Blue light emitted by devices like smartphones, computers, and televisions is becoming a major factor disrupting our sleep cycles. Research reveals that a significant number of Americans use electronic devices close to bedtime, contributing to poor sleep quality. Reducing exposure to blue light, particularly in the evening, is a simple yet effective way to help your body prepare for restful sleep.

What Is Blue Light?

Blue light is part of the visible light spectrum and is emitted by natural and artificial sources like the sun, fluorescent lights, LED lights, and digital screens. This wavelength is known for influencing our alertness, mood, and sleep patterns. During the day, blue light plays a role in regulating circadian rhythms, helping us stay alert and focused. However, exposure to it in the evening can have a detrimental effect on sleep quality.

How Does Blue Light Impact Circadian Rhythms?

Circadian rhythms are 24-hour cycles that control essential bodily functions, including sleep. Light is the primary factor that aligns these rhythms with day and night. Historically, exposure to sunlight during the day helped set our body clocks, signaling when to be awake and when to sleep. However, the widespread use of artificial lighting and electronic devices has introduced more light exposure after dark, disrupting these natural cycles.

Blue light, in particular, has the strongest impact on circadian rhythms. During daylight hours, blue light helps us feel alert by stimulating the brain, raising body temperature, and increasing heart rate. But in the evening, exposure to blue light can confuse the body’s internal clock, suppressing melatonin—the hormone responsible for making us feel sleepy. As a result, our brains may remain in “daytime mode,” preventing us from winding down for the night.

Health Consequences Of Disrupted Sleep

Persistent disruption of circadian rhythms can lead to a range of health issues, including metabolic disorders, poor mental health, and increased risk for conditions like depression and anxiety. Furthermore, the inability to sleep well at night affects cognitive performance, mood, and overall well-being. Chronic exposure to blue light in the evening may significantly contribute to these negative health outcomes.

Devices That Emit Blue Light

Many common devices in our daily lives emit blue light, including:

- Smartphones and tablets

- Computer monitors and laptops

- Televisions and e-readers

- LED and fluorescent lighting

- Video game consoles

How To Minimize Blue Light Exposure

To reduce the effects of blue light on your sleep, here are some practical strategies:

1. Turn off screens before bed: Try to avoid using electronic devices at least two to three hours before bedtime. Reducing screen time helps prevent blue light from interfering with melatonin production.

2. Adjust your lighting: Dim your home’s lights or switch to warmer-toned lighting in the evening. You can also use lamps with red or orange light, which are less likely to impact your circadian rhythms.

3. Night mode settings: Many smartphones and computers have a "night mode" feature that reduces blue light emission. Make use of these features to limit exposure in the hours leading up to bedtime.

4. Blue light-blocking glasses: Special glasses designed to filter out blue light may be helpful for some individuals. These glasses can block or reduce the melatonin-suppressing effects of blue light.

5. Apps for blue light reduction: There are several smartphone and computer apps available that reduce blue light emission, allowing you to use your devices before bed without disturbing your sleep.

6. Create a sleep-friendly environment: If you can’t control light sources in your bedroom, consider using an eye mask to block out ambient light and promote better sleep.

Health officials are urging people to seek immediate medical help if they notice three particular symptoms appearing alongside Covid, as these could signal a more serious infection.

According to the latest data from the UK Health Security Agency (UKHSA), Covid cases have dipped slightly but remain present at “low levels” across the country. Hospital admissions have also fallen modestly, with weekly test positivity dropping to 10.3 percent from 11.9 percent the week before.

Despite the decline, people aged 85 and older continue to face the greatest risk of being hospitalised with the virus. Experts stress that identifying certain warning symptoms early can be key to preventing complications and ensuring timely treatment.

3 Covid Symptoms That Are Major Warning

People are being urged to seek urgent medical advice if they or their child develop three specific symptoms while infected with Covid, as it may point to a more serious illness.

Health experts recommend contacting a GP or calling for medical assistance if symptoms such as a rash, loss of appetite, or unusual weakness appear. Immediate help is also advised if a high temperature of 38°C or above lasts for five days or fails to reduce with paracetamol.

