Everyday habits, subtle health issues, and hidden stressors can quietly drain your energy without you realizing it.

Feeling tired all the time can be frustrating, especially when it starts to feel normal. Many people assume constant fatigue is just part of modern life, but experts say ongoing tiredness is often a sign that something small but important is being overlooked.

Energy levels are shaped by sleep quality, daily routines, nutrition, and mental load, not just how busy you are. Identifying the real reasons behind persistent fatigue can make it easier to regain focus, motivation, and stamina.

Advanced imaging and large-scale analysis revealed that a familiar brain structure plays a far broader role than scientists once assumed.

For decades, neuroscientists believed they had a reliable map of the brain and a clear understanding of what its major regions do. But recent work led by researchers at the Allen Institute for Brain Science suggests that some well-known brain structures may be far more versatile than textbooks imply.

Using high-resolution imaging, massive neural datasets, and machine-learning analysis, scientists identified patterns of activity that had been largely overlooked. Rather than uncovering a brand-new structure, the research revealed a hidden layer of function embedded within the brain’s existing architecture.

Food experts warn that mayo can quietly undo tuna’s health benefits.

Tuna sandwiches have long been marketed as a healthy lunch, but food experts say one common ingredient quietly undermines that reputation. Mayonnaise, often added by habit rather than thought, can turn an otherwise lean, protein-rich meal into something far less heart-friendly.

The concern isn’t just calories. Nutrition specialists point to the type of fat in traditional mayo and how easily it pushes meals into unhealthy territory without people realizing it. Portion sizes also tend to creep up far beyond what labels suggest.

As a result, experts say it may be time to rethink what you mix into tuna. The good news is there are alternatives that keep the sandwich satisfying while aligning better with modern nutrition advice.

Doctors say these changes are common as the body begins the natural process of shutting down.

When someone is nearing the end of life, families often sense that something is changing, even before a doctor confirms it. The final 24 hours can bring physical and behavioral shifts that feel unfamiliar or unsettling, especially for those seeing them for the first time.

While every person’s experience is different, medical professionals and hospice caregivers report a number of common signs that may appear as the body slows down.

Understanding these changes can help families feel less alarmed and more prepared during an emotional and deeply personal time.

Blushing might seem awkward, but it often signals honesty, empathy, and emotional connection to others.

Blushing is often seen as a flustered reaction to embarrassment, but it can play a much deeper role in social dynamics. This involuntary response may serve as a powerful form of nonverbal communication, signaling everything from sincerity to remorse. Far from being a weakness, a blush can build trust, soften tense moments, and reveal emotional depth. Understanding its social value may help foster better communication and stronger interpersonal connections.

Flesh-eating parasites can cause serious skin damage, but global systems help track their spread.

Flesh-eating parasites aren’t science fiction, but their name is more dramatic than medically accurate. These organisms, like those causing leishmaniasis, can destroy healthy tissue by disrupting the body’s own immune response.

They’re typically transmitted through insect bites and favor warm, humid environments. Public health organizations such as the CDC and World Health Organization monitor outbreaks through disease surveillance networks, which help track cases and identify emerging risks before they escalate into larger epidemics.

A closer look at how certain sweeteners avoid raising insulin while still delivering sweetness

Not all low-calorie sweeteners affect the body in the same way, especially when it comes to insulin response. Some alternatives, often used in drinks and packaged foods, show little to no effect on blood sugar or insulin levels. Scientists study how these compounds are absorbed and processed, noting differences in digestion, hormonal triggers, and even gut microbe activity. Understanding these distinctions can help people make more informed choices about sweeteners and metabolic health.
