Several substances can make it more difficult to sleep. Caffeine is a popular stimulant found in many soft drinks and coffee products. Excessive amounts of caffeine can lead to insomnia. Harmful carcinogens like nicotine can also make sleeping more difficult, on top of the interference of limited blood supply caused by sleep apnea that could result from a history of smoking.

Sleep apnea is the primary health condition linked to insomnia, since it can directly discourage a person from continuing to sleep. Lifestyle factors come into play as well, such as late night shift work and specific stimulants.
