WHY DOES MY SWEAT SMELL LIKE AMMONIA? HOW DO I FIX IT?

WHAT CAUSES SWEAT TO SMELL LIKE AMMONIA?

Your sweat’s sharp scent often starts with what’s happening inside your body. Here are the most common reasons behind it.

1. High-protein diet

Consuming a high-protein diet means your body breaks down more amino acids, releasing nitrogen. This nitrogen can be converted into ammonia, which your body then expels through sweat. So, if you're a fan of protein shakes or a meat-heavy diet, this might be the culprit behind that distinctive odor.

2. Dehydration

Not drinking enough water can lead to concentrated sweat, making the ammonia smell more pungent. Hydration is key in helping your body flush out waste effectively, so make sure you're sipping water throughout the day.

3. Intense exercise

Pushing your limits during workouts can cause your body to burn amino acids for extra energy, leading to that distinctive ammonia smell when you sweat. To help alleviate this odor, make sure you're using the right deodorant designed to combat strong smells, stay well-hydrated, and balance your workout intensity with proper rest.

4. Low-carb or keto diets

Low-carb diets, like keto, can alter your body's metabolism, leading to increased ammonia production. Without enough carbs, your body turns to protein for energy, which can increase nitrogen levels and, subsequently, ammonia in your sweat.

5. Underlying health conditions

Sometimes, an ammonia scent in your sweat can be a message from your body about underlying health issues. Conditions like kidney disease, diabetes, or hyperhidrosis can affect how your body processes waste, leading to an intense ammonia smell. It's essential to tune into your body's signals and consult with a healthcare professional if you suspect your sweat's scent is more than just a dietary or exercise-related quirk.

6. Stress

Stress can also play a significant role in how your sweat smells. When you're stressed, your body releases various hormones, which can lead to increased sweating and a change in the composition of your sweat. This can sometimes result in an ammonia-like odor. Managing stress through techniques like yoga, meditation, breathing exercises, and proper rest can help keep your sweat smelling fresh.

IS IT BAD IF YOUR SWEAT SMELLS LIKE AMMONIA?

During intense workouts, it's normal for your sweat to smell a bit like ammonia because of increased protein metabolism. However, if the odor persists or is accompanied by symptoms like fatigue or kidney issues, it might be time to consult a doctor.

HOW TO REDUCE SWEAT THAT SMELLS LIKE AMMONIA

Small lifestyle shifts can make a big difference when it comes to managing ammonia-scented sweat.

Drink more water

Staying hydrated helps your body flush out excess nitrogen and reduces the concentration of ammonia in your sweat. Aim for at least eight glasses a day, especially if you're active.

Adjust your protein intake

While protein is essential for muscle growth, finding a balance is crucial. Consider moderating your protein intake without sacrificing your fitness goals.

Use a pH-balanced deodorant or antiperspirant

A good deodorant can help control sweat and neutralize odors. Look for products that offer pH balance to keep your underarms fresh.

GROOMING TIPS FOR POST-WORKOUT FRESHNESS

After a workout, a cool-down shower can help wash away sweat and prevent odors. Consider using Dove Men+Care 3 in 1 Recover with Peppermint Body, Face + Hair Wash for effective odor control and lasting freshness.

FAQs

Can sweating ammonia mean I'm in ketosis?

Yes, it can. When you're following a low-carb or ketogenic diet, your body may start breaking down protein for energy, which can lead to ammonia being released through sweat. That said, individual responses can vary, and ammonia-scented sweat could also signal other factors. If you're unsure whether ketosis is the cause — or if the odor persists — it’s worth checking in with a healthcare professional to get a more complete picture.

Does ammonia sweat mean I'm unhealthy?

Not necessarily. While ammonia-smelling sweat can be normal during workouts, persistent odor might warrant a check-up to rule out underlying health issues.

Why does my sweat smell like ammonia at night?

This can happen if you're in ketosis or dehydrated. Your body may be processing protein while you sleep, especially after late workouts or meals. In some cases, it may also reflect how your body is handling waste or balancing nutrients — so if the smell is persistent or unusual for you, it’s a good idea to check in with a healthcare provider.

While ammonia-smelling sweat can be a bit surprising, understanding its causes can help you manage it effectively. Stay hydrated, balance your diet, and choose the right products to keep feeling fresh and confident.
