The linked video asks whether bathing time affects immunity. The sources cited here do not establish that bathing at a particular time raises or lowers immunity, so they should not be used to conclude that morning or evening is right for everyone. Here, the focus is reducing accidents while bathing and preventing falls.
What the safety guidance says
Japan’s Consumer Affairs Agency has published guidance on preventing bathing accidents among older adults, especially in winter. It advises warming the changing area and bathroom before bathing, standing up from the tub carefully, and letting someone at home know before bathing. The Japanese guidance gives a water temperature of no more than 41°C and a bath time of no more than 10 minutes as guidelines for accident prevention in its local context. They are not a treatment prescription or individualized advice for people in Thailand.
Reduce the risk of slips and falls in the bathroom
- Install secure grab bars where they can provide support, and consider a shower chair if standing is unsteady.
- Use non-slip surfaces, wipe up water, and remove rugs that can slide from walking paths.
- Use lighting that makes the floor and doorway easy to see. Keep supplies within reach so you do not need to climb or stretch.
- If you have fallen before, feel dizzy, or have limited mobility, ask a healthcare professional to assess the home and discuss suitable support.
The U.S. National Institute on Aging recommends home changes to help reduce fall risks, including non-slip surfaces, grab bars, and good lighting. This is general safety guidance; it does not specify a bathing time or treat immune problems.
What to keep in mind
The cited information does not establish that bathing time changes immunity. If an older adult has a medical condition, takes medication, or feels faint while bathing, ask a clinician or caregiver familiar with their health history. Do not apply guidance from another country without considering the person’s circumstances and environment.
