Some feel anxious because of work pressure, but there are others who feel agitated and stressed when they are not engaged. Legendary Bollywood actor Amitabh Bachchan falls into the latter group. The 83-year-old has never really retired and has continued to entertain his fans and rule their hearts through his work. Over the years, there have been several interviews about his routine, discipline, and how the actor likes to stay busy. In a recent blog, he opened up about feeling anxious and uneasy when he does not work every day.In his blog, Mr Bachchan wrote, “You wonder why the day is not behaving the way you normally wish it to be. So, if there is some understanding of this element within us, then ‘may there be peace and calm around us’, but for some, it never happens, and that is an added anxiety. Living in anxiety, they say, is harmful for the mind and body, and leading an anxious day on the weakness of this phenomenon is unnecessary (sic).”Through his post, the 'Piku' actor revealed that a day spent lazing around seems 'disturbing.' He continued to say that when one does not work every day as per a schedule, the day becomes a 'mystery of deeds', which hints at the importance of structure and how a strong routine can shape one's mental health. But what contributes to the anxiety of not being occupied?Why do some people feel anxious when not working?According to experts, many people underestimate the importance of a routine for mental health. Humans are wired to depend on structure for stability, and when that is eliminated, the mind has to reorganise internally. This does not come easily. However, from a psychological perspective, this can lead to an excessive cognitive load, triggering a stress response. This stress response can manifest as anxiety, uneasiness, irritability, or restlessness.How to cope with the stress on a lazy day?Experts say that unproductiveness need not be associated with work itself—one can also engage in household chores or a hobby to feel productive and engaged. On a free day with no schedule, creativity can offer an escape. One can try going for a walk, cooking, taking breaks from screens every few minutes, and even playing sports. This helps regulate the nervous system. It can support not just physical but also emotional recovery. This way, when the brain takes a break, it does not feel empty and recovers faster.How to feel productive on your day off?When not at work, there are some simple ways to avoid falling into a slump.
