A scan reflects the state you arrive in. Five minutes of preparation makes results dramatically more useful.
How the electrodes attach
A Life Expert 3 scan uses clip electrodes at both wrists and both ankles, plus a contact band on the head. The manufacturer's checklist has you moisten the skin at each contact point with a little water first, and the electrodes with the red markings go on the right side of the body. Knowing this in advance makes setup faster and less fiddly for a first-timer.
The evening before
- No alcohol for two to three days before a scan, and no smoking the day before if you can manage it without stress. Both are on the manufacturer's own checklist.
- Eat normally and scan about two hours after a meal, neither hungry nor full. No chocolate, citrus or chewing gum right before. Mornings are best.
- Aim for a normal night's sleep; severe sleep debt dominates a reading.
- If you take regular medication, keep your normal routine. Never stop or change a prescription before a scan without talking to your doctor first, a scan is never worth interrupting real medical care.
On the day
- Hydrate normally. The body conducts through water; arriving dehydrated muddies the signal. Don't overcorrect with litres either.
- Skip coffee and strong tea beforehand. They are on the manufacturer's avoid list, along with spicy food. An espresso right before reads as arousal, not as you.
- Clean skin at the contact points. Wash hands and feet and skip creams, lotions or oils there, residue on the skin interferes with electrode contact.
- Take off all metal. Watch, rings, jewellery, belt buckle. Phone switched off or two metres away. Natural-fibre clothing helps too.
- Set your phone aside and settle for two quiet minutes seated before starting; rushing in from stress reads as stress.
The habit that outweighs everything
Consistency. Same rough time of day, similar hydration, the same preparation, every time. Comparable conditions are what turn a series of scans into a trend that can be trusted, and the trend is the product. One-off readings are curiosities; trends are information.
