Avoiding the Sun Can Harm Your Health

Avoiding the Sun Can Harm Your Health

Most of us know that too much sun can lead to sunburn and increase the risk of skin cancer. But what many people don’t realise is that not getting enough sunlight is also bad for your health.

In Malaysia, we are lucky to have sunlight all year round, yet many of us avoid it. We stay indoors, work under artificial lights, and cover ourselves up even when outside. But science shows that this lack of sun exposure can lead to serious health problems.

Here’s what the research says about why sunlight is important, especially if you follow a plant-based diet.

Sunlight Helps Your Body Make Vitamin D

The most well-known benefit of sunlight is vitamin D production. Your skin makes vitamin D when exposed to UV rays from the sun. Vitamin D is important for many things — it helps absorb calcium, supports the immune system, and keeps your muscles and bones strong.

One study by the University of Florida found that avoiding sunlight can lead to a higher risk of weak bones, worsen seasonal depression, and even certain cancers. People who don’t get enough sun tend to have low vitamin D levels, and this can affect how well your body functions.

This is especially important for people on a plant-based diet. Most natural sources of vitamin D come from animal-based foods like fatty fish, eggs, and liver. While there are plant-based alternatives like fortified soy milk and mushrooms, they may not provide enough. That’s why sun exposure becomes even more important for those avoiding animal products.

Low Sunlight May Weaken Your Immune System

When your body lacks vitamin D, your immune system doesn’t work as well. This means you may fall sick more often. According to research from the University of Florida, sunlight also helps regulate your body clock, which affects your sleep, mood, and immune response.

People who avoid the sun may suffer from sleep problems, low mood, or even depression. These problems are more common in countries with long winters, but they are becoming more common in Malaysia too because of our indoor lifestyles.
