Nidra is said to occur due to Tamas guna abundance in body while Satva guna abundance helps one to wake-up from sleep. Therefore, abundance of these gunas in surroundings during day & night cycle naturally one feels sleepy or awakened. Raja guna affects movements of manas which is the main component of sleep pathway and thus this disturbs the normal pattern of sleep.
