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.

People with hemophilia face an increased risk of poor bone health due to recurrent joint and muscle bleeds, joint damage and reduced physical activity. Experts told HealthandMe that preventing bleeds from childhood, alongside adequate nutrition, appropriate exercise and regular assessment, can help protect bone health throughout life.

Globally, an estimated 836,000 people have hemophilia, including approximately 284,000 with severe hemophilia. In India, the World Federation of Hemophilia (WFH) reported nearly 28,000 diagnosed and registered patients as of 2026, including more than 24,000 with Hemophilia A. However, the estimated prevalence could be as high as 1,36,000, suggesting many cases remain undiagnosed or misdiagnosed.

Childhood and adolescence are critical for building peak bone mass, making early intervention important for long-term musculoskeletal health, said health experts.

How Hemophilia Can Affect Bone Health

Hemophilia is an inherited bleeding disorder caused by a deficiency of clotting factor VIII (Hemophilia A) or factor IX (Hemophilia B). It primarily affects males, while women are often carriers.

Repeated bleeding into joints can cause chronic pain, joint damage, deformity and reduced mobility. Muscle bleeds can further restrict movement, limiting participation in physical activities that help maintain bone strength.

“Bone health begins in childhood, but protecting it is a lifelong commitment. In people living with hemophilia, recurrent joint and muscle bleeds, reduced physical activity and other risk factors can contribute to poor bone health and an increased risk of osteoporosis,” Dr. Varun Bafna, associate professor in the Department of Hematology at Chhatrapati Shahu Maharaj Government Medical College, Kolhapur, told HealthandMe.

Why Prophylaxis Matters

Prophylaxis involves preventive treatment to reduce bleeding episodes rather than treating bleeds only after they occur. Regular factor prophylaxis can help prevent recurrent joint bleeds, preserve joint function and support mobility.

“Regular factor prophylaxis helps prevent repeated joint bleeds and preserve joint function. That protection can support mobility, an important contributor to bone health,” Dr. Hitha B, associate professor and haematologist in the Department of Medicine at Government Medical College, Kozhikode, told HealthandMe.

She advised patients to discuss breakthrough bleeding or difficulties accessing treatment with their healthcare team so their treatment plan can be reviewed.

Dr. Bafna said consistent prophylaxis can also support muscle strength and safer participation in physical activity.

“Prophylaxis is not just about preventing bleeding today; it is an important part of protecting long-term musculoskeletal health and quality of life at every age,” he noted.

How to Protect Bone Health From Childhood

Experts recommend an individualized approach based on age, joint health, mobility and other risk factors. Key measures include:

• Calcium and vitamin D: Ensure adequate intake through diet and discuss supplementation with a healthcare professional when needed.
• Appropriate physical activity: Weight-bearing exercises suited to individual joint health can help maintain bone strength, with guidance from the care team.
• Physiotherapy: Tailored rehabilitation can help maintain muscle strength, mobility and joint function.
• Regular assessment: Periodic evaluation can identify bone-health concerns and determine whether further investigations are needed.
• Consistent prophylaxis: Adhering to prescribed preventive treatment can reduce bleeding episodes and help protect joints.

A Multidisciplinary Approach to Lifelong Care

Hematologists, physiotherapists and other healthcare professionals can help patients and families integrate preventive treatment, rehabilitation, nutrition and appropriate physical activity into an individualized care plan.

Early intervention and consistent care can help preserve joint function, mobility and quality of life as people with hemophilia grow older.

A stroke rarely announces itself loudly. A sudden wobble, a blurry eye or a slightly lopsided smile is easy to ignore. But in a stroke, minutes decide how much of the brain survives.

On World Stroke Day, doctors want everyone to know one simple tool: BE FAST.

What Doctors Say

Dr. Abhinav Gupta, Director of Neurology at Sarvodaya Hospital, Greater Noida West, and Dr. Atampreet Singh, Senior Director and Head of the Institute of Neurosciences at ShardaCare, Healthcity, told HealthandMe, “Knowing the early warning signs of a stroke can shorten the road to full recovery,” they said.

The problem, they added, is that “a stroke’s symptoms can be easy to dismiss as minor inconveniences, like being tired or having weak muscles.”

