Why Eating Outside Is Good for Your Health This Summer

When the sun makes an appearance, most of us naturally want to spend more time outdoors. Whether it's a picnic in the park, lunch in the garden or simply taking your sandwich outside during your work break, eating al fresco is one of the simplest ways to make the most of summer.

What you might not realise is that there are genuine health benefits to taking your meals outside. From boosting your vitamin D levels to supporting better digestion and encouraging you to eat more seasonal foods, a little fresh air can do far more than simply brighten your lunchtime.

Top up your vitamin D naturally

One of the biggest advantages of spending time outdoors during the summer is the opportunity to increase your vitamin D levels naturally.

Most of us think of vitamin D as being important for healthy bones, but its role in the body goes much further. Vitamin D supports normal muscle function, contributes to energy production and plays an important role in maintaining a healthy immune system. Low vitamin D levels have also been associated with low mood and high blood pressure.

The good news is that, during the summer months (generally between May and the end of September), most people in the UK can make enough vitamin D from sunlight on their skin.

Aim to spend around 10–15 minutes outdoors between 11am and 3pm with some skin exposed, without sunscreen for that short period, taking care not to burn. If you have naturally darker skin or it's a cloudy day, you may need a little longer.

One app I often recommend is D-Minder, which helps you estimate your personal vitamin D production based on factors such as your location, skin type and the weather. It can also be helpful to have your vitamin D levels tested once at the end of summer and again at the end of winter, so you know whether your levels are where they should be.

Eating outside encourages mindful eating

Taking your lunch outdoors isn't just good for your vitamin D levels. It can also help you slow down and enjoy your food more.

Research continues to show that spending time in nature helps calm our nervous system. When we step away from our desks, screens and busy environments, our bodies are more likely to switch into what's known as the parasympathetic nervous system — often referred to as the "rest and digest" state.

This is exactly where we want to be when we're eating.

When we're relaxed, digestion tends to work more efficiently. We chew our food more thoroughly, notice when we're full and often enjoy our meals much more. Even taking five or ten minutes to sit quietly outside while you eat can make a real difference.

Next time you're having lunch outdoors, take a moment to notice what's around you. Listen to the birds, feel the warmth of the sunshine or notice the breeze. These small moments of mindfulness can help reduce stress while supporting better digestion.

Fresh from the garden to your plate

If you're lucky enough to have a garden, vegetable patch or even a few pots on your windowsill, summer is the perfect time to enjoy homegrown produce.

There's something incredibly satisfying about picking your own herbs, salad leaves or tomatoes and adding them straight to your lunch. Not only do they taste fantastic, but they also provide the maximum nutritional value because they've been picked at their freshest.

There are no food miles, no unnecessary packaging and no long periods of storage. Just fresh, seasonal food straight from the planter to your plate.

Even if you haven't started growing anything yet, it's not too late. A packet of mixed salad leaves can provide a harvest within four to six weeks, making it one of the easiest ways to start growing your own food.

And don't forget edible flowers. Nasturtiums, calendula and borage all make beautiful additions to salads while providing extra nutrients and colour.

Make the most of seasonal produce

Even if you don't grow your own food, there is plenty of wonderful local produce available throughout the summer.

Seasonal vegetables such as peas, broad beans, spinach, kale, chard, radishes, cucumber, tomatoes, beetroot and new potatoes are packed with flavour and nutrition at this time of year.

Summer also brings an abundance of delicious berries. Strawberries are at their sweetest, early raspberries are ready for picking, and you'll soon find blueberries, gooseberries and tayberries appearing too.

Eating seasonally means you're enjoying foods when they're naturally ripe. As fruit and vegetables ripen, they develop their fullest flavour while also concentrating many of their vitamins, minerals and protective antioxidants.

The result? Better taste, better nutrition and often better value too.

A simple healthy habit to embrace this summer

Healthy living doesn't always have to involve major lifestyle changes. Sometimes the simplest habits are the ones that make the biggest difference.

Taking your lunch outside allows you to soak up some sunshine, support your vitamin D levels, calm your nervous system, improve digestion and reconnect with seasonal food—all in one meal.

So, whether you're eating in your own garden, enjoying your local park or simply sitting on a bench outside your workplace, make the most of the beautiful weather while it's here.

Your body - and your mind - will thank you for it.
