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.

While you may have seen multiple women, who are not pregnant, taking prenatal vitamins to improve their skin, hair and nail quality, experts say you should steer clear and only stick to multivitamins to ensure your body stays healthy all-year round.

Prenatal vitamins are daily supplements for women who are pregnant or trying to get pregnant. These supplements contain the vitamins and minerals you need to support healthy fetal development, according to the Cleveland Clinic.

Dr Rohan Palshetkar, Consultant IVF Specialist, Bloom IVF tells Healthandme: ""Prenatal vitamin should be taken three months at least prior to the pregnancy or basically whenever you begin to start planning the pregnancy, ensure that all your micro nutrients as well as your folic acid levels are up to the normal mark so as to ensure that your baby has a healthy growth"

But when your body doesn't need it, taking supplements could put you at risk over time.

Which Vitamins And Minerals Are Prenatal Vitamins Rich In?

As per the American College of Obstetricians and Gynecologists (ACOG), here are the most important nutrients prenatal vitamins are packed with:

Folic Acid: One of the most important prenatal nutrients, this B vitamin is important as it creates your baby's neural tube. This is the structure that eventually forms brain. As per the US Preventive Services Task Force, folic acid supplements significantly increase the growth of healthy neural tube. The American Academy of Pediatrics also notes that it helps the neural tube to protect from defects by 50 percent.

Iron: It supplies blood and oxygen to the fetus and also helps build the placenta. It also gives the mother extra blood volume that you need throughout pregnancy. Pregnant people are prone to anemia, this is why iron supplementation is a must.

Calcium: The most time spend in uterus for a baby is invested in building their bones and teeth, this is a Herculean task, and requires the mother to have plenty of calcium. If you don't have enough calcium, then your baby will utilise the calcium from your body, which could lead to temporary bone loss.

Certain prenatal supplements also contain other additives such as omega-3 fatty acids.

Why Is It Dangerous To Take Prenatal Vitamins

The main difference between a prenatal vitamin and a multivitamin is the concentration of folic acid and iron.

Ingesting enough folate from food or folic acid from supplements at the start of a pregnancy lowers the risk of certain birth defects. Along with this, iron supplements help the body make the extra blood cells needed during pregnancy.

The amount of folic acid suggested for people who are planning a pregnancy is 400 to 800 micrograms (mcg) a day. The amount of iron needed in pregnancy is 27 milligrams (mg) a day.

The typical amount of folic acid for an non-pregnant adult is 400 mcg a day. For iron, the typical daily amount is 8 mg for males and 18 mg for females.

Taking iron and folic acid at levels higher than the suggested amounts may bump people closer to the upper limit for these nutrients which can raise the risk of health problems.

Taking too much folic acid, especially over 1,000 mcg daily without a doctor's advice, can mask a vitamin B12 deficiency, potentially causing irreversible nerve damage and may lead to side effects such as bitter taste, nausea or sleep problems, with potential links to increased risks in pregnancy like autism or insulin resistance.

Eating too much iron, especially from supplements, can cause acute iron poisoning, leading to severe nausea, vomiting, abdominal pain, diarrhea and bloody stools. Long-term excessive intake causes iron to deposit in tissues, causing iron overload (hemochromatosis) that damages the liver (cirrhosis), heart (failure), and pancreas (diabetes) and may cause a bronze skin color.

The Olympic Games are often seen as the ultimate celebration of human endurance, discipline and perfection. But behind the glittering medals, roaring crowds and emotional national anthems lies a quieter, more personal struggle many athletes carry with them, their mental health.

As the 2026 Winter Olympics in Milano Cortina draw closer, officials from the United States Olympic & Paralympic Committee (USOPC) are acknowledging a reality that has long remained in the shadows. According to the organization’s chief medical officer, Jonathan Finnoff, nearly half of U.S. Olympic athletes and 60 percent of Paralympic athletes are expected to experience symptoms linked to mental health concerns while preparing for or competing in the Games. These numbers highlight how elite sports, despite its glamour, can place enormous emotional and psychological pressure on athletes.

The Growing Recognition Of Mental Health In Elite Sports

Over the years, conversations around athlete well-being have shifted significantly. Earlier, the focus remained heavily on physical fitness and performance, while emotional struggles were often dismissed as signs of weakness. Today, sports bodies are beginning to understand that mental fitness is just as important as physical conditioning.

In response, the USOPC has introduced a wide range of support systems. These include hiring specialized professionals trained in both mental health care and performance psychology, creating virtual consultation services, and introducing structured screening programmes to identify athletes who may require additional support. Officials claim that the programme has grown into a comprehensive support network designed to assist athletes before, during and after competitions.

However, these initiatives have not emerged without criticism. Reports and athlete testimonies over the years have pointed towards gaps in earlier mental health care systems within competitive sports. The issue gained global attention when several high-profile athletes openly spoke about their struggles.

