General health
Fevers, coughs, pains and the everyday questions everyone eventually asks.
When is a fever dangerous in an adult?
Fever itself is a tool, not the enemy; most adult fevers ride out safely at home with fluids and rest. The number matters less than the company it keeps.
What helps a sore throat fast?
The proven quick relievers: regular paracetamol or ibuprofen taken by the clock rather than waiting for pain, warm salt water gargles, honey in warm drinks, medicated lozenges, and humid air. Most viral sore throats improve markedly within three to five days.
Why won't my cough go away after a cold?
A cough outliving its cold by weeks is usually post-viral airway irritation: inflamed passages overreact to cold air, talking and laughing long after the virus has gone. Average cough duration is nearly three weeks, far longer than most people expect.
How do I know if my headaches are migraines?
Migraine is more than a bad headache: typically one-sided, throbbing, moderate to severe, worsened by movement, with nausea or sensitivity to light and sound, lasting hours to days. Some get warning auras of shimmering vision. Tension headaches, by contrast, band the whole head without the trimmings.
What causes lower back pain and when is it serious?
The overwhelming majority is mechanical: muscles, ligaments and discs objecting to load, posture marathons or sudden effort, and it improves within weeks with movement, not bed rest. Staying active is the treatment; bed rest prolongs it.
Why do my joints hurt and feel stiff in the morning?
The clock tells the story: stiffness easing within thirty minutes of moving points to wear-and-tear osteoarthritis, worse after use, better with rest. Stiffness lasting beyond an hour, especially in both hands' small joints with swelling, points to inflammatory arthritis, which is a different disease with a different urgency.
What should I do for a sprained ankle?
First 48 hours: relative rest, ice wrapped in cloth for short spells, gentle compression and elevation, with pain relief as needed. Then the part most people skip: early gentle movement and balance work, which speeds recovery and prevents the loose, re-spraining ankle.
How would I know if I have asthma as an adult?
Adult asthma announces itself in patterns: cough, wheeze, chest tightness or breathlessness that comes in episodes, worse at night and early morning, triggered by colds, exercise, allergens, cold air or smoke. A dry night cough can be its only voice.
What causes frequent nosebleeds?
Dry air, nose picking, forceful blowing, allergy sprays used wrong and blood-thinning medicines cause nearly all of them; the fragile vessels sit just inside the front of the nose.
Why am I losing weight without trying?
Unintentional loss of more than about 5 percent of body weight in six to twelve months is a symptom that always deserves investigation, never celebration by default.
What is a normal body temperature, and what counts as fever?
Normal is a range, not 37.0: most adults run 36.1 to 37.2 C (97 to 99 F), lower in the morning, higher by evening, and slightly lower in older age. Modern averages run cooler than the 19th century textbook number.
Do I need a tetanus shot for this cut?
The rule of thumb: clean minor wounds need a booster if your last was over ten years ago; dirty, deep or puncture wounds, anything with soil, rust, animal contact or crush damage, shorten that to five years.
Why do my hands tingle or go numb?
Position solves most of it: nerves squeezed at the wrist or elbow wake you with numb hands or make phones and steering wheels tingle. Night tingling of thumb through ring finger, shaken off the wrist, is classic carpal tunnel.
How much water should I actually drink a day?
The eight-glasses rule is folklore; needs vary with size, climate, activity and diet, and food supplies about a fifth of fluid. The built-in gauge works: drink when thirsty, and aim for pale-yellow urine, the single most honest hydration indicator.
What are the signs of dehydration in adults?
Early: thirst, dark scant urine, dry mouth, headache and fatigue, the routine end of a hot day. Advancing: dizziness on standing, racing heart, confusion, and skin that tents when pinched; in older adults, new confusion is often the loudest sign.
Why does my ear feel blocked?
The usual suspects: wax buildup, pressure from colds and flights as the ear's ventilation tube swells shut, fluid lingering after infections, and water trapped from swimming. Each feels remarkably similar from inside.
Is cracking my knuckles harmful?
The famous pop is gas bubbles collapsing in joint fluid, not bones grinding. Decades of studies, including one researcher who cracked one hand for sixty years, find no arthritis link. The habit is acoustically annoying and medically innocent.
What should be in a home first-aid kit?
The core: adhesive bandages in sizes, sterile gauze and tape, an elastic wrap, antiseptic solution, tweezers, scissors, disposable gloves, a digital thermometer, paracetamol and ibuprofen, an antihistamine, oral rehydration salts, and burn gel or cling film for burns.
Why do I get leg cramps at night and what helps?
Night calf cramps hit a third of adults, more with age, pregnancy, dehydration, hard exercise, standing days, and some medicines, diuretics and statins among them. Most have no sinister cause.
What is the fastest way to get over a cold?
Nothing shortens a cold much, so the win is feeling better while it runs: sleep genuinely aids immune clearance, fluids loosen secretions, paracetamol or ibuprofen tame the misery, saline rinses and decongestants open noses, honey calms coughs better than most syrups.
My lymph nodes feel swollen. When should I worry?
Nodes are immune stations, and they swell honestly with infections: tender, mobile, pea-to-grape lumps in the neck during a sore throat are the system working, settling over two to three weeks.
What causes mouth ulcers and how do I heal them faster?
Common aphthous ulcers run in families and flare with stress, minor bites, certain toothpastes with SLS foaming agents, acidic foods, and dips in iron or B12. They are not contagious, unlike cold sores.
When is a child's fever an emergency?
Age sets the rules: any fever in a baby under three months is an urgent same-day assessment, no exceptions. Beyond that age, the child's behavior outranks the thermometer: a 39.5 child playing and drinking is usually safer than a 38.2 child who is limp and listless.
Why do I wake up drenched in sweat at night?
Sort the room from the body first: heavy duvets, warm rooms and evening alcohol produce most damp nights. True night sweats soak nightwear and sheets despite a cool room.
How can I actually boost my immune system?
The unglamorous truth: the immune system is boosted by sleep, not products. Seven-plus hours, regular exercise, a varied fiber-rich diet, healthy weight, managed stress, no smoking, moderate alcohol and staying vaccinated outperform every capsule sold with the word immunity on it.
