Sleep deprivation: The lifestyle crisis nobody talks about
In a world that celebrates productivity, hustle culture, and constant connectivity, sleep has quietly become one of the most neglected aspects of modern life.
While people openly discuss fitness, healthy eating, and mental wellness, sleep deprivation remains a hidden lifestyle crisis affecting millions every day.

For many, a good night’s sleep has become a luxury rather than a necessity. Long working hours, social media scrolling, streaming platforms, financial pressures, and family responsibilities often push sleep to the bottom of the priority list.
The result is a society that is increasingly exhausted, yet continues to function as if fatigue is normal.
According to Thomas, Johnson, a physician assistant who specialises in pulmonology and sleep medicine, insufficient sleep can disrupt hormone levels that regulate hunger, potentially leading to overeating, weight gain, and an increased risk of cardiovascular issues.
Effects of lack of sleep on the body
Central nervous system
In his study, the central nervous system is the main information highway of your body; hence, sleep is necessary to keep it functioning properly. Chronic insomnia can disrupt how your body usually sends and processes information.
He says you may also find it more difficult to concentrate or learn new things. The signals your body sends may also be delayed, decreasing your coordination and increasing your risk for accidents.
Sleep deprivation also negatively affects your mental abilities and emotional state, as you may feel more impatient or prone to mood changes. It can also compromise decision-making processes and creativity.
You may also end up experiencing microsleep during the day. During these episodes, you’ll fall asleep for a few to several seconds without realizing it.
Cardiovascular system
Thomas Johnson further explains how Sleep affects processes that keep your heart and blood vessels healthy, including those that affect your blood sugar, blood pressure, and inflammation levels.
He says sleep also plays a vital role in your body’s ability to heal and repair the blood vessels and heart.
People who don’t sleep enough are more likely to get cardiovascular disease. One analysis linked insomnia to an increased risk of heart attack and stroke.
Addressing the sleep crisis requires both personal and societal change.
Individuals can start by establishing consistent sleep schedules, reducing screen time before bed, creating restful sleeping environments, and prioritising sleep as an essential part of self-care.
