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.

One of the most debated claims that sunscreen may significantly increase the risk of skin cancer is putting an old study back in focus. We took a closer look at the research and it shows a far more complicated picture than social media noise.

Study On 470,000 Participants

The controversy stems from a 2023 study based on data from more than 470,000 UK Biobank participants.

The research studied how genetic and environmental factors interact to impact the risk of skin cancer. It found that people who used sunscreen frequently had higher observed rates of melanoma, basal cell carcinoma, and cutaneous squamous cell carcinoma.

Compared to people who rarely or never reported using sunscreen, those who always used it had an observed relative risk of about 3.92 for invasive melanoma, 2.40 for basal cell carcinoma, and 2.26 for squamous cell carcinoma.

Can Sunscreen Use Contribute To Risk Of Skin Cancer?

The the crucial part of the study is that it did not establish that sunscreen directly causes skin cancer.

The observational research was primarily designed to investigate gene-environment interactions, not to test whether sunscreen causes skin cancer.

The authors themselves described the sunscreen association as surprising and discussed several possible explanations. One of them is “sunscreen paradox.”

What Is The 'Sunscreen Paradox'?

People who spend more time outdoors, have accumulated more UV exposure, or already have a higher risk of skin cancer may be more likely to use sunscreen in the first place. Sunscreen use can therefore become a marker of higher sun exposure rather than the cause of the cancer.

Lead author Ivan Litvinov told AAP FactCheck that the viral interpretation had misrepresented the findings. “The post misinterpreted the results of our study,” he said.

Litvinov also explained that sunscreen can create a false sense of security when people use too little, fail to reapply it or treat it as permission to stay in the sun longer. This indirectly contributes to the risk of skin cancer. “When sunscreen is used as a ‘permission to tan’, problems arise,” he said.

Should You Stop Using Sunscreen?

Current evidence does not support the conclusion that one must stop using sunscreen to avoid skin cancer.

A randomized trial based on 1,621 adults in Australia found that regular sunscreen use was linked with fewer melanomas over long-term follow-up. Invasive melanoma was substantially lower among those assigned to daily sunscreen use.

More recently, a 2026 review of photoprotection concluded that daily sunscreen use reduces actinic keratoses and cutaneous squamous cell carcinoma in high-risk people, although evidence for basal cell carcinoma and melanoma prevention is more heterogeneous.

How Can You Protect Your Skin Without Using Sunscreen?

While sunscreen is important, one must follow some other steps to ensure complete protection. Here are some tips you should remember according to American Academy of Dermatology Association.

Find Your Shade

The sun's rays are most powerful between 10 a.m. and 2 p.m. During these hours, it's best to seek shade. A good rule of thumb: if your shadow is shorter than you are, the sun is very strong, and you should definitely look for some cover.

Dress For Sun Protection

Whenever you can, wear sun-protective clothing. This means choosing things like a lightweight, long-sleeved shirt, long pants, a wide-brimmed hat, and sunglasses with UV protection.

For even better defense, look for clothing labels that have an Ultraviolet Protection Factor (UPF) number, which tells you how much UV radiation the fabric blocks.

Say No To Tanning Beds

Both the sun and tanning beds give off harmful ultraviolet (UV) light, which can cause skin cancer and wrinkles. It's best to avoid tanning beds completely.

If you want to have a tanned look, consider using a self-tanning product instead, but remember to still use sunscreen along with it for actual sun protection.

Be Extra Careful Near Reflective Surfaces

You need to be especially cautious when you're near water, snow, or sand. These surfaces are highly reflective, meaning they bounce back the sun's damaging rays, which can significantly increase your chance of getting a sunburn.

COVID-19 is surging in some parts of California as wastewater surveillance showing a sharp rise in the amount of virus circulating in the surrounding communities.

The latest data comes as California health officials warn that the state’s COVID-19 pattern appears to be shifting, with summer outbreaks becoming more prominent than winter ones.

According to the California Department of Public Health data cited by the San Francisco Chronicle, COVID-19 outbreak expanded in June, rose through July and continued rising in August. Hospital admissions are also increasing, although they remain relatively low compared to previous outbreaks.

WastewaterSCAN data showed that COVID-19 concentrations across monitored Bay Area sites were 136% higher in July than in June. By early August, nearly 54% of monitored sites were classified as having “high” levels, with San Francisco, San Jose, Sunnyvale, San Rafael, Vallejo and Napa among the communities reporting high levels of cases.

