New study could help reduce number of sports-related head injuries - and deaths from catastrophic impacts
Head injuries are a common risk in many sports, from cricket, rugby, football and roller derby to name a few.
Some studies suggest up to 40 per cent of athletes will suffer an injury over a year's worth of training and competing.
In sports like cricket the risk can rise to 70 per cent, with just over one in 10 of these injuries to critical areas like the head, neck and face mainly due to a hard ball launched at high speeds from bowler to batsman
The consequences of such injuries can be devastating.
Aussie cricketer Phillip Hughes, 25, was famously killed in 2014 after a devastating head injury delivered by a bouncer bowled by Sean Abbott.
He was later confirmed to have died from a vertebral artery dissection, a tear in one of the arteries in the neck that feeds the brainstem oxygen rich blood. Such an injury carries the risk of causing a stroke.
Now, a team of researchers have come up with a way to assess the best helmet material to reduce serious head injuries.
Scientists from Chongqing Jiaotong University alongside Chongqing No. 7 Middle School, analysed the performance of three different helmet materials.
These were a strong plastic called Acrylonitrile Butadiene Styrene (ABS), fibreglass alloys, and aluminium composites.
Using computer simulations, the team made digital copies of helmets made from each material.
These digital helmets were then put through a variety of computerised impact scenarios based on cricket with the team analysing how well they protected a simulated human head and brain within.
They found that for training and at a recreational level an ABS helmet provided sufficient protection.
However, at an elite level—where balls travel at a faster, and therefore more dangerous, speed—fibreglass or aluminium alloys performed better.
They added while either of these had its advantages, they noted that fibreglass being more brittle than aluminium gave it an advantage as it distributed the stress of an impact across its entire surface, lowering the risk of a traumatic injury.
Author of the study, which was published in the journal AIP Advances, Tao Wang said while the results are interesting they are not universal to every sport which each have their unique stresses.
'Each sport should be checked individually, because loading conditions are different in different sports,' he said.
Government data suggests there are about 6,500 sports related concussion admissions to hospitals in England per year.
The issue of head injuries in sport has come under increasing focus in recent years due to fears that repeated blows could increase the risk of dementia.
A 2023 study commissioned by the Football Association and Professional Footballers' Association, found professional footballers have triple the likelihood of being diagnosed with dementia than the general population.
However, subsequent studies have found this isn't likely to be a risk for amateur players.
In fact, playing sport was found to be protective against dementia most likely due to regularly doing exercise a known factor that protects against the memory robbing disorder.

Can't sleep? The 4 exercises proven to beat insomnia and improve sleep quality revealed
STRUGGLING to sleep? Get your exercise gear on, scientists suggest. They revealed four workouts that could help beat insomnia and improve sleep quality. 2 Yoga, known for its deep stretches and meditative breathing, made the list, as did Tai Chi - a Chinese martial art. But exercise as simple as walking and jogging could also help you snooze better, researchers from Beijing University of Chinese Medicine found. They suggested exercise be used a primary treatment strategy for persistent poor sleep - especially since it's cheap and has minimal side effects. If you regularly have trouble falling asleep, wake up lots during the night or wake up early and can't drift off again, this means you have insomnia. It can last for days, weeks or months - it's deemed 'long-term' if it passes the three month mark, according to the NHS. Long term issues with sleep can up the risk of mental and physical health conditions, including depression, heart problems, obesity and dementia. Cognitive behavioural therapy (CBT) is often suggested as a form of treatment, if making changes to your sleep routine doesn't work. In the UK, GPs now rarely prescribe sleeping pills to treat insomnia, as they can have serious side effects. Instead they will often suggest insomnia sufferers take time to wind down before bed, make sure their bedroom is dark and quiet, and exercise regularly throughout the day. Studies also suggest that exercise can be helpful for insomnia, but current guidelines don't specify which types of exercise might be most beneficial, the Chinese research team said. I spent three days at a sleep retreat - these are the top 7 things I learnt Their research - published in BMJ Evidence Based Medicine - compared 22 different clinical trials on treatment options to ease insomnia. The trials involved 1348 participants and 13 insomnia