When you quit smoking, your body begins healing almost immediately. Here's what happens at each milestone in your smoke-free journey.
The First Hour
20 minutes: Your heart rate and blood pressure drop back toward normal levels. The nicotine has already started leaving your system.
1 hour: Your circulation begins to improve. You might notice your hands and feet feeling warmer as blood flow returns to normal.
The First Day
8 hours: Carbon monoxide levels in your blood drop by half. Oxygen levels return to normal. Your body is already working hard to cleanse itself.
12 hours: Carbon monoxide is completely eliminated from your body. Your blood oxygen levels are now normal, making it easier to breathe and exercise.
24 hours: Your risk of heart attack begins to decrease. The toxins in cigarette smoke that stress your cardiovascular system are clearing.
The First Week
48 hours: Your nerve endings begin to regrow. Your senses of taste and smell start improving dramatically. Food tastes better!
