BRAIN WAVES
This objective measure uses electrodes attached to the scalp to measure electrical activity in the brain.
What is an electro-encephalography (EEG)?
This is the length of time it takes a person to fall asleep.
What is sleep latency?
This condition occurs when an individual gets poor-quality or insufficient sleep to sustain optimal functioning.
What is sleep deprivation
This occurs when a person gets insufficient quality or quantity of sleep for an extended period, resulting in poor functioning.
What is chronic sleep deprivation?
Phones, laptops and tablets can make it harder to wind down before sleep because they produce this type of light and provide mental stimulation.
What is blue light?
These waves have the highest frequency and are typically present during the early stages of sleep.
What are alpha waves?
This broadly refers to work that occurs during the period when a person would normally be asleep, including night, early morning and rotating shifts.
What is shift work?
This type of sleep deprivation occurs when insufficient or poor-quality sleep affects optimal functioning over a short period of time.
What is acute sleep deprivation?
Chronic sleep deprivation can increase cortisol levels, interfere with immune functioning and place stress on the heart.
What is heart disease?
This sleep hygiene strategy involves keeping the times you fall asleep and wake up regular and consistent to help regulate the circadian rhythm.
What are consistent sleep patterns?
These brain waves have a lower frequency and higher amplitude than alpha waves and are associated with sleep.
What are theta waves?
This refers to medicine or another substance that can have a physiological effect and impact the sleep-wake cycle.
What are drugs?
A person experiences increased irritability, emotional volatility and rapid mood swings after several nights of insufficient sleep.
What is mood?
Insufficient sleep can alter hormones that regulate appetite, increasing hunger and encouraging greater intake of high-energy foods.
What is obesity?
A student regularly sleeps in a room with a comfortable mattress and pillows, an appropriate temperature and minimal noise and light.
What is the creation of a healthy sleep environment?”
These are bursts of rapid, rhythmic brain activity that are important for learning and memory.
What are sleep spindles?
A person finds it difficult to fall asleep because their bedroom is too hot, bright and noisy, and their electronic devices are disrupting their sleeping conditions.
What is the sleep environment?
After a night of insufficient sleep, a student struggles to concentrate and experiences lapses in attention. Slower brain processing and impaired working memory may be contributing to this effect.
What is attention?
A person experiencing chronic sleep deprivation develops ongoing difficulty falling asleep and frequently wakes during the night.
What is insomnia?
According to the information provided, phones, laptops and tablets should ideally be stopped around 30 minutes before sleep because they produce blue light and mental stimulation.
What is management of electronic devices?
An EEG shows that a person's brain activity has slowed considerably, with slow waves indicating that the person has entered a deeper state of sleep.
What are delta waves?
A student has several major assessments approaching. They feel constantly stressed and alert at night, making it difficult to fall asleep.
What are stressors?
After being sleep deprived, a person takes longer to respond to a sudden event and also experiences blurred vision and increased sensitivity to light. Identify the two physiological effects being demonstrated.
What are reduced reflex speed and impaired vision?
After a prolonged period of insufficient sleep, a person experiences impaired emotional regulation and worsening symptoms of excessive worry.
What is anxiety?
A four-week study with 38 participants to investigate how limiting bedtime mobile phone use affected these five areas: mood, working memory, pre-sleep arousal, sleep quality and sleep habits.
What is the He et al. (2020) study?
