Smoking
Here’s another reason to quit smoking: better sleep. Smoking tobacco has been found to disrupt your natural circadian rhythms within the brain and lungs. Because of this, your quality of sleep worsens over time.
Any substance that contains nicotine, however, can induce insomnia. Nicotine stimulates the system, and the more you digest, the more difficult it will be to close your eyes. Although reducing your nicotine intake can be a challenge, it will certainly help with insomnia.
