Stress at work, anxiety, depression, PTSD, even low self-esteem - all can have an impact on our sleep, and sometimes even our dreams play their part in expressing something of the problems we face in our daily lives.
There was recently a hearing in the US that contributed to an ongoing broader debate on the impact that social media and other online communities are having on people individually and society at large, specifically how these platforms may be deliberately trying to make people addicted. Is this possible? And what does it say about the nature of addiction?
This is really worth listening to: 'Unhappy Child, Unhappy Adult'. A Radio 4 programme on the effect of adverse childhood experiences on adult mental health.
We already know that unhappy experiences in childhood are more likely to lead to mental health issues in later life.
What's becoming clear, however, is that chronic stress and anxiety during this time can trigger dramatic changes in the body which contribute to our risk of developing diseases like diabetes, heart disease, cancer and stroke. Chronic stress in childhood is also associated with a shortened life span.
Health-harming behaviours which contribute to disease risk, like smoking, drinking alcohol and drug use, are more common among those who have endured traumatic experiences in childhood.
But scientists are now revealing that these stressful childhood experiences have a direct impact on our physical health, through their impact on the developing brain and the immune system.
The question now is how to use this knowledge to improve the nation's health. Should health professionals routinely ask patients about traumatic events in their childhoods? And if so, who should broach the subject, where and when?
Geoff Watts visits a GP practice which is about to trial this novel idea, and looks at the growing body of evidence revealing how adverse childhood experiences contribute to poor health and shorter lives.

There is no denying that the pursuit of love in the 21st century is littered with digital landmines. Psychologist and psychotherapist Karina Melvin works with many clients who regularly use dating apps and come to her Sandymount clinic seeking help and advice.
"In my experience it absolutely depends on who is using these apps and how they are used. Dating apps open up the possibility to make a genuine connection with someone. The whole point of these apps is to create an opportunity to meet people in person and this is what many users do.
"There are numerous sites, apps and forums on the internet where the aim is to develop and maintain a 'virtual' relationship, but with dating apps the interest is precisely because you can actually meet the people you are talking to."
