Mosquitoes are a big part of the ecosystem, but often are a nuisance as they bite and feed off of us. Their bites cause itchy red bumps and spread infections and allergies in our bodies. But have you ever wondered why they bite certain people more than others? While some people are plagued by mosquito bites, others barely notice them. Here are some interesting facts about mosquitoes that you must know about!

1. Carbon Dioxide:

Mosquitoes are attracted to a certain smell that emits from the human body that is present in the human skin and sweat, mosquitoes can sense the carbon dioxide or CO2 we breathe out. The more active you are, the more CO2 you emit and the more mosquitoes will be attracted to you. Researchers are still investigating the cause of the variation of body odour that brings them to you, possibly genetics or certain bacteria. The unique combination of sweat and skin bacteria creates a scent that mosquitoes find irresistible. Some chemicals in sweat, like lactic acid and ammonia, are especially attractive to them.

2. Colours

While the reason isn't fully understood, mosquitoes seem to be drawn to dark colours like black more than lighter ones. So, ditch the dark outfit next time you're in mosquito territory. It has been noted that mosquitoes are more likely to leave lighter colours alone.

3. Heat and Vapour

Mosquitoes can detect your body's heat and water vapour, acting like a beacon guiding them right to you. So next time you're feeling sweaty, be aware you might be attracting a lot of mosquitoes. If you are working out or doing something that is making you sweat and your body heat rise, the mosquitoes nearby will be instantly attracted to you. Even mosquitoes are careful about who they pick as a host, some studies even suggest that they like a certain body temperature to feed off of.

An interesting fact about mosquitoes is that they can learn to like a host. They have their own preferences and if they meet a certain person who fits their criteria they might be the next host they move onto. In an older study, it showed that 20 per cent of people with mosquito-borne diseases accounted for 80 per cent of diseases transmitted in the population. They suggest that they only bite a certain set of people within the population.

4. Other factors:

Studies suggest mosquitoes might learn to prefer certain people based on things like what you've been drinking. In a 2002 study, there could be many reasons they like alcohol to making your body temperature high etc. Even pregnant women seem to be extra attractive to them due to higher body temperature and CO2 output.

The southern Indian state of Karnataka, currently reeling under intense summer heat, has been experiencing an outbreak of viral gastroenteritis over the past few weeks, according to media reports.

Due to the scorching heat, doctors in Mysuru flagged a 15-20 per cent rise in patients with gastrointestinal complaints, Deccan Herald reported.

According to Dr A. K. Satheesh Rao, senior consultant in medical gastroenterology and hepatology, the early arrival of summer with higher intensity across Mysuru and surrounding regions is driving the cases.

“The prolonged spells of heat and rising temperatures are impacting stomach and digestive health. Over the past few weeks, we have seen about a 15-20 per cent increase in patients with gastrointestinal complaints like frequent episodes of vomiting, abdominal discomfort, rapid dehydration, and diarrhea. Another major concern is a rise in dehydration,” he said.

“Although such seasonal spikes are expected, this year the intensity and frequency of symptoms are concerning, as a majority of the cases are being diagnosed as viral gastroenteritis. Just like any other viral infection, viral gastroenteritis is transmissible through contaminated food and water,” Dr. Rao added.

Meanwhile, the India Meteorological Department (IMD) has issued a warning of rising heat and humidity across Coastal Karnataka until April 12.

Districts like Dakshina Kannada, Udupi, and Uttara Kannada are expected to experience hot weather with high atmospheric moisture. Such weather can lead to fatigue and discomfort, particularly among the elderly, children, and those with existing health conditions.

The IMD has advised people to stay well hydrated and take precautions while stepping outdoors. Residents are also urged to avoid prolonged exposure to the sun during peak hours.

What Is Gastroenteritis?

Commonly referred to as the stomach flu, gastroenteritis is another illness that tends to spike in the fall.

Caused by viruses like norovirus, this condition leads to inflammation of the stomach and intestines. While gastroenteritis is typically short-lived, it can be particularly uncomfortable and disruptive.

Common symptoms include:

• Nausea and vomiting – More common in children than adults.
• Watery diarrhea – May cause dehydration if not well taken care of.
• Stomach cramps and pain – Usually intense and sudden.
• Mild fever and body aches – May be confused with flu.
• Sudden development of illness – Symptoms develop 24-48 hours after exposure and persist 1-3 days.

Gastroenteritis can affect children more intensely. Dehydration is the most immediate threat posed by stomach flu, particularly among infants and young children. As children quickly lose fluids from diarrhea and vomiting, parents must observe warning symptoms of severe dehydration, such as:

• Dry mouth and tongue
• Decreased urine output (fewer wet diapers in an infant)
• Not crying tears
• Sunken soft spot on the top of a baby's head (fontanelle)
• Irritability, drowsiness, or lethargy.

How To Prevent

Hydrating oneself with portable water, eating healthy food, and maintaining hand hygiene are important.

“Simple practices like proper water storage, drinking filtered or boiled and cooled water, opting for home-cooked and freshly prepared meals, and basic hand hygiene serve as powerful safeguards,” Dr Rao said.

