As good for your mood as they are for your body, baths can become addictive in winter, but that's no bad thing.
The four essential ingredients for a super soak?
You'll need a candle, soothing music or a podcast, wine (or tea if you're abstaining this month), and something delightfully fragranced to pour into the steaming tub.
Turn your bathroom into a spa-like sanctuary with these bathing beauties.
The most luxurious way to scent your soak, bath oils dissipate in hot water, releasing the fragrance and creating a moisturising film that clings to your skin.
They may be more expensive, but you only need a splash, and the potent aroma of essential oils can be invigorating (citrus and ginger) or slumber-inducing (lavender works wonders before bedtime).

If soothing aching limbs and cold symptoms is your top priority in the tub, bath salts are what you need.
A capful of the clever crystals in a hot bath will relieve muscle tension, plus the salt draws out moisture to reduce bloating, while the vapours help clear airways.

For the ultimate in relaxation, a frothy bubble bath will make you feel like you're floating on a cloud.
Lavish, oil-infused bath foams offer skin-softening properties too - but if you're feeling the pinch this month, cheap-as-chips bubble bath will do the trick.

Prolong that post-bath Zen by lathering up with a body lotion - particularly important if you're partial to a piping-hot soak that can leave your skin dry.
Gourmand scents, like vanilla and tonka bean are real mood-boosters, while ingredients like shea butter and argan oil will soften and restore moisture.
