Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Calculate minutes of sun exposure needed to synthesize adequate vitamin D based on skin type, UV index, latitude, season, and body surface area exposed

Each component has a specific meaning:

  • Skin type — The skin type recorded for the scenario being assessed.
  • UV index — The uv index recorded for the scenario being assessed.
  • Latitude — The latitude recorded for the scenario being assessed.
  • Season — The season recorded for the scenario being assessed.
  • Body surface area exposed — The body surface area exposed recorded for the scenario being assessed.

Note: Interpret the uv vitamin d synthesis result against the thresholds and context described above.

How to Use

Enter the skin type, UV index, latitude, season, body surface area exposed for the scenario you are assessing. Calculate minutes of sun exposure needed to synthesize adequate vitamin D based on skin type, UV index, latitude, season, and body surface area exposed. Use the uv vitamin d synthesis result to inform your calculation.
