As the video is 2 hours long, I have summarized the key points of Dr. Seheult

 What Dr. Shulets is explaining in the video is  that
  1.  Melatonin antioxidant to neutralize reactive oxygen.  Melatonin is produced by our body starting in the evening  9:00 PM and during sleep till the morning 7:00 AM. So, it is important to have a regular sleep cycle.  
  2. Near Infrared light by Sun directly stimulates the mitochondria factory  (organism) to produce melatonin to neutralize reactive oxygen molecules which are produced during ATP production.  
  3. 95% of Melatonin is produced by Mitochondria.
  4. Vitamin D is produced by ultra violet regions of sunlight but Mitochondria is stimulated in Near Infrared region of sunlight.
     ** Note that oxidative stress means that there are more reactive oxygen molecules than antioxidant molecules such as Melatonin.
     **  Reactive Oxygens are important for our immune system.  Neutrophil (WBC) and Macrophages uses Reactive Oxygen to kill pathogens. 

Take home lesson is that we sleep early, don’t look at screens after 8 PM, wake up early to bathe in the Sunlight till the body feels warm.  This will improve the production of Melatonin (antioxidant) and  help reduce oxidative stress by neutralizing reactive oxygen, thus helping prevent various diseases, including Covid-19 virus and cancer.   Below is the link to the video which Dr. Shulets explains the benefit of sunlight in fight against the corona Virus.   

Below is the summary of my train of thought to understand the video of Dr.Shulets. 

 The human body is approximately 99% comprised of six elements (six kinds of atom):  66%  oxygen atoms (O), 18% Carbon (C ), 10% Hydrogen (H), 3% Nitrogen (N),1.4% Calcium (Ca), 1.1% Phosphorus(P). Another five elements make up about 0.85% of the remaining mass: Sulfur, Potassium (K), Sodium (Na), Chlorine (Cl), Magnesium (Mg).   Trace elements make up 0.05%: Iron (Fe), Fluorine (F), Zinc (Z) and other elements..

There are 118 elements (different atoms) in the universe and 60 different elements are found in our body.
When those elements bind together, they make up different molecules.  A cell including a urothelial cell of the bladder is made of  water (65%), Lipids (12%), Protein (20%), RNA (1%), DNA (0.1), other inorganics (1.5%), Other organics (0.4%).
Water (H2O),   Lipids (CH3(CH2)nCOOH), Protein chain of 20 kinds of amino acid (R-CH(NH2)-COOH), DNA (C15H31N3O13P2) -  Adenine (C5H5N5), Guanine (C%H5N5O), Thymine (C5H6N5O), Cytosine (C4H5N3O).  

Oxygen atom is very reactive (unstable), meaning  that it is missing two electrons to become non-reactive (stable) so it tends to steal electrons from molecules nearby.  In reality, there are abundant oxygen atoms in our body so two atoms quickly bind together to become an oxygen molecule (O2) by each oxygen atom sharing two unpaired electrons.  An oxygen molecule though it is non-reactive normally, it becomes reactive when it loses an electron. The reactive oxygen molecule now hunts for an electron from nearby molecules, by stealing an electron from a molecule or binding to the molecule.   If the affected molecule happens to be a part of DNA of a cell,  it may lead to the cell death because the cell cannot divide due to an error in DNA, or if the affected molecule is a key gene related to cancer and the DNA is not repaired and if the cell does not die, the cell with mutated gene will be created and duplicated and it can lead to cancer.      

There are several situations in which our body produces oxygens.  The main product of reactive oxygen is by mitochondria organisms in our cells.  There are 100-200 mitochondria in each cell. Mitochondria is like a mini factory. The main product mitochondria produces is biological energy called ATP (Adenosine Triphosphate).  Mitochondria produces ATP by consuming Glucose (sugar) which our body produces by digesting carbohydrate which we eat  and oxygen molecules which we breathe in and delivered in the form of hemoglobin - red blood cells.  As one of the by-products, Mitochondria produces toxic  carbon dioxide (CO2), which will be carried away by blood to lungs and exhaled out from our body..  Also, during the process of producing ATP, an electron(s) is removed from oxygen molecules (O2) to produce reactive oxygen molecules.    To neutralize toxic reactive oxygen molecules, our body produces molecules  which have an extra electron to give away. These molecules are called antioxidants.  .It is important that sufficient amounts of antioxidant molecules are produced to neutralize reactive oxygens which Mitochondria factory produces.  Melatonin is one of such antioxidants.

All of have a favorite online video channel to learn about  medicine.  One of my go to channels  is Medcram.  The instructor -  Dr Seheult , is quadruple board-certified doctor in  Internal Medicine, Pulmonary Diseases, Critical Care Medicine and a professor at the University of California, Riverside School of Medicine.  I had followed him almost everyday when the pandemic started because his explanation was clear and  in addition to his daily work treating COIVD-19 patients in ICU, he prepared the video frequently and explained about COVID-19, mechanism of action, evolving treatment options  and how we can best protect ourselves.  

Dr. Seheult is also a board certified in sleep medicine.  He just broadcasted how we can improve our health and immunity from sunline / sleep.  Below is  the link to the vide.  best
