“Here’s How Sleep Has Changed Over the Last Century”

Sleep has transformed remarkably over the last century, shaped by lifestyle, technology, and work culture changes. In the early 1900s, many people maintained a more natural sleep schedule due to limited access to artificial lighting, often sleeping in two phases with a wakeful period in between. As electric lighting became common, people shifted towards single, consolidated sleep patterns. The Industrial Revolution and the 24-hour economy further influenced this, with work demands and shift-based jobs disrupting natural sleep rhythms.

The rapid rise of technology in recent decades has had a profound effect on sleep habits. Screens emit blue light, which delays melatonin production and keeps people alert later into the night. The convenience of smartphones has also led to many individuals spending pre-sleep hours scrolling through social media or emails, affecting both sleep duration and quality.

The culture of "hustle" and productivity further influences modern sleep, as societal pressures often reward longer work hours over rest. As people attempt to maximize productivity, sleep is frequently sacrificed, leading to higher rates of sleep deprivation and related health issues. Chronic sleep deprivation has become a common concern, linked to a range of physical and mental health problems.

Recent research has emphasized the vital role of sleep for health, resilience, and overall well-being. Studies have shown that good sleep is essential for memory consolidation, immune function, and emotional regulation. With growing awareness of these benefits, the last decade has seen a rise in wellness movements advocating for better sleep hygiene, natural sleep aids, and even sleep-focused technology to encourage healthier sleep habits.

Today, as people increasingly recognize the importance of quality sleep, the approach to rest has started to shift once more. Apps and wearable devices track sleep patterns, promoting better habits, while wellness programs and businesses highlight the benefits of rest for productivity and mental health. This changing perspective represents a growing movement toward prioritizing sleep as a fundamental aspect of modern health and productivity.