Medical attention is further encouraged if symptoms worsen, show no improvement, or if you are unsure how to manage them. For infants, extra caution is necessary as any baby under three months old with a temperature of 38°C or higher, or a child aged three to six months with a temperature above 39°C, should be assessed by a healthcare professional.

Covid Booster Shots: Who Can Get Them This Autumn

The eligibility rules for Covid booster vaccines have been updated for the current autumn rollout. While earlier boosters were offered to people aged 65 and above and those with certain long-term conditions, this year’s criteria have been made more specific.

Those eligible for the latest booster include:

• Adults aged 75 and over, including anyone who will turn 75 by January 31, 2026
• Individuals aged six months to 74 years with a weakened immune system due to illness or medical treatment
• Residents of care homes for older adults
• Health officials continue to encourage eligible groups to stay up to date with vaccinations, especially heading into the winter season, when respiratory infections tend to rise.

COVID-19 Variant Stratus: What You Should Know

A new COVID-19 strain known as Stratus, officially labeled XFG, has begun to circulate globally. First identified in Southeast Asia in January 2025, the variant quickly spread across 38 countries by mid-year. The World Health Organization (WHO) has classified Stratus as a “variant under monitoring,” meaning it is being closely studied to understand its transmission rate, symptom pattern, and potential health impact.

Frankenstein Variant: Common Symptoms of Stratus

For most people, especially those who are vaccinated or boosted, Stratus infections appear to be mild to moderate. Still, recognising its symptoms early remains important.

The most common signs include:

• Persistent dry cough
• Tiredness or fatigue
• Fever
• Other possible symptoms:
• Shortness of breath or chest tightness
• Sore or scratchy throat
• Headache and body aches
• Upset stomach, nausea, or loss of appetite
• Loss of taste or smell (now less frequent)
• Brain fog or difficulty concentrating

If you notice these symptoms, monitor your condition closely and contact a healthcare provider if they worsen or persist. Vaccination and booster doses remain key to reducing the severity of illness and preventing complications.

Atorvastatin Recall 2025: Statins have long been the first-line treatment for high cholesterol, but the Food and Drug Administration (FDA) has confirmed a nationwide recall of over 140,000 bottles of a cholesterol-lowering medication. Officials flagged that some pills may not dissolve properly after ingestion, potentially reducing effectiveness for patients who rely on them daily.

The recall affects Atorvastatin Calcium, the generic version of Lipitor, which is taken by roughly 39 million Americans, most of them adults over 40, according to Dr. Tamanna Singh of the Cleveland Clinic. Federal records show that the recalled batches were manufactured by Alkem Laboratories and distributed by Ascend Laboratories in New Jersey. The FDA’s September 19 enforcement report found that several batches failed quality tests designed to ensure proper dissolution of the pills.

If the pills dissolve inconsistently or more slowly than intended, the medication may not deliver the expected cholesterol-lowering effect. The FDA classified the recall as a Class II action, indicating moderate concern. While temporary or reversible side effects could occur, the likelihood of serious harm is low.

Atorvastatin Recall: Which Atorvastatin Tablets Are Affected

The recall covers multiple strengths and bottle sizes of Atorvastatin Calcium Tablets, which are among the most commonly prescribed statins globally. Affected formulations include:

• 10 mg – 90, 500, and 1,000 tablets per bottle
• 20 mg – 90, 500, and 1,000 tablets per bottle
• 40 mg – 90, 500, and 1,000 tablets per bottle
• 80 mg – 90 and 500 tablets per bottle

Most recalled batches have expiration dates between July 2026 and February 2027.

Cholesterol Medication Recalled: Safe Alternatives to Atorvastatin

If you are affected by the recall, there are several alternatives to help manage cholesterol levels effectively:

1. Ezetimibe (Zetia)

Ezetimibe is often recommended when a statin alone doesn’t sufficiently lower cholesterol. It may be used if you are on the maximum statin dose but your cholesterol remains high, or alongside statins such as atorvastatin or simvastatin for conditions like homozygous familial hypercholesterolemia.

