Here's How a Cup of Joe Can Shape Your Body's Cortisol Response

Are you a dedicated coffee enthusiast, savoring the ritual of starting your day with a piping-hot mug of caffeinated deliciousness? Turns out you really don't have to worry about coffee jumpstarting or shoving your morning “cortisol awakening response” into overdrive, particularly if you've been drinking coffee for more than five days — which defines most of us, right?

If you're anything like me, the comforting embrace of that daily cup of joe (I recommend trying the organic medium or dark roast by Kion) sparks curiosity about the intricate relationship between caffeine and its effects on your body, especially concerning the stress hormone cortisol.

Caffeine, as you likely know, can kickstart cortisol secretion, whether you're chilling out or under mental stress. The pressing question remains, “Can a person develop a tolerance to this cortisol spike with regular caffeine intake?”

To help you understand the connection, I'm delving into a captivating study that not only answers this question but also uncovers the surprising dance between your morning brew and your body's stress response.

Researchers sought answers by conducting a comprehensive double-blind, crossover trial with both men and women. Over four weeks, participants alternated between abstaining from caffeine and consuming controlled doses to measure its impact on cortisol levels.

Here's the discovery: After a five-day caffeine break, a single caffeine dose caused a significant jump in cortisol levels throughout the day. However, when participants consumed caffeine daily (300mg or 600mg per day), their morning cortisol response to caffeine practically vanished.

This pattern suggests that while the body can adapt to the cortisol-boosting effects of caffeine to some extent, this adaptation is not complete. Regular caffeine consumers might not experience the same morning cortisol spike as occasional drinkers, but they're not entirely immune to caffeine's impact on cortisol levels later in the day.

So, what does this mean for you and your coffee habit?

If you're a regular coffee drinker, your body likely adjusts to the cortisol response, particularly in the morning. But if you decide to take a break from caffeine, be prepared for that familiar cortisol surge to return after about five days — a reminder that even your daily cup of joe can have more complex effects than you might realize.

My Favorite Clean Energy Drink (With ZERO Of That Pesky Folic Acid)

In a world saturated with energy drinks promising an instant pick-me-up, the pursuit of vitality often comes at a cost — compromising your health.

This is because most energy drinks are full of synthetic folic acid, which can disrupt your body's intricate methylation process. The consequence? An insidious rise in homocysteine levels, a notorious troublemaker that doesn't just cloud your mind with brain fog but also throws your energy levels off balance. Imagine your mental clarity slipping away, your focus faltering, and the very essence of restorative sleep becoming a distant memory. You can read up more on that paradoxical issue of folic acid in energy drinks (along with many fortified grains and cereals) here. 

Choosing energy drinks loaded with synthetic folic acid isn't merely a gamble; it's akin to playing Russian roulette with your vitality — a risky bet that could compromise the core elements of your well-being.

If you've found yourself caught in the paradox of needing an energy boost but questioning the toxic ingredients in typical concoctions, you're not alone. The dichotomy between seeking heightened alertness and maintaining a health-conscious lifestyle is real, which is why I'm a huge fan of Update. This isn't just another energy drink; it's a strategic shield against the dangers lurking in typical energy boosters. It's also zero-calorie, zero-sugar, and loaded with clean ingredients like paraxanthine, L-theanine, and essential vitamins C and B12. Additionally, Update doesn't include any questionable additives or toxic ingredients like aspartame, sucralose, or coloring agents, either.

What do you drink when you need more energy? Have you looked at the label recently?
