Sleep is vital to our lives. Although it seems to be a pretty simple thing (since you just close your eyes and then fall asleep), scientists have been trying for years to understand how we sleep. Despite the excellent progression, we still don’t know everything about how our bodies fall asleep.
Nowadays, many people have insomnia. It is okay to be busy and have no time to sleep for some days, but, unfortunately, some people can’t control that, and they just can’t sleep. Insomnia doesn’t only mean that you can’t fall asleep, but the inability to maintain proper sleep length is also considered insomnia.
Insomnia can be transient, which means that it happens due to current situations like stress, pain, menopause, or disease. It can also be chronic, which is commonly seen in the elderly. Genetic factors also play a role. So far, scientists have identified 7 genes that can predispose someone to insomnia . Insomnia can also be due to the consumption of heavy meals before sleep or caffeine-rich drinks like coffee, tea, and cocoa.
Unfortunately, lack of sleep, whether on purpose or not, as in insomnia, has drawbacks. They include:

Studies found that magnesium deficiency is associated with more risk of insomnia as magnesium plays a role in neuronal firing. Different studies agree that food high in magnesium can lead to better sleep .
You may also try magnesium supplementation, but this should be under the supervision of a nutrition expert or your physician. In general, you shouldn’t take more than 350 mg. 
You may consider vitamin D supplementation. Studies found that Vitamin D supplementation improved sleep quality in patients with insomnia. Consider taking it as a supplement or get exposed to the sun for ~15 minutes daily to allow your body to create its vitamin D .
Multiple studies agreed that lavender could help insomnia patients improve sleep quality and relieve stress and anxiety. You may take it as a supplement or in any form you like. You should be aware that some studies found that it can cause gynecomastia in men because it has an estrogen-like effect. So, if you are a male and started to note enlargement of your breast or a female and have a family history of breast cancer, it is better to stay away from it .
Different habits have been shown to reduce the severity and frequency of insomnia.
Try to make sure that you use the bed only for sleeping. It would help if you didn’t do any mental work like studying or working in bed. With time, this will teach your brain that it is time to sleep once you are in bed.
Having a consistent schedule will help your brain determine when to sleep and when to wake up. If you go to bed, let’s say, at 11:00 PM daily for a few weeks, you will find yourself sleepy every day around this time. This is because your brain now knows that it is time to sleep!
Exercise can be helpful, especially during times of stress, and this can decrease your anxiety and depression. Also, studies found that more physical activity/exercise during the day is correlated with better sleep .
Exposure to light before sleep is associated with disruption of the sleep cycle, insomnia, and anxiety. Try to avoid bright lights and smart devices (laptop/phone) at least 1 hour before sleep. This is because the light is found to disrupt melatonin levels .
In addition to things to do, there is a list of things you should avoid before sleep.
Although caffeine is generally healthy and has positive effects on our body, like enhancing our mood, caffeine has been shown to block some receptors in your brain that are associated with feeling sleep. These receptors are called adenosine receptors.
No matter how long you have been drinking caffeine, limiting caffeine a few hours before sleep would be best.
Avoid eating fatty meals like pizzas or cheeseburgers before sleep. These things can lower your sleep quality by making you more likely to wake up during sleep or even make you unable to sleep.
Even though we mentioned that exercise could help make you sleep better, it is recommended that you exercise during the day, not right away before sleep. This is because exercise raises your adrenaline levels, which is associated with more sympathetic activity and awareness.
Insomnia is common among older people, and it is associated with adverse effects like depressed mode, anxiety, and immune dysfunction. Different things have been scientifically proven to improve sleep, like magnesium-rich food, lavender, and vitamin D. Moreover, exercise, a consistent sleep schedule, bed only for sleep, and avoiding caffeine, light, and heavy meals can significantly improve your insomnia.
