This week for my curiosity blog post, I decided to challenge myself to do three curiosity topics. These three topics are based on education, Psychology, and Social media. Feel free to comment and ask any questions!
Education: How have modern technologies changed the way of teaching?
Psychology: Is stress really harmful?
Feeling stressed can be perfectly normal, especially during times like exams. You might find that being stressed can motivate you to focus on your work, but then again, at other times you feel overwhelmed and can't focus on anything. While stress affects everyone in different ways, there are two major types of stress: Stress that's beneficial and motivating- good stress- and stress that causes anxiety and even health problems-bad stress. According to experts, stress is a burst of energy that basically advises you on what to do. Stress can have many advantages. For instance, stress can help you meet daily challenges and motivates you to reach your goals. In fact, stress can help you achieve goals more efficiently. It can even boost your memory. Stress is also a vital warning system, producing the fight-or-flight response. When the brain perceives some kind of stress, it starts flooding the body with chemicals like epinephrine, norepinephrine and, cortisol. This creates a variety of reactions such as an increase in blood pressure and heart rate. Additionally, the senses suddenly have a laser-like focus so you can avoid physically stressful situations such as jumping away from a moving car- and be safe. Stress can improve how your heart works and protect your body from infection. In one study, individuals who experienced moderate levels of stress before surgery were able to recover faster than others who had low or high levels. Stress is key for survival, but too much stress can be detrimental. Emotional stress that stays around for weeks or months can weaken the immune system and can cause high blood pressure, fatigue, depression, anxiety and, even heart disease. In particular, too much epinephrine can be harmful to your heart. It can change the arteries and how their cells are able to regenerate. Stress is an inevitable part of life, but you can improve the way you respond to stress and avoid or change some of the situations that create negative stress.
Social media: Can the use of social media, lower teens self-esteem?
