Cortisol and Stress.

Todays post is about Cortisol and stress.

I have been reading an interesting book called ‘The Cortisol Connection’. It is about how stress and the hormone ‘Cortisol’ affect our health.

I thought I would share with you some of what I have learned.

Firstly, what is Cortisol?

Cortisol is a hormone produced by the adrenal glands, which are located near the kidneys. It’s the body’s primary stress hormone and works with certain parts of our brain to control mood, motivation, and fear.

It’s best known for preparing the body’s “fight-or-flight” instinct in a crisis. However cortisol also plays a vital role in a range of other bodily functions.

  • Manages how the body uses carbohydrates, fats, and proteins
  • Regulates blood pressure
  • Increases blood sugar (glucose)
  • Controls sleep/wake cycle
  • Boosts energy so that the body can handle stress and restores balance afterward

We have cortisol receptors in most of the cells in our body. These receptors receive and use the hormone in several ways. When the body is on high alert, cortisol can alter or shut down functions that get in the way. These might include the digestive or reproductive systems, the immune system, or even growth processes.

These functions of cortisol are very beneficial, but only for a short period of time, in very specific situations.

Then there’s Stress

Now for all of us, living in the twenty-first century brings with it a certain amount of unavoidable stress. This can mean that, sometimes, our cortisol levels can get out of balance.

In an ideal world, after the pressure or danger has passed, the body’s cortisol level should calm down. This means that the heart rate, blood pressure, and other systems will get back to normal.

But what if you’re under constant stress and the alarm button stays on?

Too Much Cortisol

Too much cortisol can derail the body’s most important functions. It can also cause a variety of health problems.

  • Anxiety and depression
  • Headaches
  • Memory and concentration issues
  • Problems with digestion
  • Trouble sleeping
  • Increased appetite and weight gain
  • Elevated cholesterol levels and blood pressure
  • Reduced sex drive

When the body is continually subjected to regular stress, this will lead to increased cortisol levels. The subsequent health problems will then create additional stress for the individual and a vicious cycle is created.

It’s about balance.

We have all heard this many times and some of us are lucky enough to get the balance just right. However it’s now scientific fact.

Stress researchers have proven that the best way of managing stress is to eat right, exercise regularly and get enough sleep.

Eat right – The scientists support what many of our grandparents have said. Eat a good blend of carbohydrates, proteins and fats, including 5 serves of fresh fruit and vegetables. In other words, a little of everything, but without the high processed ‘fast foods’.

Exercise regularly – This translates to ‘a small amount of exercise on a daily basis’, such as walking whenever possible and using the stairs. The small sessions of exercise help the body to use the energy provided by the cortisol and then calm down. Simulating a sort of a mini ‘fight or flight’ scenario.

Enough sleep – Researchers found that too little sleep heightens the stress response and keeps cortisol levels elevated. Participants who got 8 hours of sleep for a week kept cortisol levels in the normal range.

The Australian National Sleep Foundation recommends between 6 to 10 hours of sleep for adults 26-64.

 We are all living with a certain amount of stress every day and it’s important to our health that we find our own balance.

Inflammation and the Immune system

Todays post is about Inflammation,

Last week I wrote about the Immune System and how when it is compromised, we get sick. Well, this week I am going to expand on that subject.

One of the symptoms of a compromised immune system is Inflammation.

There was an article in todays Body & Soul that focused on this issue. Finally scientists are saying that Inflammation in the body is one of the major causes of illness. Many Naturopaths and practitioners of complimentary medicine have been saying this for years.

Scott and I first heard about Inflammation in the body and its relationship to illness approximately 8 years ago.

Normally Inflammation is a good thing. It’s a sign of the body’s defense system fighting infection or repairing damage. This is all well and good when our immune system is working well. However, as I mentioned last week, many of us have a compromised immune system due to the stressors we put on it.

We often suspend the body’s process of using inflammation to deal with issues. We start to feel the aches and pains and take anti-inflammatories. Therefore the body doesn’t get to complete its healing processes.

