Daylight Saving Time, Summer Sun, and Your Mental Health: What NJ Residents Need to Know
By Dana Colthart, Clear Light Therapy | Bergen County & Monmouth County, NJ | Virtual Therapy Across New Jersey
Spring has arrived in New Jersey. The clocks have sprung forward, the days are getting longer, and warmer weather is on the horizon. For many people, this seasonal shift brings relief after a long winter. But for those living with OCD, anxiety, panic disorder, or depression, the transition from winter to spring and eventually into the heat of summer, can bring a surprising set of challenges.
At Clear Light Therapy, we work with clients throughout Bergen County, Monmouth County, and virtually across New Jersey, in towns like Englewood, Tenafly, Ridgewood, Rumson, Red Bank, Saddle River, Hoboken, and Montclair, to help them understand and manage how environmental and seasonal shifts affect their mental health. Whether you're navigating OCD, anxiety, panic attacks, eating disorder recovery, or seasonal depression, this post is for you.
Daylight Saving Time: More Than Just a Lost Hour of Sleep
Most of us treat the spring time change as a minor inconvenience, we lose an hour of sleep on a Sunday morning and move on. But for people with anxiety, OCD, or mood disorders, that one-hour shift can have a measurable ripple effect.
Researchers at Harvard Medical School have found that moving the clocks forward disrupts our circadian rhythms, the body's internal 24-hour cycle that regulates sleep, appetite, mood, and energy. The spring transition is particularly disruptive because it creates darker mornings, which reduces morning serotonin production, and lighter evenings, which suppresses melatonin and makes it harder to fall asleep at night. The result? Many people feel jet-lagged, groggy, and on edge for days or even weeks after the change.
Sleep neurologist Dr. Zhikui Wei at Jefferson Sleep Clinic explains that the lost hour doesn't just affect one night, the sleep debt can accumulate over weeks. And that accumulated sleep debt matters enormously for mental health. Research has consistently shown a direct link between sleep disturbances and higher rates of anxiety and depression, with clinical providers often reporting an uptick in symptoms among existing patients in the weeks following the spring time change.
For people with OCD or anxiety, this disrupted sleep can lower distress tolerance, making intrusive thoughts feel louder, compulsions harder to resist, and uncertainty more difficult to sit with. If you've noticed your OCD or anxiety feeling harder to manage this time of year, the clock change may be partly to blame and that's not weakness; it's biology.
What Helps: Adjusting Gradually
The good news is that you can buffer this effect. Sleep experts recommend adjusting your bedtime by 10 to 15 minutes earlier in the days leading up to the time change, rather than absorbing the full hour shift all at once. Cutting back on caffeine and alcohol in the days surrounding the change can also help, as both disrupt sleep architecture. And getting outside for morning sunlight, especially in the first few days after the clocks change, helps reset your circadian rhythm by signaling to your brain that the day has begun.
The Upside: More Sunlight Is Genuinely Good for Your Brain
Here's the genuinely hopeful part of this story: despite the short-term disruption of the time change, the longer days that come with spring and summer are meaningfully beneficial for mental health, particularly for people who have struggled with depression or Seasonal Affective Disorder (SAD) through the winter months.
Sunlight is the most powerful synchronizer of our circadian rhythms. When your eyes are exposed to natural light, your brain releases serotonin, the neurotransmitter most closely associated with mood stability, calm, and focus. Research from Brigham Young University found that days with more sunshine were associated with better mental health outcome more so than any other environmental factor, including rainfall or temperature. In fact, one study found that hospitalized patients with bipolar depression who stayed in sunlit rooms had shorter hospital stays than those in darker rooms.
Sunlight also drives vitamin D production in the skin. Vitamin D plays a surprising role in brain health, it supports the production of both dopamine and serotonin, and low levels have been consistently linked to higher rates of depression, anxiety, cognitive impairment, and poor sleep. For many New Jersey residents who spend long winters mostly indoors, spring sunlight is genuinely therapeutic.
A 2025 study even found that a meaningful reduction in sunlight exposure in a given month was associated with a nearly 7% increase in suicide rates, a finding that underscores just how important light is to our neurological and emotional regulation.
The takeaway: after a long NJ winter, getting outside in the spring sun isn't just pleasant. It's clinically meaningful.
OCD and Anxiety in the Spring: What Shifts With the Season
Spring brings more than longer days. For many people with OCD, the seasonal transition itself, the disrupted routine, the changing sleep schedule, the pressure to "feel good" now that the sun is out, can actually spike symptoms temporarily.
