Smoking not only make people less sleep, but also responsible for change pattern of sleep that makes sleep was not soundly. Smoking can disrupt sleep by various means.

The most dramatic effect from the smoking is a reduction in time spent sleeping in, that is known to create a fresh feeling when you wake up in the morning.

In 2008, the journal Chest reported that chronic smokers spend more time on mild sleep (don’t sleep soundly), especially in the early evening, as reported by Livestrong, as follows:

Culprit is nicotine, that has a stimulating effect on the nervous system. Ironically, because nicotine in the blood flow is reduced during the night, increasing the withdrawal symptoms. Symptoms include anxiety and insomnia (difficulty sleeping).

Smoking is also a risk factor for sleep disorders known as dangerous obstructive sleep apnea (OSA). According to the Mayo Clinic, smokers are three times more likely to suffer from OSA than those who never smoked.

During the OSA, the airway will narrow or blocked, preventing enough oxygen from reaching the brain during sleep. Snoring is very loud and woke up gasping are 2 common symptoms of OSA, that if left untreated can lead to pulmonary hypertension, heart failure and premature death.

Smoking increases the risk for OSA because it irritates the throat habits and causes blockage in the evening. The good news, quit smoking immediately to improve sleep hygiene.
