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.

When it comes to heatwave-like conditions, most people worry about the risk of dehydration and sunburn. But it turns out that the scorching heat could also take a toll on your skin—according to experts, extreme summer heat can increase the risk of skin infections. Heatwave-related skin infections can be triggered by high humidity, sweat, and bacteria trapped on the skin. Some of the other issues associated with heatwaves are folliculitis, heat rash, impetigo, and yeast infections.

What makes heatwaves conducive to increased skin infections?

Talking about it, Dr. Gitika Sanodia, Consultant Dermatologist at Dr. L H Hiranandani Hospital, Powai, answered some FAQs associated with heatwaves and consequent skin infections.

The expert said that when there is an increase in temperature, there is an increase in sweating, dehydration, and breakdown of the skin barrier, which creates an environment suitable for infection development, mainly in children, the elderly, diabetics, and obese individuals. Heatwaves also cause friction, which leads to skin infections. As a result, rashes can develop and cause a great deal of discomfort.

Can sweating too much increase the risk of infection?

During summer, because of the heat, one ends up sweating far more than normal, and if you are someone who often wears tight clothes, it can be even worse. Overproduction of sweat keeps the skin constantly wet. Such an environment provides perfect conditions for bacteria and fungi to multiply. Being trapped under breast tissue, between the thighs, and in folds around the neck and armpits causes conditions such as yeast infections or folliculitis.

What are the infections associated with heat?

During a heatwave, some skin infections are likely to develop silently. These include:

1. Fungal infections such as tinea and candidiasis
2. Bacterial infections such as folliculitis and boils
3. Heat rash resulting in miliaria

Who is at risk of skin infections during a heatwave?

At a time when temperatures are rising constantly, heatwave-related infections are likely to affect certain groups more than others. These high-risk groups are:

1. Children
2. The elderly
3. Overweight people
4. People with diabetes
5. People who wear tight or non-porous clothes during summer

How to prevent heatwave-related skin infections?

In order to prevent heatwave-related skin infections, you need not make major changes to your lifestyle or wardrobe. Rather, some simple, cost-free methods can also do the trick. Here are some expert-recommended tips to beat the heat:

1. Keep your skin dry, especially skin folds
2. Wear loose-fitting cotton clothes
3. Bathe after sweating
4. Do not share towels or undergarments with anyone
5. Use an antifungal dusting powder on susceptible areas
6. Keep yourself hydrated

With the increasing number of heatwaves, these problems have become more than just seasonal. However, with the right choices in terms of diet, lifestyle, and clothing, you may be able to avoid skin infections during a heatwave.

Persistent back pain in young adults is often dismissed as poor posture, long hours at a desk, or muscle strain. But doctors are warning that in some cases, it could be a sign of ankylosing spondylitis — a chronic inflammatory autoimmune disease that affects the spine and can silently progress for years before diagnosis.

In India, 16.5 lakh people suffer from the condition, with an average diagnostic gap of nearly seven years from the time symptoms first appear. During that window, the disease continues to silently progress, and the burden is far from small.

“Ankylosing Spondylitis is one of the most underdiagnosed conditions we encounter in clinical practice, and the consequences of that delay are real,” Dr. Arvind Mehra, Senior Director and HOD - Orthopaedics at Paras Health Gurugram, told HealthandMe.

Moreover, “It takes several years of pain and stiffness before people seek treatment, and by then, the diagnosis comes too late, and there has already been damage to the spine,” added Dr. Ashish Tomar, Director - Orthopaedics & Minimally Invasive Spine Surgery at Sarvodaya Hospital, Faridabad.

What Is Ankylosing Spondylitis?

Ankylosing spondylitis, also known as axial spondyloarthritis, is a type of arthritis that primarily targets the spine but can also affect other joints. The term “ankylosing” means stiff or rigid, “spondyl” refers to the spine, and “itis” indicates inflammation.

The inflammatory disease causes some of the bones in the spine to fuse over time. This fusing not only makes the spine less flexible but can also cause issues while breathing.

