Your body when you Swim

Harvard medical school published a study which looked at over 40,000 men, aged 20-90 who were either runners, walkers, swimmers, and physically in active people. With an average length of 13 years of observation and in that time

  • 2% of swimmers passed away
  • 8% of runners passed away
  • 9% of walkers passed away
  • 11% of physically inactive people passed away

This study showed that swimmers are much healthier later on in life than the rest of the population and for women swimming just 30 mins a day can decrease coronary heart disease by 30 to 40 percent.

It also helps to increase HDL aka good Colestrol. Some studies have also shown that aerobic excercise can keep the cells in the lining of your arteries more flexible and healthier. Hence there is no question that swimming is an awesome form of fitness.

Body during swimming

What do you actually feel when you go into the water? Here are some main elements of the human body that gets impacted during swimming.

1. Blood

According to the America Heart Association, swimming is considered as Aerobic activity. Aerobic excercise enlarges the heart and it increases the blood flow through the entire boby. Because swimming is an excercise, the blood has to pump all the molecules into the body.

2. Heart

Since so much of blood has to be pumped into the body, that ties into how it impacts your heart because we know that after 2 mins your body goes into aerobic respiratory because your heart has to pump all the oxygenated blood through the body. So as you swim, your heart is circulating the blood which help your body to perform and achieve the required goals.

3. Skin

You must have seen that the skin color changes of swimmers. For example, some swimmers face turns red when the swim, that happens because your blood vessels are dilating and the brings the heat to the surface into the skin then some people turn red, as a result your skin is showing the effort that you’re putting in the water.

4.Muscles

There’s a reason why swimmers are considered to have best body and physiques in the world compared to any athlete, because swimming engages every single muscles in the water when it comes to your core stability, your upper body, your biceps, your hamstrings, your calves, everything is engaged when you swim.

When you’re swimming, you are micro tearing your muscles while swinging it. And the muscles requires 24-48 hrs to recover those muscles. That’s when sometimes you might feel sore.

5. Lungs

Swimming can actually help increase your lungs volume because in swimming different than other sports, you can’t actually breath whenever you want. It’s not like running when you have full access to oxygen.

In swimming you’re engaging your muscles and you’re not allowed to breathe necessarily at the time when your body might want it. So because you have to get used to this, you actually increase your Vo to max (maximum amount of oxygen body is able to use). So basically you are making your lungs more efficient at functioning.

6. Brain

The Brain loves swimming, because of all the extra blood flow moving through these endorphins that makes you more awake, alert and focus.

But this could happen in any type of sport but swimming is something really special because you’re sort of in your own world where the medium is 800 times more dense than air, which makes you feel free and relaxed.

Hence, from physical health to mental health, swimming is an incredible benefit human body and after reading this you must be thinking of trying swimming.

Music can change you

These days we hear music all the time, it wakes us up, motivates our workouts, keeps us company on our commutes. It doesn’t matter what kind of music it is, it itself has the ability to affect our moods and our bodies in all sorts of ways. It can give us chills even can make us cry.

Effects on Brain

Music activates every area of the brain that scientists have mapped so far. In fact, there is no area of the brain that music doesn’t touching some ways.

25 years ago there was an idea which said that language is in left side of the brain and music is in right side of the brain but now with better quality tools, higher resolution, neuroimaging and better experimental methods, it is discovered that thats not at all right so how does it effects our brain?

When music enters and then gets shuttled off to different parts of the brain:-

  1. It stops at specialise processing units in auditory cortex, they track loudness, pitch, rhythm, etc.
  2. The visual cortex activates when you’re reading notes as a musician or watching music.
  3. Motor cortex activates when you move or dance or tap your feet, snap fingers, clapping your hands.
  4. The Cerebellum activates and immediate the emotional responses.
  5. The memory system in the Hippocampus will activate and will help you to recognise any familiar music or lines that you listen

Hence, music is going on in both halves of the brain, left and right, the front, back, the inside, and the outside.

How playing Instruments helps?

We can start learning to play instrument at any age. Picking up an instrument can provide some huge benefits for Intelligence, Physical well-being, Brain.

