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.

After a long day at work, the occasional glass of wine helps many people unwind. However, some struggle to strike a balance and get involved in binge drinking habits. If you are someone who is unable to give up that frequent dose of cocktails, then a study claims that weight loss drugs can come to your rescue. Experts have found that alcoholics who are obese, when given Wegovy, could curb their drinking habits by as much as 70 per cent. A study in Denmark was led by experts from the Mental Health Centre Copenhagen and Frederiksberg Hospital, and experts used semaglutide on 108 obese patients seeking treatment for alcohol use disorder.

Can weight loss drugs help curb drinking habits?

Half the participants in the study were given 2.4 mg of the drug for six months. The other half were also given a dummy drug. Researchers found that people who were on weight loss drugs had fewer days of binge drinking. Furthermore, their alcohol cravings also dipped compared to people on placebo. Before the trial began, participants engaged in binge drinking on an average of 17 days per month.

Researchers also noted that people who were given semaglutide for six months saw their binge drinking days reduce to five in a 30-day period. This correlated to a 40 per cent dip in drinking days in a month, compared to a 26 per cent dip in the placebo group. These dummy drugs helped reduce drinking days to nine. In terms of alcohol quantity, trial participants drank roughly 2,200 g in the 30 days before the trial started. This meant about 154 drinks in a month, or five per day. Over a period of six months after the trial, there was an impressive 70 per cent dip — from an average of 154 drinks a month to 46 drinks a month in people who were taking semaglutide.

What are the benefits of semaglutide?

Alcohol consumption dipped by an impressive 47 per cent in the dummy drug group as well. The study found that overall alcohol consumption can be reduced among semaglutide users compared to people who were taking the placebo. Researchers found that semaglutide not only affects appetite but also influences biological mechanisms associated with addiction.

Independent researchers found that the results were encouraging and strong enough to be used in helping people struggling with alcohol use problems. However, more research is required in this area. Researchers also noted that there were no follow-ups with the participants after the semaglutide treatment ended. This means that experts could not be fully certain whether people reverted to their old drinking habits once they stopped using the medicine.

What are the health benefits of weight loss drugs?

Apart from inducing weight loss, weight loss drugs have the following health benefits:

1. Quitting smoking
2. Can help kick drug habits such as cocaine use
3. Lower risk of heart attack or stroke
4. May help reduce blood pressure and cholesterol to improve heart health
5. Lower risk of dementia

A whopping $600 million global vaccine aid meant for poorer nations has been put on hold by US Health Secretary Robert F. Kennedy Jr., according to a media report.

The delay in vaccines is putting pressure on the international humanitarian group Gavi, the Vaccine Alliance that distributes them, Politico reported.

Gavi noted that it has not received the funds due for the current and previous fiscal years, which account for about 15 percent of its budget.

The funds are set to expire on September 30 if the Trump administration does not release them.

The organization provides vaccines for 20 diseases, including measles, malaria and polio, to more than 50 low-income countries worldwide.

Sania Nishtar, Gavi CEO, told the newswire AFP, the funding gap, combined with reductions from other donors, has particularly impacted malaria vaccination efforts.

Gavi has delivered 39 million doses of a malaria vaccine to 25 African countries, where the disease predominantly affects children under five. Nishtar warned that tens of thousands of children could die as a result of the funding cuts.

Why Is Kennedy Holding Up Vaccines

Kennedy argues that the shots are obsolete with dangerous ingredients that the US has long since phased out.

“Gavi has refused to provide the United States with the specific data, studies, or detailed accounting of how US funds are used,” Emily Hilliard, senior press secretary at the Health and Human Services Department, said in a statement.

Advocates for Gavi, the Vaccine Alliance warn that withholding funds could cost children’s lives. They argue that the vaccines used are safe and better suited for developing regions, where refrigeration is limited and administering booster doses is more difficult.

Hilliard said Gavi has declined to create a plan to phase out thimerosal, a mercury-based vaccine preservative that Kennedy believes may be linked to autism. The administration has asked Gavi to stop using vaccines containing this preservative.

Thimerosal is used in several vaccines distributed by Gavi, including combination shots protecting against multiple diseases, according to former chief executive Seth Berkley. He explained that many developing countries rely on multi-dose vials, which require less refrigeration but may contain thimerosal to prevent contamination.

Without such vaccines, “kids would go without vaccines… and that would lead directly to deaths,” Berkley said.

During testimony before the Senate Appropriations Committee, Kennedy also raised concerns about a vaccine used to protect against diphtheria, tetanus and pertussis, claiming it had been discontinued in the US due to safety issues.

Gavi responded that the vaccine remains in use because it offers longer-lasting protection and requires fewer doses. The organization said the vaccine “is safe and effective and estimated to have saved 40 million lives in the past 50 years,” the report said.

A plant-based diet is highly recommended for a healthy heart — weight watchers can also benefit from it, as can diabetics. When one goes vegan, the biggest change comes when one moves from dairy milk to oat, almond, or soy milk. Parents, too, are now shifting their children to trendy vegan milk options — little do they realise that this could bring their worst fears to life. According to the British Society for Allergy & Clinical Immunology, drinks that are aimed at children and often marketed as healthy are usually loaded with sugar and offer little or no nutrition.

Why has plant milk become a preferred choice?

Experts found that children under five years of age are more prone to malnutrition, tooth decay, or even obesity. The study is the first of its kind, and its warning will be published in the coming week. It is backed by the British Dental Association and the British Dietetic Association. Doctors say that plant-based drinks are often compared to cow’s milk in terms of nutrition. However, these claims are not supported by current evidence.

Why is plant milk discouraged for children?

Plant milk has gained popularity in recent years because of the health benefits that many believe it offers. While adults may benefit from it in several ways, toddlers must not be given these packaged, sugary drinks. The added sugars can become nothing more than a frequent treat for children, who may lose their milk teeth sooner and suffer from decay. Researchers found that families are often convinced that plant milk is good for children, but these oat, almond, and soy versions of milk are processed and full of sucrose and fructose syrups.

According to a report, most of these drinks contain large amounts of sugar in the form of maltodextrin, glucose syrup, sucrose, and fructose. A 350 ml glass of such milk contains more than double a toddler’s daily sugar allowance. Ideally, toddlers should not be given more than 14 grams of sugar every day. Their young bodies can struggle to absorb vitamin B12 and calcium from plant drinks. The BSACI recommends that parents opt for unsweetened, fortified plant milk instead, as these can play a crucial role in supporting children’s health.

How do ultra-processed foods affect children’s health?

Ultra-processed foods (UPFs) are defined as food groups that undergo a great deal of processing — the most natural foods fall under Group 1, while heavily processed foods are placed under Group 4. While these do not definitively determine how healthy a food option is, they indicate the level of processing involved. Highly processed foods are associated with a range of health problems, which is why it is important to make informed dietary choices.
