If you’ve spent a night tossing and turning, you already know how you’re going to feel tired and groggy the next day. But spending 7-9 hours of shut-eye every night does more than just make you feel dull and sad.
The long-term effects of sleep deprivation are real.
It drains your mental faculties and puts your physical health at real risk. Science has linked sleep deprivation to a host of health problems, from weight gain to a weakened immune system.
Read on to find out what causes lack of sleep and how it affects certain body functions and systems.
Reasons for lack of sleep
Briefly, insomnia is associated with persistent lack of sleep or reduced quality of sleep. Getting less than 7 hours of regular sleep can have health consequences that affect your entire body. It can also be caused by sleep disorders.
Just like your body needs air and food to function at its best, you need sleep. When you sleep, your body heals itself and restores its chemical balance. It helps your brain create new thought connections and retain memories.
Without enough sleep, your brain and body systems will not function properly. It significantly reduces your quality of life.
A 2010 study found that getting too little sleep at night increases the risk of early death.
Notable symptoms of sleep deprivation include:
fatigue during the day
Stimulants like caffeine aren’t enough to satisfy your body’s need for sleep. In fact, they make it harder to fall asleep at night and make insomnia worse.
This, in turn, leads to insomnia at night and then to caffeine during the day to combat the tiredness of shut-eye.
Chronic sleep deprivation can disrupt your body’s internal systems and cause more than just the initial symptoms listed above.
