ngd- Daylight Savings Time is a spawn of Satan…

Summary: Chronobiologists warn changing to daylight savings can have serious effects on both brain and general health. The change in time during spring was linked to a 24% increase in severe cardiovascular events in women. Researchers also noted the sudden change in time alters circadian rhythms, reduces the production of natural melatonin, impacts cognitive function, and may also foster tumor growth.

“We must bear in mind that our state of health is based on the maintenance of rhythmic changes of all the functions of our organism, from the sleep/wake cycle to the rhythm of brain neurotransmitters (and therefore, of our cognitive functions); hormonal rhythms; metabolic rhythms; rhythms of cell division; and rhythms in the mechanisms of cellular repair, both at the cerebral level and at the level of peripheral organs.”

An abrupt change

Changing the clocks implies a sudden alteration of these rhythms, because in 24 hours we modify the subjective time of sunrise and sunset. “The circadian system is controlled by the photoperiod or light/dark rhythm. In turn, this regulates the nocturnal production of melatonin, which is the genuine endogenous synchronizer of these rhythms,” observes Acuña.

“This sudden change therefore also triggers a change of time in the nocturnal production of melatonin, leading to a process known as internal desynchrony, which prevents the biological clock from maintaining ‘order’ in the body.” It then takes about 3 to 5 days to work properly again.
