People often describe being stressed when they are dealing with demanding workloads, family responsibilities, financial concerns, relationship difficulties, major life changes or uncertainty about the future. Short periods of stress can sometimes help us respond to challenges. Problems are more likely to arise when pressure continues without sufficient opportunity for recovery.
Signs that stress may be becoming difficult to manage can include feeling constantly overwhelmed, difficulty switching off, irritability, poor concentration, sleep problems, fatigue, reduced motivation, headaches or muscle tension, feeling emotionally detached, and losing enjoyment in previously valued activities.
Burnout can develop gradually. Someone may initially attempt to manage increasing demands by working longer hours or sacrificing rest and personal activities. Recognising the early signs of emotional overload can create an opportunity to make changes before difficulties become more severe.
