The benefits of a good night's sleep
The big test is in eight hours, then comes a piano recital, and it's four in the morning. Even after days of studying and playing, you still don't feel prepared for either. What can you do, then? You could have another cup of coffee, spend the next few hours studying and practicing, but, dare I say it, you might be better off finishing your work, putting your music away, and going to bed. Nearly a third of our lives are spent sleeping, yet many of us pay it surprisingly little attention and care. This omission frequently results from a serious misunderstanding. Sleep is neither wasted time or merely a way to unwind after finishing our most important tasks. Instead, it serves as an essential function that your body uses to balance and control all of its internal systems, including those that control development, immunity, and breathing. That's terrific, but after this test, you can worry about all those things, right? Well, not quite yet. As you fall off to sleep, a fifth of your body's blood flow is diverted to your brain, proving that sleep is essential for your brain as well. Additionally, your brain undergoes a time of very active reorganization when you sleep, which is essential for how our memories are organized.Our capacity for memory doesn't initially appear to be all that impressive. The forgetting curve, which Herman Ebbinghaus first described in the 19th century, is a phenomena whereby humans typically forget 40% of new information within the first 20 minutes. However, memory consolidation, the process by which information is transferred from our ephemeral short-term memory to our more resilient long-term memory, can stop this loss. The hippocampus, a significant portion of the brain, aids in this consolidation.Brenda Milner's research with patient H.M. in the 1950s proved its significance in the development of long-term memory. H.M.'s ability to create new short-term memories was impaired after having his hippocampus destroyed, but he was still able to perform physical activities through repetition. H.M.'s capacity to create long-term memories was similarly harmed by the loss of his hippocampus. The hippocampus was specifically involved in the consolidation of long-term declarative memory, such as the facts and concepts you need to remember for that test, as opposed to procedural memory, such as the finger movements you need to master for that recital, which was one thing that this case revealed, among other things.Our current understanding of how this consolidation process functions was developed using Milner's results as well as Eric Kandel's work from the 1990s. Initial transcription and short-term storage of sensory information takes place in the neurons. The neurons in that cortical area are strengthened and enhanced as it continues on to the hippocampus. New synaptic buds are created as a result of the neuroplasticity process, enabling new connections to form between neurons and strengthening the brain network where information is stored for long-term memory retrieval. Why then do we recall some things while forgetting others?Well, there are a few ways to affect how well and to what extent memories are retained. For instance, because the hippocampus and emotion are linked, memories that are created during periods of intense emotion or even stress will be better remembered. But as you would have anticipated, getting a good night's sleep is one of the main variables promoting memory consolidation. There are four stages of sleep, with slow-wave sleep and rapid eye movement being the deepest. Electrical impulses have been shown traveling between the brainstem, hippocampus, thalamus, and cortex, which act as relay stations for memory formation, on EEG devices watching humans during these stages.Additionally, it has been demonstrated that various sleep stages aid in the consolidation of various memory types. Declarative memory is encoded into a temporary store in the anterior region of the hippocampus during non-REM slow-wave sleep. It is then frequently reactivated by a continuous exchange between the cortex and hippocampus, causing it to gradually redistribute to long-term storage in the cortex. Contrarily, REM sleep, which resembles waking brain activity, is linked to the consolidation of procedural memory.According to the studies, the best time to go to bed is three hours after memorizing your formulas and one hour after practicing your scales. So hopefully it's clear that not getting enough sleep not only affects your long-term health but also decreases your ability to remember what you learned and practiced the night before, which only serves to prove the wisdom of the proverb "Sleep on it."You could even say that getting enough sleep will have you waking up every morning with a fresh and enhanced brain, prepared to meet the difficulties ahead, when you consider all the internal remodeling and building of new connections that occurs while you snooze.