Ezetimibe works by blocking cholesterol absorption in the small intestine, causing the body to use up more cholesterol from the blood. It is one of the few non-statin medications that can further reduce LDL cholesterol, either alone or combined with statins or other alternatives.

2. Fibrates (e.g., gemfibrozil, fenofibrate)

Fibrates mainly target high triglyceride levels, a type of fat in the blood linked to heart disease and pancreatitis, and can also mildly lower LDL cholesterol. They can be taken alone, with ezetimibe, or with a statin. However, combining gemfibrozil with a statin may increase side effects, so caution is advised.

3. Bile Acid Sequestrants (e.g., cholestyramine, colestipol, colesevelam)

Bile acid sequestrants lower cholesterol by binding bile acids in the intestine, preventing their reabsorption. The liver then uses more cholesterol from the blood to produce new bile acids, reducing LDL cholesterol.

Potential drawbacks include:

• Multiple pills per day may be needed
• Possible interactions with other medications or vitamins, which can reduce effectiveness
• May increase triglyceride levels
• Can cause constipation or stomach upset

Imagine sitting down to a juicy, perfectly cooked steak on a warm evening, and hours later you’re hit with terrible stomach cramps, itchy hives, and swelling so bad you might need to rush to the ER. The weird part? It’s not food poisoning, and the steak wasn’t bad. What’s actually happening is your own immune system is reacting, because of a tiny tick bite you got weeks or even months ago, one you probably don’t even remember.

What Is Alpha Gal Syndrome?

Alpha-gal syndrome is a food allergy that can develop after a tick bite, leading to allergic reactions to red meat and products made from it. While several types of ticks can trigger it, the lone star tick is the most common culprit. Not everyone who gets bitten will develop the allergy, but repeated bites can increase the risk or worsen symptoms, as per Cleveland Clinic.

What Can Trigger an Alpha-gal Reaction?

You may have an allergic reaction to:

• Meat from mammals, such as beef, pork, or lamb
• Foods or products made with animal fat
• Certain medications
• Cow’s milk and dairy products

Alpha-gal is a sugar molecule found in most mammals (except humans) and in tick saliva. Not everyone who is bitten by a tick develops alpha-gal syndrome, and you might not react to every food or product that contains it.

Symptoms of Alpha-gal Syndrome

Alpha-gal syndrome can cause reactions ranging from mild to life-threatening. Common symptoms include:

• Skin changes, like itching, hives, or flushing
• Swelling of lips, eyelids, throat, tongue, or face (angioedema)
• Respiratory issues, such as cough, shortness of breath, or wheezing
• Digestive problems, including stomach pain, diarrhea, heartburn, nausea, or vomiting
• Dizziness or fainting
• Joint pain

Some people may experience only skin or digestive symptoms, while others may have multiple symptoms at once. In severe cases, alpha-gal can trigger anaphylaxis, which can make breathing difficult, cause a dangerous drop in blood pressure, and even be fatal. Call 911 or go to the ER immediately if severe symptoms appear.

Timing of Symptoms

Unlike most food allergies, reactions to alpha-gal can occur two to six hours after eating meat or dairy. Medications containing alpha-gal may trigger a faster reaction.

Causes of Alpha-gal Syndrome

Alpha-gal syndrome develops after a tick bite, most commonly from the lone star tick, though bites from black-legged (deer) ticks and other species can also cause it. Ticks carry alpha-gal molecules in their saliva, and exposure during a bite can make your immune system recognize alpha-gal as a threat, triggering an allergy.

Experts aren’t certain why some people develop the allergy while others do not. Repeated tick bites can worsen symptoms or make reactions more frequent.

What Is Lone Star Tick?

The lone star tick is a tiny bug, sometimes as small as a poppy seed. Adult female lone star ticks are easy to identify by the white dot on their backs, the “lone star.” They are commonly found in and around wooded areas across the Midwestern and Eastern United States.

Having alpha-gal syndrome is not just about giving up burgers or steaks. Like other food allergies, it can affect a range of products you may need to avoid. While caution is important, most people with AGS won’t react to every item that contains alpha-gal, and for some, symptoms may improve within a few years. Your healthcare provider can guide you on which foods to steer clear of and what to expect in your individual case.
