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.

There are many myths linked to heart health that can mislead people and prevent them from seeking timely help. This article helps to debunk the myths and keep the heart healthy. It is time to prioritize heart health. Dr Rahul Gupta, Director of Interventional Cardiology and Structural Heart Program, Gleneagles Hospital, Parel, Mumbai, spoke about the common myths about heart disease and listed the facts as well.

Heart problems are commonly seen in people of all age groups. However, heart health is often surrounded by myths and misconceptions that can lead to confusion and poor lifestyle choices in people. So, heart health depends on multiple factors, including diet, activity, stress, and overall lifestyle, and not just one or two habits. Here, the expert helps to debunk the myths associated with heart health and improve the quality of life.

Dispelling myths surrounding heart health

Myth 1: Only older people are at risk of heart problems

Fact: People commonly believe that heart problems can only happen in old age. However, currently, a large number of youngsters aged 25-35 are also struggling with heart issues such as heart attacks and heart failure because of stress, unhealthy diets, and lack of exercise. So, heart problems are not limited only to older people. Anyone, irrespective of their age, can suffer from them. Hence, there is a need of the hour to go for regular heart check-ups and to initiate timely treatment for heart problems.

Myth 2: If you are fit, your heart is SAFE

Fact: So, being physically active is important, but it does not reduce the chances of heart problems. Be attentive to the family history, genetics, and other factors such as high cholesterol or even stress. So, go for cardiac screening on a yearly basis to know the status of your heart health. Discomfort in the arms, jaw, or back and light-headedness can also mean that your heart is in danger.

Myth 3: Heart disease is only seen in men

Fact: Shockingly, heart disease also causes higher morbidity and mortality rates in women. The symptoms seen in women linked to heart disease are dizziness, palpitations, and even giddiness. Hence, women should also focus on their heart health. Stay alert, stay safe!

Your heart health matters. By understanding the facts and making informed choices, it is possible for everyone to protect their heart and overall well-being.

Parkinson's disease is a condition that affects people with Parkinson's ability to move and do things on their own. People with Parkinson's disease will find that it gets worse over time. At first, medicines can help people with Parkinson's disease.

After a while, these medicines might not work as well as they used to for people with Parkinson's disease. Some people with Parkinson's disease might even feel bad because of the medicines they are taking for Parkinson's disease.

That is when doctors might suggest something called Deep Brain Stimulation, or DBS for short, to people with Parkinson's disease. Deep Brain Stimulation is a kind of help for people with Parkinson's disease.

What Is DBS?

DBS is a kind of surgery where doctors put wires into the brain. These wires are connected to a device that is put under the skin in the chest. This device sends messages to the brain to help it work better. The brain can get mixed up. Cause people to shake or move slowly. The messages from the device help fix that.

One of the things about DBS is that it can help people move better when medicines are not working well. People might shake less. Feel less stiff. They might even be able to take medicine, which can be good because it can reduce the side effects.

It is very important to remember that DBS is not a cure for Parkinson's disease. It does not make the disease go away. It can help people do things on their own again. Many people who have DBS say they can eat, walk, and dress themselves better. These are things that can be very hard for people with Parkinson's disease.

DBS Promising For Parkinson's Patients

Doctors have to be very careful about whom they recommend DBS to. It is usually for people who take medicines for Parkinson's disease. The medicines do not always work well. The doctors, surgeons, and therapists all have to work to make sure everything goes well.

Exciting things are happening with DBS. Soon, there might be devices that can adjust on their own to help people more. This means that people with Parkinson's disease might have more hope for feeling better.

DBS is a step forward from just taking medicines. It helps people take control of their bodies again. It helps them feel more independent and dignified. That can make a difference in their daily lives. Parkinson's disease is a hard condition to deal with, but with DBS, people might feel like they can do things again. They might feel like they have their life back. DBS is a promising treatment for people with Parkinson's disease.

Work, school, competition—stress appears to be inevitable these days. Across age groups, many are dealing with it in some form or the other, but unfortunately stress never stops at just headaches or fatigue. It has direct effects on an individual's health through causing disease (such as cardiovascular problems); it also has indirect effects on health by negatively influencing other health behaviors such as physical activity and sleep. It is also vital to note that stress is one of the leading health risks for people in the work environment. Healthcare professionals are advised to consider both major stressors and those that occur regularly. Further discussion about stress reduction strategies is provided.

Dr Anshuman Kaushal, Director of Robotic GI, Minimal Access & Bariatric Surgery at CK Birla Hospital, Gurugram, in an interview with Health and Me, spoke about the long-term effects of chronic stress and why it can be termed a lifestyle disorder.

Mechanisms of Chronic Stress

Exposure to certain stressors activates the HPA axis, and as a result, adrenaline and cortisol are released. While these hormones play a crucial role in survival during emergencies, they can result in serious health problems when continuously present in the body. Some of the most common consequences of stress are low immunity, insulin resistance, or inflammation. It can over time result in hypertension or heart disease.

Lifestyle as the Main Cause

With growing rates of urbanisation, competitive workplaces, financial issues, and the development of technology leading to a permanently accessible Internet, the boundaries between working time and time for rest have been blurred entirely. Moreover, an insufficient amount of sleep, poor sleeping habits, and a sedentary lifestyle cause stress as well. The young generation in India has become victims of stress-related disorders the most.

Identification of the Symptoms

One of the major challenges when identifying chronic stress cases lies in the subtlety of the condition. The list of symptoms includes constant fatigue, irritability, concentration issues, headaches, tight muscles, and insomnia. Other symptoms of the condition include gastrointestinal disorders such as acid reflux, bloating, and loss of appetite that are hardly ever associated with stress.

Long-term effects of stress

Chronic stress may appear harmless, but the truth is quite contrary. When an individual is stressed for too long without controlling it, it may result in anxiety disorders like depression. Physiological side effects of stress are:

1. Poor immunity
2. Inflammation
3. Obesity
4. Diabetes
5. Weakened memory
6. Mood swings

What makes chronic stress a lifestyle disease?

While most lifestyle disorders are caused by environmental factors and behavioural alterations, it can be termed a lifestyle disease. These disorders are progressive and require constant intervention in the form of medication or meditation.

Managing chronic stress

Doctors say that it takes a comprehensive strategy to reduce cortisol levels in the body and uplift mood. For instance, workouts like weight training or yoga are known to increase levels of happy hormones, thereby reducing stress. Breathing exercises and meditation, too, have a positive impact on mental health. Experts recommend combining them with nutrition, proper sleep, and socialising.

Early diagnosis matters

Chronic stress is not just a symptom of modern life but also a key health problem. Recognising it as a health issue and addressing it helps combat the long-term consequences well in time. And with continued changes in lifestyle habits and patterns, a lifestyle disease like chronic stress can also be brought under control for the better.
