Sleep has become a luxury for many in Gen Z. Between constant notifications, academic pressure, social expectations, and an “always-online” culture, this generation is facing a sleep crisis that goes far beyond simply staying up too late. Experts say that their mental health, biology, and modern lifestyles all play a role in why so many young people today are running on empty.

How deep is the sleep crisis among Gen Z?

According to a 2022 study published in ScienceDirect, many Gen Z individuals are sleeping for only about six hours a night—far less than the recommended eight to 10 hours for adolescents and young adults. Chronic sleep deprivation among this age group is not just a matter of poor bedtime habits. It deeply affects brain function, emotional health, and overall well-being.

Is technology keeping Gen Z awake?

One of the main reasons behind Gen Z’s struggle with sleep is their heavy reliance on digital devices. Smartphones, tablets, and laptops keep the brain active long after sunset. The blue light emitted from these screens interferes with melatonin, the hormone that helps the body prepare for sleep.

Social media, streaming platforms, and online gaming often encourage what researchers call “sleep procrastination,” where rest is sacrificed for late-night scrolling or binge-watching. Studies show that simply setting aside devices an hour before bedtime can help teenagers gain an extra 21 minutes of sleep each night, equivalent to almost two additional hours of rest during a school week. However, the fear of missing out (FOMO) and algorithm-driven engagement make it increasingly hard for young people to switch off.

How does stress and lifestyle impact their sleep?

Health experts agree that Gen Z faces unprecedented levels of psychological pressure. Economic uncertainty, academic competitiveness, and constant social comparison contribute to elevated stress hormones, which disturb natural sleep cycles.

This generation reports the highest rates of psychological distress globally. Sleep deprivation then worsens these conditions, increasing the risk of anxiety, depression, and even suicidal thoughts. Most young people sleep for only 6.5 to 7.5 hours a night, leading to fatigue, poor focus, and lowered immunity.

Puberty also naturally shifts the body’s internal clock, making young people biologically inclined to stay awake later. Early school start times, demanding schedules, irregular sleep routines, caffeine consumption, and the absence of calming evening rituals all add to the problem.

A lack of daytime activity and sunlight further reduces the body’s sleep drive, leaving Gen Z feeling constantly tired, less productive, and mentally drained.

Could undiagnosed sleep disorders be to blame?

Sleep experts are noticing a rise in diagnosed sleep disorders among young people. Conditions such as insomnia, sleep apnoea, restless leg syndrome, parasomnias, and narcolepsy not only interfere with rest but also worsen mental and physical health if untreated.

For example, insomnia can cause depression, weight gain, and poor concentration, while sleep apnoea may lead to daytime exhaustion, memory lapses, and high blood pressure. Tests like polysomnography, EEG scans, and genetic assessments can help identify these issues. Treatments including cognitive behavioural therapy for insomnia (CBT-I), melatonin supplements, and consistent sleep hygiene practices can restore better sleep patterns.

How can Gen Z reclaim restful sleep?

Experts suggest that solving the sleep problem among Gen Z requires more than just willpower, it needs a balanced lifestyle and supportive environment. Digital curfews, blue-light filters, and screen-free periods before bed can calm overstimulated minds. Relaxation techniques such as mindfulness, deep breathing, and meditation can lower stress levels and prepare the body for rest.

The physical environment plays a big role too. A dark, cool, and quiet room, a supportive mattress, regular wake-up times, and a nutrient-rich diet containing calcium, magnesium, fibre, and vitamins all contribute to restorative sleep. Even simple habits like stepping outside for 30 minutes of morning sunlight or following a gentle bedtime routine can make noticeable improvements.

Experts also stress that this issue cannot be left to individuals alone. Schools and workplaces should align schedules with natural sleep rhythms, delay start times when possible, and raise awareness about the importance of quality rest.

In the end, Gen Z’s struggle with sleep is not about laziness or bad habits. It’s a reflection of a generation caught between high expectations and constant stimulation. Reclaiming rest might just be the first step toward reclaiming balance.
