**Melatonin and Heart Failure: Correlation, Not Causation**

by Dr. Michael Lee – Health Editor November 19, 2025
written by Dr. Michael Lee – Health Editor

Melatonin Use Linked​ to Increased Heart failure Risk, Study Finds

A new study suggests a meaningful link⁢ between‍ melatonin use and an ‌increased risk of⁣ heart failure, with a reported 90 percent higher chance of developing the​ condition among those taking the supplement. Though,‌ researchers emphasize the findings demonstrate a ⁢correlation, not a ⁤direct causal relationship.

“The message‌ is ​not that melatonin is hazardous, but that we should ⁤not⁤ assume that somthing is completely risk-free just because it is natural or⁤ sold without‍ a prescription,” explained lead researcher Ekenedilichukwu ​Nnadi in an interview with⁤ The Washington​ Post.

The ​study, which has yet ⁢to be peer-reviewed, ⁣focused on individuals who received melatonin⁣ via ⁤prescription.⁢ This‍ presents a limitation, as‍ melatonin is ⁤widely ⁢available over-the-counter in many countries, ⁤making it‍ difficult to determine the extent of overall⁣ usage.‍

Sleep scientist Akinbolaji Akingbola notes the need for further examination. “One‍ needs to carry out randomized studies, ⁤were‍ the participants receive either melatonin‌ or a placebo⁣ at random, in order to get a more reliable‍ result,” he stated. ​

Experts also caution that underlying sleep problems themselves can contribute to heart ⁢issues, self-reliant of melatonin use.The research underscores ​the importance of consulting with a healthcare professional before starting any new supplement regimen.

Viagra Could Reverse Hearing Loss, New Study Finds

Viagra Ingredient Shows Promise in Reversing Congenital Hearing Loss, Study Finds

New York, NY – Sildenafil, the active ingredient in Viagra and other erectile dysfunction medications, may offer a novel treatment for a specific type of congenital hearing loss, according to a new study.Researchers found that sildenafil, along with an arginine supplement, improved auditory detection in fruit flies with mutations affecting the CPD gene – a gene crucial for maintaining healthy hearing.

The findings, published recently, offer a potential therapeutic avenue for individuals born with sensorineural hearing loss caused by disruptions in the CPD gene pathway. This pathway is responsible for maintaining levels of the amino acid arginine, which produces nitric oxide, essential for transmitting signals through the nervous system. When the pathway is disrupted, oxidative stress and cell death occur in the ear hair cells responsible for hearing and balance, leading to sound wave detection impairment.

The study, led by Dr. Shaohua Zhai, focused on fruit flies with CPD mutations. Researchers tested two treatments: sildenafil to stimulate nitric oxide production and a direct arginine supplement. Both interventions demonstrably improved hearing loss in the flies.

“It turns out that CPD maintains the level of arginine in the hair cells to allow a swift signaling cascade by generating nitric oxide,” Zhai explained. “These hair cells in particular are more sensitive or vulnerable to the loss of CPD.”

Sensorineural hearing loss, which affects millions, is typically managed with hearing aids and cochlear implants. However, this research suggests a potential for a curative approach. “We found a promising therapeutic avenue for these patients,” Zhai stated. “It is a good example of our efforts to repurpose FDA-approved drugs for treating rare diseases.”

The study authors emphasize that while promising, these results are preliminary and further research is needed to determine the efficacy and safety of sildenafil and arginine supplementation in humans with CPD-related hearing loss.

Cuba: Dengue and Chikungunya Cases Rise Amid Mosquito Infestation

by Dr. Michael Lee – Health Editor November 18, 2025
written by Dr. Michael Lee – Health Editor

Cuba Faces Renewed Arbovirus Surge Amidst mosquito Infestation⁣ & Resource Challenges

HAVANA – Cuba is ⁤experiencing‌ a significant resurgence of ⁢arboviral⁣ diseases – dengue and chikungunya – fueled by a “very ⁣high” infestation of Aedes aegypti mosquitoes and compounded‍ by⁤ ongoing‍ supply⁤ shortages and sanitation issues, health‍ officials warn. The outbreak is placing a particular strain⁣ on ‌vulnerable populations, including children ⁣and pregnant women.

The ‍escalating ​situation comes as the country grapples wiht the ⁢aftermath of Hurricane Melissa, wich exacerbated existing water supply problems in several⁢ provinces. ‍These disruptions are leading ⁤to increased reliance on ‌home water storage, creating breeding grounds for mosquitoes alongside deficiencies in waste management and sanitation. As​ of last week, authorities reported 21,681 accumulated cases of chikungunya. Data from the Pan American⁢ Health ⁤Organization ​(PAHO) indicates 9,602 ‌confirmed dengue‍ cases,⁤ representing an ‌incidence rate of 87.79 cases per 100,000 inhabitants. The Ministry of Health estimates that ⁣approximately 30% of‍ the Cuban population has been infected with​ either dengue ⁣or chikungunya‌ during this outbreak.

“It is⁣ key to keep ⁢children ‌hydrated, since gastrointestinal ​symptoms can cause hazardous dehydration,” cautioned Montesino Felipe, highlighting the critical​ need for basic ⁢preventative care. The challenge⁤ lies in​ securing adequate supplies amidst‍ the⁣ current logistical difficulties. María Guadalupe Guzmán Tirado, director of the ⁣Research,‍ Diagnostic and Reference Center of the Pedro Kourí‍ Institute (IPK), emphasized the risk posed by the proliferation ⁤of water tanks combined with “inadequate management of solid waste and deficiencies in sanitation.”

