It sounds paradoxical because drinking coffee enhances alertness, but sometimes you feel unbearably tired.
Caffeine, the main active ingredient in coffee, is well-known as an energy booster, attention-booster, and alert. But long-term accumulation also backfired.
Since caffeine is also a drug, that means it can affect each of us differently, depending on our consumption habits and genes.
Scientists say, there is the opposite effect of caffeine is to put pressure on sleep. In other words, coffee causes you to fall asleep later than your body’s established biosynthesis.
But once the caffeine runs out, the body has a very high demand for sleep and you have to give it back, and the only way is to go to sleep.
However, there is a complicated problem that the more coffee we drink, the more our bodies get used to the caffeine and the stronger the resistance to sleep. And this strongly affects sleep and leads to fatigue.
If you often rely on coffee to improve your alertness, you’re going to add to your body that things get much worse in the long run. Therefore, the more cups of coffee you add, the more negatively affected sleep will be.
The caffeine in coffee can also cause blood sugar to spike or lead to dehydration, both of which can make us feel more tired.
Scientists say, if you drink a cup of coffee and suddenly feel tired, the best solution is not to drink more coffee. And temporarily stop drinking for a few days to let your body get rid of the caffeine.
And if you feel caffeine is no longer giving you energy, taking a nap, exercising, or sitting outside and being exposed to natural light can give you the most natural energy boost.
Sufficient sleep and physical activity are solutions to problems with increasing strength, attention, and good sleep. And coffee is only considered as a support drink when it is useful when the spirit is comfortable, the mood is happy but does not depend on it every day.
Excessive coffee consumption may increase dementia rates
Coffee may be the perfect morning drink, but a new study shows that drinking too much coffee can affect our brain health over time.
Coffee is a very popular beverage worldwide, containing caffeine which is a central nervous system stimulant. In a study with 398,646 participants from the Biobank in the UK, high coffee consumption (more than 6 cups of coffee per day) was associated with smaller total brain volume and a 53% higher rate of dementia…
New research from the University of South Australia shows that too much can affect brain health over time.
Dr. Kitty Pham, University of South Australia (UniSA) research team leader, said: “This is the most extensive investigation yet into the link between coffee, brain volume measurements, dementia risk and risk. stroke risk – this is also the largest study looking at brain volume imaging data and a range of confounding factors.”
“Taking into account all possible permutations, we consistently found that more coffee consumption was significantly associated with reduced brain volume. Basically, drinking more than 6 cups of coffee a day can put you at risk of brain diseases like dementia and stroke,” said Dr.
The findings indicated an inverse linear association between regular coffee consumption and total brain gray matter, white matter, and hippocampal volume. In addition, consuming at least 6 cups of coffee per day led to an almost 53% higher risk of cognitive decline compared with those who drank only 2 cups per day.
According to the European Food Safety Authority, we should drink 400mg of coffee per day, at most about 4-5 cups, for pregnant women should limit to a maximum of 200mg per day.
According to the Centers for Disease Control and Prevention (CDC), dementia is a degenerative brain condition that impairs the ability to remember, think, or make everyday decisions.
An estimated 5 million adults age 65 and older in the United States had dementia in 2014, and that number is expected to reach nearly 14 million by 2060.
