The sun comes up earlier. You feel it before you see it. That low-grade buzz under your skin? It is not just happiness.
If you have bipolar disorder, summer is usually when things go sideways. Mania. Hypomania. The kind of energy that feels like a gift until you realize you haven’t slept in three days. Experts sometimes call this “summer mania.” It isn’t in the DSM-5, but every patient with seasonal patterns knows it by heart.
Up to a quarter of people with bipolar disorder battle Seasonal Affective Disorder (SAD). For most, sadness hits in the dark winter months. But for many with bipolar, the flip side is true. The light brings the chaos.
Why the Sun Breaks You
Nobody has a single, neat explanation for why this happens. But the science points to two things.
Your body clock. It is broken, or at least sensitive. Circadian rhythms govern when you sleep and when you wake. In bipolar brains, that rhythm is often out of sync. Then you add bright light.
Sunlight kills melatonin. The hormone that tells your body “it is time to sleep” gets suppressed. Summer gives us longer days. More light. Less sleep hormone. A recipe for disaster.
Ashley Lowe-Simmons, an LCSW in Ohio, puts it plainly: “The sun has the ability to boost our mind… if not properly treated, it can become easy to lose your head.”
When thoughts race, actions speed up. Control slips. And the risks aren’t just social.
The Physical Toll of Mania
We think of mood swings as mental. They are also physical.
High blood pressure. It spikes during manic episodes. Dr. Lowe-Simmons notes that this isn’t a temporary thing; it builds damage. Over time? Heart attack. Stroke. The engine overheats.
Substance use. Risk-taking comes with mania like a sidekick. Drinking, drugs. The body pays the price with liver damage, cancer risks, and lung issues. The mind pays with more episodes.
Then there is the collateral damage. Jobs. Partnerships. Reputations. People do things they wouldn’t dream of doing in December. In July? The consequences stick around long after the sun goes down.
6 Ways to Survive the Heat
You can’t turn off the sun. You can’t always prevent a manic shift. But you can lower the odds. Experts suggest sticking to the boring stuff. Boring saves lives.
1. Routine is Non-Negotiable
Summer loves chaos. Vacations. Kids out of school. Barbecues on Tuesday at 2 AM. This variety kills emotional stability.
Howard R. Weeks, a chief medical officer in Nevada, is blunt. Maintain a schedule. Sleep regular hours. Take your meds. Go to therapy. Do this every day.
Plan your life around your routine, not the other way around. If you want to enjoy the nice weather? Do it. But don’t pack your calendar so full that you can’t breathe. Use your phone alarms. Remind yourself to eat. Remind yourself to rest.
2. Sleep Hygiene or Nothing Else
Lack of sleep is the biggest trigger. Period.
Summer makes sleep hard. It is hot. It is light outside until midnight. You have to fight for your rest.
- Keep the room pitch black. Blackout curtains. Eye masks. If the sun sees your eyes, it will wake your brain.
- Kill the screens. Two hours before bed? Phone goes off. The blue light mimics daylight. Your body won’t believe it is night.
- Cool it down. Your core temperature drops when you sleep. Keep the bedroom chilly. A fan helps, especially with fireworks noise in the background.
Stick to wake and sleep times even if you are traveling. Your brain doesn’t care about your hotel room view.
3. Meds Are the Anchor
“Medication is one of the most… effective strategies,” says Lowe-Simmons.
Don’t get cocky when you feel good. Mood stabilizers work only when they are in your system. Going off them is asking for a crash. Withdrawal is brutal. Relapse is expensive.
Talk to your prescriber before July 1st. Adjust doses if needed. Don’t improvise with your chemistry.
4. Therapy Doesn’t Stop for Vacation
Seasons change triggers. Therapy helps you spot them.
Schedules change in summer. It is harder to get in. So get creative. Move the appointment to a different hour. Book a telehealth session.
Know ahead of time when your therapist goes on holiday. Get the coverage info. Who picks up the slack? Have that number ready. You do not wait for an emergency to find a new doctor.
5. Stress Less. Breathe More.
Summer is stressful. There are more plans. More people. More expectations.
Stress triggers mania. So you need exits.
Yoga. Meditation. A walk that is nowhere in particular. Block out ten minutes a day where you do nothing. Not scrolling. Not planning. Just existing.
“Create moments… when you are not busy.” – Ashley Lowe-Simmons
6. Skip the Bottle
Drugs and alcohol lower your inhibition. Mania lowers your inhibition. Together? It is a train wreck waiting to happen.
Summer activities often involve drinking. Concerts. Pool parties.
Tell your friends. Seriously. The people who get you need to know why you aren’t drinking the third beer. Find support. Stick with the crew that respects your boundary.
It is not about saying no to life. It is about surviving the season. The winter comes. The sun will drop. And you will still be there, if you handle the light correctly.
