Crankiness, or irritability, refers to a state of heightened sensitivity and annoyance. Individuals experiencing crankiness may find themselves easily frustrated by minor inconveniences or disruptions. This emotional response can be triggered by various factors, including stress, lack of sleep, or hormonal changes. Crankiness can affect daily interactions and overall well-being. It may lead to conflicts in relationships and decreased productivity. Understanding the underlying causes, such as stress management techniques or healthy sleep habits, can help individuals cope with and reduce feelings of irritability.
