Chronic sleep deprivation can lead to several serious health consequences, such as impaired cognitive function, weakened immune response, and increased risk of chronic conditions like obesity and diabetes. Mental health issues such as anxiety and depression may also worsen due to insufficient sleep. Additionally, sleep deprivation can impair physical performance and reaction times, increasing the likelihood of accidents. Long-term lack of sleep is linked to higher risks of cardiovascular diseases and can significantly decrease overall quality of life.
