Even if you may not be used to it, sunscreens should be a regular part of your skincare routine, especially for the upcoming sunny days. While the sun may feel great after for a while, your skin will suffer damage if exposed to it for too long. It is good to have a stock of sunscreen so that you do not run short of necessary days, however the way you store them could sustain or destroy how effective they are.

Like other skincare and room temperature sensitive products, sunscreen also needs to be stored in a particular space to ensure that the product does not get damaged. In a viral TikTok video, Neal Rimmer, a senior scientific advisor at ‘Which?’, pointed out a big mistake many people make while carrying their sunscreen, especially when they are sunbathing. People usually don't bother keeping it in the bag after they are done using it, which means it lies around in the sun. That is ruining the shelf-life of the product as high temperatures decrease the product quality.

Sunscreen Has a Shelf Life

Just like milk or other products in your house, sunscreen doesn't last forever. Neal pointed out that it's really important to always check the date on your sunscreen bottle. You'll usually find a small symbol that looks like an open jar with a number and a letter next to it, such as '12 M'. This tells you how many months the sunscreen will be effective after you first open the bottle. Even if you haven't used much of it, if it's past this date, it might not protect your skin properly anymore. Using old sunscreen is like using a worn-out shield – it might not keep you as safe as you think. So, make it a habit to check the expiry information on your sunscreen before you use it each time, especially at the start of the sunny season.

You Shouldn’t Just Rely On Sunscreen

Putting on sunscreen is a great way to protect your skin, but it shouldn't be the only thing you rely on. Neal advised that for the best protection, we should use a combination of methods. Think of sunscreen as one layer of defense, and wearing clothes and a hat as extra layers. Clothes can cover up large areas of your skin that you might miss with sunscreen, and a hat can shield your face, ears, and neck, which are often very exposed to the sun.

Also, remember that sunscreen needs to be reapplied regularly – about every two hours – to keep working well. If you're swimming or sweating a lot, you need to put on more sunscreen even more often. Experts also recommend choosing a sunscreen with an SPF of 30 or higher. SPF stands for Sun Protection Factor, and a higher number means more protection from the sun's harmful rays.

The NHS has issued a warning for anyone using a common painkiller, highlighting possible harmful interactions with other medications. Across the UK, many people turn to over-the-counter medicines for daily aches, colds, and minor illnesses. Among these, paracetamol is one of the most widely used, often taken for headaches, back pain, and cold symptoms. But, like any medication, it carries certain risks.

Who Should Be Careful?

The NHS has provided guidance on using paracetamol safely, including which drug combinations should be avoided. “Paracetamol is not suitable for some people,” the health body explains. This includes individuals who take warfarin, a drug that prevents blood clots. If you are on warfarin, you should check with your GP before taking paracetamol, the NHS advises. “Paracetamol can raise the risk of bleeding in those who regularly take warfarin.”

Safe Dosing Guidelines

Small doses of paracetamol alongside warfarin are generally considered safe. The NHS adds: “It’s safe to take paracetamol if you’re on warfarin. Stick to the lowest dose that relieves your pain. Exceeding four 500mg tablets in 24 hours for more than a few days can slow your blood clotting, putting you at risk of bleeding.”

Avoid Double Dosing

Combining paracetamol with other medicines containing the same ingredient—like co-codamol or some cold and flu remedies—can be risky due to the danger of overdose. Other common painkillers, such as ibuprofen, aspirin, or codeine, do not contain paracetamol and can safely be taken at the same time.

Check with Your Doctor

The NHS advises consulting a doctor before taking paracetamol if you’re on medications for epilepsy or tuberculosis (TB), as these combinations can also pose risks.

Herbal Remedies and Supplements

Generally, paracetamol is not affected by herbal supplements, though the NHS notes: “There isn’t enough information to say whether herbal remedies, complementary medicines, or supplements are safe with paracetamol. They are not tested the same way as prescription or pharmacy medications and may interact differently.” Patients should inform their doctor or pharmacist about any other medicines or supplements they are taking.

Side Effects of Paracetamol

When taken at the recommended dose, paracetamol “very rarely” causes side effects. For a full list, refer to the information leaflet inside the packaging.

Serious Allergic Reactions

In rare cases, a serious allergic reaction (anaphylaxis) can occur. The NHS advises calling 999 immediately if you notice:

• Swelling of lips, mouth, throat, or tongue
• Rapid or labored breathing, wheezing, or a choking sensation
• A tight throat or difficulty swallowing
• Skin, lips, or tongue turning blue, grey, or pale (on darker skin, check palms or soles)
• Sudden confusion, extreme drowsiness, or dizziness
• Fainting and unresponsiveness
• A child appearing limp, floppy, or unresponsive, with difficulty lifting or focusing their head

That sudden, foggy feeling where you can't focus, especially when you're super tired? New research suggests that these moments of zoning out are actually your brain's last-ditch effort to do the important cleaning it normally saves for when you're fast asleep. Your brain is trying to take a quick, emergency break.

