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.

Bob Harris, the renowned BBC Radio 2 host, has informed his listeners of being hospitalized again for prostate cancer treatment.

Posting on social media platform Instagram, Harris said he is receiving treatment for an issue that has developed over the past few weeks.

“As many of you know, I suffer from prostate cancer, and every now and again I experience setbacks that need attention. Now is one of these moments,” he wrote, along with a picture of himself lying in a hospital bed while smiling for the camera.

Harris noted that he’s taking short break away from his programs. However, he confirmed that this week’s Country Show is scheduled as planned, and his Sounds of the 70’s episode on 12th April will feature an 80th birthday celebration special he recorded before attending the C2C Festival with Zoe Ball.

Noting that he can’t state the day of his return as the host, he said: “I know that I will come back… and come back stronger”.

“I hate missing programs and I am keen to get back into the studio as soon as I can”.

Calling himself “blessed” for the support he received from friends and family and listeners of his show, Harris said that during his absence, Darius Rucker will guest on Country, while Shaun Keaveny will cover Sounds of the 70’s for a few weeks.

"I am so blessed to have the love of my family and the support of my friends who have rallied round me at what has proved to be an unexpectedly testing time,” Harris said.

Prostate Cancer: The UK’s Most Common Male Cancer

Prostate cancer remains the most common cancer among men in the UK, with around 55,000 cases diagnosed every year. Despite this, there is currently no national screening program because of concerns over the accuracy of PSA tests.

In November 2025, former UK Prime Minister David Cameron revealed his prostate cancer diagnosis and also called for a targeted screening.

In an interview with Times, he said, "You always hope for the best. You have a high PSA score - that is probably nothing. You have an MRI scan with a few black marks on it. You think, ‘Ah, that’s probably OK.’ But when the biopsy comes back, and it says you have got prostate cancer. You always dread hearing those words. And then literally as they’re coming out of the doctor’s mouth you’re thinking, ‘Oh, no, he’s going to say it. He’s going to say it. Oh God, he said it.’"

The former PM, said that he had a prostate-specific antigen (PSA) test for the screening that looks for proteins associated with the form of the disease. His result was high, and a biopsy after that revealed his cancer.

In October 2024, six-time Olympic gold medallist Chris Hoy revealed he had been diagnosed with terminal stage 4 cancer. His prostate cancer had spread to his shoulder, pelvis, hips, ribs and spine.

A woman’s health check-up is not about being paranoid. It's about refusing to treat your body as an afterthought.

You may not be able to control every diagnosis you ever get. But you can control how late you meet it. That's what preventive care is all about. Early detection through these screenings helps manage hormonal changes, cancer risks, and metabolic health.

From routine blood tests to specialized screenings, Dr. Supriya Bali, Director, Internal Medicine, Max Super Speciality Hospital, Saket, spoke to HealthandMe on specific tests crucial for women, right from their 20s

In Your 20s: Laying A Strong Foundation

Your 20s are all about establishing healthy habits that will carry you through life. Even if you feel great, this is a crucial time to get in the habit of seeing your doctor regularly.

Recommended screening includes:

  • Blood pressure check – Every 1-2 years if normal; more often if elevated
  • Pap smear – Start at age 21 (or by age 25 if you’ve never been sexually active); every three years if results are normal
  • Chlamydia and gonorrhea screening – Annually for sexually active women under 25
  • HPV vaccine – If not already completed by 26
  • Skin check – Monitor moles and sun damage, especially if you tan easily
  • Mental health screening – Don’t ignore stress, anxiety, or depression

In Your 30s: Reproductive And Preventive Health In Focus

As the body begins to undergo subtle changes in the 30s, regular screenings, hormonal health checks, and lifestyle adjustments are increasingly important.

Recommended screenings in 30s include:

  • Pap + HPV co-test – Every 5 years starting at 30 (or Pap every 3 years)
  • STI screening – Based on risk factors and symptoms
  • Blood pressure and cholesterol check – Especially if you have a family history

This is a time when early signs of chronic conditions may start to show up, especially if there’s a family history of heart disease, diabetes, or cancer.

You should get these screenings at certain times:

  • Mammography screening: Begin at 40 years of age (earlier if you have a family history of breast cancer).
  • Pap smear & HPV test: Pap and HPV every 5 years or Pap alone every 3 years.
  • Cholesterol & Blood Pressure Testing: Every 1-2 years.
  • Blood glucose test (diabetes screening): especially if you're overweight or at risk for diabetes.
  • Thyroid function testing is optional—especially if you feel tired, cold, or have been losing weight or have changes in your bowel habits.
  • Weight discussions regarding healthy nutrition and active lifestyle—assist with maintaining a healthy weight.
  • Perimenopause begins in your 40's; if you experience mood swings or changes in sleep, hot flashes, or irregular cycles, please speak with your doctor.

Vaping Becomes Major Nicotine Threat Among Children Under 5 in US, Warns Study

Updated Apr 4, 2026 | 11:00 PM IST

SummaryResearchers from Rutgers University found that electronic cigarette-related incidents increased 243 percent over the past eight years in young children, especially among those under five years of age in the US.

Vapes were marketed as a safer option than cigarettes, but research now shows they carry serious health risks -- from lung damage to meningitis to cancer.

Vaping has been a serious concern in the United States, with New York Attorney General Letitia James in 2025 filing a lawsuit against e-cigarette manufacturers and distributors.

The lawsuit accused the companies of fueling a youth vaping crisis, alleging that these companies that manufacture vapes, especially with flavors, have misled consumers about the safety of their products while deliberately targeting young people through deceptive marketing.

Now, a new study, published in JAMA Network Open, has for the first time assessed trends in young children's nicotine exposures across all types of products.

Shockingly, electronic cigarette-related incidents increased 243 percent over the past eight years in young children, especially among those under five years of age, said researchers from the Rutgers New Jersey Medical School.

In contrast, tobacco exposures from conventional products such as cigarettes decreased by 43 percent.

Unlike cigarettes, these devices are often ready to use, brightly colored, require little effort to activate, and appear more like toys than a harmful product.

"This significant spike in children breathing in these substances tells us the risk has changed: It's no longer just about a toddler swallowing something they found on the floor," said lead author Perry Rosen, who conducted the research at the New Jersey Poison Control Center.

"Many recent cases involve children actively using e-cigarette devices after gaining access to them," Rosen added.

Key Findings

The findings were based on an analysis of more than 92,000 reported nicotine exposures in children ages 5 and younger between 2016 and 2023.

The researchers noted that vaping risks often involved children who inhaled the vapors directly from the devices. They also found that children exposed to e-cigarettes were more likely to require a visit to a health care facility compared with those exposed to cigarettes.

According to researchers, young children naturally mimic the behaviors they see around them. So, parents and caregivers must keep vaping devices away from the reach of young children.

Previous research has shown that even moderate ongoing nicotine exposure can lead to lasting health effects on developing lungs, including increased risk of bronchitis and worsening asthma.

"When children see caregivers or older family members vaping, they may copy that behavior—bringing the device to their mouth and inhaling—without any understanding they are exposing themselves to a harmful substance," said Diane Calello, executive and medical director of the New Jersey Poison Control Center.

Vaping: A Concern

Vaping has become a more common form of tobacco use among American middle and high school students.

As per the US Centers for Disease Control and Prevention (CDC), nearly 1.6 million students used e-cigarettes in 2024, with 87.6 percent of them opting for a flavored product.

It is the flavor that makes it even more addictive, and people want to keep smoking it, resulting in it being emptied and refilled way more quickly.

This means those who smoke flavored cigarettes consume more tobacco than those who smoke unflavored ones.
