For a country that treats 23 degrees Celsius like it is the Sahara, the UK isn’t exactly built for this kind of heat. While most of us are busy Instagramming sunsets, our bodies might be quietly waving red flags. And that tiredness or weird headache is not just the heat; it could be your system slowly giving signs.

Here is what the heat could actually be doing to you and why you should not ignore it.

That Headache Is a Heat Alarm

You’ve drunk your water, you're not hungover, and yet your head’s pounding like you’ve been at a rock concert. Heat headaches are real, and they’re one of the first signs your body is overheating. So slam a glass of water, sit in front of a fan, and maybe ditch the hot coffee for something icy. It would help if you stuck your feet in a cold bucket like your gran used to do.

Sweat, Then No Sweat? That’s Trouble

At first, you’re drenched like you’ve run a marathon in your own kitchen. But then… nothing. You stop sweating. Your skin feels dry, hot and honestly a bit different. This switch can be dangerous. It’s a classic heatstroke sign. Do not ignore if you’ve been roasting all day and your skin is suddenly dry and flushed; that’s your cue to cool down fast. Think cold compress, wet towel, or even lying in a bath.

Muscles Twitching on Their Own?

Random leg twitches? Sudden tummy cramps while lying down doing absolutely nothing? That’s not just your body being weird; it’s heat cramps. They happen when you’re low on salt and hydration, and they can be surprisingly painful. DIY remedy: Bananas, electrolyte sachets, or if you’re fancy, coconut water.

Feeling Like You're About to Faint on the Road?

Heat dizziness is uncertain. One minute you’re grabbing grapes; the next you’re gripping the trolley like it’s your last hope. When it’s hot, your blood pressure can drop faster than your motivation on a Monday. If you suddenly feel woozy or like you’re in a bad dream, sit down before you fall down. Always carry a water bottle.

Can’t Think Straight? Not Just the Heat Making You Dull

If you’re suddenly mixing up names, forgetting simple words, or spacing out mid-text, that could be the heat messing with your brain. Mental fog, confusion, or even irritability are signs that your body is cooking from the inside. If someone is slurring, looking spaced out, or acting like they’ve had a few too many but haven’t, it could be heatstroke. Call for help.

Your Skin Feels Like a Radiator?

Hot, dry, and suspiciously flushed skin is not the summer glow you think it is. If your skin starts feeling like it belongs in an oven, it means your body’s not coping well with the heat. Especially if your pulse is racing and you feel weirdly calm. Get help. This is your body in SOS mode. Cool off immediately and don’t try to “push through it”.

Swollen Feet?

Heat can make your feet and ankles puff up like inflatable pool toys. It’s not you gaining sudden water weight; it’s literally your blood vessels acting up. So put your feet up, wear comfy shoes, and avoid salty snacks. That means no crisp binge while complaining about the weather.

Do Not Forget To:

• Hydrate well
• Draw the curtains always
• Sit in front of a fan for relief
• Avoid peak sun hours
• Don’t ignore what your body’s whispering

Weight loss drugs have become wildly popular in the recent years. However, even though they are popularly known as weight loss drugs they are actually used for a separate purpose, weight loss is just a side effect of the medication.

Medications like Ozempic and Zepbound, which are primarily used to treat type 2 diabetes and help with weight loss, are showing exciting new potential. They might also be helpful for a wider range of health conditions, from sleep apnea to chronic kidney disease.

Diabetes and Weight Loss Medicines

A recent study published in the JAMA Network Open suggests that these kinds of medications, known as GLP-1 receptor agonists, could offer important protection beyond their usual uses. For people who have both obesity and type 2 diabetes, these drugs might lower their risk of death and reduce the chances of developing two serious brain problems: dementia and a common type of stroke.

The findings suggest that GLP-1 drugs could do more than just control blood sugar, help with weight loss, and support heart health; they might also directly protect the brain and its blood vessels.

What the Research Discovered

Scientists had already hinted that GLP-1 drugs might help protect against dementia and stroke. However, there hadn't been many big studies specifically looking at how these drugs affect brain health, especially in people with a high risk, like those who have both type 2 diabetes and obesity.

To help answer these questions, researchers looked at seven years of health information from over 60,000 people. All of these individuals had both type 2 diabetes and obesity. Some of them were taking older diabetes medications, while others were prescribed GLP-1 drugs, like those found in popular medications.

After carefully checking the connections between the medicines and various brain conditions, the scientists found some significant things. People taking a GLP-1 drug had:

• A 37% lower chance of developing dementia.
• A 19% lower chance of having an ischemic stroke, which is the most common kind of stroke, caused by a blocked blood vessel in the brain.
• A 30% lower chance of dying from any cause.

The protection against dementia seemed even stronger for women over 60 and for those with a specific body mass index (BMI) range. An expert noted that people in this group have a particularly good chance to improve their brain health. It's important to know that these GLP-1 drugs did not seem to lower the risk of Parkinson's disease or another type of stroke called hemorrhagic stroke, which happens when there's bleeding in the brain.

