A particular neuronal circuit between the two regions of the brain: the amygdala and the prefrontal cortex, is found to be responsible for alerting us when a particular threat has been eliminated.
The many neurological circuits between these two areas of the brain are the reason we experience and are able to regulate our fear response.
Decades ago, scientists noticed neurons increase their activity when an individual is taking a particular action, for example, waving when others are waving. They named them "mirror neurons."
But, your brain is really predicting your next action based on what you see, hear, and feel if you move. Seeing someone wriggle their fingers in the air and understanding it as a greeting is a normal part of your brain's predictive processes.
During any day, it can seem like your brain is reacting to events around you. You're pricked by a needle and feel a bit of pain.
However, your brain constantly predicts the next moment and compares the guess to the data it receives from the world and inside your body. These predictions turn into your actions.
You may have heard that your passions lie deep in ancient parts of your brain that you apparently inherited from prehistoric reptiles. Or that your "rational brain" which sits on top of your "lizard brain" tries to moderate your desires.
The only animal with a lizard brain is a lizard. Neuroscience clearly shows that brains don't evolve in layers but follow a single manufacturing plan.
Your brain doesn't store memories like a filing system. Your brain reconstructs your memories on demand with electricity and chemicals.
"Remembering" is really "assembling" and may be influenced by your current situation, so your brain may reshape each occurrence so that it differs in the details.
Most parts of the human brain can't grow new brain cells, but some parts can.
The hippocampus can grow new neurons. The hippocampus is important for learning, remembering, regulating your eating, and other biological functions.
All of your sensations are computed in your brain.
Generally, no part of your brain is exclusively dedicated to creativity or mathematical reasoning. Neurons compute every action you take from across the entire brain.
While your cerebral cortex consists of two halves, both are intricately connected. Language ability does take place mainly in the left hemisphere, but this lateralisation develops gradually in most people.
Hormones don't just have one specific psychological purpose, and all the chemicals work together in your mind.
Snacks can be seen as fuel that helps to keep your energy up until mealtime.
Snacks keep us over till the next meal. Balanced snacks and meals at consistent times during the day keep your blood sugar stable and keep you from overeating.
Healthy snacking include protein, fibre, and other nutrients that will keep your blood sugar in an optimal range. In contrast, low blood sugar causes exhaustion and makes you crave sugary or fatty foods.
Establish a regular eating schedule and stay with it. For example, breakfast at 8 a.m., lunch at noon, a snack around 3 p.m. and dinner at 6 p.m.
The biggest health benefit to eating at regular times is appetite regulation. Your body will adjust to the pattern within a week and you will become hungry at expected times. It will help you to recognise when you are really hungry or just desire to eat because of boredom or stress.
Eating three meals doesn't work for everyone. Some people like to graze. They may crunch on veggies and dip, potato chips, cheese with cracker, chips and salsa, or rice crackers and hummus.
A snack should match your nutritional need. Higher-calorie snacks give energy, while lower-calorie choices with more fibre and protein help to feel full and satisfied.
If you want to eat some snacks right now, consider if you're just thirsty. It is not uncommon to confuse hunger with thirst.
Reach for a glass of water or a can of seltzer before grabbing a snack. You may discover that you were not really hungry.
Parents can provide six meal opportunities: three meals, with two to three snacks.
Kids that graze all day may not learn to listen to their hunger and fullness signals. However, with designated snack time, kids are often more willing to eat what they need or stick with healthier options.
We all need food to generate energy. Our body uses hormones that circulate in the blood to control our food intake.
Hormone levels change when we lose weight and are also the reason why most of us will regain the weight we lose.
Studies found that diet-induced weight loss is associated with hormone changes that promote weight gain.
After weight loss, leptin levels will decrease. But ghrelin, GIP and pancreatic polypeptide will increase in circulation while PYY and CCK will lower. Most of these changes favour regaining lost weight. These hormonal changes seem to be present for at least one year after weight loss, leading to a constant increase in hunger.
The hypothalamus coordinates the body's system that regulates food intake.
Whether you feel like eating depends on the balance of the activity between these two sets of neurons.
A high fasting blood sugar level can indicate Type 2 diabetes or pre-diabetes. People with diabetes are four times more likely to die from heart disease.
An A1C test indicates your average blood sugar levels over time. It measures the amount of glycated hemoglobin in your blood, which shows your average blood sugar levels over the past three months.
Heart disease and strokes are the number one cause of death worldwide. However, almost 80 percent of all cases of cardiovascular disease is preventable.
Making some changes to your lifestyle can lower the risk of heart disease.
Aside from a medical issue, you can do two things to improve your blood sugar control: exercise and eating smart.
Things that can contribute to chronically high blood sugar or throw off a test are:
Many foods can improve your cholesterol levels. They include:
Cholesterol plays a big role in heart disease. The heart association recommends getting your cholesterol levels measured every four to six years.
Research has shown that even a few minutes of exercise leads to benefits.**It’s all about increasing the intensity.**
The ideal exercise for adults are :
For more intense workout sessions, you should aim for:
Smoking is the most common cause of heart disease. Smoking causes emphysema, cancer, gum disease, and harms almost every organ in your body. Tobacco smoke damages blood vessels, increases blood pressure, lowers HDL cholesterol, and causes peripheral artery disease and atherosclerosis.
Quitting will immediately lower your risk of a heart attack.
Exercise is the one thing that can improve nearly every aspect of your health.
Extensive studies have found that exercise enhances the cardiorespiratory system, increases HDL cholesterol, lowers triglycerides, reduces blood pressure and heart rate, lowers inflammation, and improves blood sugar control.
