Baths are soothing, but timing and temperature matter more after 70. Overnight, circulation and hydration dip; jumping into a hot bath first thing can cause sudden vessel dilation and blood-pressure swings that stress the body—potentially diverting blood away from vital organs like the liver.

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.
