In addition, sleep deprivation can have serious effects on your health and mental abilities. Inadequate rest impairs our ability to think, to handle stress, and maintain a healthy immune system. Furthermore, not enough sleep can control our moderate our emotions causing irritability, anxiety, rage and anger and depression.
