Everyone has his or her own perception when it comes to insomnia – the sleepless nights we go through – but your perception may be far from the truth, according to scientists.
Some people say insomnia arises when one is stressed and unable to resolve certain challenging issues. Others say they experience sleepless nights when they are overjoyed about something either about to happen or that has already happened, which raises their adrenaline and causes a lack of sleep.
