The nightmares could make you age faster

There are calm nights. Meanwhile, where we sleep peacefully and during which the dreams are soft and pleasant. For example, There are others. Similarly, where we wake up in sweat, because of a nightmare that has grown us violently from our sleep. Moreover, Can we die earlier because of these bad dreams? However. Moreover, The question seems a little excessive, but a study of the Imperial College of London has just confirmed this link.

Frequent nightmare is a psychic, but also physical inconvenience. Furthermore, Abidemi Otaiku. Therefore, one of the authors of the study, affirms it: ” People who regularly make nightmares age faster and die earlier ». Meanwhile, What is the cause of this correlation? Therefore, Measurable alterations cell aging.

The brain in night distress ages faster – Nightmares could make you age new

This research mobilized more than 183. Furthermore. Meanwhile, nightmares could make you age new 000 adults, aged 26 to 86followed over periods ranging nightmares could make you age from a year and a half to 19 years old. Nevertheless, It was the participants themselves who indicated how frequency they were nightiemard. according to four time landmarks: never, rarely, several times a month or several times a week. They were then followed in time so that researchers can analyze their life expectancy.

People who declared that they have nightmares at least once a week presented A risk three times higher to. die before 70 years than those that rarely made it. A statistically strong association. which has remained relevant even after having controlled other conventional risk factors (smoking, obesity, physical activity, diet, etc.).

To better understand this link, researchers have crossed results with organic aging indicators. Two tools have been used for this: the length of the telomeres (these DNA segments located at the end. nightmares could make you age new of the chromosomes. which shorten with age). and more recent “epigenetic clocks”, which estimate the nightmares could make you age biological age from DNA methylation profiles. The latter indicate how “chemical marks” on our DNA activate or deactivate certain genes, a bit like switches.

After analysis, what came out is that the people who were most prone to regular nightmares were older, biologically speaking. By dint of being prey to these unpleasant night experiences, Their organization has aged faster.

Why do nightmares damage the body?

How to explain this phenomenon? The study advanced two main tracks. The first concerns acute stress induced by nightmares. These episodes often cause sudden awakenings, accompanied by an influx of cortisol (the stress hormone). A chronic excess of cortisol ends up using the organism: acceleration of the aging of cells. weakening of the immune system, metabolic disturbances, etc. In the long term, these side effects nightmares could make you age new inherent in cortisol peaks can start life expectancy.

The second hypothesis envisaged is a little more earth-to-earth. understandable for those nightmares could make you age who are not necessarily comfortable with the medical vocabulary. The night is the moment when our organism is repaired: it’s a bit like your body carried out complete maintenance. While you sleep, he takes the opportunity to regenerate cells, consolidate memory, balance hormones and strengthen the immune system.

By disturbing sleep cycles, especially deep sleep, nightmares would prevent the body from activating these maintenance functions. By sleeping less deeply. the body offers itself a less complete regeneration. struggles to clean its cellular waste and becomes a more favorable terrain for chronic inflammation and dysfunctions of its metabolism.

However. this work is not enough to assert loud. clear that The nightmares “cause” directly An acceleration of aging or faster death. What the researchers have identified is nightmares could make you age new a correlation, not a cause and effect link. It would take additional research to make sure it fully. Nevertheless. nightmares. or rather their frequency, nightmares could make you age must be estimated now as Subjective databut strongly correlated with health indicators, They, perfectly objective.

• Having nightmares could be linked to accelerated cell aging and, potentially, to a risk of early mortality.
• This study suggests that bad repeated dreams could disrupt the organism’s night repair processes and increase biological stress.
• It is for the time being an observed correlation, requiring additional research to confirm a cause and direct cause link.
