Gentle heat people use to ease tension and unwind.
Drink water before you start — heat draws out fluid and you'll want to replace it.
Begin with 10–15 minutes at a comfortable temperature. Warmth should feel relaxing, never distressing.
Lightheadedness, a racing heart, or discomfort means step out. Heat is not a test of endurance.
Rest, cool gradually, and drink water afterward. Skip heat sessions if you're unwell, pregnant, or advised against them.
