How are sleep quality and quality of sleep affected by smoking? Smoking has many effects on the human body that are linked to sleep problems such as: Smoking decreases blood circulation, decreasing blood pressure and increasing your risk of heart attack and stroke. Smoking makes the blood oxygen level in the blood fall and also makes you tired and sleepy. A better sleep has many things to do with it. Smoking affects the hormone called epinephrine and makes the heart rate go up. Epinephrine causes your heart to beat faster and your blood pressure to rise. If you are sleeping more, this increases your risk of having a heart attack or stroke. The number of days you have to stop smoking before the heart attack starts depends on your age and your heart condition. If you have the type of heart disease and the medication you are taking doesn't have enough epinephrine, the number of days you can stop smoking is shorter. It can be easier to smoke after taking some type of medication.
Sleeping is a big factor in the health of your heart. Smoking increases the amount of free radicals in your body that cause damage to your heart.
