Sleep deprivation refers to a condition where an individual is not getting enough sleep or rest. This can be due to various reasons such as stress, anxiety, medical conditions, lifestyle choices, or other factors that disrupt normal sleep patterns. When someone experiences sleep deprivation, it means they are not getting the recommended amount of sleep which is typically 7-8 hours per night for adults. The consequences of sleep deprivation can be significant and may include impaired cognitive functioning, mood disturbances, decreased productivity, weakened immune system, increased risk of chronic health conditions such as diabetes or heart disease, and even accidents due to drowsiness while driving. Therefore, getting enough sleep is crucial for maintaining good physical and mental health.
