What happens when you try to sleep after a long day of work? Do you instantly fall asleep? or, do you keep trying to sleep but tossing and turning the entire night? If you are in the latter section, then you are not alone. Lack of sleep or rather lack of solid, restful sleep is becoming an issue of global concern. WHO (World Health Organization) has termed this as a global epidemic. Keeping up with a fast-paced life, dealing with constant stress, night shift work, and study pressure significantly reduce your sleep.
