We have good news for lovers of America’s two favorite mood-altering substances, caffeine and marijuana: Caffeine may enhance a pot smoker’s high.
The downside is that caffeine can also increase the chance of becoming addicted to cannabis.
If you often find yourself going to a room in your house only to forget what you’re meant to do, or talking about a movie character you’ve seen so many times but can’t remember the name of, then one thing is going on.
It’s so easy to dismiss these as simple moments of forgetfulness. But if this happens a lot, then it may be your body sending you a signal to do something and beat brain fog.
The writer, Dan Charles, bought a 4-ounce bag of caffeine and said it had as much caffeine as 1,000 tall Starbucks lattes. He said this caffeine was created in coffee beans on a hillside in the tropics. “Slowly and quietly, driven by the energy of sunlight, it formed inside coffee beans hanging on thousands of trees, most likely in Brazil or Vietnam,” Charles wrote.
“Those beans were harvested, loaded on ships bound for the port of Houston, Texas, and ended up at a factory within sight of downtown Houston: Atlantic Coffee Solutions. It’s owned by one of the world’s largest coffee traders, ECOM Agroindustrial Corp., which is based in Switzerland.”
Coffee was so important in wartime America during World War II that the government rationed it briefly so soldiers could get enough. Coffee was one of four staples for Civil War soldiers, along with beans, beef and hardtack. After Boston Tea Partiers dumped that tea in the harbor during the Revolution, coffee drinkers were considered patriotic.
Coffee can give a soldier the alertness he needs in times of prolonged sleep loss or during dangerous combat situations.
Sages and philosophers from various world traditions have counseled “Everything in moderation,” and, stated another way, “Nothing in excess.” These aphorisms apply to caffeine, too, because too much of this otherwise beneficial chemical can cause insomnia, nervousness, muscle tremors and stomach upset.
Caffeine can boost athletic stamina and speed so much that the International Olympic Committee once limited how much of it Olympic athletes could take. Caffeine was categorized as a performance-enhancing substance.
The regular athlete might not be able to run a marathon in 2:02.57 like Dennis Kimetto, but maybe after an invigorating jolt of java you can one run just a little bit quicker and burn some fat in the process. Caffeine can improve performance by 1.5 to 3 percent, recent studies show. And the amount needed to give the boost is no more than that in an 8-ounce cup of coffee or an energy drink or two.
As a medical student, going through residency can be a character-building experience. Night shifts – or floats – can mean long hours of staying awake and alert. And when we say long hours, we mean 20 to 40 hour shifts, sometimes nights in a row. Here are some tips to survive medical residency… alive and kicking.
When people talk about having “a cup of coffee,” they don’t necessarily mean 8 ounces (236 milliliters). For example, many people go for the large size of coffee at McDonald’s restaurants and Starbucks, at 20 ounces (591 milliliters). Or at home, they may have a 12- to 16-ounce mug.
So when you read guides online that say an 8-ounce cup of drip java has about 163 mg of caffeine, you can more than double the amount of the stimulating chemical for a 20-ounce size. Drip coffee is the kind that drips through a filter to produce that cup or mug of the elixir that so many people say they can’t start their day without.
The question is of great concern because in the United States, drowsy driving kills an estimated ~800 people a year in 90,000-some accidents, says the National Sleep Foundation in its article How To Stay Awake On The Road .
The AAA says the numbers are even more alarming than what the NSF announced:
The AAA Foundation for Traffic Safety estimates that an average of 328,000 annual crashes in the U.S. involve a drowsy driver, including 109,000 that result in injuries and 6,400 that involve a fatality. The National Transportation Safety Board also included “reduce fatigue-related accidents” on its 2017-2018 Most Wanted List of the 10 most critical changes needed to reduce transportation accidents and save lives. 
As we said in this Viter Energy blog  about the work-life balance, it's a good idea to simulate your commute to work. You don't have to drive in to work, so instead take a walk around the block just before your workday starts and just after it ends. Send yourself a psychological signal.
And if you can avoid it, do not work after your walk around the block. Don't check work email. Don't answer calls from co-workers unless you really need to talk to them (or they are friends you socialize with).
Clinical psychologist Kelcey Stratton of Michigan Health Blog  has some sound advice on finding the right time to work:
If you’re a morning person, try to schedule important work and meetings during the first half of the day. Others may peak with energy in the afternoon. Depending on the type of job you have, try to maximize on these levels as you can.
The first bit of advice is to get up from the computer, turn off your phone, and go get some exercise, do something recreational, prepare a meal, or something other than work, on the same schedule as you did when you worked at the brick-and-mortar office.
If you used to get off at 5 p.m., quit working at home at 5. You might need to check email or prepare a report later that night, but be sure to get away from all electronic communications and computing devices for a while.
Another big tip is to take your coffee breaks and lunch breaks on the same schedule, or at least be sure to take them at some point. Do not skip your favorite part of the day!
