The good, the bad and…the Cortisol

The good, the bad and…the Cortisol

Cortisol is one of the steroid hormones and it is made in the adrenal glands. Secretion of the hormone is controlled by the hypothalamus, the pituitary gland and the adrenal gland. In a nutshell, Cortisol it’s notably known to be the “the stress hormone” that’s for a good reason indeed.

The cortisol, once released, can be received by most of the bodily cells, so it can affect many different functions in the body.

Cortisol can do really a lot of positive things to our body, such as:

-helping control blood sugar levels

-regulating metabolism

-reducing inflammation

-and much more…

In women, cortisol also supports the developing fetus during pregnancy. If so, why cortisol is commonly considered as “bad” and often included among the stress response biomarkers?

All of its functions make cortisol a crucial hormone to protect overall health and well-being under normal circumstances, that’s really true.

On the other side, our lifestyle and daily demands are constantly altering or unbalancing the cortisol levels in our system, and here comes the bad side of cortisol.

Bear in mind that cortisol is also the major age-accelerating hormone. Cortisol is able to weaken immune function, reduce bone formation through calcium absorption, and create a loss of collagen (which weakens support in muscles, tendons, and joints).

Cortisol also counteracts insulin, contributing to high blood sugar and that’s why cortisol is also linked to weight gain and storing of belly fat. In a nutshell…we don’t want to interfere with the normal functions of our body, and in particular with the levels of cortisol inside our personal living system. But, what can be considered as “normal” and under which circumstances?

Variability of Cortisol levels

In a ‘normal’ situation (i.e. you are not chased by a lion or undergoing any similar life threatening situation…) and for a person not suffering of any particular disease, Mr. Cortisol’s typical day can be schematized as follows:

corti1

    Cortisol production is at its peak around 30 minutes after waking up. And this is actually needed, to ensure a correct and fresh waking up (you can kick the adrenals up drinking some lemon water with a pinch of salt, it’s worth the try, or sun exposure, that will help as well).

    Then, the levels of cortisols gradually fade to a minimum before going to sleep, so reasonably low levels of cortisol in the evening are more than welcome.

    Beside that, we all know that during the day we receive external stimuli or we can face events that cause us to undergo “stressful” situations, and so a series of chemical reactions start inside our body. One of the consequences of this chemical production is to have peaks of cortisol when we don’t want.

    corti2

      When a stressor occurs, in fact, our limbic system, a more primitive part of our brain, instantly responds to danger and thus we face a “fight or flight” response.

      In the old times we, as humans, used to consider a stressor any life threatening situation (see lion above) so this primordial reaction is something we inherited from our ancestors, and it’s not so bad, in line of principle.

      Advertising

      But nowadays we rarely have the same type of life threatening situations inducing a “fight or flight” response: the predatory attacks of the new era are completely different things, such as demanding tasks, losing our keys, starting a new company, or in-laws coming for Thanksgiving.

      The problem is that, in terms of chemical reactions, the above situations are considered pretty much the same from our inner body.

      A big difference in today’s world, though, is represented by the frequency and the intensity of the stimuli. Something occurring rarely in the prehistoric era (i.e. predator attack) is now occurring more frequently, almost on every day, with less intensity but still effective in terms of body reaction to the stimulus.

      In the long run, the fight or flight stress response is not even turning off, thus, the cortisol levels are not following the normal path as they should be and they remain relatively high during the evening, impacting consequently on the quality of our sleep and body recovery.

      In addition to that, there are other elements and situations inducing the release of cortisol in our organism, and these are, again, associated with the lifestyle of the modern era. Some examples of conditions releasing cortisol are:

      -Staying up late

      -Poor sleep

      -Caffeine intake

      -Poor diet

      -A non properly planned workout routine

      Advertising

      -many others…

      So, what to do to keep cortisol levels under control?

      6 things to do to manage cortisol

      Spending time in Theta

      No, it’s not the name of a fancy island or a new planet on another constellation. I am talking about brain waves, and in particular about the ones linked to the brain state of REM sleep (dreams), lucid dreaming and advanced levels of meditation.

      To cut it short: in a state of very deep relaxation our brain produces waves at a slow frequency of 4-7 cycles per second. This stage it’s extremely calming and it’s really body-restoring. Factors like high levels of stress, overconsumption of caffeine during the day and the faced-paced lifestyle could have an impact on our transition to deep sleep.

      Acting on stress reduction, with meditation, as example, will consequently drop down the cortisol levels.

      Drink milk (or, better, its peptides)

      In various studies, the administration of milk peptides resulted in a net reduction in cortisol of -20.69% when compared with the placebo group. It turns out that nutrients found in cow’s milk (the bioactive peptides) exert a sedative effect on the brain. This is also the reason why a warm glass of milk helps to fall asleep, since generations.

      Eat better

      I know, this ‘magic’ solution seems to be everywhere, but it’s true: we are what we eat, and an anti inflammatory diet, eating whole food, would help lowering cortisol levels.

      Extensive research has shown that a high quality fish oil like cod liver oil or krill oil, rich in omega-3s and fat-soluble vitamins, can effectively lower cortisol levels that were increased by mental stress.

      Sleep and Recovery

      Sleep deficit has been linked to elevate cortisol levels (and for prolonged hours) in helicopter pilots on 7-day duty for emergency medical services. Although the test has involved a particular category of workers (and work related stress), the association between lack of sleep and cortisol is still valid: so hit the sack early, or take a nap.

