Yoga is frequently studied for its potential to relieve chronic low back pain, a condition that in 2020 affected 619 million people globally. Moreover, severe back pain can trigger conditions like arthritis, herniated discs, spinal stenosis, and infections. However, an Italian research team specializing in rehabilitative medicine has made an interesting discovery on yoga's positive impact on lower back pain.

What Was The Research About?

Yoga Showed Reduction In Pain

Yoga poses included in the study, such as Downward-Facing Dog, Pigeon Pose, Child’s Pose, and Cobra Pose, were held for five breaths each. Dr. Alessandro de Sire, one of the study authors, highlighted that these poses can relax muscles and improve mobility. Jivana Heyman, a yoga therapist, added that hip flexion poses help increase the range of motion without overly engaging the lower back.

This study adds to growing evidence supporting yoga as a viable treatment for low back pain. For those interested in starting yoga, experts recommend seeking classes like "Gentle Yoga" or "Accessible Yoga," where instructors can adapt poses to individual needs.

While more research is needed, this study highlights yoga as a valuable addition to managing low back pain, combining physical relief with stress reduction and nervous system regulation.

Yoga Is The Oldest Form Of Exercise

Yoga is the oldest form of exercise and traces its roots back to ancient India. The word "yoga" comes from the Sanskrit word "yuj," which means "to yoke" or "to bind." Interestingly, yoga incorporates physical postures (asanas), breathing techniques (pranayama), and meditation together. While spirituality lists various benefits of yoga, scientific research into it is still at a preliminary stage. However, numerous studies have indicated that it has a significant positive impact on a person's physical and mental health.

Yoga offers diverse benefits, enhancing physical, mental, and emotional well-being. It improves flexibility and joint health, particularly in older adults, while strength-building styles target both upper and lower limbs. Yoga reduces stress through physical practice, meditation, and breathwork, and research supports its effectiveness in alleviating symptoms of depression and anxiety. Practices like Yoga Nidra are particularly beneficial for anxiety relief.

For individuals with chronic pain, yoga improves quality of life and promotes long-term health benefits. Pranayama (yogic breathing) enhances cardiovascular function and strengthens the immune system by reducing inflammation. Yoga supports better sleep, fosters positive body image, and boosts self-esteem, especially in adolescents and young adults. Regular practice improves brain function, posture, and body awareness, counteracting the effects of poor posture and burnout. By promoting mental calm and resilience, yoga provides a holistic approach to maintaining health and well-being.

Winter brings a significant rise in respiratory problems, particularly among people living with asthma. Increased air pollution, falling temperatures and exposure to dust and other airborne irritants can trigger inflammation in the airways, leading to symptoms such as coughing, wheezing, chest tightness and breathlessness.

While these factors can make asthma more difficult to manage, many patients also make treatment-related mistakes that can worsen their symptoms and increase the risk of an asthma attack.

One of the most common mistakes is discontinuing inhalers when symptoms improve. Asthma is a chronic inflammatory condition, and the absence of symptoms does not necessarily mean that the underlying inflammation has resolved. Controller inhalers, particularly those containing inhaled corticosteroids, help reduce airway inflammation and prevent flare-ups.

Stopping these medications without medical advice can leave patients vulnerable to sudden exacerbations, especially during periods of high pollution.

Another concern is the excessive reliance on rescue inhalers. These inhalers provide quick relief by relaxing the muscles around the airways, but they do not necessarily address the underlying inflammation. Frequent use may indicate that asthma is not adequately controlled and that the patient's treatment plan needs to be reviewed by a doctor. Patients should not increase their medication dosage or frequency without appropriate medical guidance.

Incorrect inhaler technique is another frequently overlooked problem. Patients may use their inhalers too quickly, fail to coordinate inhalation with medication release or neglect to hold their breath briefly after inhaling. These mistakes can prevent the medicine from reaching the lungs effectively. Regularly reviewing inhaler technique with a healthcare professional and using a spacer, where recommended, can significantly improve drug delivery.

Many patients also underestimate the importance of continuing their prescribed treatment during symptom-free periods. Some turn to steam inhalation, home remedies or over-the-counter cough medications instead of following their asthma management plan. Although certain supportive measures may provide comfort, they cannot replace prescribed asthma medication. Hot steam can also cause burns and should not be used as a treatment for asthma.

During winter, patients should monitor local air quality, reduce prolonged outdoor exposure when pollution levels are high, avoid tobacco smoke and other respiratory irritants, and keep their prescribed medication accessible. Wearing a well-fitting mask outdoors may help reduce exposure to particulate pollution, although it does not eliminate the risk.

Most importantly, people with asthma should have an individualised asthma action plan and attend regular follow-ups. Worsening breathlessness, difficulty speaking in full sentences or symptoms that do not respond to the prescribed reliever require urgent medical attention. With correct inhaler use, consistent treatment and timely medical review, most patients can manage their asthma more effectively even during highly polluted winter months.

Changes in stride like a slower walking pace, fewer steps or a change in the way your arms move may be considered as signs of ageing. However, an emerging study suggests that minor differences in walking patterns could be subtle, early indicators of Parkinson’s disease. According to the study, these signs can can emerge years before Parkinson's diagnosis.

Published in the Journal of Neural Transmission, the study analysed movement data from more than 73,000 participants in the UK Biobank. Researchers found that certain changes in walking behaviour could indicate a future Parkinson’s diagnosis, surfacing up to 6.8 years beforehand.

