Sleepless nights, overeating, a weakened immune system — the more common symptoms of stress are probably familiar to you. But stress can also trigger lesser-known side effects (both mental and physical) that you might not expect.
Here, Rosalind S. Dorlen, PsyD, a New Jersey-based, board-certified clinical psychologist and member of the psychiatry department at the Overlook Medical Center, shares some of the more surprising ways stress may manifest in your body.
1. ForgetfulnessIf you're feeling foggy or having a tough time focusing, stress may be the culprit, Dorlen says.
Indeed, stress and anxiety can hinder your attention and your ability to retrieve memories (or even make new ones), according to Harvard Health Publishing.
In fact, a November 2018 study in Neurology demonstrated that adults with higher levels of cortisol (the "stress hormone") exhibited impaired memory and lower brain volumes.
2. Skin Issues"Skin reactions like hives, viral exanthem (an eruptive skin rash), acne and cold sores seem to be an unfortunate example of collateral damage people experience under periods of extreme stress," Dorlen says.
Here's why: "Stress causes our bodies to make hormones like cortisol and epinephrine, which activate skin glands to produce oiliness, which can be a factor in acne and other skin-related conditions," she says.
What's more, during stressful times, we tend to neglect our usual self-care regimens (think: reduced sleep, skipping your face wash routine at bedtime, etc.) which can create or exacerbate existing skin vulnerabilities, Dorlen explains.
3. Reduced Sex DriveLost your libido? "Heightened or chronic stress can interfere with our body's hormone levels, producing greater amounts of cortisol and epinephrine, and the effect can reduce sexual interest or desire," Dorlen says.
Think about it: If your body is in a constant reactive state of flight-or-fight, fear or paralysis due to stress, these conditions aren't exactly conducive to sexy time.
Indeed, an October 2013 study in the Journal of Sexual Medicine discovered that high levels of chronic stress were correlated with less sexual arousal in women. The researchers concluded that psychological distraction and increased cortisol played a major role.
And the physical effects of stress can be negative for men, too. According to Dorlen, "the long-term effects of stress can narrow and restrict blood flow, which is one of a number of factors associated with erectile dysfunction."
Conversely, it's much easier to get in the mood when you're feeling loose and relaxed. "That may be why so many couples enjoy expanded sexual interest and participation when on vacation," Dorlen says.
4. Tight MusclesHave you suddenly noticed tension in your neck, back or shoulders? Stress may be the culprit.
Our bodies deal with stress by going into fight-or-flight mode, Dorlen explains, which means releasing hormones that ready our muscles to respond to whatever is threatening us. This can be helpful in the short term (think: running from a bear), but can cause issues if we're consistently under stress.
"Muscles tense up to protect themselves from injury during stressful conditions, so they may not get a chance to relax if the stress is continual," Dorlen says.
And to make matters worse, stress and anxiety can intensify your perception of muscular pain and decrease your ability to cope with it, according to the North American Spine Society.
5. AngerFeeling on edge? Irritability is a common symptom of chronic and prolonged stress, Dorlen says. This may have something to do with your body's chemical reaction to stress.
When your body releases chemicals in response to a perceived threat, your heart and breathing skyrocket to help you spring into action. This may have helped you flee a hungry predator back in the day, but today it might just leave you feeling tense, moody and even angry.
A January 2015 study in the American Heart Journal found that high levels of anger appeared to be linked to mental distress and an increased cardiovascular risk, while another November 2015 paper in The Journals of Gerontology: Series B discovered an association between anger and stressors in caregivers.
6. Gut ProblemsAnyone who's ever experienced a "nervous stomach" knows that stress can go straight to your gut.
Chronic stress can cause a whole range of GI complications, including stomachaches, constipation and diarrhea, according to Dorlen.
That's because your gut and central nervous system are in constant communication, per John Hopkins Medicine. In fact, they're so intimately connected that your gut is often referred to as your "second brain."
7. HeadachesFrom spilling coffee on your shirt to losing your keys and sitting in gridlock, everyday annoyances can be a headache — literally.
It goes back to that fight-or-flight response. When your body enters this state and produces hormones like adrenaline and cortisol, it causes vascular changes that prep your muscles to deal with the danger. But this chain of events can also give you a migraine or headache, according to the Cleveland Clinic.
What's more, during periods of high stress, many people experience tightness in their neck, jaw and shoulders — dubbed the "tension triangle" — which only worsens tension headaches, per the Cleveland Clinic.
