Dear Iris: Clocks are Changing, Should I?

Dear Iris,

Daylight Savings is coming up and I'm wondering what I should do with taking my meds when the time changes. Do you just take your morning dose an hour early or late that first day? Or do you start adjusting a couple of days early?


Dear L, 

Navigating daylight savings time presents unique challenges, including adjusting to a new schedule. When it comes to medication timing, there's no need for any changes before the shift. Just continue with your regular routine. For instance, if you normally take your medication at 8:00 AM, do so as usual on the morning daylight savings time begins. 

While adjusting medication times might be straightforward, the transition can disrupt your body's circadian rhythm. This internal clock regulates sleep, appetite, body temperature, and other crucial functions, making the spring shift particularly jarring. 

To ease into daylight savings time, consider gradually shifting your routine the week before or a few days before. Sleep experts suggest going to bed 20 minutes earlier each night and slowly adjusting mealtimes too. This gradual approach can help your body adapt smoothly to the time change.

Missed last week? Dear Iris: I’m Managing It All
