Why are Humans Afraid of the Dark?

 It is normal for people to be afraid of the dark. We have all probably had a childhood when we ran into our parent's room because we feared "the monster under our bed" - the dark corners in our room were hiding some boogeyman that would come and whisk us away, never to be seen again. Though we now know that this is completely normal, why does it happen?

The Uncertainty and the Unknown

Probably the most obvious reason is that in the dark, our senses are limited and we can't see threats coming at us. This makes us feel vulnerable and afraid because we don't know what might be lurking in the shadows. Additionally, our mind tries to make out what noises and shapes in the dark could be that cause fear, and it often interprets harmless images or sounds as threats. According to studies, being unable to see what is around us also raises our anxiety and stress levels.

Evolutionary Reasons

In the very early days of humans, our ancestors were more vulnerable at night due to the many predators which were active.  As a result, our brains have evolved to be especially sensitive to threats in the dark, and this can lead to fear and anxiety even in safe situations. This helped our ancestors a lot as they would be alert at night to any predators which may harm them.

Childhood Fears

Due to a lack of understanding of their surroundings, it is also common for children to be afraid of the dark, and these fears can often persist into adulthood. Furthermore, parents sometimes reinforce these fears through stories they tell their children for example, "Don't go out in the dark, there's a boogeyman that will get you." However, fears of the dark often fade as logical thinking and age develop.

Supernatural Associations

Many cultures believe in ghosts, spirits, demons and other entities which are more active at night than at day. This causes many people to be afraid of the dark because they believe that these entities might harm them. Additionally, horror movies often portray dark scenes where supernatural events take place.

Conclusion

In conclusion, our fear of the dark is a complex combination of evolutionary factors, childhood experiences, cultural beliefs, and our own personal experiences with darkness. They are completely natural and having them does not show that you are weak or scared easily - in fact, it means that you have inherited the survival skills of your early ancestors.