The result being that instead of only calling on our inflammatory defences when we are injured or sick, we’re increasingly triggering the response day in, day out. This creates a situation where our body is consistently emitting small quantities of inflammatory compounds. These levels are often too low to create noticeable symptoms.

There have been recent studies linking high levels of inflammation in the body with some major health problems, such as cancers and heart disease.

 So where does the inflammation come from?

Some is produced inside the body. Excess weight is a cause as fat cells excrete inflammatory substances. We also create it by not taking care of ourselves; stress causes the response as well as lack of sleep. If we soldier on with our aches and pains, ignore allergies and if we don’t look after our teeth, our levels of inflammatory chemicals rise.

Another cause is many of the foods that are a large part of the Western diet.

Foods such as sugar, alcohol, high fat meats, fried foods and refined grains cause inflammation.

 How do we reduce our inflammation?

 The good news is diet can also be used to protect us against inflammation. There is scientific evidence to show that there are foods that reduce inflammation in the body. These are green leafy vegetables, onion, garlic, herbs and spices such as ginger, turmeric and pepper. So by reducing our intake of the Pro-inflammatory foods and increasing the Anti-inflammatory foods in our diet, we are taking steps to lower the inflammation in our bodies.

This strategy along with improving our sleep, reducing our stress and getting some exercise, goes a long way to improving our immune system ability to cope.

A stronger immune system is a stronger, healthier body.

Our Immune System and how we get sick.

Todays post is about the Immune System.

This past week I have been resting, letting my body and immune system work through a virus.

This one really crept up on me. Most of us usually feel when we are becoming unwell. We feel achey, maybe get headaches or a ‘heavy head’. Usually this is what happens to me. Well, this time I didn’t see it coming.

The previous week, I had been very busy, I worked more hours than usual. I had appointments to attend and other projects to complete. I was feeling tired, but that was to be expected after my busy week. Or so I thought.

So, ending up in bed late last Sunday night with a fever, was a surprise. Not a nice one either. This got me thinking about how we get sick.

I had been quite confident that I was healthy, with a fairly good immune system. So, what let me down?

In hindsight, stress and lack of quality sleep. Not giving my body, and my immune system, enough time to recover.

The Immune System

The immune system is one of the hardest working mechanisms in the human body. What many people may not realise is that the body actually has two immune systems: the innate (or primary) system and the adaptive (or long-term) system.

When a possible threat from an illness-causing invader is detected, the innate system, is alerted to respond to the threat.

However, many people have a lowered immune system that can cause the innate system to work harder than it needs to in protecting the body.

So when that system has to work harder, we have less energy and in many cases, an overwhelming feeling of fatigue and feeling really tired.

The 4 most Common Causes of Lowered Immune System are
  1. Stress. Nearly all of us have felt the effects of stress at some point in our lives. Headaches, pounding chest pains, uneasiness and an overall tense feeling are hallmarks of stress. These factors all combine to cause the immune system to have to work harder to defend the body against threats to health.
  2. Lack of sleep.You may not realise it, but while you’re sleeping the cells in your blood that fight infections are working to keep infections at bay. So lack of sleep and fatigue can leave your defence system weak.
  3. Not enough exercise. Your body’s defences will likely not be at their best if your lifestyle is too sedentary.
  4. Improper nutrition, Fats, particularly polyunsaturated fats, tend to suppress the immune system. Also be on the lookout for the consumption of too much sugar, which can inhibit the process by which white blood cells work to destroy viruses and bacteria.

So while our immune system is struggling with keeping up with our busy lives, it is left open to attack. It now has a diminished ability to fight off the germs and viruses that can lead to colds, the flu and other threats to our well-being.

This is information that a lot of us already are aware of, however, our lives get so busy that it’s easy to forget.

It’s a shame we have to become ill to remember it all again.

 

Until the next post, take time to rest and
