This year, on the second Sunday of March, most of the country will move their clocks one hour ahead, marking the beginning of Daylight Saving Time. This effectively moves one hour of daylight from the morning to the evening, giving us longer summer nights. But waking up the following Monday morning may not be so easy, having lost an hour of sleep. How these time changes will affect you depends on your own personal sleep habits, and lifestyle.\n\u201cThe fundamental problem we have in our current 24\/7 society is that everyone is already experiencing some sleep deprivation,\u201d says Patrick J. Strollo Jr., MD, Medical Director of the University of Pittsburgh\u2019s Sleep Disorder Program. \u201cWhen we make even small adjustments in sleep schedules, that can have a negative impact.\u201d\nMoving our clocks in either direction changes how much our bodies\u00a0are exposed to light, which is the principal factor for setting and resetting our 24-hour natural cycle, or circadian rhythm. In doing so, our internal clock becomes out of sync with our current day-night cycle. An unwritten rule is that it will take about one day for your body to adjust for each hour of time change. However, this might vary by individual.\nWhat can you do to reset your internal clock to adapt more quickly to the time changes? Your 24 hour natural cycle is internally generated but it can also be influenced by the environment, behavior, and medications. Here are some steps you can take to avoid sleep deprivation and help ease the transition to the time change.\n4 Steps to Adjust to the Time Change\n1.) Light is the dominant environmental cue. Light suppresses the secretion of the sleep-inducing hormone melatonin. So it is important to expose yourself to the light as much as possible while you are awake, and to limit your exposure to bright light when it is dark outside. For example, if you get up at night to go to the bathroom, you should not turn on the light. Prepare beforehand by placing a night light in the bathroom.\n2.) Plan ahead. Make the time change incrementally by setting your alarm clock 15 minutes earlier and earlier for five consecutive days. So, when the time change actually hits, you\u2019re already there.\n3.) Create sleep-friendly environments to increase your chances of falling asleep easier, staying asleep longer, and sleeping more soundly. Try to reduce or eliminate consuming caffeine and alcohol, and avoid exercising before bedtime. Establish relaxing rituals before bed to gradually calm yourself such as taking a hot bath, and wearing ear plugs and\/or eye masks.\n4.) Get some exercise. Exercise helps advance the body clock, just as bright light exposure does. Exercise also raises your body temperature and helps you feel more energized.
