What are your stress signs?

Everyone experiences stress differently and it can be helpful to learn what your personal signs are so that you can better look after yourself.

Your stress signs are how your body talks to itself, letting you know that it needs some attention and support. When you learn what your stress signs are, the trick is to acknowledge them and give your mental health the nourishment it needs.

So what do stress signs look like? There’s a wide range of warning signs, some obvious and others a little more subtle. They can be physical, emotional or mental.

Read through the list below, and see if you can spot anything familiar:


Physical signs:


    • Difficulty falling asleep
    • Light and disturbed sleep and waking feeling unrested
    • Waking at 3am and not being able to go back to sleep
    • Low energy, feeling exhausted
    • Recurring headaches or migraines
    • Muscle tension – particularly in the neck and shoulders
    • Increased PMS
    • Facial muscle twitches
    • Constant bouncing of your leg when stationary – when feeling bored or anxious
    • Getting sick all the time – low immunity
    • Loss of appetite or comfort eating
    • Disorders may worsen or develop


Emotional/Mental signs:


    • Getting grumpy or angry
    • Over-reacting, and feeling emotional and sensitive around others
    • Feeling on edge, nervous or anxious during the day, having panic attacks

Were any of those a little too relatable? Read on to learn more about why they happen, and what you can do.


What is the stress hormone?


Adrenal glands sit on top of your kidneys, and they release a range of different hormones, one of which is cortisol. This is otherwise known as the ‘stress hormone’. Stress hormones are produced for a variety of physical and mental reasons. For example, if you are feeling anxious or stressed you will produce more cortisol.

When experiencing heighten levels of stress over a long period of time (ie constantly releasing the stress hormone cortisol), your adrenals can become fatigued. This can cause them to start releasing stress hormones at the wrong time, which can disrupt your ability to fall or stay asleep.


In fact: one of the most obvious signs that stress is affecting your health, is a change in the quality of your sleep.


Do you dream?


Dreams usually develop from your daily activities, thoughts, and feelings. They can tell a funny story or sometimes, a more serious one. What you experience during your day can heavily impact your dreaming at night.

If you have been stressed, this can result in stress dreaming which is when our dreams create a feeling of stress or intense anxiety. It can also lead to nightmares or waking up suddenly in the middle of the night sweating and feeling panicked. For example - you might be nervous about a job interview the following day, and that night you stress dream about getting to an important destination at the wrong time.

Stress dreams reflect our emotions and are a red flag that we might be experiencing stress during the day.


Fun fact: You may or may not remember your dreams, but your brain will always dream, whether you remember them or not!


Foods for Stress and Sleep


Anti-sleep foods:

The below stimulating foods and drinks can increase your cortisol (stress hormone) levels, making it harder for you to get to sleep:


  • Caffeine - Coffee, Green or Black Tea, Energy Drinks
  • Foods high in sugar - because your body uses sugar to fuel the body
  • Salty foods - as these can increase your heart rate making it harder to relax.


Combining these stimulants with increased stress levels can cause overstimulation, which understandably can also make your sleep worse.

A word on alcohol: We know at the end of the day you may enjoy a beer or a glass of wine to help ‘wind down’. But if you are someone really struggling with their sleep, this may actually be making your situation worse, Alcohol can lead to a restless sleep later in the night which doesn’t help with your cortisol balance, and the result – and even more restless sleep!


Sleep supporting foods:


But, good news - there are foods that can help us sleep! Magnesium rich foods can be helpful because it plays a role in muscle and nerve function. It also regulates your blood pressure and blood sugar. It may help regulate neurotransmitters that are related to sleep.

Studies have shown that eating foods high in magnesium can support:


    • Falling asleep
    • Reduced muscle twitching, especially restless legs
    • Sounder, more restful sleeps


So what foods are high in magnesium? Here are some healthy foods we recommend:


    • Pumpkin seeds, almonds and peanuts (unroasted and unsalted)
    • Green leafy veges
    • Avocado
    • Legumes such as peas, beans and tofu
    • Bananas
