Self renewal: 10 hard facts πŸ™Œ

Hello everyone πŸ––

1. The human body in which each of us lives is made up of around 37 trillion cells, to be precise. And every day, about 1-2 percent of the cells are renewing. So, exactly after 90–100 days, a new “me” appears. We remain so busy with our routine lives that we hardly acknowledge this fact, and many of us are not even aware of it. So, β€˜change’ is the constant tune, not just within the universe but also within us.

2. Now that we understand that our bodies undergo transformation on a daily basis, So, the question is: how does this self-renewal occur? Let’s go back to our past a little bit. The human body develops from the human embryo, which is fertilized by an oocyte and a sperm cell. This embryo is made up of stem cells. The stem cells are the basic cells (undifferenciated cells) of the human body, which, through the process of mutation and transformation grow into different cells like nerve cells, bone cells, muscle cells, blood cells and so on. Throughout our lifespan, these stem cells undergo cell division and keep replicating; that’s how self-renewal happens.

3. Under normal physiological self-renewal processes, different cells in the body have differing rates of cell division. So, the replication process of various tissues, organs, and blood cells in the body has a different time frame, like the skin epidermal cells, which can take around 10–30 days, whereas a bone cell takes 3 months, or a hair grows about 1 cm in one month, and so on.

4. Though our body is constantly changing due to the continuous self-renewal process through different cell cycles like shedding the old skin cells, renewal of intestinal cell lining, and growing hair or nails on a routine basis, this isn’t a simpler process. The human body is still very complicated and has exceptions. Some cells, such as those in the brain (cerebral cortex), eyes (such as lenses), and heart, do not change from birth to death.

5. But then, why is self-renewal important and must be maintained? Under normal physiological conditions, stem cells have two functions: proliferation and differentiation. Though stem cells have a natural proliferative capacity throughout our lives, disease conditions can affect their physiological self-renewal ability and behavior due to factors such as damage or an unhealthy lifestyle (obesity, lack of physical activity, smoking, or a poor diet).

6. A lack of an appropriate environment within the body or poor maintenance of the human body might eventually lead to the exhaustion of the capacity of stem cell proliferation, which causes premature aging or tissue atrophy. With aging, stem cell activity, tissue regenerative and haemeostasis is significantly declined.

7. Sometime, due to the unhealthy environment within the body, mutations lead to aggressive stem cell division without going through the natural cell differentiation process. This can lead to abnormal tissue growth or cancer in the body. Therefore, the physiological process of stem cell division and the natural stem cell behavior can be affected by four disease conditions, like degenerative, metabolic, cardiovascular, and inflammatory conditions.

8. Regenerative medicine and therapies have arisen as a result of the discovery that defective self-renewal mechanisms in the body are the root cause of malignancies and abnormal cell proliferation. Many disorders are being treated with regenerative medicines based on stem cells. Recent years have seen a significant increase in the use of stem cell treatment to treat a variety of diseases like cancer and disorders including type 1 diabetes, heart disease, stroke, Parkinson’s, burns, osteoarthritis, by regenerating cells, repairing tissues, and transplanting organs.

9. The fact about regenerative medicine is that, though it has helped many patients around the world, the cost of treatment is quite high as the procedure is complicated and the failure rate is high. Human stem cell treatment requires culturing human stem cells in a laboratory setting for a longer period of time, which is quite difficult.

10. The market is flooded with products that promote cell regeneration, anti-aging, and longevity. The lofty claims made by these items are still quite dubious. But it is true that some supplements do work to improve health, lower inflammation, and increase immunity. But in the end, having a healthy diet, getting enough sleep, a calm mind, and exercising regularly is all that’s necessary for good health.

Immunity : 8 signs to indicate that your immunity is intact πŸ™Œ

Hello everone ! Have a wonderful and great day πŸ™‹πŸ»

1.You have a bodyweight within the range of average weight, according to the height and not being overweight.
2.You have a routine, regular bowel habit.
3.You have clean and clear skin.
4.You get up fresh and remain energetic. There is an absence of laziness.
5.Experiencing a sense of hunger once or twice a day.
6.You don’t have general body ache except with injury or heavy exercise.
7. You experience a sense of wellbeing and generate positive thoughts.
8. You experience deep sleep at night.

These are general signs that indicate that your body is functioning optimally and your immunity is intact. Our body’s immunity and vitality is not acquired by having a glass of smoothy, or daily going to the gym and having a load of supplements. It is the result of what you eat, how you think and how you live.

Three simple ways to build up a strong immunity is:

1.Fasting: Fasting is the simplest and easiest way of building your immunity. Ideally,15 to 16 hours of fasting every day are good enough. It is also the easiest way of losing weight. Having everyday dinner at around 6-7 PM, and not having any meal or snacks in between except water. Then, followed by having breakfast, the next morning around 10 to 11 AM gives you fasting of at least 16 hours quickly.

2. Food: Having food which is as much as close to Mother Nature. Fruits and vegetables, in their natural form or cooking minimum to restore their nutritional value. Preferable having a one-grain meal a day like brown rice or whole wheat and having meals (1-2 times /per day) with enriched portions of fibres, healthy saturated fat, protein and carbohydrate. It is necessary for avoiding processed, refined food altogether. Limiting the intake of beverages, alcohol and having more water, instead is ideal.

