Body odor is natural part of human physiognomy, while some people may experience less of it, it can be stronger in others. This odor is not uniform throughout your body, certain body part smell more, like your armpits, groin and feet. The Cleveland clinic explains that this smell is due to bacteria and smell on your skin. Your body odor can also change if you are on medication, or ate a certain food or even experience some hormonal changes.

Similarly, It's common for belly buttons to have a slight odor, but sometimes it can become noticeable and unpleasant. While a little smell is often nothing to worry about, a strong, foul odor, especially when combined with other symptoms, could be a sign of a more serious problem. It's important to understand the possible causes of a smelly belly button so you can take the right steps to address it. Knowing when to simply clean it better versus when to seek medical help is key to keeping yourself healthy.

Possible Causes of Belly Button Odor

If your belly button smells bad and you also have redness, swelling, pain, or bleeding, you should see a doctor. These symptoms could be a sign of an infection that needs medical treatment Here are some reasons why this may be happening.

Not Cleaning It Well

Just like any other part of your body, your belly button needs regular cleaning. If you skip cleaning it with soap and water, things like dirt, sweat, and natural oils can build up inside. As explained above, his buildup creates a breeding ground for bacteria, which can lead to a musty or unpleasant smell. This is especially true if you have a deep belly button, as it has folds and crevices that are harder to reach and clean properly. A deep belly button is a warm, damp place, which is exactly what bacteria love.

Stuff Getting Stuck

Even if you take regular showers, your belly button can still collect things like dead skin cells, lint from your clothes, and other small pieces of debris. WebMD explains that these things can get trapped inside, and when mixed with moisture from sweat or water, they can start to smell bad. Sometimes, these things can clump together and form a hard, smelly lump called a navel stone. This stone can be quite smelly, even though it's usually not painful.

Bacterial Infections

We all have bacteria on our skin, but sometimes they can cause infections. According to WebMD if bacteria get inside your belly button, especially through a small cut or scratch, they can multiply and cause an infection. Infections like impetigo and cellulitis can cause redness, swelling, pain, and pus, along with a bad smell. People with weak immune systems or poor blood flow are more likely to get these infections. If these infections are not treated, they can lead to serious problems, so it's important to see a doctor.

Yeast Infections

Yeast, which is a type of fungus, can also grow in your belly button, especially if it's warm and moist. According to the Cleveland Clinic a common type of yeast is Candida. Yeast infections can cause a sour, bread-like smell, along with redness and itching. Sweating a lot, wearing tight clothes, or taking antibiotics can increase your risk. People with diabetes or weak immune systems are also more likely to get yeast infections. These infections usually go away with antifungal creams, but it's important to keep the area dry to prevent them from coming back.

Cysts

Cysts are small, fluid-filled bumps that can form under the skin. They can happen when dead skin cells and oils get trapped in your belly button. Most of the time, these cysts are harmless and don't cause any problems. But sometimes, they can become infected, which can cause them to swell, become red, and release a gray or white discharge with a cheesy smell. If a cyst gets infected, it might need to be drained by a doctor.

Piercings

If you have a belly button piercing, it's very important to keep it clean. If you don't clean it properly, bacteria can build up around the piercing and cause an infection. Signs of an infection include pain, redness, swelling, and smelly pus. If the infection is not treated, it can spread to your bloodstream and cause serious health problems. Cleaning your piercing regularly with warm, soapy water can help prevent infections.

Even as heatwave conditions continue to intensify across parts of the country, cases of heat-related illnesses are on the rise, leaving many confused between heat stroke and heat exhaustion.

While both are caused by prolonged exposure to high temperatures, their severity, warning signs, and management can differ significantly.

Speaking to HealthandMe, Dr. Naval Vikram, Professor, Department of Medicine, at the AII India Institute of Medical Sciences (AIIMS), explained the key symptoms to watch out for, how to tell the difference between the two conditions, and the simple yet crucial steps individuals can take to protect themselves during extreme heat.

“The general features of a patient with heat stroke are: first, his or her body temperature will be very high. It will not be around normal levels like 104, 105, or 106—it will be significantly elevated. Second, the person may be delirious, confused, or even in a state of unconsciousness or coma. The breathing will also be labored. These are the features of heat stroke,” Dr Vikram said.

On the other hand, a person with heat exhaustion remains conscious, but looks and feels very tired. The individual is also likely to experience

• body ache,
• muscle pain,
• headache,
• muscle cramp,
• body pain or fatigue.

"If this has happened after exposure to heat, it is similar to the feeling one gets after jogging, running, or playing for about half an hour and then feeling exhausted. If that same feeling occurs without doing any such activity, then it is a stage of heat exhaustion, because it is happening due to the heat,” Dr Vikram told HealthandMe.

Who Is More At Risk With Heat-related Problems?

The most vulnerable category for heat-related problems is the extremes of age—the younger children and older adults.

The expert noted that younger children may not be able to express their symptoms completely. They may not be able to tell you exactly what they are feeling.

At the other end, older adults often have multiple health issues—neurological conditions, diabetes, hypertension, and kidney problems.

"So multiple organs may already be affected to some extent. In such situations, if heat-related illness occurs, it becomes difficult to diagnose, especially if they already have neurological problems like confusion or altered behavior," Dr Vikram said.

With existing comorbidities, other organs may already be compromised, so the tipping point towards severity happens very quickly. In contrast, younger individuals generally have greater body reserves.

Therefore, people at the extremes of age are more vulnerable, also because it can sometimes be difficult to recognize and diagnose the condition in them.

How Can One Prevent?