How to STOP Waking Up Feeling TIRED Every Morning
How frequently do you genuinely feel invigorated when you wake up? How often a week do you wake up when your alarm goes off instead of using the snooze button? There is nothing worse than going to bed early and waking up yet feeling worn out. The amount of fatigue you experience in the morning depends on a variety of variables, and you undoubtedly have some bad habits that sap your vitality. We'll look at some of the strategies you should use to get a good night's sleep so that you can wake up early. Let's get going. 1. Quit sleeping You don't actually get more sleep when you snooze. You don't feel much better about waking up as a result. Actually, it offers you no advantages. You wake up more exhausted each time you use the snooze button. This is due to the 90-minute cycles that make up our sleep. Your alarm wakes you up in the middle of your sleep cycle when you snooze for such a brief period of time, making you feel even more exhausted and lethargic. My suggestion is to utilize the "Sleep Cycle" app. This app wakes you up at the conclusion of your sleep cycle. It does this by monitoring your movements throughout the night and only sounds the alarm when it realizes you have reached the end of the cycle. Compared to waking up in the middle of your REM period, this method of awakening will leave you feeling considerably more energised. 2. Get adequate rest Our bodies require a specific amount of sleep each day in order to function effectively. You probably already know this, but we frequently get either too little or too much sleep. This may sound silly. We have irregular bedtimes, which may be one of the causes of this. We go to bed at 10 p.m. one night and 3 a.m. the next.However, you should wake up and go to bed at the same hour every day of the week. By doing this, you train your body to wake up naturally at the end of each sleep cycle every day. Additionally, the quantity of sleep needed by each individual to feel energised varies. Put yourself to bed at the same time each night for a week to determine how many hours you personally require to wake up feeling rested. Without setting an alarm, get out of bed and jot down how long you slept each night. You should be able to determine how many hours you require to wake up and have a productive day by the end of the week. Then, you can use this knowledge to determine when you should go to bed and wake up. 3. Rehydrate and stimulate blood circulation You must hydrate yourself as soon as possible in the morning. You'll become naturally dehydrated after 6 to 8 hours without drinking, and dehydration makes you feel tired. I put a glass of water on my bedside every single day before I go to sleep. In this manner, the water will be ready for me when I awaken. To restore the water you lost while you were sleeping, the goal is to rehydrate your body and mind as quickly as possible.People frequently need more water, not more coffee, when they are feeling fatigued, whether it is in the morning or the afternoon. Light exercise right after you wake up is another crucial action to take. Your energy levels will increase with any physical activity that increases your heart rate and blood flow. Contrary to popular belief, regular exercise really helps your body produce energy rather than making you fatigued, according to studies. Even if you feel too exhausted to do anything, stand up and move around the room. After a few minutes, you'll notice that you have more energy than you did before.It is not necessary to perform an intense activity. There is no requirement to run a marathon before breakfast. What I often do is some stretching, followed by burpees and jumping jacks. 4. Avoid using screens before bed. Artificial blue light is produced by the screens on your computer, smart phone, and TV. Artificial light in the evening is problematic because it confuses your body into believing that it is daytime. Your body naturally creates melatonin, a sleep hormone, as the day grows darker outside. Since artificial light prevents the body from producing melatonin, it can seriously disrupt sleep because your body is unable to tell your cells that it is time for bed. You should avoid gazing at screens for at least two hours before night because of this. Because you need to get up early, if you're watching this video on your phone at 2am, well. Tomorrow you should put this advice into practice and perhaps swap your phone for a good book. There is a solution to the blue light issue for those of you who are unable to go without your phone or computer before night. Installing the Twilight and F.lux applications on your PC and phone is a good idea. What they do is make your screen more orange, which blocks the majority of artificial blue light. The nicest part is that neither is charged.However, you won't use any devices before night if you're committed to resolving your fatigue issue. I'm hoping today taught you something new. I've been using all of these suggestions for a while, and they really do help. Post your other tried-and-true remedies in the comments section below if you'd like to share them. Together, we can improve upon yesterday.

Can Exercise Actually "Boost" Your Metabolism?