Further, one should also follow essential hygiene practices, including:

1. Practice frequent handwashing

2. Clean high-touch surfaces

3. Safe food handling

4. Keep sick children at home.

A Cancer-hit US couple in North Dakota has shared their ‘nightmare’ experience with dual diagnosis of the deadly disease and parenting their three children.

Spencer Eddy, a 39-year-old father of three, suffered from dizzy spells for years. While doctors dismissed the condition as vertigo, it turned out to be a brain tumor, People reported.

MRI scans in April 2024 revealed that he had a tumor the size of a lime in his brain. Further scans and tests at Mayo Clinic in October confirmed medulloblastoma -- a malignant tumor that is located on the part of the brain that controls coordination and movement.

According to the Mayo Clinic, it is most common in children, but can occur in adults.

“When we found out that Spencer had a brain tumor, we were terrified,” said Jolene, his wife. “They said the cancer was blocking the fluid that flows from your vein to your spinal cord. They said they didn't know how he was still walking and talking, and how he hadn't had a stroke."

A week later, Spencer underwent a 10-hour surgery, and doctors were able to remove 85 percent of the tumor. Along with radiation and chemotherapy, he also needed speech and physical therapy to relearn how to walk and talk, People reported.

What came as a double blow to the couple was Jolene’s breast cancer diagnosis in April 2025.

“Whilst we were in the hospital, I noticed a small pea-sized lump under my armpit, but I put it to the back of my mind, because of everything that was going on with Spencer,” she recalled. “Doctors said it was probably just a cyst, but I asked for it to be removed anyway, and when it came back from testing, I found out it was breast cancer. I was absolutely floored.”

The doting parents “were so devastated and scared about what would happen to their kids”, if both of them die.

Following her diagnosis, Jolene was given hormone blockers and underwent a double mastectomy while Spencer was still undergoing chemotherapy.

Jolene struggled after the surgery and was vomiting and passing out frequently. She ultimately needed a blood transfusion and was able to recover.

It was hard for Jolene to take care of the family as Spencer could not walk well or drive.

"We're living most people's nightmare, but we're feeling optimistic about the future,” she said. “We have a long life, and we're going to fight for it; we're not going to give up.”

Spencer completed treatment in April 2025 and now has no evidence of cancer. Jolene also has no evidence of cancer. The couple now goes to appointments with their oncologists together as they hope to ensure their tumors don't grow back, the report said

Can A Brain Tumor Cause Dizziness?

While dizziness by itself is not a common symptom of a brain tumor, some tumors can trigger headaches and bouts of nausea and vomiting that may be associated with a dizzy feeling.

Dizziness, also called vertigo, is however, associated with tumors that develop in the cerebellum—the part of the brain that controls movement.

Medulloblastoma, a type of brain tumor, forms when cells in the cerebellum develop changes in their DNA. These changes cause the cells to grow and multiply quickly, as per the Mayo Clinic.

Common signs and symptoms of medulloblastoma may include:

• Dizziness.
• Double vision or other vision changes.
• Headaches, which are often worse in the morning.
• Nausea or vomiting.
• Poor coordination.
• Tiredness.
• Difficulty with balance or an unsteady walk.

There are many myths linked to heart health that can mislead people and prevent them from seeking timely help. This article helps to debunk the myths and keep the heart healthy. It is time to prioritize heart health. Dr Rahul Gupta, Director of Interventional Cardiology and Structural Heart Program, Gleneagles Hospital, Parel, Mumbai, spoke about the common myths about heart disease and listed the facts as well.

Heart problems are commonly seen in people of all age groups. However, heart health is often surrounded by myths and misconceptions that can lead to confusion and poor lifestyle choices in people. So, heart health depends on multiple factors, including diet, activity, stress, and overall lifestyle, and not just one or two habits. Here, the expert helps to debunk the myths associated with heart health and improve the quality of life.

Dispelling myths surrounding heart health

Myth 1: Only older people are at risk of heart problems

Fact: People commonly believe that heart problems can only happen in old age. However, currently, a large number of youngsters aged 25-35 are also struggling with heart issues such as heart attacks and heart failure because of stress, unhealthy diets, and lack of exercise. So, heart problems are not limited only to older people. Anyone, irrespective of their age, can suffer from them. Hence, there is a need of the hour to go for regular heart check-ups and to initiate timely treatment for heart problems.

Myth 2: If you are fit, your heart is SAFE

Fact: So, being physically active is important, but it does not reduce the chances of heart problems. Be attentive to the family history, genetics, and other factors such as high cholesterol or even stress. So, go for cardiac screening on a yearly basis to know the status of your heart health. Discomfort in the arms, jaw, or back and light-headedness can also mean that your heart is in danger.

Myth 3: Heart disease is only seen in men

Fact: Shockingly, heart disease also causes higher morbidity and mortality rates in women. The symptoms seen in women linked to heart disease are dizziness, palpitations, and even giddiness. Hence, women should also focus on their heart health. Stay alert, stay safe!

Your heart health matters. By understanding the facts and making informed choices, it is possible for everyone to protect their heart and overall well-being.