OCD and anxiety thrive on uncertainty, and transitions are full of it. A disrupted sleep schedule from the time change can lower your ability to tolerate intrusive thoughts without engaging in compulsions. The "spring energy" that everyone else seems to feel can make those struggling with OCD or anxiety feel confused or ashamed that they don't feel the same way, which can in turn fuel more rumination and reassurance-seeking.
This is a good moment to revisit your ERP (Exposure and Response Prevention) hierarchy and your ACT (Acceptance and Commitment Therapy) skills. At Clear Light Therapy, we use ERP to help clients resist compulsions even when their nervous system is louder than usual, and ACT to help them stay connected to their values even when intrusive thoughts feel more persistent. Seasonal disruptions are exactly the moments when these skills matter most.
Body Image, Warm Weather, and Eating Disorder Recovery
As the weather warms, something culturally predictable happens: bodies become more visible. Shorts, swimsuits, sleeveless tops. Social media fills with "summer body" messaging. For anyone in eating disorder recovery, whether navigating anorexia, bulimia, binge eating disorder, ARFID, or disordered eating patterns, this seasonal shift can feel jarring.
Warmer weather doesn't have to derail your recovery, but it does require intentional support. At Clear Light Therapy, we help clients in Bergen County and across New Jersey approach the season using a HAES-informed (Health at Every Size) framework that prioritizes self-compassion over body scrutiny. We encourage clients to notice when diet culture language enters their space, in conversations, on social media, in advertising and to practice the same radical honesty with themselves that they would offer a close friend.
If you notice that warmer weather is triggering an increase in restriction, compensatory behaviors, obsessive food thoughts, or body checking, this is exactly the kind of thing to bring to your therapist. You don't need to "white-knuckle" it through the season alone.
Heat, Anxiety, and Panic Attacks: Why Summer Can Feel Dangerous
Here is something that doesn't get talked about enough: summer heat can genuinely worsen anxiety and there are clear physiological reasons why.
When your body temperature rises in the heat, your heart rate increases, you may feel dizzy or short of breath, your palms may sweat, and you may feel a sudden wave of unease. Sound familiar? Those are also the symptoms of a panic attack. For people with anxiety disorders or panic disorder, the brain can misread the body's normal heat response as a signal of danger, triggering a real anxiety spike or even a full panic attack, even though what's happening is just your body trying to stay cool.
Research published in the journal Environment International found a nearly 8% increase in emergency department visits for mental health concerns on days with extreme heat. A South Korean study specifically found that even brief exposure to higher temperatures increased the risk of panic attacks. This isn't imagined, it's a documented physiological feedback loop: heat triggers physical sensations, the anxious brain interprets those sensations as threatening, adrenaline surges, and the symptoms intensify.
For those with health anxiety or a strong sensitivity to bodily sensations (which is common in OCD and panic disorder), New Jersey summers can be especially activating. High heat, humidity, and packed outdoor events can all push the nervous system toward its threshold.
CBT and DBT Skills That Help in the Heat
At Clear Light Therapy, we draw on CBT (Cognitive Behavioral Therapy) and DBT (Dialectical Behavior Therapy) skills to help clients navigate this. A few that are particularly useful in summer:
Cognitive restructuring: Learning to identify the thought "I'm having a panic attack" and examine it — "Is this heat, or is this actually dangerous?" This isn't avoidance; it's accuracy.
Interoceptive exposure (from ERP/CBT for panic): Deliberately practicing tolerating the physical sensations of heat in small doses, so your brain stops treating them as catastrophic.
TIPP skills from DBT: Temperature, Intense exercise, Paced breathing, and Progressive muscle relaxation. Notably, the "T" in TIPP, using cool water or a cold compress, is a direct tool for regulating a nervous system that has been dysregulated by heat.
Radical acceptance (DBT): Acknowledging that heat is uncomfortable without adding the story that it means something is wrong with you.
Less Sunlight in Winter Made Things Worse.. More Sunlight in Spring Can Make Things Better!
One of the most important things we tell clients who struggled through the winter is this: what you experienced wasn't just "in your head." The research is clear that reduced sunlight suppresses serotonin production and disrupts circadian rhythms in ways that genuinely worsen depression, anxiety, and OCD symptoms. The darkness of a New Jersey winter, especially the early sunsets after the fall clock change, has a measurable neurological effect.
This means that the return of longer days in spring is an actual biological gift. Morning sunlight exposure, outdoor walks, and simply being near windows during daylight hours all support serotonin regulation, vitamin D production, and circadian stability. You don't need to do anything elaborate. Even 10 to 15 minutes of morning sun on your face and arms several times a week can meaningfully support your mood.
For clients working through depression in therapy, we often recommend integrating more outdoor time as a behavioral activation strategy, a core CBT technique that uses action to shift mood, rather than waiting to feel better before acting.
