Optimal Circulation & Health of Sitting
Veli-Jussi Jalkanen
Mr. Veli-Jussi Jalkanen is a health inventor, CAM and sitting health specialist. He has logically spread out sitting optimization to comprehend the whole physical working environment and started to think ergonomics as optimization of micro and macro circulation of the lymph and blood. Salli Concept includes awareness, furniture, their optimal use, sitting friendly clothing and body activity in numerous ways including PDNF, hormones and the electromagnetic body.
Veli-Jussi Jalkanen's talk explores optimal
Even small micro-movements, which we do unconsciously, will activate muscles and circulation. We don't even need to think about it; we just learn it.
Summary
- Lowering the thighs and straightening the hips improves posture and circulation compared to traditional sitting angles. - Unconscious micro-movements while sitting activate spinal muscles and promote the health of internal organs by encouraging continuous blood flow. - A divided seat design eliminates unhealthy pressure on the pelvic floor, preventing the compression of critical pudendal arteries, veins, and nerves. - Standard underwear and padded chairs can raise testicular temperature to 37°C, which negatively impacts testosterone levels and semen quality. - Maintaining pelvic circulation is vital for the immune system, allowing white blood cells to reach internal organs and combat bacterial inflammation.

Optimal Circulation And The Health Of Sitting
At Biohacker Summit 2018 Stockholm, Veli-Jussi Jalkanen Turned An Ordinary Chair Into An Indictment Of Modern Life
There are few habits so universal, so unexamined, and so quietly punishing as sitting. At Biohacker Summit 2018 Stockholm, held on 18 May 2018 in Stockholm, Sweden, Veli-Jussi Jalkanen approached that everyday act not as a matter of comfort, but as a matter of circulation, fertility, immunity and human design.
Jalkanen, a Finnish health inventor and specialist in sitting health, delivered his presentation, *Optimal Circulation & Health of Sitting*, with the air of a man arguing that one of the most familiar features of modern life had been disastrously misunderstood. His thesis was stark: the conventional chair did not merely support the body poorly. It compressed it, heated it, stagnated it and, in ways both intimate and systemic, undermined health.
The Body Was Not Built For Static Compression
Jalkanen reduced his argument to three essential principles. The first was posture. “Get the thighs down and the hips more straightened out to experience the true benefits of optimal sitting,” he said, contrasting the closed, bent geometry of standard seating with a more open hip angle that, in his view, better preserved circulation.
The second was movement, especially the kind that hardly announces itself. “Mobility is important because it activates the muscles around the spine and promotes the health of your internal organs,” Jalkanen told the audience. Even micro-movements, he argued, mattered. Tiny unconscious shifts while seated could keep spinal musculature engaged and help sustain the internal flow of blood and lymph through the abdominal region.
His point was not that people should fidget more out of discipline, but that seating should permit and encourage those subtle adjustments. A good chair, in this vision, did not immobilise the body. It collaborated with it.
Pressure, Not Just Posture, Was The Hidden Villain
If Jalkanen’s first two points addressed alignment and mobility, the third went to the anatomical heart of his case: pressure beneath the pelvic floor.
“We need to remove the unhealthy pressure underneath the pelvic floor to increase circulation throughout the body,” he said. To illustrate the idea, the presentation moved from theory into demonstration. Using a belt and a conventional, non-divided chair, he sought to show the degree of friction and force created when the body’s weight bore down on a continuous seat surface.
The demonstration was theatrical, even provocative, but the argument beneath it was consistent. According to Jalkanen, ordinary chairs concentrated enough pressure under the pelvis to impede circulation not only at the surface, but deeper within the pelvic cavity. In his framing, the issue was not local discomfort. It was a structural blockage with systemic consequences.
The Pelvic Floor Became The Center Of A Larger Health Argument
Jalkanen pointed to the pudendal vessels and nerves, which serve the genital region, as especially vulnerable to compression from sitting. These structures, he said, could be pressed between the body and the chair, with repercussions extending to sexual and reproductive health.
“The results we see are poor semen quality, poor testosterone levels, poor erectile functions,” he told the room, in one of the bluntest moments of the session.
Whether discussing men or women, Jalkanen’s larger claim was that circulation through the pelvis should be treated as foundational, not peripheral. The pelvis, in his account, was not simply a load-bearing zone at the bottom of the torso. It was a crowded and delicate crossroads of vessels, nerves and organs, and conventional seating placed that entire region under unnecessary strain.
Heat, Clothing And Fertility Entered The Conversation
The talk then widened from chairs to clothing, particularly underwear and padded seating. Jalkanen argued that modern garments often trapped heat and constricted the body in ways people had accepted as normal only through habit.
“When we allow the body liberty from stuffy and squeezing clothing, we support the natural temperature and circulation it needs to thrive,” he said.
He was especially emphatic on the issue of testicular temperature. Men’s testicles, he argued, function best at a cooler temperature than the body’s core, and sitting in underwear on padded chairs could raise that temperature to harmful levels. In his telling, heat and pressure formed a particularly damaging alliance: one compromised physiological cooling, the other restricted circulation.
It was a characteristically uncompromising moment in a talk that repeatedly insisted that convenience and convention had overridden biological common sense.
Circulation Was Cast As An Immune Issue, Too
Perhaps the most striking dimension of Jalkanen’s presentation was the way it linked sitting to immunity. He argued that blocked circulation in the pelvic region could interfere with the body’s ability to dispatch immune cells to areas of emerging inflammation or infection.
“Our immune system wants to shut down inflammation, but it cannot do its work if the circulation is blocked,” he said.
That claim carried the discussion beyond ergonomics and into the language of vulnerability. Inflammation, bacterial spread and impaired defence were all presented as downstream effects of pressure and stagnation. In Jalkanen’s account, poor sitting was not merely bad mechanics. It created the conditions in which the body’s protective systems were less able to respond.
Hygiene, Friction And The Risks Of Sedentary Design
Jalkanen also connected sitting to hygiene in a notably direct way. Friction, sweat and proximity, he suggested, could aid bacterial migration from the anal area toward the urinary or genital tracts, especially when circulation was already compromised. He urged better washing habits after toileting as part of a broader preventive approach.
The message was not polished into the soft language of wellness culture. It was physical, practical and, at times, unsettling. But that was precisely the force of the session. Jalkanen was determined to collapse the distance between what people considered mundane and what the body experienced as consequential.
A Radical Reading Of An Everyday Habit
By the end of *Optimal Circulation & Health of Sitting*, Jalkanen had offered more than ergonomic advice. He had presented a philosophy of the seated body, one rooted in openness, mobility, cooling and unobstructed flow. Lower the thighs. Straighten the hips. Allow micro-movements. Avoid compressive surfaces. Choose breathable clothing. Protect circulation as if other systems depend on it, because, he argued, they do.
At Biohacker Summit 2018 Stockholm, Veli-Jussi Jalkanen made a familiar object seem newly suspect. The chair, that emblem of modern work and sedentary normality, emerged from his talk not as neutral furniture but as a daily instrument of compromise. And in that reframing lay the provocation at the centre of his message: that health may depend not only on how much we move, but on how intelligently we sit.