We frequently hear that physical activity can help us lose weight by enhancing or accelerating our metabolism. Is it true, then? Can we regulate our metabolism through exercise? Dr. Jen Gunter's segment on "Body Stuff" We must first examine metabolism in greater detail before we can respond to that issue. It should come as no surprise that metabolism is incredibly complex and that scientists and researchers are always learning new things about it. Simply put, metabolism is the series of chemical processes that take place in each and every cell of our body to use energy to sustain life. Our bodies' processes of creating new cells, growing hair, and transforming food into energy all fall under the category of metabolism. Calories represent the entire amount of energy used by all of the metabolic activities that take place throughout our body. Surprisingly, only a small portion of the calories we burn each day come from exercise. Our basal metabolic rate, unless you're a professional athlete, accounts for the majority of our caloric consumption. Everything essential to our survival, such as our ability to blink, develop hair, and create new cells. That thing consumes a significant amount of our energy. Can we somehow manipulate this equation, then?Can we increase our metabolism through exercise to burn more calories? Can we calorie-burn even more? not only performing burpees but also increasing eyelash growth, as opposed to before? No, is the response. This is a misinterpretation of what fast versus slow metabolism actually means, to start. Neither a fast metabolism nor a slow metabolism are clearly associated with being slimmer or larger. In fact, if you look at the absolute figures, people with larger bodies have faster metabolisms, which means they burn more calories because they have more cells in their bodies, which are doing more to support the body. Although there are variances in metabolism among individuals with comparable body sizes, the gap between a fast metabolism and a slow metabolism can range from roughly 300 calories. That resembles a banana and two apples. Our metabolism's rate is largely genetically determined and influenced by our body size, but age also plays a role. Throughout our lifetime, our metabolic rate changes a few times. The infant's metabolic rate is where we begin. When we are toddlers, there is a switch, and it remains largely steady throughout adulthood until we reach the age of 60. A Tanzanian ethnic group known as the Hadza who still follow a traditional hunter-gatherer way of life was studied by researchers. However, when body size and age are taken into account, they burn about the same number of calories per day as the typical American adult. It appears that our bodies have limits and that the number of calories we expend is rather constant. Our metabolism will eventually find strategies to conserve energy even if we workout harder initially. Here is what I'm trying to say. Our metabolic system is designed to regulate energy, not to control our weight. As a result, whether you read an article or hear a self-proclaimed expert encourage you to speed up your metabolism, keep in mind that it's merely marketing jargon derived from a culture of weight reduction. And it's simply untrue.

What's normal anxiety
In our society, mental health problems are not treated seriously. A lot of stigma exists. Some others may advise you to "suck it up," "get it together," "stop worrying," or "it's all in your head." However, I'm here to assure you that anxiety disorders are a legitimate condition, just like diabetes. (Music) Dr. Jen Gunter's segment on "Body Stuff" Hello again. Dr. Jen here. I've noticed a trend among my patients. They frequently go over some of the typical signs of an anxiety condition with me. Constant anxiety, sleep issues, tense muscles, and difficulty concentrating.However, they are not receiving care. In this nation, there are numerous problems with mental health care. Some folks lack the necessary insurance to cover it. Some people don't think getting aid will benefit them because they have previously been reduced or disregarded. Some people are concerned with the stigma and whether it would influence potential careers or relationships. But having excessive anxiety is not a moral or character flaw. Like diabetes or strep throat, it is a health issue. It needs to be taken seriously in the same way. Let's first discuss anxiety itself before moving on to anxiety disorders. The very real and common emotion we experience in a difficult environment is anxiety. It has to do with fear.However, unlike anxiety, which is a response to less certain threats and typically lasts far longer, fear is a reaction to an immediate threat that swiftly passes. All of this is a part of the threat detection system that all animals possess to some extent in order to help defend us against predators. The brain's amygdala, a pair of almond-shaped nerve bundles that signal other brain regions to be prepared for protective action, is where anxiety begins. The signal is then passed on by the hypothalamus, which causes our body to go into what is known as the stress reaction. Our respiration and pulse rate quicken, our muscles strain, and our blood pressure rises.Your brain stem activates certain regions, putting you in a state of high attentiveness. This reaction is the fight-or-flight reaction. With the help of the ventromedial prefrontal cortex, a region of higher-level thinking, the fight-or-flight response can be kept somewhat under control. This is how it functions. The amygdala gets the message to run if a person encounters something they perceive as dangerous, like a tiger. Hey, look, the ventromedial prefrontal cortex can communicate with the amygdala. In a cage is the tiger. You are aware of what a cage is. A cage prevents them from escaping. It's okay to relax. It's a feedback loop that can aid in controlling the response. Hippocampus involvement is also seen. By mentioning something like, "Hey, we've seen tigers in cages before," it gives context. In a zoo we are. You are especially secure. These threat-detection systems, as well as the mechanisms that lessen or prevent them, malfunction when we experience anxiety, which makes us worry about the future and our safety in it. However, it goes into overdrive for a lot of folks. They have ongoing, all-pervasive anxiety that interferes with their relationships, employment, and education and causes them to avoid situations that can exacerbate their symptoms. Disorders of anxiety are very frequent. Researchers estimate that roughly 16 percent of people either presently have or have had an anxiety problem based on data from the World Mental Health Survey. These include phobias, agoraphobia, panic disorder, social anxiety disorder, and others. According to studies, those who suffer from anxiety disorders don't simply respond to stress in a different way. There might be genuine variances in the way each person's brain functions. The amygdala's connections to other areas of the brain may become confused, according to one hypothesis. Anxiety-related neural circuits get stronger. And the pathways get stronger the more anxious you are, creating a vicious cycle.The good news is that anxiety can be treated, so you don't have to endure it. Don't forget, this is not about being weak. It has to do with altering brain patterns, and studies have shown that this is something that is possible throughout life. Doing the fundamentals is a solid first step. Because your mind is an extension of your body, eat a balanced diet, exercise frequently, and get plenty of sleep. Try meditation; it might be beneficial. With mindfulness and breathing, we can reduce the fight-or-flight response and enhance how we feel right now instead of our heart rate increasing and our body tensing.Talk therapy in the form of cognitive behavioral therapy is also very good. It teaches you how to recognize distressing thoughts and evaluate their viability. Cognitive behavioral therapy can gradually restore the brain connections that control the anxiety response. Long-term and short-term relief are both possible with medication. Anti-anxiety medications have the short-term ability to slow down overactive threat detection processes.Studies have demonstrated that cognitive behavioral therapy and long-term medicines can both lessen the overactivity of the amygdala that we associate with anxiety disorders. Diabetes and high blood pressure are conditions that can be managed or treated over time. The same holds true for anxiety disorders as well.

