When the sun is out after a long winter, every one loves it. But not the people of Canary Islands. Tourists there are being warned about the "unusually high risk" of UV rays this week. The Ministry of Health for this holiday destination has urged both, residents and visitors to take extra precautions and preventative measures to limit the impact of sun exposure over their body and skin.

The Ministry observed Aemet, Spain's national weather agency for the forecast which showed higher than normal UV or ultraviolet radiation levels in the region. It is in this backdrop that everyone in the region are requested to be extra careful when they are out in the sun. UV levels are set to reach 7, which is a 'high risk' in La Palma, El Hierro, La Gomera and Gran Canaria. Other regions like Tenerife, Fuerteventura and Lanzarote are expected to reach a level 6, which is also classed as 'high risk'.

UV Index Explained

As per the World Health Organization (WHO), a UV index is a measure of the level of UV radiation, which ranges from zero upward. The higher the UVI, the greater potential for damage to skin and eye and the less time it takes for harm to occur, notes WHO.

The range 1 to 2 represents a low risk, 2 to 5 is moderate, 6 to 7 is at high risk, 8 to 10 is at very high and anything over 11 is extremely risky for anyone to stay out.

UV radiation levels fluctuate throughout the day, with the highest values occurring during the four-hour period around solar noon. The reported UV Index (UVI) typically reflects this daily peak. Depending on geographic location and the use of daylight saving time, solar noon falls between 12 p.m. and 2 p.m. In some countries, sun protection advisories are issued when UV levels are expected to reach 3 or higher, as exposure at these levels increases the risk of skin damage, making protective measures essential.

What happens to you when you are out in sun for too long?

While sun bathing is good, being out in the sun when the UVI indicates a high or very high risk, may cause you health concerns. It can lead to sunburn, premature skin aging, incresed risk of skin cancer, eye damage and in severe cases, heat related disease.

Sunburn

It is one of the most common skin injury which happens when there is excess exposure to UV radiation from the sun. This happens when the UV radiation directly damages the DNA skin cells. These damaged cells die and shed, this is why people experience peeling after getting a sunburn.

Dehydration

This is also a common occurrence when your body loses too many fluids or electrolytes. It can also interfere with your normal body functions. You may feel dehydrated, especially when you are out in the sun, but not well hydrated. The most common symptoms are dizziness, fatigue and headache on hot days.

Hyponatremia

This is an electrolyte disorder in which your body experiences low sodium in blood. The symptoms could lead to nausea, confusion and even weakness. There are extreme cases when one may have seizures, slip into coma or die.

Heat Exhaustion

This is one of the most common consequence of being out under the hot sun. Dehydration with prolonged heat exposure can lead to heat exhaustion.

Heatstroke

When you are out under the sun and your body's core temperature cross 104°, heatstroke may occur. This is also known as sunstroke. As per the Centers for Disease Control and Prevention (CDC), it causes more than 600 deaths each year in the United States.

As the true number of COVID-19 cases and deaths is believed to be higher than reported, a new study suggests that the actual toll of long COVID may also double than the current estimates.

The research, led by Mass General Brigham, found that many long COVID cases remain hidden because current surveillance systems rely heavily on diagnostic codes that fail to capture a large number of patients.

Using a novel AI algorithm, researchers analyzed medical records of nearly 460,000 COVID-19 patients across 58 hospitals in the United States. The findings showed that approximately one in six people — around 16 per cent — developed long COVID, translating to more than 18 million Americans.

The figures are nearly double current estimates and highlight the growing burden of chronic health conditions following COVID-19 infection. The study was published in JAMA Network Open.

“Over 10 million people with long COVID would go entirely undetected by the diagnostic code that health systems and policymakers rely on to track the disease burden,” said corresponding author Hossein Estiri, a faculty member in the Mass General Brigham Department of Medicine.

“The figures we uncovered are almost certainly an undercount,” he added.

Researchers noted that current diagnostic coding systems, including the ICD code U09.9 for post-COVID conditions, identify fewer than 7 per cent of long COVID patients.

What Did The Study Find?

The study analyzed electronic health records from 457,950 patients who had previously tested positive for COVID-19 across four US regions — New England, Southeast Texas, Southern California and Western Pennsylvania.

Overall, 16.3 per cent of patients were identified with long COVID, with regional rates ranging from 13.6 per cent to 22.7 per cent.

The researchers also found significant regional differences in long COVID symptoms and related conditions, including varying rates of prediabetes, which is emerging as a possible long-term effect of COVID-19.

The study authors noted that undocumented infections — which became more common after widespread testing declined — were not included in the analysis. Patients without long-term medical records were also excluded, suggesting the actual burden of long COVID could be even higher.

“These patients are not absent from clinical care; they are absent from the diagnostic code that would identify them as long COVID patients,” said lead author Jiazi Tian, a data scientist in the Clinical Augmented Intelligence Group at Mass General Brigham.

