Did you know that not getting enough sleep is not healthy for your brain? New research shows that sleeping less than seven or eight hours a night has been linked to cognitive decline, memory loss, and possibly even Alzheimer's disease.
A sleep deficit can have dangerous implications for your brain, and not just because it makes you sleepy during the day. Parts of your brain are several times more active at night than during the daytime. One of them is a newly discovered drainage system called the glymphatic system. This is a bit like your city's sewage and recycling system. Its job is to clear out and recycle all toxins in the brain. One protein actively recycled during sleep is amyloid plaque. This plaque is the hallmark of Alzheimer's. Alzheimer’s disease is caused by many factors, but one of these may also be sleep deprivation.
A University of Pennsylvania study found that extended wakefulness can injure neurons essential for alertness and cognition, and that the damage to these neurons might be permanent. Other studies have led scientists to conclude that chemicals secreted during the deeper stages of sleep are crucial for repairing the body, including the brain.
One of the chemicals involved in creating memories, acetylcholine, is also developed during sleep and dreaming. Brain cells that produce acetylcholine are destroyed in people who are developing Alzheimer’s disease. So, these people do not dream as much.
Relaxation and meditation or mindfulness has been found to be very beneficial to brain and body health. Deep relaxation and meditation, when practiced regularly not only relieve stress and anxiety but have been found to improve mood. Deep relaxation has many other potential benefits as well—it can decrease blood pressure, relieve pain, and improve your immune and cardiovascular systems
The brain requires substantial downtime to remain industrious and generate its most innovative ideas. According to Tim Kreider, of the New York Times, "Idleness is not just a vacation, an indulgence or a vice; it is as indispensable to the brain as vitamin D is to the body, and deprived of it we suffer a mental affliction as disfiguring as rickets,"
Let’s get a good nights sleep, remember to relax, and meditate. do it all for the health of our brains and become better thinkers in the process!

Benefits of a Study Group
A study group can be beneficial in many ways. Here are the most important benefits:
1. A support group can "pick you up" when you find that your motivation to study is slipping. The other group members can be a source of encouragement.
2. You may be reluctant to ask a question in class. You will find it easier to do so in a small study group.
3. You may become more committed to study because the group members are depending on your presentation and participation. You will not want to let them down.
4. Group members will listen and discuss information and concepts during the study sessions. These activities add a strong auditory dimension to your learning experience.
5. One or more group members are likely to understand something you do not. They may bring up ideas you never considered.
6. You can learn valuable new study habits from the other group members.
7. You can compare your class notes with those of the other group members to clarify your notes and fill in any gaps.
8. Teaching/explaining information and concepts to the other group members will help you reinforce your mastery of the information and concepts.
9. Let's face it - studying can sometimes be boring. Interacting with the other group members can make studying enjoyable.
Getting a Study Group Started
Study groups don't just happen. Here is what you should do to get a study group started:
1. Get to know your classmates by talking with them before class, during breaks, and after class. When selecting a classmate to join your study group, you should be able to answer YES for each of the following questions:
o Is this classmate motivated to do well?
o Does this classmate understand the subject matter?
o Is this classmate dependable?
o Would this classmate be tolerant of the ideas of others?
o Would you like to work with this classmate?
2. Invite enough of these classmates to work with you in a study group until you have formed a group of three to five. A larger group may allow some members to avoid responsibility, may lead to cliques, and may make group management more of an issue than learning.
3. Decide how often and for how long you will meet. Meeting two or three times a week is probably best. If you plan a long study session, make sure you include time for breaks. A study session of about 60 to 90 minutes is usually best.
4. Decide where you will meet. Select a meeting place that is available and is free from distractions. An empty classroom or a group study room in the library are possibilities. AP DIGEST An Advanced Placement Program Student Resource Advanced Academic Services Austin Independent School District
5. Decide on the goals of the study group. Goals can include comparing and updating notes, discussing readings, and preparing for exams.
6. Decide who the leader will be for the first study session. Also decide whether it will be the same person each session or whether there will be a rotating leader. The leader of a study session should be responsible for meeting the goals of that study session.
7. Clearly decide the agenda for the first study session and the responsibilities of each group member for that session.
8. Develop a list of all group members that includes their names, telephone numbers, and email addresses. Make sure each group member has this list and update the list as needed.
Characteristics of a Successful Study Group
Once started, a study group should possess the following characteristics to be successful:
1. Each group member contributes to discussions.
2. Group members actively listen to each other without interrupting. Only one group member speaks at a time.
3. The other group members work collaboratively to resolve any concern raised by a group member.
4. Group members are prompt and come prepared to work.
5. The group stays on task with respect to its agenda.
6. Group members show respect for each other.
7. Group members feel free to criticize each other but keep their criticisms constructive. This can encourage group members to reveal their weaknesses so that they can strengthen them.
8. Group members feel free to ask questions of each other.
9. At the end of each study session, an agenda including specific group member responsibilities is prepared for the next session.
10. Above all, the positive attitude that "we can do this together" is maintained.
Possible Pitfalls of a Study Group
A study group can be a very positive learning experience. However, there are pitfalls to be avoided. Here are some cautions:
1. Do not let the study group get distracted from its agenda and goals.
2. Do not let the study group become a social group. You can always socialize at other times.
3. Do not allow group members to attend unprepared. To stay in the group, members should be required to do their fair share.
4. Do not let the session become a negative forum for complaining about teachers and courses.
5. Do not allow one or two group members to dominate the group. It is important that all members have an equal opportunity to participate. The information you just read will help you decide when a study group is appropriate for you and will help ensure its success.