Playing an instrument requires:-

  • Auditory motor
  • Sensory
  • Visual system to work together

This inner system cooperation has some incredible outcomes that can affect many areas of life.

Different intensities of training produce different outcomes, even the most minimal practice can make a difference. Starting to play an instrument just one hour a week for few months can cause growth and increased activity in the parts of the brain responsible for memory, hearing, and motor. Researchers have found that this kind of activities can even increase IQ by 7 point or more.

Its also known that people who play musical instrument are better at other practical things too such as:-

  • Practical emotions
  • Learning new things/tasks
  • Creative problem solving

Musicians brain have better communication between left and right hemisphere which allows for more cooperation and out of the box thinking. Playing an instrument can also has benefits for brain and body.

  • boosting immune system function
  • Increase in resilience to hearing lose
  • Helps stroke patients regain motor skills

It’s been found that just listening to music can prompt the repair and regeneration of damage nerves in the brain.

Music is so much more than notes on a page, it can change the way we think, speak and feel. Music making and listen is really complex it’s not demystified till now it’s more mysterious than ever.

How food affects our Brain?

How food affects our Brain?

Relationship of food with human brain and body

Other than water, our brain consists of fats or lipids, proteins, amino acids, micronutrients and glucose. Each of these components has a distinct impact on the functioning and development of the brain, our mood and energy.

Out of the fats in our brain, the most essential are omega 3 and omega 6. These fatty acids have been linked to preventing degenerative brain conditions and must come from our diets. Omega rich food like nuts, seeds and fatty fish are also crucial for development of cell membranes. While omegas are good fats for the brain overconsumption of other fats like trans fats and saturated fats may compromise mental health.

Proteins and amino acids are the building block nutrients of growth and development. They can affect the way we feel. Amino acids contain precursors of neurotransmitters, the chemical messengers that carry signals between neurons, affecting things like mood, sleep, attentiveness and weight.

The complex combinations of compounds in food can stimulate brain cells to release mood altering chemicals like dopamine, serotonin and norepinephrine. A diet with a range of foods help maintain a balanced combination of brain messengers, and helps keep our mood getting skewed in one direction or the other.

Like other organs of the human body, our brain also benefits from a steady consumption of micronutrients. Antioxidants in fruits and vegetables provide the necessary strength to our brain to fight the free radicals which destroy brain cells and enable it to work better for a longer period of time. Powerful micronutrients like vitamin B6, B12 and folic acid help prevent brain disease and mental decline. Trace amounts of minerals like iron, copper, zinc and sodium are fundamental to brain health and early cognitive development.

Our brain needs a lot of fuel to synthesize these nutrients. While the human brain makes up about 2 per cent of our body weight, it uses up to 20 per cent of our resources. Most of the energy comes from carbohydrates consumed as food that our body digests into glucose. A change in mental function may be the first signal of glucose deficiency in the body as the frontal lobes are sensitive to drops in glucose.

Carbohydrates enter the body in three forms i.e., starch, sugar and glucose. The ratio of sugar and fiber affect how the brain and body respond. High glycemic food like white bread may shoot up the blood sugar levels suddenly and then with the consecutive dip our attention and mood also lowers down whereas oats, grains and legumes have slower glucose release which enables a steady level of attentiveness.

Whatever we eat has a direct and often long lasting effect on our brain. Thus its important to choose a diet rich in varied nutrients for sustained brain power.

Dementia

Dementia is a progressive and sometimes chronic brain condition that causes problems with person’s thinking, behaviour, and memory.

Dementia itself is not a disease, but a syndrome, its symptoms are common to several brain diseases. It worsens over time. But medications might slow that decline and help with symptoms, such as behaviour changes. There are many different types of dementia. The treatments depend on the type of dementia.

Alzheimer’s Disease-Experts think between 60%-80% of people with dementia have this disease. It’s what most people think of when they hear “dementia”. Symptoms such as memory loss and trouble planning and doing familiar tasks.