Important Things to Consider

This study adds to the growing evidence that GLP-1 receptor agonists are very helpful tools, not just for losing weight and managing diabetes, but possibly for brain health and thinking abilities too.

However, it's really important to understand that this kind of study only shows a link, not that the drug directly causes the protection. It's possible that other things, like people's daily habits, could have played a role in the results, not just the medication itself.

Also, the researchers didn't collect detailed information like blood markers, genetic data, or brain scans. Having this kind of information could give much deeper insights into what's actually happening inside the body. The main researcher emphasized that these findings should be looked at carefully and need to be confirmed by more strict studies before doctors start making official recommendations based on them.

Scientists are investigating whether vitamin D frequently touted for its use in maintaining bone health, could also prevent serious COVID-19 complications. A new study published in the peer-reviewed journal PLOS One illuminates this potential, finding that individuals with vitamin D deficiency were 36% more likely to need hospitalization from COVID-19.

The findings point toward a connection between immune resilience and vitamin D levels, even though the data stops short of proving that supplementation can directly reduce the severity of COVID-19. Still, it’s a significant insight in the ongoing effort to identify who remains vulnerable as the world learns to live with the virus.

“We found people with low vitamin D weren’t necessarily more likely to catch COVID-19,” said lead researcher Kerri Beckmann, a senior research fellow at the University of South Australia. “But if they did get infected, their odds of serious illness and hospitalization were notably higher.”

The study tapped into the vast UK Biobank dataset, analyzing health information from over 150,000 participants. Researchers stratified the data by vitamin D levels and tracked COVID-19 outcomes, including infection rates and hospitalization.

Low levels of vitamin D were not associated with a higher risk of acquiring COVID-19. When infected, however, those lacking vitamin D were much more likely to develop severe illness necessitating hospitalization.

It’s an important distinction. While vitamin D won’t necessarily prevent you from contracting COVID, having adequate levels may improve how your body handles the virus similar to how a vaccine booster might reduce the severity of symptoms.

“Vitamin D plays a key role in regulating the immune system, so it’s plausible that low levels may influence how the body responds to infections,” Beckmann explained.

How Common is Vitamin D Deficiency?

Surprisingly prevalent. Based on a 2022 study appearing in Frontiers in Nutrition, approximately 22% of Americans are deficient in vitamin D. The rate is even greater among some groups, including individuals with darker skin tone, those who reside in the northern latitudes, and those who have restricted sun exposure because of lifestyle or chronic disease.

Vitamin D is sometimes referred to as the "sunshine vitamin" because our bodies produce it by exposing our skin to sunlight. But diet and supplements can also contribute to keeping levels healthy.

Benefits of Vitamin D

The worth of Vitamin D reaches far beyond the COVID-19 pandemic. It's needed for:

Bone health: Vitamin D allows your body to absorb calcium. Without sufficient levels of it, bones become brittle and cause issues such as osteoporosis in adults and rickets in children.

Immune modulation: It assists in modulating innate and adaptive immune reactions — two pillars of your body's defense against disease-causing organisms.

Inflammation regulation: Low blood levels have been associated with higher inflammation, which can lead to worse COVID respiratory outcomes.

And although scientists are hesitant to overhype the value of supplements, it's obvious that having healthy vitamin D levels is part of a larger picture of immune support.

Should You Start Taking Vitamin D Supplements?

Not so fast. Experts, including those involved in the study, stress that while the findings are compelling, they do not confirm that vitamin D supplements alone can prevent hospitalization from COVID-19.

“This is an area worth exploring further, but it’s too early to say supplementation is a silver bullet,” Beckmann noted. “Many people with poor overall health also have low vitamin D levels, which complicates the picture.”

That said, for people at risk of deficiency — including older adults, people with limited sun exposure, and those with darker skin — checking vitamin D levels with a healthcare provider could be a smart step, especially if they’re concerned about COVID outcomes.

How to Boost Your Vitamin D?

There are three main sources of vitamin D:

Sunlight: Just 10 to 30 minutes of mid-day sunlight several times a week may be enough for many people, depending on skin tone, geography, and season.

Diet: Not many foods provide vitamin D naturally. The richest sources from food are fatty fish such as salmon, sardines, mackerel, and trout; egg yolks; mushrooms; and fortified foods such as milk or cereal.

Supplements: If your doctor finds a deficiency, they may suggest a daily supplement. Most adults require 600 IU (15 mcg) daily, while people over 70 need 800 IU (20 mcg).

Be careful with the dosage — too much vitamin D can be toxic and cause such complications as kidney damage.

Where Do We Go From Here?

While COVID-19 is no longer the emergency it once was, the virus still circulates and continues to cause complications — especially among vulnerable populations. Knowing that vitamin D levels may influence how someone fares with an infection opens the door to more targeted prevention efforts.

That might include screening for deficiency in high-risk groups, public health messaging around safe sun exposure, or considering fortified foods in communities with higher rates of deficiency but more research is needed. Clinical trials will be crucial in determining whether vitamin D supplementation could become a recommended part of COVID-19 care protocols. For now, maintaining healthy levels is simply good preventive medicine.

