20 Science-based Facts About Love

1. Love and lust: The difference lies in the eyes of the beholder.

You may think that your heart knows the best. However, love is not a precondition for sexual desire, and sexual desire may not always lead to love.

A study has shown that the pattern of eye gaze can reveal the difference between love and lust (sexual desire). As per the study, the eye gaze shifts based on the person’s goal—the feeling of love leads to more frequent eye fixations on the face than on the body, whereas in lust, the eye fixation is more profound on the body than on the face (1).

Yes, the eyes do reveal your intentions and interests.

2. Love acts like a drug.

Interestingly, the areas of the brain that are activated by these romantic feelings largely overlap the areas that are associated with reward, desire, addiction, and euphoric states. Romantic love and use of opioid drugsiXA category of painkillers that interact with opioid receptors in the body to relieve pain , such as cocaine, trigger similar regions in the brain, releasing oxytociniXThe hormone that also acts as a chemical messenger and regulates various body functions and human interactions and behavior , vasopressiniXA hormone and neurotransmitter involved in the electrolyte–water balance, social bonding, and stress response , and dopamineiXA chemical that transport messages among nerve cells and also acts as a hormone that induces happiness and motivation , which put one in a “feel-good” or “happy” state (2).

3. Hugging your partner can lead to less stress and a healthier heart.

Hugging a partner or spouse can lower blood pressure and increase oxytocin levels in premenopausal women (3). Oxytocin hormone is known to have anti-stress properties and promote healing and well-being (4).

Rachel Boulos, a blogger, describes the positive impact of hugging her husband on her mood. She explains, “When I am feeling moody, irritable, or just plain sad, my husband will say ‘do you need a 30-second hug?’ After 30 seconds (which is like an eternity in hug time), I notice that I physically and emotionally feel better (i).”

4. A loving relationship means a healthy heart.

Being in a relationship or being married has its perks. A study of 3.5 million people has revealed that people who are married have lower rates of cardiovascular diseases when compared with people who are single, divorced, or widowed (5). In individuals aged 50 years and below, marriage is associated with 12% lower odds of any vascular disease (5).

“My heart beats for you…” Do you say that to your partner often? Scientifically, you may not be wrong.

According to a study conducted by researchers at the University of California, lovers’ hearts beat at the same rate. The study revealed that the heart rate and respiration rate of couples who are in a romantic relationship synchronize when they sit facing each other for around three minutes (6), (7). Interestingly, when the pairs are mixed, no syncing is observed.

6. Love can reduce your pain.

Love can act as a painkiller. Surprised? Well, when people are in love, their moods change and also their experiences with pain.

Do you remember every aspect of your relationship—how it moved forward, and what the important milestones were?

A study has reported that committed couples remember their relationship history, including the things that happened during each stage of their relationship more accurately than those couples in a strained relationship (9). The study says that the couples in the second group often choose to misremember things to avoid disappointment.

8. Distance makes the heart grow fonder.

The study has revealed that long-distance relationships are not only successful, but also help in developing trust, fondness, and satisfaction between partners (10).

9. Couples start to look alike in appearance.

Opposites may not always attract. You may have noticed that some couples do look alike. Interestingly, a group of researchers from the University of Michigan found that couples grow to look more like each other after a certain period (around 25 years) (11). The happier the couple, the closer the similarity in their physical appearance.

When people say love and time can heal all wounds, they may not be wrong.

Researchers have observed an association between psychological distressiXUnpleasant and overwhelming feelings commonly triggered by mood disorders such as anxiety or depression and wound healing.

It starts with obsession and intense adoration (serotonin levels are high at this time) but then cements into a relationship or a more mature form of love (oxytocin levels are high at this time) (17).

16. Love and lust activate different regions in the brain.

Researchers believe that lust and love involve different intentions, goals, and interests. Now, brain imaging studies have made it possible to map out the regions of the brain that are responsible for love and lust.

A study reveals that love and lust activate different areas of the striatum (a part of the brain structure). The area activated by lust is the same area that is usually activated by pleasurable things, such as sex or food. On the other hand, the area activated by love is associated with reward or pleasure and is also the same region that is associated with drug addiction (18).

It can occur due to various factors, including the death of a loved one, divorce, breakup or physical separation, and betrayal or romantic rejection (22).

21. Lovesickness is also a real thing.

Being lovesick is also an illness with symptoms and remedies. Lovesickness happens in two conditions: when a person yearns for their love interest who has been separated and when a person starts seeing someone new. In both situations, the stress hormone cortisol is released, making the person feel sick. According to research, lovesickness is a disorder characterized by symptoms such as headaches, fever, palpitations, loss of appetite, and agitation (23). It is mainly cured when the romantic interest returns to the person or when they become comfortable with their new love interest.

As per Greek legends, the name rose is an anagram created by the Goddess of beauty, Aphrodite, who dedicated the flower to her son Eros, the God of love. To protect God’s frailty, Eros bribed the deity of silence, Harpocrates, with a rose. Since then, the rose has become a symbol of love, secrecy, and silence (24).
