"Sleep is the best meditation," said the Dalai Lama and ain't that the truth. Everything feels achievable after a good night's kip.
But have you ever struggled to drift off, tossed and turned all night and then tried to work the next day? It's an impossible, caffeine-fuelled task that usually ends in total exhaustion and feeling like you're rubbish full stop.
Not only does the inability to get some zzzzzz impair concentration, it also results in tired pallor and can affect digestion.
We take it for granted, but giving ourselves a good night's sleep is one of the most effective ways to bounce back after a hard day and relieve stress.
Whether it's Sunday night fear or work-related anxiety, there are ways to switch off before you snuggle down.
Susan Curtis, Natural Medicines Director of Neal's Yard Remedies, says: "There are a number of essential oils well known for their ability to help promote a restful night's sleep, with studies showing Lavender, Roman Chamomile and Ylang Ylang to be very effective to calm the mind, relax the body, and reduce levels of stress and anxiety."
She adds: "These essential oils can be used in a variety of ways, including skin creams (like Beauty Sleep Concentrate), as a bath oil just before bed (along with full fat milk or a suitable carrier oil), or by adding two-three drops to a tissue and placing it next to your pillow as your nodding off."
