Summer holidays bring adventure, movement and sunshine — but also heat, dehydration, disrupted routines and digestive changes. Whether you're travelling abroad or exploring locally, a few science-informed habits may help you look after yourself throughout the season.

Here are some simple, research-informed suggestions for this summer.

Tip 1: Stay Hydrated with Electrolytes

Water alone isn't always enough on hot days. When you sweat, your body loses not only water but also essential electrolytes such as sodium, potassium and magnesium — minerals needed to:

  • prevent dehydration
  • regulate blood pressure
  • support muscle contractions
  • maintain nerve function

Electrolyte drinks or tablets can help replenish these minerals, especially during long sightseeing days or beach activities. Carrying a reusable water bottle keeps hydration effortless wherever you go.

Tip 2: Choose the Right Sun Protection

Daily UV exposure is one of the biggest contributors to premature aging. While both mineral and chemical sunscreens protect the skin, mineral-based sunscreens containing zinc oxide or titanium dioxide sit on the skin's surface and reflect UV rays, making them a preferred choice for:

  • people with sensitive skin
  • reducing chemical absorption concerns
  • broad-spectrum protection

They are also more photostable under intense sunlight — ideal for long beach days or high-UV environments.

Other daily habits include:

  • reapplying every two hours
  • using hats and UPF clothing
  • avoiding peak UV hours (11am–3pm)

Tip 3: Pack Probiotics — Your Travel Essential

Travel often disrupts gut balance due to new foods, irregular meals and stress. This can affect:

  • digestive comfort
  • inflammation levels
  • immune function
  • mood and cognitive clarity (via the gut-brain axis)

Probiotics may support a balanced gut flora. Research has linked a healthy microbiome with immune function and even mood regulation — which may be relevant when adjusting to time zones or new environments.

To support gut function:

  • take a daily probiotic
  • include fibre-rich foods
  • stay hydrated
  • choose fermented foods where available

Small Habits Make a Big Difference

Summer should feel energising, not exhausting. By staying hydrated with electrolytes, choosing effective sun protection and supporting gut health with probiotics, you can enjoy your travels while looking after your wellbeing.
