What happens when you don’t get enough sleep?

by Danielle Minnebo
What happens when you don’t get enough sleep?

Have you ever wondered what happens to your body when you don’t get enough sleep? People often underestimate the importance of getting a good night sleep. Wellbeing is not only impacted by what we put in our mouths and how we move, but it’s also influenced by how much sleep we get each night and the quality of this sleep.

What actually happens when you don’t get enough sleep?

  • Increased appetite and weight gain: Studies have shown consistently that getting 5 hours or less of sleep a night results in weight gain. Studies have also shown that people with sleep problems, such as having trouble falling asleep, waking frequently during the night and having trouble staying asleep, are also more susceptible to gaining weight.
  • Inflammation: Chronic lack of sleep increases the release of inflammatory markers in the body, such as C-reactive protein, eicosanoids and prostaglandins. Elevated C-reactive protein increases our risk for cardiovascular disease, stroke and diabetes.
  • Mental focus and attention: Chronic sleep deprivation affects our psychomotor function, memory retrieval, productivity and ability to focus and pay attention.
  • Affects your blood pressure: Consistently getting less than 6 hours of sleep a night increases your blood pressure. For example one review found that women who sleep less than 5-6 hours nightly are at greater risk of developing high blood pressure.
  • Affects our immune function: Lastly, chronic sleep deprivation reduces our immune function and makes us more susceptible to infections. One study found shift workers reported more infections than day workers who received 8 hours of sleep each night.

How many hours of sleep should we be getting each night?

This can be a hard question to answer, yes ensuring a good night sleep is important, but putting a number on this can be a challenge, as individuals can be very different. As a general rule I recommend 8-9 hours of sleep each night, at a minimum 7 hours a night. It is important that you receive these hours of sleep each single night. Catching up on sleep over the weekend has shown to not negate the effects of not getting enough sleep during the week.

What can you do to get enough sleep each night?

Simply going to bed, closing our eyes and drifting of to sleep often isn’t enough to ensure we get a good night sleep or even that we’ll fall asleep. There are a number of different things you can do to make sure you have a restful night sleep and most of these things have to do with encouraging the release of melatonin, which is our sleep hormone. It ensures we fall asleep easily, stay asleep and wake feeling rested.

  • Remove your computer, laptop and TV from the bedroom. Create an environment that is purely for sleeping.
  • Switch your mobile phone to flight mode. Your mobile phone releases electromagnetic fields or EMF, which disturbs melatonin production.
    Make sure your room is completely dark and there is no light coming in from outside. Studies have shown that even the smallest amount of light can reduce the production of melatonin by the brain. Also ensure it’s a cool room as that ensures a more restful sleep.
  • Don’t use your laptop, computer or watch TV 1 hour before bed. The blue light released from these appliances reduces the production of melatonin in the brain.
  • No caffeine after lunch and certainly not just before bed. Caffeine triggers the release of cortisol, which is a stress hormone that is naturally low towards the end of the day. Cortisol interferes with melatonin production and reduces its conversion from serotonin.
  • Avoid eating just before bedtime; instead eat no later than 2 hours before bed. Ensure you have a meal that contains enough protein, good fats and carbohydrates, this will ensure your blood sugar levels remain steady throughout the night and you don’t wake early in the morning due to hunger. Try and avoid sugary foods before bed, such as chocolate, cake or ice cream. These will cause your blood sugar levels to rise dramatically and also crash dramatically. This can result in a restless night sleep and again waking early due to hunger.
  • Dim the lighting 2 hours before bed if this is possible. Due to electricity and lighting we have created eternal daylight. Our bodies are no longer able to properly listen to their evolutionary signals of the sun rising and setting, we turn on all the bright lights as soon as the sun has set. We can reduce the effects of this by dimming light towards the end of the evening and using lights that are lower to the ground, this tells our bodies that night is approaching and to prepare for sleep.

  • An oldie but a goodie! I’ve just updated this recipe to make it even better. Perfect time for Christmas as well, the raspberries make it extra festive. This is a gluten free recipe but still uses the non-negotiable ingredients when making brownies which are butter and good quality dark chocolate 🍫 😊 recipe in my profile link.
  • Today's lunch for little man, mashed potato rolled into balls, so it's easy for him to grab, zucchini and mushroom cooked in butter with a lamb cutlet. 

Swipe across for the aftermath! All of it was definitely not eaten, in fact a lot ended up with the dog, in his hair and on the floor! But it's important to continue to expose them to vegetables and the foods you don't think they'll like or eat. Even if some meals it doesn't seem like they've eaten very much. This repeated exposure helps them become familiar with the food and eventually enjoy it.
  • This post has been brewing in my mind for a while now. Who do you follow on instagram for nutrition advice and inspiration? Are you aware of the influence they can have on you? How you feel about your body and the food choices you make?

As someone who has come from a background of disordered eating, I see so many red flags when I'm on social media now. I can identify them as red flags because of the work that I have done on myself and also from my nutrition education. I worry that the average user isn't able to identify these red flags. 

As you scroll through your social media feed keep an eye out for these. Then stop and ask yourself why you're following this person and how are they making you feel about yourself.
  • First recipe back for a little while and of course it’s baby/toddler friendly 😀 It’s a really simple Zucchini & Pumpkin Slice, perfect to cut into soldiers so little hands can grab them. I can confirm that they were a hit for lunch today. Recipe link in bio 🌱 😊
  • We’re having a SPRING SALE 🌺🌷🌻 over at @foodtonourish 20% OFF until midnight Sunday, head over to our Insta page to get the coupon code 😃
  • Hi 👋 it’s been a long while between posts! I’m feeling inspired to jump back on here and share more of my cooking creations and nutrition tips. A few things have turned our life around for the better in the last year, one of them being this little bundle of joy, Jakob Leo Hewitt 🥰 wow, what an insane ride motherhood is! He’s almost 11 months and it’s only now that I feel a bit more like myself again, although forever changed that’s for sure. 

Really looking forward to sharing more of my recipes again, lots of tips around feeding little ones now that I have one of my own. And also sharing more about my journey to motherhood as it wasn’t an easy one. I learned so much in the process and have a lot to share on how you can also empower your journey to motherhood, what is in your control and what you have to surrender too. But more on that later!
