The Effect of Weather on Health

19-year-old Helena Muffly wrote exactly 100 years ago today: 

Monday, April 20, 1914:  There wasn’t much coming this way except the rain.

Her middle-aged granddaughter’s comments 100 years later:

This was the second rainy day in a row. According to a book published in 1914, The Principles of Hygiene by D.H. Bergey, MD, there was a relationship between weather and health.

The Influence of Precipitation on Health

The immediate effect of a fall of rain is to cleanse and purify the air from dust of all sorts, organic and inorganic, and from micro-organisms. So far the influence of rain is decidedly beneficial to health; but when rainfall is so excessive as largely to increase the humidity of the air, its hygienic effect becomes merged in that of humidity.

The Influence of Humidity on Health

If the relative humidity be increased, there will be a hindrance to the escape of water from the body; and when this condition is combined with a high temperature the heat is far more oppressive than when the atmosphere is dry and allows free evaporation. On the other hand, a moist, cold atmosphere is far more distressing than when the air is dry, and there is but little movement.

The Effects of Wind Upon Health

It is complex and not well defined how wind affects health. All wind favors evaporation, and therefore loss of heat from the body. Winds that are and moist are mild and relaxing; dry, cool winds are bracing; but cold winds are penetrating, and considered dangerous to persons of delicate constitutions.

Sunlight as a Disinfectant

Sunlight is an efficient disinfectant. This agent is constantly acting and, no doubt, removes most of the detrimental agents on surfaces exposed to the sun. Most bacteria grow best in the dark.

  1. Nice post, great information. Sometimes I love the rain, as it allows me to relax…clean and do things around the house, and most happily grab a book and get lost in words :-)

  2. He has the sunshine bit right. I don’t know about the other matters, but having a cold, damp house is very bad for one’s health; that’s a fact!

  3. “Persons of delicate constitution”: I think I’ve known a few of those through the years!

  4. Yes, a relationship in many ways between weather and health…both physical and mental!!!

    • I agree. . .sometimes I think that the relationship between weather and mental health is almost more important than the link between weather and physical health.

  5. What about snow in April??? :)

  6. […] Yesterday, I shared information from a book published in 1914 about the relationship between weather and health. Since Grandma didn’t write much a hundred years ago today, I’ll share some more from the book about the relationship seasonal variations and health. […]
