Why you need sunshine in your life

Sunlight is imperative for the sustenance of almost every living being on our planet. This includes plants, animals, and even fungi!. But most importantly, sunlight is vital for us human beings because it plays a crucial role in the many key functionalities of our body. This article walks you through a few less commonly known reasons as to why sunshine is important for us.


Arguably one of the most important benefits of sunshine is the production of Vitamin-D. For the uninitiated, Vitamin-D is a vitamin that is produced by our body when it is exposed to sunlight (more specifically, it is the ultraviolet-B radiation present in sunlight that triggers this response). Vitamin-D is a fat-soluble vitamin composed of three main compounds; Vitamin-D1, Vitamin-D2 and Vitamin-D3.

Vitamin-D has a plethora of benefits for human beings, such as regulating the absorption of Calcium and Phosphorus, and Ensuring the immune system functions normally. Some further benefits of Vitamin-D include:

  • Strengthen bones
  • Helps in reducing depression
  • Strengthens your immune system
  • Reduces the risk of certain diseases
  • Accelerates weight loss process

Mood uplifter

Sunlight triggers the brain to release a hormone known as serotonin. Serotonin is synonymous with boosting moods, essentially making you happier. The significance of sunlight can be attributed to the fact that doctors treat patients suffering from Seasonal Affective Disorder ( SAD ) or depression with natural or artificial light. 

Sunlight contributes in reducing your anxiety and brain fog ( the lack of mental focus and clarity ). Serotonin present in sunshine also aids in eating and digestion.

Lowers blood pressure

Sunshine has proven to reduce blood pressures in people. A compound known as nitric oxide is released into the bloodstream when sunshine touches your skin. The release of this compound helps reduce your blood pressure; which can subsequently reduce the probability of heart diseases and stroke.

Helps you sleep better

Research has shown that exposure to sunshine assists in maintaining your circadian rhythms. The circadian rhythm is an internal process that regulates your sleep-wake cycle. A normally functioning circadian rhythm means your internal clock will be set. Which means you are less likely to experience sleep disorders such as insomnia and get a good night’s sleep.

Cancer prevention

Sunshine, in controlled amounts, has the ability to prevent certain cancers. Research has shown that people living in areas with fewer amounts of sunshine have a higher risk of contracting certain cancers than those with relatively higher sunshine exposure. Some of the cancers are:

  • Pancreatic cancer
  • Prostate cancer
  • Colon cancer
  • Ovarian cancer

Ability to heal some medical conditions

The WHO ( World Health Organization ) believes sunshine to be useful in treating some skin conditions. Patients are recommended UV radiation to skin diseases such as:

  • Psoriasis
  • Eczema
  • Jaundice
  • Acne

Alongside curing skin diseases, early research suggests that sunshine may have positive effects against other miscellaneous diseases, some of which include:

  • Thyroiditis
  • Inflammatory bowel disease
  • Rheumatoid arthritis
  • Systemic lupus erythematosus  

Can potentially increase your lifespan

Early research found out that exposure to sunshine can increase your lifespan. A study involving around 30,000 people concluded that the people who had more exposure to sunlight went on to live up to 6 months to 2 years longer than those who had lesser exposures.
