Stress and anxiety: Worries, anxieties and excessive stress can keep the mind alert and prevent it from relaxing, making it difficult to fall asleep.

Poor sleep habits: Irregular sleep schedules, excessive napping during the day and inconsistent bedtime routines can disrupt the body's natural sleep-wake cycle.

Environmental factors: Noise, light, temperature and uncomfortable bedding cause difficulty in sleeping thereby leading to a disturbed sleep cycle. Correcting these factors can help one in getting deep sleep. 

Caffeine and stimulants: Consuming caffeine or other stimulants like alcohol a few hours before bedtime can interfere with sleep.

Electronic devices: Exposure to screens before bedtime, be it a laptop or a mobile phone, can hinder the production of the sleep hormone melatonin, making it harder to fall asleep.
