🛁 What the research found

Scientists in Japan discovered that taking a hot bath before bedtime can significantly improve sleep quality in older people. Adults who soaked in warm water before bed fell asleep more easily and had deeper, more restful sleep compared to those who didn’t bathe before sleeping.

🔥 How it works

Here’s what the study highlighted:

• The ideal bath temperature was around 40–41 °C (warm but not scalding). Too hot — above about 41.7 °C — or bathing too long actually reduced the benefits.
  
  
• The best timing was 1–2 hours before bedtime. This allows the body’s core temperature to gradually drop, which helps trigger natural sleep mechanisms.
  
  
• A warm bath helps relax muscles, improve circulation, and reduce stress responses — all of which can support falling asleep and staying asleep.
  
  

🧠 Why it matters

Poor sleep becomes more common as we age and can impact mood, memory, balance, and overall health. A simple habit like a warm bath may be an easy, low-cost way for many older adults to enjoy better sleep quality — especially in colder months.

💤 Other sleep-friendly habits (context)

In general, good sleep habits often include setting a regular bedtime routine, keeping sleep environments cool and dark, winding down before bed, and limiting caffeine or heavy meals late in the day — all part of good “sleep hygiene.”
