Sleep loss can make chronic health conditions more of a challenge to cope with. Sleep disorders can also contribute to depression, and some sleep disorders increase the risk for other health conditions including cardiovascular disease. Fortunately, many people can improve their sleep quality through self-management and/or the use of various appliances to address sleep apnea. See our sleep tips, followed by our tools and resources that may help with your sleep challenges.
Ten Sleep Tips – In Sickness and in Health
Keep a regular sleep schedule
The sleep-wake cycle is regulated by two factors – i) a "circadian clock" in the brain and ii) the body's need to obtain sleep after a period of wakefulness. Particularly as we age, it is beneficial to go to bed and get up at the same time each and every day - improves both sleep performance and sleep quality throughout the week. Keep track of your sleep times with a sleep diary.
Caffeine is a stimulant and is commonly used for its alerting effect. Caffeine products, such as coffee, tea, colas and chocolate, remain in the body on average from 3 to 5 hours, but the stimulant effect may affect some people for as long as 12 hours. Even if you do not think the caffeine affects you, it may be disrupting your sleep. Avoiding caffeine within 6 hours of going to bed improves sleep quality.
Nicotine is also a stimulant. Smoking before bed makes it more difficult to fall asleep. Nicotine can cause difficulty falling asleep. Then, when smokers go to sleep, they experience withdrawal symptoms from nicotine, which cause arousals (lighter sleep) and awakenings.
Although many people think of alcohol as a sleep aid because of its sedating effect, it actually disrupts sleep causing nighttime awakenings. Consuming alcohol leads to a night of less restful sleep both due to the withdrawal effects and because its diuretic effects require more bathroom visits.
Don't eat or drink too much close to bedtime
Over-eating or drinking may make you less comfortable when settling down for bed. Spicy foods may cause heartburn, which leads to difficulty falling asleep and discomfort during the night. Restrict fluids close to bedtime to prevent mid-night bathroom visits.
Exercise at the right time promotes sleep
Aerobic exercise at the right time can make it easier to fall asleep and contribute to sounder sleep. But be careful! Exercising right before going to bed can make falling asleep more difficult by making you more alert and raising your body temperature. For these reasons, try and finish your exercise at least 3 hours before bedtime. Late afternoon exercise is the perfect way to help you fall asleep at night. WWDPI provides
tips on exercising and staying physically active.
Use relaxing bedtime rituals
A relaxing, routine right before bedtime sends a signal to your body that it is almost time to go to sleep. Avoid arousal activities like working and exercise that can make it more difficult to fall asleep. Try an activity that is relaxing, such as soaking in a hot tub, reading, listening to music or having a massage. If you are unable to avoid tension and stress, it may be helpful to learn relaxation therapy from a trained professional.
Create a sleep-promoting environment
Most people sleep best in an environment that is cool, quiet and dark. Check your room for noise or other distractions, including a bed partner's sleep disruptions, light and a dry or hot environment. Make sure your mattress is comfortable and supportive for you and your bed partner.
Associate your bed with sleep and sex only
Use your bed only for sleep and sex to strengthen the association between bed and sleep. If you associate a particular activity or item with anxiety about sleeping, omit it from your bedtime routine. For example, if looking at a bedroom clock makes you anxious about how much time you have before you must get up, move the clock out of sight. Do not engage in activities that cause you anxiety and prevent you from sleeping.
Limit non-sleep time in bed and reduce naps
Get into bed only when you are tired. If you do not fall asleep within 15-20 minutes, it is best to get out of bed and do another relaxing activity until you are feeling sleepy again. Generally, if you have difficulty sleeping through the night it is best to avoid naps and horizontal rests as this weakens “sleep pressure” the following night and may start a cycle of poor sleep at night caused by catching unrestorative sleep in the day.
