Sleep and why most of us need more of it!

sleep-deprivation

Today’s blog post is about sleep – one of the most underrated things we can adjust to hinder or help our fitness goals and fat loss.

SLEEP 101 – the Bad. 

Let’s be realistic – how we eat and how we exercise are probably the two biggest contributors to how we look and how we measure, physically. I won’t argue that. There are also many factors outside of these two things that also contribute. I’d like to discuss one of the biggest ones: sleep! (Hint: It’s probably the most overlooked reason).

It’s not always how much we sleep, but it’s a combination of both quality and quantity that can equate to proper hormonal responses, fat loss, and all of the other great benefits of proper sleep that we can achieve.

Let’s touch base on Cortisol first. It’s such an evil word, I feel bad even typing it! Cortisol is a hormone in our body that breaks down tissues. In stressful times (including dieting), the body’s cortisol levels can be higher as the body is preparing for fight or flight status. This can cause the body to store fat as a response!

There’s a cool study in the Laboratory of Physiology in Belgium that showed daytime cortisol levels were higher in those that short themselves of sleep.

Another negative to lack of sleep is glucose control.  Let’s face it, when we can’t sleep, we get hungry and no one ever says “I can’t sleep, let’s go chow on some broccoli.” It just doesn’t happen! Usually CARBS are the culprit of these cravings. There’s a great study done in Chicago (my home!) that showed sleep deprivation can lead to increased hunger and appetite!

In all likelihood, our sneaky little bodies sense fatigue and think it’s a low energy supply, queuing internal drives to chow down on some carbs.

And my last rant here – if we don’t sleep enough, our workouts SUCK. I can quote research on this all day, but I think most of us can confirm that knowingly already.

An interesting tidbit. 

Here’s a quick fact I learned on sleep and car accidents:

A study was done on car accidents the week following daylight savings time in the Spring and Fall.

In the Spring when we lost an hour, car accidents were up 10% approximately for up to two days after the time change. 

In the Fall, when we gained an hour of sleep, car accident rates were reduced by 8-10% in the 2 days following. Personally, I think more accidents occur in the fall anyways, so this research is VERY telling.

Pretty interesting, huh?

2 Strategies for better quality of sleep. 

I am going to share a few strategies I’ve learned from books, lectures, etc. i’ve researched over the years that have made a huge impact on quality of sleep for my clients.

1. Make it a priority!

Make sure you get 7.5 hours per day. Carve it out in your calendar if you must. Here’s a cool idea: Find 10 minutes per day and add it into your sleep time. This could mean:

  • Sleeping later in the morning
  • not finishing that netflix rerun at night
  • taking a powernap

Why? Remember that tidbit about the car accidents? Now you’ve just added an extra hour per week to your sleep. That can really have a positive effect on how you sleep.

2. Protect your fort of sleeping. 

Design your own fort of sleeping. Get rid of your i-this and i-that. Research says you’ll fall asleep faster. 

Let’s start here. Try these two strategies and over a 4-6 week period jot some notes down on energy levels, weight, and overall mood. I’m willing to bet you’ll feel much better if you look these things over.

The COOLEST breathing trick you’ll ever learn.

I’m back!

HARRIS

So today’s post is going to demonstrate a really awesome breathing technique developed by an awesome guy, Dr. Andrew Weil. I’m going to get a little scienc-ey for a bit then discuss why this is so cool.

Whether it’s financial woes, health issues, or just loneliness and busy traffic, people are under more low-level, chronic stress than at any other time in history. Forty-three percent of all adults suffer adverse health effects from stress and the CDC estimates that up to 90% of all doctor’s office visits are for stress-related ailments and complaints.

Americans are so stressed out that the Occupational Safety and Health Administration (OSHA) declared stress a hazard of the workplace that costs American industry more than $300 billion annually.

Everywhere we turn in modern society, there are people and things that keep us feeling insecure and on alert. Stress can play a part in problems like headaches, high blood pressure, heart problems, diabetes, skin conditions, asthma, arthritis, depression, and anxiety.

