Keeping a Sleep Diary

A diary is written to record the happenings of a day. Similarly, a sleep diary aims to help you keep a track of your sleep-wake cycle and some details related to it, such as those mentioned above.

This sleep diary is to be filled for some weeks by yourself or your guardian. 

A sleep diary, also known as a sleep log, is used by the health practitioners, therapists and the clients to record their sleep for treating sleep disorders especially circadian rhythm sleep disorders, by identifying faulty sleep patterns and habits to improve sleep.

Other than this, a sleep diary is also useful for medical professionals for helping individuals to keep a track of their sleep habits, patterns and work on improving them by themselves. 

Why Should You Keep A Sleep Diary?

A sleep dry must be kept for the following major reasons, 

1. It Will Give You a Better Idea of Your Sleep Patterns and Habits

Sleep disorders are very common in today’s time. Often people think they experience sleep disorder due to the trouble they face while sleeping.

This is not necessarily true. Sleep disorders can also be a result of unhealthy sleep habits. Intake of high amounts of alcohol or caffeine before going to bed can affect your sleep.

People who have unhealthy sleep habits are diagnosed with insufficient sleep syndrome.

This is due to the problems they face while falling asleep because of the adverse effects of unhealthy eating and sleep habits they have.

You can work on your sleep by keeping a sleep diary.

A sleep diary helps you keep a track of your sleeping habits, patterns, and behaviors so you can easily identify the unhealthy diet and conducts that are affecting your sleep, work on them and improve your sleep. 

Recognizing the pattern of your sleep and your unhealthy behaviors can aid you to change your habits and observe their effect over the period of a week.

If your sleep is improved it means the new habits are good for your sleep and well-being.

If not, you can alter the habits again until you discern a noticeable, positive change in your sleep patterns.

2. You Will Get Proactive About Your Sleep

Having a sleep diary will aid you in identifying the effect of sleep in your daily life activities.

This will help you recognize the importance of sleep and you will work on promoting your sleep habits willingly and with full determination.

Your sleep diary will enable you to focus on the effects of your unhealthy diet such as the consumption of caffeine and alcohol, and harmful sleep patterns such as using mobile phones in bed before going to sleep.

You will be able to notice the impact of these things on your sleep and normal functioning and thus you will feel motivated to change your habits such as by replacing caffeinated drinks with chamomile tea, tart cherry juice, almond milk etcetera to help you improve your sleep. 

A sleep diary would also help you keep a track of the drinks you took before going to bed and whether they were helpful for you in sleeping or they disturb your sleep, making you wake up weary and tired. 

A sleep diary would help you identify the impact of doing exercise or work out on your sleep.

You will observe physical activity has improved your sleep and this would encourage you to continue these healthy habits.

Thus, keeping a track of your sleep habits and patterns would help you identify which behaviors you need to skip, which ones you need to modify and which ones you need to enhance, to help you promote your sleep.

3. It Can Help Your Doctor Give You A Proper Diagnosis

A sleep diary helps you modify your unhealthy behaviors that are interrupting your good, sufficient and healthy sleep.

If you still feel your altered behaviors are not helpful for you in improving your sleep, you can consult your physician, a therapist or a sleep specialist. Oftentimes doctors fail to identify the real cause of sleep disorders.

Most of the time the women with sleep apnea are diagnosed with insomnia. This could be due to various reasons.

One reason for this misdiagnosis is that the doctor is not a sleep specialist, he has a preconception about the way sleep apnea patients look like: middle-aged, overweight male with less than 17 inches neck.

Sleep apnea diagnosed women are not as severe as men and their snoring is also lighter as compared to that of men with tricky breathing cessations and short-living apnea events.

In addition to it, the men are also less observant about their partner’s sleep habits since women rarely acknowledge they are having breathing issues at night.   

Another reason for this misdiagnosis is misreporting on the part of the patient. Patients may inform their doctor about other symptoms that are causes of insomnia rather than any other sleep disorder.

The most common symptoms told by patients include fatigue, mood fluctuations and problems in falling asleep. 

A sleep diary can help the doctor identify the correct sleep disorder so he can give the treatment according to it. 

4. You Can Monitor the Effectiveness of Your Treatment

Misguidance on the part of the doctor can also make him diagnose individuals with sleep apnea and recommend continuous positive airway pressure (CPAP) therapy as a treatment.

This therapy often seems troublesome for the patients and they discontinue taking the therapy due to the inability to tolerate the air pressure. 

Continuous use of a sleep diary even during the treatment can help you identify the effectiveness of the treatment.

If the treatment is bringing a change in your sleep pattern in a positive way, that means it is effective, this would motivate you to continue taking the treatment and if it is not producing fruitful results then you can consult your doctor again.
