Rarely Getting Sunlight? The Effects on Your Body
Jakarta (ANTARA) – Excessive exposure to sunlight can have harmful effects, including sunburn, dark spots and an increased risk of skin cancer.
There is also a belief that dermatologists advise people to stay indoors and avoid the sun because of its harmful effects on the skin. So, should we always avoid sunlight?
It is important to understand that sunlight is not always harmful. Exposure for an appropriate length of time can provide a range of benefits for the body.
The idea that people should always avoid the sun is also misplaced. Dermatologists recommend protecting the skin from extreme sunlight, rather than avoiding it altogether.
Going outdoors and getting some sunlight is fine, provided you take appropriate precautions, such as using sunscreen and wearing sunglasses or a hat.
The amount of sunlight a person needs also varies according to where they live, their skin tone, age, medical history and diet.
WebMD reports that, in general, five to 15 minutes of sunlight a day can have a positive effect on the body.
Anyone can get too little sunlight. Some people spend more time indoors because of work, have limited ability to go outside, or live in areas with shorter daylight hours.
If this happens regularly, a lack of sunlight may affect a person’s health. Some of the possible effects are outlined below.
Weakened immune system
Vitamin D produced with the help of sunlight can support the immune system in producing proteins that fight disease-causing pathogens. A vitamin D deficiency can impair immune function, making the body more vulnerable to infections such as flu and colds, as well as other illnesses.
Fatigue and difficulty sleeping
The Healthy reports that insufficient sunlight can disrupt the circadian rhythm, or the body’s biological clock, which regulates the sleep-wake cycle. This may cause fatigue during the day and poorer-quality sleep at night, and can even contribute to insomnia.
Bone pain
Too little sunlight can cause pain in the muscles and bones. Vitamin D helps the body absorb calcium and minerals that support bone health. Over the long term, low vitamin D levels can lead to osteoporosis, or weakening of the bones.
Weight gain
A lack of vitamin D may reduce energy production in cells and weaken muscle strength. This can leave people feeling tired and with less energy for exercise or physical activity. Reduced movement may increase the risk of weight gain.
Depression
According to the Mayo Clinic, insufficient sunlight can lower serotonin levels. This brain chemical helps regulate mood, and low levels may trigger depression in some people.
