Why it is easier to fall in love in summer?
Summer is shorthand for the easy life. You’re more eager to love then. You want to walk around outside with somebody and drink beers on some rooftop and fall asleep in your summer dress on the subway because the heat is beating down on you and causing your eyes to close. Your eyelids just feel so and everything’s sticking to you, including love.
There's something about the heat that makes for some good lovin'. Yes, you both may be a sweaty mess, but the sunshine automatically puts a smile on your face and swing in your step. Besides, an ice cold glass of lemonade or iced tea and a spot of air conditioning can fix that. The days are long. The nights are short. And there's plenty of fun stuff to do to take advantage of the extended daylight and higher temperatures.
More sunlight means more melatonin and serotonin (chemicals in your brain that make you happy), so it's no surprise that people have more fun with each other during sunny weather. Plus, the warm weather means more opportunities for fun dates at flirty places like the beach, amusement park, picnic or barbecue.
