Ice cold disasters that shook the planet
Women smell better to men when they have high estrogen and low progesterone levels (indicating high fertility).
Not only are we attracted to other people’s smells on an individual basis, but some people’s smells are more attractive than others in general, too.
If people are healthy, they will generally smell better too.
It’s been shown that men who have a diet high in fresh produce smell more attractive to women.
Men rate women’s voices as more attractive when the women's progesterone levels were low and estrogen levels were high.
When women are ovulating, they are generally more attracted to men with wider jaws.
Our hormonal balances may play a bigger role than we think in who we become attracted to.
When you're attracted to another person, your brain releases dopamine, and oxytocin is produced, and your serotonin levels increase.
These "feel good chemicals" are what make us feel good around someone, inducing feelings of safety, warmth, and comfort.
Putting positive characteristics against someone’s photograph makes them appear better looking to other people.
Kindness makes people more attractive, which makes a lot of sense. It makes people more likable.
Attraction is also driven by the release of serotonin, which is the happy hormone. Hugging and sexual contact releases oxytocin, the love hormone.
Another chemical at play when we’re attracted to someone is norepinephrine, which together with dopamine makes us feel giddy.
It makes sense that this would be one of the most favored characteristics in a mate when we consider how it implies sharing and looking after one another.
Just before women start ovulating, they are more attracted to men with lower voices.
Not only are we attracted to people who are a little different from us so that our offspring benefit from genetic variability, but because they may just make up for what we don’t have (for example, maybe they're great at cooking and we're not).
In general though, humans don’t have the strongest sense of smell, so kissing means a lot from a psychological point of view.
We are attracted to people who have different immune responses to us and kissing allows us to get a sense of this.

Health makes us attractive to other people more than nearly any other factor, and the signals which communicate health are what make us seem attractive to others.

In men, attractiveness is perceived (in part) positively by masculinity, symmetry, and averageness, and negatively by adiposity (being overweight or obese).
Fertility can affect how women’s voices sound too.
While we tend to associate testosterone with men and estrogen with women, they both play a role in all genders and testosterone increases libido for everyone.
In women, attractiveness is affected positively by femininity and negatively by adiposity.
For example, men with higher levels of testosterone may be attracted to women with more feminine faces (i.e. big eyes, high eyebrows, and thin jawlines).
Attraction is generally increased by spending a lot of time with someone and physical touch (when it is welcome, of course) also tends to speed up the process.
A possible evolutionary reason for this is that having a lower voice may indicate that someone was bigger (and stronger) and may have been better able to survive in the wild.
Understandably, we pay a lot of attention to attractiveness in our society. It's pretty biological, after all. Indeed, common signals of attractiveness are signs of health and resistance to disease that display themselves as bilateral facial symmetry, large bright pupils, full lips, youthful skin, and melanin-rich hair. Would you have figured all that?
