Summer on the South Shore Carries Health Risks Most Patients Do Not Think About
June arrives on the South Shore the way it always does — the harbor fills up, the beaches draw their first crowds, and summer feels like a break from health concerns. It isn't. Ticks, heat, UV exposure, and chronic conditions drift quietly at work all season long.

June arrives on the South Shore the way it always does: the harbor fills up, the trail systems get busy, the beaches at Humarock and Nantasket draw their first serious crowds, and the rhythm of life shifts toward longer days and fewer appointments. For many patients, summer feels like a natural break from health concerns. The air is warm, energy is up, and the greater preoccupations of a New England winter feel far away.
It is also, as it turns out, a season that carries a specific and underappreciated set of health risks. Some of them are well known but routinely underestimated. Others are quietly worsened by the behaviors summer encourages. And most of them are addressable with the right information and an established relationship with a physician who knows your baseline.
At Concierge Medicine of South Shore, Dr. Maria Clarinda Buencamino-Francisco, MD, works with patients across Hingham, Norwell, Scituate, Marshfield, Cohasset, and surrounding communities to make preventive care a year-round practice rather than a January resolution. Summer is one of the seasons where that relationship matters most.
Ticks: The South Shore's Most Consistent Summer Risk
No summer health conversation in Massachusetts is complete without addressing tick-borne illness, and no conversation about ticks in this state should be brief. The South Shore sits squarely within one of the highest Lyme disease burden regions in the country.
The Massachusetts Department of Public Health reported 8,842 probable cases of Lyme disease in the state in 2024. That is a documented figure, representing only the cases formally reported through surveillance systems. The CDC estimates that approximately 476,000 people may be diagnosed and treated for Lyme disease each year in the United States, a number substantially higher than what routine national surveillance captures.
Lyme disease is the most visible tick-borne concern, but it is not the only one. Massachusetts also tracks babesiosis, anaplasmosis, and Borrelia miyamotoi, all transmitted by the same black-legged tick that carries Lyme. Co-infections complicate presentation and treatment.
What most patients do not realize is that tick exposure on the South Shore is not limited to deep woods hiking. Ticks are active in lawn edges, garden beds, stone walls, and the scrubby transition zones between maintained yards and natural vegetation. They are present on the beach path, in the neighborhood park, and along the rail trail. The Deer Island Conservation Area, the Blue Hills Reservation, and any green space in Plymouth or Duxbury carry meaningful tick populations through late fall.
Effective prevention comes down to a few consistent habits:
Wear light-colored clothing that covers the legs and ankles when in grassy or wooded terrain
Apply EPA-registered repellent containing DEET, picaridin, or permethrin to clothing
Perform a full-body tick check after outdoor activity, paying particular attention to the scalp, behind the knees, and groin
Shower within two hours of coming indoors
Check pets before they enter the house
If you find an attached tick, remove it with fine-tipped tweezers and note the date. Single-dose doxycycline prophylaxis may be appropriate in certain cases, which is a conversation worth having with your physician promptly rather than waiting to see if symptoms develop. Early Lyme disease is highly treatable. Later-stage Lyme disease is not.
Heat, Hydration, and the Cardiovascular System
The South Shore's summer climate is more demanding than many residents account for. Coastal humidity in July and August can push apparent temperatures well above the thermometer reading, and the same outdoor activities that feel manageable in May become physiologically taxing by mid-July.
More than 65,000 people in the United States end up in emergency rooms each summer with heat-related illnesses. Heat exhaustion and heat stroke exist on a continuum, and the transition between them can happen faster than people expect, particularly in patients who are dehydrated, on certain medications, or managing underlying cardiovascular or metabolic conditions.
Heat can worsen heart failure and precipitate acute coronary syndrome, arrhythmias, and stroke, and certain medications commonly prescribed for cardiovascular disease may increase heat sensitivity. This is a detail that rarely comes up in the rushed context of a conventional primary care visit, but it matters considerably for patients who plan to be physically active outdoors from June through September.
Dehydration compounds every heat-related risk. The symptoms of mild to moderate dehydration, including fatigue, reduced concentration, headache, and elevated heart rate, are easy to attribute to other causes and, therefore, easy to ignore. Older adults are particularly vulnerable because the sensation of thirst becomes a less reliable indicator of fluid deficit with age.
