The belly button marks the exact spot where your umbilical cord was once attached—the vital connection that provided oxygen and nutrients in the womb. Once you started breathing, eating, and discharging waste on your own, this cord was no longer needed. What remains is a mark, a reminder of your months in your mother’s womb. However, it often gets ignored as you grow up. And there is nothing wrong with that. Your belly button does not require a special skincare routine, but neglecting its hygiene can lead to a buildup of bacteria, potentially causing a smelly discharge.

But generally, a discharge from your belly button is normal and colourless. According to experts, normal discharge is typically clear or light-coloured, has a slight odor (similar to sweat), and has no pain or redness around the navel.

What happens when you get a Bacterial or yeast infection in the belly button?

Experts say that the most common funk you might encounter in your belly button is a bacterial or fungal infection. A study titled

A Jungle in There: Bacteria in Belly Buttons are Highly Diverse, but Predictable published in 2012 in PLOS One Journal states that once rarefied to four hundred reads per sample, bacterial communities from belly buttons proved to be at least as diverse as communities known from other skin studies (on average 67 bacterial phylotypes per belly button).

This occurs due to poor hygiene, excessive sweating, or trapped moisture. Other conditions include navel piercings, cysts, and skin conditions like eczema or psoriasis. People with diabetes are particularly susceptible to fungal infections such as candidiasis if their blood sugar isn't under control, according to a 2019 review in the Journal of Clinical Medicine.

Bacteria and fungi love the dark environment of your belly button. If your belly button is infected, you might notice some redness or swelling. The discharge might look like pus, making your belly button smell bad. If it's a yeast infection, your belly button might also itch.

What happens when your navel piercing gets wrong?

Belly button or naval piercing, if infected, can lead to severe pain, discolouration, swelling, discharge and pus. It can also cause the skin to appear red, causing delayed or failed healing.

Other common signs include:

Chills or fever

Persistent pain or inflammation

Sensitivity or discomfort when moving

Swelling or tenderness to touch

When Should You See A Doctor?

As pollution season creeps back in Delhi, N95 masks outdoors and air purifiers are once again most likely to become the primary go-to protective measures for the public.

Both are known to lower exposure to harmful particles significantly, but neither can completely nullify the health risks of polluted air. So before you invest in an air purifier or buy a dozen N95 masks, understand how much you will be protected as you step out during smog everyday.

How Much Protection Does An N95 Mask Offer?

A properly fitted N95 respirator can filter at least 95% of airborne particles under standard environment. That makes it substantially more protective against fine particulate matter like PM2.5 than regular surgical or cloth masks.

But just wearing an N95 does not mean you are breathing toxins-free air. Its effectiveness depends heavily on fit. Gaps around the nose, cheeks or chin can let polluted air to bypass the filter.

An N95 also does not protect equally against every pollutant. It is designed primarily to filter particles, not gases like nitrogen dioxide or ozone. So if you spend most of your time outdoors during severe pollution, wear a well-fitted, certified respirator to reduce exposure.

Protection from PM2.5 is key as these particles are small enough to seep deep into your lungs and, in some circumstances, even cross over to enter the bloodstream. Long-term exposure to PM2.5 has been associated with cardiovascular disease, respiratory disease and other serious health problems.

Is An Indoor Air Purifier Enough To Tackle Outdoor Pollution?

The effectiveness of an air purifier depends significantly on the purifier, the size of the room and how it is used. A purifier equipped with a HEPA filter can remove fine particles from indoor air. When outdoor PM2.5 levels are high and polluted air enters homes through windows, doors and ventilation systems, this could be one of the best ways to protect yourself.

However, simply switching on a purifier in a large room does not guarantee clean air. The purifier needs to have sufficient clean air delivery rate (CADR) for the size of the room.

Keeping doors and windows closed during periods of extreme outdoor pollution can also help reduce the amount of polluted air entering. Filters need to be replaced according to the manufacturer's recommendations because a heavily loaded filter can reduce performance.

One of the limitations is that HEPA filtration primarily addresses particles. A purifier needs additional technologies, like an activated-carbon filter, to reduce some gaseous pollutants, and even then it cannot remove every pollutant completely.

For Delhi's pollution season, these two measures address different exposure issues. N95 masks help reduce inhalation of polluted particles while outdoors. Air purifiers help lower indoor concentrations of particulate matter. Using both can therefore provide greater protection than relying on either measure alone.

People with asthma, COPD, heart disease or other respiratory and cardiovascular conditions, as well as children and older adults, can be more vulnerable to the effects of air pollution.

Even healthy people can experience symptoms like coughing, throat irritation, wheezing, eye irritation and breathing discomfort when pollution levels rise.

Dry eyes are common among people who spend long hours on screens, and lubricating eye drops are often used for relief. But using the wrong drops, keeping an opened bottle for too long or even sharing eye drops can create problems.

Estimates suggest that up to 50% of adults experience dry-eye symptoms, making artificial tears a common part of self-care. But persistent symptoms should not simply be treated indefinitely without identifying the underlying cause.

