Is anyone having trouble sleeping at night and feeling groggy during the day lately? If you do not feel refreshed even after sleeping in and keep feeling lethargic, it might not be simple fatigue. Could your body rhythm be faltering because of the season?

When you open your eyes in the morning, does your entire body feel heavy as lead and unrefreshed, making you wonder, 'Did I even sleep at all?' If you spend the night tossing, turning, and waking repeatedly, and during the day you struggle to focus on important tasks due to overwhelming sleepiness, it is time to listen to the SOS signal your body is sending.
