When we think of wellness, most of us picture exercise, nutrition, and perhaps mindfulness. But there’s another powerful tool that’s been quietly gaining attention: sauna therapy. Once seen as a cultural tradition in Nordic countries, regular sauna sessions are now recognized by scientists as a potent ally for healthy aging.

Sauna Therapy and Longevity: How Heat Transforms Your Heart and Brain Health

Emerging research shows that heat therapy can improve blood flow, enhance endothelial function, and even reduce the risk of dementia. Let’s dive into the science of why a simple sweat might hold the key to living longer, healthier, and happier.

When you step into a hot sauna, your body undergoes physiological changes similar to moderate exercise. Core body temperature rises, your heart rate increases, and your blood vessels widen through vasodilation, allowing more oxygen-rich blood to circulate.

According to a 2018 study published in Mayo Clinic Proceedings, these responses mimic a cardiovascular workout and may explain why frequent sauna use is linked to lower rates of heart disease and stroke (Laukkanen et al., 2018).

In other words: a sauna isn’t just relaxation—it’s cardio for your blood vessels.

Cardiovascular Benefits: Protecting the Heart Through Heat

Heart health is at the center of longevity, and sauna therapy offers profound benefits. Studies have shown that regular sessions improve endothelial function – the ability of blood vessels to relax and contract effectively. Poor endothelial health is one of the earliest warning signs of cardiovascular disease (Tinken et al., 2010).

Additionally, frequent sauna use reduces blood pressure and supports healthy circulation. A landmark 20-year Finnish study revealed that men who used the sauna 4–7 times per week had a 50% lower risk of fatal cardiovascular events compared to those who only went once a week (Laukkanen et al., 2015).

That means your sauna habit could be as protective as exercise when it comes to heart health…powerful!

Cognitive Benefits: From Blood Flow to Dementia Prevention

It’s not just your heart that benefits from heat therapy—your brain does too. Increased blood flow from sauna use improves oxygen and nutrient delivery to brain tissue, which supports memory and concentration.

More strikingly, a large-scale study found that frequent sauna use reduced the risk of developing dementia and Alzheimer’s disease by up to 66% (Laukkanen et al., 2017). The researchers attribute this protective effect to improved vascular health and reductions in chronic inflammation—two key drivers of cognitive decline.

So, when you step into the sauna, you may also be safeguarding your long-term brain health.

Mood, Stress, and Antidepressant Effects

Beyond heart and brain health, sauna bathing also improves mood. Increased vasodilation and circulation trigger the release of endorphins and heat-shock proteins, both of which play a role in stress resilience.

Clinical evidence suggests that sauna therapy can reduce symptoms of depression and improve overall well-being. A 2016 randomized clinical trial published in JAMA Psychiatry found that whole-body hyperthermia had significant antidepressant effects, with many participants reporting improvements lasting for weeks (Janssen et al., 2016).

The “post-sauna glow” isn’t just psychological—it’s a physiological reset for your nervous system.

How Often Should You Use Sauna Therapy?

Researchers suggest that consistency is key. Benefits on endothelial function, cardiovascular health, and cognition are strongest with 3–5 sessions per week, lasting 15–20 minutes each at 80–90°C.

Unlike medications, there’s no prescription needed—just a towel, hydration, and a willingness to sweat.

The word stress tends to be associated with a negative connotation, as something bad for your health or an unwanted component of life. For many, it is viewed as a necessary and unavoidable consequence of a busy life. In reality, stress is neither good nor bad. It is not an inevitable part of life for all.

Stress is generally defined as a psychological and/or physiological reaction to a perceived threat. There is a great variability on how people perceive the same or similar events, generating unique individual perceptions of threat. Stress can be experienced as a good thing if it is viewed as a challenge or excitement, raising motivation, enhancing goal-oriented behaviour and promoting satisfaction. This “good stress”, or “eustress” as described by psychologists, is experienced when there is no perceived presence of threat, such as going on a roller-coster or receiving a promotion. This is the type of stress that heightens our sense of arousal and makes us feel fully alive. It is acute and the body returns to its homeostasis once the stressor is gone.

In contrast, chronic stress is an ongoing experience that makes us feel unable to cope and escape in the presence of continued stressors, resulting in long term harmful physical and emotional effects. Even persistent good stress can turn into bad stress since the adaptive stress responses are triggered the same way, unless you are able to shift perception and perspective, and have developed a resilient attitude towards stressful events in your world. Ongoing uncontrolled stress leads to “distress” as it becomes harmful to the body, which can lead to “stress-related illnesses”, such as migraines, digestive disorders, skin issues, etc.

Chronic stress without coping mechanisms, down time or lifestyle balance can lead to burnout and serious health consequences. No time for life, no escape activities such as hobbies or vacation, sleep and rest deprivation, or no access to supporting resources can compound the effects of stress. Cortisol, the stress hormone, has been declared “public health enemy number one” as its build up in the body lowers the immune system, causes weight gain, generates digestive disorders, increases blood pressure, leads to heart disease, affects mental health, and reduces life expectancy.

In the film “Stress: The Portrait of a Killer”, jointly produced by National Geographic Society and Stanford University, award-winning neurobiologist Robert Sapolsky stated “stress is not a state of mind… it’s measurable and dangerous, and humans can’t seem to find their off-switch.” Stress has become an individual addiction, representing a serious health crisis in society.