Ankylosing spondylitis leads to inflammation in the spine and large joints, causing stiffness and pain. It can also impact the joint between the spine and the hipbone, potentially resulting in additional symptoms such as digestive issues, rashes, and weight loss.

Not Your Typical Back Pain

What makes ankylosing spondylitis difficult to spot is that it often feels like ordinary back pain — but there are warning signs that set it apart.

According to experts, ankylosing spondylitis-related pain typically:

• Causes maximum stiffness early in the morning
• Gets worse after long periods of rest
• Improves with physical activity or exercise
• Persists for months rather than days or weeks
• Often begins in young adults, especially in their 20s and 30s

This pattern is very different from mechanical back pain, which usually worsens with movement and improves with rest.

Pain Beyond The Spine

Dr. Tomar told HealthandMe that ankylosing spondylitis is not simply a musculoskeletal problem — it is an autoimmune disease, where the body’s immune system mistakenly attacks healthy tissues, particularly around the spine and joints.

“Ankylosing spondylitis is not just another musculoskeletal disease. It requires the attention given to autoimmune disorders because it may affect the chest, hips, shoulders, and even the eyes, while also causing severe posture problems in advanced stages,” he said.

Beyond the spine, the disease may affect:

• Chest joints
• Hip joints
• Shoulders
• Eyes
• Posture, causing severe problems in the advanced stages

Who Is At Most Risk? How To Treat?

Young adults, typically in their twenties, are more likely to experience this condition because people often overlook its existence or mistakenly identify it as something else.

The combination of early diagnosis, structured physiotherapy, and suitable medications allows for effective disease progression control.

“When a young adult presents with inflammatory back pain, especially in the gluteal area, that persists beyond three months, the reflex should not be to prescribe a painkiller and wait. It should be investigated further. That shift in approach can make an extraordinary difference to someone’s long-term quality of life,” Dr. Tomar said.

Common treatments for ankylosing spondylitis include:

• Regular physical activity can reduce stiffness and prevent worsening of ankylosing spondylitis
• Over-the-counter painkillers for pain and inflammation
• Biologic DMARDs to reduce inflammation and pain, potentially halting disease progression.
• Corticosteroids are prescription anti-inflammatory medications
• Surgery is rarely suggested for severe symptoms unresponsive to other treatments.

When women are in their 40s, their bodies start to change a lot because of the hormones. This is mainly because the estrogen and progesterone levels in the body start to go down. This time is called Perimenopause.

It is when women start to move towards menopause. It can bring a lot of emotional changes. Some of these changes are normal.

Why Do Hormonal Changes Happen After 40?

After 40, women's bodies start to produce estrogen. This means they can have an imbalance.

Women's bodies need hormones like estrogen and progesterone to have periods, strong bones, a good mood, and to stay at a healthy weight. When these hormone levels change, it affects parts of the body. This change can take a year before it stops at menopause.

Common hormonal changes women experience

• Irregular periods

• Hot flashes and night sweats

• Mood swings and anxiety

• Weight gain and slower metabolism

• Sleep disturbances

• Skin and hair changes

Symptoms That Should NOT Be Ignored

While some changes are normal, some symptoms need a doctor's help:

• Heavy or prolonged bleeding

• Persistent fatigue

• Severe mood changes

• Sudden weight gain

• Bone pain or weakness

When women are over 40 and their hormones change, they are more likely to have:

• Heart disease
• Osteoporosis
• Thyroid disorders
• Metabolic issues

Estrogen helps keep the heart and bones healthy, so when its levels go down, women are more likely to have these health problems."

How Can Women Manage These Changes?

• Eat a balanced diet

• Exercise regularly

• Manage stress

• Have regular health check-ups

• Sleep well

Women should talk about these changes openly. If they know what is happening and see a doctor early, they can make this time easier.

Hormonal changes after 40 are a part of getting older, but women should not ignore them. Especially if the symptoms are very bad or happen all the time.

If women understand what is happening in their bodies and see a doctor when they need to, they can be healthier and more confident. If women take care of themselves now, they can have a life in the years to come.
