📊 Stanford Research: Body Temperatures Are Dropping
📊 Stanford Medicine Research Update
A 2020 Stanford Medicine study analyzed 677,000 temperature measurements over 157 years and found average body temperatures have decreased by 0.03°C per decade. The traditional 37°C (98.6°F) standard from 1868 is outdated. Modern normal range: 36.4°C to 36.6°C (97.5°F to 97.9°F).
36.4°C to Fahrenheit Conversion: The New Normal Standard
(36.4°C × 9/5) + 32 = 97.5°F
- Multiply 36.4 by 9/5: 36.4 × 1.8 = 65.52
- Add 32 to the result: 65.52 + 32 = 97.52
- Final result: 36.4°C = 97.5°F (new normal lower limit)
36.4°C Readings: Updated Normal Standards by Method
36.4°C (97.5°F) represents the new lower limit of normal. Understanding measurement differences is crucial as medical standards update from the old 37°C (98.6°F) benchmark.

36.4°C: Modern Temperature Standards by Age
👶 Newborns - Modern Healthy Baseline
36.4°C = 97.52°F
- 36.4°C (97.5°F) aligns with new lower average standards
- Newborns often run cooler than old 37°C benchmark
- Monitor patterns - single readings matter less
- Contact pediatrician only if consistently below 35.8°C
👶 Infants - Within Updated Normal Range
36.4°C = 97.52°F
- 36.4°C reflects modern average temperature research
- Normal infant range updated: 36.0-37.5°C
- Lower temps increasingly common since 2000
- Doctor visit if below 35.5°C or above 38°C
🧒 Children - New Normal Standard
36.4°C = 97.52°F
- 36.4°C represents modern average baseline
- Kids show same temperature decline as adults
- Healthy range expanded to 36.0-37.2°C
- Watch for consistent readings below 35.8°C
👨🦳 Adults - Why You're Cooler Than 98.6°F
36.4°C = 97.52°F
- 36.4°C (97.5°F) is the new average lower limit
- Stanford study: 0.03°C drop per decade since 1860s
- Better health, lower metabolism, indoor living explain drop
- Your 'low' temp is actually modern normal
Updated Body Temperature Scale: Old vs New Standards
Compare outdated 1860s standards with 2020s research:
| Celsius (°C) | Fahrenheit (°F) | 2025 Medical Assessment |
|---|---|---|
| 35.5°C | 95.9°F | Low normal - Monitor if persistent |
| 36.0°C | 96.8°F | Normal - Lower average range |
| 36.4°C | 97.5°F | ✅ Modern average lower limit (Stanford 2020) |
| 36.6°C | 97.9°F | ✅ Modern average upper limit |
| 37.0°C | 98.6°F | Old standard (1868) - Now considered warm |
| 37.5°C | 99.5°F | High normal / Low-grade fever |
| 38.0°C | 100.4°F | Fever threshold - Unchanged |
Frequently Asked Questions
36.4°C is NOT too low. Stanford Medicine's 2020 research shows average body temperatures have dropped 0.03°C per decade since the 1860s. The 37°C (98.6°F) 'standard' is outdated. Modern normal range is 36.4°C to 36.6°C (97.5°F to 97.9°F). Your temperature is perfectly healthy.
Stanford researchers identified three factors: 1) Better health and lower inflammation due to medical advances; 2) Reduced metabolic rate from modern sedentary lifestyles; 3) Climate-controlled environments reducing body workload. 36.4°C reflects these improvements, not a problem.
The 2020 Stanford study analyzed 677,423 temperature measurements from 1892-2017. Key findings: Men's temps dropped 0.59°C, women's 0.32°C. Average temps decreased 0.03°C per birth decade. The 37°C (98.6°F) standard from 1868 is no longer accurate for modern populations. 36.4°C-36.6°C is the new normal.
Yes. Children show the same temperature decline as adults in Stanford's research. 36.4°C (97.5°F) is a healthy temperature for all ages. Pediatricians now recognize broader normal ranges. Contact doctors only for consistent readings below 35.5°C or accompanying illness symptoms.
Trust modern research. The 37°C (98.6°F) standard comes from a single 1868 German study of 25,000 people. Modern Stanford research (2020) uses 677,000+ measurements. Medical institutions including Cleveland Clinic and Johns Hopkins now accept 36.4°C-36.6°C as the updated normal range. 36.4°C is medically sound.
To convert 36.4°C to Fahrenheit: Multiply 36.4 by 9/5 (or 1.8) = 65.52; Add 32 to the result: 65.52 + 32 = 97.52; Rounded: 36.4°C = 97.5°F. This temperature represents the modern average lower limit according to 2020 Stanford Medical research.
