Keep aside the global impacts, at the micro level, adequate exposure to
the sun triggers necessary changes in the body of living organisms to
help soundly function mentally and physically.

3. Why Is Sunlight Important?
Sunlight affects humans in both good and bad ways but its benefits
outweigh far too much than the adverse impacts. Sun rays impact a
wide array of bodily functions from the sleep cycle, and energy levels to
mental health, and more. For example, sunlight assists in Vitamin D
synthesis and provides serotonin which aids in bone strength and our
sleep-wake cycles respectively. Besides, numerous other aspects make
sunlight so indispensable that it cannot be emphasized. Under this light,
it is important to note that not getting enough sunlight can cause
adverse impacts for example weakening of the immune system, and
increased vulnerability to diseases such as osteoporosis, cancer, the flu,
etc.
Let us have an in-depth look into some of the health issues arising out of
lack of adequate exposure to sunlight.

4. Irregular Sleep-Wake Cycle
Sunlight aids in the production of hormones namely, serotonin and
melatonin. Together, these two regulate sleep-wake cycles and help us
keep a consistent schedule. Serotonin helps us wake up and melatonin
assists in sleeping. In case of too little sunlight exposure, one may have
trouble getting tired and wanting to sleep at night. Similarly one may
feel exhausted and hard to wake up during the day especially due to
melatonin deficiency.

5. Weight Gain
An inadequate sun bath is likely to throw off sleep cycles and make one
feel tired more often. This exhaustion due to less sun exposure can
affect body metabolism and trigger our body’s want to consume too
much food to compensate for the energy lacking. Sun’s UV rays also aid
in the production of the body’s nitric oxide, a nutrient that ensures the
smooth working of metabolic processes. So lack of sunlight may hamper
nitric oxide formation which leads to weight gain.

6. Low Productivity
Serotonin formation in our brains triggered by sunlight gives us the
necessary energy we need to think, focus, and complete tasks all day
long. Sunlight exposure also aids in the production of Vitamin D. So
when we don’t get enough of it, our body doesn’t create serotonin or
vitamin D to the required level. This makes people tired and lethargic as
a result it becomes difficult to focus on anything.

7. Hypertension
Lack of sunlight can cause stress levels and blood pressure to shoot up. A
report from 2020 finds that UV radiation from the sun can be associated
with lower blood pressure. Hypertension can put you at risk for heart
disease or stroke, so it’s best to make it a habit of spending some time
outside in the sun.

8. Nearsightedness
Everyone knows how looking directly into the sun can damage eyes, but
lack of sunlight may also be bad for eyesight. It’s very much possible
that inadequate sunlight exposure can cause nearsightedness or
inability to see things clearly unless they’re near.

9. Higher Risk Of Cancer
A study reveals that those living in areas with less sun and those
affected by vitamin D deficiency have more risk of developing common
cancers.
Mental Illnesses
Low levels of vitamin D and serotonin deficiency have often been linked
to triggers of depression, and other issues like low self-esteem,
irritability, OCD, and anxiety.

10. Seasonal Affective Disorder
For some folks, lack of sun in winter months can cause them to feel
depressed and suffer from mood fluctuations. This is quite common in
cold countries where people don’t get exposed to sunlight for many
days or weeks.
Weak Bones & Teeth
A major aspect of vitamin D is that plays a pivotal role in maintaining
bone strength and tenacity. Sunlight aids in our body’s ability to absorb
calcium and collagen, which keeps our bones and teeth strong and
healthy. So, inadequate sunlight exposure or vitamin D deficiency can
lead to several problems like bone loss and osteoporosis in the body.

11. Weak Immunity
Vitamin D and healthy sleeping habits both determine the quality of the
immune system in the human body. Lack of sunlight keeps deters from
sleeping well and also makes one vitamin D deficient, thus it hits the
immune system causing such people to fall sick more often. Vitamin D
deficiency especially has been found to make people more vulnerable to
colds and flu, as well as infection and autoimmune issues.