The findings indicate that Parkinson’s disease may begin developing long before its more familiar symptoms like tremors and stiffness, become noticeable.

Findings From The Study

Researchers examined data from 73,413 people who wore wearables that track movement for seven days. Their health records were then followed for up to 10 years. Of the participants without Parkinson’s at the time of the movement assessment, 314 were diagnosed with the disease during follow-up.

Using a digital analysis tool called Watch Walk, researchers examined 17 characteristics related to gait. They identified five walking characteristics that were consistently linked with a subsequent Parkinson’s diagnosis:

• Fewer steps each day: Participants who later developed Parkinson’s recorded lower daily step counts than those who did not.
• Slower walking speed: People who were diagnosed later tended to walk more slowly, including at their maximum walking speed.
• Shorter walking periods: They also spent a lesser amount of their time walking in longer, continuous stretches.
• Changes in step regularity: Their steps showed less consistent rhythm, indicating alterations in the regularity of their walking pattern.
• Reduced natural arm swing: They spent more time walking with their arms in a static position instead of swinging naturally.

Parkinson’s disease is a progressive neurological disorder that affects movement. It occurs due to the loss of nerve cells that produce dopamine in a brain region called the substantia nigra. Dopamine helps regulate movement, coordination and other functions.

As dopamine levels decline, the brain's ability to coordinate movement is affected. This can lead to bradykinesia, or slowness of movement, rigidity of muscle, tremors and balance issues.

These changes can also affect gait. A person may take smaller steps, walk more slowly, experience difficulty moving or reduced swinging arms.

The study's findings suggest that some of these motor changes may be detectable in everyday movement well before the condition is formally diagnosed.

Changes in walking speed, balance, step length or arm movement can occur for several reasons, including ageing, joint problems, injuries, medication effects and other neurological conditions.

Parkinson’s disease is, however, diagnosed through a clinical assessment, which considers a person's symptoms, medical history and neurological examination. Other symptoms that may warrant medical evaluation include:

• A tremor especially when the affected hand or limb is at rest.
• Slowness in everyday movements like dressing or getting up from a chair.
• Muscle stiffness or rigidity.
• Problems with balance.
• Smaller handwriting or changes in speech volume.

Early Detection Of Parkinson’s Disease

Although there is currently no established treatment that stops or reverses the underlying progression of Parkinson’s disease, an earlier diagnosis can help people manage symptoms, access rehabilitation and support sooner.

Exercise, physiotherapy and medical care can help maintain mobility, balance and quality of life. Early assessment can also help doctors distinguish Parkinson’s from other conditions that may cause similar movement difficulties.

After the social media trend of ‘ferritin face’ had everyone scrutinising their face for pale skin, dark circles and sluggish features due to low iron levels, attention is now shifting to hair. Described as ‘ferritin hair’, social media users have been attributing symptoms like unusual hair shedding, thinning and brittle strands to the body’s low iron stores.

The trend is not just a fluke. There is a medical basis for recognising iron deficiency in people facing hair loss. However, ‘ferritin hair’ is not a formal medical diagnosis. Hair loss can be due to several reasons, including hormonal changes, stress, thyroid disorders, nutritional deficiencies and genetic hair-loss conditions.

So is there a connection between ferritin and hair health and which signs should prompt someone to seek medical advice?

Ferritin is a protein that stores iron in the body and releases it when needed. A blood ferritin test helps assess the body's iron reserves. Iron is essential for several functions, including the production of haemoglobin, which carries oxygen in the blood.

When iron stores are exhausted, the body prioritises essential functions over those that are not absolutely necessary for survival. Hair growth may be affected in some people, contributing to increased shedding.

A 2023 clinical review published in Cutis noted that measuring serum ferritin can be useful while evaluating people with diffuse hair loss, especially to identify underlying iron deficiency.

A 2026 study published in Cureus reported that low serum ferritin and telogen effluvium in women may be connected.

A separate systematic review published in 2026 also found lower ferritin levels among people with telogen effluvium.

The European Food Safety Authority has also observed a cause-and-effect relationship between iron intake and the maintenance of normal hair growth.

Possible Signs Of 'Ferritin Hair'

Hair shedding: One possible sign is diffuse hair shedding, in which more hair than usual falls from across the scalp rather than from one specific area. This can occur due to a condition called telogen effluvium, in which more hair follicles than usual enter the resting phase of the hair-growth cycle.

Hair thinning: Constant shedding can make the hair appear less dense over time. Some people may notice a wider-looking parting or thinner volume.

Dry or brittle hair: Iron deficiency may cause dry, brittle hair. However, hair texture can also be affected by heat styling, chemical treatments and other nutritional factors.

Other symptoms: Hair shedding may occur with other signs of iron deficiency like fatigue, weakness, poor concentration, breathlessness, palpitations or pale skin.

Causes Of Iron Deficiency Or Low Ferritin Levels

Iron deficiency can develop when the body loses more iron than it absorbs and does not receive enough through diet. Heavy menstrual bleeding and pregnancy are common reasons for iron deficiency. Other possible causes include:

• Inadequate dietary iron: People who do not consume enough iron-rich foods are at risk if their diets are restrictive.
• Poor absorption: Conditions such as coeliac disease can interfere with the absorption of iron.
• Blood loss: Gastrointestinal conditions like gastritis and intestinal polyps can sometimes lead to iron loss.
• Increased requirements: Pregnancy can demand increased iron needs.
