Sleep disorders are conditions that disrupt normal sleep patterns, affecting both the quality and quantity of rest. Common types include insomnia, sleep apnea, restless legs syndrome, and narcolepsy. Symptoms may include difficulty falling or staying asleep, excessive daytime sleepiness, loud snoring, or irregular sleep-wake cycles. Sleep disorders can result from stress, lifestyle habits, medical conditions, or hormonal imbalances and can impact physical health, mental well-being, and daily functioning. Effective management involves identifying the underlying cause, adopting healthy sleep habits, lifestyle modifications, and, in some cases, medical treatments or therapy.
