Love is a powerful emotion that can inspire us to great things. It can make us trust and open up in ways that would otherwise be difficult. It can make us feel like we have a personal cheerleader in our corner and that someone has our best interest at heart. It can also be a source of pain and suffering, particularly when it is unhealthy or unrequited. Throughout history, philosophers and religions have speculated about the nature of love. In the 20th century, psychology, sociology, and neuroscience have begun to study it as well.

In many cases, it’s difficult to define love, even for those who have experienced it. It is often said that “love is a feeling you can’t describe,” or that it’s a giddy feeling that takes over your body. However, researchers have identified some telltale signs that you may be in love:

1. When you’re in love, you feel happy all the time.

When you’re in love, you want to spend time with the person you care about more than anything else. You’re willing to put in extra effort and sacrifice for them. You are constantly thinking about them, dreaming of them, and wanting to be around them as much as possible. You might start to avoid other activities that you used to enjoy in order to spend more time with them. You might even feel a giddy excitement when you think about them.

2. You want to protect the person you’re in love with from harm.

When people are in love, they tend to treat their loved ones differently than others. They might be protective and a little possessive, and they might want to keep them close to them. They might not want to let anyone else see them with their partner, and they might be reluctant to talk about their relationship publicly.

3. You can’t imagine life without the person you’re in love with.

In a healthy love, the person you’re in love with understands your fears and needs and respects them. They listen to you and help you work through your problems. They support you emotionally and physically. They help you achieve your dreams. They share your sense of humor and values. They’re there for you in times of crisis and celebration. They’re your best friend.

4. You’re able to forgive them for their mistakes and mishaps.

In healthy relationships, feelings of love and affection are associated with the release of oxytocin, also known as the “love hormone.” Affectionate behavior like hugging and holding hands releases oxytocin, which encourages bonding, reduces pain, and creates a general feeling of calm. Affectionate behavior can even lower your blood pressure and improve your mood. However, in unhealthy relationships, feelings of love can be complicated by insecurity and a lack of trust. Unhealthy relationships can lead to anxiety and depression, and they can damage self-esteem.

The meaning of love is a complex and fascinating subject. Various emotions and behaviors are commonly considered to be loves, but the defining factor is the emotional attachment or sense of belonging. It is this connection and comfort that give us a sense of purpose in the world, helping us to survive and thrive as humans.
