Your Sleep and Health

The Guinness Book of World Records find it acceptable for a man (Felix Baumgartner) to ascend 128,000 feet into the outer reaches of our atmosphere in a hot-air balloon wearing a spacesuit, open the door of his capsule, stand atop a ladder suspended above the planet, and then free-fall back down to earth at a top speed of 843mph (1,358kmh), passing through the sound barrier while creating a sonic boom with just his body (Walker 2017 p. 133). Yet, this same Guinness Book of World Records will no longer accept any challenge to sleep deprivation as the health risks associated with it are considered far greater.

Today, I am 63kgs lighter than I was 22 months ago. I exceeded my goal weight of 80kgs around the 12 month mark and have been weight stable at about 76-77kgs for the past 10 months. At the start of my journey, I was 138.8 kg, I was at my heaviest ever! A life of yoyo dieting since I was a teenager, banana diets, soup diets, Weight Watchers, you name it I tried it, lost a bit and put it on plus more.  The decision to have the gastric sleeve was not easy and quite scary. I thought… ‘I have tried everything, what if I fail at this as well?”. I’m a very social person and it sounds silly to say, but I put it off for about a year because I was also worried about giving up the bubbles, but looking back, that was such a small thing to give up when I have gained so much more.  

With that in mind, as we put on our dancing shoes and meet up with friends over the next few months in festive celebrations, you might want to take a minute to think about sleep.

Any less than 7 to 8 hours of sleep each night leads to malfunctioning of many parts of our brain, contributing to numerous neurological and psychiatric disorders as well as affecting every physiological system of the body.  There are direct associations to Alzheimer’s, anxiety, depression, bipolar disorder, suicide, stroke, chronic pain, cancer, diabetes, heart attacks, infertility, weight gain, obesity and immune deficiency.

In regard to weight, with just 5 to 6 hours of sleep a night (compared to 7 to 8 hours), there is a significant increase in ghrelin and a material decrease in leptin, meaning you have much more of the “I’m hungry” hormone and much less of the “I’m full” hormone.  Added to this, there is an impact on the types of food you crave with a marked increase in sweet and heavy carbohydrate loaded foods.  A lack of sleep makes you feel hungry, and eat crap.

It was through stories like the one I am sharing with you now, that changed my mind and gave me the courage to give it a go! My close friend and I made the decision to do it together and chose to go through WLSA after lots of research and information sessions with other companies. It was a great support for us both, to not only be going through this together but to have such a supportive team from WLSA to fall back on at every rough and tough time, as well as with our successes.  

If you struggle to have a good sleep each night, here are some pointers:

  • Have a sleep schedule – go to bed and wake up at the same time each day. If you struggle to go to bed at the same time, set an alarm for your bed time.
  • Exercise can help – try for a minimum of 30 minutes on each day but not later than 2 to 3 hours before bed.
  • Avoid/reduce caffeine –obviously stimulants can make it difficult to fall asleep. Nicotine is also a stimulant often causing smokers to sleep only lightly and can wake them up early in the morning due to nicotine withdrawal.
  • Alcohol can help you relax however robs you of REM sleep, keeping you in the lighter stages of sleep and can wake you up in the middle of the night when the effects of alcohol have worn off.
  • Common medications can disrupt sleep –including some heart, blood pressure, asthma medications as well as herbal remedies for colds and allergies – chat to your GP about your meds if this concerns you.
  • Have a relaxing ritual before bed to unwind – read a book, listen to music etc.
  • Have a dark, cool & gadget–free bedroom.
  • Natural sunlight regulates daily sleep patterns – try to get outside for 30 minutes each day.

If you like to read, Why We Sleep by Matthew Walker PhD – professor of Neuroscience and Psychology at UC Berkeley, should be next on your list. It is an evidence-based, fascinating, albeit quite confronting read about sleep and how important it is for our health.
