🌞 Sunlight's Mood-Boosting Effects

This paragraph discusses the psychological benefits of sunlight beyond the production of vitamin D. Sunlight exposure triggers chemical reactions in the skin that lead to the generation of vitamin D from cholesterol, a substance necessary for this process despite its negative reputation. Moreover, sunlight hitting the retina through the eyes leads to an increase in serotonin levels, a neurotransmitter that significantly impacts mood. This explains the mood upliftment during sunny days and the depressive feelings during darker seasons. The speaker shares a personal anecdote about moving from Washington State, known for its rainy weather, to California near the Mojave Desert to improve their mood due to the lack of sunlight.

Keywords

💡Vitamin D

Vitamin D is a fat-soluble vitamin that is essential for the absorption of calcium and phosphorus, promoting bone health and immune function. In the context of the video, it is mentioned that the Sun's rays trigger a chemical reaction in the skin that converts cholesterol into vitamin D, emphasizing the importance of sunlight exposure for vitamin D synthesis.

💡Cholesterol

Cholesterol is a waxy substance found in the cells of all body tissues and is essential for the production of vitamin D, as mentioned in the script. Although cholesterol has been negatively associated with health, it plays a crucial role in the body's functions, including the synthesis of vitamin D when exposed to sunlight.

💡Serotonin

Serotonin is a neurotransmitter that contributes to well-being and happiness. The video script explains that sunlight exposure can increase serotonin levels, which can improve mood. This is contrasted with the effects of reduced sunlight during winter, which can lead to lower serotonin levels and potentially cause depressive symptoms.

💡Melatonin

Melatonin is a hormone that regulates the sleep-wake cycle. The video script notes that sunlight exposure can reduce melatonin levels, which can help to wake a person up and counteract feelings of sleepiness that are associated with darkness or increased melatonin production.

💡Viral Loads

Viral load refers to the amount of virus present in a person's blood. The script suggests that the heat and humidity generated by the Sun can decrease viral loads, including that of COVID-19, by affecting the virus's ability to reproduce, which is why some viruses are more prevalent in certain seasons.

Transcripts

let's talk about some of the really interesting benefits from the Sun that

go beyond just vitamin D so as you know when the Sun hits your skin there's

certain chemical reactions that occur that generate vitamin D from cholesterol

in your skin so people are always against cholesterol but you need

cholesterol to actually make vitamin D okay so there's a lot of benefits to

cholesterol but check this out when the Sun hits your skin and the

retina okay through your eye you get a chemical conversion of increasing

serotonin and serotonin can greatly affect your mood this is why of course

when you're in the Sun you feel much better and when the winter comes and

it's dark you don't feel that great if it goes on and on

in fact when I originally graduated from college I wanted to go and live in

Washington State okay it was just beautiful there and I just loved the

whole scenery and and how green the grass was well little did I know the

reason why it's so green is it rained so much in fact for six months I don't

think the Sun came out at all and I got really depressed so I moved from

Washington State down to California actually right next to the Mojave Desert

to dry out all the Sun and my mood definitely went up so there is a

relationship between the Sun and your mood via certain hormones okay number

two it effects melatonin actually reduces melatonin melatonin is the

hormone that helps you sleep so darkness stimulates melatonin but

light Sun will decrease this this makes you sleepy so the Sun wakes you up okay

so another benefit number three the heat from the Sun and the humidity that's

generated from the Sun and also the environment has the power to decrease

viral loads even from COVID-19 and this is why you're going to see as you go

into the summer you're going to find that a lot of people are going to do

much much better simply because the reproduction of that virus is affected

by the temperature and the humidity of the environment and this is why these

viruses a lot of times are seasonal like influenza comes out in the winter but

kind of goes away in the summer now number four UV this is a wavelength that

you're getting from the Sun that has antibacterial effects and this has

nothing to do with vitamin d UV inhibits the growth of certain bacteria and other

microbes even through glass it can actually inhibit tetanus typhoid TB

staph strep and many other microorganisms are number five the Sun

will increase resistance to infection so it helps your immune system alright

number six the infrared wavelength of the Sun is great for wound healing and

decreasing pain there's many different types of therapy using infrared and if

you haven't seen the benefits of vitamin D from the Sun you got to check that out

I put it right here
