Night Sweats

Many people experience hot flashes and night sweats during menopause and perimenopause. The good news is there are many methods which may reduce or prevent these symptoms, we discuss lifestyle, dietary and supplemental approaches in this article.

What are night sweats and why do they occur?

Night sweats are incredibly common in people going through perimenopause and menopause, affecting around 85% of this population. According to some estimates, occurrence of menopausal hot flashes tend to run, on average, for 5.2 years [i].

Night sweats are common in menopausal and perimenopausal women because it is related to the hormonal changes which happen at this time. Declining oestrogen levels disrupt the body's temperature regulation, leading to episodes of excessive sweating during sleep[ii]. The hypothalamus becomes more sensitive to hormone fluctuations, acting on small changes as it signals to cool the body down, whilst not regulating it effectively – and triggering night sweats. Hormonal imbalances between oestrogen and progesterone further exacerbate this[iii].

Why else do we get night sweats?

Night sweats occur as a normal part of perimenopause and menopause. However, there can be a multitude of other reasons people get night sweats:

Medication side effects

Fever from illness

Thyroid disorders


And more[iv]

Hormone fluctuations in menstrual cycle: Sometimes night sweats can occur in menstrual cycles of those who are not yet in the perimenopausal stage. This can happen for various reasons such as a decline in oestrogen after ovulation[v]. Some people may experience more intense symptoms if their hormonal health is poor. In such cases, it may be common to see many other symptoms of PMS or hormonal imbalances. See our other articles on PMS and hormonal health here. Also see our functional testing section below for more details on how testing can be used to map hormones.

Please note: Night sweats can be a manifestation of many other medical conditions in various degrees of severity. If you believe your symptoms to be excessive, sudden or you’re unsure of the cause, it would be advisable that you contact your GP in order to rule out any serious conditions.

Why is nutritional therapy important for lessening and helping to prevent night sweats in menopause and perimenopause?

Nutritional therapy is an incredibly useful tool to manage menopausal/ perimenopausal symptoms such as night sweats. It can do so by supporting balance of hormones during this transitional time. Menopause and perimenopause can also be physically and emotionally challenging. A nutrient-rich diet can support overall well-being, including improved mood, energy levels, and quality of sleep.

Moreover, maintaining a healthy weight through proper nutrition can positively impact hormone balance and help reduce the severity and/ or frequency of night sweats.

Dietary suggestions for night sweats

Hormone Balance: Certain foods and nutrients can support hormone balance during menopause and perimenopause. Phytoestrogens alleviate symptoms like night sweats[xiii]. Soy products (e.g., tofu, tempeh, natto), flaxseeds, sesame seeds, and legumes contain phytoestrogens that can help modulate oestrogen levels and reduce night sweats. Balancing blood sugar levels through a diet rich in whole foods, healthy proteins and healthy fats can also contribute to hormone stability.

Nutrient Support: Adequate intake of key nutrients is essential for overall health and can help manage menopausal symptoms. Nutrients like vitamin E, vitamin B6, magnesium, and calcium have been associated with reduced frequency and severity of night sweats[xiv][xv].

Blood sugar balance: During menopause, hormone fluctuations can affect insulin sensitivity and disrupt blood sugar regulation. Declining oestrogen levels can lead to imbalances in blood sugar levels and an increased risk of insulin resistance. Thus, maintaining stable blood sugar levels through diet is very important for hormone regulation and weight management[xvi].

Balancing breakfast ideas: Ensure you have a good breakfast rich in blood sugar balancing proteins and healthy fats to set you up for the day. Try - Protein smoothie: Blend together almond milk, spinach, a scoop of protein powder, a tablespoon of nut butter, and half a frozen banana. Add ice cubes for a refreshing texture.
