Medical professionals and scientists think that various cancers grow in the human body when cancerous cells replenish through division. Through chemotherapy, it wipes out a wide range of cells indiscriminately without particularly focusing on the source of cancer.Hopefully, shortly researchers will, pinpoint cancer originators and block those cells from duplicating without interfering with other healthy cells.

Cell Renewal and Cancer

Cells That Never Leave

The body replaces itself with a new set of cells every seven to ten years. This has been discovered by Swedish molecular biologist, Dr. Jonas Frisen.When it comes to aging, our DNAs remain the same from the day of a cell's birth throughout its lifespan, however, most new atoms are taken in through the air we breathe, the food we consume, and the liquids we intake.

Body Rejuvenation

The body renews itself at varying paces, for example, the lifespan for the following:<ul><li>The skin rejuvenates every 2-4 weeks;</li><li>The hair, about six years for women and three years for men;</li><li>The liver rejuvenates every 150-500 days;</li><li>The stomach and intestines, every five days due to corrosive acids;</li><li>The bones take a full 10 years.</li></ul>

Does your body really replace itself every seven years?

Sleep paralysis is a neurological phenomenon in which a person awakens from sleep but is temporarily paralyzed.
The episode may last a few seconds to minutes and is accompanied by the strangest hallucinations. It can feel terrifying.

Sleep paralysis

<ul>
<li>Understanding what is happening during sleep paralysis helps to prevent fear cycles. People are relieved to hear they are not "crazy".</li>
<li>Literally turn your back on the terrifying monster by dreaming a coherent dream in which you are aware you are dreaming.</li>
<li>Meditation relaxation (MR) therapy was designed to treat sleep paralysis. The treatment includes techniques of cognitive reappraisals, emotional distancing, meditation, and muscle relaxation.</li>
</ul>

Controlling sleep paralysis

Sleep paralysis often occurs when we take a nap, when jet-lagged or sleep-deprived. We wake up while still in the stage where vivid dreams occur, called the rapid eye movement sleep (REM).
During REM, the front brain - central to our ability to plan and think logically - turns off and makes our bodies temporarily paralyzed. It prevents us from acting out "real" dreams. Sometimes we wake up in this stage. The vivid and sometimes threatening dreaming of REM can "spill over" into conscious awakening. It can feel like a nightmare coming alive.

Neurological origins of sleep paralysis

The most distressing during sleep paralysis is seeing an intruder that sometimes attacks the sleeper. Anything the imagination can invent can happen. Commonly, the intruder chokes the person by crushing his chest. The creature can include details like a demonic face with sharp teeth and cat eyes.
One explanation is that in the same way that people who are born with a missing arm may experience phantom limbs - they feel the missing limb - a person can 'feel' another phantom person during sleep paralysis.

Seeing a ghost

Research suggests that your beliefs about sleep paralysis can shape your experience.
In Denmark, people see sleep paralysis as something trivial caused by the brain. Egyptians fear dying from sleep paralysis and consequently have longer episodes. The fear will activate fear areas in the brain, making them more likely to wake up during REM. The escalating anxiety would worsen sleep paralysis, causing more intense bodily hallucinations.

Fear feeds terrifying sleep paralysis

Sleep paralysis can sometimes make us feel like we're floating outside our body. The out-of-body experience can reliably be reproduced in the laboratory by disrupting the temporo-parietal junction in the brain. This region helps build a body image based on inputs it receives from the senses. The area is usually turned off during REM sleep.
In sleep paralysis, there is no feedback from the body telling the brain how to build the body image, resulting in out-of-body hallucinations such as seeing your body float in the air or sink deep into the bed.

Out-of-body experiences

Sleep paralysis, which 20 percent of people experience at least once, can be terrifying. Though it is a neurological phenomenon, our culture and beliefs can make the experience worse. One potential treatment is to learn to control the content of our dreams.

