Beneficial Effects of Caffeine

in #life6 years ago

Caffeine is a stimulant to the body and is consumed by over 80 percent of the world's population on a daily basis. The body absorbs caffeine within 45 minutes after ingestion, and the effects of this stimulant are diminished after three hours and eventually excreted by the body leaving no accumulation. Caffeine has been researched as good, bad, and indifferent regarding its effects on the body. Recent research indicates that caffeine is beneficial in moderate doses. The Mayo Clinic indicates this to mean up to four cups of coffee a day or 300 milligrams.

PHYSICAL HEALTH BENEFITS

Caffeine targets the central nervous system, stimulates the cardiovascular and digestive system and is known for alleviating mental fatigue. The result of caffeine on the central nervous system is mood elevation, alertness, increased focus and cognitive clarity. Caffeine is also credited for aiding with metabolic functioning and is one ingredient used in weight loss supplements. Caffeine is touted as an aid for increasing energy, which influences fat burning. Additionally, the diuretic effect of caffeine prompts frequent elimination of waste from the digestive system. Caffeine has also shown a protective effect against heart disease when used daily in moderation. However, the type of drink containing caffeine is a consideration as well as pre-existing medical conditions. It is recommended to speak to a physician before utilizing caffeine as a regular health supplement.

MENTAL HEALTH BENEFITS

Caffeine increases the feel-good neurotransmitters in the brain, also known as dopamine. The pleasure center of the brain is impacted by the level of dopamine present. Caffeine stimulates the dopamine receptors allowing for improved emotions, bursts of energy and feelings of optimism. Many people who start their day with a cup of coffee tend to be more alert, willing to take on the challenges of the day and have a positive attitude. A study reported by the "American Physiological Society" regarding caffeine's influence on mood concluded that students who used caffeine prior to attending university lectures reported enhanced mood, mental clarity and willingness to participate versus students who did not use caffeine prior to lectures.

ADDITIONAL BENEFITS

Although caffeine has gotten a bad reputation over the years, current research is showing that there are several benefits of use when caffeine is ingested in moderation. The key to caffeine remaining beneficial is not creating a dependency on the stimulant and knowing how much is too much. Additional benefits of caffeine use include pain relief, increased acidity in the stomach that aids in medication absorption, headache relief and wakefulness.
