Caffeine, Alcohol, Nicotine, and Medicines

Understand common substances that can alter sleep and why responses differ.

Caffeine can outlast the feeling of stimulation

Coffee, tea, energy drinks, cola, chocolate, and some medicines contain caffeine. People vary in how quickly they process it and how sensitive they are to it. If sleep is difficult, test a gradual reduction in afternoon and evening caffeine rather than assuming a late cup has no effect.

Alcohol is not a reliable sleep treatment

Alcohol may make a person feel drowsy at first, but it can disrupt sleep later in the night. Using it as a bedtime aid can create a cycle in which falling asleep seems easier while sleep quality and continuity are worse. Nicotine is stimulating and can also interfere with sleep.

Review medicines, do not abruptly stop them

Some prescription and over-the-counter medicines can influence alertness, sleep timing, or nighttime awakenings. Make a current list of prescriptions, nonprescription medicines, supplements, and the times you take them. Ask a prescriber or pharmacist whether any could affect sleep and whether timing can safely be adjusted.
