The Effects of Sleep Deprivation on Your Body - Tips for a Better Nights Sleep

Information supplied by Healthline and the Southern Cross Team

If you’ve ever spent a night tossing and turning, you already know how you’ll feel the next day — tired, cranky, and out of sorts. But missing out on the recommended 7 to 9 hours of shut-eye nightly does more than make you feel groggy and grumpy.

The long-term effects of sleep deprivation are real.

It drains your mental abilities and puts your physical health at real risk. Science has linked poor slumber with a number of health problems, from weight gain to a weakened immune system.

Causes of sleep deprivation

In a nutshell, sleep deprivation is caused by consistent lack of sleep or reduced quality of sleep. Getting less than 7 hours of sleep on a regular basis can eventually lead to health consequences that affect your entire body. This may also be caused by an underlying sleep disorder.

Your body needs sleep, just as it needs air and food to function at its best. During sleep, your body heals itself and restores its chemical balance. Your brain forges new thought connections and helps memory retention.

Without enough sleep, your brain and body systems won’t function normally. It can also dramatically lower your quality of life.

A review of studies in 2010Trusted Source found that sleeping too little at night increases the risk of early death.

Noticeable signs of sleep deprivation include:

Stimulants, such as caffeine, aren’t enough to override your body’s profound need for sleep. In fact, these can make sleep deprivation worse by making it harder to fall asleep at night.

This, in turn, may lead to a cycle of nighttime insomnia followed by daytime caffeine consumption to combat the tiredness caused by the lost hours of shut-eye.

Behind the scenes, chronic sleep deprivation can interfere with your body’s internal systems and cause more than just the initial signs and symptoms listed above.

Sleep issues

If you’re not sleeping enough, or the quality of sleep you’re getting is poor, it can lead to some pretty serious issues. For a start, feeling tired slows down your reaction times, increasing your risk of accidents at home, work, out and about or behind the wheel.

Lots of research also strongly suggests that prolonged poor sleep can lead to life-threatening conditions such as depression, heart disease, high blood pressure, diabetes and stroke, to name but a few.1

The good news is, however, that there are plenty of things you can do to help improve your sleep and prevent things ever going this far.

Here are some of our top tips to help you sleep better at night, and add some pep to your day:

1) Get a routine

Our bodies crave consistency, so try to get regular with your sleeping habits. Go to bed and get up at around the same time each day, including weekends if you can – even if you haven’t slept well the night before. Your internal body clock will thank you for it. And remember, having a consistent routine also includes…

2) Wind down before bedtime

How you prepare for sleep can be just as important. Take time to wind down with some gentle activity – reading, taking a bath, some simple breathing exercises, perhaps, or listening to music or a podcast. Drinking a warm glass of milk can also help as it contains tryptophan, a natural sleep inducer.2 Whatever it takes to calm your mind ready for some relaxing shut eye.

3) Create a restful environment

In other words, get your bedroom all set up for sleep mode. Make sure it’s dark, quiet and cool (between 15°-20°C is ideal), and ensure your sheets, duvet and pillows are clean and comfortable. Also try to keep your bedroom a haven for sleep and intimacy only – a welcoming place you look forward to visiting.

4) Manage your worries

Stressing about what’s happened today or what you have on tomorrow? Give it a rest, literally. Problems can often seem more daunting at night, so try not to think about them. Jot them down then let them go, they’ll wait until morning when you’re not so tired. And they may not be as bad as you feared in the light of day - especially after a good night’s sleep.

5) Stay active during the day

It’s a fact that regular exercise helps you sleep better, so why not start early? A brisk morning walk is a great way to feel refreshed and set up your day, but a lunchtime stroll or gym visit could equally do the trick. Just don’t over-exert yourself closer to bedtime (within three hours, say), as it could wake your body up and actually impinge upon your sleep quality.

6) Limit your daily naps

Love your little Nana naps? Many people do, especially as we get older. We’re not saying don’t do it, just keep them short – 20 or 30 minutes is perfect – before you settle into a deeper sleep and wake up all groggy. Alternatively, when you feel tired in the afternoon, try doing the opposite – take a short walk, drink some water, or have a chat with a mate. It might help you overcome those forty winks.

7) Ditch the devices

We all love our phones, tablets, computers and TVs, but try to avoid exposure to them within the last hour before bedtime. The blue light emitted by their screens can trick your body into thinking it’s still daytime, which can mean your sleep pattern is knocked out in turn.

8) Cut down on stimulants

Last but by no means least, we come to stimulants - the triumvirate of alcohol, nicotine & caffeine. Again, try to avoid them too close to bedtime, especially alcohol. It may help you feel sleepy and drop off initially, but your quality of sleep may suffer.3


We hope some of these tips may help. Please remember, sleep is important, so if your restless nights or insomnia last for a month or more, be sure to visit your doctor or health professional for advice as soon as possible. Don’t just sleep on it.
