Blue Monday and Light Therapy Glasses: A Brighter Way to Beat the Winter Blues

Why is it difficult for me to wake up feeling refreshed?

If you wake up feeling groggy and listless in the morning, you are not alone. According to a 2023 study, as many as 60% of young adults don’t feel rested after waking up. Furthermore, not getting enough hours of shut-eye is not the only reason for feeling low on that morning energy.
There are several biological, environmental, and psychological factors at play when you transition from sleep to wakefulness. One of the less-talked-about phenomena that might make this transition difficult for you is sleep inertia.

Exposure to natural light

Your body is governed by an internal biological clock that responds to light cues. When exposed to natural light throughout the day, this system springs into action, keeping you awake and refreshed.
When there is no natural sunlight, the system shuts off, helping you get the much-needed rest at night. Unfortunately, when you are not exposed to enough natural light, the system can falter, ruining the natural rhythm and causing sleep disorders.

So, how do you feel rested by reinforcing this natural cycle?
Try to get sunlight exposure for at least 30 minutes daily, preferably in the morning after you wake up. It will help your body regulate the levels of the sleep hormone melatonin, making it easier for you to fall and stay asleep and wake up with energy.
Light therapy is a perfect alternative for those who can’t get enough natural sunlight. It is a great way to mimic sunlight exposure to regulate your melatonin and align your day-night cycle.
When you use systems like light therapy Lamp Drive from Luminette, it signals the brain to wake up, reinforcing a regular sleep-wake cycle.

Light therapy can be especially useful if you live in an area with scarce natural morning light or if your work schedule makes it impossible to enjoy natural light.
Using light therapy systems daily can significantly improve your sleep, helping you wake up more fresh and energized.

Not getting enough sleep

If you suddenly wake up from deep REM sleep, your brain might trigger sleep inertia. The abrupt transition doesn’t allow your brain to gradually prepare for the wakeful stage, resulting in disorientation and fatigue.

Sleep cycle deprivation

You might get caught in the sleep inertia cycle if you make a habit of not getting enough sleep. When you are sleep-deprived, your body craves more rest, and waking up feels like a Herculean task.

Inadequate sleep quality

Getting a stipulated number of hours in the sac is not enough for restful slumber. You need to have proper sleep cycles of REM and NREM sleep to feel fully rested.
If you have medical conditions like sleep apnea, your sleep cycles might get disturbed at night, resulting in poor-quality sleep. When you wake up from such a sleep, your brain is not fully rested, and you feel dizzy and tired, even after spending 8-9 hours in bed.

What is sleep inertia?

In simple words, sleep inertia refers to grogginess and impaired performance immediately after waking up.
While we have all experienced sleep inertia occasionally, it becomes a problem when it lasts for several minutes or even hours.
The phenomenon was first identified in the 1950s among US Air Force pilots. The pilots reported feeling especially groggy, which impairs their performance and cognitive ability during early morning flight drills. When you wake up, different parts of your brain don't activate at the same speed. Your motor functions might be working, but you prefrontal cortex - responsible for decision-making , attention, and complex thinking - takes longer to fully "boot up." This creates the sensation that your mind is lagging behind your body. Sleep inertia occurs because your brain needs time to transition from sleep mode to wake mode. During sleep, your brain produces adenosine and other sleep-promoting chemicals. Upon waking, these substances don't immediately disappear, leaving you feeling drowsy and mentally foggy until your system clears them out.
Most people experience sleep inertia for 15-30 minutes after waking. However, severity can vary based on several factors including which sleep stage you wake up from, how much sleep debt you have accumulated, your individual body's clock timing, and environmental factors like light exposure. Waking up from deep sleep typically causes more severe inertia than waking from lighter sleep stages.
While mild morning grogginess is normal, sleep inertia becomes concerning when it lasts longer than an hour after waking, significantly impacts your daily performance, occurs despite getting adequate sleep, or interferes with safety-sensitive activities like driving. Today's lifestyle factors such as irregular sleep schedules, blue light exposure before bed, and poor sleep quality can worsen sleep inertia, making it more severe and longer-lasting than our ancestors likely experienced.