“Monitoring wastewater can act as an early warning system for health officials and the public,” said Amanda Bidwell, WastewaterSCAN’s scientific program manager.

Wastewater Surveillance Reveals COVID-19 Resurgence

Wastewater surveillance looks for traces of SARS-CoV-2 in sewage. Because infected people can shed the virus even when they have mild or no symptoms, wastewater can provide an early picture of infections spreading through a community.

The CDC says wastewater trends can detect viruses earlier than clinical testing and can also capture infections that never result in a doctor's visit. An increase in wastewater viral activity may therefore signal a higher risk of infection in the community.

California is currently one of only four U.S. states where COVID-19 wastewater activity is classified as moderate or high by the CDC, according to the Los Angeles Times. The CDC also says COVID-19 is growing or likely growing in 43 states.

Is A Dangerous New COVID Variant Causing The Surge?

Wastewater monitoring suggests several variants are circulating rather than one strain. In the Bay Area, XFG, also known as “Stratus,” remains prominent, while NB.1.8.1, or “Nimbus,” is also circulating.

Stanford infectious disease expert Dr. Abraar Karan said there is currently no evidence suggesting a dangerous or different virus or a variant that is expected to cause a major increase in hospitalizations or causalties.

Experts say the current wave should not be confused with the severe COVID-19 surges of the pandemic's early years. According to recent data and reports, hospitalizations remain comparatively low compared to previous outbreaks.

However, California health officials are urging people who have not received the 2025-26 COVID-19 vaccine to consider getting it now rather than waiting for the updated vaccine expected later this year.

“Summer is really the bigger peak,” California Public Health Officer Dr. Erica Pan said. “Go ahead and get it now, given the surge.”

The timing could become important as schools reopen and people spend more time in crowded indoor settings. In 2025, California's summer COVID-19 wave peaked later in the season, meaning the current increase may not be over yet.

V, a member of K-pop sensation BTS, has revealed that he has been dealing with hearing loss in one ear for about two and a half years.

V, whose real name is Kim Tae-hyung, opened up about the condition for the first time during a livestream amid the band's highly anticipated world tour.

"If the hearing in my left ear is at 100, it's only about 30 in my right," V said.

The 30-year-old singer said his hearing became worse while he was serving in the military. However, he initially ignored the problem, believing it was "a matter of mental strength," BBC reported.

He said he is now taking medication and visiting the hospital regularly.

V Reveals Risk Of Stress Fracture

V also admitted to pushing through pain during BTS' current tour, revealing that he is dangerously close to developing a stress fracture in his leg.

“My shin is right at the point just before a stress fracture. Even today on stage, my heart was set on running around, but it hurt too much at points and I couldn’t," he was quoted as saying by Channel News Asia.

Doctors have warned him about inflammation and early bone damage.

“It hasn’t reached a stress fracture yet, but there’s a lot of inflammation in my shin, and I think there’s some microdamage to the bone. I’ll be careful with myself so I can finish this tour properly,” he added.

BTS is currently halfway through its massive Arirang world tour, which will stop in Singapore in December and conclude in the Philippines in March 2027.

What Is Hearing Loss?

Hearing loss can happen when any part of the ear is not working in the usual way. This includes:

• The outer ear
• The middle ear
• The inner ear
• The hearing or acoustic nerve
• The auditory system in the brain

Hearing loss is a growing health concern worldwide. According to the WHO, more than 1.5 billion people—nearly 20% of the world's population—live with some degree of hearing loss. Of these, approximately 430 million people have disabling hearing loss requiring rehabilitation.

Hearing loss can have a significant impact on a person's life, affecting education and job prospects.

What Causes Hearing Loss?

Hearing loss can occur at any time during life. Causes can range from genetic factors to conditions such as Down syndrome or Usher syndrome.

Other factors include:

• Maternal infections during pregnancy
• Complications after birth
• Spending five days or more in a neonatal intensive care unit (NICU)
• Severe jaundice requiring a blood transfusion

How To Prevent Hearing Loss

To help prevent hearing loss in adults:

• Limit exposure to loud noises above 85 decibels.
• Wear ear protection, such as foam plugs or earmuffs, around heavy machinery or at concerts.
• Keep personal headphone use at safe volumes.
• Manage chronic health conditions such as high blood pressure.
• Avoid putting objects such as cotton swabs inside the ears.
