Mold is a type of fungus that has been found on the surface of the earth for millions of years. They can get inside your home through open doors, windows, and air conditioning systems. Inhaling mold spores or coming into contact with mold can have severe adverse effects on your health. Beyond physical symptoms like headache and allergic symptoms, it can have a significant impact on the brain and nervous system. Symptoms may vary, from mild headaches to more severe issues like memory loss or difficulty walking. While it can affect anybody, certain groups like children, the elderly, pregnant women, and those with weakened immune systems are particularly vulnerable to these effects.

How can mold impact your neurological health?

Mold, such as Cladophialophora bantiana, can cause infections in the brain and spinal cord, leading to serious conditions like central nervous system (CNS) infections. While such infections are rare, they can be life-threatening.

Mycotoxins are toxic chemicals produced by certain mold types. These toxins can be released into the air when mold grows indoors, and breathing them in can have direct harmful effects on brain function. Studies indicate that mycotoxins may interfere with the nervous system’s communication pathways, leading to cognitive issues such as memory problems and mood swings.

In fact, long exposure to mold can lead to a variety of neurological symptoms, which can differ depending on an individual’s health and the severity of the mold exposure. Some of them are:

Headaches are one of the most frequent symptoms of mold exposure. While most of the time, these headaches are described as dull, constant, or pressure-like, they can sometimes mimic migraines, accompanied by nausea or sensitivity to light and sound.

Exposure to molds can also trigger seizures. Mold produces toxic substances like mycotoxins that may disrupt the brain’s electrical activity, leading to seizure episodes.

Mold exposure can cause brain fog, which results in concentration, memory, and mental clarity. Studies suggest that mycotoxins can disrupt normal brain function, making it challenging to process information and think clearly.

Exposure to this fungus can also lead to emotional problems. People with this kind of exposure have complained of anxiety, depression, irritability, and sudden mood swings. This could be due to mold toxins interfering with brain chemicals responsible for regulating emotions.

Mold exposure may trigger inflammation, leading to muscle and joint pain. In case of prolonged exposure, it could lead to the development or worsening of fibromyalgia or complex regional pain syndrome (CRPS).

In some cases, mold exposure may lead to tremors, difficulty walking, or problems with muscle coordination. These issues may be linked to mycotoxins affecting the brain or nervous system.

Mold exposure can impact the brain areas responsible for movement and balance, making it harder to stand, walk, or perform fine motor tasks. Individuals may feel unsteady or experience difficulty using devices like phones or computers.

Delirium is a condition wherein a person experiences confusion or disorientation. An abnormal immune response to mold could contribute to this condition. Delirium can make it difficult for individuals to think clearly or understand their surroundings.

A senior British cardiologist has shared a clear two-word tip that he says can make a real difference to your blood pressure. Dr Amir Khan recently explained this advice while outlining five simple habits that can naturally bring hypertension under control, particularly during the winter months when heart risks tend to rise.

India continues to struggle with a heavy hypertension burden. Roughly one in three adults is estimated to have high blood pressure, yet many remain unaware of their condition, and even fewer manage it well. Doctors often warn that this lack of awareness, combined with poor control and gaps in long-term care, leads to serious complications such as heart attacks, strokes, and kidney disease. Since hypertension usually comes without symptoms, it has long been known as a silent killer.

Dr Khan highlights that a few lifestyle tweaks can go a long way, and his biggest message is built around a simple two-word mantra: “get moving”. He explained on Instagram that regular physical activity keeps blood vessels flexible and supports healthy blood flow. His advice is to pick any form of movement you genuinely enjoy and make it part of your routine.

How movement actually helps

Exercise reduces blood pressure by strengthening the heart, improving circulation, and reducing the strain on arteries. A stronger heart pumps blood more efficiently, which lowers the force exerted on blood vessel walls. Physical activity also opens up small blood vessels, helps manage weight, and reduces inflammation and stress hormones. All of these support healthier vascular function and better overall pressure control.

Doctors recommend a mix of aerobic activity, such as brisk walking, swimming, or cycling, along with strength training to support long-term heart and metabolic health.

Other helpful changes, according to Dr Khan

While movement is his main message, Dr Khan also lists four additional habits that support healthier blood pressure levels.

Reduce salt intake

He explains that those with high blood pressure need to be especially mindful of hidden salt. Adults should ideally stay around six grams a day, which is about a teaspoon. Much of this is already present in packaged or restaurant foods. Using herbs, spices, and fresh ingredients can help bring the total down.

Add more potassium-rich foods

Dr Khan encourages increasing potassium intake because it helps the kidneys flush out excess sodium. Foods rich in potassium include bananas, tomatoes, spinach, carrots, and kiwi. Adding these regularly can make a noticeable difference.

Avoid smoking and alcohol

He stresses that avoiding cigarettes and limiting alcohol is key for heart health. Smoking damages blood vessels and raises blood pressure, while alcohol can worsen both pressure and weight control.

Maintain a healthy weight

Keeping weight in a healthy range reduces strain on the heart and helps blood vessels function more efficiently. It also improves circulation and reduces the substances that cause vessels to tighten.

Dr Khan’s message is simple. Small and consistent lifestyle choices can noticeably lower blood pressure, and starting early makes a significant difference.

A new study in the European Heart Journal has shed light on a worrying trend. People living with Type 1 and Type 2 diabetes face a much higher risk of sudden cardiac death, and this risk contributes to a significant loss of life expectancy. The findings also suggest that the true burden of sudden cardiac death in the diabetes population has been underestimated until now.

A Higher and Earlier Risk Than the General Population

Sudden cardiac death refers to an unexpected loss of heart function, often triggered by a sudden electrical disturbance in the heart. While many people assume this happens mainly to those with known heart problems, earlier research has shown that a large number of cases occur in individuals without diagnosed cardiac disease. This means vulnerable groups like people with diabetes may slip through the cracks of current prevention strategies.

