Stress and Anxiety

High levels of stress and anxiety can lead to racing thoughts and difficulty relaxing, making it hard to fall asleep and stay asleep.

Lifestyle Factors

Irregular Sleep Schedule: Inconsistent bedtimes and wake-up times can disrupt the body’s internal clock.

Diet and Caffeine Intake: Consuming caffeine or heavy meals close to bedtime can interfere with sleep.

Lack of Physical Activity: Regular exercise promotes better sleep, while a sedentary lifestyle can contribute to sleep problems.

Environmental Factors

Noise: Loud or unexpected noises can disturb sleep.

Light: Excessive light, especially from screens, can interfere with the production of melatonin, a hormone that regulates sleep.

Temperature: An environment that is too hot or too cold can make it difficult to sleep comfortably.

Medical Conditions

Sleep Disorders: Conditions like insomnia, sleep apnoea, and restless legs syndrome directly impact sleep quality.

Chronic Illnesses: Diseases such as asthma, arthritis, and heart disease can cause discomfort or symptoms that disrupt sleep.

Mental Health Disorders: Depression and anxiety can both cause and result from poor sleep.


Some medications have side effects that include insomnia or disrupted sleep patterns. These can include certain antidepressants, antihypertensives, and medications for asthma.

Substance Use

Alcohol: While it may initially make you feel sleepy, alcohol can disrupt sleep later in the night.

Nicotine: Nicotine is a stimulant and can cause sleep disturbances.
