Understanding Sleep Disturbance: Causes and Factors

Sleep is essential for overall health and well-being, yet many people struggle with sleep disturbances such as insomnia or difficulty falling asleep. These challenges can stem from a range of complex factors. While every individual’s situation is unique, the following are some of the most common contributors to sleep disturbances:

• Sedentary Lifestyles: Lack of physical activity during the day can reduce the body’s need for restorative sleep.
• Irregular Sleep Patterns: Disruptions to your circadian rhythm, such as inconsistent bedtimes, make it harder to establish healthy sleep cycles.
• Shift Work: Alternating schedules greatly disturb the body’s natural sleep-wake cycle, often leading to insomnia.
• Seasonal Variations: Longer daylight hours in summer can delay melatonin secretion, particularly in regions with significant latitude shifts.
• Stress and Anxiety: Overthinking and heightened stress levels interfere with the ability to relax and fall asleep.
• Breathing Disturbances: Sleep apnoea and similar conditions raise adrenaline levels, disrupting the body’s ability to stay at rest.
• Hormonal Factors: Thyroid imbalances, such as overactive thyroid, can cause insomnia, while underactive thyroid often results in excessive sleepiness.
• Poor Sleep Hygiene: Blue light exposure from phones, TVs, or computers suppresses melatonin and disrupts sleep.
• Excessive Sleep: Oversleeping during the day can make it difficult to fall asleep at night.
• Late-Night Meals: Eating large meals within two hours of bedtime can cause discomfort and disrupt sleep onset.
• Stimulants: Caffeine, certain medications, recreational drugs, and even sugar consumption close to bedtime can prevent sleep.
• Environmental Factors: External disturbances like noise or too much light in the bedroom can interfere with quality rest.