“The cardiologist seeing new dysautonomia, the endocrinologist seeing new metabolic disease, the neurologist seeing unexplained cognitive complaints — some of these presentations are long COVID arriving without the label that would connect them to a COVID-19 infection,” Tian added.

Long COVID refers to symptoms that continue for three months or longer after the initial COVID-19 infection.

Common symptoms include:

• Fatigue
• Brain fog
• Headaches
• Breathlessness
• Altered sense of smell or taste

Researchers say many long COVID conditions are still being studied, and some people may experience multiple symptoms at the same time.

The birth rate in England and Wales has been plummeting continuously over the past few years. In 2025, the same trend continued for the fourth year in a row as the birth rate in the island nation had dropped. The Office for National Statistics (ONS) has reported that the birth rate is at its lowest in the last 50 years.

Though this downward birth rate trend is not a recent occurrence, as it was in 2010 when it started to steadily decline. In 2025, the United Kingdom had 585,000 live births, which was 10,000 fewer than the year before and the lowest overall figure since 1977.

The estimated number of children born per woman also fell under 1.4 for England and Wales in 2025, down from 1.9 in 2010. Along with this decline, women are also marrying later at 29.6 years of age. This is about two years older than it was in 2010, when the fall birth rate began.

Other than this huge dip in birth rate, most notably, 4 in 10 children born since 2010 have at least one foreign-born parent, while in 2010 it was 30 percent.

Is the United States In The Same Downward Spiral?

The US is facing a long-term decline in birth rates. The US Centers for Disease Control and Prevention (CDC) reported that more than 3.6 million babies were born in 2024. This is just a 1% increase from the previous year, which had been the lowest record in births. While this uptick may seem encouraging, it is not enough to reverse the troubling trend.

The US fertility rate remains around 1.6 births per woman. This is significantly below the 2.1 births required to sustain the population growth without immigration.

As per the demographers, this continuous drop began during the Great Recession in 2007. It has continued steadily since.

One of the biggest shifts is the steep decline in teen births. In 1991, about 62 of every 1,000 teenage girls had a child. This number has now fallen to just under 13 by 2024. This is a historic low that reflects a positive shift, better education, access to contraception, and changing attitudes about early parenthood.

A similar trend is seen among women in their 20s, as the rates there, too, have dropped. In 2007, about 106 of every 1,000 women aged 20 to 24 gave birth. By 2024, the number has dropped to around 57. For women aged 25 to 29, the rate fell from 118 in every 1,000 women in 2007 to 91 in 2024.

US President Donald Trump this week underwent his third annual medical check-up during his second term and declared that it went “perfectly well”.

Trump, who turns 80 next month, visited the Walter Reed National Military Medical Center for a routine health examination on May 26. The medical check-up, conducted after about 13 months, reportedly lasted around 3.5 hours.

“Everything checked out PERFECTLY,” Trump wrote on social media.

However, neither Trump nor the White House has disclosed detailed medical findings, leading to renewed speculation about the health of the oldest American President.

The concerns come amid visible signs of deterioration observed during several public appearances. These include persistent bruising on his hands, micro naps during public meetings, slurred speech, and frequent factual mix-ups — all of which have raised questions about whether information regarding his health is being withheld.

The White House had earlier explained that the bruises on Trump’s hands were caused by “frequent handshaking” combined with aspirin use.

Trump Link His Conditions To Stroke

Doctors have also speculated that his slurred speech may indicate signs of a recent stroke.

Dr. Bruce Davidson, a professor at Washington State University’s Elson S. Floyd College of Medicine, discussed the issue during an appearance on The Daily Beast podcast. He said his interpretation was based on observing Trump’s physical behavior and speech patterns over time.

“Earlier in the year, there was video of him shuffling, and I thought that was weird,” he said on the podcast.

He suggested that such movement patterns can sometimes be seen in patients recovering from strokes.

Despite the speculation, Trump has continued to defend his mental sharpness and cognitive abilities.

“So I’ve taken (a cognitive test), and I’ve aced it all three times, I’ll tell you, because it is a positive thing,” Trump said. “It starts off with an easy question. And by the time you get to the middle, it gets tougher.”

Previous Medical Reports Declared Him Healthy

According to a White House summary of Trump’s previous annual medical examination in April last year, he was found to be in “excellent cognitive and physical health”.

“A comprehensive neurological examination revealed no abnormalities in his mental status, cranial nerves, motor and sensory functions, reflexes, gait, and balance. Cognitive function, assessed using the Montreal Cognitive Assessment (MoCA), was normal with a score of 30 out of 30,” White House physician Captain Sean Barbabella wrote.

There were also tests for depression and anxiety, and Trump recorded scores “within the normal range for both,” although exact numbers were not disclosed.

Scans conducted in October also reportedly showed that Trump was in “excellent overall health”.
