For seniors with fatty liver, diabetes, or metabolic issues, that abrupt shift may aggravate inflammation and liver strain.
Some older adults also carry inactive hepatitis; in rare cases, extra physiologic stress can contribute to flare-ups.
Existing liver disease (like cirrhosis) adds risk: hot, prolonged morning soaks may worsen swelling, fatigue, or precipitate complications. Rapid temperature changes can also disrupt bile flow, irritating gallbladder or bile-duct problems.
Safer routine: rehydrate first, wait at least an hour after waking, choose lukewarm water, and keep baths to 10–15 minutes. If you have liver, heart, or blood-pressure conditions, ask your clinician what bath/shower habits are safest for you.
