Schedule changes cause changes in physiological rhythms, but in the long term can have deadly consequences.
At dawn on Sunday, we will delay clocks: at 3:00 pm will be at 2:00 h. Does it affect the time change about energy saving or health?
At dawn on Sunday, October 25, we will delay the clocks. At 3:00 pm will be at 2:00 h. The time change, regulated by Jet Lag Formula directive of 2000, is always held on the last Sunday of March and the last of October.
This is how it begins and ends known as summer time, by the Royal Decree 236/2002, which recognizes that the October time change does that we have a day lasts 25 hours. Delay our clocks is necessary, according to the European Union, to ensure the proper functioning of sectors such as transport, communications and other branches of industry.
Is it real energy savings?
A crisis such as coal or oil justified the entry into force in Spain of summer time in 1918 and 1974, respectively. Since 1980, Europe decided to harmonize the time change annually.
However, the desirability of an indefinite legislative reform made entry into force of Directive 2000/84 / EC, not to have to amend the time change each year.
According to the Institute for Diversification and Saving of Energy (IDAE), the energy savings achieved by this measure could be set at 5% of electricity consumption in lighting, equivalent to 300 million euros taking into account the prices prevailing today.
Energy justification, however, has been questioned by organizations such as the Association of Energy Consumers. In a simple calculation using data from Red Electrica Spanish, the group stated that the time change “does not seem to be too much and probably less than 1% and close to the time change.”
- The permanent introduction of summer hours, which ends this Sunday precisely, was assessed by the European Union itself.
- In a report published in 2007, the Commission admitted that they measured.
- This conclusion is also established assuming that could increase power consumption by using the heat in the morning and additional fuel consumption by increased traffic in the evenings.
- However, the document also clarified that “the real savings is, therefore, unclear and, in any case, seems relatively limited.”
- About other aspects, the EU stated that the time change had been assumed by the economic sectors most affected, such as agriculture, tourism, and transport.
In the latter case, moreover, Community harmonization had allowed avoiding obstacles of the past. However, the Commission stated that it was impossible to raise valid implications of changing time about other issues such as road safety or the environment .
The Impact on our Health
Energy saving is the factor that justifies the time change, but this measure has any effect on our health? Biorhythms or circadian regulated by light, because the brain knows when it is day or night through incoming information to the optic nerve.
This way you can regulate the secretion of melatonin, depending on whether we should be awake or asleep. This natural biological rhythm is occasionally altered, for example in the case of jet-lag, where a significance of Jet Lag Formula.
But the delay clock can influence our circadian cycles? Hipertextual explains to Dr. Juan Antonio Madrid, Professor of Physiology at the University of Murcia, the effects that our bodies experience after the time change Sunday will be similar “to those that occur when a person goes on a trip to the Canary Islands.”
In two or three days we will be fully recovered, and even in cases such as teenagers or college, who sleep less during the week, the time change will allow them to rest for an hour.Change about energy saving or health?