We have all had days when focusing seems too difficult and you keep ‘spacing out’. When this happens, you take a moment to regain your composure and get back to what you were doing. While you may think that it is a simple lapse in attention, there is a lot that happens in your brain during this time.

The research, published in the Nature Neuroscience, shows this is the time your brain does its ‘maintenance work’ to ensure maximum functionality.

Why Do We Zone Out?

Scientists at MIT used special scanners to look deep inside the brain while people were trying to concentrate. They discovered that the exact moment someone zoned out, a wave of cerebrospinal fluid (CSF), a clear fluid that surrounds the brain, whooshed out, and then flowed right back in. This movement of fluid looks exactly like the process that happens during deep sleep, when the fluid washes away built-up waste and toxins from the day. When you're awake and tired, your brain is trying to force this cleaning process to happen.

How Does Our Brain Keep Functioning Fluidly?

A leading neuroscientist from the study explained that if you skip sleep, these cleaning waves start happening while you're awake, even though they shouldn't. The problem is that while the fluid is flowing and cleaning, you lose your ability to pay attention. It's a trade-off: your brain tries to clean up, but the price is that you can't focus on what you're doing. It’s almost like your brain is desperately trying to squeeze in a tiny bit of "microsleep" maintenance, which steals your focus.

The researchers had people do tests in the lab twice: once after they were well-rested, and once after they stayed up all night. Unsurprisingly, people performed much worse when they hadn't slept. Critically, the zoning out happened far more often after the all-nighter. When they looked at the brain data, they saw a clear pattern: when people's reaction times slowed down (meaning they were zoning out), the big fluid cleaning waves were always present. This strongly suggests your tired brain is trying to use these quick cycles to restore function, even if it makes you temporarily lose focus.

How Do We Know When We Zone Out?

The research revealed that when people zoned out, not only did the brain fluid move, but other things changed, too. Their breathing and heart rate slowed down, and their pupils got smaller. This makes the scientists suspect that a single, powerful "master switch" in the body controls both your high-level functions (like attention and perception) and these automatic, basic physical processes (like fluid movement and heart rate). The finding suggests that a lack of sleep affects your whole body through one central system.

Recently, we are seeing a rise in ‘grind culture’. People are encouraged to pack their days with work and be as productive as possible to secure future success. However, did you know that chasing this success could come at the cost of your heart's health? Dr. Dmitry Yaranov, MD, a cardiologist, who often shared important health advice and knowledge on Instagram videos, explained posted about how as a practicing healthcare professional, there are many heart facts that he wished his patients knew about.

Things we often perceive as important for our careers can come at the cost of our mental and physical health. By not realizing the value of their health and ignoring their limits, people often stretch themselves too far, which can result in reaching a breaking point.

In a recent video posted with the text, “After treating thousands of patients with heart failure this are the things I wish more people knew before it was too late” in the caption he listed 6 hard facts that most people ignore.

6 Habits That Are Leading You To Heart Failure

In the caption Dr. Yaranov explained that cardiovascular health involves much more than just hitting the gym and eating salads. Your heart health is fundamentally tied to sleep, stress management, environmental factors, access to resources, and even the state of your gut. Fix the foundation, not just the numbers.

Sleep Deprivation is Dangerous

Sleeping only six hours nightly and pushing yourself is a serious threat, not a badge of honor. This chronic sleep loss significantly raises your long-term risk of developing severe conditions like heart failure, having a stroke, or experiencing sudden cardiac death. Your body needs rest to recover.

Air Quality Hardens Arteries

Commuting daily in heavy traffic means breathing exhaust and particulate matter. This consistent exposure to air pollution does more than irritate your lungs; scientific studies confirm it literally hardens your arteries, increasing your risk for major cardiac events over time.

Stress Causes Overload

If you are always stressed and simply "pushing through" without managing the pressure, your body is producing too much cortisol. This hormonal overload leads to persistent high blood pressure and widespread inflammation, key factors that severely damage the cardiovascular system.

Gum Health Impacts Heart Health

Ignoring routine dental care and having gum disease creates chronic infection in your mouth. This persistent gum disease results in more body-wide inflammation, which is directly linked to a significantly higher risk of heart attack and other cardiovascular problems.

Food Access Matters

Even if you have the best intentions to eat well, living where healthy food is hard to find (a food desert) makes it difficult. This lack of access to nutritious options leads to worse cardiac outcomes, proving that environment, not just personal willpower, shapes your health.

Gut Health Affects Vital Signs

The state of your digestive system should not be ignored. The millions of bacteria in your gut microbiome play a critical, unrecognized role in helping your body regulate blood pressure and cholesterol levels. You must consciously feed your gut bacteria the right way.
