Skylights and Health: The Psychological and Physiological Effects of Natural Light 3

The Importance of Natural Light in Our Lives

The importance of natural light in our lives cannot be overstated. Light affects our sleep patterns, hormonal balance, mood, mental stability, and even our physical health. While most people are aware of its role in regulating our circadian rhythm, not many know that exposure to natural light can have positive effects on our cognitive, emotional, and behavioral health.

Unfortunately, our modern lifestyle has made it harder for us to access natural light. Many of us spend most of our time indoors, either working at a desk or staring at our screens. This has significant long-term consequences on our health and wellbeing.

The Psychological Benefits of Skylights

While many people understand the physical benefits of natural light, few realize the profound psychological benefits of skylights. Research has shown that exposure to natural light can have a significant impact on our emotional and mental state. Skylights have the power to reduce stress, anxiety, depression, and seasonal affective disorder (SAD).

One study examined the effects of daylight exposure in an office environment on employees’ wellbeing. They found employees exposed to natural light experienced a 51% reduction in eyestrain, a 63% reduction in headaches, and a 56% reduction in drowsiness (Vierte). The study even found that employees that had access to natural light performed better on tasks requiring attention, concentration, and memory recall (Vierte).

Another study in a mental health facility found that patients in rooms that offered natural light had shorter hospital stays and lower levels of depression (Walch). The results suggest that the inclusion of natural light can be an effective means of improving the overall psychological environment of a healthcare facility (Walch).

The Physiological Effects of Skylights

While the psychological effects of natural light may be more apparent, there are clear physiological benefits to having skylights as well. Exposure to sunlight is essential to maintain proper vitamin D levels, which are crucial for supporting bone health, immune function, and cardiovascular health (Holick).

Moreover, the exposure to natural light has been linked to other health benefits, such as a lower risk of obesity, diabetes, cancer, and heart disease (Holick). The research suggests that the benefits of natural light exposure extend beyond our psychological and emotional wellbeing, and can have a real impact on our long-term physical health.

Installation of Skylights

Skylights offer countless benefits to the overall wellbeing of individuals, but many people are deterred from installing them, considering the cost involved for the installation. The reality is that installation of skylights can offer a great return on investment and lower energy costs. By letting natural light into your home or commercial space through skylights, you can significantly reduce the amount of artificial light necessary. As a result, you reduce the amount of electricity used and lower your energy bills.

When installing a skylight, take into consideration the orientation of the window. North-facing skylights may not provide a lot of natural light, and south-facing skylights may produce too much heat in the summer. It is advisable to work with a professional when deciding on a skylight to ensure that you get the optimum positioning and size that your space requires.


The benefits of skylights and the power of natural light are undeniable. It is essential to make an effort and integrate natural light into your life by adding skylights to your indoors. You can benefit from both the physical and psychological effects of natural light and enjoy improved health and wellbeing. Should you wish to install skylights, it is advisable to seek professional help to ensure that you make the most of what natural light has to offer.