Why you don't need 8 glasses of water a day
You are aware of the eight glasses of water a day recommendation? I regret having to inform you that it is a myth. It won't make your skin more radiant, you feel more clear-headed, or you feel more energised. However, it might cause you to urinate frequently. Body Stuff with Dr. Jen Gunter (music) (Music) Many people are unaware of how their bodies work biologically. There is a ton of false information available. However, the reality is that you may make wiser decisions when you are aware of how your systems work. You're less likely to believe hype or dubious science.You'll feel more capable of comprehending what's actually happening. The misconception that you need eight glasses of water a day truly irritates me. Really, it's quite astounding how deeply ingrained it is. You see it in articles and hear it on television. But like I stated, it is absurd. Generally speaking, your body will let you know when you need to drink water since you have kidneys, which are beautiful, magnificent, and underappreciated organs. The bean-shaped organs known as kidneys are situated on either side of your spine, just below your ribs. The kidneys deserve better than to be viewed as a filter or a system for getting rid of waste. Everything in your body, including the fluids and chemicals, must be in a precise balance. When it comes to maintaining this balance, the kidneys do most of the work. Your body's blood flows through the kidneys on a daily basis. Your body's state is influenced by a variety of factors, including what you eat and drink, the environment's temperature, and how much exercise you get. Your nervous system, numerous hormones, and your kidneys are constantly monitoring gauges and making real-time adjustments to fluid, salt, and other material levels. Nephrons, which are a million in number, are used to do this. To ensure that the body maintains homeostasis, or balance, these nephrons act much like employees on a conveyor belt, actively adding and removing substances like sodium, glucose or sugar, calcium, amino acids, and water. Anytime any quantity is out of balance, it might be dangerous. The kidneys' function is to keep the amounts of several of these compounds in the ideal range. Unneeded substances leave the kidney and travel to the bladder, where you eliminate them as urine. So how does drinking eight glasses of water each day fit in? Not at all. You'll note that I did not say that drinking too much water enhances renal function. Consider that you are losing water from your blood because you are perspiring a lot. Your kidneys are aware of a very little decrease in blood volume and a very slight increase in blood saltiness. They make up for it by reabsorbing more water into the blood, which increases the concentration of the urine. You are alerted to drink, i.e., you become thirsty, if the kidneys determine that sufficient amounts of fluid cannot be reabsorbed from the urine. The message of thirst intensifies if you don't have access to fluids. Real dehydration will not leave a person uncertain of their need for water. They'll take any measure necessary to obtain it.One of our most fundamental impulses, it developed over a very long time in situations when clean water wasn't quite as accessible as it is now. Your body is therefore very adept at keeping hydration thanks to your kidneys. How much water should you be drinking if you stop counting the eight glasses you should drink each day? There is no should, is the straightforward reply. Whenever you get thirst, sip some water. Your body can be trusted. Constantly tracking how much water you consume is not really important unless you have kidney stones, are senior -- occasionally, our messaging systems get a little worn with age -- or your doctor has advised you otherwise.One thing that is sometimes forgotten is that everything you eat contains water. Your breakfast has water, as does your morning coffee. And just like you, that snack—an apple, an orange, a glass of juice, a granola bar—is formed of water. There is therefore no need to count those eight glasses as long as you pay attention to your body's innate thirst signals.
