Sleep plays a role in academic performance, reports Australian website

Sleep is known to be important for learning — it’s crucial for consolidating long-term memories. Missing out on sleep can also impair attention and short-term memory. In a study of high-school students, researchers found that sacrificing sleep for extra study time was actually counter-productive and resulted in increased academic problems the following day.

We also now know that the blue light emitted by smartphones, tablets and computers suppresses melatonin production, meaning that using these devices at night can interfere with the body’s natural sleep cycles. The teenage brain seems to be more sensitive to the effects of blue light; for teenagers to get enough sleep, avoid late-night use of devices that emit blue light, or use blue light reduction apps like Apple’s Night Shift.
