We track our phone’s battery percentage, Wi-Fi strength, and screen time — but how often do we track our body’s stats?
Health awareness doesn’t always mean medical expertise. It begins with knowing your body’s baseline metrics — the key numbers that silently reflect your wellbeing.
Let me share simple yet powerful health basics everyone should know — whether you’re a student, working professional, or retired grandparent.
What are the most important health numbers everyone should know?
Here are 18 vital signs and health indicators every person should know — from blood pressure (120/80) and pulse (70–100) to vitamin D3 (20–50 ng/ml) and B12 (200–900 pg/ml).
1 Blood Pressure: 120/80 mmHg
The universal gold standard.
A healthy BP ensures your heart is efficiently circulating blood without overstraining.
📌 Tip: Too high or low? Manage salt intake, hydration, and stress.
2 Pulse Rate: 70–100 bpm
Your pulse reflects heart rhythm and oxygen flow.
Lower rates indicate strong fitness; higher rates can signal anxiety or fatigue.
3 Body Temperature: 36.8–37°C
Normal temperature range — slight variations are fine.
Fever = body fighting infection; low temperature = fatigue or hypoglycemia.
4 Breathing Rate: 12–16 per minute
Steady breathing means your lungs and oxygen levels are healthy.
Practice slow, mindful breathing to calm the nervous system.
5 Hemoglobin (Hb)
Male: 13–18 g/dl
Female: 11.5–16 g/dl
Hemoglobin carries oxygen.
Low Hb = anemia, fatigue, or low iron intake.
6 Cholesterol: 130–200 mg/dl
Balanced cholesterol supports heart health.
High levels can block arteries, while very low can affect hormone balance.
7 Potassium: 3.5–5 mEq/L
Essential for muscle function and nerve health.
Both deficiency and excess can cause heart rhythm changes.
8 Sodium: 135–145 mEq/L
Regulates fluids, muscles, and nerves.
Watch your salt — both excess and deficiency matter.
9 Triglycerides: ≤ 220 mg/dl
The “energy reserve” fat.
High triglycerides = risk of heart disease and metabolic syndrome.
10 Total Blood Volume: 5–6 Liters
The lifeline — your body’s fuel transport system.
Drink enough water and keep your iron and hemoglobin in check.
11 Blood Sugar
Children: 70–130 mg/dl
Adults: 70–115 mg/dl
Keep your glucose steady — avoid sugar spikes, eat balanced meals, and move daily.
12 Iron: 8–15 mg/day
Vital for oxygen transport and energy.
Low iron = tiredness, pale skin, and poor focus.
13 White Blood Cells (WBC): 4000–11000/µL
Your immune army.
Low = weak defense; high = infection alert.
14 Platelets: 150,000–400,000/µL
They stop bleeding.
If too low, you may bruise easily; if too high, it can risk clotting.
15 Red Blood Cells (RBC): 4.6–6 million/µL
The oxygen carriers — more in men, fewer in women.
Consistent exercise and leafy greens help maintain them.
16Calcium: 8.6–10.3 mg/dl
For strong bones, heart rhythm, and nerve function.
Milk, yogurt, and sunlight are your best friends.
17 Vitamin D3: 20–50 ng/ml
The sunshine vitamin — crucial for bones, mood, and immunity.
Most adults today are deficient. Go outdoors daily!
18 Vitamin B12: 200–900 pg/ml
Essential for brain, nerves, and energy.
Vegetarians often fall short — include dairy, eggs, or supplements.
🌟 Why These Numbers Matter
These aren’t just “medical stats.”
They’re your body’s daily dashboard.
When you understand these figures, you can prevent problems before they start.
✨ Awareness is not anxiety — it’s empowerment.
When to Check These Levels
Blood pressure and pulse: Weekly
Blood sugar and Hb: Every 3–6 months
Vitamin D, B12, Calcium, Lipids: Every 6–12 months
🧭 Final Thought
Health isn’t about perfection — it’s about attention.
When you know your numbers, you know your health story.
