Reduced performance and focus
The sleepless nights often tend to cause sleepiness during the daytime, thus causing the person to become dull during the day. The performance level of the person, be it a school student from a teenager or an adult at work, lowers subsequently. The main reason is the daytime sleepiness, which causes a lack of focusing on your work and studies. The sleepless nights not only cause dullness throughout the day but also cause pain in the head, which never goes until you fall asleep properly.
