Sleep is unarguably one of the most important factors governing your overall health, but there are millions of people in this world who have trouble getting a good night’s rest.

While some of the reasons for insomnia are poor diet, the lack of a bedtime routine, decreased physical activity, and overconsumption of caffeine, other reasons you can’t sleep through the night might surprise you.

Here are five things to consider addressing if you have trouble sleeping.

1. Sleeping next to pets

If you have pets such as dogs and cats, chances are you allow them to cuddle up next to you in your bed at night. While comfortably snuggling with your fur babies is known to reduce stress and anxiety, it doesn’t always lead to a good night’s sleep.

Let us take the example of cats. Cats have different sleep-wake cycles than humans, so allowing them to sleep on your bed might wake you up at odd hours. Studies show that cats can be as disruptive to sleep as humans sharing a bed.

Try to regulate cuddling with your pets to daylight hours, and train them not to enter your bed when you call it a night.

2. Being on medication

Chemicals potentially have a profound effect on your sleep-wake cycle. Regardless of whether you’re reaching into your medicine cabinet to treat the common cold or to take your daily anti-hypertension pill, it is important to be aware that certain medications could make it difficult for you to fall or stay asleep.

Certain medications could keep you awake at night. Speak with your doctor if you feel overwhelmed with a lack of sleep; they might switch you to a lower dosage.

3. Sleeping on an old mattress

If you have tried several remedies and still cannot find the reason why you can’t sleep through the night, it might be time to look into your mattress. An old mattress is unable to support your body weight and over time, it wears on the pressure points of your body. Consequently, the blood flow to one side of your body could decrease, causing discomfort in sleep. This creates aches and fatigue the next morning.

A study on elderly people revealed that those who slept on uncomfortable mattresses experienced higher degrees of insomnia. Regardless of your age, your mattress should be neither too firm nor too soft for an ideal night’s rest. Choose wisely when you purchase your next mattress and change it out every 10-15 years.

4. Dealing with allergies

Nasal allergies affect almost everyone. With changing seasons, especially in spring with pollen flying everywhere, it’s important to be protective of your sleep. Apart from seasonal variations, allergies caused by indoor dust mites and air pollution might also keep you up, as per research.

To reduce allergies, it’s recommended to keep windows closed and remove pollen from your clothes and hair. Although antihistamines could help you combat allergies, they have other side effects. Other ways to prevent allergies are to clean your bed often and take a quick, warm shower before bedtime.

5. Drinking a nightcap

Although a glass of wine or nightcap may help you doze off faster, according to the National Sleep Foundation, it can cause wake-ups later in the night as your body metabolizes the alcohol, inhibiting restorative sleep. It can also cause your body temperature to rise, leading to vivid dreams or sleep terrors, aggravating breathing problems, and resulting in restless legs, all of which contribute to poor quality of sleep.

6. Living near a busy street

One reason the urban population struggles to sleep through the night is that the busy nightlife is a hindrance to peaceful slumber.

It gets worse if you live by a busy street with vehicles plying all through the night, as revealed by a World Health Organization (WHO) guideline study. Noise from a busy street could be a major sleep disruptor.

If moving is not an option, try to use sleeping aids like earplugs and white noise machines to keep the noise at bay.
