What lack of sleep does to your work
Impaired decision making. When you lack sleep, you are deprived of a sound mind which fuels the abilities to evaluate scenarios and pass judgment based on those assessments. These abilities are crucial to the execution of any task that requires logical reasoning from complex cognition. Without an adequate grasp of a sound mind, you may be more prone to making mistakes at work due to an increased tendency to make impulsive and poorly thought-out decisions or merely slowing down work progress in the more difficult attempt to prevent the former.
Limited learning and memory
capacities. The process of learning, retaining and improving skills and abilities heavily rely on your working memory capacity, one which determines the performance of your cognitive online (real-time) processing. Research suggests that while you are asleep, your memory systems are still active and sleeping significantly strengthens existing memories. During Rapid Eye Movement (REM) sleep, your brain also cuts off unnecessary neuron connections while maintaining others; meaning sleep improves your memory by selectively both strengthening and eliminating formed neural connections. In a state of sleep deprivation, your capacity for efficient memory retention is substantially disrupted, hindering productive growth.
Toxicity towards physical and
emotional health. Health implications of insomnia, while never usually the priority, should never be trivialized. Sleep plays an essential role in your physical health by both reinforcing your immune system against infections via boosting protective cytokine production and lowering your risk of diabetes, obesity, and cardiovascular diseases. Insufficient sleep will positively contribute to a decline in your physiological state, negatively impacting your work performance. It has been found that sleep deprivation can compromise your cognitive processing and amplify the smallest amount of emotional turmoil, making you more irritable and erratic. This impedes your executive functions, rendering you less productive.
