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.

The NHS has released a warning for people who take levothyroxine to manage thyroid conditions. With an estimated 33 million prescriptions issued every year across the UK, levothyroxine is among the most frequently prescribed medicines provided by the NHS.
Levothyroxine is mainly used to treat an underactive thyroid, a condition medically known as hypothyroidism. Depending on a patient’s needs and a GP’s assessment, the medicine is usually prescribed either as a tablet or as a liquid taken by mouth.
The NHS website explains that while most adults and children can safely take levothyroxine, there are specific situations where it may not be recommended. These restrictions are based on a person’s medical history and current health conditions.
According to NHS guidance, levothyroxine may not be suitable if any of the following apply:
Levothyroxine can cause a range of side effects, some of which may require urgent medical attention. Common side effects associated with the medication include:
The NHS notes that this is not a complete list, and other side effects may occur. Patients are advised to read the information leaflet included with their medication for full details.
Although these side effects can be unpleasant, they are usually mild and do not typically require a hospital visit. If symptoms persist or become troublesome, the NHS recommends speaking to a doctor or pharmacist for advice.
However, certain symptoms should not be ignored. If you notice a fast or irregular heartbeat while taking levothyroxine, you should contact a doctor or call NHS 111 as soon as possible.
More serious symptoms require immediate action. Anyone experiencing chest pain while on levothyroxine is advised to call 999 without delay, as this could signal a medical emergency.
Disclaimer: This article is for general information only and is not a substitute for medical advice. Levothyroxine should be taken only as prescribed by a qualified healthcare professional. Do not start, stop, or change your medication without consulting your doctor. If you experience severe symptoms or a medical emergency, seek immediate medical attention or call emergency services.

Delhi, on Wednesday morning, woke up to 'very poor' air. The visibility was low and, in fact, the India Meteorological Department (IMD) issued an orange alert for dense fog between 8.30am and 10am. Visibility remained low, and as per the 24-hour average Air Quality Index, Delhi stood at 384, as confirmed by the data from the Central Pollution Control Board (CPCB). In certain areas, including Anand Vihar, AQI remained under 'severe' level, at 452.
This has resulted in cancellation of t least 148 flights and over 150 flights were delayed at the Delhi airport.
However, there may be a silver lining, in an interview with TOI, Tarun Kumar Pithode, who took charge as the new full-time member secretary of the Commission for Air Quality Management (CAQM) said that Delhi can expect "more blue-sky days over next 3-4 years".
Delhi’s fight against air pollution is set to intensify over the next few years, with the CAQM outlining a multi-pronged plan aimed at delivering “more blue-sky days” for the capital. Rather than relying on emergency measures alone, the strategy focuses on long-term, structural fixes across transport, industry, energy and regional coordination.
One of CAQM’s core priorities is reducing pollution from vehicles, which remain a major contributor to Delhi’s poor air quality. The plan pushes for faster adoption of electric vehicles, tighter checks on polluting commercial vehicles, and a stronger public transport network. Scrapping old, high-emission vehicles and discouraging diesel use through stricter enforcement are seen as key steps to curb everyday emissions, not just during winter spikes.
Industrial pollution is another major target. CAQM has stressed a shift away from coal and other dirty fuels toward cleaner energy sources. Industries operating in and around Delhi are being pushed to adopt cleaner fuels such as natural gas, along with better emission-control technologies. Power plants in the region are also under scrutiny, with stricter norms to ensure they do not become pollution hotspots during peak winter months.
Construction dust and road dust significantly worsen Delhi’s air quality, especially during dry months. CAQM’s plan includes stricter enforcement of dust-control norms at construction sites, better mechanised road sweeping, and regular water sprinkling on major roads. Authorities are also being asked to improve urban planning to reduce exposed soil and unpaved areas that contribute to dust pollution.
A major part of Delhi’s pollution problem comes from outside the city, particularly crop residue burning in neighboring states. CAQM has emphasized regional coordination, working with states like Punjab, Haryana and Uttar Pradesh to reduce stubble burning. This includes promoting alternative methods for crop residue management, providing financial incentives, and ensuring accountability when violations occur.
Unlike earlier approaches that focused largely on winter emergencies, CAQM’s plan relies on year-round monitoring and data-driven action. Expanded air-quality monitoring, better forecasting, and early interventions are expected to prevent pollution levels from spiralling out of control. The aim is to move from reactive crisis management to consistent prevention.
CAQM officials acknowledge that Delhi’s pollution problem will not disappear overnight. However, with coordinated action across sectors and states, they believe the capital can see steady improvement over the next three to four years. The promise of more blue-sky days hinges not just on policy, but on strict enforcement and sustained public cooperation.

"There is a big mistake you are making when you fly and no one talks about how to prevent it," writes Dr Rema Malik, a board-certified vascular surgeon, based in Houston, Texas. On her Instagram post she talks about how our body deals with much of a serious challenge once we enter the plane and the cabin doors shut. She points out that while most of us are busy settling into our seats, our veins enter a risky environment that could raise the chance of developing a blood clot. These risks include deep vein thrombosis or DVT. She points out that this risk is not just limited to older adults, but to people with known health issues too.
Dr. Malik explains that air travel creates what she calls a “three-hit combo” that puts your circulation under stress.
First is prolonged sitting. When you stay seated for hours, your calf muscles, often called your second heart, stop doing their job. These muscles help push blood back up toward the heart. Without movement, blood begins to pool in the legs instead of flowing upward.
Second comes dehydration. Cabin air is extremely dry, far drier than most natural environments. This causes your body to lose moisture faster than you realize. As dehydration sets in, your blood becomes thicker and more sluggish, which makes clot formation easier.
The third factor is cabin pressure. Lower pressure at cruising altitude causes veins to dilate or expand. This stretching weakens the tiny valves inside your veins that normally prevent blood from flowing backward. Gravity then does the rest, encouraging blood to settle in the lower limbs.
This combination is not about discomfort. It is about safety.

There is a common belief that blood clots only affect the elderly or people with chronic illnesses. Dr. Malik strongly disagrees. Whether you are 25 or 65, long flights place similar stress on your circulation. Sitting still, dehydration, and pressure changes affect everyone, regardless of how fit or young they feel.
That is why she recommends preparing your body for travel just as seriously as you prepare your suitcase.
Compression socks are not just for people with medical conditions. Dr. Malik calls them non-negotiable for air travel. A compression level of 15 to 20 mmHg helps mechanically push blood upward, prevents swelling, and supports healthy circulation.
The key is timing. Put them on before you leave home, not after you board the plane, so your veins are supported from the very start.
Her rule is simple. Drink eight ounces of water for every hour you are in the air. This helps keep your blood from becoming too thick.
Coffee, alcohol, and wine do not count. In fact, they make dehydration worse. If you are serious about flying safely, water needs to be your main beverage.
Every 30 minutes, Dr. Malik recommends doing 30 ankle pumps. Lift your toes up and down as if you are pressing a gas pedal. This simple movement activates your calf muscles and helps clear stagnant blood from your legs, even if you cannot get up and walk.