People with diabetes already face a shorter lifespan compared to the general population. On average, a 30-year-old with Type 1 diabetes loses about 14.2 years of life, while someone with Type 2 diabetes loses around 7.9 years. A major share of this reduction is linked to cardiovascular disease, and the latest study estimates that sudden cardiac death alone accounts for 3.4 years lost in Type 1 diabetes and 2.7 years in Type 2 diabetes.

What the Danish Study Revealed

To better understand the scale of the problem, researchers examined a nationwide cohort that included every person living in Denmark throughout 2010. For those who died during that year, detailed information was collected from medical records, autopsy findings when available, and death certificates. Two physicians independently reviewed every potential sudden death to ensure accuracy.

The dataset included more than 5.5 million people. During the year, 54,028 deaths occurred, and more than 14 percent were sudden deaths. People with diabetes made up a significant portion of these cases. There were 25,020 individuals with Type 1 diabetes and 172,669 with Type 2 diabetes, with 97 and 1,149 sudden cardiac deaths recorded in each group.

People with diabetes who experienced sudden cardiac death tended to be younger and more often male compared with people without diabetes. They also carried a heavier burden of other medical conditions, including ischemic heart disease, heart failure, arrhythmias, kidney disease, and even mental health issues. A notable proportion of these patients had also been hospitalized for diabetes-related complications such as hypoglycemia, which researchers believe could play a role in triggering sudden cardiac events.

Numbers That Highlight the Gap

The incidence of sudden cardiac death in the general population was 105 per 100,000 person years. In contrast, it climbed to 394 for people with Type 1 diabetes and 681 for those with Type 2 diabetes. The relative risk was especially striking among younger adults. For example, people between 30 and 40 with Type 1 diabetes had more than twenty times the risk compared to those without diabetes.

A Clear Need for Better Prevention

The research team used multiple statistical models to adjust for factors like age and existing disease, and diabetes consistently emerged as an independent risk factor. The findings confirm that sudden cardiac death is responsible for a meaningful portion of life years lost in people with diabetes. They also point to a need for better screening, earlier management of cardiovascular risks, and more focused research into why this group is so vulnerable.

Long winters are here, and Nordic countries are the most familiar with it. The winters there are long as dark. With little to no daylight and coldest temperature, people in the northern Europe and above the Arctic Circle have now learned to cope mentally and physically with the long winter blues. It begins as early as October and lasts till April for some.

The winter solstice on December 21 signals the shortest day and longest night of the year in the Northern Hemisphere. Even though daylight gradually begins to return after that, winter’s darkness continues to linger. Experts in Norway, Sweden and Finland say this is exactly the time when people need to be intentional about protecting their mood and energy. Here is how they suggest staying balanced, both physically and mentally, during the darkest months.

Keep Your Sleep and Social Rhythms Steady

Dr Timo Partonen, a research professor at the Finnish Institute for Health and Welfare, says that long, dark winters can disrupt the circadian rhythm. With limited daylight, the body struggles to reset its internal clock, which leads to restless nights and sluggish mornings. People may sleep more during winter but still wake up tired.

Partonen recommends using a dawn simulator, often called a sunrise alarm clock, which gradually brightens the bedroom and helps the brain ease into waking up. He also notes that people tend to withdraw socially during the winter and may become more irritable. Staying connected to friends and maintaining relationships can soften the impact of the winter blues. Pairing social time with exercise, such as going for a walk or a workout together, can also help maintain energy and mood.

Winter cravings for carbohydrates are common, especially in the evenings. These cravings can lead to weight gain of two to five kilograms a year, Partonen says, so regular activity becomes even more important.

Why Light Therapy Matters

Seasonal depression affects millions worldwide. Many people experience symptoms in the fall and winter that ease once spring arrives. Researchers have discovered that certain cells in the eye respond to blue wavelengths of light, triggering alertness and affecting mood. Sunlight is naturally rich in blue light, so shorter winter days can have a significant impact.

A University of Pittsburgh study found that people with seasonal depression were less sensitive to blue light during winter. This suggests a link between light exposure and mood. For severe symptoms, clinical care and antidepressants may be necessary, but Swedish pharmacology professor Christian Benedict says that light therapy is helpful for both diagnosed seasonal depression and mild winter blues.

Morning sessions with a light therapy box that emits around 10,000 lux can help reset the circadian rhythm and boost serotonin. Devices can range from seventy to four hundred dollars, and insurance may help cover costs for people diagnosed with seasonal affective disorder. Experts advise using a sunrise simulator along with a light therapy lamp before noon.

Embracing Winter as a Mindset

Ida Solhaug, a psychology professor at the University of Tromsø, says that mindset plays a huge role in handling the long winter. Instead of dreading the season, she encourages embracing it. This positive, practical approach is deeply rooted in Nordic culture.

She recommends enjoying indoor coziness with blankets and warm drinks, but also getting outside regularly. Even on cloudy days, a short walk can lift energy levels. Traditional winter activities like a Swedish fika outdoors, or even a cold plunge, can help people feel refreshed. Solhaug swims in the icy waters near Tromsø once a week and says it gives her a renewed sense of vitality.

Nordic culture also emphasizes dressing well for the weather. As locals often say, there is no bad weather, only bad clothing.

Finland’s President Alexander Stubb also shared his own winter survival advice: take an ice bath, follow it with a sauna, then repeat the cycle before heading out into the day.

If winter feels heavy, the experts’ message is clear. Look for light wherever you can find it, take care of your body clock and stay connected. Even in the darkest months, small daily habits can bring warmth and balance.