Simone Biles And The Turning Point

One of the most defining moments in this conversation occurred during the Tokyo Olympics in 2021, when American gymnast Simone Biles withdrew from the individual all-around final after experiencing what gymnasts refer to as “the twisties”, a dangerous mental block that disrupts spatial awareness mid-performance.

Her decision sparked global debate and encouraged many athletes to speak openly about psychological challenges. Prominent sportspersons from different disciplines followed suit, helping dismantle long-standing stigma around mental health in professional sports.

Following these developments, the USOPC significantly expanded its psychological services, increasing the number of licensed professionals and strengthening its support infrastructure. Additional funding from private foundations further helped expand mental health resources available to athletes.

Life After The Spotlight: The Emotional Void Athletes Face

For many athletes, the psychological strain does not end with the competition. Olympic freestyle skier Nick Goepper has spoken openly about his personal struggles with depression, substance abuse and feelings of purposelessness after major sporting events.

Athletes often dedicate their entire lives to reaching the Olympic stage. Once the event concludes, many find themselves grappling with identity crises and emotional emptiness. The sudden transition from global recognition to everyday routine can be deeply unsettling, especially when athletes begin questioning their purpose beyond sport.

Mental health professionals working with Olympic teams now recognize that athletes are not only dealing with performance pressure but also navigating personal life challenges, grief, injuries and major life transitions during their careers.

Balancing Performance And Well-being

While global sponsors and sporting organizations continue to prioritize medal tallies, there is growing acknowledgement that long-term athletic success cannot be separated from mental well-being. Psychological services within Olympic teams now focus not only on improving performance but also on helping athletes manage stress, trauma and life challenges.

Experts working with Olympic teams note that mental health support often extends beyond competition preparation. Athletes may seek counselling for personal losses, relationship struggles or major life changes, all of which can affect performance and overall well-being.

A Cultural Shift In Sports

The evolving approach toward athlete mental health reflects a broader cultural change in competitive sports. Open conversations, improved medical support and athlete-led advocacy are slowly transforming how mental health is perceived in elite sporting environments.

As the Milano Cortina Games approach, the spotlight will undoubtedly remain on record-breaking performances and medal counts. Yet, an equally important story will unfold behind the scenes — one where athletes, coaches and sports organizations work together to ensure that champions are supported not just physically, but emotionally as well.

Non-alcoholic fatty liver disease, often called fatty liver, occurs when excess fat builds up in the liver due to reasons unrelated to alcohol consumption. Multiple studies suggest that nearly 35 to 40 percent of Indian adults may already be living with fatty liver disease. Experts believe this figure could be a conservative estimate, making it a growing public health concern.

What is even more worrying is that Indians are significantly more prone to developing fatty liver disease compared to many other ethnic groups.

A Genetic Link Rooted in Survival

Dr Alok Chopra, a cardiologist and functional medicine expert with over four decades of experience, recently explained in an Instagram video why Indians are disproportionately affected.

“This is not just about junk food or sitting all day,” Dr Chopra said. “People from the Indian subcontinent developed a survival mechanism over generations of famine. Our bodies learned to store fat quickly, especially in the liver, to protect us during periods of starvation.”

According to him, this genetic adaptation has outlived its usefulness in modern times. “The famine disappeared, but the genetic switch never turned off,” he explained. “That is why today nearly one in three Indians is estimated to have fatty liver disease, and the real number may actually be closer to half the population.”

Why Fatty Liver Often Goes Unnoticed

Fatty liver disease is often called a silent condition because it may not cause obvious symptoms in its early stages. Many people discover it accidentally during routine blood tests or ultrasound scans. If left unchecked, it can progress to liver inflammation, fibrosis, or even cirrhosis.

Dr Chopra warns that ignoring early signs can be risky, but he also offers reassurance.

The Liver Can Heal If Given the Right Support

“The good news is that fatty liver is one of the most reversible conditions,” he said. “The liver is a remarkable organ. It detoxifies, regenerates, and supports metabolism, hormones, and energy. But it needs the right environment to heal.”

According to him, early action through lifestyle and nutrition changes can make a significant difference before the disease progresses.

Three Simple Steps to Reverse Fatty Liver

Dr Chopra outlines three key strategies to support liver health.

First, he advises aligning eating habits with the body’s natural rhythms. “Eat your dinner early, avoid late-night snacking, and include periods of intermittent fasting,” he said. “This is how our ancestors naturally lived.”

Second, he stresses the importance of cooking fats. “Your grandmom was right,” he noted. “Use ghee instead of refined seed oils. Bad oils, corn syrups, and highly processed foods push the liver towards inflammation and fat storage.”

Lastly, he highlights antioxidants. “Glutathione is the body’s master antioxidant,” Dr Chopra explained. “You can also support it with berries, dark leafy greens like spinach and kale, colorful vegetables, and even coffee, which research shows can lower the risk of fatty liver.”

With awareness and timely action, fatty liver disease does not have to be permanent.
