During the summer months, it's normal to experience some increased bloating and swelling. But that often leaves us feeling uncomfortable and self-conscious. While there are a variety of factors that contribute to this change, a few are unique to the warmer weather, which is why it’s not unusual to be greeted with the swelling and bloating quite suddenly, even if you don’t experience these symptoms throughout the rest of the year.
Heat and humidity can lead to increased water retention, while changes in diet, such as consuming more salty and processed foods while trying to cool down at the pub, can exacerbate the issue. Curious what's happening in your body? There's actually a pretty simple reason.
Vasodilation of blood vessels traps excess water in our cells, which is where that feeling of ‘I’m full of water’ tends to come from. Similarly, excess lymph fluid can impact swelling and congestion around the body, where we often see lymphatic swelling and discomfort. Additionally, the body’s response to higher temperatures includes dilating blood vessels to help cool the body down, which can contribute to swelling. Understanding these underlying causes can help in taking proactive steps to minimise discomfort and enjoy the summer season to its fullest.
Of course, if you're traveling, the change in time zones, routine, and diet can also have an impact on how regular our bowel movements are (read more on that here).
All this being said, there are a few cases in which swelling and water retention can be a sign of cardiovascular or thyroid conditions, and chronic bloating can also be a symptom of further gut dysbiosis, so it’s important to keep an eye on your symptoms and address your concerns with a healthcare practitioner.
This has been shown to reduce gravitational pressure on the veins in your lower body whilst also stimulating blood flow towards the heart, igniting better blood flow.
Appropriate hydration prevents water retention by maintaining fluid and electrolyte balance enabling the kidneys to excrete excess water and sodium efficiently. When the body is dehydrated, it conserves water, leading to bloating and swelling.
Drinking enough water dilutes sodium concentration in the bloodstream, supports digestion, and promotes effective lymphatic function, all of which reduce fluid buildup and discomfort. Thus, staying well-hydrated is key to minimising water retention, especially during the summer months.

Saunas induce sweating and help reduce temporary fluid retention whilst enhancing blood circulation to move waste and fluids from tissues. It may seem couter-productive to get hotter when you’re already hot, but purposeful sweat sessions are a Healf hack and the dedicated time allows for sweat to escape.
When using a sauna, you can enhance the benefits using binders to ensure that any waste material binds and is therefore eliminated from the body.
Whether you book in for a specific massage or ensure your dry body brush daily increases tissue oxygenation and toxin elimination.
The simplicity of a basic massage helps move extra fluid from an area that is swollen (or is at risk of becoming swollen), into an area where the lymph nodes are working properly.

The summer months are the months that we want to be socialising and enjoying time with our loved ones. Rather than removing and eliminating food groups, prioritise what you can add to your plate instead. Whether it’s a handful of bitter greens to stimulate digestion, an additional protein source with your breakfast to stabilise your blood sugar or opting for brown bread over white for an abundance of fibre.
Certain foods can also aid hydration. They tend to be the ‘juicier’ foods that we crave on our summer holidays, with high water content, such as cucumbers, watermelon, strawberries, spinach, and lettuce. Our bodies have a great way of telling us what they need.
Potassium-rich foods like bananas and avocados regulate sodium and prevent excess retention too which is why it is recommended to have these foods following a heavy workout or sweat session. Natural diuretics like celery, dandelion and asparagus reduce bloating whilst also stimulating water release via the bladder.
These foods, along with adequate water intake, support optimal hydration and overall health.
Put away your laptop, turn off the television and be present with your food. Digestion starts with your senses by telling your body that there is food incoming, it stimulates your digestive juices and enzymes to break down the food that you are eating. Similarly, it also tells your brain there’s food incoming and will register that you are eating and activating your satiety queues without overeating.
Throughout the day, placing effort and emphasis on your breathing and directing the breath to your abdomen allows the digestive system fresh, oxygenated blood flow whilst also allowing space for appropriate digestion to happen.
“Something I see frequently is when people suffer with digestive discomfort but spend a lot of their day hunched over or crumpled up, this puts a lot of pressure on our digestive organs and restricts them. Opening up the front of the body with chest extension exercises and stretches with deep inhalations and longer exhalations combats this also.”
Similarly to above, including bitter foods such as rocket, dandelion, watercress and cacao nibs make a great starter for igniting digestive fire. Eating these foods before a meal stimulate the liver and produce bile from the gallbladder to release digestive juices.
Not only this but green bitter vegetables work to line the gut wall acting as a ‘buffer’ for higher carb foods which can also impact blood sugar.
Herbs such as peppermint, chamomile, ginger and lavender are calming and soothing for an inflamed digestive tract which can alleviate the sensation of bloating and trapped wind. Similarly, using herbs such as dandelion, cleavers, nettle and burdock can also help stimulate the lymphatic and detoxification pathways in the body.
Ultimately, understanding the ‘why’ behind symptoms such as bloating and water retention can stop symptoms progressing in their tracks.
