What it calculates

The “COWS” calculator computes COWS total score from 11 parameters: resting pulse (bpm), sweating (0–4), restlessness (0/1/3/5), pupil size (0/1/2/5), bone or joint aches (0/1/2/4), runny nose or tearing (0/1/2/4), gi upset (0/1/2/3/5), tremor of outstretched hands (0/1/2/4), yawning (0/1/2/4), anxiety or irritability (0/1/2/4), gooseflesh skin (0/3/5).

Used by professionals and patients to assess health metrics, dosages, and risks.

Example calculation

With parameters Resting pulse = 104 bpm, Sweating (0–4) = 1, Restlessness (0/1/3/5) = 1, Pupil size (0/1/2/5) = 1, Bone or joint aches (0/1/2/4) = 1, Runny nose or tearing (0/1/2/4) = 2, GI upset (0/1/2/3/5) = 2, Tremor of outstretched hands (0/1/2/4) = 1, Yawning (0/1/2/4) = 1, Anxiety or irritability (0/1/2/4) = 1, Gooseflesh skin (0/3/5) = 0 the result is 13.

How to use

  1. Enter resting pulse, sweating (0–4), restlessness (0/1/3/5), pupil size (0/1/2/5), bone or joint aches (0/1/2/4), runny nose or tearing (0/1/2/4), gi upset (0/1/2/3/5), tremor of outstretched hands (0/1/2/4), yawning (0/1/2/4), anxiety or irritability (0/1/2/4) and gooseflesh skin (0/3/5) — each field above is adjustable with a slider.

FAQ

How is BMI calculated?
BMI = weight (kg) / height (m)². Example: 70 kg / (1.75 m)² = 22.9. The WHO normal range is 18.5–24.9; below that is underweight, 25–29.9 is overweight, and 30+ is obese.
Is BMI accurate for everyone?
No. BMI does not distinguish muscle from fat, so athletes may show a high BMI with low body fat. It is also less reliable for teenagers, pregnant people, older adults, and very tall or short individuals.
What are the BMI categories?
Underweight: below 18.5. Normal: 18.5–24.9. Overweight: 25–29.9. Obese class I: 30–34.9; class II: 35–39.9; class III: 40+.
What is a better measure than BMI?
Body fat percentage, waist-to-height ratio (aim for under 0.5), and waist circumference give a clearer picture of health than BMI alone.
