Do you drink coffee everyday? does it rejuvenate and energize you? Are you a sucker for the hot piping cup of Joe? Is coffee your middle name for breakfast? Do you crave for coffee at the start of the day?
For many of us, kick-starting a day is incomplete without a cup of black espresso! The heat of the coffee helps give you comfort and warmth and is a treat for coffee aficionados the world over. Coffee originally was grown in Africa and South America.
The beans now are crushed and ground in the United States to cater to a growing clientele in North America. America does really run on coffee! You will be surprised to know that 54% of Americans over the age of 18 drink an average of 3.1 (8 oz) cups of coffee per day.
With many varieties donning the coffee parlour shelves, here are a few things coffee lovers can take heart from:
1. Increase in metabolism.
This is good news for those of you that follow a good workout routine. With an exercise regimen in place, you can start off with the caffeine from the coffee and naturally boost the energy levels that help rev up your health and spirits. In a study conducted by the Journal of Applied Physiology found that endurance athletes who had a cup of coffee after exercise had a 66 per cent increase in muscle glycogen that helped replace the deficient energy levels.
In a study recently logged in the National Library of Medicine, researchers observed that – a single-dose oral administration of 100 mg caffeine increased the resting metabolic rate of both lean and postobese human volunteers by 3-4% (p less than 0.02) over 150 min and improved the defective diet-induced thermogenesis observed in the postobese subjects.
2. Experience confusion, headaches, and irritability.
No doubt, a cup of strong coffee gives you a mental boost and helps a lot especially when you are busy with important work. However, if you continue to do this every day, you will soon be addicted to caffeine. Because coffee normally binds to the adenosine receptors in the brain. Adenosine is what builds up sleep pressure and creates tired sensation and with excess coffee consumption, our body tends to create more adenosine receptors, which then no longer are bound by the caffeine in coffee.
As a result, you will crave for more coffee just to counter the withdrawal symptoms including anger, irritation, low energy, confusion, headache, mental exhaustion. According to the American Heart Association, “Caffeine-habituated individuals can experience ‘caffeine withdrawal’ 12–24 hours after the last dose of caffeine. It resolves within 24–48 hours. The most prominent symptom is a headache.
3. Caffeine gives you jitters.
If you are not used to it, caffeine can affect the nervous system and give you jitters. People with an anxiety disorder and sleep problems having coffee regularly can experience jitters and may worsen the health. Excess coffee consumption can negatively affect your daily routine. So, keep a check on coffee intake to prevent the tolerance buildup.
4. Excess caffeine causes nausea and vomiting.
There are various acids found in coffee that contribute to the taste of your brew. The acidity in coffee, especially when you drink coffee on an empty stomach every day, may irritate your stomach lining, and cause feelings of nausea and vomiting.
5. Increase brain alertness.
Caffeine in coffee has a positive effect on mental alertness, attention, mood and concentration. What’s more surprising is the ability of coffee to enhance memory retention. Coffee is able to increase mood and reaction times in humans with an increase in memory and alertness too.
According to a study published in Nature Neuroscience, Caffeine enhanced performance 24 hours after administration. Based on findings researchers concluded that caffeine enhanced consolidation of long-term memories in humans. That said, excessive coffee consumption is not necessarily better. You may not always experience an increase in productivity.
As per one study published in the Experimental and Clinical Psychopharmacology journal, one serving of coffee drastically improves focus and mental stamina ten minutes after consumption.
According to cardiologist Dr. Steven Reisman, director of the New York Cardiac Diagnostic Center, caffeine in coffee increases your brain activity by blocking adenosine. He explained to The List that caffeine also increases the neurotransmitters such as dopamine and norepinephrine, which can reduce tiredness and increase mental alertness. Thus, coffee drinkers have a good level of happy hormones in their blood system.
