You push through weeks of deadlines, finally book the leave, and the moment you're supposed to be relaxing on day one — sore throat, headache, or a full-blown cold shows up instead. If this feels like a pattern rather than bad luck, there's actually a name for it: leisure sickness. It's a real, documented phenomenon, and understanding why it happens is the first step to doing something about it — including where GreenKare Lingzhi ImmuPlus can genuinely help.
Stress hormones were propping you up the whole time
While you're grinding through a busy stretch, your body runs on stress hormones like cortisol and adrenaline. In the short term, these can actually keep your immune system on high alert and mask fatigue — which is part of why you can push through a brutal work week feeling "fine," only to fall apart the moment it ends.
The "let-down effect" hits right as you relax
Once the pressure lifts, those stress hormones drop fairly quickly — and your immune system, which had been running in overdrive, effectively has to recalibrate. That readjustment window is when a lot of people find themselves suddenly vulnerable to whatever bug they'd been fighting off without realising it.
Sleep debt from the lead-up makes it worse
The nights before a big trip or a long-awaited break are rarely restful — last-minute packing, wrapping up work, staying up later than usual. That accumulated sleep debt compounds the immune dip from dropping cortisol, which is why the first day or two of a holiday is often the worst.

Ever booked time off and immediately come down with something the moment you finally stopped? Tell us about it in the comments — we're curious how common "leisure sickness" really is among Singapore's always-on workforce.
Where nutritional support fits in
You can't eliminate work stress entirely, but you can support your immune system so it isn't running purely on adrenaline in the meantime. GreenKare Lingzhi ImmuPlus combines cracked-spore Lingzhi (Ganoderma) — a traditional ingredient long associated with immune support and vitality — with grape seed extract for antioxidant support and acerola cherry for natural vitamin C. Taken consistently, especially through a demanding work stretch, it's designed to help your immune system stay steadier, rather than leaving it to crash the moment you finally get to rest.
