Rachel Sacks

Rachel Sacks is a wellness reporter for The New York Post and a freelance health writer who turns new medical research and expert insight into clear, practical guidance on everyday health and wellness. Her coverage centers on how subtle symptoms, lifestyle habits and emerging treatments signal deeper issues in the body, with a strong focus on preventive health, men’s health and the way people actually feel in daily life.

Preventive health and warning signs

Sacks consistently frames health news around early warning signs and what they mean for long-term wellbeing. In her reporting on “embarrassing” symptoms men hide from doctors, she highlights swollen testicles, erectile dysfunction, frequent urination and depression-like fatigue as red flags for conditions such as testicular cancer, vascular disease, diabetes and low testosterone. Her piece on erection problems as a “canary in a coal mine” continues this theme, explaining how sexual health changes can precede cardiovascular issues by several years and arguing for proactive screening and conversation with clinicians.

She extends this preventive lens beyond men’s health. Her work on a supportive care drug gaining attention among parents of autistic children tracks how leucovorin prescriptions surged more than 2,000% in three years and became difficult to access, balancing hopeful trial results against the realities of demand and regulatory limits. Sacks also writes about simple habits that reduce long-term risk, such as a 20-minute daily walk that can cut the likelihood of early death, cardiovascular disease, diabetes and dementia, grounding her service advice in studies on step counts, blood pressure and mortality. Across this coverage, she distinguishes herself by connecting everyday symptoms and routines to serious conditions in plain language, while keeping the emphasis on what readers can do early rather than on crisis care.

Translating studies into everyday habits and feelings

A recurring feature of Sacks’ work is her translation of complex research into relatable explanations of how the body feels and behaves. In a piece on why being in shape can make people less angry, she walks through findings that fitter participants experienced lower anger and anxiety after stress exposure, then explains the role of discipline, emotional resilience and brain chemicals such as serotonin, endorphins and dopamine. Her reporting makes clear how regular exercise changes mood and stress responses, not just fitness metrics.

Similarly, when she writes about why women often feel colder than men, she breaks down the science of resting metabolic rate, body size, lean muscle mass and body fat as thermal insulation. She incorporates expert quotes to show that warmth or coldness depends on body type and composition, and notes external factors such as stress, smoking, diet and hormonal birth control that can shift temperature perception. In her walking piece, she again relies on expert trainers and cardiometabolic studies to explain how even around 3,800 steps per day can reduce dementia risk and how post-meal walks help muscles use glucose more efficiently. Across these explainers, Sacks’ distinguishing trait is her focus on what research means for everyday sensations — feeling angry, chilled, tired or clear-headed — and the small behavior changes that can alter those sensations.

Hormones, taboo topics and life stages

Sacks frequently addresses topics that many people find uncomfortable to discuss, using a straightforward tone that normalizes sensitive health issues. Her men’s health reporting tackles erectile dysfunction, swollen testicles and reduced libido as clinical signals rather than purely intimate concerns, linking them to vascular health and hormonal balance. She also covers hormonal and reproductive themes across genders and life stages, including pieces on how ADHD affects menstrual cycles, pregnancy and menopause, and how laxatives could influence memory and attention through gut–brain pathways. This work fits with her broader interest in the intersections between hormones, mood, cognition and physical symptoms, from low testosterone and depression-like fatigue in midlife men to temperature differences tied to metabolic rate and body composition.

Her autism treatment coverage likewise engages with family anxieties, clinical trial data and off-label use, walking readers through how a drug approved for cerebral folate deficiency came to be adopted by parents seeking improvements in speech and communication for their children. By returning to subjects that are often considered private or complex — sexual health, menstruation, neurodevelopment, mood and aging — and treating them as practical health questions anchored in evidence, Sacks offers a blend of service journalism and research-driven reporting that goes beyond surface-level wellness trends.

Freelance health writing and service journalism

Alongside her role at the Post, Sacks works as a health, wellness and lifestyle writer and copywriter for a range of brands and digital publications. She describes her career as more than a decade of blending research, storytelling and strategy as both a service journalist and a copywriter, creating editorial and marketing content across health, wellness and related lifestyle topics. Her portfolio includes contributions on health and wellness for direct-to-consumer health companies as well as coverage for other news and service outlets, where she continues to focus on accessible, research-backed guidance.

This dual track in newsroom reporting and brand-oriented writing shapes her style: she favors concise, benefit-focused headlines, relies heavily on expert interviews and recent studies, and structures articles as clear explainers or numbered guides that readers can act on quickly. Whether she is covering the latest JAMA Network Open study, a new angle on cardiovascular risk, or everyday questions such as why people feel cold, Sacks’ body of work reflects a consistent commitment to turning health news into usable advice.
