The importance of sleep can not be over-emphasised. A lack of sleep may be reflected in either physical health or mental health or both. It's also important to know that not only does the quantity (number of hours) of sleep matter but also the quality of it. So ask yourself: how well did you sleep?
Disturbed sleep could cause moodiness, daytime irritability and sleepiness, unexplained headaches and un-refreshed sleep. It has also been proven to be strongly associated with systemic problems like hypertension, diabetes mellitus and serious cognitive issues.
Sleep disturbance or interruptions may be caused due to external factors such as awkward timings of sleep (night shifts/parent of young children), snoring partners, alcohol consumption, smoking, caffeine or excessive food at night, or due to anxiety and stress. Some bodily factors like snoring and improper breathing during sleep also affect the quality of sleep.
Snoring has been identified as a leading reason for improper sleep or poor quality of sleep. And, unfortunately, it is known to be identified in over 40% of the adult population. Further, of those identified, about 20% have been diagnosed with a more serious, life threatening disorder known as sleep apnoea.