      Switch to tea

      Caffeine elevates cortisol levels, so drink your coffee, but try to switch to tea or decaf after 2pm or anyway at least 6/8 hours before bedtime, your body will thank you.

      Advertising

      Eat more fruit

      Oranges and grapefruits, in particular. These 2 citrus fruits are rich in vitamin C, which has been linked to reduced cortisol levels. A study in 2001 examined the effects of supplemental vitamin C on high cortisol levels brought about by physical stress in marathon runners. Ultramarathon runners were given 500 mg a day of vitamin C, 1500 mg a day of vitamin C, or a placebo seven days before a marathon, the day of the race, and two days after the race. Researchers found that athletes who took 1500 mg per day of vitamin C had significantly lower post-race cortisol levels than those taking either 500 mg a day or placebo.

      How to Overcome Boredom

      How to Overcome Boredom

      Have you ever been bored? Restless? Fidgety? In need of some inspiration?

      I have a theory on boredom. I believe that the rate of boredom has increased alongside the pace of technology.

      If you think about it, technology has provided us with mobile phones, laptops, Ipads, device after device – all to ultimately fix one problem: boredom.

      What is Boredom?

      We have become a global nation that feeds on entertainment. We associate ‘living’ with ‘doing’. People now do not know how to sit still, and we feel guilty when we are not doing anything. Today, inactivity has become the ultimate sin.

      You might not realize it, but boredom stimulates a form of anxiety and stress. It evokes an emotional state that creates frustration and feeds procrastination.

      Advertising

      It’s a desire to be ‘doing something’ or to be ‘entertained’ – it’s a desire for sensory stimulation. What it boils down to is a lack of focus.

      If you think about those times when you’re bored, it’s usually because you did not know what to do. So, indecision also plays a big part.

      When we are focused on what’s important to us and what we want to achieve, it’s pretty hard to be bored. So, one answer to boredom is to become focused on what you want.

      Sometimes It’s Good to Be Bored

      If boredom is a desire for sensory stimulation – then what’s the opposite of that? To be content with no stimulation – in other words – to enjoy stillness.

      Sometimes, it’s not boredom itself that causes the frustration but the resistance to doing nothing.

      Advertising

      Think about it. What would happen if you were to ‘let go’ of the desire to be entertained? You wouldn’t be bored anymore, and you will feel more relaxed!

      In my experience, it’s often the most obvious, simplistic solutions that are the most powerful in life. So, when you’re bored, the easiest way to combat this is to enjoy it.

      It may sound weird but think of ‘boredom’ as a form of ‘relaxation’. It’s a break from the constant stimulation that 21st-century living provides – constant TVs, mobile phones, radios, internet, emails, phone calls, etc.

      Who knows, maybe ‘boredom’ is actually good for us?

      Next time you’re ‘feeling bored’ instead of feeding the frustration by frantically looking for something to do, maybe you can sit back, relax, and savor the feeling of having nothing to do.

      Advertising

      In this article, I’ll share with you my 3-step strategy on how to overcome boredom.

      3-Step Strategy to Overcome Boredom

      1. Get Focused

      Instead of chasing sensory stimulation at random, focus on what’s really important to you. Focusing on something important helps prevent boredom because it forces you to utilize your time productively.

      You should ask yourself: what would make good use of your time? What could you be doing that would contribute to your major goals in life?

      Here are a few ideas:

      • Spend some time in quiet contemplation considering what’s important to you.
      • Start that creative project you’ve been talking about for the last few weeks.
      • Brainstorm: think of some ideas for new innovative products or businesses.

      2. Kill Procrastination

      Boredom is useful in some ways because it gives you the energy and time to do things. It is only a problem if you let it. But if you use it to motivate yourself to be productive, then you can more easily overcome boredom.

      Advertising

      So, the next time you’re bored, why not put this good energy to use by ticking off those things that you have been meaning to get done but have been too busy to finish? This also presents a great time for you to clear your to-do list.

      Here are some ideas:

      • Do some exercise.
      • Read a book.
      • Learn something new.
      • Call a friend.
      • Get creative (draw, paint, sculpt, create music, write).
      • Do a spring cleaning.
      • Wash the car.
      • Renovate the house.
      • Re-arrange the furniture.
      • Write your shopping list.
      • Water the plants.
      • Walk the dog.
      • Sort out your mail & email.
      • De-clutter (clear out that wardrobe).

      3. Enjoy Boredom

      If none of the above solutions work, then you can try a different approach. Don’t give in to boredom and instead choose to enjoy it. This doesn’t mean allowing yourself to waste your time being bored. Instead, think of it as your time to relax and re-energize, which will help you be more productive the next time you work.

      Contrary to popular belief, we don’t need to be constantly doing things to be productive. In fact, research has shown that people are more productive when they take periods of rest to recharge.[1] Taking breaks once in a while helps boost your performance and can help make you feel more motivated.

      So, take some time to relax. You never know, you might even like it.

      Final Thoughts

      Learning how to overcome boredom may be difficult at the beginning, but it can be easier if you make use of some techniques. You can start with my 3-step strategy on how to overcome boredom and work your way from there. So, ready your mind and make use of these tips, and you will be overcoming boredom in no time.
