Blue light glasses & sleep deprivation: how does it help?

We’ve all been there – studying right before the finals in college is the norm. Though we’ve mastered the skill of last-moment studies, late night learnings can harm our health and sleep quality. From sophomore to final year students in the UK, the average bedtime is around 1:30 AM. 

Most of the course work and preparation today is done on computer or phone screens. College students have specially built up a bad reputation for sleeping during lectures after staying up late at night. The adverse effects are mostly fatigue, eye strain and headache, leading to the popularity of  glasses usage.

Impacts of sleeping late at night

Insomnia – There’s been a surge in disorders ranging from insomnia to excessive daytime sleepiness among students. Which leads to tired and exhausting physical and mental health. Lack of sleep brings various sleep-related issues like instant irritation, difficulty in concentration, gloomy mood and behaviour. 

Weak Immune System – Sleep deprivation can also weaken our functioning of the immune system where we lose the ability to fight off infections. It can make our body more prone to respiratory infections like cold and flu. It’s absurd to think that lack of sleep can lead to such adverse effects but not realising the importance of enough hours of sleep is alarming. 

Mental disorder – Poor sleeping habits not just invite physical illness but also a high risk of mental disorder among college students. According to Harvard meds, sleep and mental health are correlated. Poor sleep affects our psychological state and hinders our mental health. Sleep deprivation is common among patients with depression, anxiety, bipolar disorder and attention deficit hyperactivity disorder (ADHD).

Obesity – Lack of sleep has 30% higher chances of gaining weight compared to people who got 7 hours of sleep every night. It’s very difficult to stop the temptation of craving some snacks at night which if continues, would make your obese over some time. Since sleep-deprived individuals are too tired, there’s zero chance they exercise or burn their calories. Staying late at night with no awake increases the opportunity to eat. Also, lack of sleep causes an imbalance in the key hormones that control-appetite so you are bound to feel hungry at night.

What causes sleep deprivation in students?

Digital devices like smartphones, laptops or computers have led to an increase in late-night sleepers. One of the largest percentages of technology users is young kids aged 18-25 students. Social media usage is the biggest catalyst in youngsters sleeping hours. Many teens don’t consider giving any importance to sleep or timely bedtime routine. A large proportion of college students use social media before going to bed which increases from 15 minutes check to more than 2 to 3 hours consumption. 

According to the National Sleep Foundation poll on electronic use, about 30% of students get awakened by a late-night text, email or calls. About 64% of the kids use electronic music devices, 60% use laptops while 23% of them play video games before going to bed. These habits lead to a significant drop in sleeping habits and make students drowsy the next morning. 

Another cause of sleep deprivation is the blue light rays emitted from the screen. The blue light is a ray penetrated from the screen that reaches the retina and causes severe eye problems and discomforts like eye strain, dry-eyes, burning sensation, blurry vision, redness, itchiness and headaches. 

Apart from vision discomfort, it works its way to damage your sleeping habits. The sleep-inducing hormone melatonin is suppressed from getting released into our body by blue light rays, leaving your body awake, alert and energetic even if it’s midnight. Under the blue glare of your computer screen, you almost forget to sleep and continue for hours scrolling or texting at night.
