Wellness: How journaling can boost your immune system and mental health

Journaling is becoming increasingly popular in wellness circles. Keeping personal diaries used to be seen as a practice for teenagers and career writers, but journaling has become a recognised therapeutic, accessible tool for people of all walks of life. It's often included in lists of self-help mindfulness practices, along with cold showers and meditation.

It's used as a form of cognitive behavioural therapy to increase feelings of gratitude and happiness, and banish feelings of depression and anxiety.

However, not only is journaling great for our mental health: it's also great for our physical health too. A report from the American Psychological Association (APA) examined several pieces of research into the practice's influence on our immune system, helping us to fight off diseases, and even recover from physical injury.

Research from the University of Texas at Austin found writing to record and understand emotion could boost immune functioning in people with underlying health conditions, like asthma, arthritis or even HIV. 

Emotional stress can limit the effectiveness of our immune system due to the secretion of the "stress hormone" known as cortisol. It's thought journaling, with its stress-busting qualities, limits the secretion of this hormone and allows the immune system to do its job effectively. 

How to start journaling

There's lots of ways to start journaling, but the report from the APA says venting emotions alone--whether through writing or talking--is not enough to relieve stress. To tap writing's healing power, people must use it to better understand and learn from their emotions. 

Researchers from the University of Auckland, New Zealand, asked patients to write about either negative life experiences or their daily schedules, resulting in a short-term increase in immune system function and a decrease in stress. 

Try following this example: at the start of the day, first plot out your daily schedule. Second, write down  a list of negative thoughts, anything you're ruminating over at the moment, so you can look at it in black and white. Finally, list three things you're grateful for. 

This ought to be a good start. Maintaining a regular journaling practice benefits both your mental and physical health, and (best of all) all you need to get started is a pen and a notebook.
