WHAT’S IMPACTING YOUR SLEEP AND A FREE YOGA NIDRA SESSION

March 13, 2022 3 Comments

How are you sleeping? Annabel and I both feel anxiety about the conflict in Ukraine is really impacting our sleep. I’ve been having weirdly vivid dreams too. Quality sleep is a key pillar of our Age-Well Project so I’ve rounded up the latest research on the subject to share with you. I’ve included some practical take out – and read on  to book your ticket for our free yoga nidra event aimed at getting better sleep.

GUT HEALTH AND SLEEP

We know that gut health is important for a healthy brain, but new research from Japan suggests that the health of our gut microbiota also has a direct impact on our sleep patterns. The community of bacteria, fungi and viruses in our gut help produce serotonin and dopamine, feelgood neurotransmitters involved in the sleep-wake cycle.

The study looked at mice, not humans, but is still worth reviewing. The mice were given water containing broad spectrum antibiotics to deplete their gut microbiota. The result? They stopped producing serotonin and suffered disrupted sleep-wake cycles: staying awake when they should have been asleep and being sleepy at times when they were usually active.

TOP TIP: we’ve written about gut health here and here but our microbiota need FOOD and FRIENDS. Give them prebiotic foods to ferment for their own nourishment, for example:

  • Lentils, chickpeas and beans
  • Oats
  • Bananas
  • Jerusalem artichokes
  • cold potatoes and cold cooked rice
  • Asparagus
  • Garlic
  • Leeks
  • Onions
  • Nuts

and new ‘friends’ in the form of probiotic foods like:

  • Kefir and live natural yoghurt
  • Aged cheeses like camembert and Emmental
  • Fermented soy like tempeh and natto
  • Kimchi and sauerkraut
  • Kombucha (a fermented tea)

CIRCADIAN RHYTHMS AND ALZHEIMER’S

Respecting our circadian rhythms, which govern the sleep-wake cycle – is vital for good sleep. And now new research has linked these internal ‘clocks’ to our immune system’s ability to destroy the amyloid beta plaques associated with Alzheimer’s. Our circadian rhythms are a natural system designed to anticipate day/night and send in the right ‘team’ so the body gets what it needs – be that sleep, digestion or the immune function which clears toxins from our brain – when appropriate. If our cycle is out of whack, it doesn’t know which team to send in when.

“Circadian regulation of immune cells plays a role in the intricate relationship between the circadian clock and Alzheimer’s disease,” explained the lead researcher on the project. “This tells us a healthy sleep pattern might be important to alleviate some of the symptoms in Alzheimer’s disease.’

TOP TIP: We can anchor our clocks with regular bedtimes and rising times: even if we don’t sleep, our bodies need to know when they’re supposed to sleep. It helps to build a sleep ramp: the practices we go through before bed each day to prepare us for sleep. That could be dimming the lights, a warm bath, reading a book or listening to music.

INSOMNIA AND SUGAR

I recently came across a report into insomnia among women over 50. It’s a couple of years old but I wanted to share it as I know so many of you have struggled with this debilitating condition at times. The researchers reviewed the data of over 50,000 women and found that a diet high in refined carbs – particularly sugar – was linked to sleep issues.

It was difficult for the research team to extrapolate whether the women tracked in the research had consumed more refined carbs, especially sugary foods, because they were suffering insomnia, or vice versa. I think we all know the cravings for sweet things after a bad night’s sleep….

But they also pointed out that eating sugary foods results in raised insulin levels, followed by a dramatic drop in blood sugar levels. This in turn leads to the release of the hormones adrenalin and cortisol (the stress hormone), which interfere with sleep.

TOP TIP – avoid sugary snacks in the evenings! The women on the study who ate more fruit and vegetables were less likely to have insomnia.

YOGA NIDRA FOR SLEEP: A FREE ZOOM SESSION WITH KANAN THAKERAR

Our lovely friend, the yoga nidra teacher Kanan Thakerar, is running a free online session for followers of The Age-Well Project on Tuesday 29th March at 7pm BST. I do so hope you can join us there.

Yoga nidra is essentially the lying down bit of a yoga practice where you consciously relax your mind. It uses guided visualisation, allowing the body to slumber whilst the mind stays awake. The practice engages the left and right side of the brain which aids creativity, reduces stress and builds neuroplasticity. It’s the most relaxing thing I’ve ever done!  Kanan will focus this one-hour session on helping us get a good night’s sleep. She also runs a sleep clinic and will be sharing her top tips. I’ll be there in my pyjamas….

Free tickets are available from Eventbrite and you can book them here

The event will be recorded if you can’t make it live, and the link sent out by Kanan’s team afterwards.

    I thought it important to mention that cold cooked rice,, if it is not chilled quickly and stored in a fridge, is a common cause of food poisoning. The NHS website has more information about this.

      Yes absolutely Kate. Thank you so much for mentioning this. And it should be reheated very thoroughly and only once

    Yes indeed, just the once and then bin the leftovers. I hope this doesn’t put people off. I have eaten cold rice in salads for years without any problem. Great with a French dressing.

Look, we know not many people have round-the-clock Look, we know not many people have round-the-clock access to a sauna. But Susan found one in a hotel she was staying at recently, there’s one in our local gym and Annabel found plenty on her summer holiday in Finland. 

A growing number of studies attest to the longevity-enhancing benefits of routine forays into a sauna. Much of the research has been instigated in Finland where sauna (pronounced to rhyme with downer) has existed forever.

So how does sauna help us age well? The extreme heat activates heat shock proteins which researchers think can maintain the healthy functioning of our cells.  As we get older, the proteins in some of our cells start to misfold and collapse. They then clump together forming plaques, including the plaques thought to cause Alzheimer’s and dementia.

Heat shock proteins – triggered by a sauna stint and possibly by hot baths – appear to prevent the misfolding and collapsing of cellular proteins, as well as clearing out those that have already misfolded. Which is to say they keep our cells in good shape.

If you’re new here, we’re Susan and Annabel, long-time friends turned longevity writers. We started blogging about our quest to age well almost a decade ago (!) - you can find the blog at agewellproject.com or via the link in our bio. 

As working mums, we started looking for simple, science-backed ways to make the best of the second halves of our lives. We wanted to improve our own health and reduce our risk of the chronic conditions of ageing. When we started writing, Susan was caring for her mum, who had dementia, and Annabel has also faced challenges with her family’s health. 

Along the way, the blog became a best-selling book, The Age-Well Project, and further books have followed. You can find out more about us individually @annabelabbs and @susansaundershealth 

The blog is packed with posts on the latest research into the science of longevity, and how we make sense of it in our own lives. And there’s also loads of lovely age-well recipes - all approved by our families!
