Silage, soil, manure - making the most out of.

@dimgrr @USMortality Treatments matter but if conditions are good, people don't fall ill and recover faster regardless of treatment in hospitals. Epidemiologically small things matter. For example duration of bad conditions, timing of a school break in relation to the worst weather conditions, etc.

[Kaur Parve @kparve]

@dimgrr @USMortality It was and it still is mostly about weather, favouring or not favouring catching cold and falling ill. North of Italy had terrible conditions for about a month and people fell ill in herds. Southern part had beautiful spring. Netherlands had such conditions for a short while.

The most pseudo-scientific term in existence: 'rare'.

@ClareCraigPath For Northern Europe, the winter 2019/20 was exceptionally soft. This was most probably a major reason why substantial number of elderly survived. Dec21-Feb22 had massively fluctuating atmospheric pressure naturally passing away lots of people with heart conditions.

@gerdosi ... under some stress conditions like shortage of water.

@gerdosi Would make somewhat good sense if virus particles are produced by the same bacteria...

@ClareCraigPath @Johnincarlisle Bringing to attention - environmental conditions leading to susceptibility... A massive bit for understanding respiratory diseases and almost entirely overlooked. Thanks for so wonderful and refreshing discussion.

@PatrickSSte @0bj3ctivity @ukhadds @SuebeeTexan @SolidEvidence @RadCentrism @notkent @MarvinH2_G2 @kallmemeg Imagine blood vessels constricting in case of dehydration.

[Kaur Parve @kparve]

@PatrickSSte @0bj3ctivity @ukhadds @SuebeeTexan @SolidEvidence @RadCentrism @notkent @MarvinH2_G2 @kallmemeg A hidden but massive impact comes from the hydration status. Dehydrated body cannot supply sufficient water for the upper airways. If you have first itchy feel of coming illness deep inside your nose take a pint of water and it is gone in minutes.

@PatrickSSte @ukhadds @0bj3ctivity @SuebeeTexan @SolidEvidence @RadCentrism @notkent @MarvinH2_G2 @kallmemeg Houses heated by ovens are able to buffer the humidity drop in the arrival of cool season. Stores, schools and new residential buildings may have 20% RH inside the next day when AH drops to respective level but RH in older houses stays higher for weeks.

@PatrickSSte @ukhadds @0bj3ctivity @SuebeeTexan @SolidEvidence @RadCentrism @notkent @MarvinH2_G2 @kallmemeg Which more important - indoors or out?

Based on the time spent - indoors in most of the cases. In contemporary well ventilated and centrally heated houses humidity indoors is translated from humidity outdoors by a formula: AH(in)=AH(out). 1/

@PatrickSSte @ukhadds @0bj3ctivity @SuebeeTexan @SolidEvidence @RadCentrism @notkent @MarvinH2_G2 @kallmemeg Inhaled air must be 36C/100% RH or have about 40 g water per each kg of air in lungs every breath and the main thing that counts for the epithelium is how much water does the needed amount of air contain before. 25C/25%RH requires less water than 0C/100%RH for lungs. 2/

@PatrickSSte @ukhadds @0bj3ctivity @SuebeeTexan @SolidEvidence @RadCentrism @notkent @MarvinH2_G2 @kallmemeg If you think about air drying biological systems more or less, then yes, RH is the main parameter to look at together with temperature. However, moisturizing inhaled air is totally different matter. It is not about the power of air to dry. 1/

@PatrickSSte @ukhadds @0bj3ctivity @SuebeeTexan @SolidEvidence @RadCentrism @notkent @MarvinH2_G2 @kallmemeg Can you please explain.

[Kaur Parve @kparve]

@PatrickSSte @ukhadds @0bj3ctivity @SuebeeTexan @SolidEvidence @RadCentrism @notkent @MarvinH2_G2 @kallmemeg With a major AH drop, everyone in the region is affected and details determine who will suffer: long stay in very dry environment (like in a well ventilated hospital or school), activities favouring dehydration, and poor rehydration routines are definitely increasing the risk.

[Kaur Parve @kparve]

@PatrickSSte @ukhadds @0bj3ctivity @SuebeeTexan @SolidEvidence @RadCentrism @notkent @MarvinH2_G2 @kallmemeg When AH drops then upper respiratory epithelium needs to supply sometimes 10-20% more water overnight. It then depends on the homeostatic capacity of an individual if the epithelium is able to adjust. Older people have more problems with homeostasis typically.

[Kaur Parve @kparve]

@PatrickSSte @ukhadds @0bj3ctivity @SuebeeTexan @SolidEvidence @RadCentrism @notkent @MarvinH2_G2 @kallmemeg Huge majority of papers on diseases and humidity look at relative humidity which is pretty pointless as are the conclusions. All of the few papers looking at absolute humidity report significant correlation.

[Kaur Parve @kparve]

@ukhadds @PatrickSSte @0bj3ctivity @SuebeeTexan @SolidEvidence @RadCentrism @notkent @MarvinH2_G2 @kallmemeg The impact of change of both temperature and absolute humidity on physiology is massive. People adjust the temperature to the comfort zone because they feel the deviation immediately. They are more tolerant towards changing AH and react usually when damage is already done.

[Kaur Parve @kparve]

@PatrickSSte @ukhadds @0bj3ctivity @SuebeeTexan @SolidEvidence @RadCentrism @notkent @MarvinH2_G2 @kallmemeg AH and temperature are related to some extent. Thus it is possible to notice some correlation between T and hospitalization. But by far not as clear as with AH and hospitalization.
