A healthy person needs 7-8 hours of good sleep every day. Lack of sleep can cause many physical and mental problems. The main reasons for this are:
Mental stress and anxiety: The biggest cause of insomnia is stress. Not being able to calm down due to problems at work and family worries disrupts sleep. Thinking unnecessarily while going to bed forces the brain to stay awake.
Use of digital screens: Using mobile phones, laptops and TV just before going to bed can affect sleep. The ‘blue light’ from these devices prevents the production of the sleep-inducing hormone melatonin.
Irregular sleep habits: Sleeping at different times every day and sleeping for a long time during the day disrupts the body’s natural sleep cycle (Circadian Rhythm). This causes you to not fall asleep on time at night.
Excessive caffeine use: Drinking tea and coffee late at night can disrupt your sleep. Caffeine stimulates the nervous system and keeps the body alert for hours. In addition, tobacco use and alcohol consumption reduce the quality of sleep.
Health problems and medications: Chronic pain, snoring, sleep apnea, and frequent urination can disrupt sleep. Insomnia can also be a side effect of some serious medications.
