Many women experience low energy and sluggishness during periods. This happens because the menstrual cycle affects energy levels in numerous ways, such as hormonal fluctuations, mental fatigue, and more. Tap to know more!

Hormonal Fluctuations

During menstruation, the hormones like oestrogen and progesterone fluctuate, leading to mood swings, fatigue, and energy crashes.

Increased Inflammation

When women are on periods, uterine prostaglandin, a hormone is released that may trigger a mild inflammation, leading to cramps, fatigue, and more.

Bloating

During luteal phase, the hormonal fluctuations, especially progesterone can cause fluid retention that can lead to bloating, making you sluggish and heavy.

Mental Fatigue

Periods can also cause mental fatigue as the serotonin levels are lowered, resulting in anxiety, brain fog, exhaustion, and more.

Sleep Disturbances

Many women may experience sleep disturbances due to various reasons like hormonal imbalance, cramps, and more, which can cause daytime fatigue.
