A small share of travellers accounts for a disproportionate share of spending, and they choose their hotel on criteria that most hotels do not publish.

Why it matters

We call them the longevity segment: guests who measure their sleep, track their recovery and compare venues before booking. They are not numerous. They are mobile, informed, and they spend.

What the market publishes

The wellness economy. The Global Wellness Institute estimates it at 6,800 billion dollars in 2024, or 6.12 % of global output, and projects around 9,800 billion in 2029. GWI, 2025.

Wellness tourism. For 2022, the GWI counts 819 million wellness trips. They account for 7.8 % of trips, but 18.7 % of tourism spending. An international wellness traveller spends on average 1,764 $ per trip, 41 % more than the average international traveller; a domestic one, 668 $, 175 % more. GWI, 2023.

What this does to the hotel. In the first half of 2025, across more than 11,000 hotels, RLA Global and HotStats measure total revenue per occupied room of 561 $ in hotels with a strong wellness component, against 335 $ in the others. RLA Global, 2025.

What is self-reported or partial

The size of the segment. No study counts it directly. Online communities give an order of magnitude: around 913,000 members on the r/Biohackers forum, up 39 % in a year, and around 213,000 on r/longevity, according to a third-party tracking tool updated at the end of September 2026. A member is not a guest, and many belong to both forums.

What they say they want. An Amerisleep survey of 1,000 Americans in June 2026 indicates that 43 % would pay more for a sleep-friendly room, with an average supplement mentioned of 158 $. The priorities cited are soundproofing, blackout and a cooling mattress. This is self-reported: an intention, not spending.

What they criticise. On forums and in the specialist press, the same criticisms recur: a spa renamed "longevity" with no real change, prices with no published results, no follow-up after the stay. These criticisms are not quantified; they are constant.

What cannot be claimed

We do not say how many guests from the longevity segment a hotel will attract. No one measures it today, and we do not make it up.

We do not say that the GWI's wellness travellers and the longevity segment are the same population. The latter is a more demanding subset of the former.

We do not say that this segment will pay any price. It is precisely the one that checks.

What a hotel can do

First, meet the basic demand. The most frequently cited expectations are simple: darkness, silence, temperature, bedding, air, a proper strength room. A hotel that gets these right and measures them already stands out from most of its competitors.

Publish what is measured. These guests compare. They choose the venue that gives its figures, not the one that makes promises. The cost is low; the gain is an argument the others do not have.

Serve ordinary guests too. The devices offered at 50 € a night and the longevity menu at 60 to 150 € per session are aimed at all the hotel's guests. The longevity segment draws attention; ordinary guests carry the volume.

Two lines of gain. Margin, carried by all guests. Capture, carried by the segment: nights taken from the competition, at a higher rate. In our model, the investment is recovered within a few months. The Mission (20,000 € excl. VAT) quantifies it on the hotel's actual data; the Audit (3,000 € excl. VAT) first shows where the hotel stands.

What the Living Lab measures

The Living Lab, near Lisbon, does not measure the size of a market. It observes what these guests actually use when they have the choice.

Measurement planned. For each device and each service: frequency of actual use, duration, questions asked, time to get started, incidents. Each reading will be dated and published here.