treatments, seven of which were exercise-based. These were: Yoga Tai Chi Walking or jogging Aerobic plus strength exercise Strength training alone Aerobic exercise combined with therapy Mixed aerobic exercises Participants tried these workouts for four up to 26 weeks at a time. The other insomnia treatments studied included CBT, changes to sleep hygiene, Ayurveda, acupuncture and massage, and lifestyle changes typically recommended for the condition. A number of trials found CBT is "more effective and has a longer-lasting impact on insomnia than medication", researchers said. CBT helped insomnia sufferers increase their total sleep time, improve their sleep efficiency, shorten the amount of time spent awake and helped them fall asleep faster, according to studies they assessed. INSOMNIA means you regularly have problems sleeping. You have insomnia if you regularly: Find it hard to go to sleep Wake up several times during the night Lie awake at night Wake up early and cannot go back to sleep Still feel tired after waking up Find it hard to nap during the day even though you're tired Feel tired and irritable during the day Find it difficult to concentrate during the day because you're tired The most common causes are: Stress, anxiety or depression Noise A room that's too hot or cold Uncomfortable beds Alcohol, caffeine or nicotine Illegal drugs like cocaine or ecstasy Jet lag Shift work Insomnia usually gets better by changing your sleeping habits. Try going to bed and waking up at the same time every day, and relaxing at least one hour before bed, for example, take a bath or read a book. Make sure your bedroom is dark and quiet, exercise regularly during the day, and make sure your mattress, pillow and covers are comfortable. Avoid the following: Do not smoke or drink alcohol, tea or coffee at least six hours before going to bed Do not eat a big meal late at night Do not exercise at least four hours before bed Do not watch television or use devices, like smartphones, right before going to bed, because the blue light makes you more awake Do not nap during the day Do not drive when you feel sleepy Do not sleep in after a bad night's sleep and stick to your regular sleeping hours instead You can buy tablets or liquids (sometimes called sleeping aids) from a pharmacy that may help you sleep better. But if you find nothing is helping your insomnia, see your GP. Source: NHS But some forms of exercise also seemed to be effective, when compared to the usual treatment given to people with insomnia. Yoga could increase total sleep time by nearly two hours and improve sleep efficiency by nearly 15 per cent, researchers found. It may also help people fall asleep half an hour faster and reduce time spent awake during the night by nearly an hour, they added. Tai Chi may also increase total sleep time by more than 50 minutes, reduce time spent awake by over half an hour and shorten the falling asleep process by around 25 minutes, scientists found. In fact, out of all the exercise types, Tai Chi seemed to ease insomnia most effectively for up to two years. Walking or jogging also seemed to reduce insomnia severity. Researchers said there are biological explanations for why exercise can help people sleep better. As yoga focuses on body awareness, attention and controlled breathing, it may alter brain activity, helping ease anxiety and depressive symptoms, which often interfere with a good night's sleep, the study team suggested. As for Tai Chi, its emphasis on breath control and physical relaxation has been shown to decrease activity in the sympathetic nervous system activity, which is responsible for the body's 'fight or flight' response. Its focus on meditative movement and mindfulness may also help dull 'mental chatter', reduce anxiety and reduce inflammation in the body. Walking or jogging may improve sleep by increasing energy expenditure, stopping cortisol production, improving emotional regulation and boosting the sleep hormone melatonin, researchers added. They noted that 15 of clinical trials the included in their analysis had flaws in their design and methods. Some of the participant pools were also small, and there wasn't a standard way of assessing the frequency or intensity of workouts across all of the studies. But they concluded: 'The findings of this study further underscore the therapeutic potential of exercise interventions in the treatment of insomnia, suggesting that their role may extend beyond adjunctive support to serve as viable primary treatment options. 'Although current clinical guidelines make only limited mention of exercise, this study provides relatively comprehensive comparative evidence that may inform the development of more specific and actionable clinical recommendations. 'Given the advantages of exercise modalities such as yoga, Tai Chi, and walking or jogging — including low cost, minimal side effects, and high accessibility — these interventions are well-suited for integration into primary care and community health programmes.' They called for further research what types of exercise may help ease specific insomnia symptoms.

