The world that we live in is filled with sounds, some are comforting and some could be jarring too. But what if the constant noise surrounding us is doing us more harm than we realize? There has been immense research that shows that noise is not just a nuisance, but a silent killer and affects our health in ways we do not even know. There are associations of sound causing heart attacks, type 2 diabetes, and dementia.
Noise is seen as an annoyance, but it effects can go beyond what we imagine. When we hear a sound, it travels through the ear to the brain. This is where it gets processed by the amygdala. It is a region that is responsible for emotional responses. This also triggers a stress response- our heart rate increases, our blood pressure rises, and stress hormones like cortisol flood our system.
This response is also designed to help us react to immediate threats. Especially, if we hear the sound of a predator approaching. However, when we are exposed to constant noise, this response is triggered repeatedly and could compel us to live in a long-term anxious state.
Many studies including Harvard Health and theAmerican College of Cardiology have found associations of noise with health problems including putting a person at a higher risk of cardiovascular diseases such as heart strokes, attacks, and high blood pressure. The constant activation of the stress response can take a toll on the body, increasing inflammation and making it harder for the heart and circulatory system to function properly. Over time, this can lead to serious health conditions like heart disease and diabetes.
Even more troubling, research suggests that noise pollution may contribute to mental health issues. Studies have found a strong connection between exposure to noise and disturbed sleep, which in turn can cause anxiety, depression, and cognitive decline. The World Health Organization estimates that noise contributes to around 12,000 premature deaths annually across Europe alone. This invisible threat, however, is often overlooked because the effects are gradual and cumulative.
One of the most insidious aspects of noise pollution is its impact on sleep. Even when we are asleep, our bodies are not fully immune to the effects of sound. Our ears never fully “turn off,” meaning that even faint noises can disrupt our sleep cycle. Research has shown that people who live in noisy environments—whether near busy roads, airports, or urban centers—often experience fragmented sleep, leading to fatigue and a weakened immune system. Over time, this chronic lack of restful sleep can lead to significant health problems, including an increased risk of developing cognitive disorders such as dementia.
As cities continue to grow, noise pollution is becoming more widespread. Traffic noise, in particular, is one of the most common and harmful sources. The rise of urbanization means more cars, buses, and trains, all of which contribute to an ever-increasing din. This urban soundscape is often relentless, with little respite for those living within it. In densely populated cities, people are exposed to high decibel levels, which can exceed safe thresholds for heart health. In many cases, the sheer volume of sound is not just unpleasant; it’s dangerous.
The solution is not as simple as reducing noise in our immediate surroundings, though efforts to reduce traffic noise and limit industrial sounds are essential. Some cities have taken steps to create quieter spaces by converting busy roads into pedestrian zones or installing noise barriers. These measures have shown to have a positive impact on public health, with research suggesting that even small reductions in noise can prevent premature deaths and improve overall well-being.

A particular type of cough could offer an important clue about whether you have Covid or flu this winter. The NHS has outlined how the two illnesses can be told apart.
As winter arrives, a noticeable increase in seasonal illnesses is expected. Conditions such as the common cold, respiratory syncytial virus (RSV), COVID-19, and influenza tend to spread more easily during colder months. This happens because viruses thrive in lower temperatures and people spend longer periods indoors, often in close proximity to others.
Distinguishing between these infections is not always easy, as many symptoms overlap. According to guidance published by the NHS, the following symptoms are commonly seen in both Covid and flu:
Flu and Covid are among the illnesses that become more common during the winter months. If you have influenza, the NHS explains that the cough is usually dry and may develop suddenly, often alongside other symptoms that appear quickly.
In contrast, Covid may cause what the NHS describes as a “new, continuous cough.” This refers to coughing frequently for more than an hour, or experiencing three or more coughing episodes within a 24-hour period.
This distinction is supported by Dr Rupa Parmar, a GP and medical director at Midland Health. In previous comments, she noted that coughs linked to colds are generally mild, while flu tends to cause a dry cough.
“With Covid, the cough is often dry and persistent,” she explained. “Many people cough continuously for long periods or have repeated coughing fits throughout the day.”
The type of cough is not the only sign that may help identify which illness you have. A reduced or altered sense of smell or taste is commonly reported in people with Covid and is much less frequent in flu cases.
Breathlessness is another symptom recognised by the NHS as being associated with Covid. While flu can sometimes lead to breathing difficulties, this usually occurs only if the illness becomes severe.
What to do if you have symptoms:
For both Covid and flu, the NHS advises staying at home and limiting contact with others if you or your child have symptoms and either:
When to seek urgent medical advice:
The NHS recommends contacting your GP or NHS 111 urgently if:
Every new year brings familiar promises. Eat better. Move more. Quit smoking. Stress less. According to Harvard Health Publishing, the reason these resolutions often fade is not a lack of intent, but the absence of habits that can hold steady once everyday life takes over.
If 2026 is the year you want real, lasting change, the focus needs to shift from short bursts of motivation to health habits that are realistic, repeatable, and kind to your body.
Drawing from insights shared by Harvard Health Publishing, here are seven ways to make health goals finally stick.
Harvard Health Publishing notes that goals tied to emotion tend to last longer. Instead of vague aims like “get fit,” think about what truly matters to you. It could be completing a long walk without exhaustion, lowering your blood pressure, or feeling comfortable in your body again. When a goal feels personal, it becomes easier to stay committed.
Big health goals can feel overwhelming. That is why Harvard Health Publishing recommends breaking them into steps that feel almost too easy. A short walk, a few stretches, or one nutritious meal can build confidence. Small actions done consistently often matter more than dramatic efforts done occasionally.
According to Harvard Health Publishing, many unhealthy behaviours offer immediate comfort. Overeating, smoking, or skipping exercise often meet emotional needs like relaxation or relief from stress. Instead of ignoring this, acknowledge it. Find healthier ways to take breaks, unwind, or reward yourself so you are not fighting against your own needs.
Harvard Health Publishing highlights the role of accountability in sustaining behaviour change. Sharing your goal with a partner, friend, doctor, or even a small online group can make a difference. When others know what you are working toward, you are more likely to stay consistent, especially on difficult days.
Health improvements happen gradually. Harvard Health Publishing encourages celebrating effort along the way. Acknowledge days when you move your body, eat mindfully, or manage stress better. These small rewards reinforce the habit and prevent burnout caused by waiting only for visible results.
Missing workouts or slipping into old habits does not mean failure. Harvard Health Publishing advises viewing setbacks as useful feedback. If a plan feels too demanding, scale it back. If time is an issue, break exercise into shorter sessions. Adjusting your approach makes long-term success more likely.
Perfection is not required for better health. As Harvard Health Publishing reminds us, even small amounts of physical activity or healthier choices benefit the body. Ten minutes of movement is still movement. One balanced meal still nourishes you. Gratitude for effort keeps motivation steady and realistic.

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.
