Red lights can prevent visibility from getting worse


One study found that shining red light into a person’s eyes could slow the progression of nearsightedness.

The researchers found that just spending six minutes a day looking at a special red light-emitting binocular-like device slowed the progression of nearsightedness, or nearsightedness, by nearly 70 percent. .

Myopia affects around 40% of the UK population – up from 27% in the 1970s.

It occurs when the eyeball grows too long – more like a rugby ball than a soccer ball – which changes the way light hits the retina, the light-sensitive cells at the back of the eye. visual images to the brain.

An elongated eyeball causes light to focus in front of the retina and as a result near objects appear clear but distant objects appear blurry.

Studies show that cases of myopia may be on the rise as people spend less time outside.

Bright, natural light triggers the release of the chemical messenger dopamine from the retina. It is thought that dopamine controls the correct development of the eyes and low levels may be involved in the development of myopia. Research groups are now looking into the possibility that red lights might slow the development of this condition.

For the new study, researchers from the Australian National University in Canberra, along with other centers, followed 264 children aged 3 to 16 years with myopia, who were asked to use ‘binoculars’ ‘ red light at home twice a day for three minutes, five days. a week.

The device, which they tried for a year, was connected to the Internet, so the researchers could check if the kids were using it.

The Journal of Ophthalmology reported that after 12 months, the proportion of children’s eyeballs changing shape was reduced by more than two-thirds compared with children with myopia who were not treated with red lights.

Red light has the longest wavelength of the primary colors – 650 nanometers – and is thought to be able to penetrate body tissue better.

One theory is that it slows the development of myopia by stimulating the retina to release more dopamine.

Another approach might be to increase the natural light children are exposed to in classrooms, as new research shows that those taught in sunny classrooms may be less likely to be nearsighted.

When ophthalmologists compared the progression of nearsightedness in 300 children in the highest and lowest sun exposure classes over six months, the condition was worse in those with the lowest levels of sun exposure. study with low light levels.

Writing in the Korean Journal of Ophthalmology, the scientists suggested that allowing more sunlight into classrooms could ‘protect against myopia’. This may be because sunlight triggers more dopamine production.

Commenting on the Australian study, Gwyn Williams, consultant ophthalmologist at Singleton Hospital in Swansea, said there was ‘strong evidence’ that too much screen time indoors is a contributing factor. myopic.

He added: ‘While this study points to the fact that insufficient natural light exposure is partly to blame, and that exposure to ‘right’ wavelengths indoors may be helpful, It’s important to remember that spending time outdoors has health benefits.

‘More work needs to be done to encourage children to play more outdoors and limit screen time – especially at an early age.’

Air filtration can actually remove viruses like Covid, a research team at Addenbrooke Hospital in Cambridge has found. Highly efficient particulate air (HEPA) filters, which pass air through a fine mesh, have been tested in two Covid zones – no trace of the virus on the days the filters were in use, reported in the journal Clinical Infection Diseases.

Ultra-strong gel can help fix a broken heart

Engineers have developed a ‘living’ gel to heal damaged heart tissue, vocal cords and other tissues that move as they heal.

The move can delay the healing process, which means that the patient needs to be injected with gels – but they can disintegrate. The new water-based material is full of tiny holes that tissue cells can grow through, making it naturally stronger.

Scientists at McGill University in Canada compared the material’s strength to other gels, using intense vibrations to simulate the human vocal cords. The journal Advanced Science reports that other gels have broken down while the new gel is still strong.

Vibrating bracelets to ease the pain

Vibrating bracelets may help reduce pain and fatigue in cancer patients.

The Apollo device, like a watch strap, is designed to mimic human touch in order to calm the sympathetic nervous system – responsible for the body’s fight-or-flight response and can increases stress if over-activated.

The £250, battery-powered device was developed by neuroscientists at the University of Pittsburgh in the US

It is currently being tested on 30 breast cancer patients in a trial.

Earlier research showed that wristbands cut stress by up to 40%.

The secret of A-class body

This week: Nicole Scherzinger’s thighs

The singer, 43 – seen here at a Super Bowl party – goes hiking, swimming and yoga according to her Instagram posts. She also runs and does strength training to maintain her sculpted figure.

What you should try: Try the side-impact move to get your inner thighs working. Stand with feet hip-width apart and hands hip-width apart.

Take a big step to the right, push your hips back, and bend your right knee to lower your body until your right knee is bent 90 degrees.

Push back to an upright position, directing your right knee upward toward your chest. Continue for 60 seconds, then repeat on the other side. It’s a set. Repeat four sets and do this move three or four times a week.

Avoid late-night snacking to improve work performance. A study by North Carolina State University in the US found that people who ate unhealthy foods at night were more likely to feel unwell in the morning, with symptoms like headaches and stomach upset. This has affected their work efficiency.

Health status with surprising associations. This Week: Psoriasis and Gout

According to a study published last year in the Journal of the European Institute of Dermatology and Dermatology, based on more than 100,000 people, people with psoriasis had a 60% higher risk of developing gout.

Psoriasis is associated with a problem with the immune system, resulting in the body overproducing skin cells, causing the formation of the characteristic red and rough patches covered with silvery scales.

It is thought that the rapid production of skin cells and the inflammatory process produces uric acid, a compound that builds up in the joints, forming the needle-shaped crystals that cause gout.