Yoga, tai chi, walking and jogging best ways to tackle insomnia
Yoga, tai chi, jogging and walking could be the best forms of exercise to help tackle the sleep disorder insomnia, a study suggests. These workouts are 'well-suited' to be recommended to patients due to their low cost and minimal side-effects, researchers said. People with insomnia regularly have trouble falling asleep, staying asleep, or wake several times during the night. It can cause people to have difficulty concentrating or to be tired and irritable during the day. To explore the effectiveness of different workouts on sleep quality and insomnia, researchers in China analysed 22 trials. The review included 1,348 patients and 13 different measures to boost sleep, including seven exercises: yoga, tai chi; walking or jogging; aerobic plus strength exercise; strength training alone; aerobic exercise combined with therapy; and mixed aerobic exercises. The study found that yoga, in particular, resulted in an increase in sleep time of almost two hours, and could also cut the amount of time spent awake after falling asleep by nearly an hour. Walking or jogging could reduce insomnia severity, while tai chi could boost sleep quality. According to researchers, yoga's focus on body awareness and controlled breathing could help with symptoms of anxiety and depression to help people get a good night's sleep. Tai chi, an ancient Chinese martial art that involves slow, flowing movements, 'emphasises breath control and physical relaxation', they added, and could boost emotional regulation. Elsewhere, the study suggests walking or jogging could reduce levels of the stress hormone cortisol, while boosting melatonin, the hormone that regulates sleep cycles. Researchers said: 'The findings of this study further underscore the therapeutic potential of exercise interventions in the treatment of insomnia. 'Given the advantages of exercise modalities such as yoga, tai chi, and walking or jogging – including low cost, minimal side effects, and high accessibility – these interventions are well-suited for integration into primary care and community health programmes.' Researchers stressed there were some 'methodological limitations' to some of the trials included in the analysis. However, they said the study, published in BMJ Evidence Based Medicine, 'provides comprehensive comparative evidence supporting the efficacy of exercise interventions in improving sleep outcomes among individuals with insomnia'. They also called for large-scale, high-quality trials to confirm and extend their findings. Other non-exercise-based approaches in the trials included the likes of cognitive behavourial therapy (CBT), acupuncture, massage and lifestyle changes. A number of trials found CBT is 'more effective and has a longer-lasting impact on insomnia than medication', researchers said. However, they highlighted a number of 'barriers' to CBT, including a lack of trained professionals.

New health study reveals the exercises that can help insomnia
Yoga, tai chi, jogging, and even a simple walk could be the most effective forms of exercise to combat the sleep disorder, insomnia, a new study suggests. Researchers advocate for these activities, noting their suitability for patient recommendation due to their low cost and minimal side-effects. Insomnia, characterised by persistent difficulty falling or staying asleep, or frequent nocturnal awakenings, can significantly impair daily life, leading to issues with concentration, fatigue, and irritability. To ascertain the efficacy of various physical activities on sleep quality and insomnia, researchers in China conducted a comprehensive analysis of 22 trials. The review encompassed 1,348 patients and evaluated 13 distinct measures aimed at improving sleep, including seven specific exercise regimens: yoga, tai chi, walking or jogging, combined aerobic and strength exercise, strength training alone, aerobic exercise paired with therapy, and mixed aerobic exercises. The study found that yoga, in particular, resulted in an increase in sleep time of almost two hours, and could also cut the amount of time spent awake after falling asleep by nearly an hour. Walking or jogging could reduce insomnia severity, while tai chi could boost sleep quality.