So, how often can you use eye drops, and what should you keep in mind?

We spoke to Dr. Ritika Sachdev, Director at Centre for Sight, New Delhi, to understand the common mistakes people make while using eye drops.

Eye Drops For Dry Eyes: When Should You See A Doctor?

Dr. Ritika said persistent or bothersome dry eye symptoms should be assessed by a doctor because dryness can have several causes.

These may include:

• Eyelid inflammation
• Allergies
• Contact lens use
• Makeup
• Incorrect spectacle power causing eye strain

“Sometimes even not wearing your right spectacle power contributes to eye strain which can be misread as dry eye,” she said.

Lubricating drops can help support dry eyes, but prolonged use should be discussed with an eye specialist.

Several eye-drop products have been recalled in the US in recent years over contamination and other safety concerns. This makes proper storage, handling and hygiene particularly important when using eye drops.

Dr. Ritika cautioned that some eye drops contain preservatives that may worsen dryness when used for a long time.

“Many of the eye drops have preservatives which if used over a long period of time actually cause more dry eye,” she said.

According to her, preservative-free drops or those with very mild preservatives may be preferable for people who need regular use.

Don't Keep An Open Eye Drop Bottle Forever

"Once opened, an eye drop bottle can become contaminated if it is not handled or stored properly," Dr. Ritika said.

The expert advised:

• Note the date when you open the bottle.
• Follow the product's storage instructions.
• Do not let the bottle tip touch your eye.
• Discard the bottle according to the manufacturer's instructions.
• Do not continue using an opened bottle indefinitely.

“Once the bottle is open, it often may get contaminated,” she said. “If it gets contaminated, it is a source of infection.”

How Many Eye Drops Should You Use?

More drops do not mean more relief.

“The capacity of the eye is only one drop,” Dr. Ritika said.

Putting two or three drops at once can cause the excess to spill onto the surrounding skin and simply waste the product. One properly administered drop is generally enough at a time, she said.

Avoid Squeezing Your Eyes After Using Drops

Dr. Ritika said people often squeeze their eyes tightly after putting in drops because they think this will keep the medicine inside. But squeezing can push the drop back out.

Instead:

• Gently pull down the lower eyelid.
• Place the drop into the eye.
• Avoid touching the bottle tip to the eye.
• Do not squeeze the eyes tightly immediately afterward.

Why Do Eye Drops Sometimes Reach The Throat?

Some people experience an unpleasant sensation in the throat after using medicated eye drops.

Dr. Ritika explained that tears can travel from the eye through the tear duct to the nose and then the throat.

She suggested gently pressing near the inner corner of the eye for a while after applying the drop to reduce this drainage.

Never Share Your Eye Drops

Sharing eye drops may seem harmless, particularly within families, but Dr. Ritika advised against it.

If the bottle tip accidentally touches an infected eye, the bottle can become contaminated and potentially transmit infection when used by someone else.

“Eye drop is something that is for your personal hygiene and it should therefore be kept by you and used by you,” she said.

Clear vision does not always mean that the eyes are healthy. Diabetes can damage the retina the sensitive layer at the back of the eye long before a person notices any change in eyesight.

This happens because high blood sugar can weaken the blood vessels that supply the retina causing them to leak fluid or blood.

What happens as retinopathy progresses?

Diabetic retinopathy is a complication in which high blood sugar damages the blood vessels. In the stages these vessels may swell or develop small areas of bleeding without affecting vision.

As the condition advances, reduced blood supply can cause abnormal new blood vessels to grow. These vessels are fragile. May bleed into the vitreous the clear gel inside the eye. In some cases, scar tissue can pull the retina away from its normal position leading to retinal detachment and potentially permanent vision loss.

How diabetes affects central vision

Diabetes can also affect the macula, the part of the retina responsible for sharp detailed vision. When fluid builds up in this area it can cause macular oedema and gradually affect the quality of vision.

It may lead to:

• Distorted central vision
• Difficulty reading or recognising faces
• Problems with activities that require clear detailed vision, such as driving

Diabetic macular oedema can occur at different stages of diabetic retinopathy and does not always cause symptoms in the early stages.

Who is at risk?

The likelihood of eye damage increases with the duration of diabetes and poor blood sugar control. High blood pressure, abnormal cholesterol levels and kidney disease can further increase the risk.

Women with diabetes may also need monitoring during pregnancy as hormonal and blood sugar changes can worsen existing retinal disease.

Why regular eye examinations matter

On World Sight Day, doctors recommend that a routine eyesight test may not detect damage to the retina. People with diabetes should therefore undergo an eye examination, including a dilated retinal examination at intervals recommended by their ophthalmologist.

Keeping blood sugar, blood pressure and cholesterol, under control can help reduce the risk of complications. If damage is detected treatment may include eye injections, laser therapy or surgery depending on its severity.

Diabetic eye disease can often be managed effectively when identified early. Regular retinal examinations remain important when a person can see clearly as changes may develop before symptoms appear.
