Science Explains: Five Key Chemical Changes in the Body When Falling in Love

Kathmandu. It is said that love is blind. But science says that love is not blind; rather, it is a complex chemical process occurring inside the body.

When we fall in love with someone, changes occur in our brain and body that transform our behavior overnight.

Based on research conducted by renowned biological anthropologist Dr. Helen Fisher and Stanford neurologists, here are the five main changes that occur in the body upon falling in love:

1. Explosion of 'Happy Hormones' in the Brain

The reward system in the brain becomes active upon falling in love. This releases a hormone called dopamine, also known as the 'feel good' hormone. According to scientists, the effect of dopamine in love is similar to that of narcotics or drugs. This is why people want to meet and spend time with their partner repeatedly, as the brain seeks to experience that pleasure again and again.

2. Increased Heart Rate and the Function of Natural Painkillers

When you see your beloved, your heart rate increases, your hands become cold, or you feel a flutter in your stomach. This is all the magic of the adrenaline hormone. Interestingly, research shows that the body's natural painkiller system becomes active during love, which reduces the sensation of physical pain or injury.

3. The Reason Behind Loss of Appetite and Sleep

'Losing appetite and thirst when in love' is not just limited to songs and poetry. Scientifically, in the initial stages of love, the level of cortisol in the body increases, which creates mild stress and reduces sleep. Furthermore, the decrease in serotonin levels causes a person's focus to be solely on their partner, leading to less interest in food and sleep.

4. The Cuddle Hormone and Unbreakable Trust

As the relationship progresses and intimacy increases, a hormone called oxytocin is released in the body. This is also known as the cuddle hormone or the chemical of attachment. It creates deep trust between two individuals and makes them caring towards each other. This hormone is the main basis for a long-lasting relationship.

5. Obsession with a Single Person

According to scientists, in the initial phase of love, the level of serotonin in a person's brain is as low as that found in patients with OCD (Obsessive-Compulsive Disorder). That is why, even if a person wants to, they cannot remove the memory of their partner from their mind. The part of the brain responsible for memory and repetition becomes so active that the same person is remembered 24 hours a day.

Love is not just an emotion; it is a beautiful balance of nature. The next time you feel your behavior is slightly different, understand that your body is giving you a signal of love.
