Shower steamers provide aromatherapy benefits through essential oils released in the shower steam. They can help with relaxation, energy boost, congestion relief, or mood enhancement depending on the scent blend. They're generally safe for most people, but those with respiratory conditions, allergies to specific essential oils, or pregnant women should consult with a healthcare provider before use. Always ensure good ventilation in your bathroom, and discontinue use if you experience any irritation or breathing difficulties.
