Your brain senses these anxious feelings that you take to bed with you, it activates the stress response and causes adrenaline to be released into your system, which prevents your natural sleep cycle from working effectively. The stress response and the sleep response are opposite reactions in the body. Lifestyle habits are important factors affecting sleep quality, and the use of caffeine and nicotine are two major culprits that disrupt sleep. They act as stimulants increasing production of hormones to raise blood pressure, speed up the heart rate and stimulate brain-activity. Nicotine has a similar affect on the body as caffeine.
Smokers have difficulty falling asleep, and also staying asleep.
They tend to wake up at night craving a smoke, so their sleep is often fragmented. Insomnia ranks near the top of smokers' complaints. Sleep loss can affect your job. Researchers investigating the effects of lost sleep on workers' performance found that often problem-solving skills are impaired, communication skills suffer, learning and memory suffer, and motor skills are impaired.