The latest study doesn't claim that vitamin D is a cure for COVID-19. But it adds to a growing body of evidence suggesting that micronutrient deficiencies can shape how our bodies respond to viral infections.

In a post-pandemic world where we're learning to coexist with SARS-CoV-2, this kind of insight is valuable — not just for COVID, but for broader public health. As Beckmann summed it up: “COVID may not be the threat it once was, but understanding who is still at risk, and why, will help us stay a step ahead.”

The U.S. fertility rate dropped to its lowest recorded point in 2024, with fewer than 1.6 children per woman, according to newly released data from the Centers for Disease Control and Prevention (CDC). The statistic marks a continuation of a nearly two-decade-long trend in declining birth rates, one that has shifted the United States closer to the demographic profile of Western European countries.

For context, a fertility rate of 2.1 children per woman is considered the “replacement level,” the point at which a generation can, theoretically, replace itself. The U.S. hovered near that threshold until the late 2000s. But since then, it has slipped steadily, and 2024’s rate of 1.599 puts it well below what’s needed for generational stability without immigration.

Behind the numbers are real-world pressures shaping family planning decisions. Today’s young adults are marrying later, starting families later—or opting out entirely. Financial uncertainty plays a significant role.

“People are concerned about whether they can afford to have children—not just the cost of childbirth, but long-term needs like childcare, housing, and health insurance,” said Karen Guzzo, director of the Carolina Population Center at the University of North Carolina. “Worry is not a good moment to have kids.”

The cost of raising a child in the U.S. has climbed steadily, outpacing wage growth in many parts of the country. And while millennials and Gen Z have higher educational attainment than previous generations, they also carry more debt, face steeper housing markets, and often work in jobs with fewer benefits.

The Long Arc of Decline

To understand the drop in fertility, it's important to zoom out. In the early 1960s, during the postwar baby boom, the U.S. total fertility rate peaked around 3.5. But by the mid-1970s, it had plummeted to 1.7, largely due to the availability of birth control, changing gender roles, and cultural shifts around family size.

There was a brief rebound in the early 2000s, with the rate rising to 2.1 in 2007. But the 2008 financial crisis triggered another sharp downturn—and the recovery in births never quite came.

According to the CDC’s National Center for Health Statistics, the fertility rate in 2023 was 1.621, before dipping further to 1.599 in 2024.

Why Is Trump Administration’s Pushing to Reverse the Trend?

Concerned about declining birth rates, the Trump administration has recently taken steps to try to stimulate family formation. These include:

• An executive order aimed at expanding and reducing the cost of in vitro fertilization (IVF)
• Public endorsements of “baby bonus” incentives, which would provide financial rewards to couples who have children

However, experts remain skeptical of these measures. "These are largely symbolic moves,” said Guzzo. “They don’t address the real obstacles facing families, like paid parental leave, affordable childcare, and housing affordability. Until those are on the table, you’re not going to see a meaningful change.”

While the overall fertility rate declined, total births actually rose in 2024. According to the CDC’s finalized data, there were about 33,000 more births than the previous year, bringing the annual total to just over 3.6 million babies.

This may seem contradictory at first glance. But demographers say it makes sense once you factor in changes in population estimates.

The U.S. Census Bureau updated its estimates for the number of women of childbearing age. The increase in this demographic—largely driven by immigration offset small increases in births in certain age groups, leading to a recalculated (and lower) birth rate.

Initial projections earlier in 2024 suggested that women in their late 20s and 30s were having more children. But the updated report, based on a more complete dataset, found:

• Declines in birth rates for women in their 20s and early 30s
• No significant change for women in their late 30s

So while there may have been slightly more babies born, the pool of women able to give birth also grew—especially due to immigrant populations—pulling the overall fertility rate downward.

Should We Be Alarmed?

Not necessarily. Unlike countries like Japan or Italy, where shrinking populations are already straining healthcare systems and economies, the U.S. population is still growing, thanks largely to immigration. And while birth rates are falling, experts emphasize that this is often a delay, not an outright decision never to have children.

“What we’re seeing is people having kids later, not necessarily choosing not to have them at all,” said Root. “The U.S. still has a natural increase—more births than deaths.”

That said, the economic and policy environments matter. In countries like Sweden and France, which offer strong parental leave policies and subsidized childcare, birth rates have remained more stable despite similar social trends.

As debates about immigration and population policy heat up, the fertility rate is increasingly seen as more than just a demographic metric—it’s a political one.

A sustained drop below replacement level, without compensatory immigration, could eventually lead to workforce shortages, strains on entitlement programs, and broader economic shifts. But solutions, experts argue, will require more than one-time bonuses or headline-grabbing executive orders.

If the U.S. wants to encourage family formation, it will need to invest meaningfully in family support systems: paid leave, healthcare, housing, education, and affordable childcare. Otherwise, the gap between ideal family size and actual fertility will continue to widen.

The drop to a 1.599 fertility rate in 2024 is a milestone but not an emergency. It's a reflection of changing cultural, economic, and personal dynamics in American life. Addressing it will require real policy innovation, not just political talking points.

For now, Americans are still having children, just on their own timeline, and often with more questions than confidence.