If you feel that stress is overwhelming your life and impacting your health and happiness, it is time to take inner control to reach balance and wellbeing. Among common approaches to alleviate or manage stress, such as meditation, yoga, breathing training, relaxation techniques, mindfulness training, social connections and time in nature, it is important to reflect on how you perceive threats, shift perspectives about life, understand what is ultimately important and be deliberate in recalibrating the only factor that is within your control: you.

According to the American Psychology Association, 75% of adults continue to experience high levels of stress and many people report increasing levels compared to previous years. Stress is an important health concern and is common in many countries and in various dimensions of our lives, from work to relationships.

Stress is often considered a silent killer due to its adverse effects on physical and mental health. Since it is a common occurrence and it is present in many areas of our lives, it can manifest in physical symptoms such as headaches, back pain or digestive disturbances, or interfere with sleep and our ability to cope with daily activities and challenges. Workplace stress is on the rise impacting both quality of life and economic costs.

The American Institute of Stress provides a definition of stress as a “condition or feeling experienced when a person perceives that demands exceed the personal and social resources the individual is able to mobilize.” Feelings of strain, pressure, helplessness and inability to keep up or cope are commonly described aspects of stress.

Considering that stress related symptoms are the cause of 75% of visits to the doctor and that stress is the primary cause of 60% of all illnesses, it seriously increases cardiovascular risk and stroke. High cortisol levels can also impact memory, concentration, clear thinking and decision-making.

The first step in addressing stress is identifying and managing the cause, whether it is an event (moving, for example), a skill (such as time management) or an emotion (e.g., anger). There are many strategies that can be adopted to cope with tension and reduce stress, from breathing techniques to massage, depending on individual needs and preferences. Below is a short list of simple steps to help you reduce stress.

  • write a stress journal: writing can bring relief of tension and can help identify triggers and trends;
  • take a nap: it can reverse the effects of poor sleep, protect the immune system and help feel better;
  • laugh more: it reduces stress and releases endorphins, promoting better health;
  • manage anger: let go, look at the big picture and be grateful; there is a correlation between anger and premature death;
  • use your support network: family, friends and faith based resources can provide support and increase your wellbeing;
  • eat foods that support health and good mood: fruits, beans, fish, whole grains, nuts, dark leafy greens, vegetables, etc.;
  • drink water: it can help with mood and energy; dehydration can increase cortisol levels;
  • use music, massage and meditation: each is therapeutic and provides relaxation responses that can alleviate pain, improve the immune system and manage chronic illness symptoms;
  • know and love yourself: recognize your limits, respect your health priorities, and find ways to restore mood and energy (take breaks, slow down and go on vacation);
  • love life: pursue joy, passion, life long learning and a deeper purpose than the individual self.

There are many factors that can shift or impact mood, including stress, fatigue and relationship factors. Feeling down or depressed are common phenomena. Use these simple steps to uplift and improve mood, reduce stress and boost energy for the rest of the day. Investing the time to include them in your regular routines will support your overall physical and emotional wellbeing.

 

Sleep and Exercise. Getting enough sleep on a consistent basis is a critical factor for overall wellbeing. Although individual needs may differ, it is commonly agreed that adequate sleep and maintaining a sleep hygiene are a basic need to feeling good. Exercise is known to immediately reduce stress, increase energy and improve mood. Consider going for a walk or engaging in physical activity of choice on a regular basis. Healthy routines are easier to perform once they become habits.

Practice Gratitude and Appreciation. Maintaining a regular practice of gratitude brings happier feelings and heartfelt appreciation for the positive aspects in life. You can write a gratitude journal, feel appreciation in silent moments of prayer or be thankful at meals with family, friends or alone. Feeling appreciation, gratitude and contentment have shown to improve physical health, psychological wellbeing and a sense of peace.

Get a Massage. The benefits of massage are countless, from relaxation to pain management. Massages can effectively combat stress, relieve pain and tension, improve sleep, increase circulation, eliminate toxins, address headaches and diminish anxiety. Regular massage can reduce heart rate, cortisol and insulin levels and help maintain muscles more relaxed even during post-massage moments.

Help Someone. Service to others involve empathy and compassion. People report feeling happy when donating to charity or volunteering. Helping others does not necessarily require time, energy or money. Any form of altruism, such as a genuine smile or random acts of kindness create a sense of fulfillment and wellbeing. Helping others is an effective mood lifter. Find what suits you to start rejoicing in life.

Mood Enhancing Food. While chocolate can bring an immediate rush of energy and euphoria, avoid foods that will cause drops in sugar levels, leaving you down and drained, such as cookies, candies and soda. Eating smaller portions at regular intervals, increasing foods rich in omega-3 (salmon, sardines, walnuts, flax-seeds), and including small amount of protein at every meal can help lift your mood. Turkey, beef, eggs and dark leafy greens provide tryptophan, a precursor to serotonin which is, among other things, a natural mood stabilizer.

Enjoy the Senses. Spending time in nature can have healing results and invoke a state of relaxation, whether it is a walk on the beach or a picnic in the park. Take a break to disconnect from daily stressors. Indulge your senses in aromatherapy, light a candle, soak in a scented bubble bath, or listen to your favourite music. Whether you walk away from your desk or take a vacation, mood management can offer many options that suit your situation.

Create your Own Mood Lifting List. Prepare your own mood enhancing tool kit and implement simple daily stress busters to feel good. The list may include the quickest strategy such as smelling a favourite fragrance or opening a drawer of happy items (photos, gifts, awards received, a dream trip, or an inspiring quote). For others, feeling good can be found in quiet prayer, yoga stretching or guided meditation. Consistent and deliberate action can make your day more proactive, productive and pleasant for yourself and others and avoid the helplessness of depression.
