Transcendental meditation is a mantra-based meditation technique. You will reach inner peace by mentally repeating a word or phrase. Notably, this type of meditation gives many opportunities for solving both physical and psychological issues.
Maharishi Mahesh Yogi introduced Transcendental Meditation (TM) in its current form in the 1970s. The mantra repeated during a meditation session distinguishes transcendental meditation from other kinds of meditation. The mantra in TM is a meaningless sound that is utilized as a vehicle to assist the mind settle down. During the meditation practice, other types of meditation employ words, phrases, or visions. You want to achieve absolute stillness and consciousness by focusing solely on your mantra.
This is where TM’s evidence is strongest, and it’s genuinely worth updating on: the 2025 AHA/ACC high blood pressure guidelines now state that stress reduction through TM “may be reasonable to prevent or treat elevated BP and hypertension, as an adjunct to lifestyle or medication interventions.” This builds on a 2013 AHA scientific statement and multiple randomised controlled trials showing TM associated with modest blood pressure reductions (commonly in the range of 4–5 mmHg systolic).
It’s worth being precise about what this means: TM is recognised as a reasonable complementary approach – used alongside medication and lifestyle changes, not instead of them – and the AHA itself has noted some uncertainty about whether TM’s effect is meaningfully different from other stress-reduction or relaxation techniques. Chronic stress is a genuine risk factor for cardiovascular disease, contributing to elevated blood pressure and other risk factors over time, and TM’s stress-reduction effect is the likely mechanism behind its blood-pressure benefit – but it isn’t a standalone treatment for heart disease, and shouldn’t replace prescribed cardiovascular medication without your doctor’s guidance.
While medicine can help with short-term symptoms, TM can treat the root problem, which deprives the body of the opportunity to recuperate and return to balance. When taking TM, the mind may be subjected to a few seconds of deep quiet. However, this is sufficient to provide the body with profound relaxation, considerably deeper than sleep. Its primary stress-relieving benefits include regulating nerve system activity, and hormone levels, and promoting brain coherence. From this, deep-seated strains and tensions spontaneously dissolve, which leads to clear our senses, reverse the cycle of stress buildup, and deliver relief to a wide spectrum of individual and social human issues.
Insomnia is a sleep disorder that regularly affects millions of people worldwide. Inadequate or poor-quality sleep has been proven to impair brain regions important for concentration, mental agility, and memory consolidation, as well as increase the possibility of getting inflammation, immunological response, diabetes, and cancer risk.
The amount of rest experienced with everyday TM practice is profound and considerable. The body deals with both the pressures of the day and the longer-term, more deeply entrenched ones, releasing weariness and other undesirable consequences. As a result, the body has less work to accomplish at night, enabling sleep to return to normal.
Sleep improvement adds greatly to the advantages seen in other areas of life. In longer-term meditators with regular TM practice, after dealing with the backlog of sleep deprivation, the quality of sleep greatly is improved and the backlog of sleep deprivation is dealt with.
Research on meditation practices generally has found associations with changes in brain function relevant to attention and emotional regulation. Evidence specific to TM’s cognitive effects is more limited than its blood pressure research, so this should be considered a plausible, but less firmly established, benefit.
A small 2020 study of South African university students with clinically diagnosed PTSD found that those practising TM twice daily showed significant improvement in PTSD symptoms and depression compared to a comparison group, with results linked to how consistently they practised. This is a genuinely interesting finding, but it’s a single, relatively small study (34 people per group) rather than a large, replicated trial – worth knowing about, not treating as definitive. If you have PTSD, it’s important to work with a mental health professional on evidence-based treatment, with TM considered, if at all, as a potential complementary practice rather than a primary treatment.
Transcendental meditation is an easy-to-learn practice. You don’t necessarily have an assistant for your transcendental meditation. However, in order to master the method properly, you should study with a trained transcendental meditation teacher.
Practicing 20 minutes twice per day, before breakfast or dinner is ideal for you to find a comfortable place and take transcendental meditation.
Take the following steps:
The strongest evidence is for modest blood pressure reduction, now recognised in 2025 AHA/ACC guidelines as a reasonable adjunct therapy. Other associated benefits include stress reduction and improved sleep quality, with more limited evidence for cognitive and PTSD-related benefits.
No – even the AHA guideline recognising TM’s blood pressure benefit frames it as an adjunct to medication and lifestyle changes, not a replacement. Speak with your doctor before making any changes to prescribed treatment.
Yes, to a meaningful degree, particularly for blood pressure – though it’s worth knowing that a substantial portion of TM-specific research has been conducted by TM-affiliated researchers, which is part of why some evidence reviews describe the certainty of its unique benefit (versus other relaxation techniques) as still somewhat uncertain.
Typically, yes – TM is usually taught through a structured course with a certified instructor, unlike some other meditation styles that can be more easily self-taught.
Some preliminary research suggests it may help reduce PTSD symptoms, but evidence is limited to small studies. It should be considered a potential complementary practice alongside professional mental health treatment, not a replacement for it.
Transcendental Meditation has a more substantial evidence base than many complementary practices, particularly for blood pressure – recognised as recently as 2025 in major US cardiology guidelines as a reasonable adjunct therapy. Its benefits for stress, sleep, and mental clarity are plausible and supported by some research, though generally less robustly established than its cardiovascular effect. If you’re considering TM, it’s worth approaching it as a complement to medical care rather than a replacement for it – particularly if you have high blood pressure, PTSD, or another condition already being treated, consult a doctor through the MaNaDr App for personal guidance on your current treatment.
