Summer is reminiscent of many things: the smell of sunscreen, longer evenings, dedicated family time, vacations finally on the calendar, maybe even a wardrobe refresh.

There’s a particular kind of joy that settles in this time of year, a collective breath of excitement.

But for people living with Postural Orthostatic Tachycardia Syndrome (POTS), summer’s signature feature, heat, can turn that joy and excitement into something much harder to navigate.

POTS is a form of dysautonomia that disrupts the body’s ability to regulate blood flow when moving from lying down to standing.

Temperature dysregulation and heat intolerance are core symptoms in POTS.

Heat makes symptoms worse: blood vessels dilate, blood pressure drops, and symptoms like dizziness, fatigue, and heart palpitations intensify. What feels like a beautiful day to most can feel like an obstacle course to someone with POTS.

POTS affects an estimated 0.2 per cent to 1 per cent of the North American population, according to a 2020 NIH study; a figure that’s almost certainly undercounted, and one many researchers believe has grown significantly in the wake of COVID-19.

Roughly 75 per cent to 85 per cent of POTS diagnoses are female, and the average time from symptom onset to formal diagnosis is four to six years.

These individuals spend years researching their symptoms, becoming fluent in their own condition long before receiving a diagnosis.

Since launching its first-generation Embr Wave device, Embr has consistently heard from those with POTS looking for a solution for temperature intolerance and the symptoms that result.

Embr Wave’s temperature delivery system, providing immediate wearable cooling relief, maps directly to one of POTS’s most consistent symptoms, heat intolerance.

Embr’s implementation of Tempura, Embr’s app-based AI Assistant, has provided Embr with even more clarity on the impact Embr Wave can have in this statistically small population.

In the last 90 days, nearly 3 per cent of conversations with Tempura have touched on POTS. Relative to population prevalence, that’s a significant overrepresentation, confirming that individuals with POTS are actively seeking tools that are designed for their symptoms.

Embr Wave provides a model for how designing products for one use case, menopausal women managing hot flashes, can be found to have tremendous benefits for other populations.

The influx of advocacy by those with POTS led to a research study published this year that measured the improvement in Quality of Life factors when supported by thermoregulation wearables.

The product design by its nature, and how customers are using and talking about it, has had a snowball effect in the POTS community, amplifying awareness of a safe, always-available solution for this unmet need.

For someone with POTS, temperature isn’t a minor variable but a sizable trigger. Giving someone a way to manage temperature response hands them back a measure of control they didn’t have before.

Those in the Embr community living with POTS describe using their Wave devices both proactively and in-the-moment: some turn on their Wave’s cool-down signals before leaving the house or entering a crowded event, knowing what’s ahead.

Others use it reactively, when they feel their body beginning to respond poorly, and bring themselves back in balance.

Either way, Embr Wave provides its users with a sense of control around something they cannot control, their environment, allowing one to focus on and enjoy the moment.

No one should have to skip the places or events they love because their body can’t handle the heat. The goal is to help people stay in their lives fully, with less friction and more confidence in what their bodies can handle.

Women’s health startup Ovum has raised US$4m in seed funding to develop its AI health journal and expand research using women’s health data.

The round valued the Melbourne startup at US$18m.

Ovum plans to use the funding to develop its artificial intelligence technology and longitudinal datasets, which track health information over time to reveal changes and patterns.

The AI captures symptoms, lifestyle factors, biometric measurements, reproductive health stages, medication, appointments and medical reports.

It uses this information to identify health patterns and create summaries and questions for medical appointments.

Ovum previously raised US$1.7m in pre-seed funding in February 2025 before launching its health journal app in August that year.

Since then, the company says the app has grown by 30 per cent month on month and recorded more than 20,000 downloads.

It has captured 57,000 health data insights and hosted more than 107,000 AI health conversations involving women aged between 15 and 84.

Founder Dr Ariella Heffernan-Marks developed the idea while she was a third-year medical student experiencing chronic migraines and was told that her pain was caused by anxiety.

The company describes the resulting women’s health journal as combining technology and clinical research to make health information more actionable and equitable for women.

Heffernan-Marks said: “I’ve sat on both sides of the desk, as a patient and as a doctor, and that’s why this mission matters so much to me.

“For too long, women have had to navigate healthcare systems that were not designed around their lived experiences or backed by sufficient female health data. Ovum exists to help women better understand their bodies, advocate for themselves with confidence, and contribute to research that improves care for future generations.”

Private health insurer Medibank is an Ovum partner, alongside Fernwood Fitness, Sweat and Menopause Friendly Australia.

