So maybe I shouldn't go winter camping in -40F weather anymore. No worries about running in hot weather, I can't run yet.

When temperatures are extremely high or low, there is a significant
increase in the number of deaths caused by heart failure or stroke. This
has been confirmed by epidemiological studies conducted by researchers
at the Helmholtz Zentrum München, who have now published their results
in the medical journal Heart.
Epidemiological studies have repeatedly shown that death rates rise
in association with extremely hot weather. The heat wave in Western
Europe in the summer of 2003, for example, resulted in about 22,000
extra deaths. A team of researchers led by Dr. Alex-andra Schneider at
the Institute of Epidemiology II at the Helmholtz Zentrum München
examined the impact of extreme temperatures on the number of deaths
caused by cardiovascular disease in three Bavarian cities and included
both high and low temperatures in the study.
“Our findings confirm the results of our previous studies, which
indicated that the elderly and people with pre-existing medical
conditions respond particularly sensitively to heat and cold,” says
Alexandra Schneider. “If you are aware of the effects of air
temperature on health, you can identify population subgroups who are
particularly at risk and take preventive action.”
The elderly are particularly at risk
Dr. Susanne Breitner, Dr.
Alexandra Schneider and Prof. Annette Peters evaluated almost 188,000
deaths due to cardiovascular disease between 1990 and 2006 in the cities
of Munich, Nuremberg, and Augsburg. They were able to demonstrate that
when temperatures rose from 20°C to 25°C or fell from -1°C to -8°C, the
number of deaths from cardiovascular disease increased significantly by
9.5% and 7.9%, respectively. While the effects of the heat lasted for
one or two days, the effects of cold weather lasted for up to two weeks.
Elderly people were most affected. The impact on death rates due to
heart failure, arrhythmia and stroke was particularly striking.
The mechanisms that cause these deaths, however, are not yet fully
understood. Up to now it has been known that high temperatures, amongst
other things, can affect the blood-clotting mechanism (haemostasis) and
make the blood more viscous, thereby increasing the risk of thrombosis.
Furthermore, as decreasing temperatures have an impact on blood
pressure, it can be assumed that there is a link between cold
temperatures and the increase in cardiovascular events and stroke.
Preventative programs
“Our findings give an indication of the
diseases that are responsible for the observed link between air
temperature and death rates, and thus provide a partial explanation as
to why some people react more strongly to heat or cold than others and
are, therefore, exposed to a greater health risk on hot or cold days,”
says Alexandra Schneider. “These results are important in order to
develop or adapt preventive programs and codes of practice.”
The scientists plan to conduct further research into the mechanisms
that may be responsible for the health effects observed during cold and,
in particular, hot temperatures. They are also interested in possible
interactions with air pollutants, which are required in order to predict
the effects of climate change on the health of the population,
especially in cities and in major conurbations.

Use the labels in the right column to find what you want. Or you can go thru them one by one, there are only 28,972 posts. Searching is done in the search box in upper left corner. I blog on anything to do with stroke.DO NOT DO ANYTHING SUGGESTED HERE AS I AM NOT MEDICALLY TRAINED, YOUR DOCTOR IS, LISTEN TO THEM. BUT I BET THEY DON'T KNOW HOW TO GET YOU 100% RECOVERED. I DON'T EITHER, BUT HAVE PLENTY OF QUESTIONS FOR YOUR DOCTOR TO ANSWER.
Changing stroke rehab and research worldwide now.Time is Brain! trillions and trillions of neurons that DIE each day because there are NO effective hyperacute therapies besides tPA(only 12% effective). I have 523 posts on hyperacute therapy, enough for researchers to spend decades proving them out. These are my personal ideas and blog on stroke rehabilitation and stroke research. Do not attempt any of these without checking with your medical provider. Unless you join me in agitating, when you need these therapies they won't be there.
What this blog is for:
My blog is not to help survivors recover, it is to have the 10 million yearly stroke survivors light fires underneath their doctors, stroke hospitals and stroke researchers to get stroke solved. 100% recovery. The stroke medical world is completely failing at that goal, they don't even have it as a goal. Shortly after getting out of the hospital and getting NO information on the process or protocols of stroke rehabilitation and recovery I started searching on the internet and found that no other survivor received useful information. This is an attempt to cover all stroke rehabilitation information that should be readily available to survivors so they can talk with informed knowledge to their medical staff. It lays out what needs to be done to get stroke survivors closer to 100% recovery. It's quite disgusting that this information is not available from every stroke association and doctors group.