What Is BE FAST?

BE FAST was developed by Intermountain Healthcare as an adaptation of the American Stroke Association’s FAST model, according to a Frederick Health handout. The doctors break it down like this:

• B – Balance: “Unsteady feeling or sudden lack of muscle control and dizziness can be a warning sign of a stroke.”
• E – Eyes: “Don’t overlook loss of sight in one or both of a person’s eyes, sudden blurring, or double vision.”
• F – Face: “Ask the person to smile. Unevenness or droopiness on one side of the face can be a sign.”
• A – Arms: “Have the person raise both of their arms. If the person has difficulty holding one arm up or has unusual arm weakness, get emergency help.”
• S – Speech: “Sudden lack of ability to talk, inability to understand what others are saying, or slurred words, can be signs of a stroke.”
• T – Time: “If one of these symptoms occur out of the blue, then call emergency services. When the emergency operators are on the line, let them know what symptoms have presented.”

Why “Time” Matters The Most

Time is not a symptom. It is a reminder to hurry. Duke Health, citing the American Stroke Association, says to call for help even if the symptoms go away. Weill Cornell Medicine, citing the same group, says never to drive yourself to hospital.

The Frederick Health handout adds that you should note when the symptoms began. UChicago Medicine estimates that about 1.9 million brain cells die every minute in a stroke caused by a large blocked artery.

India’s biggest problem is delay in seeking medical treatment.

An ICMR study of 34,792 stroke cases at 30 hospitals between 2020 and 2022 found that only 5.3% of patients reached hospital within the first hour, according to South First. Nearly four in ten waited more than 24 hours. Down To Earth, reporting on a Lancet Neurology study, says India had over 1.25 million new stroke cases in 2021, up 51% since 1990.

If you see even one sign, don’t wait for the others. Call 112, India’s single emergency number, which also covers the 108 ambulance service, according to Factly. Say what you see and when it began.

Many people track their steps, sleep and heart rate with a precision that once seemed unusual. The feet behind those steps rarely get the same attention, hidden as they are inside shoes all day.

A crack, an ache or a patch of numbness is easily put down to the weather, age or an ill-fitting pair of sandals. Yet some complaints reach a clinic only after they begin to interfere with everyday life.

Symptoms That Are Easy to Explain

Cracked heels are a good example, because they are so common that most people treat them as a cosmetic matter and reach for a moisturiser. That is usually reasonable, although a deep fissure that bleeds or keeps reopening gives bacteria a way into the skin and is worth having examined.

Heel pain often has a musculoskeletal cause and tends to respond to rest and supportive footwear, but pain that lingers for weeks points to something more specific. Numbness gives the least warning of all, since it can arise from nerve compression, poor circulation, nutritional deficiencies or diabetes, and because it does not hurt, an injury can go unnoticed for days.

Why Weekly Measurement Matters

When a wound does develop, understanding whether it is actually healing becomes just as important as recognising the early warning signs. Researchers who monitor wounds over time know that appearance alone does not always tell the full story.

What a Recent Case Report Showed

A 2025 case report in the Journal of the Foot & Ankle followed two adults with long-standing diabetes and neuropathic plantar ulcers for twelve weeks, with wound area quantified by digital planimetry. One wound, treated with a graft of decellularised human dermis, shrank by 80 percent by week four and had fully epithelialised by week eight.

The other, managed with gauze-based moist wound care, reduced by 7.8 percent at week two, grew by 21.6 percent between weeks three and five, and reached a 68.6 percent reduction by week twelve without closing. No adverse events were recorded in either patient during the twelve weeks.

Reading the Evidence Carefully

The report is descriptive, and two patients cannot settle questions about any treatment. The lesson that carries beyond the clinic is more modest, since progress is easier to judge when it is tracked against a timeline.

Asking How Long, Not How Bad

For readers, the message is to pay attention not just to how serious a symptom looks, but also to how long it has lasted and whether it is changing. Cracks that repeatedly reopen, persistent heel pain and spreading numbness deserve medical attention.

For people with diabetes, any new foot wound should be assessed promptly rather than waiting to see whether it improves on its own.
