Is Coffee Making Your Anxiety Worse?
Jolts of energy from caffeine
The explanation behind the surge of energy you get from drinking coffee is: caffeine blocks the receptors that are meant to be for adenosine.
Adenosine plays a number of bodily functions, but during our bodies' waking hours it builds up in the receptors which causes us to feel sleepy and less alert. So, when we intake caffeinated drinks, the caffeine blocks the receptors that are meant for the adenosine to build up and also could trigger the release of adrenaline.

Coffee in moderation
Coffee was once believed to be a possible carcinogen. However, the evidence is consistent that coffee in moderation is associated with a lower risk of mortality.
Research found moderate ...
The way coffee is prepared matters
- Roasting reduces the number of chlorogenic acids, but other antioxidant compounds are formed.
- Instant coffee may not have the same health benefits.
- The oil in boiled coffee has cafestol and kahweol, compounds known to raise LDL, the bad cholesterol, and slightly lower HDL, the good cholesterol. However, the clinical significance of such small increases in cholesterol may be questionable.
Coffee and caffeine
- A typical 12-ounce serving of drip coffee has 200 milligrams of caffeine.
- Instant coffee has 140 milligrams of caffeine.
- Espresso has the highest concentration of caffeine, 70 milligrams per one-ounce shot, but is consumed in smaller quantities.
- Brewed decaf has caffeine too - about 8 milligrams.
- Some people have a genetic variant that slows their metabolism for caffeine and keeps them awake deep into the night.

How Coffee Affects Us
- When we have coffee, it gets absorbed in our gut as well as in our bloodstream. As the chemical is soluble in water and fat both, it can easily enter the brain.
- Adenosine, a molecule present in our brain which is remarkably similar to caffeine, is responsible for a feeling of tiredness.
- Caffeine acts like a doppelganger and is able to fit in the receptors that adenosine fits, preventing any tiredness to occur for a few hours.
- The surplus adenosine now floating in the brain signals that adrenal gland to produce and secrete adrenaline, which is also a stimulant.
Addicted To Coffee
The chemistry of the brain changes when a person takes a regular intake of caffeine, as it grows more adenosine receptors.
Eventually, it takes more caffeine to feel the effects, and as there are now more receptors, not having a stimulant results in ‘caffeine withdrawal headache’ and other symptoms due to the original molecule connecting to the increased number of receptors in the brain.

Biohacking
It can be described as citizen or do-it-yourself biology. For many, this consists of making small, incremental diet or lifestyle changes to make small improvements in your hea...
Popular types of biohacking
- Nutrigenomics focuses on how the food you eat interacts with your genes and how different nutrients affect how you feel, think, and behave.
- DIY biology: Biohackers with education and experience in scientific fields share tips and techniques to help non-experts conduct structured experiments on themselves.
- Grinder: Grinders seek to become “cyborgs” by optimizing their bodies with a combination of gadgets, chemical injections, implants etc.
Biohacking and safety
- Some forms of biohacking may be safe. For example, taking certain supplements or making changes to your diet can be safe. Even some body mods, like RFID implants, may be safe when overseen by a medical professional.
- Some biohacking methodologies border on the unsafe or even illegal. DIY bio and grinder sometimes center around experiments that aren’t considered safe or ethical in research facilities.
