Waking up suddenly, especially when startled from a deep sleep, is generally not harmful in the long term, but it can cause temporary physical and mental stress responses [1].
Sleep inertia refers to the cognitive and sensory-motor impairments that take place immediately when waking up. It occurs when a person wakes suddenly from a deep sleep. They may experience: drowsiness or disorientation.
Additionally, some people may find that waking up abruptly actually helps them feel more alert and energized in the morning. Overall, while waking up abruptly to an alarm clock may not be ideal, it is unlikely to cause any serious harm in most cases.
Traditional alarm clocks can interrupt your sleep and leave you feeling groggy because they wake you up abruptly. This sudden awakening can negatively affect your sleep quality and overall well-being. A more gradual wake-up process is essential for a smoother and more pleasant start to your day.
10 hours before bed: No more caffeine. 3 hours before bed: No more food or alcohol. 2 hours before bed: No more work. 1 hour before bed: No more screen time (shut off all phones, TVs and computers).
Koalas are thickset arboreal marsupials with a thick grey fur. Found only living in Australia, they mainly live in the eucalyptus trees and spend around 22 hours of their time sleeping (90%). They spend the other 10% of their day eating and sitting around.
The convenience of access to social media has contributed to 93% of Gen Z admitting to staying up past their bedtime (Aloddi et al., 2023). The light weight design of devices makes it easy for individuals to stay in their beds for hours scrolling.
The military sleep method emphasizes well-researched techniques that can promote a sense of calm and relaxation to help your brain and body prepare for sleep. But it's worth pointing out that no studies have been done on the method itself.
Happiness. A large-scale genetics study recently conducted by Exeter University revealed that people who are “early birds” have greater levels of happiness and are at a lower risk of depression compared to those who are “night owls”.
Best survival rates were found among those who slept seven hours a night. A group sleeping eight hours was 12% more likely to die within the six year period than those sleeping seven hours, other factors being equal. Even those with as little as five hours lived longer than those with eight hours or more nightly.
Signs You're Not Getting Enough Core Sleep
Sleeping on your front is considered unhealthy because it can inhibit breathing and cause irregular curvature of the spine. The turning of the head to one side when sleeping in this position is another cause of such a curvature. All of this can lead to inflammation and pain in the neck muscles in addition to back pain.
Long-term sleep disruption may also worsen the symptoms of a variety of gastrointestinal disorders. Ultimately, it has been suggested that the physiologic consequences of disrupted sleep may be just as damaging as those of short sleep duration.
People with apnea often toss and turn and otherwise show signs of restless nighttime sleep. If you find yourself kicking, thrashing, jerking or waking up under a twisted pile of disheveled sheets, apnea might be a possible cause. When you're struggling to breathe at night, your sleep becomes disrupted.
Stomach sleeping is the least common position. It may help prevent snoring, but can strain your neck and lower back.
Own Your 3-Foot Space In Navy SEAL training, there's a simple but profound principle: Own your 3-foot space. It means focusing on what's directly within your control—your actions, your attitude, your effort—no matter how chaotic the environment around you becomes.
A prime example is the box breathing technique, famously used by the Navy Seals, known as the 4-4-4-4 method. This simple yet effective method involves a cycle of inhaling for 4 seconds, holding the breath for 4 seconds, exhaling for 4 seconds, and then pausing for 4 seconds before the next inhalation.
Whilst boomers and millennials may use the 😂 emoji, this has long since been deemed 'uncool' (or 'cheugy') by Gen Z. Instead, this has been replaced by the skull (💀) or the crying emoji (😭), dramatising the idea of 'dying with laughter'.
Across much of the world, it is no longer middle-aged adults who are the most miserable. Instead, young people, especially Gen Z, are reporting the highest levels of unhappiness of any age group.
Some evidence suggests that high IQ is associated with later sleep patterns. However, it is unclear whether the relationship between IQ and later sleep is due to biological or social effects, such as the timing of working hours.
Among the most rested countries surveyed by Sleep Cycle, an app that tracks how much shuteye people are getting, New Zealand comes top with the average Kiwi clocking up in excess of 7.5 hours per night. Finland, the Netherlands, Australia, the UK and Belgium all rank highly for sleep, too, with Ireland close behind.
The answer is “probably.” Research has shown that many animals experience a sleep phase similar to humans known as REM (Rapid Eye Movement) sleep, which is closely associated with dreaming. This phase is characterized by increased brain activity and is when most vivid dreams occur.
