Biotechnology is emerging as a cheaper, safe and permanent cure for many diseases. Its contribution to health care appears as a boon.
Insomnia may be a consequence of disease/medication (secondary insomnia), or it may occur completely independently (primary insomnia).
Insomnia also varies in how long it lasts and how often it occurs. It can be short-term (acute insomnia) or can last a long time (chronic insomnia). It can also come and go, with periods of time when a person has no sleep problems. Acute insomnia can last from one night to a few weeks.
