Sleep has often been overlooked compared with diet and exercise, but research increasingly shows it plays a central role in overall health.
Poor sleep is linked to a range of conditions, including cardiovascular disease, weakened immunity and mental health challenges.
Scientists studying circadian rhythms — the body’s internal clock — have found that regular sleep patterns are essential for maintaining physical and cognitive function.
Modern lifestyles can disrupt sleep. Exposure to screens, irregular schedules and stress are common factors affecting sleep quality.
At the same time, awareness is growing. Sleep tracking technologies, workplace wellbeing initiatives and public health campaigns are encouraging better habits.
Experts suggest sleep should be treated as a foundational element of health, not a secondary concern.
In that sense, improving sleep may be one of the simplest — yet most impactful — ways to improve overall wellbeing.