Practical guidance for summer hydration and heat safety:
Drink water consistently throughout the day rather than responding to thirst, which lags behind actual fluid need
Schedule outdoor exercise for early morning or evening when possible
Know which medications you take that may affect heat tolerance, including diuretics, beta-blockers, and antihistamines, and discuss summer activity plans with your physician
Recognize the warning signs of heat exhaustion: heavy sweating, cool and pale skin, weakness, nausea, and a rapid weak pulse
Treat heat stroke, which involves hot, dry skin, confusion, and loss of consciousness, as a medical emergency
Skin Cancer: New England's Underappreciated Risk
There is a persistent misconception that skin cancer risk is primarily a concern for people who live in southern or consistently sunny climates. The data on Massachusetts says otherwise.
New England, including Massachusetts, has some of the highest rates of skin cancer in the country, a pattern driven in part by regional demographics and in part by a tendency among New Englanders to underestimate UV exposure on cloudy days, since clouds do not fully block the sun's harmful ultraviolet rays.
Melanoma accounts for only about 1 percent of skin cancers but causes the large majority of skin cancer deaths, with approximately 8,510 expected deaths in the United States in 2026. The survival rate for melanoma caught at a localized stage is dramatically higher than for disease caught after it has spread. Regular daily use of an SPF 15 or higher sunscreen reduces the risk of developing melanoma by 50 percent.
For South Shore residents spending significant time on the water, sun exposure is cumulative and often underestimated. Reflection off the water amplifies UV intensity. Time on a boat, at the beach, or working in the yard adds up over the course of a season in ways that a single day of sun protection does not fully address.
The role of primary care in skin cancer prevention is not limited to referrals. A physician who sees you regularly is well positioned to notice changes in existing lesions, prompt a dermatology referral at the appropriate interval, and ensure annual skin checks are part of your preventive framework rather than an afterthought.
Chronic Conditions Do Not Take a Summer Break
One of the more consequential patterns in preventive medicine is what happens to chronic illness management during summer. Schedules change, routine breaks down, and patients who have been diligently managing blood pressure, blood sugar, sleep, or other conditions find that summer's disruptions quietly erode the habits that were keeping those conditions stable.
Several specific dynamics are worth naming:
Migraine triggers multiply in summer. Dehydration, heat, disrupted sleep schedules, alcohol, and intense light are all established migraine triggers that concentrate in the summer months. Patients with a history of migraines who are not already working with a physician on a prevention strategy often find July and August to be their worst months of the year.
Travel disrupts medication and monitoring routines. Whether the trip is a week on the Cape or a longer international itinerary, travel creates gaps in medication adherence, missed monitoring appointments, and access challenges when something unexpected happens.
Sleep quality tends to deteriorate. Longer days shift circadian rhythms, heat disrupts sleep architecture, and the social calendar of summer often compresses the hours available for adequate rest. Patients managing cardiovascular disease, metabolic conditions, or mood disorders are all affected by reduced sleep quality in ways that can take weeks to manifest clinically.
Alcohol consumption increases. Summer social activity is associated with higher alcohol intake for many adults, which has downstream effects on blood pressure, sleep, liver function, and weight.
What a Proactive Summer Visit Looks Like
For patients at Concierge Medicine of South Shore, a summer check-in is not about waiting for a problem to develop. It is an opportunity to review any medication adjustments relevant to summer activity, assess hydration and cardiovascular status, address any tick exposures or accumulated skin changes, and ensure the management of any chronic conditions remains steady during a period when routine is most easily disrupted.
Dr. Buencamino-Francisco's practice is structured around the kind of time and continuity that make those conversations possible. Same-day and next-day appointments are available. To schedule a visit, call 781-795-9980 or visit conciergemedicineofsouthshore.com.
The Season Is Short. The Consequences of Overlooking It Are Not.
Summer on the South Shore passes quickly. From the first warm weekend in May to the last boats coming out of the harbor in October, the window is narrower than it feels in June. The health risks it carries, whether a Lyme infection that goes untreated for weeks, a skin lesion that gets checked too late, or a chronic condition that drifts out of control during a busy August, do not resolve on their own when the weather changes.
The patients who navigate summer well are the ones who stay connected to their care. A physician who knows you, tracks your baseline, and is available when something comes up is the difference between a season that is genuinely good for your health and one that quietly costs you.
