The one-week rule

Remember when scoring an international business trip felt like winning the office lottery? Reality check: your body disagrees and will thank you for this business travel hack …

That five-day sprint to Tokyo – the one with back-to-back meetings and seven-hour time difference – is why you’re spending every weekend in recovery mode. Come Monday, you’re back at your desk, running on fumes.

Here’s what business travel experts now understand: it’s not you, it’s your itinerary.

“Most travellers blame themselves when they feel wrecked after business trips,” says Mummy Mafojane, GM at FCM, the flagship corporate travel brand at Flight Centre Travel Group. “They think they should sleep better, hydrate more, or hit the hotel gym. But they’re missing the fundamental issue – their bodies literally need more time to adjust.”

Enter the one-week rule, possibly the most straightforward travel wellness hack you’ll ever implement. The concept is based on solid physiological research: your body requires approximately one day per time zone crossed to recalibrate its circadian rhythm. Crossing six time zones, it takes six days; for seven zones, it takes seven days. It’s that simple.

Yet, most business trips still follow the outdated three- to five-day model, which guarantees you’re heading home precisely when your body has barely started adjusting to local time. This leads to major negative fallout.

A study from Columbia University’s Mailman School of Public Health found that employees who travel extensively report higher stress levels and significantly worse health outcomes than their non-travelling colleagues. Meanwhile, research from World Travel Protection (which specialises in global travel risk management services) revealed that over half of frequent business travellers experience burnout symptoms directly tied to their travel patterns.

When your circadian rhythm is disrupted, your cognitive function takes a serious hit. Decision-making suffers. Creativity plummets. Immune function weakens. Your ability to read social cues – which is crucial in cross-cultural business settings – also deteriorates. Add the pressure of high-stakes meetings in unfamiliar settings, and you’ve got the perfect storm for subpar performance.

“We’ve normalised the idea of pushing through jet lag,” says Mafojane. “But would you expect an athlete to compete at their peak while sleep-deprived and disoriented? Then why do we expect it from business professionals making million-rand decisions?”

The one-week recommendation

Mafojane says travel management companies like FCM are increasingly recommending a wellness-forward approach. “Companies need to have candid conversations about the hidden costs of compressed trips,” she says.

“When executives understand they’re potentially operating at 60 to 70% capacity during these quick trips – and the business implications of that – the one-week rule suddenly makes perfect sense.”

Adapting your travel policy

For organisations serious about implementing the one-week rule, Mafojane recommends a phased approach: “Start with your highest-value international trips – those crossing five or more time zones with significant business impact.” She suggests companies first target traveller segments most affected by jet lag: executives over 50, team members with health considerations, and those making presentations or negotiations within 24 hours of arrival. 

“Document the business case beyond wellness,” she emphasises. “Better preparation, stronger relationship-building, higher-quality decision-making – these are measurable advantages of properly timed trips.”

Even for organisations unable to immediately implement the full one-week policy, Mafojane recommends incremental improvements: “Add just one adaptation day to existing trips. Allow work-from-hotel mornings after overnight flights. Create space in the schedule for recovery. Even small changes yield significant benefits.”

Beyond extending your stay, Mafojane adds that the following strategies can also dramatically improve your travel experience:

Landing during daylight hours gives your body crucial light exposure that helps to reset your internal clock faster. Mafojane recommends prioritising these arrival times over rock-bottom fares when possible.

She also recommends sleep-proofing your hotel. “Look beyond the standard hotel amenities,” she emphasises. “Quality blackout curtains, rooms away from lifts, premium bedding – these aren’t luxuries, they’re recovery tools.” She suggests requesting these specifications when booking accommodations.

Build in buffer zones by scheduling at least one full day before critical presentations or negotiations when crossing multiple time zones. Similarly, avoid packing your calendar the day you return home.

Mafojane stresses the importance of logging off meaningfully by setting travel communication protocols that protect adjustment periods. “Travellers should establish clear availability windows while abroad,” she elaborates. “Constant connectivity to the home office disrupts your ability to adapt to local time.”

The bottom line? Your next business trip shouldn’t feel like a hostage negotiation with your own biology. So, if someone questions your extended international itinerary, remind them: you’re not on vacation, you’re giving your brain the courtesy of showing up to the meeting. Quite frankly, your spreadsheets will thank you for it. After all, if you’re going to fly halfway around the world to make an impression, shouldn’t you arrive with all your talents intact?
