Sleep is a fundamental biological process essential for physical and mental restoration. Adults generally need 7-9 hours of quality sleep per night.
Poor sleep affects mood, concentration, immunity, and increases the risk of chronic conditions like hypertension, obesity, diabetes, and depression.
Common sleep disorders include insomnia, sleep apnea, and restless legs syndrome. Symptoms may involve difficulty falling asleep, frequent awakenings, loud snoring, or excessive daytime sleepiness.
