Hormone Highs and Lows Follow a Seasonal Pattern

Hormone Highs and Lows Follow a Seasonal Pattern

Hormones can surge and drop within minutes to direct many of our daily functions: sleep, digestion, reactions to stress. General hormone levels rise and fall slightly across the year as well. New work shows that the pattern has a seasonal memory of sorts, too, governed by a newly discovered internal clock. Each maximum or minimum causes hormone levels to rise or fall by several percent—small but significant—though often several months later.