Pregnant women are also identified as a high-risk group, requiring ‌urgent hospitalization for diagnosis‌ and treatment,⁢ especially those with pre-existing ⁣conditions like hypertension ⁤or ​diabetes. “You can’t make a diagnosis at home. That has to be done by the hospital,” stated Diana Couto Núñez, president‌ of ‌the Cuban Society of Gynecology⁣ and Obstetrics, warning of possibly serious complications.

The situation underscores the ongoing public health challenges facing Cuba, where access to resources‍ and adequate sanitation remain critical factors in controlling the spread of mosquito-borne illnesses. ‍Further data and‍ analysis ⁤on dengue are available from the Pan American health Organization and previous⁤ reporting on the outbreak can be found here.

If you’re suffering hair loss or premature ageing, low vitamin D may be to blame. Now a top scientist reveals which supplements really will give you a boost – and which are a waste of money

Vitamin D Deficiency Linked to Hair Loss and Ageing: Scientist Rates popular Supplements

Suffering from unexplained hair loss or noticing premature signs of ageing? A growing body of research suggests low vitamin D levels could be a key culprit. Now, a leading scientist has assessed a range of popular vitamin D supplements, revealing which ones offer a genuine boost and which are simply a waste of money.

Vitamin D is crucial for overall health, playing a vital role in immune function, bone health, and potentially, maintaining youthful vitality. With many experiencing deficiencies, notably during winter months or with limited sun exposure, supplementation is often considered. But navigating the market can be confusing.This assessment cuts through the noise, providing a fact-based guide to effective vitamin D supplementation.

POWDERED VITAMIN D

M&S Vitamin D3 Powder, £5.73 for one month’s supply

PRICE PER DAY: 19p.

EXPERT VERDICT: At 50mcg (2,000 IU) per dose, this is still under the 100mcg safe limit and contains easy-to-absorb vitamin D3. Powder could be an easier option if you don’t like taking pills, as it can be added to cereal or smoothies. But at £5.73 for just one month’s supply, it is pricey. It also contains erythritol, a sweetener that may cause stomach cramps, diarrhoea and bloating in some people. 5/10

ENRICHED MUSHROOMS

M&S Baby Chestnut Mushrooms, £1.45 for 200g

PRICE PER DAY: £1.45.

EXPERT VERDICT: These are said to be ‘naturally enriched with vitamin D’ by light exposure. When mushrooms are exposed to UV light, they produce vitamin D2, the version that’s less well absorbed. And mushrooms alone are not enough to maintain optimum vitamin D levels.You’d need to consume at least 200g – a whole pack – every day to get the 10mcg minimum. 6/10

FIZZY TABLETS

Holland & Barrett Vitamin D 1,000 IU/25mcg, £4.49 for 20 effervescent tablets

PRICE PER DAY: 22p.

EXPERT VERDICT: These contain the better absorbed vitamin D3. But as with all effervescent tablets the bubbles are created by adding sodium carbonate – basically salt, so not great for people on low-sodium diets, such as those with high blood pressure. They also contain the artificial sweetener sorbitol, which can cause stomach cramps and diarrhoea; and sucralose, which triggers bloating in some. And they’re quite pricey.4/10

Long-Term Melatonin Use Linked to Increased Heart Failure Risk

by Dr. Michael Lee – Health Editor November 18, 2025
written by Dr. Michael Lee – Health Editor

Long-Term Melatonin Use Linked to Increased Health Risks

Melatonin, a hormone naturally produced by the pineal gland, ‌plays a crucial role ⁤in regulating the body’s internal clock, or circadian rhythm,⁤ and⁣ promoting healthy sleep-wake‌ cycles. ​Production naturally increases as daylight fades, signaling the ⁣body to ‌prepare for rest.

Driven by the desire ⁣to improve sleep, manny individuals turn to dietary supplements containing synthetic melatonin, hoping to boost levels and encourage‌ sleep. While frequently⁣ enough perceived as harmless, recent research⁣ suggests caution might potentially be warranted.

Despite a 2018 report from the French National Health Security Agency (ANSES) indicating that “problems‍ are rare and melatonin is generally considered to pose little risk,” new findings presented at the 2025 American heart Association congress paint a different picture.

Researchers‍ at SUNY Downstate Health Sciences university in Brooklyn analyzed the medical records of over⁤ 130,000 adults experiencing insomnia ‌over a five-year period. The analysis revealed significant differences between those who used melatonin supplements ‌for at ​least one‌ year and those who did‌ not. ⁣ Melatonin users exhibited:

* A 90% higher risk of developing heart failure over five‍ years.
* ⁣ A 3.5 times greater likelihood of hospitalization due to heart failure.
* Nearly​ double the risk of mortality from all ‍causes.

Not a Long-Term Solution

“Melatonin supplements may not be as harmless as ‍commonly assumed,”⁣ cautioned Dr. Ekenedilichukwu ‍Nnadi, the lead author of the study.

marie-Pierre st-Onge, director of the ⁢Center of Excellence for Research on Sleep and​ Circadian Rhythms at Columbia⁤ University (New York), echoed this concern.”I⁣ am surprised that ⁣doctors prescribe melatonin‌ for insomnia and that patients use it year-round, as melatonin ‌is not currently approved ⁣for insomnia treatment ⁣in the United States.” ⁢ She emphasized that, ⁣like in France, melatonin is readily ⁤available as a food supplement in the US, but chronic use should ‌onyl occur under appropriate medical guidance.

Vital Note: This research demonstrates a ⁣ correlation between melatonin‍ use and increased cardiovascular risks – a statistical link exists between the two. Further ​examination is necessary to⁣ determine if a ​direct cause-and-effect relationship ⁣exists.
