These 6 Body Parts You Can Repair Yourself

Your Brain
The damage: You scorched your gray matter in ways you can’t even remember.

The natural defense: For years, it was thought that we stopped making fresh neurons in puberty, meaning that sometime in high school a long die-off of brain cells commenced. Turns out it only seems that way. “The brain is just another organ,” says Fred H. Gage, Ph.D., a professor in the laboratory of genetics at the Salk Institute and the first researcher to demonstrate new neuronal growth in mammals. “The brain is attempting to fix itself, just as skin tries to heal itself after a nick or cut.” exercise, weight loss, diet, alternative medicine, weird, amazing, list worthy

What you can do: Work your body. Animal studies have shown that exercise can induce neurogenesis (the formation of new neurons) in two key areas of the brain: the hypothalamus, which helps form new memories and learning; and the olfactory bulb, where your sense of smell is located. The studies were done on rats, but what’s good for a rodent should be good for your brain: Try to get at least 30 minutes of exercise 2 or 3 days a week. exercise, weight loss, diet, alternative medicine, weird, amazing, list worthy

Your Lungs
The damage: Bad air, from smoke or smog, has clogged your air-exchange system.

The natural defense: The lungs come equipped with a self-cleaning cycle, but overloading them with smoke or smog will gunk up the works. The cilia, or hairlike structures in your lungs, flagellate (that’s move) upward, coaxing the bad stuff out of the alveoli (little air sacs) and into the trachea, where the gunk grows into a frightening reminder of why you should have been better to your lungs to begin with. “It’s like a mucus escalator,” says Norman Edelman, M.D., a scientific advisor to the American Lung Association. “That’s a major form of defense. Within a few days to a week (after quitting smoking], you start feeling better, and you start coughing up all that bad mucus you have down there.” exercise, weight loss, diet, alternative medicine, weird, amazing, list worthy

What you can do: Exercise will help loosen the large chunks after you first come clean. But you should be exercising already. Retinoic acid, or vitamin A, could actually help your lungs rebuild. Rats and mice with emphysema (they smoked tiny little cigarettes) given the compound were able to restore alveoli, which swap carbon dioxide for fresh oxygen to pre-emphysema levels, according to a recent study published in the European Respiration Journal. You’ll get several times the recommended daily allowance (900 micrograms) in only one serving of carrots, sweet potatoes, or mango. exercise, weight loss, diet, alternative medicine, weird, amazing, list worthy
