What Causes Insomnia?
Insomnia can be caused by non-disease factors and disease factors. The former include environment and diet, while the latter encompass psychological disorders, physical illnesses, and adverse drug reactions.
Non-disease Factors
1. Environment: An overly noisy or brightly lit sleep environment can disrupt a person's ability to fall asleep, leading to insomnia.
2. Diet: Consuming coffee, strong tea, or spicy and stimulating foods before bedtime can increase neural excitability in the brain, causing symptoms of insomnia.
Disease Factors
1. Psychological Disorders: Conditions such as anxiety, depression, and phobias can cause chronic stress, leading to overstimulation of the sympathetic nervous system and keeping the cerebral cortex in an excited state, preventing deep sleep and thus causing insomnia.
2. Physical Illnesses: Chronic conditions like hypertension, diabetes, heart disease, or hyperthyroidism can stimulate the body during illness, causing discomfort and affecting normal sleep quality, thereby inducing insomnia.
3. Adverse Drug Reactions: Certain medications, including antidepressants, antipsychotics, and diuretics, may interfere with normal sleep patterns, leading to insomnia.
Apart from the aforementioned reasons, insomnia can also be associated with aging. It is recommended to maintain a positive mindset, avoid excessive fatigue, engage in regular physical exercise to boost immunity, and seek medical attention if necessary to prevent condition aggravation.
