Low Energy/Drowsiness

The sensation of sleepiness that we usually feel before our night’s sleep, that paves its way into a slight lack of consciousness is termed as Low Energy/Drowsiness. If you have had a poor night’s sleep, feeling drowsy is obvious. But feeling drowsy throughout the day can reduce the quality of life, impact our work profile, reduce performance, and deteriorate our overall wellbeing. Clinically is termed as excessive daytime sleepiness or hypersomnia which is the excessive urge to fall asleep and in severe cases, it is the fight to even stay up awake. Mostly, Low Energy/Drowsiness is not a matter of concern until it interferes with our ability to performs our daily tasks, contribute to work, or even while we are sitting ideal. When Low Energy/Drowsiness becomes a routine, the causes and manifestations should be considered as sustained levels of Low Energy/Drowsiness that can hamper and make our daily life difficult. 

Most of the time depression, anxiety, stress, and boredom can all contribute to excessive sleepiness, but these ultimately lead to fatigue and apathy.

Usually, Low Energy/Drowsiness is a symptom, but if ignored and not taken care of, it can lead to a chronic illness that affects the person not only physically, but mentally, socially, and spiritually as well. Ranging with a variety of causes, risk factors, and complications, it is important to note the slightest changes in sleep patterns and wakefulness in daily routine.  

Causes of Low Energy/Drowsiness

Anything that delays or interrupts the normal sleep cycle or pattern should be considered a cause of Low Energy/Drowsiness. Things or causing factors that can cause irregular sleep patterns are:

• A disturbing sleep environment: uncomfortable bed, too many lumpy pillows, nightclothes are not comfortable, excessive lighting in the room, the inadequate temperature of the room, noises in and around the house, bright LED displays of clocks or anything in the room, snoring of partner, babies waking up at night time

• Medical illness, hospitalization, and chronic pain 
• Presence of sleep disorders like sleep apnea, restless leg syndrome, periodic limb movements, narcolepsy, Sleepwalking and talking, night terrors and nightmares, REM disorder, bruxism (teeth grinding), enuresis (bedwetting)
