Down with viral for a couple of days, did not manage to get adequate sleep. Wondered what makes us stay awake or sleep. Glanced through some old notes and Googled to find the cause—the Hypothalamus that resides in the lower part of the brain. Hypothalamus not only manages wakefulness and sleep, but also regulates body temperature and performs host of other functions. So next time, you lose sleep, don't blame people or situations around, blame the Hypo........instead.