Symptoms – mild at first but get worse over a number of years,confused about where he/she is or what day or year it is, Have problems speaking or writing, lose things and be unable to backtrack to find them, show poor judgement, have mood and personality changes

Vascular Dementia – If a person gets this type of dementia, it’s usually because he’s had a major stroke, or one or more “silent” strokes, which can happen without him realizing it. The symptoms depend on which part of his brain was affected by the stroke. While Alzheimer’s usually begins with memory problems, vascular dementia more often begins with poor judgment or trouble planning, organizing, and making decisions.

Symptoms – Memory problems that disrupt your loved one’s daily life, trouble speaking or understanding speech, problems recognizing sights and sounds that used to be familiar. Being confused or agitated, changes in personality and mood, problems walking and having frequent falls.

Dementia with lewy bodies – Lewy bodies are microscopic deposits of a protein that form in some people ‘s brains. They’re named after the scientist who discovered them.

If someone you know gets DLB, it’s because these deposits have formed in the part of the brain called the cortex.

Symptoms – Problems thinking clearly, making decisions or paying attention, memory trouble, seeing things that aren’t there, known as visual hallucinations, unusual sleepiness during the day, periods of “blanking out” or staring.

Problems with movement, including trembling, slowness, and trouble walking. Dreams where you act out physically, including, talking, walking and kicking.

10,000 Digits Of Pi

More often people complain about having a terrible memory, things like birthdays, anniversaries, grocery lists, etc. tend to slip off their minds. One might imagine memory like something set in stone but it is not the case, with the right technique you can train your brain to remember almost anything you want. A four-time USA Memory Champion, Nelson Dellis, who has memorized 10,000 digits of pi, the lists of hundreds of names after only one hearing, and the order of more than nine shuffled cards, says that anyone can improve their memory with a little dedication. Here are five steps that can help in training your brain to remember things.

  1. Start With Strong Images- Dellis suggests that to memorize anything, start turning it into an image. Let u take seven wonders of the world, for example, for the Great Wall of China you might just want to imagine a wall or for Petra of Jordan, you can just go for an image of your pet. Images that are weird or gross or emotional tend to stay in the brain for a longer time. When looking at the brain, researchers found that the amygdala—a part of the brain that is important for processing emotion—encourages other parts of the brain to store memories. That’s why strong emotions make it more likely that memories will stay.
  2. Put Those Images in a Location- Next, you have to locate those mental images in a setting that is familiar with you. Using Dellis’ example, he locates the seven wonders of the world on a route through his house, starting with a wall in his entryway, then Christ—representing Christ the Redeemer— lounging around on his sofa. He also mentions that the weirder the location, the better are the chances of staying in the memory. Linking images to a place are called the memory palace, which capitalizes on your existing memory of a real place. It is usually a place you are familiar with, which can be your house or workplace which you know very well. Neuro-imaging research has shown increased activity in the occipito-parietal area of the brain when learning memories using a memory palace. This technique helps the brain to bring in parts that are dedicated to other sense-the parietal lobe is responsible for navigation, and the occipital lobe is related to seeing images.
  3. Pay Attention- Memorizing seven wonders of the World is not as hard as memorizing 10,000 digits of pi or 100 names in one hearing, and doing that needs more motivation and more attention. According to Dellis, he motivates himself with the mantra “I want to memorize this”, it may be simple but this mantra helps him focus on the task by concentrating his attention on the task in hand and it helps him remember better.
  4. Break Things Up- For a long sequence of cards or a large number, it is a good technique to break things up into smaller sequences. Dellis says that it is easy to remember words as you can associate words easily with images but numbers or names or cards can be tricky, and for that, he has a technique that whenever we see a name or a number or a card, we already have an image preset for it.
  5. Finish Up by Reviewing– After getting the images and their location sorted in the memory, all we have to do is make sure that it stays in the brain. Most of the memories don’t even get to the long-term memory part of the brain and that is why it is important to repeat the information, again and again, to turn short-term memory into the long term. There is no shortcut for that, all you have to do is practice and persistence.

Training the brain is not as easy as it sounds or seems, it takes a lot of efforts, repetiton, hard work and training on a daily basis. Train hard, work hard, practice hard, then it can become instinctive, says the memory champion.
