If you all on a sudden get an urge to dance when the warm weather returns, just know that you are not the only one! This type of mood change can be explained partially by the circadian cycle – a natural psychological and physiological phenomenon and it’s pretty normal to experience this.

Similar to the moon influences the tides in the sea, the sun influences our circadian cycle. This consists of a 24 hour cycle governed by Earth’s rotation around the sun, during which nights and days loop, influencing our biological clock which in turn affect our behavior. In other words, the sun is very important in regulating our body, our sleep and our health!

So without affecting our eye health, how can we gain maximum benefits from the sun?

Why sun / natural light is your friend ?

Natural light not only plays a pivotal role in our mental and physical health but also in our behaviors, by inducing hormone production which has a direct relationship in the regulation of our energy and sleep cycle.

Morning light contains blue light and acts as a natural alarm clock by stopping melatonin production (the sleep hormone), thereby helping us to get out of bed. On the other side, evening light is filled with orange and red light, facilitating melatonin secretion and thereby, sending us into sleep. This explains why majority generally have more energy in the morning than late evening.

Natural light also increases the secretion of dopamine and serotonin (happy hormones) and there by affect our mood. Our eyes give a small signal to the portion of our brain called the hypothalamus when they perceive natural light, which in turn alerts the suprachiasmatic nucleus (SCN), also called our biological clock. Dopamine and Serotin (happy hormones) are then released throughout our body, which increases our overall sense of wellbeing. So when the sun comes out it’s completely normal to be in better mood.

Sun can cause irreversible damage to our eyes in long term even though it’s vital for the proper functioning of our body. Unprotected long sun exposure can lead to macular degeneration, early development of cataract and can cause discomforts such as redness, irritation and tearing.

Having said that, it is still recommended to reduce screen time and spend some time outdoors both for your mental and physical health. A simple thirty-minute walk is good for your eyes, legs, and mood! All you need to do is choose the correct sunglass providing ideal UV protection for every outing, however short.
