fight or flight: our natural response to danger
Fight or flight describes the body's automatic response to danger. It's thought that this evolved hundreds of thousands of years ago as a way to help us react to life-threatening situations. Because it's an automatic response, it's often triggered without us realising it - or being able to prevent it.
In the presence of danger, our eyes and/or ears send information to the amygdala, the area of the brain which is responsible for processing our emotions. The amygdala sends a distress signal to an area at the base of the brain called the hypothalamus, which communicates with the body via the nervous system.
The hypothalamus activates the sympathetic nervous system. This sends signals to the adrenal glands, which then produce hormones including adrenaline, norepinephrine, and cortisol into the bloodstream. As these hormones circulate through the body, they trigger a range of physical changes.
If the brain perceives the threat as ongoing, the hypothalamus releases more hormones. These act on the adrenal glands, making them release more cortisol and leaving the body in a continued state of alert.
When the brain believes the threat is over, it reduces cortisol levels. The hypothalamus also activates the parasympathetic nervous system, which dampens the stress response.
long-term effects of chronic stress
Sometimes, a stress response can be useful. It can boost our awareness in stressful situations and help us cope with emergencies.
But if it happens too often, or for too long, the content release of stress hormones can lead to physical health problems including:
- stomach or digestive problems like diarrhoea, constipation, and nausea
- a weakened immune system, causing regular colds and infections
- exhaustion or sleeping problems
- heart disease
Long-term stress can also lead to emotional and mental health symptoms, such as:
- anxiety or irritability
- depression
- panic attacks
- sadness
It’s incredibly important to listen to our bodies, especially if we’re experiencing any of the symptoms mentioned above. Stress, and the symptoms of stress, must be taken seriously. If they’re not, as we’ve seen, it can cause real issues for our mental and physical health.
“My husband said he hadn't realised how far he'd strayed from his values and where he wants to be. We were able to discuss the need for peace and tranquillity and talk about some goals together.”
seven ways to prevent stress
1. move more
Exercising reduces the build up of stress hormones in our body. Even a short walk outdoors can boost your mood. It can also give you an opportunity to clear your mind without any distractions.
2. eat well
While we shouldn’t deprive ourselves of treats, or become obsessive about our diets, eating a balanced diet will naturally boost your mood and give you more energy.
3. sleep well
Getting a good night’s sleep helps you keep things in perspective. If you’re struggling to sleep well, Sleepstation can support you.
4. stay positive
It’s natural for us to only focus on what we haven’t achieved each day. But it’s important to sit back and think about what you have achieved. This will help to improve your mindset over time.
5. set realistic goals for each day, week, and month
Doing so will narrow your view and help you feel more in control of short and long-term tasks.
6. set boundaries
Saying ‘no’ to colleagues, family members, and loved ones can be terrifying. Which is why we usually say yes, even if it’s likely to increase our stress levels. But saying ‘no’ promotes healthy boundaries with the people around you. It also opens up a dialogue which allows you to talk through what your current focus is.
7. make time for relaxation
Dedicating a small portion of your day to relaxing not only gives you something to look forward to, but also gives you that all-important opportunity to switch off.
Self-care is often sniffed at but has never been more important. Simple things like treating yourself to a long bath after a tough day helps you compartmentalise the negative emotions you may be experiencing, relax tension you’re carrying in your muscles, and calm your mind.
