Coffee may extend your life
Did you remember to drink your cup of life extending liquid this morning? A newly released study from the AARP and the National Institute of Health has found that the black gold workers slug down each day MIGHT have life extending properties.
After analyzing data collected from 400,000 people who were studied for one decade it was learned that one cup of coffee per day reduces the chance a woman will die by five percent and that a man will die by six percent.
Perhaps the most startling data released in the study is that women who consume more than four cups of coffee a day on average extend their life bar by 16 percent.
The study didn’t find any definitive results as to why coffee drinkers appear to live longer than non-drinkers.
The study also found that coffee drinkers had a lower chance of dying from heart or respiratory disease, stroke, and diabetes – as well as death from accidents or injury. However, there was no difference when it came to cancer rates.
How coffee works
Rightardia knows that coffee affects the pituitary, the master gland of the endocrine system, and causes it to release hormones.
Coffee contains methylxanthines. These alkaloids can increase cognitive abilities, improve energy, enhance well-being, and increase arousal and alertness.
Serotonin is involved in mood and appetite regulation; gamma-aminobutyric acid (GABA) typically inhibits neuronal activity to cause relaxation and sleep; and acetylcholine is involved in muscle contraction.
Caffeine intake has been shown to increase the receptors of serotonin (26-30% increase), GABA (65% increase), and acetylcholine (40-50%).
This may elevate mood and increase the feeling of energy after a coffee. Caffeine inhibits the release of GABA, which contributes to our feeling of alertness.
The adrenal glands secrete hormones such as epinephrine,norepinephrine, dopamine and cortisol.
Epinephrine, or adrenaline, increases respiration rate, heart rate and blood pressure; while cortisol frees up stored glucose. Glucose is needed in greater amounts during times of perceived stress.
Studies in humans have shown that caffeine increases cortisol and epinephrine at rest. The levels of cortisol after caffeine consumption are similar to those experienced during an acute stress.
Drinking coffee, in other words, mimics the body's response to stress conditions.
