15 Benefits of Sunlight – A Bright Spot for Human Health


Plants consume and metabolize sunlight, so do humans. However, the relationship between human sun exposure and wellbeing isn’t as simple as we might want it to be. Genes are a factor in how sunlight is metabolized by humans; just as skin type is.

Spring is soon followed by the scorching sun of summers and before we know it is that time of the year again when you take refuge at the seashores.  Welcome to the hot sunny days again!

When sunlight is felt on the skin, it acts as a catalyst to produce vitamin D in the body, often known as “sunshine vitamin”. Even a 5kw solar system in Sydney can generate electricity by storing power from the sunlight, just like energy is generated in plants and humans. This ingredient seems to be very vital for overall health. It guards against irritation, reduces increased blood pressure, strengthens muscles, and increases brain function. It also even guards against cancer, here you will almost 15 benefits of sunlight: 

#1 Exposure to the sun increases bone health

It is known to be that vitamin D enhances the synthesis of calcium and phosphorus fortifying the bone in the body. Nonetheless, recent work also suggests a direct association between vitamin D3 and bone density. Vitamin D3 is a fat-soluble vitamin that is produced during the manufacturing process of Vitamin D when sunlight hits the skin. This regulates the absorption of Calcium. You are at a greater risk of suffering from almost all forms of injuries whenever your blood has higher levels of vitamin D3. On the other side, lower blood vitamin D3 levels are connected with increased rates of fractures of all forms. For this reason, sun contact is very vital for bone health in older people.

#2 Sunlight Enhances Brain Functions

Other than from encouraging bone health and regulating vital levels of calcium, experts have connected vitamin D to a number of functions across the body, plus brain functioning.

Another study conducted by the University of Cambridge neuroscientist that is David Llewellyn, who measured levels of vitamin D in over 1,700 men and women of England. It also discovered that cognitive function decreased the lower levels of vitamin D of the subjects.

#3 Sunlight Keeps the Blood Pressure Low

High blood pressure is extremely dangerous, so educating yourself on ways to lower your blood pressure is important. One of these includes sunlight exposure. Evidence has shown that nitric oxide deposited on the skin’s top layer responds to sunlight, causing blood vessels to expand as the oxide passes into the bloodstream. It leads to lower blood pressure.

#4 Sunlight betters the quality of sleep

A message is delivered to the pineal gland in the brain when sunlight hits our eyes and melatonin development (a hormone which makes people lazy and allows us to sleep) is off until the sun went off again. Your body gets a clear indication that it’s no longer night, which helps keep a natural circadian rhythm.

#5 Sunlight reduced chances of Type 2 diabetes

Diabetes has sadly risen among individuals over the years. Vitamin D plays a huge role in insulin production, according to some clinic, and researches have proved a positive relationship between the deficiency of vitamin D and insulin resistance.

#6 Sunlight helps to relieve mild depression

Deprivation from sunlight can cause a situation known as a seasonal affective disorder in short SAD. SAD is a common method of sadness in winters. It is common also in people who work in the office for long hours and barely get out for sunlight.

#7 Boosted immunity system

It has been shown that sunshine stimulates vitamin D and T cells in your immune systems, resulting in increased immunity. Researchers explain that we all depend on solar power so that our bodies can escape fight disease and infections.

#8 Prevention of vitamin D lack

The research has revealed that the dearth of vitamin D is a problem for around half of the world population. Vitamin D, however, is also known as the sunshine vitamin. Therefore, the sun’s exposure nourishes the body through vitamin D. Over a billion individuals worldwide are vitamin D deficient (VDD).

#9 Prevents cancer chances

Evidence has confirmed that spring sunlight is a lot better for men because the second study of vitamin D indicates that it keeps them safe against the dangers of kidney cancer. Doctors say that vitamin D cuts down on the risk of a number of cancers and raises the survival rates.

#10 Losses weight

The lack of sunlight can lead to low levels of appetite. You also explain that starvation is controlled by the hypothalamus. The shortage of sunlight triggers a decrease in the amount of serotonin, which can contribute to a sense of completeness. Sunlight will, therefore, help you manage your appetite.

#11 Helps in healing skin issues

Sun exposure may help in the treatment of several skin conditions, according to the World Health Organization (WHO).

#12 Sunlight is a friend to your eyes

Sunlight is not the enemy of our eyes, in contrast to what others believe. The enhanced vision and the eye aging were related to vitamin D. Research suggests that the sun’s rays not only have a beneficial effect but a healing effect on the eyes.

#13 Sunlight cures depression

Sunlight exposure was associated with improved levels of the natural brain antidepressant. During sunny days, the brain generates an increased amount of serotonin. Therefore, people who have depression can experience fewer symptoms if they are exposed to sunlight.

#14 Sunlight gives a growth boost in kids

Its benefits apply in particular to infants. Studies show that a baby’s first few months of life show the extent of sun exposure that impacts the development of the infant. This is known by many cultures around the world and children are exposed to sunlight to boost growth and height.

#15 Sunlight reduces the symptoms of Alzheimer

Patients who are exposed to the sun all day at 9 a.m. have been shown by clinical research. Around 18:00. Followed by night silence, behavioral tests have been easier and some aspects of the disease have changed.


Sunshine has many benefits from the treatment of skin conditions to a better mood. A lightbox will offer some of its mood-enhancing advantages if you live in higher latitudes with little sunshine. For example, if exposed to too much sunlight, people with pale skin who burn easily in the sun will likely get skin cancer. Also, the timing and duration of exposure is a crucial factor in how our bodies metabolize the sunlight. Forget just for a moment about the sunshine and how it may result in skin cancer and how it has harmful ultraviolet radiation.
