The quality of your sleep directly affects your mental and physical health and the quality of your waking life, including your productivity, emotional balance, brain and heart health, immune system, creativity, vitality, and even your weight. No other activity delivers so many benefits with so little effort!

But even minimal sleep loss can take a substantial toll on your mood, energy, mental sharpness, and ability to handle stress. And over the long-term, chronic sleep loss can wreak havoc on your mental and physical health. While you rest, your brain stays busy, overseeing biological maintenance that keeps your body running in top condition, preparing you for the day ahead.

By addressing any sleep problems and making time to get the sleep you need each night, your energy, efficiency, and overall health will go up.

Fact: You may not be noticeably sleepy during the day, but losing even one hour of sleep can affect your ability to think properly and respond quickly. It also compromises your cardiovascular health, energy balance, and ability to fight infections.

Consequently, it can take more than a week to adjust after traveling across several time zones or switching to the night shift. There is a big difference between the amount of sleep you can get by on and the amount you need to function optimally. According to the National Institutes of Health, the average adult sleeps less than seven hours per night.

While sleep requirements vary slightly from person to person, most healthy adults need between 7 to 9 hours of sleep per night to function at their best. Children and teens need even more. And despite the notion that our sleep needs decrease with age, most older people still need at least 7 hours of sleep.

Since older adults often have trouble sleeping this long at night, daytime naps can help fill in the gap. Think again. Researchers at the University of California, San Francisco, discovered that some people have a gene that enables them to function well on six hours of sleep a night. If you give yourself plenty of time for sleep but still have trouble waking up in the morning or staying alert all day, you may not be spending enough time in the different stages of sleep.

Each stage of sleep in your sleep cycle offers different benefits. You can ensure you get more deep sleep by avoiding alcohol, nicotine, and being woken during the night by noise or light. While improving your overall sleep will increase REM sleep, you can also try sleeping an extra 30 minutes to an hour in the morning, when REM sleep stages are longer.

How is it possible to be sleep deprived without knowing it? Most of the signs of sleep deprivation are much more subtle than falling face first into your dinner plate. Lack of sleep affects your judgment, coordination, and reaction times. In fact, sleep deprivation can affect you just as much as being drunk. Sleep deprivation has a direct link to overeating and weight gain. There are two hormones in your body that regulate normal feelings of hunger and fullness.

Ghrelin stimulates appetite, while leptin sends signals to the brain when you are full. So, the more sleep you lose, the more food your body will crave. Rule out medical causes for your sleep problems. A sleep disturbance may be a symptom of a physical or mental health issue , or a side-effect of certain medications.

Stick to a regular sleep schedule. Support your biological clock by going to bed and getting up at the same time every day, including weekends. Get regular exercise. Regular exercise can improve the symptoms of many sleep disorders and problems.

Aim for 30 minutes or more of activity on most days—but not too close to bedtime. Be smart about what you eat and drink. Get help with stress management. Improve your sleep environment. Keep your bedroom dark, quiet, and cool, and reserve your bed for just sleeping and sex. Develop a relaxing bedtime routine. Avoid screens, work, and stressful conversations late at night. Postpone worrying.