When our adrenal glands put out more and more adrenaline and cortisol in response to our busy lives and perceived stress, and we don’t take ample time to rest, heal and recover fully, our bodies and minds become accustomed to living in a constant state of fight-or flight and start to malfunction.

There is nothing more disconcerting than feeling a heavy sense of impending doom—trembling, heart racing, light-headed, overwhelmed, scared—even though your eyes and your logic tell you there is absolutely nothing to fear. 

That anxiety you feel, that panic that is starting to take you over? It’s chemical. It’s not real; it’s not reflective of true circumstances going on right in front of you in the present moment.

If it was, you’d call it fear, not anxiety.

But it sure feels real. After all, your body is having a very real fight-or-flight reaction. You wouldn’t be trembling, sweaty-palmed and freaked out for no real reason, would you?

Well the reason you are anxious is real, but it’s not why you think. The reason for your anxiety and panic is simply that you have a stress response system that has run awol.

NERVOUS SYSTEM 101

he central nervous system is made up of the brain, the spinal cord and millions of individual nerve cells called neurons, which serve as the body’s wiring. Nerve signals are transmitted as electrical impulses through the length of a neuron. When a nerve impulse reaches the end of the neuron it jumps over to the next neuron using chemical messengers called neurotransmitters.

At the end of each neuron there are tiny sacs filled with neurotransmitters. When a nerve impulse reaches the end of the neuron, it triggers these sacs to dump their neurotransmitters into the gaps that separate one nerve cell from another. These gaps are called synapses, and the neurotransmitters float across the synapse. When they reach the neighboring neuron, the neurotransmitters lock into specialized receptor sites. When enough neurotransmitters attach to the receptors, the neuron “fires,” sending an electrical impulse down its length.

Glutamate and GABA are the most abundant neurotransmitters in the central nervous system. GABA is short for gamma amino butyric acid, and is an inhibitory neurotransmitter that is essential for the proper function of your brain and the central nervous system. GABA has the effect of reducing excessive brain activity and promoting a state of calm. While glutamate is an excitatory neurotransmitter, and encourages neurons to “fire” and send a nerve impulse, GABA does the opposite, and tells the adjoining cells not to “fire,” not to send an impulse.

Without enough GABA to balance glutamate, nerve cells fire too often and too easily. Anxiety disorders such as panic attacks, seizure disorders, and numerous other conditions including addiction, headaches, depression, Parkinson’s syndrome, and cognitive impairment are all related to low GABA activity.

GABA hinders the transmission of nerve impulses from one neuron to another. To help understand this effect, think about the last time you had some caffeine. Caffeine is a natural drug that inhibits GABA from locking into the neuron receptors. The less GABA, the more nerve transmissions occur. Think about what drinking too much coffee feels like: that is the sensation of too much glutamate in your system, without enough GABA.

This is where the 4 7 8 breathing technique comes in. 

The slow breathing rate and the increase in blood oxygen that 4 7 8 breathing creates signals the brain to release GABA! GABA, in turn, inhibits the release of cortisol and adrenaline, allowing your body-mind to finally slow down, rest, digest and repair itself.

You can use 4-7-8 breathing whenever you need to create an immediate release of GABA that will help bring your nervous system back to baseline, and make you feel calmer, more relaxed and better able to meet the challenges that life offers you.

4-7-8! 4-7-8!

The technique is called 4-7-8 Breathing, and it has four easy steps:

  1. Breathe in through your nose for a count of 4.
  2. Hold your breath for a count of 7.
  3. Release your breath from your mouth with a whooshing sound for a count of 8.
  4. Without a break, breathe in again for a count of 4, repeating the entire technique 3-4 times in a row, then resume normal breathing and activity.

If you use a second hand on a watch to count your breaths, the whole exercise will take just 57 seconds! But it doesn’t really matter if each count lasts an actual second; it only matters that you count evenly so the ratio of 4-7-8 is maintained.

