The effects of coffee (and caffeine) on the mind and body

Is drinking coffee healthy and should I be drinking 1, 2 or 10 cups? The effects of coffee (and caffeine) on the mind and body differ between people; this is partly from how different people metabolize coffee.. But it also has to do with your body’s amazing ability to adapt (read: become more tolerant) to long-term caffeine use. Many people who start drinking coffee feel the effects a lot more than people who have coffee every day.

Here’s a list of these effects (that usually decrease with long-term use):

  • Stimulates the brain
  • Boosts metabolism
  • Boosts energy and exercise performance
  • Increases your stress hormone cortisol
  • Dehydrates

So, while some of these effects are good and some aren’t, you need to see how they affect you and decide if it’s worth it or not.

Coffee and health risks

There are a ton of studies on the health effects of coffee, and whether coffee drinkers are more or less likely to get certain conditions.

Here’s a quick summary of what coffee can lead to:

  • Caffeine addiction and withdrawal symptoms (e.g. a headache, fatigue, irritability)
  • Increased sleep disruption
  • Lower risk of Alzheimer’s and Parkinson’s
  • Lower risk of developing type 2 diabetes
  • Lower risk of certain liver diseases
  • Lower risk of death (“all-cause mortality”)
  • Mixed reviews on whether it lowers risks of cancer and heart disease

Many of the health benefits exist even for decaf coffee (except the caffeine addiction and sleep issues).

NOTE: What’s super-important to note here is that coffee intake is just one of many, many factors that can affect your risks for these diseases. Please never think regular coffee intake is the one thing that can help you overcome these risks. Being health-conscious means knowing to eat a nutrient-rich whole foods diet, reducing stress, and getting enough sleep and exercise are all critical things to consider for your disease risk. It’s not just about the coffee.

Should you drink coffee or not?

There are a few things to consider when deciding whether you should drink coffee. No one food or drink will make or break your long-term health.

Caffeinated coffee is not recommended for:

  • People with arrhythmias (e.g. irregular heartbeat)
  • People who often feel anxious
  • People who have trouble sleeping
  • People who are pregnant
  • Children and
  • Teens

If none of these apply, then monitor how your body reacts when you have coffee. Does it:

  • Give you the jitters?
  • Increase anxious feelings?
  • Affect your sleep?
  • Give you heart palpitations?
  • Affect your digestion (e.g. heartburn, etc.)?
  • Give you a reason to drink a lot of sugar and milk?

Another consideration is have you been slowly but gradually increasing the cups of coffee you have during the day due to what you were having just not doing the job anymore? This increased reliance on coffee can be a problem as with any drug using coffee to increase your productivity can lead to you reducing relaxation and down time which is essential for good health. Not just for your body but also for your mind.

Depending on how your body reacts, decide whether these reactions are worth it to you. If you’re not sure, I recommend eliminating it for a while and see the difference. I think the key is to decide can I do without it or am I using it as a crutch to keep me awake and functioning, so I can get through my day?
