On hot summer days, your body deserves some extra care. The heat causes your blood vessels to expand, which makes you start sweating and increases your heart rate. This means your body will do everything it can to cool down – and here’s where you can give it a little help!
Our thermal baths are the ideal place to cool down responsibly. A spa is also about balance in summer, between hot and cold, action and rest, sun and shade. And you can find all that at Thermae Grimbergen!
The easiest way to cool down? A cold shower. Sounds basic, but the effect is powerful. The cold water instantly lowers your body temperature, closes your pores, and helps you stop sweating.
On the grounds of Thermae Grimbergen, you’ll find several cold showers. Ideal after a sauna session, but also perfect for freshening up in between. Do you find it hard to stand under the cold stream? Try this simple breathing exercise: inhale for 3 counts, hold for 3 counts, and exhale for 3 counts. Repeat this a few times – you’ll find you tolerate the cold better and it calms your mind too.
On the terrace in the swimwear area, you’ll find a cold plunge pool – and our swimming pond in the nude area is also perfect for dipping in and cooling off. Especially after a hot sauna session, it does wonders: you can literally feel your heart rate slow down and your body refresh in no time.
Two smart tips to get the most out of your plunge pool:
A sauna on a scorching hot day? To some, it sounds strange, but once you’ve tried it you’ll almost certainly be convinced. In summer, a sauna visit is even particularly beneficial: it helps your body adapt better to temperature changes and supports your immunity.
In summer temperatures, you may opt for a sauna with milder heat or an infrared cabin. And, above all, remember to cool down properly after each session and allow yourself plenty of breaks in between. The result? A fresh feeling and a balanced body.
Thermae Grimbergen is surrounded by greenery and tranquillity. In our garden, you’ll find plenty of spots to shelter under the trees or relax with a gentle breeze. Settle down on a lounger in the shade, stroll around the beautiful estate, or take a dip in one of the outdoor pools or the swimming pond.
The combination of sun, water, and nature works wonders for your spirits. And feeling thirsty? Our wellness bar serves refreshing drinks. Why not try a homemade lemonade or iced tea? Delicious and hydrating! Tip: go easy on the alcohol on hot days, as it can dehydrate your body even more.
During the summer months, refreshing facials and relaxing treatments feel even more blissful. For example, choose a facial with a hydrating gel mask or an exfoliating scrub that purifies your skin, helping you achieve a beautiful tan.
Our massages can also be tailored to the season – with light oils, fresh scents, and gentle techniques that soothe your skin as well as your muscles. So why not combine your wellness day with a treatment? Your skin will glow and you’ll go home with renewed energy.
This summer, Thermae Grimbergen is your place to truly unwind. Away from the crowds and heat, and completely tailored to what your body and mind need: cooling, relaxation, and rest.
Schedule your summer pampering moment today and discover how wonderful it is to cool off in style.
