That cites a primary study that spawned a bunch of work, recently
reviewed by researchers in Italy. Their bottom line is that "These
results support the presence of an association between DST and a modest
increase of AMI ["heart attack"] occurrence, especially for the spring
shift, and with no definite gender specific differences." and "The
risks of AMI increases modestly but significantly after DST transitions".
To my mind the more-concerning health effects of daylight-saving time
occur not during the twice-yearly transitions, but during the time that
DST is in effect - which is the whole year when a location uses
"permanent DST". Unfortunately these effects have not been studied as
much, although experts are warning us that these effects are worrisomely
negative (see, e.g., ).
