IMMUNITY BOOST

RAKxa, Bangkok, Thailand

3Despite it being a river hop from Bangkok, there is a sense of the clandestine about this hush-hush island retreat that officially opened in 2021 but, owing to the pandemic, is only really now starting to see clients through the door. Thailand is tricky to enter at the moment, but for winter sun next season this is worth holding out for if you want a full-body MOT rather than a mere massage; high-tech treatments mixed with ancient Ayurveda produce astounding results. A long-Covid programme has even been introduced, aimed at targeting the respiratory system and reducing inflammation.

After an initial consultation with a doctor, a tailor-made programme is created including everything from fitness training to IV ozone therapy and immune infusion with laser therapy, alongside traditional massages, corrective exercises, acupuncture, chakra balancing, and access to a hyperbaric chamber, where your lungs gather more oxygen than normal to help fight bacteria. Even without a personalised programme guests are guaranteed to leave here feeling healthier than when they arrived, thanks to the food (nutritionists work in sync with doctors and chefs to ensure you are staying clean and lean), cleansing tea lounge, gym, hydrothermal spa and relaxing villas spread around a lake and surrounded by lush jungle.

Three-night long-Covid programme from £3,172 (00 66 2055 3100; rakxawellness.com)
