Ignoring fungal or bacterial infections allows odor to persist and worsen.
