Sanjana Gajbhiye

Sanjana Gajbhiye is a science writer and researcher, and a staff writer at Earth.com, focused on health and science stories that connect human wellbeing with environmental change, ecosystems, and everyday behavior. Her coverage distinguishes itself by staying close to new peer‑reviewed research while explaining how findings about climate, biodiversity, psychology, and child development translate into concrete risks and choices. She writes at scale, with thousands of features that consistently turn dense scientific work into clear narratives about how people live, feel, and stay healthy.

Health at the intersection of environment and behavior

A core strand of her work looks at how environmental change reshapes fundamental health inputs like food quality, air, and exposure to extreme conditions. In a piece on climate change altering food quality and the role of supplements, she follows researchers as they identify nutrient gaps emerging from degraded crops and explores whether dietary supplements can realistically shore up resilience against heat, pollution, and infection. In another feature on heatwaves reversing decades of air pollution progress, she explains how extreme heat allows trees and soils to produce more ozone, undermining regulatory gains and raising fresh concerns for respiratory and cardiovascular health.

She also tracks the health implications of large‑scale efforts to feed the world, as in her article on the complex balance of farming and biodiversity. There she reports on findings that both farmland expansion and intensification damage local ecosystems, then connects these results to recommendations like reducing food waste and meat consumption to ease pressure on land and, by extension, on human and planetary health. Across these stories she treats environment and behavior as inseparable, showing how policy decisions, industry practices, and daily habits jointly determine exposure to risk.

Child development, screen time, and early‑life biology

Sanjana’s health beat includes focused work on critical windows in child development and the long‑term effects of early‑life experiences. She covers research on digital habits through an article examining the key ages when screen time has the biggest impact, emphasizing that timing, not just total hours, shapes developmental outcomes. Her interest in early biology extends to infant nutrition, as in her piece on breast milk doing something for babies that scientists never expected, where she describes newly uncovered functions that reach beyond basic nourishment into immune and developmental pathways.

These topics link back to her broader concern with how modern environments—from digital devices to changing food systems—interact with biology across the lifespan. By anchoring each feature in a specific study and then spelling out practical implications, she makes complex developmental science usable for readers who need to understand long‑term health impacts without wading through technical literature.

Mental health, happiness, and connection with nature

Another recurring thread in her work is the relationship between mental health, psychological traits, and the environments people inhabit. In “Where does happiness come from? It depends on who you are,” she walks through research showing that personality traits, mindsets, and emotional habits shape how individuals experience life, clarifying why the same circumstances can yield very different levels of happiness. In “Natural environments may reduce fear and anxiety,” she reports on experiments where living in a naturalistic setting both blocks the formation of fear responses and can reset existing ones, translating this into plain language about how rich experience broadens judgment and emotional resilience.

Her coverage of “People must reconnect with nature now to save biodiversity” pushes this theme further, connecting nature‑relatedness not just to conservation outcomes but to shifts in societal values and everyday behavior. She explains expert recommendations for integrating nature connection into education, healthcare, and urban planning, highlighting small daily changes—spending more time outdoors, appreciating natural beauty, reducing consumption—as building blocks of wider psychological and ecological change. Together, these stories show how she uses health and psychology as lenses to discuss both individual wellbeing and systemic sustainability.

Biodiversity, ecosystems, and their hidden implications

Although her beat centers on health, Sanjana frequently writes on biodiversity and ecosystem science, framing them as essential context for long‑term human wellbeing. In “Earth may have three times more insect species than we thought,” she explains a new estimate of 14–20 million insect species and clarifies why this enormous hidden diversity matters for ecosystem stability. A companion piece, “Very little is known about 99% of all insects on Earth,” focuses on how researchers combine long‑term field data, spatial comparisons, experiments, and expert judgment to build a more reliable picture of insect health worldwide. She uses these methodological details to show readers how scientific confidence is built, not just what the headline number is.

Her article on migratory predators carrying fear across continents and shaping evolution explores how mobile predators spread “portable fear” that influences prey behavior and evolutionary trajectories, even among species that never share a map. In “Plants use sugar in ways we never imagined,” she covers research revealing that plants use sugar and thermal signals to detect daytime heat, pointing to new understandings of how vegetation responds to climate stress. These features, along with her farming‑and‑biodiversity coverage, underscore a consistent approach: she treats ecosystem science as deeply relevant to future health, showing how changes in insects, predators, and plants cascade back to food systems, disease dynamics, and the stability of the environments people depend on.

Translating complex research through narrative science writing

Across beats, Sanjana’s distinguishing trait is how she turns complex research into narrative‑driven, accessible stories. Her author bio describes her as an experienced science writer and researcher, and her broader professional profile notes that she has written well over two thousand articles translating complex research into accessible global coverage. That scale shows in her ability to move quickly from technical detail to clear explanations, often structuring pieces around a single study, tracing the research questions, summarizing the methods, and then foregrounding the implications for ordinary life.

In “Storytelling can bring science to life and inspire action,” she explicitly advocates for more narrative approaches in science communication, encouraging formats that let readers see the journey of research rather than just its results. Her own work mirrors that advice: she uses straightforward language, draws out vivid examples—such as fear fading after a week in nature or farmland intensification pushing ecosystems past recovery—and connects them to broader themes like resilience, sustainability, and behavioral change. Her path into science communication through freelance content work reinforces this focus on usability, giving her a style that is informative, direct, and grounded in evidence while remaining approachable for non‑specialist audiences.