Australian Red Cross Lifeblood is also involved in a pilot examining productivity losses caused by women reducing their working hours or leaving employment for health reasons.

Earlier in 2026, Ovum launched clinical trials with St George Hospital and the Royal Hospital for Women to assess AI as a preventative health tool for women.

The research is examining how women currently manage their health, which digital tools they use and whether AI could support health confidence, self-advocacy and continuity of care.

Continuity of care means receiving connected and consistent support across different appointments, healthcare professionals and services.

The funding round was led by Admiralty Capital Group, with participation from Antler, Giant Leap, Aviron Investments, Foggy Valley Aotearoa, Brisbane Angels and Think & Grow.

Existing investor LaunchVic, which is due to merge with Breakthrough Victoria, also participated through its Alice Anderson Fund, which focuses on female founders.

Amanda Andriano, founding partner at Admiralty Capital Group, said the gender health gap was a problem that should not be tolerated.

She said: “Ovum combines mission, market timing and technical capability with an exceptional founder uniquely positioned to lead this movement, and we believe that creates the foundation for a company of global significance.”

Women who do strength training may have a lower risk of major cardiovascular disease, particularly alongside aerobic activity, a study suggests.

Cardiovascular disease is the leading cause of death worldwide. Aerobic activities such as brisk walking, jogging, cycling and swimming are already established ways to help reduce the risk.

Strength or resistance training, also known as RT, is less established as a prevention strategy. It makes muscles work against a force and can involve body weight, free weights, resistance bands or machines.

Current US guidelines recommend at least two days of strength training and 150 minutes of moderate-to-vigorous aerobic activity each week.

They also recommend limiting sedentary behaviour, including prolonged television viewing, which is considered an independent risk factor for cardiovascular disease.

Dr Tianyue Zhang, lead study author and scientist in the department of nutrition at the Harvard T.H. Chan School of Public Health, said: “Despite its established health benefits, RT is often overlooked as a prevention strategy for CVD, and its impact on CVD risk, especially in middle-aged and older women, remains understudied.

“A key question is, how much does it add beyond aerobic activity alone?”

Researchers analysed data from 117,025 women participating in the Nurses’ Health Study and Nurses’ Health Study II.

The two groups had average starting ages of 66.8 and 48.1 years respectively.

The women reported their resistance training every four years, with exercises involving the arms and legs recorded separately.

Time spent watching television was used as the main measure of sedentary behaviour.

The researchers examined exercise and television-viewing habits alongside the incidence of major cardiovascular disease.

Major cardiovascular events included fatal or non-fatal heart attacks, strokes, coronary artery bypass surgery and percutaneous coronary intervention.

Coronary artery bypass surgery redirects blood around narrowed or blocked heart arteries. Percutaneous coronary intervention uses a small balloon, often followed by a stent, to open a narrowed artery.

Higher levels of strength training were associated with a lower risk of major cardiovascular disease, particularly heart attacks.

No statistically significant link with stroke was found when resistance exercise was considered separately.

Women completing at least two hours of strength training a week had a 20 per cent lower risk of major cardiovascular disease and a 44 per cent lower risk of heart attack than those doing none.

Each additional hour a week was associated with a five per cent lower risk of major cardiovascular disease and a 14 per cent lower risk of heart attack.

The associations weakened somewhat after researchers accounted for body mass index and conditions including diabetes, high blood pressure and high cholesterol, but remained clear.

Body mass index, or BMI, compares weight with height and is commonly used to assess whether someone is within a healthy weight range.

Strength training was also linked to additional benefits among women who did aerobic activity.

Women completing at least two hours of strength training and 150 minutes of aerobic activity each week had a 45 per cent lower risk of heart attack than those reporting no physical activity.

Women who met recommendations for strength training, aerobic activity and reduced television viewing had the lowest risks of major cardiovascular disease, heart attack and stroke compared with those who met some or none of the recommendations.

Zhang said: “These findings suggest that, within an already active population, RT is associated with additional reductions in CVD risk above and beyond overall aerobic activity.

“Alongside aerobic activity and reductions in sedentary behaviour, RT may be an important component of public health strategies for cardiovascular prevention in women.”

The study relied on participants reporting their own resistance training, meaning the data may not always have been precise.

Researchers also noted the possible influence of unmeasured factors and the limited diversity of participants.

They were unable to fully separate the effects of the type of resistance training performed from the overall amount completed.

Dr Harlan M. Krumholz, professor at Yale School of Medicine, said: “We have long encouraged resistance training, and this study provides strong evidence to reinforce that message.

“It should be included in a well-rounded health routine to support function and longevity.”
