Foods that may trigger heavy night sweats are alcohol, spicy foods, and items with caffeine. Diets with high fat and sugar content and foods and drinks hot enough to raise the body's temperature also cause night sweats.
People prone to night sweats should avoid foods that trigger the condition prior to bedtime. In some cases, doctors recommend eliminating these foods from the diet entirely. Diets featuring whole grains, vegetables, fruits and a limited amount of healthy fats are not associated with night sweats. Legumes, fruits and vegetables provide natural sources of estrogen that may help curb the development of heavy night sweats.
When snacking close to bedtime, reach for healthier alternatives. If something sweet is desired, substitute candy with a piece of fruit or a sweet potato. Trade coffee for caffeine-free tea. Avoid hot spices when seasoning foods; instead, try oregano or basil.
Night sweats are hot flashes that produce an extreme amount of sweat, sometimes soaking through pajamas and sheets. Common triggers outside of food include warm weather, sleeping under too many blankets, and raising the body's temperature by exercising prior to bedtime. While the occasional bout of night sweats is not something to cause alarm, episodes that occur regularly, decrease sleep quality, or occur alongside fever and weight loss require consultation with a medical professional. Night sweats may indicate cancer or occur as a symptom of menopause, hypoglycemia, hormone disorders, infections and anxiety.
