Is this you…

Like a trusty guard dog, your smart phone probably rests right next to you (or even under your pillow) every night when you go to sleep. You’re able to answer calls, texts and emails at a moment’s notice – even during the wee hours of the night.  And isn’t that the best part about technology? Always being connected and never truly shutting down or logging off?  Not so fast. You probably don’t even realize how your smart phone habits are affecting your sleep.

1. It keeps your mind psychologically engaged

Smart phones were designed to make us more productive and our lives easier. They’re designed to entertain us and provide information. But when it’s time to turn off the lights and go to sleep, the last thing our brain needs is more information and more entertainment. (And that seems fair enough – we give our brains enough to think about during the day!)

The smart phone era has forced us to feel like we can never really log off, even when we’re sleeping.   Your mind can stay active and engaged long after you’ve scrolled through Instagram or responded to a few work emails. Going to bed and falling asleep should be a peaceful, happy and relaxing experience. Engaging with your phone too close to bedtime can negatively impact those feelings.

2. The blue light from the screen suppresses melatonin

Blue light from screens of laptops, tablets and smartphones supresses melatonin.  Melatonin is a hormone responsible for controlling your sleep-wake cycle. So when your body runs low on it, you can experience insomnia, tiredness during the day and irritability.

3. Alerts delay REM sleep

Knowing your smartphone is at hand can mean you are aware of new email alerts or social media alerts.  These alerts or simply waiting for these alerts can delay REM sleep.

So if you want to improve the quality of your sleep simply have 1 hour technology free before bed.

  • How to protect your eyesight as you get older

    I have been wearing glasses since I was a teenager, so I am always interested in how to protect my eyesight.  One of the most common cuases of failing eyesight as we get older is age related macular degeneration (AMD). Scientists tracked the diets and eye health of over 2,000 people who were at least 49 years old at the start of the study.  The people's eye sight and diet were then tracked over the next 15 years.  The researchers discovered that those eating between 100 - 142mg of vegatable nitrates were less likely to have the early signs of AMD.  Currently once AMD starts medicine has no answers and it can in some cases cause blindness. This means prevention of AMD is very important. Vegatable nitrates found in leafy green vegatables and beets reduces the risk of developing AMD by 35%.  100g of spinach contains 20mg of nitrate.  One serving of spinach is 30g, so you would need ot eat 3 servings.

  • What can help period pain – Part 3?

    While taking nutritional supplements suits some women, I know others don’t like taking tablets.  So here are a couple of other ideas to assist you with your period pain. There is scientific evidence that from a trail of women who suffer from period pain that certain yoga poses e.g. cobra, cat and fish reduce both the intensity and duration of period pain.  The cobra pose is where you lie on your front, with your hand underneath your shoulders and gently push yourself up bending your back as you come up.  The cat pose is when you are on all fours and then round your spine like a cat.  The fish pose is when you lie on your back, keep your pelvis and head on the floor and an arch your spine towards the ceiling. As an aromatherapist there are a variety of essential oils that you can use to help reduce the severity of period pain.  Aromatherapists split period pain into two categories:

    • Congestive dysmenorrhoea – where the pain starts a few days before the period and can cover the whole abdominal area.
    • Spasmodic dysmenorrhoea which comes in spams of pain in the pelvis and/or lower back.
    For congestive pain: 10 drops of roman chamomile + 5 drops of clay sage and 15 drops of red thyme in 30 ml of a base massage oil. For spasmodic pain: 5 drops of lavender, 10 drops of peppermint, 10 drops of nutmeg and 5 drops of cypress in 30 ml of a base massage oil. In both cases you massage the whole abdomen and lower back daily throughout your period. References: Yoga poses >> https://www.ncbi.nlm.nih.gov/pubmed/21514190

  • How do you look after your bones if you are dairy free?

    We all know our bones need calcium and normally we get this from diary.  But more and more people are going dairy free for a variety of reasons including following specific diets. The UK's National Osteoporosis Society surveyed 2,000 adults found that one in five of those aged between 18 - 25 had cut diary from their diets.  As a result they could be putting their bone health at risk and could end up with osteoporosis in older age, the society has warned. But diary isn't necessary for achieving bone health, says Viva the animal rights group.  Instead,

    • weight bearing exercise such as walking
    • climbing stairs
    • dancing
    is the best way followed by these foods:
    • dark green leafy vegatables
      • broccoli
      • kale
      • spring greens
      • cabbage
      • pak choi
    • dried fruits
    • nuts
    • seeds

    It is also important to remember that vitamin D, the sunshine vitamin, helps us abosb calcium better.
