Correlation analysis between some blood properties and atmospheric environmental parameters.

Area of Science:

• Environmental Science
• Hematology
• Biometeorology

Background:

• Erythrocyte sedimentation rate (ESR) is a common blood test.
• Previous research by S.W. Tromp indicated a seasonal weather effect on ESR.
• The influence of meteorological factors on human physiology warrants further investigation.

Purpose of the Study:

• To re-evaluate the influence of weather on erythrocyte sedimentation rates (ESR).
• To investigate new aspects of the weather-ESR relationship beyond seasonal variations.
• To analyze updated data from Leiden, The Netherlands, for the period 1971-1985.

Main Methods:

• Analysis of routine blood donor data from Leiden (1971-1985).
• Correlation of ESR values with meteorological data, including temperature changes and atmospheric fronts.
• Investigation of potential links between ESR fluctuations and solar activity (sunspot numbers).

Main Results:

• A complex influence of weather on ESR was confirmed, extending beyond simple seasonal effects.
• ESR was observed to increase prior to noticeable ground-level warming, possibly due to upper atmospheric changes.
• Periods of low ESR coincided with a higher frequency of occlusion fronts passing over the Netherlands.
• Long-term ESR fluctuations showed limited correlation with sunspot relative numbers.

Conclusions:

• The relationship between weather and ESR is more intricate than previously understood.
• Further research is needed to explore the role of upper atmospheric conditions in modulating ESR.
• The findings support the need for global studies to validate these weather-ESR correlations across diverse geographical locations.
