Love is a complex emotion that can be difficult to understand. However, there are some psychological facts about love that can help shed light on this topic.

In this article, we will discuss some of the most interesting and surprising psychological facts about love. We will also talk about how these facts can help you better understand your own love life!

Psychological Facts About Love

There is no one answer to the question of what love is. Everyone experiences it differently, and there are as many definitions of love as there are people in the world. But despite the differences in how we experience love, there are some psychological facts about it that remain consistent. 

#1 – Love is actually 3 feelings in 1

When we think of love, we often think of it as a single emotion. But the truth is, love is actually made up of three different emotions: lust, attraction, and attachment.

Lust is the physical desire we feel for someone. This is the feeling that drives us to want to have sex with someone. Attraction is the emotional connection we feel for someone. This is the feeling that makes us want to get to know someone better and spend time with them. Attachment is the emotional bond we feel for someone. This is the feeling that makes us want to be with someone even when we’re not physically attracted to them anymore.

These three emotions work together to create the feeling of love. But they don’t always last forever. Lust and attraction can fade over time, but attachment can last a lifetime.

#2 – Lust is different than love

Lust is the feeling that drives us to want to have sex with someone. It’s a physical attraction and it’s usually based on looks. Lust can fade over time, but it can also be rekindled. Love is different than lust.

Love is an emotional connection we feel for someone. It’s the feeling that makes us want to spend our lives with someone and have a family with them.

Lust is important in a relationship because it’s what keeps the physical flame alive. But it’s not love. And it’s possible to experience lust without love (and vice versa).

#3 – Attraction is based on obsession, not admiration

When we are attracted to someone, it is often because we have become obsessed with them. We can’t stop thinking about them, and they become the center of our world. This might not sound like a healthy way to start a relationship, but it is actually quite common.

In fact, research has shown that couples who report being “madly in love” at the beginning of their relationships are more likely to stay together long-term.

So if you find yourself thinking about someone all the time, it might be worth pursuing a relationship with them. Just be sure to take things slow and give each other some space occasionally!

#4 – Attachment isn’t exclusive to romance

We often think of attachment as something that happens in romantic relationships, but it can actually occur in any close relationship.

For example, you might feel attached to a close friend or family member. This type of attachment is known as “secure attachment.”

Secure attachment is characterized by feelings of trust, comfort, and warmth. So if you have a close relationship with someone that makes you feel secure, cherish it!

#5 – Being in love can decrease appetite

When you’re in love, you might not feel like eating. This is because being in love can decrease appetite.

It’s not entirely clear why this happens, but it might be due to the fact that being in love can release certain hormones (such as adrenaline and cortisol) that can suppress appetite.

So if you find yourself not feeling hungry when you’re in love, don’t worry – it’s perfectly normal.

#6 – Being in love changes you

When you’re in love, you might feel like you’ve changed. This is because being in love can change your behavior, thoughts, and feelings.

You might find yourself thinking about your partner all the time or behaving differently around them. These changes are normal and can be a sign that you’re in love.

If you’re in love, you might:

  • Think about your partner all the time
  • Be more concerned with your partner’s happiness than your own
  • Want to spend all your time with your partner
  • Feel a range of emotions, from happiness to jealousy

All of these changes are normal and can be a sign that you’re in love. If you’re worried about the changes you’re experiencing, talk to a trusted friend or family member. They can offer support and help you make sense of what you’re feeling.

#7 – Love can be a pain reliever

When you’re in love, your body releases oxytocin. Oxytocin is sometimes called the “cuddle hormone” or the “love hormone.” It has many different effects on your body, but one of its most important roles is reducing stress and pain.

If you’re feeling stressed, spending time with your partner can help you relax. Oxytocin can also help relieve pain. Studies have shown that oxytocin can reduce pain levels in people with conditions like migraines, fibromyalgia, and endometriosis.

#8 – Love is blind

The saying “love is blind” might have some truth to it. A study found that people in love were less likely to notice mistakes in their partner’s behavior.

Researchers think this happens because people in love see their partner in a positive light. They focus on their partner’s good qualities and overlook their flaws.

#9 – Love can make you sick

Being in love can literally make you sick. One study found that people in love were more likely to catch a cold than those who were not in love.

The researchers think this happens because being in love can weaken your immune system. When you’re in love, your body produces fewer cytokines. Cytokines are proteins that help fight off infections.

#10 – Being grateful can improve relationships

If you want to improve your relationship, try being grateful. Couples who express gratitude towards each other feel more connected and closer to each other.

So next time your partner does something nice for you, be sure to say thank you!

#11 – It takes just one-fifth of a second to fall in love

When you see someone you’re attracted to, your brain releases a cocktail of chemicals, including dopamine, adrenaline, and serotonin. This happens in just one-fifth of a second!

That first impression is everything when it comes to love.

So if you’re on a date and things seem to be going well, there’s a good chance you’re already head over heels!

#12 – Love is similar to being high

When you’re in love, your brain releases the same chemicals as when you’re high on cocaine.

These chemicals include dopamine and norepinephrine, which are responsible for the giddy feeling you get when you’re falling in love.

So if you’ve ever felt like being in love is similar to being high, you’re not wrong!

#13 – The brain falls in love, not the heart

It’s actually the brain that falls in love, not the heart.

When you meet someone and feel attracted to them, it’s your brain releasing chemicals that create those feelings.

So next time you tell someone you’re head over heels for them, remember that it’s your brain you should thank!

#14 – Love makes you dumb

When you’re in love, your brain releases oxytocin, which is also known as the “cuddle hormone”.

This hormone has been linked to making people feel bonded and connected to others.

But it also has been shown to reduce stress and anxiety levels.

So if you ever find yourself feeling a bit frazzled, just cuddle up to your loved one and let the oxytocin do its job!

#15 – Love does hurt

Although love is often associated with happy and positive feelings, it can also be quite painful.

In fact, studies have shown that love and physical pain actually share the same neural pathways in the brain!

So if you’ve ever been heartbroken, you can literally say that your ex broke your heart.

But on the bright side, this pain does eventually go away and can even make us stronger and more resilient in the long run.

So if you’re going through a tough break-up, just remember that it won’t last forever and you will come out of it stronger than before.

#16 – The love hormone is two-faced

Oxytocin is often referred to as the “love hormone” because it plays a role in bonding and attachment.

It’s released when we hug, kiss, or have sex with someone we love and it makes us feel all warm and fuzzy inside.

But oxytocin can also have a dark side.

It’s been shown to increase jealousy and envy and can even make people more prone to violence.

So while oxytocin might make you feel all lovey-dovey towards your partner, it can also make you more territorial and protective of them.

That’s why it’s important to be aware of the different sides of this hormone and not let it control your relationships.

#17 – Couples’ heart rates start to synchronize when they fall in love

This phenomenon is known as “entrainment” and it occurs when two people are deeply attracted to each other.

When entrainment happens, it means that the two people are physically and emotionally in sync with each other.

Entrainment is thought to be one of the reasons why couples who are in love often say that they feel like they “get each other.”


Love is one of the most complex and mysterious emotions we experience. It can be hard to define, but we all know it when we feel it.