You may find yourself feeling mildly light-headed after doing this. That’s actually a sign it is working, and it will quickly pass. Feel free to do this as often as you want, but you may need to get used to it first.

Many people find that this breathing technique immediately ends an anxiety or panic attack.

Why It Works

The 4 7 8 breathing technique works because when you are stressed out, your breathing becomes very shallow. People who experience long-term, chronic stress are often chronically under-breathing and are in a constant state of mild hypoxia, or oxygen deprivation. Additionally, under-breathing can lead to a build up of excess carbon dioxide in your tissues, which contributes to oxidative stress, inflammation and acidification in your body—the foundations for disease.

It’s hard to think clearly (much less be healthy) if you’re not getting enough oxygen. And when you are totally freaking out with anxiety or a panic attack, it’s common to breathe very shallowly, hyperventilate, or even unconsciously hold your breath—which affects your thinking and your health even more!

But by drawing out your inhale over a count of 4, you are making yourself slowly and consciously take in more oxygen. Then by holding your breath for a count of 7, you allow as much of that oxygen to saturate into your bloodstream as possible, cleansing and energizing all your cells, tissues and organs. Finally, by exhaling for a count of 8, you make sure you have expelled as much carbon dioxide from your lungs as possible.

The 4 7 8 breathing technique basically takes the shallow, oxygen poor breathing you normally do when you are stressed out, and turns it upside down. This has some profound effects on your body and your mind.

Just how important is posture?

So I want to share a few very valuable insights on posture – It’s something we all rolled our eyes at when we were younger, but now it’s catching up to us, in a very VERY negative way.

Check this out, for instance:

  • 65% of back pain is posture related
  • 53% of neck pain is posture related.

This is QUITE alarming.

Let’s think of some of the causes: I didn’t have a cell phone until I was 18 years old. When I had one I barely used it. Now, children are glued to their iphones at the age of 10, sometimes even younger. And they’re probably not doing soft tissue work or mobility work or even switching hands when they talk.

This can lead to neck pain, referred all the way down to back pain as they get older and such. I have had more people with pain in the last 5 years than people without, unfortunately.

I would like to bring light to some of the effects that it has, as well as an identifiable solution to one of the more common problems:

Back Pain: You should be sitting at 135 degrees if you suffer from back pain. Read below to see the research.

135 degree

Using “positional” MRI techniques researchers studied the sitting positions of 22 healthy volunteers with no history of back pain. The MRI machine allowed freedom of motion, such as sitting or standing, during imaging. Conventional MRI machines require the patient to lie flat and may mask some causes of back pain.


Researchers used the MRI to examine spinal positioning while the participants assumed three different sitting positions: slouching forward (such as hunched over a desk or video game console), an upright 90-degree sitting position, and a relaxed position with the back reclined backward about 135 degrees while the feet were still on the floor.


Overall, researchers concluded that the 135-degree reclining position put the least stress on the spine and may reduce the risk of back pain. They recommend that people who sit for long periods of time correct their sitting posture and find a chair that allows them to recline.

When I was preparing my research for the SAP Field Kick Off Meeting, I found some more alarming research insights into posture and just the effects it has on people:

A study from researchers at Columbia and Harvard showed that body language symbolizing power can actually affect our decision-making subconsciously. The researchers measured the appetite for risk of participants in either expansive, powerful poses or constricted poses (occupying minimal space, keeping limbs close to the body). Those in the powerful poses not only felt more powerful and in control, but were 45% more likely to take a risky bet.

Plus, the study used saliva samples to prove that expansive postures actually altered the participants’ hormone levels—decreasing cortisol (C) and increasing testosterone (T):

This neuroendocrine profile of High T and Low C has been consistently linked to such outcomes as disease resistance and leadership abilities.

So clearly, our posture has more to do with our minds than we might have thought. And, in fact, it seems like our bodies come first: When we alter our posture and body language, it subconsciously influences our thinking and decision-making.

So moral of the story: PAY ATTENTION TO HOW YOU SIT!