While it may be impossible to avoid rising temperatures, the focus should be on how much you can protect yourself. The expert suggested measures such as:

• Try to avoid exposure to extreme heat as much as possible.

• In case of being exposed, make sure to cover yourself—cover your head and upper body, use an umbrella, stay hydrated, and take breaks in between.

• If you have to work in a hot environment for a couple of hours, take a break in a cooler or temperature-controlled environment for at least half an hour before resuming, rather than continuously working in the heat. These steps can help prevent heat-related problems.

• If symptoms do occur, and it is heat exhaustion, take rest and avoid further activity for some time.

• In more severe cases—if someone shows symptoms like loss of consciousness or very high body temperature—they should be taken to a hospital immediately. Do not try to manage such cases at home.”

Complex pesticides can be now be found in food, water and the surrounding environment and while previous research has noted that they can cause damage to vital organs, a new Nature Health study has revealed that high-exposure to such chemicals can increase a person's risk of certain cancers by over 100 percent.

The researchers analyzed 31 pesticides across Peru and compared the health data from more than 150,000 cancer patients recorded between 2007 and 2020 with areas to discover that people living in regions with higher environmental pesticide exposure were 150 percent more at risk of developing cancer. It remains unclear which kind of cancers they are most prone to.

Stéphane Bertani, a researcher in molecular biology at the French National Research Institute for Sustainable Development (IRD), at the PHARMA-DEV laboratory (IRD/University of Toulouse) said of the results: "This is the first time we have been able to link pesticide exposure, on a national scale, to biological changes suggesting an increased risk of cancer."

The study also highlights how pesticide exposure may affect the body long before cancer is diagnosed. Although tumors can develop in different organs, some share underlying biological weaknesses tied to their cellular origins and vulnerabilities which may be influenced by pesticide exposure.

Previous studies conducted at the Institut Pasteur, led by Pascal Pineau, also show that pesticides can slowly interfere with processes that maintain normal cell function and identity.

Over time, these disruptions accumulate without obvious symptoms and make tissues more susceptible to other harmful influences, including infections, inflammation and environmental stress, paving the way for cancer development.

Pesticides Can Also Increase Risk Of Lung Cancer

The research from the University of Southern California, presented at the annual meeting of the American Association for Cancer Research, found that patients under 50 diagnosed with lung cancer often had better-than-average diets. The experts zeroed in on the culprit, pesticide exposure from conventionally grown produce.

"Our research shows that younger non-smokers who eat a higher quantity of healthy foods than the general population are more likely to develop lung cancer," said lead investigator Jorge Nieva, a medical oncologist and lung cancer specialist with USC.

"These counter-intuitive findings raise important questions about an unknown environmental risk factor for lung cancer related to otherwise beneficial food that needs to be addressed," Nieva added.

Pesticides In Healthy Foods — A Hidden Risk

According to the researchers, the reason may lie in environmental exposure, particularly pesticides used in agriculture. Nieva noted that commercially produced (non-organic) fruits, vegetables, and whole grains are more likely to carry higher levels of pesticide residue compared to dairy, meat, and many processed foods.

He also pointed out that agricultural workers who are regularly exposed to pesticides tend to have higher rates of lung cancer, which supports the possibility of a connection.

The study also found that young women who do not smoke are diagnosed with lung cancer more often than men in the same age group. Women in the study also tended to consume more fruits, vegetables, and whole grains than men.

Kidney stone incidences increase significantly in the summer months; the main reason for this increase is the effect of summer on people's hydration levels. As we get hotter, we sweat a lot, and when we sweat, we lose fluids. If we don't drink enough fluids to replace what we have lost through sweating, our urine will become more concentrated.

Concentrated urine provides a good environment to crystallize minerals, calcium, oxalate, uric acid, and eventually create stones.

In hot weather, it is easy for people to think that they don't need to drink as much water as they really do. The effects of mild dehydration can have a major impact on how many liters of urine a person produces, which is one of the most significant contributors to protecting against developing kidney stones.

When urine production decreases, waste products in the urine become less diluted, so the chances of forming crystals are increased. People who do not exercise much or who don't pay attention to their hydration habits can be at greater risk than others for developing kidney stones.

Poor eating habits in the summertime can add to the problem. Increasing your consumption of salty and processed foods can raise your calcium excretion in the urine, leading to more stones. A high intake of animal protein can increase your uric acid level and decrease your citrate level, a natural inhibitor of stones. Many people will also reduce the amount of fluids and water-rich foods they consume when travelling or working, which further increases the risk of developing stones.

Another factor that isn’t frequently considered is delaying urination. Holding urine for long periods will cause the minerals to settle in the urinary tract and may crystallize, which increases the likelihood of developing stones. Delaying urination in combination with dehydration provides the ideal environment for the formation of stones.

It is important to know and recognize the early symptoms of kidney stones so that you can seek help in a timely manner. Symptoms to watch for are:

• Severe flank pain (back or side),
• burning sensation when urinating,
• nausea and vomiting,
• blood in urine.

Failure to seek treatment for these symptoms can result in complications, such as urinary tract infection or obstruction due to kidney stones.

There are several commonly used methods of preventing kidney stones during the summer months, and they involve very basic lifestyle changes. Consistently drinking enough water so that your urine is clear or light in color is the single most important thing you can do to avoid a kidney stone.

Limiting your intake of additional salt and moderating your animal protein consumption will help as well. Including citrus fruits (lemons and oranges) in your diet may also prevent kidney stones, because they contain citrates, which help to inhibit the formation of kidney stones.

By using proper hydration, good nutrition, and an awareness of the early warning signs of kidney stones, your kidney stone risk will be considerably lowered throughout the summer months.
