Did you know that 6.9 percent of adults in the US have suffered from depression in the past year? That’s 16 million people, many of whom have grappled with symptoms including fatigue, lack of appetite and intense sadness.

The reasons for this explosion in mental health problems are varied, but many doctors put it down to our increasingly stressful modern lifestyles, characterized by lack of sunlight, poor diets and non-stop jobs. No wonder then that a few simple changes to our lifestyles can help lift the cloud of depression for good.
