SLEEP: AN INSIGHT TO THE NEGLECTED COMPONENT OF HEALTHY LIFESTYLE

Abstract

Human beings, exhibit daily patterns of rest and activities and until a few years ago,
little is known about the sleep process, its benefits, and the possible consequences of
inadequate sleep. Scientific advances and input from diverse clinical disciplines have
enriched the study and management of sleep disorders. Multiple evidences are now
available to show that the sleep process is essential to the improvement and maintenance
of mental health (like mood stabilization, good memory, cognitive performance),
physical health (like healthy cardiovascular and metabolic systems), and productivity in
the society. Poor quality and quantity of sleep has been associated with increased risk
for accidents, hypertension, cardiovascular diseases, diabetes mellitus, mental disorders,
some cancers, and ultimately increase mortality. Health promotion programmes with
focus on healthy living and lifestyle modification is essential in the attainment of
individual sleep need and repayment of sleep debt. This article provides a brief insight
into the often misunderstood purpose and architecture of sleep, the benefits of adequate
and restorative sleep, and the health consequences of inadequate sleep, especially as it
relates to sleep need and sleep debt. It concludes by suggesting practical sleep hygiene
and lifestyle intervention measures that can be adopted to harness the full health benefits
of this often-neglected component of promotive healthcare.