3. Mind and body care: Exercising every day is a must. Instead of heavy workouts in the gym, simple exercises like walking in nature, running, jogging are ideal. Physical activity throughout the day is good enough to give you a good night sleep. It is essential to maintain a positive attitude and a calm mind, to keep stress at bay. So, meditation, yoga, mindfulness practices, spiritual practices helps to build a positive and healthy mind.

Hair health πŸ™Œ

Hello everyone ! Have a great and safe Sunday β˜€οΈπŸ™‹πŸ»

Our hair is the crown, we never take off. So, hair is a significant part of our physical appearance; hence it is crucial. Structurally, hair consist of a protein called keratin. A hair follicle supports each hair shaft. The root of each hair follicle lies the hair bulb. It is in this hair bulb; new cells develop and grow and give rise to the latest hair follicle. The hair bulb contains the blood vessels which nourishes and supply necessary nutrients to the cells to grow and develop. The colour of the hair depends upon pigment cells called melanin. The structure and texture of the hair are related to genetic predisposition.
Each hair grows through a cycle of 3 phases:

Growth phase: In this phase, the hair is growing in prominence.
Transitional phase: When the hair stops growing, matures and the hair follicle start to shrink.
Resting phase: When the old hair fall, cells die, and new cells start to develop and grow.

Typically with ageing, the hair pigment cells die, and hair begins to turn grey and fall. But, in the recent decade, due to environmental pollution, harmful UV rays, unhealthy lifestyle, unhealthy hair treatment, hair thinning, hair greying and hair fall has become very common even in the young age group.

Some common causes of hair thinning and hair fall:

1.Poor nutrition: Unhealthy eating habits like eating junk food, processed food, artificial sweeteners, cola, juices does not provide any nutritional value but instead add to empty calories to the body. Again, some people go on a crash diet, leaving behind necessary nutrient-dense food like healthy fat has to suffer hair fall. When the body does not get enough nutrient-dense food, it transports the remaining nutrients to the vital organs. It is the hair which is left neglected. Hence hair fall, hair thinning and low growth.

2.Poor Blood circulation: Sometimes, even if you have a well balanced nutritious diet, yet you may face hair issues. Hair problems happen because the blood nutrients are unable to reach the cells in the hair bulb. So, massaging the scalp is essential to stimulate the blood circulation and enrich the hair bulb with the necessary nutrition. Even physical exercise is critical. Daily routine exercise, causes proper movement in the body which ensures efficient blood circulation in every part of the body, including the scalp. Women suffering from hormonal imbalance and thyroid issues, suffering from hair fall, exercise is highly recommended.


3.Excessive stress: This is important because, in a chronic state of stress, the body tends to remain in the sympathetic mode, which blocks the body’s normal functioning of growth and renewal mechanism.


4.Heat and chemicals: Heat is very harmful to hair. Hot water baths, use of excessive hair styling methods like hair drying, hair straightening, hair curling are all harmful. Tying hair too tightly all the time may affect the hair root. Avoiding too many hair products, colouring agents, and toxic chemicals like sulphate can cause hair damage. Fragrance hair products may contain alcohol which is harmful also.

Measures to protect and keep hair healthy:

1.Nourishment: It is vital to keep the scalp healthy and clean to have healthy hair. So, cleaning the scalp 2-3 times a week with a mild shampoo is essential to remove pollutants and impurities. Massaging the scalp gently 5-10 mins, 3-4 times a week will improve the blood circulation drastically. Natural oil like coconut, almond or jojoba oil is nourishing and can be used for hair massage.

2.Exercise: Regular exercise is essential to ensure proper blood circulation to provide necessary nutrients to the body, including the scalp.


3.Drinking water is overall healthy and good for hair too.
4. Five Superfoods for hair:


Eggs: They are in rich in protein and biotin. Keratin which is protein is present in each hair strand, so protein intake is crucial for hair. Biotin gives strength to hair and promotes hair growth.


Green leafy vegetables: Dark green leafy vegetables and spinach are rich sources of iron, vitamin A and C. Adequate iron is required to produce haemoglobin in the blood. Haemoglobin is essential to transport oxygen to cells, and hence, it is suitable for scalp and hair growth. Other rich sources of iron are beans, pulses, soya, seeds, nuts, broccoli and cabbage.

Vitamin B12: It helps in hair growth and texture. The sources are meat, fish, salmon, milk, dairy products, eggs.


Fat-soluble vitamins: Vitamin D, E, A, K are all essential for hair health. Consuming healthy fat of omega-three fatty acid is not only good for hair health but also help in the absorption of fat-soluble vitamins. Vitamin A helps in the production of sebum which nourishes the hair. Sources are sweet potatoes, carrots, seeds and nuts.
Vitamin C and E are potent antioxidants and prevent free radical damage. Therefore, they are protective of hair.
Sources are Lemon, berries, almonds, avocados, spinach, guavas.


Zinc: Zinc promotes hair growth and repair and prevents hair loss. Sources are meat, shellfish, sprouts, pumpkin seeds and sesame seeds.
