Here some list of the plants that may help you to sleep at night.

snake plant

The snake plant is a natural air purifier. It emits oxygen at night that helps you sleep better. It’s also known to remove some harmful chemicals from the air such as xylene, trichloroethylene, toluene, benzene and formaldehyde. Formaldehyde is often found in hairspray and can cause respiratory problems.

Lavender

The smell of lavender is recognised everywhere as a great aid for relaxation. Lavender has been proven to lower our heart rate, blood pressure and stress levels, which is why it’s perfect for the bedroom. It’s one of the most renowned plants to help you sleep.

Peace Lily

Air that is too damp can cause plenty of problems, but dry air can also be an issue for sleep. If your bedroom has an issue with dry air, you might be better using a peace lily. These lilies can increase your bedroom’s humidity by up to 5%, which is known to decrease dry skin and hair, static electricity, and increased susceptibility to colds.

Aloe

Aloe is a popular plant in most households, famous for its ability to soothe minor cuts, burns, bites and dry skin. Aloe vera makes oxygen at night-time, which is great for your bedroom’s environment. Aloe likes a lot of sun, so keep it in the window next to your lavender.

English Ivy

Another high-ranking air-purifier according to NASA, English Ivy is great for those who have allergies, asthma or anyone looking for cleaner air and a better night sleep. It's easy to grow and doesn't need much light, but it's another one that can be toxic if eaten by small children and pets, so it's a good thing English Ivy to put in out of reach.
