One must be very careful about what they consume. One of the easiest ways to get sick is by eating food or having beverages from unsafe and unsanitary places. That is why people are discouraged from eating at roadside stalls or food from street hawkers who do not follow the food safety protocol. Many people do not know how unsafe tap water can be. While the tap water available at home goes through treatment, it is best to only drink it after boiling or opting for water from the filter. The Centers for Disease Control and Prevention (CDC) explains that these health issues can range from mild to serious, depending on what germs are being transmitted. In a TikTok, Doctor Suraj Kukadia who goes by Dr. Sooj, a practicing NHS GP and emergency doctor, issued a critical warning. urgent warning that if you use regular tap water to rinse your nose, you could be exposed to a very rare but dangerous "brain-eating amoeba." Even though tap water in the UK is perfectly safe to drink, it's a different story when it comes to cleaning out your nose. Why Tap Water Is Risky for Your Nose Rinsing your nose is a common thing people do when they have a cold, allergies, or a sinus infection. You usually flush water or salt water into your nose to wash away snot, dust, pollen, and anything else that might be irritating your nasal passages. But in a video, a doctor known online as Dr. Sooj, explained why tap water is risky for this. He said that "tap water has bacteria. It has amoeba, it has protozoa. There are tiny living things in the water." When you drink these, your stomach acid usually kills them, but when they go up your nose, it's a different story. Brain-Eating Amoeba The main worry is a "brain-eating amoeba" called Naegleria fowleri. This tiny creature loves to live in warm fresh water, like lakes, rivers, and hot springs. The Cleveland Clinic explains water that contains this amoeba goes up your nose, it can travel to your brain. Once there, it causes a very serious and almost always deadly infection called Primary Amebic Meningoencephalitis (PAM). While this infection is rare, it's not worth the risk. If the amoeba gets into the brain through the nose, it can cause a severe infection called Primary Amebic Meningoencephalitis (PAM). Early signs of PAM can be a headache, fever, feeling sick to your stomach (nausea), and throwing up (vomiting). This infection moves incredibly fast. Most people who get PAM unfortunately die within just 1 to 18 days after they start showing symptoms, often falling into a coma before death. Other symptoms can include a stiff neck, feeling confused, not paying attention to people around you, losing your balance, and seeing things that aren't real (hallucinations). When to Seek Medical Help Health experts like the Centres for Disease Control and Prevention (CDC) agree with this advice. They also warn about another amoeba called Acanthamoeba. If you or someone you know starts to have a headache, fever, confusion, or vomiting soon after rinsing your sinuses or nasal passages, it's crucial to get medical help right away.
