Instead of doing crazy diets, stick to something you can maintain for years to come—especially since, according to past research, constantly losing and gaining weight post-menopause could increase your risk of both sudden cardiac arrest and coronary heart disease. The instance was actually found to be strongest in women of a normal BMI

If you're thinking about becoming pregnant, it's a good idea to be aware of its effects on your heart. According to the American College of Obstetricians and Gynecologists, having high blood pressure during those nine months can put a lot of stress on the organ, which can in turn increase your risk of heart disease.

As if battling depression isn't already hard enough, Johns Hopkins Medicine says those with the disorder develop heart disease more quickly than the rest of the population. Since depression is more common in women than men, it's important to focus on your mental health now: for your overall happiness and well-being, but also for your body

Not many people realize it, but women's hearts are actually smaller than men's—two-thirds the size, in fact. Because of that, your heart rate is faster and you have smaller arteries, which can make it easier for them to be blocked up by plaque and cause health issues.

On average, your body uses around 1,500 calories a day in a resting state. And your brain consumes about 20 percent of those. That's roughly 300 calories a day and about 12 calories every minute!

In fact, it's the fattiest organ in your body. Fatty acids are crucial to your brain's health and performance, and a healthy diet is the best source of the essential fatty acids your brain needs.

So if your brain is 3 pounds, over two of those pounds of are water weight. Water is essential for delivering nutrients and removing toxins within the brain. It also acts as a shock absorber for both the brain and the spinal cord.

That's about 2 percent of your total body weight. Men tend to have larger brains than women, but in general, brain size doesn't translate to intelligence. And for additional information on health and more, sign up for our daily newsletter.

Your brain gets top priority when it comes to blood distribution within the body. That's because without a steady supply of oxygen-rich blood, brain cells will begin to die after as little as one minute. And speaking of oxygen, check out 17 Warning Signs Your Lungs Are Trying to Send You.

Together, the brain and spinal cord make up our central nervous system. The brain operates as command central, sending signals through the spinal cord to enable body functions like muscle movement and breathing. The spinal cord, meanwhile, transmits sensory information from the body back to the brain.

Chemical messengers called neurotransmitters are responsible for carrying that information across our bodies through neurons. Right now, billions of neurons are traveling at 120 meters per second (about 268 mph) to keep your brain functioning. And for more incredible information, check out 33 Amazing Things You Didn't Know About Your Own Body.

That's roughly half the number of stars in our galaxy. Neurons, also known as nerve cells, are responsible for sending and receiving signals from the brain. And for ways you can keep your mind sharp, check out 15 Brain Games That Will Make You a Smarter Person.

Your brain can generate enough electricity to power some light bulbs, according to the experts at Foglets. But charging your iPhone would take about 6,833 hours, which is 285 days. The energy is produced when glucose and oxygen are combined within tiny cellular power plants called mitochondria.

Human brains can compute about 1018 operations per second. How fast is that? About a billion billion calculations every second, according to scientific discoveries and innovations site Foglets. While computers use binary coding (i.e., alternating ones and zeros) to make sense of the world, human brains use 26 types of codes. They can also store an astronomical one petabyte of data.
