Multitasking is often viewed as a productivity hack, but research suggests that it can have negative impacts on mental health, happiness, and the ability to learn new things. The true cost of multitasking lies in its effects on focus, attention, and overall well-being, rather than productivity gains. Studies have found that even if multitasking makes you more productive in the short term, it can lead to feelings of stress, frustration, and lower self-reported productivity. Additionally, chronic multitaskers are less able to fully focus their attention on tasks, leading to poorer learning outcomes. Technology plays a significant role in both our tendency to multitask and our elevated stress levels, with frequent interruptions from notifications and emails contributing to decreased focus and increased stress. Tools such as batching notifications, using productivity apps, and implementing self-imposed limits on distractions can help individuals adopt more productive habits and reduce stress. By limiting distractions and building better habits, individuals can improve their ability to focus, learn new things, and feel happier and more productive.
