There’s a scientific reason for this seasonal spike in your libido.
Science says seasonal changes can influence our libido. When winter rolls in, hormones fluctuate and circadian rhythms shift in ways that stoke our desire for intimacy
Sex may permeate our popular culture, but conversations about it are still associated with stigma and shame in Indian households. As a result, most individuals dealing with sexual health issues or trying to find information about sex often resort to unverified online sources or follow the unscientific advice of their friends. To address the widespread misinformation about sex, News18.com is running this weekly sex column, titled ‘Let’s Talk Sex’. We hope to initiate conversations about sex through this column and address sexual health issues with scientific insight and nuance
In this article, we will explain why winter boosts your libido & the role of hormones during this seasonal spike.
The days are getting shorter, the nights longer, and cold weather is on the horizon. As the seasonal change hits, you may notice something else rising with the dropping temperatures – your sex drive. Don’t worry, you’re not alone. Turns out, science says seasonal changes can influence our libido. When winter rolls in, hormones fluctuate and circadian rhythms shift in ways that stoke our desire for intimacy.
There’s a scientific reason for this seasonal spike in your libido.
- Hormone changes: As the days get shorter in the fall and winter, our body produces more melatonin, the hormone that makes us sleepy. But it also boosts testosterone, the hormone responsible for sex drive in both men and women. More testosterone means more sexual thoughts and arousal. The colder temps also cause a rise in oxytocin, the “love hormone” that promotes feelings of closeness and intimacy with our partners. Melatonin also boosts dopamine, the feel-good hormone that boosts libido and arousal. For women, melatonin may also increase estrogen levels which in turn spikes libido.
- Increased opportunity: The shorter, colder days of winter mean more time spent indoors and in bed. With extra time on our hands, our thoughts often turn to intimacy and physical connection. The holidays also provide opportunities for romance, with time off work and fewer scheduled commitments. Cuddling up under the covers also releases oxytocin, the “love hormone” that boosts feelings of closeness and arousal.
- Psychological factors: The winter season often sparks nostalgia for cosy memories with loved ones. This sense of warmth and togetherness naturally translates into a desire for sexual intimacy. Some research also shows that we tend to crave high-calorie, high-fat comfort foods more in winter. And since food and sex activate similar pleasure centres in the brain, our hunger for decadent foods may feed our hunger for sensual pleasure as well.
How Changes in Sunlight Impact Sex Hormones?
The changing of the seasons brings more than just a shift in the weather—your hormones are changing too.
Less Sun Means Less Serotonin: Serotonin is the “feel-good” hormone that boosts our mood and arousal. Studies show serotonin levels peak when you’re exposed to bright light and drop when there’s less sunlight. During winter, less sun exposure causes serotonin levels to bottom out, which can undermine our sex drive and desire. To boost mood and arousal, spend time near bright light sources, like sunny windows. You can also consider light therapy, which exposes you to artificial bright light to increase serotonin. Exercise is another great way to boost serotonin and your libido.
More Darkness Releases Melatonin: As the days shorten, our body produces more melatonin, the hormone that regulates our sleep-wake cycle. While melatonin is great for helping you sleep at night, too much of it during the day can make you drowsy, depressed, and disinterested in sex. To curb excess melatonin, expose yourself to bright light as soon as you wake up. Open the blinds or turn on the lights—this helps signal to your body that it’s time to feel alert and awake. Getting enough rest is also key to regulating your hormones and boosting your sex drive.
What is Seasonal Affective Disorder (SAD) and Increased Desire?
Seasonal Affective Disorder (SAD) is a type of depression related to changes in seasons, typically caused by a lack of natural sunlight in fall and winter. As the days get shorter in winter, your body may produce more melatonin, a hormone that makes you sleepy, and less serotonin, a mood-regulating neurotransmitter. For some, this can trigger symptoms of depression like low energy, increased sleep, weight gain, and irritability.
Interestingly, for others, the winter blahs can have the opposite effect on libido. The same fluctuations in hormones and neurotransmitters that lead to SAD in some may actually increase sexual desire in others. The lack of natural light exposure in winter causes your body to seek out pleasurable activities as a way to boost mood and motivation. Engaging in sex leads to the release of dopamine, endorphins and oxytocin—all feel-good hormones that act as natural mood boosters.
Foods That May Help Increase Your Sex Drive in Winters
When the temperatures drop, your libido may spike. Some foods are particularly well-suited to boosting your sex drive during winter.
- Spicy foods: Foods with a kick of spice like chilli peppers, curry dishes, and hot sauce can increase your circulation and raise your body temperature. Capsaicin, the compound that gives spicy food its heat, releases endorphins that pump up arousal and pleasure centres in the brain.
- Dark chocolate: Dark chocolate contains compounds like phenylethylamine that release dopamine, the “pleasure” neurotransmitter in your brain. Just a few bites of 70 per cent cocoa or higher dark chocolate can improve your mood and ignite your desire.
- Oysters: Oysters have been considered an aphrodisiac for centuries. They are high in zinc, which helps boost testosterone and healthy sperm production in men, and also contain amino acids that trigger increased feelings of arousal and pleasure for both genders.
- Pomegranates: The juicy seeds of pomegranates have potent antioxidants that support healthy blood flow, essential for arousal and sexual satisfaction. Pomegranate juice in particular has been shown to have a Viagra-like effect on circulation.
So, if you find your libido seems to spike in the winter months, you can blame it on the seasons—or rather, the effect of the seasons on your body’s chemistry and natural drive for pleasure and closeness. While SAD may get some down, for others the winter blahs are a perfect excuse to stay in, get cosy and ignite your passion under the covers. The long winter nights offer plenty of time to reconnect physically and emotionally with your partner. The science of sex is hot – even when the weather’s not! So, consider this your official notice: winter’s coming, and so is your sex drive.