Sleep paralysis: a terrifying encounter with our own mind

A chronotype is what a person's sleep cycle calls under, whether they're a night owl, an early bird, or somewhere in between.
One's chronotype is determined by a combination of nature and nurture. Respectively, one's genes determine whether one prefers to be awake late at night or early in the morning; whereas nurture is how we choose our lifestyle.

The Sleep-Wake Cycle

What you participate in or what your daily activities are are usually what reinforces your chronotype.

Sleep Habits: The Environment's Role

<ul>
<li>Make the change gradually. Don't let your body go into shock. It is preferred if you set your alarm 15-20 mins earlier for the past several weeks until your adjusted to your ideal schedule.</li>
<li>Consistency is key.</li>
<li>Limit exposure to light an hour before bed because it blocks the body's production of melatonin.</li>
<li>Avoid stimulating activities during the time you should be asleep.</li>
</ul>

Being in a bad place mentally is extremely difficult when going through it alone, however, the good thing about the modern world is it offers three main sources for solace:
<ol>
<li>Psychiatric medicine</li>
<li>Cognitive Behavior Therapy (CBT)</li>
<li>Psychotherapy.</li>
</ol>

The Modern World's Solace

These are psychiatric sessions that last around 6 to 10 hours where we learn techniques to argue rationally with our irrational mind. 
Our internal persecutors like paranoia, low self-esteem, shame, and panic, will be tackled. We'll then be able to distinguish facts from irrational thoughts.

Cognitive Behavior Therapy

At a first glance, it seems like psychotherapy is not an option you'd like to get yourself involved in since it requires a large amount of your time, active engagement, and sustained emotional efforts. 
However, psychotherapy is a great way to correct our self-ignorance in the most profound ways. It provides a safe space to let ourselves heal consciously.

Psychotherapy

When administered correctly, the medicine we get from our psychiatrist helps correct the chemical imbalances of our brain that help us get through our daily lives. 
The side effects of these may range from nausea to sleepiness, but with it, we'd be able to function... more or less.

Psychiatric Medicine

<ol>
<li>We are able to make our unconscious feelings become conscious. Since experiencing trauma we are unable to grasp what we truly long for. We learn here crucial ideas and feelings that come from our unconscious to be exposed and healed.</li>
<li>Transference. Here we learn where our impulses come from and develop less self-defeating ways of interacting with people moving forward.</li>
<li>It is most likely our first good relationship. The therapist is the first truly supportive and reliable person we've encountered.</li>
</ol>

Another day has passed and it's time to wind yourself down again. Meditation changes our state of mind. It can energize you, soothe calmness into you, or even both. It allows our bodies to become present in the moment. 
If meditation isn't for you, there are other ways to sooth yourself like the box-breathing method, or yoga.

Meditate

There are some projects that we aren't able to finish in a day, but luckily for us, there's always a chance to finish it tomorrow.
So whatever task you have left from work, jot it down so you won't forget about it.

Make a list of remaining tasks

Everyone who's been to a spa knows how relaxing the atmosphere of the place. You can do that too at home by lighting an aromatic candle, lights down low, some calm relaxing music playing in the background, and a diffuser with green tea and bamboo oil is scenting up the place. 
De-stress yourself with those and include a little stretching here and there, but don't forget to drink your water.

Candles and chill

Work hours are up! It's time to get some relaxation going and it's harder to relax with constant buzzing from your work e-mail and it's extremely tempting to check them. 
Practice "Out of sight, out of mind."

Put your work stuff away

Either you just take a walk around the block for 15 minutes or have an extreme workout session at the gym, it can help get your mind off of work.
Sometimes its better to get your blood going, stretch your limbs, and transition into relaxation mode.

Do something physical

After a long day of working, call a friend and just share laugh with them. Or just have an intimate conversation with your significant other. 
"A simple video call with your loved ones is just a humanizing feeling, it helps us reconnect and regenerate the jolt to put the workday behind."

Talk to your friends or family
