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 view generally is that the occurrence of knee issues is usually associated with age, injury or overexertion. However, there is another reason people ignore: lack of movement. If a person leads an inactive lifestyle, spending long hours sitting at a desk, working from the couch, watching TV or doing nothing physical, the eventual consequences for the knees might arise.

Knees are created for motion, and motion is essential for keeping the flexibility of a joint. Their effective functioning depends on the health of the muscles surrounding your knee. The less active various leg muscles are, including quadriceps and other counterparts, the weaker they will be. The muscles help stabilize the knee and can relieve it from some of the burdens during daily activities performed by the knees.

Remaining seated for an extended time can also lead to stiffness. When you sit for a while, you may feel uncomfortable or stiff in your knees when you finally stand up. While the occasional instance of stiffness may go away with movement, constant stiffness can impact mobility and cause people to wish to move even less.

Another issue is gaining weight. Living a sedentary lifestyle causes individuals to become heavier, and excess weight puts more stress on the knees. In time, this added pressure will lead to increased wear of the joints and the development of knee pain and other problems in the musculoskeletal system.

The positive aspect with respect to your knees is that you don’t have to put in hours at the gym to keep them safe. Small, steady efforts can easily do the trick. You can choose to walk for five minutes after being seated for a long time, stretch regularly, take stairs if you are physically able and do some simple workouts for the legs and thighs to increase strength. Low-impact sports such as swimming, cycling and walking can help you maintain muscle power and flexible joints while avoiding the stress on your knees resulting from extensive workouts.

Persistent pain in the knee, however, cannot be treated as a usual symptom of ageing. Knee swelling or prolonged stiffness, difficulties climbing stairs, instability, or pain that has an impact on routine activities should be addressed by health professionals.

Movement is necessary for knees to be strong and flexible. Therefore, if you want your knees to be strong, you need to use them consistently and perform all activities without remaining still for long.

Blocked ears are one of the most common and irritating problems associated with air travel.

While the sensation usually resolves on its own shortly after landing, for 22-year-old Aida Burkins from California, it persisted and eventually led to a frightening diagnosis of rare head and neck cancer.

Blocked Ears Persisted After Flight

Burkins was travelling to Chicago in May 2025 when her ears became blocked. When she returned home, her ears still hadn’t popped.

She later developed unusual symptoms, including hearing loss and bleeding from her throat.

“I started bleeding into my throat, which would only come out of my nose if I was bent at the hip at about 90 degrees,” the 22-year-old told Newsweek. “My hearing got worse and worse. Then I started getting more tired and losing weight.”

Symptoms Were Initially Dismissed

When Burkins sought medical help, her condition was initially dismissed as “just altitude sickness.” After several months, her hearing had deteriorated significantly.

“Everything sounded so muffled, and I had a ringing that wouldn’t go away,” she said.

Burkins eventually saw an ear, nose, and throat (ENT) specialist, who discovered a mass and noted that her adenoids — soft tissue in the throat, just behind the nose — were inflamed.

“The doctor told me he had never seen anything quite like what I had going on. He couldn’t be sure it was cancer, but he said it was very suspicious,” she told the outlet.

Diagnosed With Rare Head And Neck Cancer

In February 2026, after undergoing CT scans and two biopsies, Burkins learned that she had a widespread tumour affecting the cervical lymph nodes near the base of her skull.

She was diagnosed with nasopharyngeal carcinoma, a rare type of head and neck cancer that starts in the upper part of the throat behind the nose and near the base of the skull, according to the American Cancer Society.

“Hearing I have cancer, all I thought about was not being able to see my babies grow up or do the things they want to do in life. It was horrifying,” Burkins, who is a mother to a 1-year-old and 3-year-old.

Burkins has since undergone months of chemotherapy and radiation. She is now finishing her treatment and hopes to be cancer-free soon as her body is responding well to the treatments.

What Is Nasopharyngeal Carcinoma?

According to the Mayo Clinic, nasopharyngeal carcinoma is a cancer that starts as a growth of cells in the nasopharynx, the upper part of the throat located behind the nose.

The cancer is rare in the United States and occurs much more often in other parts of the world, particularly Southeast Asia.

Nasopharyngeal carcinoma can be difficult to detect early because the nasopharynx is not easy to examine and there may be no symptoms initially.

Symptoms To Watch For

When symptoms do occur, they present non-classic signs which include:

• A lump in the neck caused by a swollen lymph node
• Nosebleeds
• Bloody saliva
• Double vision
• Ear infections
• Facial numbness
• Headaches
• Hearing loss
• Nasal stuffiness
• Ringing in the ears, known as tinnitus
• Sore throat

How Is It Treated?

Treatment for nasopharyngeal carcinoma usually involves radiation therapy, chemotherapy, or a combination of the two, depending on the cancer and the individual patient.

Perimenopause has become a regular conversation and its been high time that people are talking about it. You can see friends discussing it, social media coverage has increased and more importantly women are discussing this with their gynaecologists.

For decades, menopause was thought to be a single event - that is the day the periods stopped, but today we understand that the transition lasts for a few years. These changes can affect the quality of a woman’s life and hence I’m glad the conversation has gained more traction.

Perimenopause-Related Changes

First lets understand what perimenopause is. It literally means “around menopause” Its a transition phase where the ovaries gradually change the production of the hormones, mainly oestrogen and progesterone. It usually begins in the early 40’s but some women may experience it earlier.

One of the commonest signs of this is a change in the pattern of your menstrual cycle. Periods can be become longer or shorter, heavier or lighter. Basically the menstrual cycle becomes a bit unpredictable.

But periods aren’t the only sign. A woman may start experiencing disturbed sleep cycles. She may wake up randomly at 3am or feel exhausted despite getting 7-8 hours of sleep. Hot flushes and night sweats may also occur. Mood changes, irritability, anxiety and difficulty in concentration can also affect her quality of life.

Some women complain of being forgetful or more commonly used term "experience brain fog”. They forget names, lose train of though or struggle to multitask. There can also be a change in libido, vaginal dryness, discomfort during intercourse, headaches, join pain and alterations in skin and hair.

Besides this there could possibly a change in the body composition. A woman may notice increasing abdominal fat or find difficulty in maintaining her weight even though her lifestyle hasn’t changed.

Why The Current Focus On Wellness Is Important?

The good part of this increase in awareness is that women are paying more attention to their health early rather than waiting of menopause. This transition phase provides a golden opportunity to reassess exercise, nutrition, sleep and preventative healthcare.

Strength training becomes even more valuable as it helps maintain muscle and bone mass.

Adequate protein, calcium and Vitamin D intake along with a balanced diet helps long term metabolic and bone health.

During this time, its important for a woman to even assess her cardiovascular health. Blood pressure, cholesterol, blood sugar and weight don’t just become numbers on the chart anymore, they become important markers of future health during this time.

Not Every Symptom Should Be Blamed On Hormones

However every label shouldn’t be blamed on perimenopause. Thyroid disorders, anaemia, vitamin deficiencies, depression and few other medical conditions can produce similar symptoms.

Unusually heavy bleeding, bleeding between periods or after intercourse also warrants medical assessment rather than being dismissed as “just hormones”.
