The Best Sleeping Position to Prevent Alzheimer’s and Memory Loss
In a phenomenon that has astonished scientists and consumers alike, recent studies have revealed a strange link between reducing caffeine consumption and increasing dream clarity.
Thousands around
the world report experiencing very realistic dreams
just days after reducing their consumption of coffee and stimulant drinks. This mysterious phenomenon raises profound questions about the effect of caffeine on the mechanism of sleep and dreams.
Experts confirm that it is related to "sleep regression", where the brain enters a state of deep sleep to compensate for previous deprivation, which increases the dream stage by up to 30%.
What is striking is that
these dreams are rich in details, colors, and sequential events, as if the scenes are vibrant with life. Some people describe it as a cinematic experience inside their minds, while others find it disturbing due to its extreme realism.
Researchers advise coffee lovers
who want to experience this unique phenomenon to gradually reduce caffeine while maintaining body hydration and exercise. They also emphasize that this experience varies from person to person, and may be a gateway to discovering new secrets about the human mind during sleep.
Caffeine and its effect on sleep
Caffeine is a stimulant that makes us feel alert and energetic. It works by blocking a chemical in the brain called adenosine, which is responsible for making us sleepy.
During the day
while we are awake and active, adenosine gradually accumulates in the brain
and by evening, this accumulation helps us feel the desire to sleep.
During sleep
- adenosine is eliminated
- so we wake up in the morning
- refreshed, ready to start the cycle again.
When we consume caffeine
whether from coffee, tea, soft drinks, or even chocolate, it blocks adenosine signals. This means that we do not feel sleepy even though adenosine is present in the brain. But when the effect of caffeine wears off, we may feel what is called a "caffeine crash", that is, a sudden increase in the desire to sleep.
Caffeine remains in the body for a period, with a half-life ranging from three to six hours. This means that half of the caffeine you consumed may remain active in your body after this period, affecting your ability to sleep.
If you have a cup of coffee in the afternoon
you may find it difficult to sleep at night, or your sleep may be disturbed.
Research shows that caffeine
especially when consumed late in the day, reduces sleep quality, and particularly affects deep sleep (non-rapid eye movement sleep - NREM), which is the part necessary to feel comfortable and refreshed.
Although direct research on
the effect of reducing caffeine on dream clarity is limited, there is a logical connection we can explore. Many people notice that their dreams become more vivid or strange a few days after reducing caffeine, and this is due to how caffeine affects our sleep, and how sleep relates to our dreams.
Caffeine
can reduce overall sleep duration
- and increase nighttime awakenings
- especially if taken late.
- When we reduce caffeine
the body begins to "refresh"
which means we may get deeper and longer sleep. This leads to an increase in
rapid eye movement (REM) sleep, the stage in which dreams occur.
During REM sleep
- the body is relaxed
- while the brain is very active
- allowing dreams to be more detailed and vivid.
In addition
REM sleep is the stage from which we often wake up during the night.
- If we wake up during this stage
- we are more likely to remember our dreams
- because they are "fresh" in our memory.
So, when we reduce caffeine, we may increase REM sleep periods
which means more opportunities to experience and remember lucid dreams.
However
we must keep in mind that sleep and dreams are complex. Not everyone can experience vivid dreams after reducing caffeine, and this effect may be temporary, lasting only a few days or weeks.
Benefits of
caffeine and the importance of timing
Caffeine is not just a substance that makes us feel alert
it has many benefits.
For example
- studies have shown that coffee drinkers may be less likely to suffer
- from depression, and caffeine has been linked to
- a lower risk of diseases such as Parkinson's.
Coffee contains B vitamins
and antioxidants, making it part of a healthy diet.
If you love caffeine and don't want to give it up completely, the key is timing.
Try to avoid caffeine for at least eight hours before bed
and avoid large doses 12 hours before bedtime.
For example
if you usually sleep at 11 p.m., try not to consume caffeine after 3 p.m., and reduce large amounts after midday. This timing can help improve the quality of your sleep, which may lead to an increase in REM sleep and possibly clearer dreams.