Are you eating the right foods to feed your brain? Brain health is very dependent on a healthy diet. This is true for growing kids and aging adults as well. The brain represents about 2% of an adult’s weight, but it uses 20% of the energy produced by the body. If the energy supply is not adequate to fuel this energy, people may experience a variety of symptoms, including memory or concentration loss, and fatigue.
An appropriate diet is especially important for the brain health of adolescents. During teenage years, the body and the brain undergo many physical changes. What kind of food a teen eats, how much they eat, and when they eat can affect a teen’ attention span, the ability to focus, and memory capabilities. This translates into how well a student learns and performs in school.
Doctors are finding that what's good for the heart may also be good for the brain. Protecting the blood vessels by following a heart-healthy diet also protects the brain. Many of the same cardiovascular risk factors have been shown to be risk factors for dementia and Alzheimer’s disease. Eating a heart-healthy diet that is low in saturated fat not only reduces the risk for high blood pressure, diabetes, and obesity, but also can also protect your brain cells and prevent memory loss. Eating high-quality foods that are rich in vitamins, minerals, and antioxidants nourishes the brain and protects it from oxidative stress.
What types of foods feed our brain the best? Below is a suggested list of brain healthy foods:
This is a healthy source of fat in the diet and can help reduce cholesterol levels and blood pressure. Some studies have linked olive oil with a lower risk of ischemic stroke, cognitive impairment, and Alzheimer’s disease.
such as salmon, herring, and mackerel: This is an excellent source of omega-3, which your brain needs to stay healthy.
such as strawberries, blueberries, blackberries, spinach, beetroot, and beans: These foods are high in antioxidants, which help guard against disease by protecting cells in the body and brain from damage.
Foods containing polyunsaturated fatty acids like nuts, seeds, fish, leafy green vegetables, and monounsaturated fatty acids found in avocados and nuts may reduce your risk of both depression and dementia.
It contains high levels of antioxidants, although it is also high in sugar and fat. One small piece of dark chocolate per day is enough to get the antioxidant benefit. Green tea is another source of antioxidants.
By the same token, there are foods we should avoid for good brain health. Salty foods, sugary foods and drinks, processed foods, and foods containing trans fats are all bad for our body and our brain health. Let’s all eat a more healthy diet, it’s more than food for thought!

We all know that exercise is good for our bodies. But, did you know that exercise is also beneficial for your brain? Physical aerobic exercise increases blood flow throughout the body including the brain. As a result, brain cells are better connected and memory and thinking skills improve.
In a study conducted at the University of British Columbia researchers discovered that regular exercise, rigorous enough to increase the heart rate, appears to boost the hippocampus in the brain. This area of the brain is where verbal memory and learning takes place.
Other studies have proven that those who exercise are more mentally sharp. These studies have found that students score higher on math and reading comprehension tests after exercising for 20 minutes. Some studies have found that kids who exercise are happier and have a better positive outlook. This is because physical activity releases chemicals in the brain that are natural stress combatants. Thus, physically active kids are better at handling mood swings and their emotions.
In a recent online article published by the British Journal of Sports Medicine, a panel of experts from the UK, Scandinavia, and North America all agreed that regular physical activity can strengthen brain cells, create more neurons in the brain, and prevent brain tissue loss in older adults. Further studies have concluded that a daily schedule with more physical activity resulted in students achieving more and having better grades in the classroom. So, let’s join our kids and increase our physical exercise--it can benefit us all!
